Choosing the Right Water Birth Pool: Why Performance Matters More Than Price

A practical guide for hospitals, birth centres, architects and maternity teams planning a safer, more durable and better-performing birthing environment.

When planning a new maternity unit or upgrading an existing birthing room, budget is always part of the conversation. Every hospital needs to make responsible purchasing decisions, justify investment and demonstrate long-term value.

But when it comes to choosing a water birth pool, the lowest purchase price is rarely the best measure of value.

A water birth pool is not simply a large bath. It is a specialist item of hospital sanitary ware used in a demanding maternity environment. It must support mothers safely during labour and birth, give midwives practical access and protection, meet infection-control expectations, withstand repeated clinical use and remain reliable for many years. [8, 10]

That is why performance matters more than price.

The real value of a birth pool is measured over its working life

The initial cost of a water birth pool is only one part of the decision. The more important question is how well the pool performs throughout its full working life.

A well-designed pool should help reduce risk, support safe working postures, be easy to clean, resist damage, retain its appearance and help the room function smoothly for mothers, midwives, estates teams and cleaning staff. [6, 7, 8]

A lower-cost pool may look attractive at the point of purchase, but if it is harder to clean, less durable, less supportive for mothers or more difficult for midwives to work around, the apparent saving can quickly disappear.

True value is created by safety, reliability, usability and longevity.

Designed for maternity care, not adapted from ordinary bathing

Water birth places very specific demands on the pool. Mothers need space to move, rest, lean, kneel, sit, squat and change position instinctively. Midwives need clear access, good visibility and the ability to provide care without excessive bending, reaching or twisting.

This is where purpose-designed maternity pools differ from ordinary baths or general bathing products. The shape, rim height, internal supports, handholds, steps, drainage, fittings and surrounding access all affect how the pool works in practice.

Active Birth Pools are designed specifically for maternity environments. The aim is to support physiological labour, encourage upright and active positions, and give midwives the practical working conditions they need around the pool. [1, 4, 5]

Safety should be built into the design

The safest birth pools are not made safe by adding accessories afterwards. Safety needs to be built into the pool from the beginning.

The wide, softly contoured rims on Active Birth Pools provide support for mothers and help cushion midwives’ forearms during extended periods of care. Recessed handgrips give mothers secure places to hold without creating unnecessary obstructions. Smooth internal forms help mothers reposition naturally and find comfort in the water. [1]

These details may appear simple, but in daily clinical use they make a meaningful difference. Good design helps the mother feel secure and supported while helping staff work more safely and effectively.

The importance of safe entry and exit

Entering and leaving the pool are among the most important moments in water birth practice. A woman in labour should not have to climb awkward steps, negotiate a high rim or rely heavily on staff support.

Active Birth Pools are designed around the “sit and swivel” principle. The mother can sit on the wide rim, turn safely and lower herself into the water while maintaining stable contact. This simple approach supports dignity, reduces unnecessary strain and helps avoid the risks associated with climbing or over-assistance. [1]

A single, moveable step can provide height support when needed without creating permanent obstructions around the pool. This benefits both mothers and midwives by keeping access clear and reducing trip hazards.

Midwives need protection too

A water birth pool must work for the people providing care as well as the person giving birth.

Midwives may spend long periods beside the pool, observing, reassuring, supporting, monitoring and responding to changing circumstances. If the pool is too wide, too deep, poorly shaped or difficult to approach, staff can be exposed to avoidable bending, twisting and overreaching.

Active Birth Pools are shaped to give midwives practical access and supportive working positions. Wide rims, clear floor space, rounded contours and unobstructed access help reduce physical strain and make it easier to care for the mother in the water. [1, 6, 7]

This is not only a comfort issue. In busy maternity settings, better ergonomics support safer working practices and more sustainable care.

Hygiene and cleanability are essential

In a hospital environment, cleanability is a core performance requirement. A birth pool must be easy to clean thoroughly between uses, with smooth surfaces, minimal dirt traps and details that support infection-control practice. [8, 9]

Active Birth Pools use seamless one-piece construction and smooth, non-porous Ficore® composite surfaces. The design avoids unnecessary rim-mounted fittings and surface obstructions wherever possible, helping reduce areas where contamination could accumulate. [1, 2, 3, 8]

This approach treats hygiene as part of the design, rather than as an afterthought. The result is a pool that is easier for staff to clean and better suited to repeated clinical use.

Why material choice matters

The material a pool is made from affects its strength, surface quality, heat retention, durability, cleanability and long-term appearance.

Active Birth Pools are made from Ficore®, a proprietary solid composite developed by Design & Form (our manufacturers) . Ficore is not acrylic, fibreglass, gel-coated laminate or a thin surface bonded over a weaker core. It is a strong, solid composite that allows refined ergonomic shapes, seamless construction and durable integrated features. [2, 3]

For hospitals, this matters because birth pools are exposed to warm water, body weight, repeated cleaning, frequent disinfection and intensive use. A material that resists wear, retains its finish and can be repaired if damaged helps protect the long-term value of the investment. [2, 3, 8]

Built to last for decades

Active Birth Pools are built to order in England and engineered for long-term service in demanding maternity environments. Their seamless one-piece construction, double-wall engineering, integrated features and durable Ficore® composite structure are designed to provide strength, stability and reliability over many years of use. [1, 2]

They are built to last for decades and backed by a lifetime guarantee. [1]

That lifetime guarantee reflects confidence in the material, the manufacturing process and the engineering behind every pool. For hospitals, this means fewer replacement concerns, less disruption and better whole-life value.

Emergency evacuation must be considered from the start

Emergency evacuation from a birth pool is rare, but the pool must be designed with that possibility in mind.

The wide rims, internal support features and unobstructed access around Active Birth Pools help staff respond more effectively if a mother needs assistance leaving the pool. The absence of unnecessary rim-mounted metalwork or obstructing fittings also supports safer movement around and over the rim when rapid access is required. [1]

Good emergency planning begins with good design.

A better pool supports a better birthing room

The birth pool is often the focal point of a birthing room. Its design affects the atmosphere of the space, the ease of movement around the room, the plumbing layout, cleaning routines, emergency access and the way mothers and midwives interact during labour.

Choosing the right pool helps create a calmer, safer and more practical environment. Choosing a pool based mainly on initial price can create compromises that affect the room for years.

For architects, estates teams, maternity managers and midwives, the best decision is one that balances immediate budget with long-term performance.

What to consider when comparing water birth pools

When reviewing options, it is worth asking:

  • Is the pool designed specifically for labour and birth?
  • Does it support upright, active and instinctive maternal positions?
  • Can the mother enter and leave the pool safely and with dignity?
  • Can midwives work around the pool without excessive bending, twisting or overreaching?
  • Are the surfaces smooth, non-porous and easy to clean?
  • Are fittings, handgrips and controls positioned to reduce obstruction and dirt traps?
  • Is the material strong, durable and repairable?
  • Does the pool support emergency evaqcuation if needed?
  • Is technical information available for architects, planners and estates teams?
  • Is the pool built for long-term use and backed by a meaningful guarantee?

Price matters. But in a maternity environment, performance matters more.

A well-designed water birth pool supports mothers during labour, protects midwives in their work, helps hospitals maintain high standards of hygiene and remains dependable year after year.

Active Birth Pools combine Ficore® composite, ergonomic design and bespoke engineering to create hospital-grade water birth pools that deliver safety, comfort, durability and long-term value. [1, 2, 3]

For maternity units planning new facilities or upgrading existing rooms, the right choice is not simply the cheapest pool. It is the pool that performs best for mothers, midwives and hospitals over its full working life.

How to Choose a Water Birth Pool for a Hospital

A practical buyer’s guide for maternity units, procurement teams, architects, estates departments and healthcare planners.

A hospital water birth pool should be selected as part of the complete clinical environment. Size and appearance matter, but so do maternal movement, midwife access, infection prevention, water safety, entry and exit, emergency planning, installation, durability and whole-life value.

Choose the pool as part of the complete birth environment

Choosing a water birth pool for a hospital is not simply a question of selecting a shape that fits the room. The pool becomes part of the maternity team’s everyday working environment. It must support the mother’s freedom of movement, allow midwives to observe and assist without unnecessary strain, and fit the hospital’s requirements for hygiene, water safety, maintenance and emergency response. [1,2]

The strongest procurement decisions are made when maternity staff, infection-prevention specialists, estates teams, manual-handling advisers, architects and the supplier are involved before the room and services are finalised. This makes it possible to select the right model first and then coordinate the space, plumbing, drainage, access and finishes around it. [3,4]

Active Birth Pools are purpose-designed hospital sanitary products, made by hand to order in England from Ficore® composite. The range includes three sizes, each available in a wall-mounted II configuration or a freestanding 360° configuration. [5,6]

Start with the maternity unit’s needs

Before comparing models, define how the pool will be used. A pool intended for an alongside midwifery unit may be used differently from one placed in an obstetric-led environment, a small refurbishment or a large new-build room. The intended model of care should guide the specification.

  • Estimate how frequently the pool is likely to be used and whether it will serve one room or form part of a larger water birth service.
  • Confirm the available room area, the position of the bed or trolley, door routes, storage and emergency equipment.
  • Identify the positions from which midwives need to observe, support and assist the mother.
  • Consider how the mother will approach, enter, move within and leave the pool.
  • Agree cleaning, disinfection, water-safety and maintenance responsibilities.
  • Check whether the project requires wall-mounted services or access around the complete pool.
  • Assess delivery access, structural loading, drainage, electrical options and future service access.

This early assessment prevents a common project error: choosing a pool that physically fits the drawing but does not provide enough usable space for care, cleaning or emergency response. [3,7]

Choose the correct pool size

Active Birth Pools are available in three sizes. The choice should be based on the room, the intended model of care and the working access required around the pool, rather than on capacity alone. [5]

Princess II and Princess 360

The Princess is the compact model in the range. It is intended for rooms where space is limited but a purpose-designed hospital pool is still required. Its extra-wide rim and single-step access arrangement are designed to support a controlled sit-and-swivel entry rather than requiring the mother to climb a multi-step unit. [8,9]

The Princess may be the appropriate starting point for smaller delivery rooms, refurbishments and projects where every centimetre must be carefully planned. The current model drawings should be used to confirm the footprint, working clearances and service positions.

Venus II and Venus 360

The Venus is the mid-size model. First developed in the late 1980s as a specially designed hospital water birth pool, it provides generous internal space while requiring less room than the largest Active model. Its dimensions and depth are intended to facilitate free movement and maximise the benefits of immersion during labour. [10]

The Venus is often suited to hospitals seeking a balance between internal space, room efficiency and access for staff.

Active II and Active 360

The Active is the largest model in the range. It is designed for spacious maternity rooms where maximum freedom of movement, internal support and working access are priorities. The larger footprint must be planned with adequate clearances, delivery access and structural loading in mind. [11]

Use current drawings – Dimensions, capacities, weights, service positions and installation details vary by model and may be updated. Always design from the current data sheet and issued installation information for the selected pool. [4]

Decide between wall-mounted and 360° access

Every Active Birth Pools size is available in two configurations. The choice affects the room layout, service positions and the number of sides from which staff can work. [5]

Wall-mounted II models

Wall-mounted models are designed for rooms where the pool is positioned against a service wall. They can make efficient use of space and allow water and waste services to be coordinated at the rear or side of the pool. The design must preserve access to inspection panels, traps, valves and fixing points.

Freestanding 360° models

Freestanding models are intended for rooms where movement and care around the complete pool are required. The Active Birth Pools Water Column carries taps, spout and associated services away from the pool rim, helping to keep the principal working edge clear. The Water Column and floor service positions must be set out from the current model drawings before floors and finishes are completed. [6,11]

A 360° configuration does not automatically make a room workable. The project must still provide practical staff clearances, bed or trolley access and unobstructed routes around the pool.

Examine the material and construction

Hospital water birth pools are exposed to repeated filling, emptying, cleaning and disinfection. The material must therefore be assessed for durability, structural stability, surface performance, heat retention, cleanability and repairability.

Active Birth Pools are made from Ficore® composite, a highly specialised material developed for the demands of professional maternity use. Active Birth Pools states that Ficore® is stronger and harder than conventional materials, provides good heat retention, and withstands intensive hospital use and repeated disinfection. [12,13]

  • Look for a seamless, non-porous surface that can be cleaned and disinfected consistently.
  • Confirm that the surface and structure are designed for prolonged institutional use, not occasional domestic use.
  • Ask how the material responds to approved hospital cleaning agents and whether surface damage can be professionally repaired.
  • Consider thermal stability and heat retention, which influence comfort and the management of pool water during labour.
  • Check the structural warranty and exactly what it covers.

Active Birth Pools manufactured from Ficore® carry a lifetime warranty against structural failure, loss of rigidity, leakage and surface breakdown, subject to the published terms and conditions. [14]

Look beyond the outline of the pool

Two pools with similar external dimensions can perform very differently in practice. The shape of the interior, the rim, hand supports, seats and the position of fittings determine how easily the mother can move and how closely the midwife can work.

Freedom of movement for the mother

Warm-water immersion is most useful when the mother can change position freely and use the water to support active labour. The pool should provide adequate depth and internal space without forcing a single posture. Integrated support features should assist movement without creating hard projections or obstacles. [1,15]

A broad, rounded working rim

The rim should be comfortable for the mother to hold or sit on and should allow a midwife to get close without leaning across unnecessary metalwork. Active Birth Pools use broad bull-nosed rims and recessed external panels to improve access and reduce obstruction. [2,16]

Recessed handgrips and internal support

Recessed handgrips provide support without adding surface-mounted rails that can obstruct care or complicate cleaning. Internal seats and support areas can help the mother rest, change position and move in stages when leaving the water. [2,7]

Assess entry and exit before purchase

Entry and exit should be considered as a manual-handling and falls-prevention issue, not an accessory decision made after the pool has been ordered. Multi-step arrangements can require the mother to climb in wet conditions and may encourage staff to take her weight.

Active Birth Pools promote a sit-and-swivel method in which the mother sits on the broad rim and turns into the pool while maintaining stable points of contact. A simple low step may be used where required by local assessment. This approach is intended to reduce climbing and minimise the need for a midwife to physically support the mother’s weight. [9,17]

  • Confirm the rim is wide and strong enough to be used as the principal sitting surface for entry and exit.
  • Assess the proposed step for height, stability, cleanability and trip risk.
  • Leave enough room for staff to assist without twisting, overreaching or standing in restricted gaps.
  • Include entry and exit in the hospital’s local manual-handling assessment and staff training.

Protect midwives through ergonomic design

Midwives use the pool repeatedly over many years. A pool that appears attractive but forces prolonged bending, twisting, kneeling or reaching can create avoidable occupational risks. The choice of pool and its position in the room should therefore be assessed from the actual working positions used during labour, birth, observation and cleaning. [7,16]

Active Birth Pools’ ergonomic approach developed from work undertaken with ergonomist Sue Hignett in the 1990s. The resulting design principles include recessed panels, broad rims and clear working edges intended to help midwives get closer to the mother and maintain better posture. [16]

Procurement question
Can midwives reach the mother from the positions in which care will actually be provided, without fixed taps, rails, cabinetry or narrow gaps forcing them to lean or twist?

Plan for foreseeable emergencies

Emergency evacuation is uncommon, but it is foreseeable and must be considered before the pool is selected. The room should allow a height-adjustable bed or trolley and additional staff to be brought close to the pool. Local procedures should define how help is called, how the mother is supported and whether a portable hoist is required. [7,18]

Active Birth Pools incorporate internal support seats and broad rim surfaces that can assist staged movement from the water to a seat, from the seat to the rim, and from the rim to a bed or trolley. The pools are also designed to be compatible with a portable hoist where the hospital’s manual-handling advisers require one. [18]

These design features support emergency planning but do not replace local risk assessment, training, simulation and clinical judgement.

Assess infection-control and water-safety design

Infection prevention is influenced by the pool material, surface finish, drainage, plumbing and the accessibility of every component that must be cleaned or maintained. A hospital pool should be designed to avoid unnecessary water-retaining systems and inaccessible fittings. [19,20]

  • Choose a seamless, non-porous pool surface that can withstand the hospital’s approved cleaning and disinfection procedure.
  • Use a direct water supply with appropriate thermostatic control and the minimum practicable pipework, subject to local regulations and water-safety policy.
  • Avoid integral recirculation, pumped heating, air jets and other systems that can retain water and are difficult to inspect and disinfect.
  • Avoid overflow arrangements and unnecessary surface-mounted fittings that can create inaccessible contamination points or obstruct the working rim.
  • Ensure plugs, strainers and drainage components can be removed, inspected, cleaned and disinfected.
  • Confirm that service panels, valves, traps and joints will remain accessible after the room is complete.

Active Birth Pools cleaning guidance specifies a two-stage process: cleaning first, followed by disinfection. Pool selection and room planning should make that procedure practical between every use. [20]

Check installation requirements before ordering

The pool should be selected before the final water, waste, floor and electrical design is completed. Current model drawings must be used to coordinate the actual footprint, fixing points, service positions and access requirements. [3,4]

  • Verify the floor structure for the combined load of the pool, water and user.
  • Provide a completed, level, stable and cleanable floor suitable for the model-specific fixing system.
  • Coordinate through-wall or through-floor waste routes and retain access to traps and joints.
  • Confirm filling flow rate, thermostatic control, backflow protection, isolation and flushing arrangements with the competent project team.
  • Protect working clearances and access panels from later encroachment by cabinets, pipe boxes or equipment.
  • Check crate dimensions, doors, corridors, lifts, turning spaces and the complete delivery route.
  • Coordinate any approved lighting or sound options with the electrical designer before finishes are completed.

Compare whole-life value, not simply purchase price

The lowest initial quotation is not necessarily the lowest-cost option over the life of a maternity unit. A hospital should consider expected service life, warranty, cleaning time, maintenance, repairability, reliability, energy and water use, replacement frequency, staff usability and the availability of technical support. [21,22]

Active Birth Pools states that Ficore® pools are engineered to last for decades and are guaranteed for life. A long service life can reduce the financial and environmental cost associated with repeated replacement, while a durable and repairable surface can help maintain the pool’s performance and appearance. [6,14,22]

  • Ask for the expected service life and evidence from comparable hospital installations.
  • Review the warranty terms, exclusions and the supplier’s ability to provide support over time.
  • Consider whether the design reduces cleaning complexity and avoids proprietary water-retaining systems.
  • Assess how the pool supports staff posture, maternal entry and emergency planning, as these factors affect operational value as well as safety.
  • Confirm that current drawings, data sheets, installation information and replacement components are readily available.

Questions to ask every water birth pool supplier

  • Was the pool designed specifically for professional maternity and hospital use?
  • Which exact model and configuration best suits our room and intended model of care?
  • What material is the pool made from, and how does it perform under repeated hospital cleaning and disinfection?
  • Is the construction seamless and non-porous?
  • Does the pool contain pumps, jets, recirculation, integral heating or inaccessible pipework?
  • How are the plug, drain and service components inspected, cleaned and maintained?
  • Can the mother enter and leave without climbing a multi-step unit or requiring a midwife to take her weight?
  • Can midwives work close to the mother from the required positions without excessive bending, twisting or reaching?
  • How does the design support foreseeable emergency evacuation and portable-hoist access?
  • What are the filled weight, capacity, delivery dimensions, fixing points and service requirements?
  • What is the expected service life, and what does the warranty cover?
  • Can the supplier provide current drawings, data sheets, installation guidance and project support?
  • Can the supplier provide references from hospitals using the same or comparable models?

Water Birth Pool Safety Risks: What Hospitals Should Avoid Before Buying

Purchasing a water birth pool is a significant responsibility.

The decision should never be based on appearance, price or catalogue features alone. In a maternity unit, a birth pool becomes part of the clinical environment, the cleaning regime, the hot and cold water system, and the manual-handling strategy. Every fitting, outlet, seal, drain, hose and access point can either reduce risk or introduce unnecessary complexity.

Some features look reassuring at first glance. A rim-mounted tap may appear convenient. A swan-neck spout may look elegant. A door may seem to make access easier. A built-in heating or recirculating system may sound technically advanced. But in a healthcare setting, the first question should always be: does this feature make the pool safer, easier to clean and easier to manage – or does it create another risk point?

This guide explains the design features hospitals, birth centres, architects, procurement teams and maternity staff should question before specifying a water birth pool.

Safety checklist: features to question before buying

Feature Main concern Safer design principle
Rim-mounted taps, spouts and showers Extra joints, crevices and possible backflow exposure close to pool water. Keep water services separate from the pool; use wall, IPS panel or water-column installation with suitable backflow protection.
Surface-mounted hand grips and metalwork Fixings, plates and gaps can trap moisture and make cleaning harder; protrusions may obstruct movement. Use integrated or securely bonded details with smooth, accessible surfaces.
Swan-neck taps Retained water and complex outlet geometry can increase microbial risk. Specify low-risk outlets selected by estates and water-safety teams.
Recirculating, jetted or pumped systems Warm, moving water, pipework and aerosols can support and spread waterborne organisms. Fill for use, empty after use and clean under protocol; avoid recirculation for labour and birth.
Integral plumbing, filters and built-in heaters Hidden pipework and components can be difficult to inspect, disinfect and monitor. Keep services accessible, maintainable and within the hospital water-safety plan.
Handheld showers that can enter the pool Potential contamination and backflow risk if the hose/head can be submerged. Use compliant, removable or restrained arrangements approved by estates/water-safety teams.
Overflow drains, door seals and unnecessary seals Wet seals and hidden recesses can become persistent dirt and moisture traps. Use simple, seamless construction with removable, cleanable drainage components.

Why design matters in a maternity setting

Healthcare guidance is clear that infection prevention should be designed into healthcare environments from the beginning. HBN 00-09 states that a building’s design can help infection prevention and control by providing an environment that is easy to clean and maintain. [1]

That principle applies directly to water birth pools. A pool with fewer joints, fewer ledges, fewer penetrations and fewer unnecessary fittings is usually easier to clean, inspect, dry and return safely to use. By contrast, complex fittings can create small spaces where moisture, organic matter and microorganisms can remain after cleaning.

NICE recommends that baths and birthing pools are kept clean using a protocol agreed with the local microbiology department or infection-control guidance, and in accordance with the manufacturer’s guidelines. [2] A good pool design should make that requirement practical in a busy maternity unit, not difficult to achieve.

This bath shows a variety of unsafe fittings and systems that are often found on water birth pools.
Note the overflow drain, recirculating water system, swan neck tap, integral shower, rim mounted plumbing and controls.

1. Rim-mounted taps, spouts and showers

Rim-mounted taps, spouts and showers should be treated with caution in a hospital water birth setting.

The issue is not only whether the fitting looks sealed. Bacteria and biofilm are microscopic. Small gaps around a base plate, tap hole, washer or fixing can retain moisture and residue. These areas can be awkward to reach during routine cleaning and inspection.

There is also a water-safety consideration. Water Regs UK notes that all bathroom water fittings need appropriate backflow protection rated to the highest downstream contamination risk, and that showers in healthcare premises can be treated as Fluid Category 5 risk. [3] In a water birth room, the estates team and water-safety group should therefore be closely involved in the specification of taps, showers, hoses, backflow protection and outlet positioning.

Safer principle: keep taps and spouts off the pool rim. Fill the pool from wall-mounted services, an IPS panel or a purpose-designed water column. This keeps the pool simpler, leaves fewer holes and fittings in the shell, and allows water services to be managed as part of the hospital’s water system rather than as part of the pool itself.

2. Surface-mounted hand grips and internal metalwork

Handholds are important. Mothers need secure support when entering, leaving and changing position in the pool. The question is how that support is provided.

Surface-mounted hand grips, rails and metal plates can introduce fixing points, edges and narrow gaps. If they sit inside the pool or on the rim, they may come into direct contact with pool water and can make cleaning more complicated. They can also create protrusions that interfere with movement, comfort and midwife access.

In a clinical setting, cleanability matters as much as strength. A well-designed support feature should feel secure, be easy to wipe, avoid exposed fixings and avoid unnecessary ledges or dirt traps.

Active Birth Pools address this by using integrated, bonded hand grips designed to provide stable support while keeping the internal pool environment smooth, accessible and cleanable.

3. Swan-neck taps and retained water

Swan-neck taps may look attractive, but they are not ideal for a water birth environment. Their shape can retain water after use, and retained water can contribute to microbial biofilm formation if outlets are not designed, flushed and maintained correctly.

HTM 04-01 gives healthcare premises guidance on the design, maintenance and operation of hot and cold water systems, including control and management of risks from Legionella, Pseudomonas aeruginosa and other waterborne pathogens. [4]

The lesson for birth-pool specification is simple: avoid decorative or domestic-style outlets where a lower-risk, healthcare-appropriate outlet would be easier to manage. Outlet choice should be made with the hospital’s estates, infection-control and water-safety teams.

4. Recirculating, jetted and pumped water systems

Recirculating systems, spa-style jets, pumped heating systems and whirlpool features have no place in a modern hospital water birth pool.

They add pipework, pumps, cavities, valves and hidden wet areas. Once microorganisms enter these systems, they can be difficult to remove. Recirculating or aerating systems can also generate aerosols when bubbles break or water is agitated, increasing the potential route of exposure.

