In healthcare construction, some of the most critical spaces are also the least glamorous. Plant rooms are engineered with precision. Operating theatres receive forensic attention. Patient bedrooms are designed with hospitality in mind.
And then there is the sluice room.
Often treated as a secondary consideration, squeezed into leftover space or revisited late in the build programme, the sluice room is in fact one of the most important infection control environments in any hospital. When designed properly from the very outset, it protects patients, safeguards staff, supports compliance, and prevents costly redesigns at commissioning stage.
When treated as an afterthought, it can jeopardise CQC sign-off, disrupt workflow, increase infection risk, and require expensive remedial work.
For contractors, designers, and developers working in healthcare environments, the message is clear: sluice room design must be integrated at concept stage and not retrofitted when space is already constrained.
Successful integration of compliant, efficient sluice room design in hospital builds requires careful consideration of workflow, mandatory equipment, materials, utilities, and regulatory requirements.
Why the sluice room deserves
early-stage design attention
The sluice room is the controlled environment where human waste is disposed of safely and where reusable items such as bedpans are cleaned and disinfected.
From an infection control perspective, it is a high-risk zone. Poor layout, incorrect material specification, or inadequate utilities can compromise the separation between clean and dirty processes, creating potential cross-contamination.
While sluice rooms represent a small part of a healthcare build, they often carry the most compliance risks. Contractors must navigate multiple regulations and requirements, such as:
n Health Building Notes (HBN) — specifically HBN 00-09 regarding the built environment.
A building’s design can help infection prevention and control (IPC) by providing an environment that is easy to clean and maintain. This document highlights the major IPC issues and risks to address to achieve designed-in IPC.
n Health Technical Memoranda (HTM) — particularly HTM 01-01.
The HTM 01-01 consists of a list of documents from Parts A-E, which provide guidance and information on the management and decontamination of reusable surgical instruments used within healthcare. Part D of 01-01 specifically focuses on Washer Disinfectors.
n Water Regulations Approval Scheme (WRAS) — critical for backflow prevention.
WRAS is an independent UK certification body that rigorously tests plumbing products and materials, helping businesses and consumers meet regulations to keep our water safe.
n The Health and Social Care Act 2008.
Code of practice on the prevention and control of infections and related guidance — this is key guidance to follow to keep patients, residents and staff safe from infections.
n CQC — fundamental requirements for safety and hygiene.
The CQC is the independent regulator, ensuring hospitals and GP practices provide safe, high-quality, and compassionate care. It monitors, inspects, and rates services, and acts if these services are not met.
Failure to provide these core elements, or to position them in a way that supports correct infection control workflow, can delay or prevent final sign-off.
For contractors and developers, that risk translates into project overruns, rework, reputational damage, and unplanned costs.
The solution is simple in principle: design it correctly from the beginning.
Mandatory equipment:
designing for compliance
When designing a sluice room