NHS England issued a patient safety alert about heated birthing pools with built-in heaters and recirculation pumps filled in advance of labour. [5] Public Health England later reported that, after a recall of heated home birthing pools, 4 of 6 tested pools were positive for Legionella and 3 also tested positive for other potentially harmful organisms including Pseudomonas aeruginosa. [6]

This does not mean fixed hospital birthing pools are unsafe. The concern is specifically with unnecessary heating, storage, recirculation and hidden systems. The safer approach is to fill the pool for use, monitor water temperature during labour, empty the pool after use and clean it under local protocol and manufacturer guidance.

5. Integral plumbing and hidden services

Integral plumbing systems can look neat, but hidden pipework is rarely an advantage in a healthcare environment.

Flexible hoses, internal pipes, pumps, filters, valves, heaters and concealed spaces can be difficult to inspect, disinfect, maintain and monitor. Stagnant water in dead legs or rarely used sections of pipework is a recognised water-safety concern. The HSE notes that hot and cold water systems can present a foreseeable risk of exposure to Legionella, and that understanding the water system and its parts – including dead legs, TMVs and outlets – is necessary for risk assessment. [7]

For hospitals, the safer design principle is separation. The birth pool should be a fixed, cleanable sanitary-ware product. The water services should be specified, installed, accessed and maintained by the hospital’s estates team as part of the wider water-safety plan.

6. Handheld showers and hose management

Handheld showers are a common source of confusion. They are useful for cleaning the pool after use, but they can create a risk if the hose or handset can enter the pool water during use.

Water Regs UK explains that shower installations must have appropriate backflow protection and that, in high-risk settings such as healthcare premises, showers may be classed as Fluid Category 5 risk. Hose handsets capable of reaching contaminated water sources require suitable Fluid Category 5 backflow-prevention arrangements unless the hose is permanently restrained or shortened to maintain an adequate gap. [3]

For water birth rooms, the safe approach is to prevent the shower hose or head from entering the pool during labour and birth, and to ensure the design is approved by estates and the water-safety group. A removable cleaning hose may be acceptable where it is detached when the pool is in use and used only after the pool has been emptied for cleaning, subject to local approval.

7. Built-in filters and disinfection devices

Filters and disinfection devices should not be used to justify a poor basic design.

If a pool relies on filters to compensate for built-in plumbing, recirculation, hidden pipework or complex wet components, the underlying problem remains. Filters require maintenance, monitoring and replacement. They can reduce risk only when they are correctly specified and managed within a formal water-safety system.

The better design principle is to remove avoidable risk at source: no recirculation, no hidden wet systems, no unnecessary pipework inside the pool and no complex internal fittings that are difficult to access.

8. Overflow drains and hidden wet recesses

Overflow drains are another feature borrowed from baths and spa products that should be questioned in water birth pools.

An overflow adds hidden surfaces, internal channels and wet recesses. These areas can be difficult to access during routine cleaning and can retain moisture between uses. If a feature cannot be reliably cleaned, inspected and dried, it should not be built into a healthcare birth pool unless there is a clear, justified reason.

The safer design principle is a simple, purpose-designed drainage system with components that can be removed, cleaned, disinfected, rinsed, dried and checked in accordance with local policy.

9. Doors, seals and access panels

A door in a water birth pool may appear helpful, but it introduces a major design compromise.

Doors require seals, hinges, locking mechanisms and joints. These features are exposed to warm water, organic matter and repeated cleaning chemicals. Any seal or hinge line can become a moisture trap. In an emergency, a door may also complicate rather than simplify evacuation, because staff still need space, technique, equipment and coordinated manual handling.

Access should be solved through the pool’s height, internal shape, external step, handholds, midwife access and local emergency procedures – not by introducing a door and seal into the pool shell.

10. Domestic styling in a clinical environment

A maternity pool should not be specified as though it were a domestic bath, spa bath or wellness product.

In hospitals, design priorities are different. The pool must support infection prevention, water-safety governance, manual handling, cleaning, inspection, maintenance and repeated clinical use. A domestic-style feature may look reassuring in a brochure while creating avoidable work for maternity, cleaning and estates teams.

When assessing a pool, procurement teams should ask: Can every surface be reached? Can every component be inspected? Can the pool be cleaned quickly and consistently between births? Are water outlets separate and maintainable? Are there any hidden wet areas? Does each fitting justify its risk?

What safer birth-pool design looks like

A safer water birth pool is not over-engineered. It is simple, strong, cleanable and purpose-designed for maternity use.

Active Birth Pools are designed around this principle. They use smooth Ficore® surfaces, seamless one-piece construction, integrated hand grips, minimal fittings, purpose-designed drainage and water services kept separate from the pool rim. Freestanding installations can be supported by a dedicated water column so that taps, spout, shower and support rail remain separate from the pool itself.

This approach supports the same aim described in healthcare guidance: make the environment easier to clean, easier to maintain and easier to manage safely.

Buyer questions before specifying a water birth pool

Before purchasing a water birth pool, ask the supplier:

  1. Are there any taps, spouts, showers or controls mounted on the pool rim?
  2. Are any hand grips, rails or metal fittings bolted onto the internal surface?
  3. Does the pool include any recirculation, jets, pumps, heaters or hidden pipework?
  4. Can every wet surface be cleaned, disinfected, rinsed, dried and inspected?
  5. Are there any overflows, doors, seals or inaccessible cavities?
  6. Is the pool filled for use and emptied after use, rather than maintained warm in advance?
  7. Has the installation been reviewed by estates, infection-control and water-safety teams?
  8. Does the manufacturer provide clear cleaning and care guidance?

Conclusion: remove avoidable risk at source

No product can replace local clinical judgement, infection-control procedures, estates management or water-safety governance.

But good design can make those responsibilities easier to fulfil.

A hospital water birth pool should not be a spa product adapted for maternity use. It should be a fixed, purpose-designed sanitary-ware product that supports safe water use, effective cleaning, practical midwifery and maternal movement.

The safest features are often the ones that are not there: no rim-mounted taps, no jets, no recirculation, no hidden plumbing, no overflows, no doors and no unnecessary surface-mounted metalwork.

In maternity environments, simplicity is not basic. Simplicity is safer.

Designed to Optimise Safety, Reduce Risk and Support Safer Birthing Environments

Safety begins with design

When hospitals create or refurbish water birth facilities, safety must be designed in from the outset.

A birth pool is not simply a vessel for warm water. In a maternity unit it becomes part of the clinical environment, the water system, the cleaning regime and the manual-handling strategy. Every surface, fitting, outlet and access point has implications for infection prevention, water safety, mother safety and midwife safety.

Warm, moist environments can support the growth of waterborne organisms if they are not properly controlled. Healthcare guidance recognises the need to manage risks from pathogens such as Legionella and Pseudomonas aeruginosa through appropriate design, maintenance, cleaning, monitoring and local water-safety procedures. [1]

Active Birth Pools have been developed with these responsibilities in mind.

Our design philosophy is simple: remove avoidable risk at source wherever possible, make cleaning easier and more effective, and support hospitals in meeting their local infection-control, water-safety and maternity-care protocols.

Superior material equals superior safety

Active Birth Pools are fabricated from Ficore®, our proprietary composite material.

Ficore® gives our pools exceptional strength, durability and surface integrity. Its hard, smooth, non-porous finish is designed to withstand the demands of repeated clinical use and routine disinfection, while helping staff clean the pool thoroughly between births.

In a hospital environment, surface quality matters. Scratched, porous, jointed or damaged surfaces can make effective cleaning more difficult. By contrast, a smooth, seamless surface helps reduce places where organic matter, moisture and microorganisms can collect.

The result is a birth pool that supports infection-control practice by design, not by afterthought.

Seamless one-piece construction

Active Birth Pools are manufactured as seamless, one-piece structures.

This is an important safety feature. Joints, seams, cracks, ledges and surface-mounted fittings can create dirt traps and areas where moisture can remain after cleaning. Our one-piece construction minimises these vulnerable areas and helps staff achieve a consistent cleaning outcome.

NICE guidance states that baths and birthing pools should be kept clean using a protocol agreed with the local microbiology department or infection-control guidance, and in accordance with the manufacturer’s guidelines. [2]

Our pools are designed to make that requirement easier to fulfil.

Flowing contours that improve cleanability

Ficore® allows us to manufacture pools with flowing, organic shapes rather than sharp internal angles.

The smooth internal form helps water drain efficiently, supports thorough wiping, and reduces awkward areas that are difficult for staff to reach. This matters because cleaning must be practical, repeatable and achievable in a busy maternity setting.

Good infection control is not only about which disinfectant is used. It is also about whether the product’s design allows staff to clean every surface properly, quickly and consistently.

Minimal fittings, fewer risk points

Every fitting on a birth pool should justify its presence.

Active Birth Pools use the minimum number of surface-mounted components. This reduces complexity, improves cleanability and limits areas where water, residue or contamination could accumulate.

Our design approach is aligned with a basic infection-prevention principle: the fewer unnecessary joints, penetrations and ledges there are, the fewer areas staff need to manage during cleaning and inspection.

Integrated hand grips

Our stainless-steel hand grips are bonded directly into the structure of the pool.

They are not simply bolted onto the rim. The grip is sealed into the fabric of the pool, creating a secure, stable and easy-to-clean detail with no loose movement and no exposed fixing points around the rim.

This gives mothers firm support when changing position, entering or leaving the pool, while also avoiding the hygiene issues associated with unnecessary surface-mounted metalwork.

Purpose-designed drainage

The drainage system is a critical part of birth pool safety.

Active Birth Pools are fitted with a purpose-designed drainage assembly manufactured to high standards. The waste sits in a recess and is securely sealed to help create a watertight, cleanable installation.

The plug can be removed for cleaning and disinfection between births, supporting local decontamination protocols. Removable components make inspection and cleaning easier and help staff follow a consistent post-use procedure.

Local NHS birth-pool cleaning protocols commonly require removal of debris, cleaning, disinfection, rinsing, drying and documented daily checks. [3]

Our drainage design supports these practical requirements.

Lighting designed to avoid water traps

Where underwater lighting is specified, the fitting is designed to sit flush with the internal wall of the pool.

The stainless-steel bezel is sealed into the pool surface, and the vertical mounting helps prevent water from sitting around the fitting. The control switch is also sealed.

This approach avoids unnecessary protrusions and supports the same design objective used throughout the pool: smooth surfaces, minimal ledges and cleanable details.

Plumbing that’s separate from the pool

We do not recommend mounting taps on the rim of a birth pool.

Taps, spouts and showers should be installed on the wall, on an IPS panel, or on a dedicated water column. This keeps the pool rim clear, reduces fittings on the pool itself and helps separate the hospital water-supply installation from the pool structure.

Healthcare water-safety guidance recognises the importance of design, installation, commissioning, maintenance and operational management of hot and cold water systems in healthcare premises. [1]

Separating the plumbing from the pool supports this principle by allowing estates teams to specify, access, maintain and manage water outlets as part of the hospital’s water-safety system.

Thermostatic mixing valves and scald protection

Birth-pool filling water must be controlled safely.

Thermostatic mixing valves are used in healthcare settings to reduce scalding risk, but they must be correctly specified, installed, maintained and included within the organisation’s water-safety procedures. [4]

We recommend suitable thermostatically controlled bath or bath/shower mixers, specified by the hospital’s estates team in accordance with local water-safety policy and current healthcare guidance.

NICE also recommends that, when women are labouring in water, both the woman’s temperature and the water temperature are monitored hourly, and that the water temperature should not be above 37.5°C. [2]

Warning: Recirculating water systems

Waterborne infection risk increases when warm water is stored, recirculated or maintained for prolonged periods.

NHS England issued a patient safety alert on heated birthing pools that incorporate both a pump and heater and are filled in advance of labour. The alert required organisations to ensure hospital birthing pools are covered by Legionella management control policies and procedures. [5]

Public Health England also advised that fixed birthing pools in NHS units are considered safe when they are subject to stringent infection-control procedures, and distinguished them from heated pools filled in advance and maintained warm by heater and circulation pump. [6]

Active Birth Pools are designed as fixed, hospital-grade sanitary-ware products. They are filled for use, emptied after use and cleaned in accordance with local protocols and manufacturer guidance. They do not rely on recirculating heated water.

Purpose designed Water Column for freestanding installations

Freestanding birth pools are increasingly popular because they allow more flexible room layouts and better all-round access for mothers and midwives.

However, freestanding installations still need safe, accessible and maintainable plumbing.

To solve this, we developed the Active Birth Pools Water Column: a dedicated solution that keeps taps, spout, shower and support rail separate from the pool itself.

The Water Column provides the practical advantages of a freestanding pool while allowing the water services to remain accessible, controlled and cleanly detailed. It also keeps the pool rim free from tap holes and unnecessary fittings.

Supporting hospital water-safety governance

Healthcare premises are expected to manage water safety through appropriate governance, risk assessment, operational control and monitoring.

HTM 04-01 provides guidance for healthcare management, water safety groups, design engineers, estate managers, contractors and supply-chain businesses. It covers the legal requirements, design applications, maintenance and operation of hot and cold water systems in healthcare premises, and gives guidance on managing risks from Legionella, Pseudomonas aeruginosa and other waterborne pathogens. [1]

Our role is to provide birth pools whose design supports those duties.

Active Birth Pools help hospitals by providing:

  • seamless, one-piece construction
  • smooth, hard, cleanable surfaces
  • minimal surface-mounted fittings
  • integrated hand grips
  • removable, cleanable drainage components
  • plumbing kept off the pool rim
  • compatibility with wall-mounted or water-column water services
  • practical manufacturer guidance for cleaning and care

Supporting maternity care and informed choice

Water immersion is an established option in maternity care.

NICE recommends offering women the opportunity to labour in water for pain relief. NICE also now advises that birth in water may be considered, with balanced discussion of the evidence so women can make an informed choice. [2]

This makes the quality and safety of the birth-pool environment especially important.

A well-designed pool should support the mother’s freedom of movement, comfort and sense of privacy. It should also support midwives by providing good visibility, access, stable handholds, practical cleaning and safe working space around the pool.

Safety by design

No product can replace local clinical judgement, infection-control protocols, estates management or water-safety governance.

But good design can make those responsibilities easier to fulfil.

Active Birth Pools are designed to reduce avoidable risk, support effective cleaning, improve water-safety management and create safer, calmer, more practical birthing environments.

That is the difference between a pool that simply holds water and a birth pool designed specifically for modern maternity care.

Internal Design Features That Make Active Birth Pools Safer, More Supportive and Easier to Use

Why the inside of a birth pool matters

A water birth pool is not simply a container for warm water. In a maternity setting, it becomes part of the birth environment, part of the mother’s support system and part of the midwife’s working space. Its internal shape, rim, seats, handholds, water channel and surfaces all influence how freely a woman can move, how safely she can enter and leave the pool, how comfortably she can rest between contractions, and how effectively midwives can monitor, assist and respond when needed.

This is why the internal design of an Active Birth Pool has been developed around a central principle: the pool should actively support physiological labour and birth while reducing avoidable risks for mothers, babies, midwives and hospitals.

Every contour has a purpose. Every support point has a function. Every surface is designed to be smooth, hygienic and easy to clean. The result is a pool that enables mothers to move instinctively, adopt upright and forward-leaning positions, rest when they need to, and remain supported throughout labour and birth.

Four internal features are especially important to this design philosophy: the rim-level safety seat, the labour support seat, the recessed handrails and the keyhole-shaped water channel built into the back of the rim. Together, they transform the pool from a passive vessel into an ergonomic, clinically practical and user-centred birth environment.

Designed for active birth, not passive immersion

The name Active Birth Pools reflects a specific design intention. Labour in water is most effective when the mother is able to move, change position and respond instinctively to the sensations of labour. A well-designed birth pool should encourage mobility rather than restrict it.

In practice, this means the internal form of the pool must support a wide range of natural positions: kneeling, squatting, sitting, leaning forward, resting on the rim, holding the handrails, turning, rotating, floating, and moving from one position to another without obstruction. The mother should not feel trapped by the shape of the pool. She should feel held, supported and free.

This is the fundamental difference between a general-purpose bath and a purpose-designed birth pool. A bath is designed for washing and reclining. A birth pool must support movement, buoyancy, upright posture, pelvic mobility, maternal comfort, midwifery access, observation, hygiene, emergency evacuation and repeated clinical use.

Active Birth Pools are designed around these realities. The internal features are not decorative additions. They are built into the structure of the pool to support real use in real maternity settings.

The rim-level safety seat: support, rest, monitoring and emergency evacuation

One of the most distinctive internal features of an Active Birth Pool is the rim-level safety seat. This seat is positioned high in the pool, level with the rim, creating a broad, secure platform that can be used in several important ways.

For the mother, the safety seat provides a comfortable place to lean, pause and recover between contractions. Labour is physically demanding, and women often need to move between activity and rest. The safety seat allows the mother to remain in the water while changing her posture and receiving support. She can lean forward onto the rim, rest her arms, or position herself securely while remaining connected to the warmth and buoyancy of the pool.

This matters because labour is not static. A mother may want to kneel during one contraction, sit back during the next, then lean forward as labour intensifies. The safety seat gives her another supported option without requiring her to leave the water or interrupt the rhythm of labour.

For midwives, the rim-level safety seat is equally important. It creates a practical platform for observation and monitoring without requiring the mother to stand up or climb out of the pool unnecessarily. In many birth pools, routine checks can become awkward because the mother is low in the water and the midwife has limited access. A rim-level seat helps bring the mother into a more accessible position while preserving her comfort, privacy and immersion.

The safety seat also has a critical role in emergency evacuation. Although most water births proceed without incident, every hospital-grade birth pool must be designed with the possibility of urgent assisted evacuation in mind. If a mother becomes faint, exhausted or unable to leave the pool unaided, midwives need safe and practical options. The rim-level safety seat gives staff a secure intermediate platform. Instead of trying to lift a mother directly from the bottom of the pool to the outside, the mother can be guided or assisted onto the seat and then onto the rim for transfer.

This staged movement reduces strain and helps support safer manual handling. It also protects maternal dignity because the pool itself becomes part of the evacuation pathway rather than an obstacle. In this way, the safety seat combines comfort, clinical practicality and risk reduction in one integrated feature.

The labour support seat: supporting physiology and instinctive movement

The labour support seat is another key internal design feature. Its role is different from the rim-level safety seat. Whereas the safety seat is positioned high for rest, monitoring and evacuation, the labour support seat is designed to support the mother lower in the pool during labour and birth.

The labour support seat helps the mother find stable, upright and open positions. In water, buoyancy reduces the effect of gravity on the body, making it easier for women to move and change posture. However, buoyancy alone is not enough. A mother also needs points of contact that allow her to stabilise herself, control her position and use her body effectively during contractions.

The labour support seat gives the mother a secure base from which she can move her pelvis, adjust her angle, lean forward, rotate or rest. This supports the principles of active birth, where the mother is encouraged to remain responsive to her body rather than being fixed in one position.

A well-designed labour support seat should not dominate the pool or restrict movement. It should be there when needed and unobtrusive when not in use. It should support rather than confine. The mother should be able to use it as a seat, a brace, a transition point or a place to rest briefly before moving again.

This kind of design recognises that labour is dynamic. The most useful support is not rigid prescription but flexible assistance. The labour support seat gives mothers options, and options are central to comfort, confidence and physiological labour.

For midwives, the labour support seat can also assist with care. It helps position the mother in ways that may make observation easier, while still allowing her to remain in the water. It can support safe assisted movement in the pool and contribute to a calmer, more controlled environment.

Recessed handrails: secure support without obstruction

Hand support is essential in a birth pool. During labour, women instinctively reach for something to hold, pull against, lean on or use as a stabilising point. A good handhold can help a mother move from sitting to kneeling, brace during a contraction, rotate her body, lower herself into the water or rise from the pool.

However, handrails can also create problems if they are poorly designed. Surface-mounted metal rails may protrude into the pool, obstruct movement, create impact risks, interfere with cleaning and provide areas where contamination can collect. In a clinical environment, these issues are not minor. They affect safety, hygiene and usability.

Active Birth Pools address this by setting the stainless steel handrails into recesses in the rim and bonding them into the fabric of the pool. This design achieves several things at once.

First, it gives mothers a strong, reliable handhold exactly where they need it. The handrails are positioned so they can be used naturally during movement around the pool. Mothers can grip them while entering, leaving, turning, leaning, kneeling or changing position.

Second, the recessed design protects mothers from injury. Because the handrails are set into the rim rather than protruding into the pool, they are far less likely to be knocked, bumped or caught during movement. This is especially important in labour, when a woman may move suddenly or instinctively and may not be carefully watching where every fitting is positioned.

Third, the design supports freedom of movement. The interior remains smooth and uncluttered, allowing the mother to move around the pool without negotiating exposed metalwork. In a birth pool, open usable space is vital. Anything that obstructs movement can reduce the mother’s ability to respond naturally to labour.

Fourth, recessed bonded handrails improve hygiene. In any maternity unit, infection prevention is a core priority. Fittings that sit proud of the surface can create edges, joins and dirt traps. Bonding the handrails into the pool and integrating them into the design helps reduce areas where microorganisms may collect and makes the pool easier to clean between uses.

This is a good example of the Active Birth Pools design approach: one feature solving several problems at once. The handrails provide support, reduce impact risk, preserve internal space and improve cleanability.

The keyhole-shaped water channel: protecting mothers from protruding spouts

One of the most innovative design features is the keyhole-shaped water channel built into the back of the rim. At first glance, it may appear to be a simple detail. In practice, it is a major safety and usability improvement.

In many birth pool installations, the water supply is delivered through taps or spouts positioned near the pool. If these protrude into the mother’s movement area, they create a risk of impact, particularly to the head. During labour, women may lean back, turn quickly, float, kneel, rise or move unpredictably. A protruding spout in the wrong place can become a hazard.

Active Birth Pools respond to this by incorporating a distinctive keyhole-shaped channel into the back rim of the pool. The channel works with wall-mounted taps and short spouts positioned so that the mother cannot come into contact with them. In other words, the water delivery system is accommodated without placing intrusive metalwork in the mother’s path.

This protects the mother from hitting her head on the spout and keeps the back of the pool open and usable. She can lean against the back of the pool, hold the recessed handgrips, use the rounded rim for support and move freely without being obstructed by plumbing.

The keyhole channel also contributes to a cleaner, simpler internal environment. By avoiding rim-mounted taps and unnecessary fittings, the pool reduces clutter around the rim. This benefits mothers, who need freedom of movement, and midwives, who need clear access. It also supports infection control by reducing the number of surface-mounted fittings where bacteria may collect.

The importance of this detail should not be underestimated. Good healthcare design often consists of removing risks before they occur. The keyhole-shaped water channel is a preventative design solution. It does not ask mothers or midwives to work around a hazard. It removes the hazard from the usable space.

The extra-wide rounded rim: the feature that links everything together

Although the article focuses on the internal features, the rim deserves special attention because it connects many of them. The extra-wide rounded rim is one of the most important support surfaces in the pool.

For mothers, the rim provides a place to lean forward, rest the arms, brace the body and maintain upright positions. Forward-leaning positions are widely used during labour because they can help the mother feel grounded, supported and in control. The rim must therefore be wide enough, smooth enough and comfortable enough to be used repeatedly and for extended periods.

A narrow or sharp rim is not adequate for this purpose. It may dig into the arms, restrict comfort or discourage the mother from using the position she naturally wants. A broad bullnose-shaped rim, by contrast, provides a tactile, supportive surface. It allows the mother to rest on her forearms, lean into contractions and move around the edge of the pool with confidence.

For midwives and partners, the rim also provides a practical support surface. They may lean on it while attending the mother, offering reassurance, monitoring progress or providing physical support. In this sense, the rim is not just a boundary. It is an active working surface.

The rim also supports entry and exit. Combined with the step unit and handholds, it helps mothers move safely into and out of the pool. This is especially important because wet surfaces, fatigue and advanced labour can all increase the need for stable support.

An uncluttered interior supports safer movement

A recurring theme in Active Birth Pools design is the absence of unnecessary surface-mounted metalwork. This is not only an aesthetic choice. It is a safety and hygiene decision.

The more fittings that are attached to the pool surface, the more potential obstruction points are created. Protruding taps, exposed rails, controls and other fittings can interfere with movement, create impact risks and complicate cleaning. They can also make the pool feel visually and physically cluttered.

By integrating support features into the structure of the pool, Active Birth Pools create a smoother, simpler and more intuitive environment. The mother can move around the pool without constantly negotiating obstacles. Midwives can access the mother more easily. Cleaning is more straightforward. The pool looks and feels calmer.

This is especially important in labour, where the environment can influence how safe, private and confident a woman feels. A clear, uncluttered pool supports the instinctive nature of active birth. The design fades into the background, allowing the mother to focus on her body, her baby and her support team.

Conclusion: purposeful design that supports safer birth

The internal design of an Active Birth Pool is the result of practical experience, careful observation and a clear understanding of what mothers and midwives need during water labour and birth. Each feature has been developed to serve a real purpose: to support movement, improve comfort, reduce hazards, assist clinical care and make the pool easier to use safely.

The rim-level safety seat provides a secure place for rest, monitoring and assisted evacuation. The labour support seat gives mothers another stable position from which to move, lean, rotate and respond instinctively to labour. The recessed handrails offer dependable support without creating obstructions or unnecessary cleaning challenges. The keyhole-shaped water channel keeps water delivery safely out of the mother’s movement space, helping to prevent contact with protruding spouts.

Together with the extra-wide rounded rim and uncluttered interior, these features create a birth pool that is not simply comfortable, but intelligently designed around the realities of maternity care.

For mothers, this means greater freedom, confidence and physical support. For midwives, it means better access, safer working conditions and more practical options when assistance is needed. For hospitals and birth centres, it means a purpose-designed pool that supports safety, hygiene and repeated clinical use.

Good birth pool design should feel natural in use, but that simplicity depends on careful detail. In Active Birth Pools, the internal features work quietly together to create a safer, calmer and more supportive environment for labour and birth.

Superior Material Results in Superior Safety, Value and Performance

Why Ficore® Composite Is the Better Material for Hospital Water Birth Pools

Why the material matters

A water birth pool is not simply a large bath. In a maternity unit it becomes part of the clinical environment, part of the mother’s support system and part of the midwife’s working space. The material it is made from affects how the pool feels, how well it retains heat, how easy it is to clean, how safely it performs under pressure and how long it remains fit for hospital use.

That is why Active Birth Pools are made from Ficore® composite rather than ordinary acrylic or fibreglass. Ficore is a proprietary solid composite of eight materials that are chemically fused during manufacture and heat-cured at high temperature. It is not laminated or bonded, so it cannot delaminate or come apart like layered materials can. [1][2]

For a hospital water birth pool, this is more than a technical detail. It is the foundation of the pool’s strength, hygiene, comfort, repairability and whole-life value.

Developed to overcome the limits of ordinary bath materials

Acrylic and fibreglass are common in domestic bathroom products because they are relatively light, economical and easy to form. Those advantages matter in ordinary bathing, but a water birth pool has to cope with far more demanding conditions.

A birth pool is filled and emptied repeatedly. It holds hundreds of litres of warm water. It has to support the mother’s body weight and movement, midwifery contact, frequent cleaning, disinfection, inspection and, where necessary, assisted evacuation. Its surface must remain smooth, warm, stable, non-porous and cleanable after years of use.

Ficore was developed specifically to address the weaknesses of conventional bath materials while preserving their useful qualities. It is strong but comparatively light, rigid without a supporting chassis, highly resistant to impact and chemicals, warm to the touch, fully repairable and capable of being moulded into precise ergonomic forms. [2]

Solid composite construction, not laminate

One of Ficore’s most important advantages is that it is a solid composite rather than a laminated or bonded construction. The eight constituent materials are chemically fused and heat-cured into a unified structure. This means the material cannot delaminate, separate or peel away in layers. [2]

Fibreglass products usually rely on a surface coat over reinforced layers. Acrylic baths are often formed from acrylic sheet and reinforced underneath. These methods can work in lower-demand environments, but they introduce dependence on reinforcement, surface thickness, bonding quality and installation support.

In a maternity setting, where surface integrity is closely linked to infection control, durability and cleaning confidence, a solid chemically fused material gives hospitals a stronger foundation.

Strength and rigidity for real hospital use

A filled water birth pool must remain stable and reassuring. It should not flex, creak, bow, buckle or shift under the combined load of warm water, maternal movement and staff support.

Ficore provides exceptional structural integrity. It does not need a metal or timber chassis to hold its shape, and it enables the pool to perform as one strong, integrated form. [1][2]

This rigidity matters in practice. A stable pool gives mothers confidence as they move, turn, lean, kneel, sit and rise. It gives midwives dependable support points. It also reduces the risk of movement, stress points or seal failures that can arise when a product depends heavily on added reinforcement.

A harder, smoother surface that stays easier to clean

The surface of a birth pool has to stay smooth. Scratches and dull areas are not merely cosmetic; they can make cleaning more difficult and may create microscopic irregularities where contamination is harder to remove.

Ficore’s surface is made from isophthalic neo-pentyl-glycol and is documented as 50% harder than acrylic when both materials are hot – a relevant comparison because water birth pools are used warm. Ficore abrasive wear testing also showed only 0.5% loss of reflectance after 10,000 cycles, compared with a typical 2% for acrylic. [2]

A harder, more durable surface helps the pool retain its appearance and cleanability through repeated use. For maternity units, this supports both long-term value and day-to-day infection prevention.

Better resistance to cleaning chemicals and thermal shock

Hospital water birth pools must be cleaned and disinfected thoroughly between uses, using locally approved procedures. The material must tolerate repeated exposure to cleaning agents, warm water, temperature changes and routine descaling without losing surface quality.

Ficore is resistant to most chemicals, including acid and alkaline solutions such as limescale remover. It is also able to withstand continuous exposure to hot water at 80°C and tolerate thermal shock caused by alternating hot and cold water. [2]

This margin is important. A material that softens, crazes, dulls or becomes harder to clean over time is not well suited to heavy clinical use. Ficore’s chemical and thermal resilience helps the pool remain hygienic, attractive and reliable over the long term.

Superior heat retention for comfort and efficiency

Warm water is central to the value of water immersion in labour. It helps mothers relax, move more freely and feel protected. When a pool loses heat too quickly, the experience is interrupted by top-ups, reheating and temperature management.

Ficore has a high insulation factor and, in Active Birth Pools, is used with double-wall construction to help retain warmth. The original page states that Active Birth Pools lose less than 0.7°C per hour and maintain water temperature far longer than conventional materials. [1]

Better heat retention has practical benefits for mothers, midwives and estates teams. It supports a calmer labour environment, reduces interruptions, can reduce water and energy use, and helps the pool perform consistently during longer periods of immersion.

A tactile surface that feels warm and secure

The way a birth pool feels matters. Labour is physical and instinctive. Mothers need surfaces that feel warm, smooth, supportive and secure rather than cold, hard or slippery.

Ficore is dense, tactile and warm to the touch. Its polished surface is smooth and comfortable, while its high adhesion factor helps reduce the risk of slipping. [1][2]

This combination is important in water birth because the mother is constantly changing position. She may sit, kneel, lean forward, rotate, brace herself, hold the rim, use the integrated seats or rise to leave the pool. The material should support that movement without making her feel unstable or exposed.

Hygiene built into the form

Infection prevention depends on more than a cleaning protocol. It also depends on the product’s shape, surface, seams, fittings and long-term condition.

Ficore allows Active Birth Pools to be manufactured as seamless one-piece forms with smooth organic contours. This reduces joints, crevices and dirt traps, making the pool easier to clean and inspect. It also allows essential support features to be integrated into the pool rather than added as surface-mounted accessories. [1][3]

This matters because healthcare-estates guidance for sanitary assemblies places emphasis on appropriate, cleanable surfaces and fittings in healthcare environments. Infection-control guidance for the built environment also recognises the importance of designing facilities and components so that they can be effectively cleaned and maintained. [6][7]

A pool that remains smooth, non-porous, chemically resistant and structurally stable gives maternity teams greater confidence between uses.

Design freedom: why Ficore improves ergonomics

The material does not only determine how strong the pool is. It also determines what the designer can safely create.

Ficore can be moulded into more highly sculpted forms, with sharper definition and more precise detail than many conventional bath materials. [1][2]

This is essential to the Active Birth Pools design philosophy. A water birth pool must support active birth, not passive immersion. Mothers need space to move, sit, kneel, squat, lean forward, brace, rest and change position. Midwives need safe access for monitoring, support, cleaning and emergency response.

Because Ficore combines mouldability with rigidity, hardness and surface integrity, features such as wide rims, integrated seats, recessed handholds and smooth water channels can be built into the product without compromising hygiene or stability.

Repairability protects the hospital’s investment

No material is completely immune to damage. The important question is what happens if damage occurs.

Ficore is fully repairable. Chips and scratches can be professionally repaired and the gloss finish restored. [2]

For hospitals, this is a significant advantage. Replacing a birth pool is expensive, disruptive and wasteful. A repairable material helps protect the asset, reduce downtime and extend the useful life of the room.

This is where whole-life value becomes more important than initial purchase price. A lower-cost material may appear economical at first, but if it scratches, flexes, dulls, requires more maintenance or needs earlier replacement, the real cost can be much higher over time.

Why Ficore is better suited to maternity environments

Ficore is not simply a premium version of acrylic or fibreglass. It is a better material platform for the specific demands of water birth.

For mothers

Ficore creates a pool that feels warm, smooth, secure and supportive. It helps mothers move freely, rest between contractions and use upright or forward-leaning positions with confidence.

For midwives

Ficore enables stable rims, integrated support points, recessed handholds and smooth surfaces that make the pool easier to work around, clean and inspect.

For infection prevention teams

Ficore supports seamless one-piece construction, non-porous surfaces, fewer dirt traps, chemical resistance and long-term surface integrity.

For estates and procurement teams

Ficore offers durability, heat retention, repairability, low maintenance and long service life. The result is better whole-life value and a product that remains fit for purpose for many years.

A superior material for a purpose-designed birth pool

Acrylic and fibreglass remain common because they are familiar, economical and easy to manufacture. They can be suitable for ordinary baths and showers, but hospital water birth pools require more than ordinary bath performance.

They require strength, stability, hygiene, cleanability, comfort, safety, repairability and value over the whole life of the room. Ficore meets these demands because it combines structural rigidity, surface hardness, chemical resistance, thermal performance and design freedom in one solid composite material.

That is why Active Birth Pools use Ficore® composite. It allows every pool to be built as a safe, supportive, ergonomic and hygienic birth environment – designed for mothers, midwives and the realities of modern maternity care.

Baths Are Simple Things. So Are Water Birth Pools. What Matters Most Is the Material They Are Made From

Why choice of material determines safety, usability, hygiene and over-all whole-life value

A bath is a simple object. It holds water. It needs to be comfortable, durable and easy to clean.

A water birth pool is also a simple object in principle. But in a hospital maternity unit, that simplicity is deceptive.

A hospital water birth pool must cope with repeated filling and emptying, frequent cleaning and disinfection, temperature change, the weight of water and mother, and the everyday demands of a busy clinical environment. In maternity settings, the pool is part of the care environment rather than a domestic bathroom product. NICE guidance recognises birth in water as an option to consider and discuss with women and pregnant people, which makes the design and maintainability of the pool itself important to safe service provision. [1]

So when hospitals compare water birth pools, the most important question is not: “What does it look like?” It is: “What material is it made from?”

Because the material determines almost everything that matters: strength, hygiene, durability, comfort, wet-use performance, expected service life, sustainability and long-term value.

Simple products expose material quality

Complex products can sometimes hide mediocre materials behind technology and features. A water birth pool cannot.

Its performance depends directly on the integrity of its structure and surface. The material has to create a pool that is rigid, stable, smooth, non-porous, easy to clean and able to withstand years of professional use.

Those qualities cannot be added later. They have to be built into the product from the start.

A lower-cost pool may look perfectly acceptable when it is new. Most products do. The real test comes later.

How does the surface perform after years of use? How does it respond to repeated cleaning and disinfection? Does it remain rigid? Does it scratch, chip, stain or deteriorate? Can it be repaired? How soon will it need to be replaced?

That is where material quality reveals itself.

The surface is not cosmetic

In a hospital, the surface of a water birth pool is not just part of its appearance.

It is the part that comes into contact with the water, the mother and the hospital’s cleaning procedures. It must remain smooth, intact, accessible and inspectable for effective cleaning.

Healthcare building guidance repeatedly emphasises surfaces and sanitary assemblies that can be cleaned, maintained and used safely in clinical environments. HBN 00-10 Part C deals specifically with sanitary assemblies, while HBN 00-02 provides design guidance for sanitary spaces in healthcare buildings. [2,3]

Damage matters. Scratches, chips, cracks, joints and surface-mounted fittings can create areas that are harder to inspect and clean. A pool may still look serviceable from a distance while its surface is becoming more difficult to maintain.

This is why hospitals should consider material quality and construction quality together. A strong structure with a poor surface is not enough. Nor is an attractive finish enough if the pool lacks rigidity or durability.

Seamless construction makes sense

Every unnecessary seam, joint, projection and attached fitting adds complexity.

Complexity means more edges to clean, more potential weak points and more places where water or contamination may collect.

A seamless, one-piece pool is simpler to inspect, simpler to maintain and easier to clean consistently. It also allows handgrips, support areas and rounded rims to be formed into the pool itself rather than added afterwards.

This matters because simplicity, when it is properly engineered, is not merely an aesthetic quality. It is a practical advantage. The same principle is reflected in infection-control design guidance: smooth, cleanable and impervious surfaces are preferred in clinical areas, and surfaces should be accessible and resistant to the effects of cleaning agents. [4]

Ficore®, fibreglass and acrylic

Fibreglass

Fibreglass pools are generally made by applying layers of glass-fibre reinforcement and resin into a mould. The visible surface is usually a gelcoat.

This method can produce complex shapes relatively economically. However, the performance of the pool depends heavily on the quality of both the laminate and the gelcoat.

Over time, gelcoat surfaces can become scratched, chipped, stained or worn. If damage exposes the underlying structure, cleaning can become more difficult and specialist repair may be required.

Fibreglass may offer a lower initial price, but hospitals should look carefully at surface durability, structural consistency and long-term performance.

Acrylic

Acrylic is widely used for domestic baths. It is usually made by heating and vacuum-forming a sheet of acrylic, then reinforcing it from underneath.

Acrylic can provide a smooth and attractive finish. However, the forming process can stretch and thin the material, particularly around deeper curves and more complex shapes.

The strength of the finished product therefore depends not only on the acrylic surface but also on the quality of the reinforcement behind it.

Acrylic can also be susceptible to scratching and may be affected by inappropriate cleaning products or abrasive methods. For domestic use, that may be acceptable. For repeated hospital use, it deserves closer scrutiny.

Ficore® Composite Resin

Ficore® is the specialist composite material used to manufacture Active Birth Pools.

Unlike acrylic, it is not a thin vacuum-formed sheet supported by a separate backing structure. Unlike conventional fibreglass, it does not rely on a thin decorative gelcoat over a laminate.

Ficore® is used to create a substantial, rigid, one-piece structure with a hard, smooth and non-porous surface. Active Birth Pools’ own Ficore® material specification describes it as a composite that is chemically fused and heat cured, rather than laminated or bonded. [12]

It is designed for repeated professional use in maternity environments where the pool must be filled, emptied, cleaned and disinfected again and again over many years.

It also enables important ergonomic features to be moulded directly into the pool, including handgrips, support areas and broad rounded rims. This produces a cleaner, stronger and more integrated design. [8,10]

Less slippery, more tactile and warm to the touch

Ficore® has a greater adhesive factor than fibreglass or acrylic. In practical terms, its surface is less slippery than fibreglass or acrylic and more slip resistant than those materials.

That does not mean Ficore® should be described as slip-proof. No wet surface should be. It does mean that Ficore® offers a more secure-feeling surface for mothers who need to move instinctively and change position during labour.

Ficore® also has a warmer and more tactile feel than fibreglass or acrylic. Because a mother in labour is in close, continuous contact with the pool — leaning on the rim, bracing against the sides, resting her arms, or placing her hands and feet against the surface — this sensory difference matters.

Compared with the harder, colder and more plasticky feel often associated with fibreglass and acrylic, Ficore® feels more substantial, reassuring and comfortable to touch. Its smooth, solid surface gives the pool a softer tactile quality without compromising cleanability or durability.

Together, these qualities can make the pool feel less clinical and more inviting, helping mothers relax into the water and move with greater confidence. In a birth environment, small sensory differences can have a meaningful effect on how secure and supported the pool feels in use.

Durability matters far beyond the product itself

Durability is not just about whether a pool continues to look good. In a hospital, durability has clinical, operational and financial consequences.

When a fixed water birth pool needs replacing, the cost is not limited to the price of a new pool.

The room may need to be taken out of service. Plumbing must be disconnected. The old pool must be removed and disposed of. Floors, walls and seals may need making good. A new pool must be delivered, installed, connected and tested.

All of that takes time, money and planning. It may also temporarily reduce the number of birth rooms available to mothers.

A more durable pool reduces the likelihood of this disruption. That is why the service life of the material matters so much.

Ficore® water birth pools are engineered for a working life exceeding 25 years in demanding hospital environments. That longevity changes the value equation completely. [11,13]

Sustainability begins with longevity

Sustainability is often reduced to one question: “Can this material be recycled?” That matters, but it is not the whole picture.

A product that needs replacing every few years creates repeated environmental costs through raw materials, manufacturing, packaging, transport, installation and disposal.

A product that remains in service for decades spreads the environmental cost of its manufacture across a much longer working life.

That is one of the strongest sustainability arguments for Ficore®. Its durability can reduce the need for replacement, which in turn can reduce material consumption, manufacturing demand, transport, packaging, installation work, disposal and disruption within the hospital.

There is also another important factor: repairability. Where appropriate, accidental damage to Ficore® can be professionally repaired. That may allow the pool to remain in service rather than being discarded and replaced.

A product that can be maintained and repaired is inherently more sustainable than one that becomes disposable when damaged. Durability and sustainability are not separate benefits. They are closely connected. [11]

The lifetime guarantee

Active Birth Pools offer a lifetime guarantee on Ficore® water birth pools, subject to the published terms and conditions.

That guarantee covers structural failure, loss of rigidity, leakage and surface breakdown. [9]

A guarantee of this scope is only possible when there is real confidence in the material, the design and the manufacturing process.

It is not simply a marketing statement. It reflects the belief that the pool has been made to endure.

The guarantee also makes an important point about value. The higher initial cost of a Ficore® pool is not simply the price of a premium material. It is the price of a product designed for long-term use, supported by a manufacturer prepared to stand behind its structural integrity.

Purchase price is not lifetime cost

Two water birth pools may perform the same basic function. One may cost less initially.

But if that pool deteriorates earlier, requires more maintenance, is harder to repair or must be replaced several times during the period in which a Ficore® pool remains operational, the lower purchase price may prove misleading.

The true cost of a water birth pool includes the original purchase, installation, maintenance, repair, downtime, replacement, removal, disposal and disruption to the maternity unit.

That is the difference between purchase price and whole-life value.

A higher-quality pool can cost more at the beginning and still cost less over its lifetime. Price is what the hospital pays on day one. Value is what the hospital receives over decades.

Why Active Birth Pools use Ficore®

Active Birth Pools use Ficore® because a hospital water birth pool must do more than look good when it is first installed.

It must remain strong, rigid, cleanable and dependable through years of repeated professional use. It must perform well when wet. It must support ergonomic design. It must be repairable where appropriate. It must reduce the likelihood of premature replacement. And it must provide hospitals with confidence that their investment will continue to deliver value over the long term.

Ficore® makes that possible.

Its quality allows Active Birth Pools to offer a lifetime guarantee. Its durability supports a working life exceeding 25 years. Its greater adhesive factor makes it less slippery than fibreglass or acrylic and more slip resistant than those materials, while its warmer, more tactile feel makes it more comfortable and reassuring to touch. Its one-piece construction supports hygiene, strength and integrated ergonomic design.

The result is not simply a pool made from a different material. It is a pool designed to remain part of the maternity environment for decades.

Material matters most

A water birth pool does not need to be technologically complicated. It needs to be exceptionally well made.

Its safety, hygiene, comfort, durability, sustainability and long-term value all begin with the material.

A better material can produce a stronger pool, a more durable surface, a less slippery, warmer and more tactile wet-use experience, a longer service life, less waste and better whole-life value.

It can also give the manufacturer enough confidence to guarantee the product for life.

Baths are simple things. Water birth pools are simple things too. And precisely because they are simple, the material they are made from matters most.

Procurement questions for hospitals

When comparing water birth pools, hospitals should ask practical, material-led questions:

  • Is the pool a seamless, one-piece structure or does it rely on joints, seams or attached fittings?
  • Is the surface hard, smooth, non-porous and accessible for inspection and cleaning?
  • How does the surface perform when wet, especially when a mother kneels, braces or changes position?
  • What is the expected working life in a hospital maternity environment?
  • Can accidental damage be professionally repaired?
  • What exactly does the warranty cover: structure, rigidity, leakage and surface breakdown, or only limited defects?
  • What are the likely whole-life costs once installation, downtime, replacement and disposal are included?

Creating Better Water Birth Pools Through Ergonomic Design

A water birth pool is not simply a vessel for warm water. In a maternity unit it becomes part of the care environment, part of the mother’s support system and part of the midwife’s working space.

Good ergonomic design recognises this. It considers how the mother moves, rests, leans, kneels, sits, rises and leaves the pool. It also considers how the midwife observes, listens, supports, monitors, cleans, records and responds if assistance is needed.

When ergonomics is treated as an afterthought, the pool may look acceptable but perform poorly. Mothers may have fewer safe positions to use. Midwives may be forced to bend, reach, twist or kneel for long periods. Cleaning may be harder than it should be. Emergency access may be compromised.

When ergonomics is built into the design from the beginning, the pool becomes a safer, calmer and more effective environment for labour and birth.

A well-designed birth pool supports instinctive movement for the mother and safe working posture for the midwife.

Supporting the physiology of labour

Water immersion is valued because it can help women relax, reduce the perception of pain and move more freely during labour. NICE recommends offering women the opportunity to labour in water for pain relief, with attention to water temperature, cleanliness and the manufacturer’s guidance for birthing pools. [2]

For these benefits to be realised fully, the pool must support the body rather than restrict it. The mother needs space to change position instinctively, freedom to use upright and forward-leaning postures, and secure surfaces that allow her to brace, rest and move with confidence.

An ergonomic birth pool should therefore provide generous internal space, appropriate water depth, comfortable contours, integrated handholds and supportive surfaces. These features encourage active birth rather than passive immersion.

The aim is not to prescribe one correct labour position. It is to make many useful positions possible: kneeling, sitting, squatting, leaning forward, resting sideways, rotating through the pelvis, or rising from the pool when necessary.

Designing for mothers: comfort, confidence and control

Labour is physical, instinctive and highly individual. A mother should not have to fight the pool to find comfort. The internal shape should invite movement, not limit it.

Smooth transitions between surfaces help reduce pressure points and muscular strain. Supportive seats and ledges can give the mother places to rest between contractions without leaving the water. Integrated handholds can help her stabilise herself without relying on the midwife for every change of position.

This matters because control and confidence are central to a positive birth environment. When the pool supports the mother’s natural movements, she can respond more easily to the sensations of labour and remain actively involved in the birth process.

The design should also make entry and exit feel secure. Mothers may need to enter the pool during labour, leave for observations, change environment, use the toilet, or exit quickly if clinical circumstances change. Good ergonomic design anticipates these real situations.

The ergonomics of entering the pool: sit and swivel

Entering the pool should not require climbing, stepping down into water or relying heavily on the midwife for balance. The sit-and-swivel method allows the mother to sit securely on the extra-wide rim, turn her body and lower herself into the water in one controlled movement.

This reduces the risk of slips, over-reaching and awkward weight transfer at one of the most vulnerable moments of pool use. It also helps protect midwives by reducing the need to support the mother’s full body weight during entry.

For hospitals, this makes the pool easier to use consistently with women of different heights, body shapes, levels of mobility and stages of labour. Safe entry is not a minor detail; it is a central ergonomic requirement.

Designing for midwives: reducing strain and supporting good practice

Midwives are central to the safe use of water in labour and birth. Yet poorly designed pools can place unnecessary strain on their backs, shoulders, necks, wrists and knees.

The Health and Safety Executive identifies bending, crouching, stooping, stretching, twisting, reaching, repetitive work and prolonged tasks as risk factors for work-related musculoskeletal disorders. Employers must manage these risks where they arise. [5]

In a birth pool room, those risk factors can occur when the rim is too narrow, the pool is too deep to reach into comfortably, the surround obstructs access, or the midwife has no stable working surface. A poorly shaped pool can force the midwife into awkward postures at the very moments when calm, precise support is needed.

Ergonomic design helps reduce this risk. Wide, rounded rims allow the midwife to lean and support her forearms. Recessed surrounds allow closer access to the mother. Smooth external forms reduce obstruction. Clear access around the pool supports observation, auscultation, assistance and emergency response.

This is not only an occupational-health issue. A midwife who can work in a balanced, supported posture is better placed to give attentive, reassuring and clinically effective care.

A pool must work as part of the clinical environment

Hospital equipment has to work in real clinical rooms, not idealised drawings. The pool must integrate with plumbing, drainage, cleaning routines, room layout, emergency protocols, access requirements and infection-prevention procedures.

NICE advises that baths and birthing pools should be kept clean using agreed local microbiology or infection-control guidance and, for birthing pools, in accordance with the manufacturer’s guidelines. [2]

Ergonomic design therefore includes cleanability. Rounded edges, smooth surfaces, one-piece construction, accessible fittings and minimal dirt traps all make the pool easier to clean, inspect and maintain. A pool that is comfortable but difficult to clean is not a good maternity product.

Functionality also includes access for the midwife, the mother’s partner and additional staff if assistance is required. The pool should support normal physiological birth but also allow clinical teams to act promptly when circumstances change.

Access must be designed in, not improvised

Most water births are calm and straightforward, but every maternity environment must be prepared for the unexpected. Ergonomics is therefore closely linked to clinical safety.

A well-designed pool should allow the mother to be supported safely, repositioned when needed and assisted out of the water if the clinical situation requires it. There must be adequate working access around the pool and a rim geometry that supports staff without forcing unsafe posture.

Design details that appear small in a showroom can become critical in practice: the height of the rim, the depth of the water, the distance a midwife has to reach, the stability of handholds, the shape of the interior seats and the clarity of the floor area around the pool.

The best design is the one that makes good practice easier under pressure.

The ergonomics of emergency evacuation

Emergency evacuation must be planned into the shape of the pool, not solved by staff improvising under pressure. The rim, internal seat, handholds, working height and surrounding floor space all affect how quickly and safely a mother can be assisted from the water.

Active Birth Pools’ extra-wide rim and internal support features are designed to help staff raise and transfer the mother with the assistance of buoyancy, reducing unnecessary lifting where possible. Where local protocols require an evacuation net or sling, the pool room should provide clear access and enough staff working space to use it safely.

Good evacuation ergonomics protects everyone: the mother, the baby and the maternity team. It supports calm, coordinated action while reducing bending, twisting, reaching and hazardous manual handling for midwives.

Ergonomics and manual handling

Manual handling in healthcare includes supporting or moving people, not just lifting objects. NHS Employers notes that employers must protect staff from hazardous manual handling and follow a hierarchy of avoiding, assessing and reducing risk where hazardous handling cannot be avoided. [6]

This principle is directly relevant to water birth pool design. A pool should reduce unnecessary handling by helping mothers move independently where possible. Integrated handholds, supportive seats and secure internal surfaces allow mothers to reposition themselves with less physical intervention from staff.

At the same time, the design should reduce the physical demands placed on midwives when they do need to help. Access, working height, rim width, clear floor space and stable support points all influence the amount of reaching, bending and force required.

In other words, ergonomic design is a form of risk reduction. It does not replace training or local protocols, but it makes safer practice easier to achieve consistently.

Why the internal design of the pool matters

The inside of a birth pool determines how the mother uses it. A simple open tub may allow immersion, but it does not necessarily support active labour. A purpose-designed water birth pool should provide a range of intuitive options.

Internal seats give the mother places to rest while remaining immersed. Handholds allow her to stabilise herself during contractions and position changes. Contoured walls support forward-leaning postures. Sufficient length, width and depth allow the pelvis to move freely.

These features must be integrated into the form of the pool, not added as awkward accessories. Integrated design is cleaner, stronger and more intuitive. It also reduces the number of separate components that could loosen, obstruct cleaning or create maintenance issues.

Why the external design matters just as much

The outside of the pool affects the midwife’s body. If the rim is too thin, sharp or high, the midwife may not be able to work comfortably. If the base or surround prevents close access, she may have to lean further than is safe. If the room layout is not considered, staff may struggle to reach the mother quickly.

Active Birth Pools are designed around the mother and the midwife together. The pool must be beautiful, but beauty is not the main objective. The main objective is safe, effective, comfortable use throughout labour, birth, cleaning and maintenance.

This is why wide rounded rims, smooth external contours, recessed access, integrated support features and appropriate working heights are not optional refinements. They are core safety and usability features.

Design for dignity

Ergonomic design is also about dignity. A mother using a birth pool may feel physically exposed, emotionally intense and highly dependent on the room around her. The pool should make her feel held, supported and protected.

Comfortable surfaces, secure support, warm water, intuitive movement and calm access all contribute to dignity. So does the ability for midwives to provide care without intrusive or awkward manoeuvres.

The goal is a pool that supports the mother’s autonomy while allowing the midwife to remain close, observant and ready to help.

A better pool supports everyone in the room

Ergonomic design is sometimes misunderstood as a comfort feature. In water birth pool design it is much more important than that.

For mothers, it supports movement, rest, immersion, confidence and physiological labour. For midwives, it supports safer working posture, closer access and more effective care. For hospitals, it supports infection prevention, manual-handling risk reduction, efficient cleaning, room functionality and long-term value.

Recent evidence also reinforces the importance of supporting safe access to water immersion. NICE’s 2025 evidence review noted that new evidence on water birth in low-risk, term, singleton pregnancies was generally low to very low certainty, but consistent in direction for several potential benefits, with the committee considering the net benefit positive while also identifying the need to communicate specific risks such as umbilical cord snapping. [3]

The POOL cohort study similarly concluded that, among women using water immersion during labour, remaining in the pool to give birth was not associated with an increase in adverse primary maternal or neonatal outcomes. [4]

This makes the design of the pool itself even more important. If water immersion is to be offered safely and confidently, the product must be designed for real maternity use.

Ergonomics is not a luxury

Ergonomic design in water birth pools is not a luxury, cosmetic preference or marketing detail. It is fundamental to safety, comfort, dignity and good clinical practice.

A purpose-designed birth pool should help mothers move instinctively, help midwives work safely and help hospitals maintain a clean, efficient and clinically appropriate birth environment.

That is the design philosophy behind Active Birth Pools. Every curve, rim, seat, handhold, surface and access point should earn its place. The result is a water birth pool designed not simply to hold water, but to support the whole experience of labour and birth.

Designing for Real Access: Why Wall-Mounted Birth Pools Outperform Freestanding Models

Why practical clinical access, room efficiency and unobstructed working space matter more than the appearance of 360-degree access.

A freestanding pool does not automatically provide better access. Water columns, plumbing fixtures, hand grips, steps and room features can obstruct the rim. An Active Birth Pools wall-mounted model uses only approximately 500 mm of the perimeter at the wall, leaving a broad, clear working edge with no rim-mounted metalwork or plumbing.

When hospitals plan a water birth room, one of the first decisions is whether to install a wall-mounted or freestanding pool.

A freestanding pool is often promoted on the basis that it provides “360-degree access”. At first sight, this sounds persuasive. If a pool stands away from the wall, it appears that midwives should be able to approach the mother from every direction.

In practice, however, physical space around a pool is not the same as usable clinical access.

The questions that matter:

The important question is not simply whether somebody can walk around the outside of the pool. The design should instead be judged by whether the midwife can get close enough to the mother, work without excessive bending or reaching, and use a clear section of the rim without taps, spouts, handrails or other obstructions.

Planners should also consider whether more than one member of staff can reach the mother when assistance is required, whether the room retains space for essential maternity equipment, whether cleaning can be carried out efficiently, and whether any additional space and expenditure deliver a genuine clinical benefit.

When these questions are considered carefully, a well-designed wall-mounted water birth pool will often provide more useful access than a freestanding pool.

The difference between theoretical access and usable access

The claim that a freestanding pool provides access around its complete perimeter assumes that the whole perimeter remains clear. That is frequently not the case.

Freestanding pools commonly require a water column, rim-mounted taps, a bath filler or spout, hand grips or handrails, control valves, access panels, associated pipework, entry steps and clearance from doors or movable room fittings.

Each of these features occupies space. More importantly, some obstruct the pool rim and prevent a midwife from working comfortably at that position. A section occupied by a water column is not a working position. A projecting handrail can prevent a midwife from leaning comfortably against the pool. Rim-mounted taps and metal fittings can restrict where staff place their hands and forearms.

This means that “360-degree access” may exist on a floor plan but not during an actual labour. A design should be assessed according to the amount of clear, comfortable and clinically useful working edge it provides—not simply according to whether the pool touches a wall.

Our wall-mounted pools do not sacrifice access

There is sometimes an assumption that placing a pool against a wall makes the rear third inaccessible. That is not true of a purpose-designed Active Birth Pool.

The wall-mounted flange occupies only approximately 500 mm of the pool perimeter. The remainder of the pool projects into the room and remains available to the mother and the maternity team.

There is no rim-mounted metalwork, plumbing or filler mechanism interrupting the principal working edge. The broad pool rim remains clear, allowing midwives to position themselves where they can observe, communicate and provide care.

The relevant comparison is not between a freestanding pool with complete access and a wall-mounted pool with access to only half of the pool. It is between a freestanding pool whose nominal perimeter may be interrupted by a water column, plumbing fixtures, handrails and surrounding room features, and a wall-mounted pool with a small wall connection and a substantially unobstructed working perimeter.

Once the obstruction created by fixtures and fittings is taken into account, the wall-mounted model may provide more useful access—not less.

Clear rim space is more important than walking space

A midwife does not provide care simply by walking around the outside of a birth pool. She must be able to sit, kneel or stand close to the mother and work in a stable, comfortable position.

Taps, projecting spouts, surface-mounted grips and other fittings can prevent the midwife from resting her forearms comfortably, increase the distance between the midwife and the mother, restrict hand placement, interfere with observation and monitoring, create potential impact points and make cleaning more complicated.

Active Birth Pools are designed with a clear working edge. The plumbing is separated from the principal clinical access area rather than occupying positions where midwives need to work.

The pool’s external shape also affects access

Access should not be measured only at floor level. A pool may have open floor around it but still force a midwife to lean across a wide or vertical external wall. If she cannot bring her knees and legs beneath the rim, her upper body remains too far away from the mother.

The distinctive concave external profile of Active Birth Pools allows the midwife to sit closer to the pool. Her knees can be positioned beneath the rim, helping her maintain a more upright and balanced working posture. The wide, rounded rim provides a comfortable surface on which the mother or midwife can rest.

Access is therefore created through the relationship between the pool’s shape, its rim and the person using it—not merely through the amount of empty floor surrounding it. Manual-handling guidance emphasises that risk is influenced by posture, reach, repetition, workplace layout and the physical design of the task.[1][2]

Freestanding pools occupy more of the birth room

A birth room must accommodate considerably more than the pool itself. Depending on local requirements, the room may also need space for a birthing bed, seating, monitoring equipment, neonatal equipment, an emergency trolley, a portable hoist or other evacuation equipment, clinical storage, staff circulation, birth partners and access to doors and sanitary facilities.

A freestanding pool must be positioned far enough from surrounding walls and fittings to create circulation space around it. That circulation zone can substantially increase the pool’s total spatial footprint.

A water column also occupies floor space. It requires installation, anchoring, pipework and clearance. Although it can provide a location for plumbing fixtures, it does not make the pool itself smaller or necessarily create better clinical access.

A wall-mounted installation uses the perimeter of the room intelligently. It places one small section of the pool against a surface that would not ordinarily serve as a clinical working position, while leaving the principal access areas facing into the room. This can release valuable space for the mother, midwives, equipment and emergency procedures.

A water column does not automatically improve access

Active Birth Pools can also be supplied in freestanding versions with a water column when the architectural design or intended room layout genuinely requires it. However, the water column does not create additional access by itself.

It occupies a position adjacent to the pool and must contain or support plumbing controls, pipework and potentially handrails. That section of the perimeter is therefore not equivalent to a completely clear working position.

A freestanding option may be appropriate where the pool must be located centrally, the walls cannot accept the necessary services, the room has been specifically planned around a central pool, or the building makes a wall-mounted installation impractical.

These are legitimate architectural reasons. But freestanding construction should not be selected solely on the assumption that it automatically delivers superior access.

Where the room allows a wall-mounted installation, adding a water column may increase the amount of floor space required, the installation work, the number of interfaces and sealed junctions, the quantity of materials, the plumbing complexity and the project cost. Unless it provides a specific, demonstrable benefit, the hospital may be paying more and sacrificing space without gaining meaningful clinical access.

Simpler installations can support easier cleaning

Water birth pools used in hospitals are subject to rigorous cleaning and infection-prevention procedures. Public health guidance has recognised that fixed hospital birth pools are managed through stringent infection-control measures and monitoring.[3]

The pool and its surroundings must be designed so that staff can reach, inspect, clean and dry the necessary surfaces. Every additional fitting, junction, projection and floor penetration creates another area that must be considered within the cleaning regime.

Rim-mounted metalwork and plumbing can make it harder to clean the complete pool edge. Water columns create additional external surfaces and junctions with the floor. Handrails and fittings introduce further contact points and interfaces.

A wall-mounted pool sealed appropriately to the wall and floor can create a clean, permanent installation with fewer external components occupying the room. Its principal rim remains clear and accessible for cleaning. NICE guidance states that units offering labour in water should have protocols governing pool use and cleaning, reinforcing the importance of considering cleanability at the specification stage.[4]

Better use of the construction budget

A hospital is not purchasing only a pool. The total project may include transportation, plumbing fixtures, pipework, structural or floor preparation, electrical or mechanical coordination, installation labour, sealing, room finishes, commissioning and access for future maintenance.

A freestanding installation with a water column is likely to require more material and installation work than the equivalent wall-mounted pool.

It may also influence the size of the room itself. In a new-build project, increasing the room area to preserve circulation around a freestanding pool can affect construction, flooring, ceilings, lighting, ventilation and ongoing cleaning.

The correct procurement question is: which arrangement provides the best combination of clinical access, ergonomic performance, room efficiency, infection prevention, installation simplicity and lifetime value? In many maternity settings, the answer will be a wall-mounted pool.

Clinical access should be tested on the actual plan

Architects, planners and maternity teams should examine proposed layouts at an early stage. The working perimeter of the pool should be marked on the floor plan together with the wall-mounted flange or water column, taps and filler positions, handrails, pool entry points, doors and their opening arcs, fixed furniture, the birthing bed, emergency equipment, staff working positions and routes into and out of the room.

The team should test where a midwife can sit or kneel close to the pool, which parts of the rim are obstructed, whether a second midwife can approach, whether the mother can enter and leave without unnecessary obstacles, whether emergency equipment can be brought into position and whether all necessary surfaces can be cleaned.

This exercise will normally reveal that an apparently accessible perimeter is not always a usable perimeter.

Emergency planning depends on the whole room

No birth pool can replace appropriate staffing, training, risk assessment or local emergency procedures. However, pool design and room layout should support those procedures.

Access for emergency assistance depends on the mother’s position, the number of staff present, the pool rim and internal support features, available lifting or evacuation equipment, the location of the bed or trolley, clear floor space and rehearsed local procedures.

A freestanding pool that consumes more of the room can reduce space available for the equipment and staff movement required during an emergency. Conversely, a thoughtfully positioned wall-mounted pool can preserve a larger, clearer working zone in front of and around the accessible sides of the pool.

The objective is not to allow staff to stand at every theoretical point around the perimeter. It is to create sufficient clear, strategically positioned and ergonomically effective access where it is most useful.

Wall-mounted does not mean less flexible

A well-designed wall-mounted pool can support a wide range of maternal positions. The mother can kneel, squat, sit, lean forwards, rest against the rim, use the internal support features, turn within the water and move between positions instinctively.

Water immersion itself supports buoyancy and freedom of movement. Research and clinical guidance recognise the role of water in supporting comfort, relaxation and movement during labour.[5][6]

The mother’s freedom inside the pool does not depend on whether the outside is accessible from every direction. It depends primarily on the pool’s internal dimensions, water depth, support features, material, temperature and ergonomic design.

Similarly, the midwife’s ability to provide care depends more on clear working positions and good reach than on an uninterrupted walking route around the complete exterior.

When does a freestanding pool make sense?

A freestanding water birth pool remains a useful option in the right project. It can make sense when the room is exceptionally large, a central location forms part of the clinical plan, services must rise through the floor, no suitable wall is available, the building’s construction prevents wall installation, or the layout has been designed specifically to preserve effective access around the pool and water column.

Active Birth Pools supplies freestanding models for precisely these situations. The important point is that freestanding installation should be selected because the room and project require it—not because of an untested claim that it always provides better access.

The most effective solution is often the simplest

Good healthcare design is not achieved by adding components without a clear purpose. It is achieved by removing unnecessary obstacles and making the best use of the available room.

A wall-mounted Active Birth Pool commits only a small section of the perimeter to the wall, leaves the main working edge unobstructed, avoids rim-mounted taps and metalwork, allows midwives to get close through its concave external profile, preserves more of the room for clinical use, requires fewer freestanding components and generally costs less than an equivalent freestanding arrangement with a water column.

This is why wall-mounted pools often make more practical sense. The value of a water birth pool should never be measured by how much empty floor can be seen around it. It should be measured by how safely and effectively the mother and midwife can use it.

Conclusion

The phrase “360-degree access” sounds reassuring, but it does not provide a complete picture.

A freestanding pool may be surrounded by floor space while substantial sections of its perimeter remain obstructed by a water column, plumbing fixtures, hand grips, steps, doors or other room features.

By contrast, the wall-mounted flange of an Active Birth Pool occupies only approximately 500 mm. The remaining perimeter provides a broad, clear working edge without rim-mounted metalwork, plumbing or fixtures.

The result can be more genuinely usable access, better midwife positioning, less wasted floor space, simpler installation, easier room planning and better overall value.

Freestanding pools have an important place where the architecture requires them. But where a wall-mounted installation is possible, there is often little or nothing to gain by moving the pool into the middle of the room.

In many cases, the wall-mounted pool is not the compromise. It is the better-designed solution.

Must See Video: Freedom of Movement in a Water Birth Pool

This short video shows how an Active Birth Pool gives mothers the space and freedom to move naturally throughout labour and birth.

Warm water allows mothers to explore a wide range of upright, kneeling and supported water birth positions. They instinctively use the shape and internal features of the pool to find positions that feel comfortable, secure and beneficial as labour progresses.

Freedom of movement, together with the relaxing effects of warm water, creates favourable conditions for the release of oxytocin and the natural progression of physiological labour.

The video has now been viewed more than 12 million times on YouTube, demonstrating the worldwide interest in movement, water birth and natural approaches to labour.

Sustainability and Life Cycle Value

Sustainability starts with choosing the right product

When hospitals assess the sustainability of a water birth pool, the discussion should not begin and end with the purchase price.

A hospital birth pool is a long-term item of healthcare sanitary ware. It will be installed in a demanding maternity environment, filled and emptied repeatedly, cleaned and disinfected frequently, used by many mothers and midwives, and expected to support safe, efficient care for many years.

For this reason, sustainability must be assessed over the whole life of the product.

A cheaper pool that requires regular repair, becomes difficult to clean, loses surface integrity, creates maintenance issues or needs replacing after a relatively short service life may prove far less sustainable than a higher-quality pool designed to last for decades.

True sustainability is about durability, safety, hygiene, repairability, operational efficiency and long-term value. [1]

Why life cycle value matters in maternity units

Hospitals do not simply buy birth pools. They create water birth facilities.

That means the pool has to work within a clinical room, connect safely with hospital water systems, support mothers in labour, allow midwives to work comfortably, enable effective cleaning, and remain reliable throughout years of use.

The real cost of a birth pool therefore includes:

  • the purchase price;
  • installation and room preparation;
  • maintenance;
  • cleaning and disinfection;
  • water safety management;
  • staff time;
  • downtime;
  • repairs;
  • replacement;
  • disposal;
  • the effect on room usability and service quality.

A product that appears cheaper at the point of purchase can become expensive if it compromises any of these areas.

By contrast, a pool designed for long-term hospital use can reduce waste, avoid premature replacement, support safer working practice and provide better value over its lifetime. [4]

Built from Ficore® composite for long-term use

Active Birth Pools are made from Ficore® composite, a proprietary material developed for the demands of professional maternity use.

Ficore® is central to the sustainability and life cycle value of our pools because it provides the strength, durability, surface quality and design freedom required for hospital birth environments. [2,3]

Unlike ordinary bath materials, Ficore® allows us to create highly sculpted, one-piece ergonomic forms with smooth, continuous surfaces and integral support features. This is important because a hospital birth pool must do more than hold water. It must support movement, comfort, access, cleaning, midwife ergonomics and risk reduction.

Ficore® also has important performance advantages over fibreglass and acrylic. It is strong, durable, warm to the touch, highly resistant to damage, and able to withstand the repeated cleaning and disinfection required in hospital use. Its highly polished surface is more tactile and, importantly, Ficore® has a greater adhesive factor and is less slippery / more slip resistant than fibreglass or acrylic. [2,3]

This comparative surface performance is important in a wet environment where mothers need to feel secure and supported while entering, leaving and moving within the pool.

Durability reduces waste

One of the simplest principles of sustainable procurement is to avoid unnecessary replacement.

A product that lasts longer creates less waste. It also reduces the environmental and financial costs associated with repeated manufacture, shipping, installation, removal and disposal.

Active Birth Pools are designed for decades of use in hospitals and maternity units. The older value and sustainability assessment stated a life expectancy of over 25 years, and Active Birth Pools continue to position long service life as a major advantage of Ficore® composite construction. [1,3]

This matters because birth pool replacement is not only a product cost. It can also involve disruption to maternity services, room downtime, contractor work, infection-control considerations and additional procurement activity.

When durability is built into the product from the beginning, sustainability is built into the whole room.

Smooth surfaces support cleaning and hygiene

Sustainability in healthcare cannot be separated from hygiene.

A water birth pool must be easy to clean, resistant to surface degradation and suitable for repeated disinfection. If the surface becomes damaged, roughened, cracked or difficult to clean, the pool may create avoidable maintenance and infection-control concerns.

NICE recommends that baths and birthing pools should be kept clean using a protocol agreed with the local microbiology department or infection-control guidance, and that birthing pools should also be cleaned in accordance with the manufacturer’s guidelines. [5,6]

This places practical importance on the surface material, the shape of the pool and the avoidance of unnecessary dirt traps.

Active Birth Pools are made as seamless, one-piece forms from Ficore® composite. The smooth, non-porous surface and absence of unnecessary surface-mounted fittings help make cleaning easier and more reliable. [2,3]

A pool that is easier to clean can support better room turnaround, reduce staff frustration and help maternity teams maintain confidence in the facility.

Water safety and hospital infrastructure

Hospital birth pools must also be considered in the context of healthcare water safety.

NHS England HTM 04-01 gives guidance on the legal requirements, design, installation, maintenance and operation of hot and cold water systems in healthcare premises. It is written for healthcare management, Water Safety Groups, design engineers, estate managers, operations managers, contractors and supply chain businesses. [8]

The Health and Safety Executive also identifies hot and cold water systems as a foreseeable source of legionella risk and highlights the importance of understanding system design, dead legs, outlets, thermostatic mixer valves and temperature control. [9,10]

For birth pools, this makes correct specification essential.

The most sustainable solution is not one with complicated integral plumbing, recirculation systems or difficult-to-access pipework. The most sustainable solution is one that supports safe, simple, maintainable hospital water services and avoids unnecessary systems that are difficult to clean, monitor or manage.

A well-designed birth pool should work with the hospital’s water-safety strategy, not against it.

Supporting NHS net-zero and social value goals

The NHS has committed to reaching net zero for the emissions it controls directly by 2040, and for the emissions it can influence by 2045. NHS procurement now places increasing emphasis on net zero, social value, carbon reduction planning and responsible supply chains. [11,12]

The NHS Net Zero Building Standard also provides technical guidance to support sustainable, resilient and energy-efficient healthcare buildings. [13]

This means that maternity-unit decisions should not focus only on capital cost.

They should also consider:

  • product lifespan;
  • embodied carbon spread over years of service;
  • repairability;
  • replacement frequency;
  • waste reduction;
  • operational efficiency;
  • water and energy considerations;
  • supplier responsibility;
  • local production and transport impacts;
  • contribution to staff wellbeing and service quality.

Active Birth Pools are hand-built to order in England from Ficore® composite. This supports skilled manufacturing, reduces reliance on disposable or short-life products, and aligns with a procurement approach that values quality, durability and responsible long-term performance. [1,3]

Sustainability also means protecting staff

A sustainable maternity service must protect the people who deliver care.

Birth pools that are awkward to use, difficult to access, poorly shaped or uncomfortable for midwives can contribute to strain, poor posture and inefficient working practice.

Active Birth Pools are designed around the needs of both mothers and midwives. Their ergonomic forms support freedom of movement for mothers while helping midwives maintain better working positions around the pool.

This is not an optional design extra. It is part of the life cycle value of the product.

A well-designed pool can support better staff experience, reduce avoidable physical strain and help maternity teams use the room with confidence. Over the life of the installation, those benefits matter.

The value of a better birth environment

NICE recommends offering women the opportunity to labour in water for pain relief. NICE also recommends supporting women and pregnant people with mobility issues to access water during labour and birth by carrying out an individualised needs assessment and making reasonable adjustments. [5,6]

This strengthens the case for maternity units to provide water birth facilities that are safe, accessible and suitable for a wide range of users.

A high-quality water birth pool can help create a calmer, more dignified and more supportive birth environment. It gives mothers space to move, change position, relax and feel secure. It gives midwives better access and a safer working relationship with the pool.

These are not just comfort benefits. They are part of a broader quality-of-care argument.

A birth pool that performs well for mothers, midwives and the hospital estate can support safety, dignity, choice, efficiency and reputation.

Why the lowest price is rarely the best value

Procurement teams are under pressure to obtain value for money. But value for money should never be confused with lowest initial cost.

A hospital birth pool should be assessed in the same way as other long-life healthcare infrastructure: by whole-life value.

The right questions are:

  • How long is the pool expected to last?
  • What is the material made from?
  • Is the surface durable and easy to clean?
  • Is the pool resistant to repeated disinfection?
  • Does the design reduce risk?
  • Does it support safe entry and exit?
  • Does it help midwives work comfortably?
  • Does it avoid unnecessary fittings, dirt traps and water-safety complications?
  • Can it be repaired if damaged?
  • Is technical support available before, during and after installation?
  • What is the cost of replacing a cheaper product earlier?

When these questions are asked, the case for long-life, hospital-grade design becomes clear.

OLYMPUS DIGITAL CAMERA

Sustainability in hospital birth pool specification is not achieved by choosing the cheapest product.

It is achieved by choosing a pool that is built to last, easy to clean, safe to use, supportive for mothers, practical for midwives, compatible with hospital water-safety requirements and capable of delivering value over decades.

Active Birth Pools are designed around these principles.

Made from Ficore® composite, hand-built to order in England and engineered for the realities of maternity care, they provide exceptional life cycle value by combining durability, hygiene, ergonomic design, safety and long-term performance.

For hospitals, this means fewer compromises.

For procurement teams, it means better value.

For estates teams, it means a more robust and maintainable facility.

For midwives, it means a safer and more comfortable working environment.

For mothers, it means a more secure, supportive and dignified place to labour and give birth.

The most sustainable birth pool is the one that continues to perform safely, hygienically and confidently year after year.

That is the purpose of Active Birth Pools.

Water Safety and Legionella Control for Hospital Birth Pools

A practical guide for maternity teams, estates departments, infection-prevention specialists, Water Safety Groups, designers and contractors

Core message: A birth pool should be treated as part of the healthcare water system. Safe design removes avoidable stagnation, keeps services simple and accessible, supports fresh filling for each use, and makes complete drainage, cleaning and monitoring easier.

Water safety and Legionella control for hospital birth pools

Hospital birth pool water safety begins long before the pool is filled. It depends on the design of the hot- and cold-water system, the route and frequency of water use, the position of outlets, the ability to drain and dry the pool, and the procedures used by maternity, estates and infection-prevention teams.

Legionella and other waterborne microorganisms can multiply where water is allowed to stagnate, where temperatures support growth, or where deposits and biofilm provide protection. In a maternity setting, the objective is not to treat the pool as an isolated product, but to integrate it into the hospital’s wider Water Safety Plan and system of control.

Active Birth Pools are purpose-designed hospital sanitary ware. They are intended to be filled with fresh mains water for each labour, emptied after use, cleaned and disinfected in accordance with local protocols and the manufacturer’s guidance. They are not recirculating spa pools and should not be operated as continuously heated or prefilled systems.

Why Legionella control matters in maternity environments

Legionella bacteria occur naturally in water and may grow in engineered systems when conditions are favourable. The Health and Safety Executive identifies temperature, stagnation, scale, sediment and biofilm as important risk factors. Control therefore depends on design, operation, maintenance, monitoring and clear responsibility. [1][2]

Birth pools deserve particular attention because warm water is used close to a mother and newborn. Published investigations have linked neonatal legionellosis with prefilled, heated and recirculating birthing tubs. These rare but serious cases reinforce a fundamental distinction: a hospital birth pool should be freshly filled for the individual mother and should not behave like a warm-water storage or spa system. [5][6]

The lesson is not that water birth itself creates Legionella. The risk arises when the water system, fittings or operating method allow microorganisms to grow and then expose the mother or baby.

Bring the birth pool into the hospital Water Safety Plan

NHS guidance in HTM 04-01 applies to the design, installation, commissioning, operation and maintenance of hot- and cold-water systems in healthcare premises. It is written for healthcare management, Water Safety Groups, design engineers, estates managers, operations managers, contractors and supply-chain businesses. [3]

The birth pool and its associated pipework, valves, outlets, hoses and drainage should therefore be considered by the Water Safety Group from the earliest design stage. Responsibility should not be divided between the maternity room designer, plumber, equipment supplier and clinical team without a single coordinated assessment.

The project should identify who owns the risk assessment, who approves the design, who commissions the system, who manages flushing and temperature monitoring, and who authorises the pool for clinical use.

Design out stagnation and unnecessary complexity

The safest water system is generally the simplest one that meets the clinical need. Long pipe runs, blind ends, oversized distribution pipework, seldom-used branches and redundant fittings can create areas of low flow or stagnation. HSE guidance emphasises designing, maintaining and operating water services to prevent or adequately control Legionella growth. [2]

Birth-pool services should be routed as directly as practicable, with accessible isolation, commissioning and maintenance points. Any arrangement that may hold warm water between uses should be challenged during design review.

The pool itself should have a free-flowing outlet and should drain completely. Surfaces and fittings that trap residual water make drying more difficult and can undermine an otherwise sound cleaning procedure.

Use fresh water for every labour

A hospital birth pool should be filled shortly before use with fresh water from the approved healthcare water system. It should not be filled in advance and held warm while waiting for a mother, and water should not be stored or recirculated between users.

Fresh filling reduces the opportunity for organisms to multiply in the pool water. It also makes the start of each use clear and auditable: the pool has been cleaned, rinsed as required, freshly filled and checked before the mother enters.

The filling time should be fast enough for clinical practicality without encouraging the unit to keep the pool prefilled. Appropriate flow rates and correctly sized services are therefore part of infection prevention as well as convenience.

Control water temperature without creating avoidable risk

HSE guidance notes that Legionella can grow in water systems between approximately 20°C and 45°C, particularly where stagnation is present. Temperature control in the building system is therefore a central control measure. [4]

Healthcare hot-water systems are normally managed at temperatures that limit bacterial growth, with safe delivery temperatures achieved at the point of use by an appropriate thermostatic arrangement. The specific design must follow HTM 04-01, local Water Safety Plan requirements and the project engineer’s assessment. [3]

The temperature used for labour is a separate clinical requirement. NICE recommends monitoring the woman’s temperature and the water temperature hourly, and states that the pool water should not be above 37.5°C. [7] Mixing for maternal comfort should occur at filling and use, not by maintaining a reservoir of lukewarm water within the system.

Position taps, spouts and hoses carefully

Outlets are critical parts of the water system. Their design and position affect flushing, cleaning, splash, aerosol generation, access and the possibility of contamination from hands or the pool environment.

Fittings should be selected for healthcare use and positioned so that they can be inspected, cleaned, maintained and replaced. They should not create hidden cavities or inaccessible water traps around the pool rim.

Flexible hoses require particularly careful governance. A hose that is left containing water, stored wet, allowed to touch the pool water or used for more than one purpose can become a contamination route. Where a hose is required, the Water Safety Group should approve its specification, storage, flushing, cleaning, replacement interval and connection arrangement. The design should also protect the mains supply from backflow in accordance with water regulations and local engineering requirements.

Manage little-used outlets and periods of low activity

Birthing rooms may have irregular patterns of use. A pool that is clinically important may still remain unused for days or weeks. The associated outlets must therefore be included in the hospital’s programme for little-used water services.

Local procedures should define flushing frequency, the volume or duration of flushing, responsibility, safe disposal to drain and record keeping. Flushing should be carried out in a way that avoids unnecessary aerosol and does not expose patients or staff to hot water.

After closure, refurbishment, commissioning work or an extended period of non-use, the pool services should be assessed and returned to use under the Water Safety Plan rather than simply opened and filled.

Drain, clean and dry after every use

Once the mother has left the pool, water should be discharged promptly through the designated drainage system. The pool should then be cleaned and disinfected using the local protocol agreed with infection prevention or microbiology and in accordance with the manufacturer’s guidance. NICE expressly requires this approach for birthing pools. [7]

Cleaning and disinfection are separate steps. Organic material and visible soil must be removed so that the disinfectant can act on the surface. Staff must use the correct product, concentration and contact time and must follow any rinsing requirement.

The design should allow all internal surfaces, the outlet and accessible fittings to be reached. After the procedure, residual water should not remain trapped in the pool or its accessories. A clean, dry pool provides a clear starting point for the next use.

Commissioning and handover are essential

A well-designed installation can still be compromised if debris, flux, construction contamination or stagnant commissioning water is left in the system. The birth-pool installation should be commissioned as part of the healthcare water system, not treated as a final decorative fitting.

Handover information should include as-installed drawings, valve and outlet identification, flushing points, cleaning instructions, product data, commissioning results, risk controls, maintenance requirements and the agreed operating procedure.

Maternity staff should understand what they are expected to check. Estates and infection-prevention teams should know which components require planned inspection, servicing, sampling or replacement.

Monitoring, records and response to concerns

An effective control scheme is supported by records. These may include flushing logs, temperature checks, servicing, cleaning records, microbiological sampling where indicated, corrective work and Water Safety Group review.

Routine Legionella sampling is not a substitute for good control. HSE guidance explains that testing should be based on the risk assessment and control scheme and carried out by competent people using appropriate methods. [8]

If results, temperatures, flow conditions or clinical observations suggest a problem, the pool should be managed under the organisation’s Water Safety Plan. This may include taking the outlet out of use, investigation, remediation, verification and formal approval before return to service.

Active Birth Pools: design principles that support water safety

Active Birth Pools are designed as fixed hospital sanitary ware with smooth, seamless internal surfaces and straightforward filling and drainage. The pools use fresh water for each labour and do not depend on pumps, jets, filters or recirculation systems.

Separating the water controls from the principal working rim can improve access for cleaning and maintenance. The Water Column option provides a dedicated location for services on freestanding installations, while wall-mounted arrangements can be integrated with an appropriate clinical-services panel.

The final safety of any installation depends on correct specification, installation, commissioning and operation within the hospital’s Water Safety Plan. Product design supports that system; it does not replace it.

Design principle: Do not manage waterborne risk by relying on cleaning alone. Begin with a simple, free-flowing system that avoids stored warm water, unnecessary pipework, inaccessible fittings and residual water.

A practical specification checklist

  • Include the birth pool and its services in the healthcare Water Safety Plan and Legionella risk assessment.
  • Obtain Water Safety Group input before the layout and water-service design are fixed.
  • Use a direct, appropriately sized hot- and cold-water supply with no avoidable dead legs or redundant branches.
  • Provide suitable temperature control in accordance with HTM 04-01 and the local engineering strategy.
  • Specify healthcare-appropriate outlets that can be accessed for inspection, cleaning, maintenance and replacement.
  • Assess any flexible hose as a water-safety component and define its storage, flushing, cleaning and replacement arrangements.
  • Provide backflow protection appropriate to the installation and local water regulations.
  • Ensure the pool fills quickly enough to avoid operational pressure to prefill it.
  • Use fresh water for each labour; do not store, continuously heat or recirculate pool water.
  • Ensure the pool and outlet drain completely and can be cleaned and dried without inaccessible water traps.
  • Include little-used outlets in the flushing and monitoring programme.
  • Commission, document and approve the installation before clinical use.
  • Give maternity staff clear operating, cleaning and escalation procedures.
  • Keep records and review performance through the Water Safety Group.

Frequently asked questions

Can Legionella grow in a birth pool?

Legionella can multiply in water systems where temperatures, stagnation, scale, sediment or biofilm support growth. A freshly filled, promptly emptied and properly maintained hospital pool presents a very different operating condition from a prefilled or recirculating heated tub. The full installation still requires risk assessment and control.

Are birth pools covered by HTM 04-01?

The pool’s hot- and cold-water services form part of the healthcare water system. Their design, installation, commissioning, operation and maintenance should be managed in line with HTM 04-01, HSE guidance and the organisation’s Water Safety Plan.

Does the pool need Legionella testing after every use?

No general rule requires testing after every use. Sampling should be determined by the risk assessment, control scheme and Water Safety Group. Monitoring temperatures, flow, flushing and maintenance remains essential.

What is the safest type of birth pool for a hospital?

A purpose-designed fixed pool with smooth, accessible surfaces, complete drainage and no pumps, jets, filters or recirculating water avoids many of the complexities associated with spa-style systems. The surrounding water-services design is equally important.

Who should approve the installation?

Approval should involve the hospital’s Water Safety Group together with maternity, estates, infection prevention, the Authorising Engineer or other competent water-safety adviser where applicable, designers, installers and the pool supplier.

How should a birth pool be cleaned?

Follow a local protocol agreed with infection prevention or microbiology and the manufacturer’s guidance. Remove visible contamination first, use the approved disinfectant at the correct concentration and contact time, rinse when required, drain completely and leave the pool clean and dry.

Are Active Birth Pools medical devices?

No. Active Birth Pools are purpose-designed hospital sanitary ware. They should be specified as part of the maternity room and its water, drainage, cleaning and maintenance systems.

Plan a safer hospital water birth installation

Active Birth Pools can provide dimensions, technical drawings, installation guidance and project support for maternity teams, architects, estates departments, Water Safety Groups and contractors. Early coordination helps ensure that the pool, outlets, Water Column or services panel, drainage and room layout form one coherent system.

Why Midwife Comfort and Safety Starts with Better Birth Pool Design

A birth pool is a workplace

A water birth pool is not simply a vessel for warm water. In a maternity unit it becomes part of the midwife’s working environment.

Midwives use the pool repeatedly. They observe, communicate, monitor, reassure, assist with entry and exit, support examinations where clinically appropriate, manage water temperature, help maintain a safe space around the pool and respond quickly when circumstances change.

That ongoing use is the reason midwife comfort, safety and wellbeing should be treated as a primary design requirement. If the pool forces poor posture, every use can add to physical strain. If the pool supports good working access, it helps midwives stay close, balanced and available throughout labour and birth.

This is the principle behind Active Birth Pools: the pool must support the people who use it every day.

Why ergonomic design matters to midwives

The Chartered Institute of Ergonomics & Human Factors explains that user-centred product design starts by identifying the key users early in the design process and researching their needs before the finished product is developed. In Case Study 18, Improving Birthing Pool Design, the Institute records that earlier barrel-shaped pools had not been designed for any of the users. Midwives were unable to monitor and examine mothers in the pool without putting strain on their back and neck. [1]

The same case study identifies the midwife as a key user who needs a comfortable working position, knee room beside the pool and the ability to reach the mother for examinations and monitoring. [1]

This is exactly where birth pool design becomes an occupational-health issue. The design either helps the midwife work close to the pool in a natural posture, or it creates an obstacle that the midwife has to work around.

The problem with vertical-sided pools

A pool with a solid vertical surround places a physical barrier between the midwife and the person in the water. The midwife may have to stand with feet wide apart, lean forwards over a narrow rim, twist from the waist or support weight through the arms and shoulders for prolonged periods.

These positions are uncomfortable in the moment and can become more significant when repeated across shifts, weeks and years. The issue is not only one difficult birth. It is cumulative exposure to avoidable strain.

The Health and Safety Executive identifies manual-handling risks to midwives and auxiliary staff who assist births in pools. These risks can arise from routine tasks, the position of the mother in the pool, and the position of the midwife while carrying out tasks at the pool or supporting entry and exit. [2]

The concave shape: giving the midwife knee room

The key ergonomic difference in Active Birth Pools is the concave outer profile.

Instead of forcing the midwife to work around a vertical wall, the recessed shape allows the midwife to sit closer to the pool with her legs naturally positioned beneath the rim, as if sitting at a desk.

This design principle is directly supported by Case Study 18, which identifies a concave side as a feature that provides knee room for the sitting midwife. [1]

Knee room matters because it changes the whole working posture. The midwife can sit closer, remain more upright, rest the arms, see clearly, communicate calmly and reach the person in the pool with less bending and stretching.

Reducing bending, reaching and twisting

HSE guidance on manual handling in birthing pools is clear: pool design should allow the midwife to get as close as possible and minimise bending and reaching over. [2]

This is one of the most important tests of a hospital birth pool. Can the midwife get close enough to work comfortably? Can she support the person in the water without excessive forward reach? Can she move around the pool without obstructions? Can she change position easily during a long labour?

Active Birth Pools are designed to answer yes to these questions. The concave outer form, wide rounded rim and unobstructed working edge are intended to reduce the awkward postures that can occur when staff have to lean over a fixed barrier.

HSE guidance on musculoskeletal disorders highlights the need to manage work-related risks such as manual handling, back pain and upper limb disorders. [3] In the birth-pool context, design should therefore help reduce avoidable physical loading wherever possible.

The extra-wide rounded rim

The extra-wide rounded rim is another midwife-centred design feature.

A narrow rim concentrates pressure into a small area of the forearm. A wider rounded rim allows the midwife to rest the forearms more comfortably while staying close to the pool. This can make a considerable difference during prolonged observation, reassurance and hands-on support.

The rim should also remain clear of taps and fittings. Midwives need freedom to move around the pool and choose the most appropriate position. A clear working edge supports better access, better posture and better responsiveness.

Supporting entry and exit protects midwives too

Although the primary focus of this article is midwives, entry and exit must be considered because they directly affect the midwife’s role and physical workload.

HSE identifies risks when midwives actively support entry or exit into the pool, or when the mother uses the midwife as support while entering or exiting. [2]

For this reason, pool design should reduce unnecessary lifting, pulling and steadying by staff. A secure sit-and-swivel approach over a wide, supportive rim gives the person entering the pool a more controlled method of access. It also helps the midwife guide rather than physically carry or hold body weight.

NICE recommends supporting women and pregnant people with mobility issues to access water during labour and birth through an individualised needs assessment and reasonable adjustments. [4] From the midwife’s perspective, this reinforces the need for pool design, room layout and local procedures to work together.

Emergency evacuation: designed in, not improvised

Emergency evacuation is another area where design directly affects the midwife’s work.

HSE advises that emergency procedures should identify what situations could arise, whether the mother can participate, how to get her out of the pool, how many staff or helpers are required and how to call for additional help. HSE also lists equipment that may be needed, such as an evacuation net, flotation aids, slide sheet, height-adjustable bed or trolley, hoist and slings. [2]

The pool should support these procedures rather than make them harder. Access around the pool, the working height, the rim, internal supports and the ability to move the person towards a safe exit point all affect how calmly and efficiently staff can respond.

Good design cannot replace training, staffing or local policy. But it can make the trained response easier to carry out.

Midwife comfort is a safety issue

Midwife comfort is sometimes treated as a soft benefit. It is not.

A midwife who can work close to the pool in a stable, supported position is better placed to remain attentive, calm and physically available. Good posture supports good practice. It helps midwives observe, listen, monitor, reassure and assist without unnecessary strain.

For midwives who use birth pools on an ongoing basis, the difference between an obstructive design and an ergonomic design is not theoretical. It is felt in the back, neck, shoulders, arms and wrists at the end of a shift.

The pool should never make the midwife’s work harder than it needs to be. It should support safe, skilled, compassionate care.

Designed for the people who use it every day

Active Birth Pools were developed from a user-centred ergonomic approach, including the work described in CIEHF Case Study 18 and the involvement of a health-service ergonomist working with midwives at Nottingham City Hospital. [1]

That approach remains central to the design today.

Every curve, rim, recess and support feature has a purpose. The concave side gives knee room. The wide rounded rim supports the arms. The clear working edge allows movement around the pool. The internal supports and access features help reduce avoidable strain during entry, exit and assistance. The overall form helps midwives get closer, reach less and work more comfortably.

A water birth pool should be beautiful, durable and easy to clean. But above all, it should work safely for the people who use it every day.

For midwives, better birth pool design means better access, less strain and a safer working position.

That is why midwife comfort and safety starts with better birth pool design.

How Water Birth Pools Help Mothers Have a Better Experience of Labour and Birth

A comprehensive, evidence-based introduction for parents, midwives and maternity teams

Updated June 2026

For many people, the idea of labouring or giving birth in water still feels unfamiliar. It may sound gentle, even beautiful, but they may wonder: Does it really help? Is it safe? Is it only for certain kinds of birth?

The simple answer is that warm water can be one of the most effective, low-intervention ways to support a woman through labour. A birth pool does not “do” birth for the mother. It gives her an environment in which her body can work more freely, more instinctively and often more comfortably.

Water supports weight. Warmth encourages relaxation. Privacy reduces tension. Buoyancy makes movement easier. Together, these effects can transform the atmosphere of labour from something clinical, exposed and stressful into something calmer, more protected and more mother-led.

This matters because birth is not only a medical event. It is a physical, emotional and hormonal process. The way a woman feels during labour can influence how she moves, how she copes, how safe she feels and how positively she remembers the birth.

What is water immersion in labour?

Water immersion means labouring in a deep bath or birth pool filled with warm water, usually deep enough to cover the mother’s abdomen. The mother may use the pool during the first stage of labour for comfort and pain relief, and she may choose to leave the pool before birth or remain in the water for the baby’s birth, depending on her circumstances, preferences and local clinical guidance.

A “water birth” usually means that the baby is born underwater and then brought gently to the surface. The baby does not breathe underwater; babies are born with protective reflexes, and the first breath normally occurs after the baby reaches air. This is why trained midwifery care, appropriate water temperature, calm handling and safe protocols are essential.

Why warm water helps

The most immediate effect of entering a birth pool is often visible: the mother’s shoulders drop, her breathing slows and her body softens. That relaxation is not incidental. It is central to why water works.

In labour, tension and fear can increase the perception of pain. When a woman feels exposed, watched, restricted or frightened, stress hormones can rise. When she feels private, warm, supported and safe, her body is more likely to produce the hormones that help labour progress, including oxytocin and endorphins.

Warm water helps by creating a quiet boundary around the mother. The pool becomes her space. The water supports her body, reduces the effort required to hold herself upright and allows her to rest between contractions. Many women describe the pool as a place where they can “go inward” and concentrate on the work of labour.

Natural pain relief without loss of control

Water immersion is widely used as a non-pharmacological method of pain relief. It does not numb the body in the way an epidural does. Instead, it helps the mother cope by reducing pressure, easing muscular tension and making it easier to find comfortable positions.

For some mothers, water reduces the need for stronger pharmacological pain relief. Cochrane’s review of water immersion during labour found that labouring in water may reduce the use of epidural or spinal analgesia, without evidence of increased adverse outcomes for mothers or babies in the trials reviewed.

This is important because many women want pain relief but do not necessarily want to lose mobility, sensation or the ability to follow their body’s instincts. Water offers a middle path: meaningful comfort while preserving freedom of movement, upright positions and active participation.

Freedom of movement: why the design of the pool matters

One of the greatest advantages of a birth pool is buoyancy. In water, the body feels lighter. The mother can shift from kneeling to squatting, leaning forward, sitting back or floating with much less effort than on land.

This freedom is not a luxury. It is part of physiological birth. Movement helps the mother respond to contractions, relieve pressure and work with the baby’s descent and rotation. Upright and forward-leaning positions may feel more instinctive than lying on a bed, particularly when the mother is trying to create space in the pelvis.

For this reason, a birth pool should not be thought of simply as a “large bath”. A good birth pool needs to be deep enough, spacious enough and shaped to allow the mother to move freely and to allow midwives to support her safely. The better the pool supports active birth, the more it can help the mother use her own instincts.

Privacy, dignity and the hormonal environment of birth

Birth is intensely personal. Many women labour best when they feel undisturbed, unobserved and secure. A pool can support this by creating a protected physical space. The sides of the pool form a natural boundary. The mother is not lying exposed on a bed. She is upright, covered by water and often more in control of how people approach her.

This sense of privacy can have real physiological value. Labour depends on oxytocin, the hormone that stimulates uterine contractions. Oxytocin flows best in conditions of safety, warmth, trust and low disturbance. A calm, respectful environment can therefore support the natural rhythm of labour.

The psychological benefits are just as important.

A woman who feels in control is more likely to experience birth as something she actively did, rather than something that was done to her. That difference can shape her memory of birth for years.

Shorter labour and fewer interventions?

Research has long suggested that water immersion during the first stage of labour may be associated with reduced use of epidural analgesia and, in some studies, shorter labour. The evidence is not identical across all studies, and outcomes depend on factors such as when the mother enters the pool, her parity, the birth setting and the support she receives.

However, the overall direction of evidence is encouraging: water immersion is a simple, low-cost intervention that can reduce reliance on more invasive forms of pain relief for many women.

When mothers need fewer interventions, maternity teams may also see wider benefits. A woman who remains mobile, comfortable and confident may be less likely to require escalation simply because she is exhausted, distressed or unable to cope.

This does not mean that water prevents complications, nor that every labour in water will be straightforward. It means that water can form part of a supportive environment that protects normal physiology whenever it is safe to do so.

What does current guidance say?

UK guidance has become increasingly supportive of water use in labour and birth. NICE recommends offering women the opportunity to labour in water for pain relief. NICE also now advises that birth in water should be considered, with discussion of the available evidence so women can make informed choices.

The 2025 NICE update is particularly important because it reviewed newer large cohort evidence on water birth during the second stage of labour. NICE concluded that, for low-risk, term, singleton pregnancies, the evidence was reassuring overall: water birth was not associated with increased risk of severe adverse maternal or neonatal outcomes and may offer benefits such as lower risk of postpartum haemorrhage, lower neonatal unit admission and lower severe perineal trauma for multiparous women. NICE also notes a small increased absolute risk of umbilical cord snapping before clamping, so careful practice and informed discussion remain essential.

This balanced message is important: water birth should not be presented as risk-free or suitable for everyone, but neither should it be dismissed as fringe or unsupported. For many healthy women with uncomplicated pregnancies, it is a reasonable, evidence-based option when supported by trained staff and safe facilities.

Is water birth safe for babies?

Parents often ask whether a baby can breathe underwater. During a properly managed water birth, the baby is born into warm water and then brought calmly to the surface. The first breath normally occurs after contact with air.

The key safety requirements are simple but essential: the baby’s head should remain submerged until birth is complete, the baby should be brought gently to the surface without traction on the cord, the water temperature should be monitored, and staff should be trained to recognise when leaving the pool is needed.

Systematic reviews of neonatal outcomes have not found definitive evidence that water birth causes harm compared with land birth, though researchers have repeatedly called for high-quality data and careful protocols. The largest recent UK cohort evidence has been reassuring for women with uncomplicated pregnancies using NHS services.

Who is water birth usually suitable for?

Eligibility varies between hospitals and countries, but water immersion is most commonly offered to women who are healthy, at term, carrying one baby in a head-down position, and expected to have a straightforward vaginal birth.

Some circumstances may mean that labouring or giving birth in water is not advised, or that the mother may be asked to leave the pool. These can include concerns about the baby’s heart rate, significant bleeding, maternal fever, heavy meconium, need for continuous monitoring, complications requiring urgent assessment, or a clinical need for interventions that cannot be safely provided in the pool.

The essential point is that water birth should be supported by clear guidelines, trained midwives, infection control procedures, safe evacuation plans and respectful communication. The mother should always understand that she can choose to leave the pool at any time, and staff may recommend leaving if clinical circumstances change.

Why the experience matters

A positive birth experience is not defined only by mode of birth. It is shaped by whether the mother felt informed, respected, safe, listened to and involved in decisions.

Qualitative research shows that women often associate water immersion with reduced pain, relaxation, privacy, control, autonomy and empowerment. Midwives also identify the importance of adequate resources, training, consistent protocols and a supportive culture.

This is where birth pools can have a profound effect. They change the room. They change the mother’s posture. They change how people approach her. They encourage quiet, patience and observation. They make it easier for birth companions to offer calm support. They remind everyone present that birth is not simply something to manage; it is something to protect.

Benefits for maternity services

For hospitals and birth centres, birth pools are a practical investment in quality of care. They are relatively simple pieces of equipment, but they can have a major impact on the environment of birth.

When used appropriately, water immersion can support:

  • greater maternal comfort and satisfaction;
  • reduced use of epidural or spinal analgesia for some women;
  • more freedom of movement and upright positioning;
  • privacy and dignity;
  • lower-intervention care for suitable mothers;
  • a calmer working environment for midwives;
  • more efficient use of staff and resources when normal birth is supported safely.

The economic argument should never overshadow the human one. The primary purpose of a birth pool is to improve care. But when better care also reduces unnecessary intervention, improves maternal experience and supports efficient maternity services, the case becomes even stronger.

Conclusion: a simple pool of water with deep benefits

A birth pool is simple, but its effects can be profound.

It offers warmth, buoyancy, privacy and freedom. It helps many mothers relax into labour, cope with contractions, move instinctively and feel more in control. It can reduce reliance on medical pain relief and support a calmer, more physiological birth environment.

For the uninitiated, water birth may seem unusual at first. But when we look at what labour requires — safety, warmth, movement, privacy, skilled support and trust — the logic becomes clear.

Water does not replace midwifery skill. It enhances it. It does not guarantee a particular kind of birth. It creates better conditions for the mother’s body to do what it is designed to do.

For many mothers, that can make the difference between simply getting through labour and experiencing birth as powerful, supported and deeply positive.

Active Birth Pools help mothers adopt upright postures to have a better experience of labour and birth

One of the clearest lessons from active birth is that labour works best when the mother is able to respond to her body. Movement, upright posture, rest, support and instinctive changes of position are not extras. They are part of the physiology of labour.

That is why Active Birth Pools are designed to help mothers use upright and forward-leaning positions in water, with the support they need to move freely, conserve energy and remain actively involved in the birth of their baby. [1]

The aim is simple: to create a birth environment that supports natural movement rather than restricting it.

Why upright positions matter

Evidence supports the value of allowing women to adopt positions that feel right to them in labour and birth. Cochrane evidence on positions in the first stage of labour found that upright and mobile positions were associated with a shorter first stage, lower use of epidural analgesia and fewer caesarean births compared with recumbent positions. [2]

Evidence on the second stage is more nuanced. Reviews have found that upright positions may reduce episiotomy and assisted vaginal birth in women without epidural analgesia, while also noting possible trade-offs such as increased second-degree tears or blood loss in some studies. For women with epidural analgesia, the evidence is less clear, and some high-quality trials have not shown the same advantage for upright positions. [3,4]

The practical conclusion is not that one position is best for every mother. It is that women should be encouraged and supported to find the positions that are most comfortable, effective and appropriate for their individual labour. [2,3]

The word upright can include many positions: standing, kneeling, supported squatting, semi-squatting, leaning forward, sitting upright, or moving between these positions as labour progresses.

For birth, squatting and kneeling positions are often described as physiological because they work with gravity and allow the mother to use her body dynamically. However, few women want or need to hold one posture continuously. Labour is rhythmic and changing. A mother may need to lean, rest, float, kneel, turn, hold, release and move again. [3]

This is why good birth pool design should not prescribe a single birth position. It should make many positions easier to use.

Why water makes movement easier

Warm water is widely recognised as an effective form of comfort and pain relief in labour. NICE recommends offering women the opportunity to labour in water for pain relief, and Cochrane evidence suggests that immersion in water during labour may reduce the use of epidural analgesia, without evidence of increased adverse outcomes for mothers or babies in the trials reviewed. [5,6]

Water changes the way the body feels. Through buoyancy, the body is supported by the water it displaces. This can reduce the strain of bearing weight, making it easier for the mother to change position, rest between contractions and explore upright or forward-leaning postures that may feel more difficult on land. [7]

For many mothers, entering the pool can bring a renewed sense of energy, privacy and focus. The water supports the body, while the pool should support movement.

Designed to support active birth

Active Birth Pools are designed around the mother in motion. The recessed handgrips, broad rounded rim, Labour Support Seat, Safety Seat and Lumbar Support are not intended to hold the mother in one position. They are there to give her more choices. [1]

She can hold the recessed handgrips for stability, lean into the wrap-around rim, rest briefly on a support seat, or use the internal features to help her move safely from one position to another. The design allows her to find what works for her body as labour changes. [1]

This matters because a poorly designed pool can restrict the very movement water birth is meant to encourage. If the mother is pushed into a semi-recumbent posture, or if the internal shape limits her ability to turn, kneel or lean forward, the pool may recreate the limitations of a bed-based birth in water.

Birth is a dynamic process. The pelvis, sacrum and soft tissues respond to posture, movement and pressure. Forward-leaning, kneeling and upright positions can help the mother create space and use gravity, while also allowing her to adjust instinctively as the baby descends and rotates. [3]

The role of the pool is to protect that freedom. It should support the mother without fixing her in place. It should make it easier for her to move when she needs to move, and easier to rest when she needs to rest.

This principle is at the heart of Active Birth Pool design.

Helping mothers conserve energy

Many women do not have the stamina to remain upright on land for long periods, especially as labour intensifies. In water, buoyancy reduces physical effort and gives the mother more ways to use upright postures without becoming exhausted. [7]

This is especially important during the later stages of labour, when the mother may need both mobility and rest. A well-designed birth pool can help her alternate between active positions and supported rest, without leaving the water or losing the benefits of warmth and buoyancy.

In this way, water can help mothers remain active for longer, not by demanding more effort, but by reducing unnecessary strain.

Designed for better births

When women are free to move, supported in water and able to follow their instincts, they are more likely to feel involved, confident and in control. This aligns with the World Health Organization’s description of a positive childbirth experience, which includes practical and emotional support, safety, dignity and a sense of personal achievement. [8]

Active Birth Pools are designed to support that experience. They help mothers use the upright and active positions natural to labour, while giving midwives access and giving partners the opportunity to remain close and supportive. [1]

The result is a pool that does more than contain water. It creates a birth environment shaped around movement, comfort, support and choice.

Conclusion

Mothers have better births when they are supported to remain active participants in labour and birth.

That is the purpose behind every Active Birth Pool: to make it easier for mothers to move freely, use upright postures, conserve energy and benefit from the comfort of warm water without being restricted by the pool itself.

Because a birth pool should not tell a mother how to give birth. It should help her listen to her body and do what comes naturally.

Why Active Birth Pools Are Especially Beneficial for Larger and Plus-Size Women

There is a subject that maternity planning does not always address openly or often enough.

Many women enter labour carrying more body weight, living with restricted mobility, experiencing pelvic or joint discomfort, or simply finding it difficult to kneel, squat, turn and remain upright for extended periods. This includes women who are described clinically as overweight or obese, women who identify as large or plus size, and women of any size whose movement is limited by pregnancy, pain, disability, fatigue or other physical factors.

These mothers may be among those who stand to gain most from the buoyancy, support and freedom of movement provided by a properly designed water birth pool.

Yet they are also among the women who may be least likely to be offered access to water during labour and birth. Research from England has found that women recorded as obese were less likely to give birth in water.[1] In some maternity services, body mass index thresholds have historically been used to restrict access, even where a woman’s individual circumstances might otherwise allow water immersion to be considered.

This deserves closer examination.

The physical reality of labour on land

Women are commonly encouraged to remain mobile and to adopt upright, forward-leaning, kneeling, side-lying or asymmetrical positions during labour. The World Health Organization recommends encouraging mobility and upright positioning during labour for women at low risk.[2] NICE also advises that upright positions and keeping mobile may be beneficial for women without an epidural during the second stage of labour.[3]

These recommendations are physiologically sound, but they can be difficult to put into practice.

For a larger woman, moving from standing to kneeling, maintaining a supported squat, turning from one side to another or getting up from the floor may require considerable muscular effort. The weight of the abdomen, pressure on the knees and hips, reduced balance, breathlessness and fatigue can all limit the positions that feel achievable.

A woman may understand the value of mobility but still be physically unable to sustain the postures that feel most natural during labour. This is not a failure of motivation. It is an environmental and ergonomic challenge.

A birthing room that offers only a bed, chair, floor mat or standard bath may unintentionally restrict the mother’s choices. When changing position becomes difficult, she may spend longer reclining or lying on the bed, not because this is instinctively right for her, but because other options are uncomfortable, exhausting or inaccessible.

Water can make freedom of movement possible when movement on land is difficult.

Buoyancy changes what the body can do

Immersion in sufficiently deep water changes the physical experience of movement.

Buoyancy partially supports the mother’s body, reducing the load placed on her muscles and weight-bearing joints. Warm water can promote relaxation, ease muscular tension and make it easier to turn, kneel, lean forward, sit, squat or float between positions.

A systematic review and meta-analysis of water immersion during labour found benefits for healthy women and their newborns and associated immersion with reduced use of several intrapartum interventions.[4] Reviews also describe warm water as supporting relaxation, comfort and easier movement between positions.[4,5]

For a woman who finds movement difficult on land, this support may be transformative.

In water, she may be able to:

  • turn without having to lift her full body weight;
  • move from sitting to kneeling with less strain;
  • lean forward while the water supports her abdomen;
  • widen or adjust her knees and hips more comfortably;
  • rock or rotate her pelvis during contractions;
  • adopt asymmetrical positions;
  • rest while remaining upright and immersed;
  • change position more frequently without exhausting herself.

The objective is not to prescribe one “correct” birthing position. It is to create an environment in which the mother can explore movement, follow her instincts and find the position that feels right at each stage of labour.

Depth is essential

Not every pool provides the same degree of buoyancy.

For water to support the body effectively, it must be deep enough for meaningful immersion. A shallow bath may provide warmth and some pain relief, but it cannot reproduce the same freedom of movement as a purpose-designed pool with adequate water depth.

Active Birth Pools typically provide a water depth of approximately 640–650 mm when filled to the specified operating level, depending on the model.[6,7] This depth allows the water to support a substantial proportion of the mother’s body when she is kneeling, sitting, squatting or leaning forward.

For larger mothers, adequate depth is particularly important. If the water level is too low, the abdomen, shoulders and upper body remain unsupported and the mother must continue carrying much of her weight through her legs, knees and arms.

The value of a birth pool is therefore not determined simply by whether it holds water. Its internal depth, dimensions, contours and support features determine how effectively the mother can use buoyancy.

Space matters too

A pool can be deep but still restrict movement if it is too narrow, too short or poorly shaped.

Larger women need sufficient internal room to turn, widen their knees, change the direction in which they are facing and move between upright, kneeling, forward-leaning and resting positions. They should not feel enclosed, wedged into one position or concerned about colliding with taps, fittings or protruding accessories.

Active Birth Pools are designed with open internal space and smooth, flowing contours. Different models accommodate different room sizes and clinical requirements, with the larger Active pool offering particularly generous internal dimensions.[6]

The absence of unnecessary obstructions allows the mother to move without continually having to negotiate equipment inside the pool.

This is an important distinction between a purpose-designed water birth pool and a large bath. The aim is not simply to contain the mother. It is to create a supportive environment for active labour.

Support should be available wherever the mother needs it

Buoyancy provides freedom, but mothers also need stable points of support.

During a contraction, a woman may want to pull, brace, lean, grip or rest. These instinctive actions can help her feel secure and in control. They are particularly valuable for women who may be less confident about their balance or who find it difficult to support their body weight without assistance.

Active Birth Pools incorporate features such as:

  • broad, rounded rims that can be held or leaned upon;
  • integrated handholds or grab rails, depending on the model;
  • submerged seats for resting while remaining immersed;
  • lumbar and body support formed by the pool’s internal contours;
  • space for forward-leaning and kneeling positions;
  • stable entry and exit arrangements.

These features allow the mother to use the pool instinctively rather than having to follow complicated instructions.

A submerged seat can provide a place to pause and recover without leaving the water. A well-positioned handhold can help her rotate her pelvis or steady herself as she moves. A curved wall can support her back or shoulders. A broad rim can support forward leaning while allowing her abdomen to remain buoyant.

This combination of freedom and support is central to the Active Birth Pools design philosophy.

Protecting dignity and reducing unnecessary assistance

Larger and less-mobile women can sometimes find themselves surrounded by additional staff whenever they need to change position, get off a bed or move to another part of the room.

Although support should always be available when required, needing several people to assist with basic movement can leave a woman feeling exposed or dependent.

Inside a well-designed pool, buoyancy may enable her to make small and large positional changes herself. The mother can respond to her contractions privately and instinctively, with the midwife nearby rather than physically directing every movement.

NICE now specifically recommends supporting women and pregnant people with mobility issues to access water during labour and birth through individualised needs assessment and reasonable adjustments.[3] This is an important recognition that restricted mobility should not automatically be treated as a reason to withhold water. In some circumstances, it may be one of the strongest reasons to make water accessible.

Health, safety and ergonomics must be designed in

For larger or less-mobile women, a well-designed pool can contribute to this safer system by enabling more self-directed movement and by reducing foreseeable demands on staff to lift, pull, hold or reposition a woman’s body weight. The aim is not “no handling” at any cost. It is to avoid unnecessary handling and to make any assistance that remains necessary planned, proportionate and safer.

An ergonomic approach asks whether the environment is compatible with the capabilities and limitations of the people who use it. In maternity care, this includes the mother, midwives, maternity support workers and any staff who may be needed in an urgent situation. Human-factors guidance emphasises improving safety through system and equipment design, rather than relying only on individuals to compensate for a poorly designed environment.[13]

The Manual Handling Operations Regulations 1992 require employers, so far as is reasonably practicable, to avoid hazardous manual handling, assess operations that cannot be avoided and reduce the risk of injury.[10,11] HSE guidance for health and social care applies this approach to the movement and support of people because poor practice can injure both the person receiving care and the staff assisting them.[12]

Health and safety is not achieved simply by asking staff to use a “good lifting technique”. It begins with the design of the task, the room, the equipment and the care pathway.

Entry and exit must be designed around real women

Access to the pool is not a minor operational detail.

For larger and plus-size mothers, and for women with pain, restricted hip or knee movement, reduced balance or fatigue, the method of entry can determine whether water immersion is genuinely accessible at all.

Why sit and swivel is especially important

Climbing a conventional step unit requires the mother to raise her centre of gravity, transfer her weight from one leg to the other and negotiate the pool wall while turning or stepping down. During labour, these movements may be made while she is tired, wet, contracting or unable to see her feet clearly.

For a larger mother, the demand on the knees, hips, pelvis and supporting leg can be greater, while the consequences of losing balance may affect both her and the staff member trying to steady her.

The Active Birth Pools sit-and-swivel method replaces climbing with a controlled sequence. The mother approaches the pool, uses the low single step where required, sits securely on the extra-wide rim, turns her body while seated, brings her legs into the pool and lowers herself into the water using the rim, recessed handrails and assistance appropriate to her assessed needs.[19,20]

Sitting before turning is the crucial ergonomic difference. Her weight is supported before she crosses the pool wall. She is not required to balance on one leg, step over a high edge or place her body weight through a midwife’s neck, shoulders or arms. The broad rim also gives her time to pause between contractions and complete each part of the movement in a controlled way.

For larger and less-mobile mothers, sit and swivel can:

  • reduce the need to climb while wet, tired or contracting;
  • avoid a high single-leg step over the pool wall;
  • lower the mother’s centre of gravity before she turns;
  • allow movement to be divided into small, controlled stages;
  • provide a stable seated pause if a contraction begins;
  • reduce the likelihood that the mother will pull heavily on a midwife for support;
  • allow assistance to be planned around the individual rather than improvised;
  • support dignity by enabling the mother to do as much of the movement as she can herself.

This is particularly important because HSE identifies active support during entry and exit, the mother’s position and the working posture of staff as sources of manual-handling risk around birthing pools.[12,20] A pool should therefore be judged not only by how comfortable it is once the mother is immersed, but by how safely and naturally she can cross its boundary.

Emergency evacuation must be anticipated in the pool design

Emergency evacuation from a birth pool is uncommon, but it must be treated as a foreseeable clinical and manual-handling task. NHS water-birth guidance commonly requires staff to know and rehearse the local evacuation procedure, and some policies specify staffing arrangements, evacuation equipment or drills.[21-23]

The safest response is not created at the moment an emergency occurs. It is created earlier through pool selection, room planning, equipment compatibility, staffing, training and rehearsal. A design that gives several practical evacuation options is safer than one that leaves the team dependent on a single difficult manoeuvre.

Active Birth Pools are designed around this reality. Their broad rim, rim-level safety seat, recessed handrails, open internal space and accessible pool perimeter can support a staged evacuation and give staff practical choices according to the mother’s condition.[20,24] The pool can also accommodate an appropriate portable hoist where the organisation’s risk assessment and procedure require one.[24]

Design features that support emergency evacuation include:

  • a rim-level safety seat that provides an intermediate supported position close to the top of the pool;
  • a broad, strong rim that can be approached from outside and used during a controlled transfer;
  • recessed handrails and support points that do not obstruct the mother or evacuation equipment;
  • generous internal space so staff can reposition the mother and place a sling or evacuation aid;
  • an uncluttered water space without protruding fittings that impede movement;
  • external access for staff, a bed or trolley and, where specified, a portable hoist;
  • a pool and room layout that allows the agreed transfer route to be practised rather than assumed.

These features are especially significant for a larger mother because an improvised manual lift carries greater potential risk to her and to staff. However, emergency-friendly design is safer for everyone. A woman of any size may become faint, exhausted, unresponsive or suddenly unable to assist. The relevant safety question is not whether staff believe they could lift a particular mother; it is whether the complete system allows the team to evacuate any mother using a planned, practised and risk-assessed method.

Better for larger women – beneficial for every woman

The design features that can make water especially valuable for larger or less-mobile women also benefit women of every shape, size and level of mobility.

A woman who is highly mobile on land can use the pool to move even more fluidly between positions. She can kneel, squat, lunge, lean forward, rotate her pelvis or float during periods of rest. The resistance of the water allows movements to be slower and more controlled, while buoyancy reduces the muscular effort required to sustain them.

A woman of average size may find that a posture she could hold for only a few minutes on land can be maintained comfortably for much longer in water.

A tired woman may rediscover movement after entering the pool. A woman experiencing pelvic discomfort may find that water allows her to open or reposition her legs more comfortably. A woman who feels vulnerable or observed may experience the pool as a private, protected space.

Inclusive design does not provide a special facility for one category of woman at the expense of another. It creates a better environment for everyone.

When a pool is deep enough for a large woman, it provides effective immersion for a smaller woman. When it is spacious enough for a woman with restricted movement to turn comfortably, it gives a more mobile woman freedom to explore a wider range of positions. When the supports are strong and well positioned, every mother can use them instinctively.

The pool itself makes a difference

Simply offering “access to water” is not enough. The design of the pool determines whether that access is meaningful.

An appropriate water birth pool should provide:

  • sufficient depth for effective buoyancy;
  • enough internal space for unrestricted movement;
  • stable support for upright and forward-leaning postures;
  • comfortable places to rest while remaining immersed;
  • secure and dignified entry and exit;
  • surfaces that support traction;
  • good access for midwives;
  • compatibility with local emergency and manual-handling procedures.

From a health-and-safety perspective, generous working space, unobstructed internal contours, accessible support points and a controlled sit-and-swivel entry method are not merely comfort features. They are ergonomic features that can reduce avoidable physical demands on the mother and the staff caring for her. Local risk assessment must still consider the complete installation, staffing model, evacuation plan and any auxiliary equipment.

Active Birth Pools have been developed specifically around these requirements. They are hospital sanitary products designed for professional maternity environments – not medical devices and not enlarged domestic baths.

Their purpose is to give mothers the space, depth, comfort and support required to remain active in water, while enabling midwives to observe and care for them effectively.

A more inclusive approach to water birth

Larger and plus-size women should not be made to feel that physiological labour, active birth or water immersion belong only to smaller, highly mobile bodies.

For some women, the benefits of water are pleasant and comforting.

For others, buoyancy may be the factor that makes upright movement, pelvic mobility and positional choice physically possible.

Maternity services should recognise this distinction. Instead of asking whether a larger woman fits a conventional model of water-birth eligibility, they should consider whether the right pool, room, assessment and support plan can meet her individual needs.

A well-designed Active Birth Pool gives larger and less-mobile mothers a better opportunity to experience comfort, autonomy, freedom of movement and the postures that may support physiological labour.

The Economic Impact of Water Birth Pools in Hospitals

Why water birth pools are a practical investment in safer, more efficient maternity care

Maternity services are under pressure to provide safer, more personalised care while making the best possible use of staff, space and budgets. In this environment, a well-designed water birth pool should not be viewed simply as an additional facility or optional extra. It should be understood as a practical investment in the quality, efficiency and resilience of maternity care.

In England, NHS hospital maternity activity remains substantial: the latest NHS maternity statistics reported 542,235 deliveries during 2024-25, with 45% of deliveries by caesarean section. At the same time, NHS England has highlighted major pressures on maternity and neonatal infrastructure, including limited space, equipment and privacy, staff wellbeing issues and a large national estate maintenance backlog.1,2

Water immersion supports physiological labour by helping mothers relax, move more freely and cope better with contractions. For many women, labouring in warm water reduces fear, increases confidence and creates a calmer birth environment. When a pool is available, suitable mothers are more likely to remain mobile, upright and actively engaged in the birth process.

The economic value of water birth pools is therefore not limited to the purchase price of the pool. The real value lies in their ability to support lower-intervention care, reduce pressure on clinical resources, improve the birth environment, protect midwives from unnecessary strain and provide a durable asset that serves the hospital for many years.

Maternity services need facilities that support efficient care

Hospitals and maternity units are being asked to deliver high-quality care in increasingly complex circumstances. Caesarean birth, induction, intervention and neonatal admission all have important clinical roles, but they also increase demand on theatres, anaesthetic teams, postnatal beds, neonatal services and midwifery time.

For women with uncomplicated pregnancies, water immersion offers a low-technology, non-pharmacological form of pain relief that can help preserve normal labour. NICE recommends offering women the opportunity to labour in water for pain relief. It also states that, when women labour in water, the temperature of the woman and the water should be monitored hourly and that the water temperature should not exceed 37.5°C.3,4

A birth pool does not replace clinical judgement, skilled midwifery care or obstetric support when needed. Instead, it gives maternity teams a practical facility that helps suitable women labour in a way that is comfortable, supported and consistent with physiological birth.

The more effectively a maternity unit can support straightforward labour for women who are clinically suitable, the more capacity it preserves for women and babies who genuinely need higher levels of care.

Reduced reliance on pharmacological pain relief

One of the clearest economic arguments for water immersion is its effect on pain management. Warm water can reduce the need for pharmacological analgesia for some women, particularly epidural analgesia. The 2018 Cochrane review concluded that water immersion during the first stage of labour probably results in fewer women having an epidural and found no evidence that labouring in water increases adverse outcomes for women or newborns, although the certainty of evidence varies across outcomes.5

Epidurals are an important and valuable option, but they require additional clinical input, monitoring, equipment and, in many cases, reduced mobility. Regional analgesia is associated with a more intensive level of observation and can affect the flow of care within the labour ward.

Water immersion provides a simple, continuous form of comfort and support. Once the pool is filled and the woman is safely assessed as suitable, the pool becomes part of the care environment. It can help mothers manage pain while remaining mobile and responsive to their bodies. This can reduce dependency on more resource-intensive forms of pain relief for women who do not need or do not want them.

For hospitals, even a modest reduction in the use of higher-cost interventions across hundreds or thousands of births can have a meaningful cumulative effect.

Supporting physiological birth and reducing avoidable intervention

A water birth pool is not just a container of warm water. When properly designed, it becomes an active birth environment.

The buoyancy of water allows mothers to change position more easily. Upright, forward-leaning and kneeling positions can be adopted with less strain. Mothers can rest between contractions, rotate their pelvis, lean, squat or float according to instinct and comfort. This freedom of movement can support the progress of labour and help mothers feel more in control.

NICE now advises clinicians to consider birth in water and to support informed choice by discussing the available evidence, including potential reductions in severe perineal trauma for multiparous women, lower postpartum haemorrhage risk, lower neonatal unit admission risk, an increased risk of snapping of the cord before clamping, and inconclusive evidence on perinatal mortality differences.6

The POOL cohort study, which examined 73,229 low-risk women using water immersion in labour across 26 UK NHS maternity services, found that waterbirth was not associated with higher risk of the study’s primary adverse maternal or neonatal outcomes compared with leaving the water before birth.7

A well-designed pool also changes the atmosphere of the room. It reduces the dominance of the bed and helps create an environment in which the mother is not positioned as a passive patient. This matters because the physical environment influences behaviour. When the room encourages movement, privacy, calm and confidence, it becomes easier to support physiological labour.

The economic implications are clear. Care that helps suitable women avoid unnecessary escalation can reduce the need for additional procedures, reduce pressure on staff and improve throughput within maternity services.

Better use of rooms, staff and clinical resources

Birth pools can improve the functionality of maternity rooms when they are integrated correctly. A pool that is easy to access, easy to clean and ergonomically designed can become a core part of the room rather than an occasional facility.

For midwives, the design of the pool has a direct effect on working conditions. Poorly designed pools can require awkward bending, overreaching, kneeling or physical support of the mother during entry and exit. Over time, these risks contribute to fatigue and musculoskeletal strain.

Active Birth Pools are designed to reduce these risks. Features such as wide rounded rims, integrated handholds, recessed surrounds, safe entry and exit, and uncluttered interiors support safer working postures and better access for care. Active Birth Pools’ own ergonomics guidance emphasises maternal freedom of movement, adequate space and depth, integrated support and protection of midwives from awkward working postures.8

Reducing manual handling risk is not only a health and safety matter. It has economic consequences. Staff injury, sickness absence, fatigue and reduced job satisfaction all carry costs. Equipment that helps midwives work safely and comfortably contributes to workforce sustainability.

Infection control and cleaning efficiency

In a busy maternity unit, a birth pool must be easy to clean thoroughly and consistently between uses. Infection control is therefore central to economic performance. NICE says baths and birthing pools should be kept clean using a protocol agreed with the local microbiology department or infection-control guidance and, for birthing pools, in accordance with the manufacturer’s guidance.9

Active Birth Pools are made from Ficore® composite and have seamless, one-piece construction. The smooth, non-porous surface and absence of unnecessary surface-mounted fittings help remove dirt traps and reduce cleaning challenges. Active Birth Pools’ cleaning guidance states that Ficore is highly resistant to disinfection, and that seamless one-piece construction and the absence of surface-mounted metalwork help deny micro-organisms the environment they need to propagate.10

This has practical benefits for hospitals. A pool that is simpler to clean can be returned to use more efficiently. It also supports compliance with local cleaning protocols, infection-control guidance and manufacturer instructions.

Cleaning time, staff time, room turnover, water safety and confidence in hygiene all affect the operational value of a birth pool. A lower-cost pool that is difficult to clean, vulnerable to surface damage or dependent on awkward fittings can become more expensive over its lifetime.

Durability, lifespan and whole-life value

The purchase price of a birth pool is only one part of the financial calculation. Hospitals should consider the full life-cycle cost: installation, maintenance, cleaning, repair, downtime, replacement and disposal.

Active Birth Pools are engineered for long-term hospital use. Ficore® composite is strong, durable, warm to the touch and resistant to damage. Active Birth Pools state that their pools are engineered to last for more than 25 years in demanding clinical environments with minimal maintenance, and that long lifespan helps reduce waste, downtime and replacement costs.11

This long lifespan changes the economics. A pool that performs reliably for decades can deliver far greater value than a cheaper product that requires regular repair, creates downtime or needs replacing after a shorter period.

Durability also supports sustainability. Long-life sanitary ware reduces waste, avoids repeated procurement cycles and helps hospitals make responsible infrastructure decisions.

The value of better birth experiences

The economic case for water birth pools is not only about direct cost avoidance. It is also about quality of care.

Women who feel calm, respected, mobile and supported during labour are more likely to describe their birth positively. A positive birth experience can influence confidence, bonding, breastfeeding and emotional recovery. For families, this matters profoundly. For hospitals, it contributes to reputation, service quality, patient satisfaction and community trust.

Maternity units are increasingly judged not only by clinical outcomes but by how women and families experience care. A high-quality water birth facility sends a clear message: the service values choice, dignity, comfort and evidence-based physiological birth.

A practical return on investment

The return on investment from a hospital-grade water birth pool can be seen in several areas:

  • reduced reliance on pharmacological pain relief for suitable women
  • better support for physiological labour
  • improved use of maternity rooms
  • shorter cleaning and turnaround processes when the pool is designed for infection control
  • reduced manual handling risk for midwives
  • fewer maintenance and replacement costs over time
  • improved maternal satisfaction and service reputation
  • a more attractive, calming and functional birth environment

These benefits accumulate over years of use. In a unit with regular demand for water immersion, a high-quality pool can quickly become one of the most cost-effective elements of the maternity environment.

Why design quality matters

Not all birth pools deliver the same economic value. A poorly designed pool can create hidden costs: difficult cleaning, awkward access, staff strain, maintenance issues, safety concerns, poor heat retention, water-management problems and shorter service life.

When assessing a birth pool, decision-makers should look beyond appearance and initial price. The key questions are:

  • Is the pool easy to clean and disinfect?
  • Does it avoid unnecessary surface-mounted fittings?
  • Does it support safe entry and exit?
  • Does it protect midwives from awkward working postures?
  • Does it allow mothers to move freely?
  • Is it made from a durable, repairable, hospital-suitable material?
  • Will it perform reliably for decades?
  • Does the manufacturer understand maternity care, infection control, manual handling and healthcare estates requirements?

Active Birth Pools are designed around these priorities. They are not adapted domestic baths. They are purpose-designed, hospital-grade sanitary ware products for maternity environments.

Water birth pools offer hospitals a rare combination of clinical, operational and economic value.

They support women to labour with greater comfort, mobility and confidence. They help midwives provide safer, more ergonomic care. They create calmer, more attractive maternity environments. They can reduce reliance on more resource-intensive forms of pain relief and support lower-intervention care for suitable women. When designed and manufactured to a high standard, they also provide exceptional long-term value.

For hospitals, the question should not be whether a water birth pool is an added cost. The better question is what value a well-designed pool can deliver over many years of daily clinical use.

A high-quality Active Birth Pool is an investment in safer care, better experiences, improved efficiency and long-term performance.

Manual Handling Risks in Water Birth Pools: Why Design Matters

A birth pool is part of the working environment

Manual handling risk in water birth pools should never be treated as an afterthought.

In a maternity unit, a birth pool is not simply a vessel for warm water. It becomes part of the working environment for midwives, part of the support system for mothers, and part of the clinical space in which care is provided.

The design of the pool therefore matters.

A well-designed water birth pool should help mothers move safely and instinctively. It should allow midwives to work close to the mother in a stable, comfortable position. It should support safe entry and exit. It should allow emergency procedures to be carried out with clarity and confidence.

Manual handling risk is not only about lifting. It is also about posture, reach, access, repetition, support, room layout and the way people are expected to move around the pool.

What creates manual handling risk around a birth pool?

Manual handling risks associated with water birth pools usually arise from four main areas:

  • the position of the mother in the pool
  • the position of the midwife while providing care
  • how the mother enters and leaves the pool
  • how staff would respond if emergency evacuation became necessary

These risks are strongly influenced by the design of the pool itself.

A pool with vertical sides, a narrow rim, obstructive fittings or poor access can make the midwife work at a distance from the mother. This may require leaning, bending, stretching or twisting during observation, reassurance, examination or hands-on support.

Over time, these repeated awkward postures can become a significant occupational-health issue.

Why vertical-sided pools create problems

Earlier water birth pools were often shaped like large domestic baths, with vertical sides and narrow rims.

The problem with this type of design is simple: the pool forms a physical barrier between the mother and the midwife.

The midwife may be forced to sit too far away from the pool, place her legs apart, lean forwards over the rim, and support herself through her arms, shoulders, neck and lower back. During a long labour this is uncomfortable. Repeated over many shifts, it becomes avoidable strain.

A narrow rim adds to the problem because it concentrates pressure into a small area of the forearm and gives the midwife less comfortable support.

This is why birth pool design should be judged not only by how it looks, but by how it works for the people who use it.

The concave shape: giving midwives room to work

Active Birth Pools were developed to solve this problem.

The distinctive concave outer profile allows the midwife to sit closer to the pool with her legs naturally positioned beneath the rim. Instead of working around a vertical wall, the midwife can get close to the mother in a more upright, balanced and supported position.

This changes the working relationship between the midwife and the pool.

The midwife can remain closer, reach less, observe more comfortably, communicate more easily and move around the pool with less obstruction.

This is not a cosmetic design feature. It is an ergonomic safety feature.

The extra-wide rounded rim

The extra-wide, bullnose-shaped rim is another important manual-handling feature.

A wide rounded rim gives mothers and midwives a broad, comfortable support surface. Mothers can use it to rest, lean, change position and support upright movement. Midwives can rest their forearms comfortably while remaining close to the pool.

The rim should also be free from unnecessary obstructions.

Taps, spouts, surface-mounted hand grips and other fittings placed on or around the rim can interfere with access. They can restrict the midwife’s movement around the pool, compromise comfort, complicate cleaning and increase the risk of accidental impact.

For this reason, Active Birth Pools are designed with a clear working edge. Plumbing and fittings are positioned to support safe use, infection prevention and freedom of movement.

Safe entry and exit

Getting into and out of the pool is one of the most important manual-handling considerations.

If a mother has to climb up steps, turn, lower herself awkwardly or rely heavily on the midwife for support, the risk increases for both mother and staff.

Active Birth Pools are designed around a simpler and safer principle: sit and swivel.

The extra-wide rounded rim allows the mother to sit securely on the side of the pool and gently swivel into the water. A small step can reduce the effective height without creating the hazards associated with larger step units.

This helps the mother remain grounded and in control. It also helps the midwife guide and reassure rather than physically support or bear the mother’s weight.

Good pool design should reduce the need for hazardous handling wherever possible.

Emergency evacuation must be designed in

Emergency evacuation is another area where pool design matters.

No pool design can replace local procedures, training, staffing or clinical judgement. But the pool should support the emergency response rather than make it harder.

Active Birth Pools are designed to give midwives practical options. The extra-wide rim, internal seats, unobstructed access and compatibility with portable hoists help staff respond according to local policy and the needs of the situation.

In some situations, the mother may be able to participate. In others, she may need more assistance. The pool, room layout and available equipment should support both routine use and emergency planning.

Emergency evacuation should never depend on improvisation. It should be considered at the specification stage.

Manual handling risk should influence procurement

When hospitals compare water birth pools, manual handling should be part of the decision-making process.

Important questions include:

  • Can the midwife get close to the mother without excessive bending or reaching?
  • Does the outer shape provide knee room?
  • Is the rim wide, rounded and comfortable to lean on?
  • Is the working edge clear of obstructions?
  • Can the mother enter and leave the pool without climbing a large step unit?
  • Does the pool support emergency evacuation procedures?
  • Can a trolley, evacuation net or portable hoist be used if required?
  • Does the pool design support cleaning, access, infection prevention and long-term safe use?

These are not minor details. They affect how the pool functions every day.

Designed to reduce avoidable strain

The safest birth pool is not simply the one that holds water. It is the one that supports the whole birth environment.

For mothers, this means easy access, freedom of movement, comfort, dignity and support.

For midwives, it means better working posture, closer access, less bending and reaching, and practical options when assistance is needed.

For hospitals, it means a pool that supports safer practice, efficient use of space, infection prevention and long-term value.

Manual handling risk can never be removed entirely from maternity care. But avoidable strain should be designed out wherever possible.

That is the principle behind Active Birth Pools.

Every curve, rim, recess, seat and support feature has a purpose: to make water birth safer, easier and more practical for the people who use it.

Sit and Swivel – the Safe Way to Enter a Water Birth Pool

All women no matter what their shape or size will find it exceptionally easy to get into our water birth pools. Mothers don’t even think about it – they move instinctively and naturally lower themselves into the water.

Why safe access begins with the design of the pool itself

Entering a water birth pool should feel simple, instinctive and secure – never like an obstacle course. For a mother in strong labour, who may be tired or less steady on her feet, the safest access method is one that reduces climbing, preserves balance and minimises the need for physical assistance.[1-4]

The Active Birth Pools solution

A compact 15 cm single step and an extra-wide, rounded rim allow the mother to step up, sit down, swivel her legs into the pool and lower herself gently into the water. The movement is grounded, controlled and familiar, with three points of contact maintained through the transfer.[1,2]

A simple movement – designed into the pool

The simple act of entering a birth pool is one of the most misunderstood aspects of water birth practice. It should never create anxiety, require awkward manoeuvres or expose the mother or midwife to avoidable risk.[1,2]

Active Birth Pools were developed with manual handling, ergonomics and safe access in mind. The design was considered with safety and manual handling expertise so that women of different shapes, sizes and fitness levels can enter with ease and with minimal need for assistance.[1,2]

Mothers do not need to climb over the pool. They sit, swivel and lower themselves into the water in one natural, fluid sequence.

How the sit-and-swivel method works

1. Step onto the compact single step. The 15 cm height advantage lowers the effective rim height of a typical 75 cm Active Birth Pool to approximately 60 cm – comparable with an ordinary bath.

2. Turn and sit securely on the broad rim. The extra-wide, rounded rim provides a comfortable, supportive surface rather than a narrow edge.

3. Swivel the legs into the water. The mother remains seated and grounded while moving her legs over the rim.

4. Lower gently into the pool. The movement can be paused and controlled, including if a contraction occurs during entry.[1,2]

Because the mother can maintain three points of contact, the transfer is more stable and less dependent on precise balance than climbing a multi-step unit, standing at height, stepping over a rim and descending into water.[2]

Why the single step makes such a difference

The single step is not intended to create a staircase. Its purpose is simply to reduce the effective height of the pool rim before the mother sits down. Used together with the wide rim, it supports a grounded transition into the water without requiring the mother to climb.[1,2]

The average Active Birth Pool height is approximately 75 cm – similar to a desk or dining table.
The 15 cm single step reduces the effective entry height to approximately 60 cm – similar to an ordinary bath.
The compact step does not dominate the poolside or prevent the midwife from moving freely around the pool.
Its small footprint helps preserve a clear working area and reduces obstruction and trip risk.[1,2]

Protecting mothers and safeguarding midwives

HSE guidance identifies manual handling risks where staff actively support a mother’s entry or exit, or where the mother uses the midwife as a support. HSE also advises that hazardous manual handling should be avoided where reasonably practicable and that unavoidable risks should be assessed and reduced.[3-6]

The sit-and-swivel method addresses the issue at source. By replacing a climb-and-step-over sequence with a seated transfer, it reduces the likelihood that a midwife will need to steady, lift, catch or become a handhold for a mother who is tired, contracting or unsteady.[2,3]

This matters because an unexpected loss of balance can place a sudden and unpredictable load through a midwife’s back, shoulder or arm. Good pool design should minimise that foreseeable people-handling risk rather than relying on staff strength or reaction.[2,3,6]

Why multi-step entry systems deserve careful scrutiny

There is a widespread assumption that a large step unit with handrails must be the safest way to enter and leave a birth pool. In practice, such systems are often required because the pool has a narrow rim or a high, straight-sided profile that cannot support a seated transfer.[1,2,7-9]

A multi-step system may look reassuring, but the whole movement sequence should be considered. A mother may need to climb, turn or reposition, step over the rim and descend into water – potentially finding a submerged floor, seat or plinth while her balance, concentration and coordination are affected by strong labour.[2]

Wet-room conditions change the risk

A birth room containing a pool is a wet clinical environment. Even with careful housekeeping, the mother may have wet feet and water may be present around the access point. Strong labour can also alter movement: a mother may pause suddenly, close her eyes, grip, squat, lean or become temporarily unable to follow a sequence of instructions.[2,10]

An access method should therefore allow her to stop safely. With sit-and-swivel entry, she can pause while seated on the rim. The risk is different if a contraction begins while she is part-way up a step unit or standing as she negotiates the pool edge.[2]

Clear space around the pool matters

A bulky step unit does not disappear after entry. If left beside the pool, it occupies working space in the area where midwives, partners and equipment need to move. If moved away, it creates another lifting, cleaning, drying and storage task.[2,7]

The compact Active Birth Pools step provides the required height advantage without obstructing the midwife’s free movement. This helps keep the poolside clearer for observation, support and emergency access.[1,2]

A warning about multi-step systems

The original Active Birth Pools article records the judgement of consulted health and safety specialists in strong terms: “The thought of wet-room conditions with mothers in strong labour climbing up a multi-step unit, stepping over a rim and down onto a submerged plinth is abhorrent.”

It also notes their concern that, when not in use, bulky step units take up space, obstruct movement around the pool and may present a trip hazard.[1,2]

The design principle is straightforward

A handrail may provide a point to hold, but it does not remove the hazards created by climbing, changing direction, stepping over a rim and descending into water. Active Birth Pools solve the access problem at design level: the broad rim is an integral, load-bearing support surface, not an accessory added to compensate for a narrow edge.[2,7-9]

The safest access strategy is not the one with the most equipment. It is the one that removes the unnecessary movement.

Questions for maternity teams and procurement leads

Can the mother sit safely and comfortably on the pool rim?
Is the rim wide and rounded enough to support sit-and-swivel entry?
Does the pool design eliminate the need for climbing?
Will the access equipment obstruct staff movement around the pool?
Where will the step unit be placed or stored when it is not in use?
Does the system add a trip, cleaning or manual handling burden?
Can midwives work close to the mother without leaning, twisting or reaching?
Is emergency access around the pool kept clear?[2-6]

Conclusion

Entering a water birth pool should be easy enough that the mother barely needs to think about it. Active Birth Pools’ extra-wide rim and compact single step support an instinctive sequence: step, sit, swivel and lower. The mother remains grounded; the midwife is less likely to become a physical support point; and the space around the pool remains clearer.[1-3]

For mothers in strong labour, for midwives working in a wet clinical environment and for hospitals seeking to reduce manual handling and trip risks, safe access should be designed into the pool from the outset.[2-6]

Smarter, Safer Design: How Our Water Birth Pools Are Evolving for Mothers and Midwives”

As there is no acceptable risk of mothers hitting their heads on protruding spouts we designed the Water Channel to safeguard them by making it impossible for them to come in contact.

If you look at the photo below you’ll see a distinctive “keyhole” shape channel set into the rim of  the pool.

We designed the  water channel to work in conjunction with wall mounted taps set well above the rim and short length spouts to prevent the risk of accident or injury.

The channel has opened up the back section of the pool so that mothers have complete freedom of movement around the pool.

Mothers can safely lean against the back of the pool and use recessed handgrips or the rounded rim for support.

When you look at other water birth pools one of the first things you notice is rim mounted metal work like taps. handgrips and controls.

These obstruct movement around pool and present  manual handling and water safety risks.

The absence of rim mounted metalwork allows mothers and midwives to move freely around the pool without risk.

Bacteria propagate on and around rim mounted fittings which increases the risk of cross infection.

Our smooth, seamless rims are free of fittings which makes them easier to clean and significantly reduces hygiene and water safety risks.

The back of the pool has been redesigned with sharper curves and wider rims to provide midwives with greater comfort, support and all-round access.

Midwives can comfortably sit on a stool like the one in this photo and move freely around the pool to attuned the mother.

In short: this seemingly simple innovation has transformed our water birth pools.  They’re safer and more user-friendly for both mothers and midwives.

Emergency Evacuation from a Water Birth Pool: A Practical Guide for Midwives

The evacuation a collapsed woman is potentially hazardous and poses risk of injury to mother and midwife.

If the need for an emergency evacuation arises the midwife should:

  1. summon help
  2. stabilise the mother
  3. turn the taps on to raise the water to rim level.

The buoyancy of the water reduces the relative weight of the mother by approximately 33% making it easier to move her and effect safe evacuation.

Midwives should float/move the mother onto a seat or support and hold her safely until help arrives.

Basics:

  1. The mother should be screened to ensure that she meets the inclusion criteria prior to entering the birth pool.
  2. Continuous risk assessment is essential to reduce the incidence of emergencies in the pool.
  3. At the first sign of a contraindication the mother should be asked to get out of the water and assisted from the pool for monitoring and care.
  4. If the mother is unable to leave the pool under her own power or has collapsed an emergency evacuation will need to be conducted.
  5. A trolley should be available
  6. for the mother to be moved onto.
  7. Care must be taken that proper lifting techniques are employed to avert strain & injury.

Example 1: Emergency evacuation utilising the labour support seat

A personal message from Founder
 and Director Keith Brainin

Dear Buyer, Midwife, Procurement Lead, Architect, Planner or Project Manager,

Choosing a water birth pool is an important decision. It should never be based on appearance or price alone.

A birth pool is a long-term clinical asset. It influences safety, hygiene, infection control, workflow, maternal comfort, midwife confidence, maintenance, installation and the overall quality of the birthing environment.

That is why proper due diligence is essential.

When you compare birth pools carefully – not simply by their initial cost, but by their design, materials, safety, usability, cleaning requirements, durability, installation process, service life and real-world performance – the right choice becomes clear.

Active Birth Pools are designed specifically for hospitals, birth centres and maternity units.

Every detail has been developed with the needs of mothers, midwives, infection control teams, manual handling teams, estates departments, procurement teams, architects and planners in mind.

When assessing any water birth pool, I encourage you to ask the questions that truly matter.

  • Is the pool easy and safe for women to enter and leave?
  • Does it support upright, active and instinctive positions during labour and birth?
  • Can midwives work comfortably around the pool without unnecessary strain?
  • Is the internal shape designed to support movement, buoyancy, rest and security?
  • Are the surfaces smooth, durable and easy to clean?
  • Are there unnecessary fittings, joints, seams or recesses that could make infection control more difficult?
  • Is the material robust enough for repeated clinical use?
  • Will the pool continue to look professional after years of service?
  • Is installation straightforward for estates teams and contractors?
  • Does the supplier have genuine experience in hospital and birth centre projects?
  • Will support be available before, during and after installation?

These are the questions that reveal the real value of a water birth pool.

A lower initial price can quickly become expensive if the product is difficult to clean, uncomfortable to use, awkward to install, poorly supported or not properly suited to the demands of a busy maternity unit.

Active Birth Pools are designed to avoid those compromises.

They combine elegant design with clinical practicality. They are comfortable for mothers, accessible for midwives, appropriate for healthcare environments and built to withstand the realities of repeated professional use.

For procurement teams, they offer long-term value.

For architects and planners, they provide a proven, attractive and practical solution for maternity room design.

For midwives, they support safe, confident, hands-on care.

For mothers, they create a calm, spacious and supportive environment for labour and birth.

Due diligence is not about choosing the cheapest option. It is about choosing the right one.

When you look closely at the design details, the materials, the user experience, the supplier’s expertise and the needs of everyone who will interact with the pool, Active Birth Pools stand apart.

I invite you to compare carefully because when you carry out proper due diligence, I believe you will see why Active Birth Pools are the logical choice.

I am always happy to help, answer questions or provide guidance at any stage of your project.

I look forward to hearing from you.

Best wishes,

The Keyword that Defines our Approach to Design is ‘Active’.

The keyword that defines our approach to design is ‘Active’.

If we look up the definition of ‘Active Birth’ we get, “Childbirth during which the mother is encouraged to move around freely and assume any position which feels comfortable”.

Founder and Director Keith Brainin spent 17 years as co-director of the Active Birth Centre in London with world famous author, educator and childbirth activist Janet Balaskas where he met water birth pioneer Michel Odent, Sheila Kitzinger and many other midwives and childbirth experts.

The knowledge and understanding gained from this formative experience has enabled us to design water birth pools that uniquely fulfil the needs of labouring women enabling them to have a better experience of labour and birth.

Freedom of movement combined with the relaxing effects of warm water and release of oxytocin significantly increases the possibility of a physiological labour and natural active birth.

We’ve spent decades observing the way that mothers move in our pools and considered how to best serve their needs.

Our passion for excellence has led us to study ergonomic design theory and to work closely with mothers, midwives, health and safety and manual handling experts.

Active Birth Pools provide optimum support for mothers in the range of upright positions natural to labour and birth.

They can hold onto the recessed handgrips or use the wrap around, bullnose-shape rim for support as the they move around the pool to explore and find the most beneficial upright positions.

Features such as the Labour Support Seat, Safety Seat and Lumbar Support create additional possibilities for mothers to explore and find the most comfortable and beneficial positions.

The design of our pools allows partners to sit in comfort and get really close to the mother.

The intimacy that couples experience with our pools is unique. No other pools allow partners to be so close without actually getting in the water.

The support thats provided both physically and emotionally has many benefits, and is key to helping mothers cope with pain and progress to experiencing physiological labour and natural birth.

Mothers simply tell us that, ‘they love our pools’.

They are actively encouraged to move freely and naturally.

They instinctively interact with the pool and find comfort and support wherever they are.

They benefit from complete freedom of movement and unparalleled comfort and therefore have greater probability of experiencing a physiological labour and having a natural active birth.

But, this is not the case with most water birth pools as renown author and educator Sheila Kitzinger OBE wrote in  ‘The clock, the bed, the chair’…

“Even a recent innovation, the birth pool, does not always permit free movement.

In theory, a pool allows a woman, supported by water, to move unencumbered.

Or so it might be thought.

Though published research often refers to mobility as an advantage of being in a pool, some pools are elaborate constructions with seats, handgrips and foot-rests, and movement in them is restricted.”

The pool dictates the position the mother should be in by placing her in a semi-recumbent posture with hand holds and foot rests to fix the arms and legs.

Mothers are positioned in the classic lying back with legs wide-open position but happen to be immersed in water.

The seats in these water birth pools are typically tilted backwards.

The mother is immobilised in a position with her pelvis tilted upwards resulting in her  pelvic outlet being up to 30% smaller.

This puts pressure on the sacrum which flexes upward, into a curved position that restricts the diameter of the pelvic outlet inhibiting the baby’s descent.

The birth canal is placed in an “uphill” orientation, forcing the mother to push upward against gravity to give birth to her  baby.

These seats and moulded fittings greatly reduce the space the mother has to move in and restricts her ability to use the positions most beneficial.

The benefits of labouring in water are largely negated.

The possibility of a physiological labour and natural birth is greatly reduced.”

Since then we have continued to innovate, improve and evolve incorporating advances in material, engineering and design.

Winner – Building Better Healthcare Awards

The Active Birth Pool has been recognised at the prestigious Building Better Healthcare Awards, receiving a “Highly Commended” accolade in the category for Best Internal Building Product.

Judges praised the exceptional quality of the pool’s design and manufacturing, describing the Active Birth Pool as highly appealing and noting the care, precision and innovation behind its development.

Designed for modern maternity units, the Active Birth Pool brings together beauty, durability, functionality and clinical practicality in one seamless, purpose-built product. Every element has been carefully considered — from the way mothers move and rest during labour, to the way midwives support, monitor and care for them.

At the heart of the design is a simple but powerful idea: the pool should support physiological labour and birth. Mothers have generous space to move freely and instinctively, with the freedom to adopt the upright, forward-leaning and supported positions that are most natural during labour.

One of the pool’s most distinctive features is its signature extra-wide rim. With broad, smooth, bull-nosed edges flowing into the sculpted skirting and down to the floor, the rim gives the Active Birth Pool its unmistakable profile.

It is also highly practical. The wide, flat surface allows mothers to lean forward comfortably on their forearms — one of the most effective positions during labour. It also provides secure support when entering or leaving the pool, while giving midwives and birth partners a stable place to lean, rest or assist.

Integrated handrails, set neatly into the rim, offer additional support for mothers in upright positions, helping them feel safe, stable and in control.

The Active Birth Pool also tackles one of the most important concerns in water birth: emergency evacuation. Built-in design features give midwives several safe options for assisting a mother from the pool, in line with Health & Safety and Manual Handling requirements.

Two standout features are the Labour Support Seat and the Safety Seat.

The Labour Support Seat has been physiologically designed to help support the mother’s pelvis and birth canal as the body prepares for a natural birth.

The rim-level Safety Seat provides a wide, comfortable platform for the mother to lean on, supports safe emergency evacuation, and allows midwives to monitor mother and baby without requiring the mother to stand or leave the water.

The pool’s seamless, one-piece construction incorporates a deeply sculpted concave skirting panel, allowing midwives to work close to the mother in comfort, with space for their legs beneath the pool.

The Active Birth Pool is manufactured in Ficore®, a proprietary composite material specially developed for high-quality baths. Ficore® was chosen to overcome many of the problems associated with conventional pool materials. It is 50% harder than acrylic and fibreglass, highly resistant to chemicals, and exceptionally durable.

Despite its strength, the surface is smooth, tactile and warm to the touch. Its high insulation value also helps the pool retain water temperature up to six times longer than standard acrylic or fibreglass birth pools.

Handmade and custom-built to order by a team with more than 95 years’ combined experience in the design and production of high-end baths, the Active Birth Pool is built to deliver decades of reliable service.

For maternity units seeking a water birth pool that combines clinical performance, comfort, safety and outstanding design, the Active Birth Pool offers a compelling first choice.

Why Birth Pool Design Matters: Sheila Kitzinger’s Advice Still Holds True

“Even a recent innovation, the birth pool, does not always permit free movement.” — Sheila Kitzinger OBE

Sheila Kitzinger was one of the most influential voices in modern childbirth. As an author, social anthropologist and birth activist, she spent decades challenging the assumption that women should labour and give birth in positions chosen for the convenience of the institution rather than the needs of the body.

In her 2003 article The Clock, the Bed, the Chair, the Pool, Kitzinger made a point that remains highly relevant for maternity units today: a birth pool should support freedom of movement — but not every pool does. [1][2]

A birth pool should not become a bed filled with water

Water immersion is often valued because it can help women feel lighter, more private, more comfortable and more able to move instinctively during labour. Evidence reviews have found that labouring in water may reduce the use of epidural analgesia, without evidence of increased adverse outcomes for mothers or babies in the studies reviewed. [3]

NICE also recognises water immersion as an option for pain relief in labour, while noting that evidence on actual birth in water continues to be assessed separately. [4]

But the benefits of water depend on the environment created by the pool itself.

A poorly designed birth pool can reproduce the same problem Kitzinger identified in beds and chairs: it can direct the mother into a fixed, semi-recumbent position. Built-in seats, moulded supports, foot rests and rigid hand grips may look reassuring, but they can also restrict the very mobility that makes water valuable in labour.

The problem with fixed seating

When a pool contains a fixed seat, it subtly instructs the mother how to use it.

Instead of inviting upright, forward-leaning, kneeling, squatting or all-fours positions, it can encourage the mother to lean back with her legs forward. In effect, the pool becomes a reclined chair under water.

That matters because maternal position affects how freely the pelvis can move. Upright and flexible positions are associated with several possible advantages in the second stage of labour when compared with supine or lithotomy positions, although the evidence varies in certainty and each position has its own benefits and considerations. [5]

Research and reviews of maternal positioning also describe how positions such as squatting, kneeling and upright postures can increase or optimise pelvic outlet dimensions compared with more horizontal positions. [6][7]

The design question is therefore simple:

Does the pool allow the mother to move — or does it decide her position for her?

Water birth works best when the mother can respond to her body

Labour is dynamic. A woman may want to lean forward during one contraction, kneel during the next, rest between contractions, hold the pool edge, float, turn, squat, or change position quickly as the baby descends.

A pool designed around freedom of movement should make these changes easy.

It should provide:

  • open internal space, rather than restrictive moulded seating;
  • comfortable support points that can be used in different positions;
  • sufficient room for the mother to turn, kneel, lean, squat and rest;
  • safe access for the midwife without compromising the mother’s privacy;
  • a design that supports physiological labour rather than imposing a posture.

The best birth pool is not simply a vessel for warm water. It is part of the clinical environment, part of the mother’s support system, and part of the midwife’s working space.

Kitzinger’s insight is still a design standard

Sheila Kitzinger’s observation was not an objection to birth pools. It was a challenge to design them properly.

A pool that restricts movement can undermine the reasons for using water in the first place. A pool that supports movement can help create the conditions that many women seek from water birth: comfort, autonomy, privacy, buoyancy and the ability to follow instinctive positions in labour.

For hospitals, architects, maternity planners and midwives, this is the key lesson:

A birth pool should never dictate the birth position. It should make movement possible.

That principle has guided the development of Active Birth Pools for decades. Our designs avoid restrictive internal mouldings and fixed birth seats because freedom of movement is not an optional feature. It is central to the purpose of water birth.

When choosing a birth pool, ask not only how it looks, but how it behaves in use.

Does it support the mother?

Does it support the midwife?

Does it preserve space, mobility and dignity?

And most importantly:

Does it allow the woman in labour to move as her body needs?

The History of Water Birth and the Development of Specially Designed Water Birth Pools

The history of water birth and the development of specialised water birth pools is a remarkable story of innovation and transformation in childbirth practices, driven by the insights of obstetrician Michel Odent and the design expertise of Keith Brainin.

Michel Odent’s groundbreaking work in the field of water birth began in the late 1970s at a state hospital near Paris.

Odent believed that childbirth had become overly medicalized and sought a more natural approach.

He introduced a pool in the hospital to ease the pain of labor, leading to some babies being born in the water.

Michel Odent with his pool in the maternity unit in Pithiviers, France

This innovative approach offered a more comfortable and less stressful birthing experience for mothers, with warm water helping to relax muscles, reduce stress, and enhance blood circulation.

Odent’s work demonstrated a reduction in the need for interventions like epidurals and episiotomies, aligning with many parents’ desires for a minimally invasive childbirth experience.

His observations and clinical experiences suggested that water birth provided a gentle transition for babies, mirroring the amniotic fluid environment​​.

“When asked about the history of birthing pools in hospitals, I mention the day when Keith Brainin realised that special bath tubs might be designed and commercialised to meet the needs of labouring women.”   Michel Odent

1989 – Sheila Kitzinger and Ethel Burns raise money to have the first specially designed water birth pool installed in an NHS Hospital at the John Radcliffe, Oxford

Building on Odent’s pioneering work, Keith Brainin, founder and director of Active Birth Pools, developed the world’s first specially designed water birth pools.

Starting in 1987, Brainin and his team focused on design, engineering, and manufacture to develop a water birth pool that excelled in quality, functionality, and durability.

Judges at the Building Better Healthcare Awards said that, “Active Birth Pools are the pinnacle of water birth pool design and development – an incomparable combination of design, materials and manufacturing” 

The Active Birth Pool was designed with ergonomic principles to support natural childbirth postures and provide comfort for the mother.

Features like extra-wide rims, integrated handrails, and specially designed labor support and safety seats were included to enhance safety and functionality.

The use of Ficore composite for construction ensured a harder, more chemical-resistant, and warm-to-the-touch surface that retains heat efficiently.

Keith Brainin with Sheena Byrom and midwives in the Lotus Birth Centre, Royal London Hospital 2018

Additionally, the pools were equipped with features like chromotherapy LED lighting and Bluetooth sound systems, allowing mothers to personalize their birthing environment.

These innovations in water birth pool design have significantly contributed to the safety, comfort, and natural approach to childbirth​​.

Both Michel Odent’s clinical insights and Keith Brainin’s design innovations have played a crucial role in transforming childbirth practices, emphasizing the importance of a natural, holistic approach to labor and delivery.

Their contributions have been instrumental in making water birth a viable and increasingly popular option for expectant mothers worldwide.

Multi-Colour Chromotherapy LED Lighting and Bluetooth Sound

A calm, soothing atmosphere can help reduce stress and anxiety, allowing mothers to relax more deeply and support the natural flow of physiological labour.

By integrating multi-colour chromotherapy LED lighting and Bluetooth sound into our birth pools, we’ve created an environment where sensory comfort plays a central role in promoting safe, gentle births.

Our advanced LED lighting system features six tranquil colours, casting a soft ambient glow throughout the room and within the pool itself.

Midwives can see much more clearly into the pool enabling them to monitor the situation more easily and effectively without intruding on the mother.

Complementing chromotherapy lighting is a fully integrated Bluetooth sound system that has been specially developed for our water birth pools

With two premium built in speakers mothers can wirelessly connect to play music making the ambiance of the room more personal and conducive to labour.

Our light and sound systems can be supplied in both 230 and 120 volts (USA).

The Design Philosophy Behind Active Birth Pools

In the world of industrial design, few principles have stood the test of time like those set forth by Dieter Rams. Among his “Ten Principles of Good Design,” one stands out for its quiet power and enduring relevance: “Good design is as little design as possible.” This idea champions simplicity, honesty, and restraint—a philosophy that aligns perfectly with the ethos behind Active Birth Pools.

At Active Birth Pools, we design water birth pools not just as products, but as environments. Our pools support one of life’s most natural and transformative events: childbirth. This is not a time or place for gimmicks, clutter, or over-engineering. Instead, our focus is on creating objects that are intuitive, purposeful, and deeply respectful of the experience they’re designed to serve.

Form Follows Function—And Empathy

When we say “as little design as possible,” we’re not talking about doing less. We’re talking about doing only what’s essential—and doing it beautifully. Every curve, surface, and contour of an Active Birth Pool is there for a reason. There is no ornamentation, no unnecessary elements added to make a statement. The pool’s elegant, organic form is shaped entirely by the physiological needs of women in labour and the practical requirements of midwives and clinical staff.

The result is a design that feels as natural as the process it supports. It invites instinctive use and makes sense without explanation. This is design that understands the moment and quietly serves it.

Design That Disappears Into the Experience

Our goal is not to impress with visible complexity but to enable a powerful experience through simplicity. When a woman enters an Active Birth Pool, she shouldn’t be thinking about the product; she should be free to focus entirely on herself and her baby. The pool becomes part of the background—supportive, safe, unobtrusive. It’s not a showpiece; it’s a silent partner in birth.

This kind of “invisible” design is only possible when everything unnecessary is stripped away. What remains is the essence—a sculptural yet practical space that feels calm, grounded, and purposeful.

Integrated, Not Added-On

Good design does not bolt on features. It integrates them. At Active Birth Pools, every element—whether it’s a hand grip, step, or recessed area for medical access—is part of the form itself. There are no visible seams, fixtures, or accessories that suggest improvisation. Everything flows together in a unified whole, contributing to both safety and aesthetics.

This seamless integration also supports infection control and long-term durability—crucial factors in hospital environments. But more than that, it’s a commitment to clarity and coherence in design.

Material Honesty and Tactile Comfort

We select materials not just for their performance but for their sensory qualities. The finish of our pools is smooth, warm, and inviting to the touch. It’s easy to clean, gentle against the skin, and psychologically comforting—a key consideration for women in labour.

This is another way we practice “as little design as possible.” We let the materials speak for themselves, choosing those that support the function and the feeling without the need for artificial textures or decorative layering.

Quiet Confidence in a Clinical World

In hospital settings, design can often be sterile or overbearing. By contrast, Active Birth Pools offer a quiet confidence. Their presence in a room is understated yet reassuring. They don’t try to dominate the space; they help define it with dignity and grace.

This sense of calm and order is not just aesthetic—it’s functional. A well-designed pool reduces stress, supports natural movement, and allows midwives to work more effectively. In this way, minimal design becomes a powerful tool for improving outcomes.

Conclusion: Less, But Better

At its core, “good design is as little design as possible” is about restraint, intention, and clarity. It’s about stripping away the noise to let the true purpose shine through. This philosophy is not a style—it’s a discipline. And it’s one we practice daily at Active Birth Pools.

By honouring the principle of minimal design, we’ve created birth pools that are not only clinically superior and user-friendly, but emotionally supportive and deeply human. In a world of overdesigned solutions, our pools stand as a quiet reminder: sometimes, the best design is the one you don’t notice at all.

Key performance metrics for hospital grade water birth pools

Water birth pools specially designed to give midwives superior safety, comfort and support

2016 – Launch of the Water Birth Safety Initiative

Hospitals in the United Kingdom began allowing women to use specially designed pools of water for labour and birth during the 1980’s.

The wide-spread popularity and acceptance of water birth pools as a standard part of the maternity care package necessitated the development of guidelines & regulations to define standards and ensure they’re met.

The United Kingdom Department of Health has published a panoply of water safety directives that apply to water birth pools.

Policies and recommendations set forth in the Water Birth Safety Initiative are based upon these publications.

The Water Birth Safety Initiative (WBSI) calls for development of international standards modelled on the UK’s so that women the world over can benefit from the use of water for labour and birth safeguarded from risk.

The WBSI calls for the implementation of stricter protocols and sets forth recommendations for equipment standards.

The guidelines set forth in the WBSI are intended to serve as a framework of standards for birth pool suppliers, hospitals and midwives to work with to establish  safe codes of practice.

Guidelines for Water Birth Pools Installed in Hospital

Water is more prone to bacteria growth after it leaves the public water distribution system and enters a building’s plumbing.

There it finds warmer temperatures, stagnation, and smaller pipes, valves and fittings.

Biofilm that forms on valves and fittings and pipe walls not only feeds bacteria but also protects them from the hot water and chlorine that typically would kill free-floating organisms.

Large systems with complex piping networks — like those found in hospitals, hotels and large apartment buildings — are especially prone to bacteria growth.15

Water Birth Pools that are installed in hospitals have the benefit of being maintained by staff to ensure that protocols are established, met and maintained.

Consideration and due diligence with regard to the prospective purchase of water birth pools and the assessment of pools already in use needs to be taken to ensure that the associated plumbing and electrical systems meet relevant safety standards.

The United Kingdom’s Department of Health and National Health Service has an exemplary safety record achieved by establishing rigorous sets of guidelines and regulations for the design, installation, use and maintenance (cleaning/disinfection) of water birth pools.

In the UK water birth pools are classed as a Category Fluid 5 water risk which represents a serious health hazard due to the concentration of pathogenic organisms, radioactive or very toxic substances, e.g. containing faecal material or other human waste; butchery or other animal waste or pathogens.

Water Birth Pools must be installed in compliance with water regulations as set forth in The Water Supply (Water Fittings) Regulations 1999.11

The 7 sins of water safety

To ensure high standards are met it is strongly advised that you do not use a water birth pool that has any of these features:

  1. Overflow drains
  2. Internal water inlets
  3. Hand-held showers
  4. Systems with flexible hoses or extended pipes
  5. Integral or secondary plumbing systems
  6. Any type of recirculating or pumped water systems such as whirlpool, jacuzzi, spa, bubbling, filtering etc
  7. Heating systems

1) Overflow drains

Overflow drains harbour bacteria and can serve as a conduit for cross infection.

Regulations are very clear on this point – overflow drains should not be installed on water birth pools as they constitute a constant infection control risk much more significant than the possible risk of damage due to water overflowing.11,12

Some digital taps on the market can be set for filling time thus obviating the risk of the pool overflowing.

2) Internal water inlets

Internal water inlets act in place of taps to fill the pool.

They are installed on the inside of the pool just above the water line and connected with pipework to a thermostatic valve.

If the water level rises there is a high risk of back flow enabling bacteria to enter the system creating a risk of cross infection.7

3) Handheld showers

Handheld showers present a significant infection control risk due to the fact that they can fall in the pool and be contaminated with bacteria that could breed and be passed on next time the shower is used.

Department of Health regulations clearly stipulate that handheld showers and bath/shower mixers are not installed for use with water birth pools. 13

Handheld showers present a Fluid Category 5 risk to the mains water supply.

It must not be possible to submerge the showerhead in the water due to risk of cross infection.

In order to comply with category 5 water regulations covering back siphonage, a class AUK3 air gap would be required, which generally prevents the use of handsets, unless there is a separate break tank installed in the hospital plumbing system.

4) Systems with flexible hoses or extended pipes

Systems that employ flexible piping, have branch pipes or hold stagnant water present a potential hazard and must not be used with water birth pools.

It is impossible to clean, disinfect or monitor these systems.

They have been proven to be a source of Legionella and Pseudomonas. 14

Weekly flushing recommendations recommended by the department of health cannot be executed with such systems, and the effectiveness of this cannot be monitored due to the inacessibility of the closed system.

5) Integral or secondary plumbing systems

Integral, secondary or proprietary plumbing systems are fitted to some water birth pools.

As these systems can employ flexible and non-flexible piping, overflow drains, handheld showers and are often pumped or recirculating they present a significant infection control risk and should be banned from use.

Regulations stipulate that water birth pools are filled from thermostatically controlled wall mounted mixer taps plumbed directly into the hospitals water supply with the minimum of pipework.

Not only do secondary or integral plumbing systems present unacceptable risks, they are impossible to clean, disinfect or monitor and therefore present an extremely high and unacceptable infection control risk.

They must not be present on pools used for labour and birth. 10

6) Recirculating or pumped water systems

Recirculating or pumped water systems such as whirlpool, jacuzzi, spa, bubbling, filtering etc. have the perfect environmental conditions to be a potential source for the growth of microorganisms, including legionella bacteria and must not be installed on water birth pools.

Water systems that are able produce aerosols represent the highest levels of risk.

Aerosols can be generated very easily when the water surface is broken -for example, by falling water droplets, splashing, or by bubbles breaking at the surface.

Once introduced to artificial water systems, Legionella can thrive in warm water (30 – 35 °C) and has been shown to be present on flexible seals and metal surfaces within plumbing systems used in domestic potable water supplies.

Inadequately maintained spa pools (birth pools with pumped or recirculating systems) provide ideal conditions to support the growth of legionellae and other microorganisms, which may then become aerosolised and subsequently inhaled.15


7) Heating systems

Heating systems for water birth pools are not necessary and present unacceptable infection control risks.7

There are two types of heating systems in use:

1. Recirculating system with a heat exchanger

Water is pumped out of the pool and through a heat exchanger and then flows back into the pool.

These systems present one of the highest infection control risks and should not be installed on a water birth pool under any circumstances. (covered by points 4, 5 and 6 above).

2. Electric heating systems

Similar to under floor heating found in homes do not present an infection control risk.

But, they do present an unacceptable health and safety risk and should therefore not be installed in water birth pools.

These systems consist of a network of cables embedded in the fabric of the birth pool that are attached to the power supply through a thermostat.

The heat is transmitted from the cables through the floor of the pool and then transferred to the water.

The inherent problem with these systems is that the water is relied on to take the heat away from the material.

If a woman remains motionless the heat becomes concentrated and a “hotspot” develops which can result in the woman being burned.

Recommendations

Plumbing for filling and emptying water birth pools should be simple, straight forward and kept to the minimum.

A set of taps (see below) mounted on the wall 15cm above the rim and a drainage system similar to that of a normal bath is all that is required.

Rim mounted taps present two areas of risk:

1. Women may hit their head on taps that are mounted on the rim of the pool causing injury.

In the throes of labour a woman is not as cognisant of her surroundings as she normally is.

She needs to be protected from the potential harm that could result from hitting her head or other part of her body on the spout.

2. Risk to the taps and pool caused by the labouring woman grabbing onto the spout for support could easily cause damage to the fitting or fabric of the pool.

Filling the birth pool

Water Birth Pools should be filled directly from the hospitals main water supply through a ¾ Thermostatic Mixing Valve (TMV).

To comply with UK National Health Service regulations the valve must have TMV3 approval for use in Healthcare and Commercial situations and certify that it conforms to the performance requirements of the Department of Health.16

To kill legionella and other bacteria, water in hospitals systems is heated to 60 – 80 °C.

Water temperature entering the birth pool should be limited by the TMV to 44 °C to prevent scalding.

The added benefit of using a TMV connected directly to the hospitals main water supply is that it can be set to automatically flush itself of stagnant water twice a day and be thermally disinfected periodically.

dsc_2965

The use of a TMV ensures a safe water supply.

Digital thermostatic mixing valves with enhanced thermal performance that incorporate these features are ideal:

1) Programmable control to accurately mix and maintain the temperature of the water flowing into the birth pool and limit the temperature of the water to 44 °C to prevent scalding.17

2) Programmable fill duration to fill the pool to the desired depth and then turn off.

This is important as water birth pools are not allowed to have overflow drains installed and this feature will prevent the pool from overflowing when unattended.

3) Programmable duty flushing to ensure that water does not stagnate within the tap and associated pipe work, effectively controlling the multiplication of legionella & other bacteria in infrequently used outlets.

Flushing duration is in line with HSE L8 recommendations.18

4) Programmable high-temperature thermal disinfection to destroy the proteins in viruses and bacteria and render them as dead or inert.

Thermal disinfection works by achieving a moist heat which is set at a specific temperature for a set amount of time.

Viruses and bacteria are very sensitive to heat and they will die if exposed to higher temperatures. 19

Emptying the Pool

Water from a birth pool needs to be treated as Fluid category 5 waste representing a serious health hazard due to the concentration of pathogenic organisms derived from fecal material or other human waste and emptied directly into the hospital’s waste water system.20

The pipework needs to have a trap or U bend fit as close to the waste/drain as possible.

The drainage fitting or waste should seal neatly into the drain.

The drainage fitting should be cleaned and flushed through with disinfectant and then dried as part of the cleaning protocol.

The waste should be kept closed when the pool is not in use.

There should be NO flexible pipe used in the drainage pipework.21

The waste should be remotely operated (i.e. pop up waste with rim mounted control) and of the best quality, preferably high-grade brass, to resist the corrosive action of chlorides and other disinfectants.

DSC_2915

The Water Birth Safety Initiative was conceived by Keith Brainin to motivate and enable birth pool suppliers and health care professionals to raise standards and implement protocols to make water birth safe.
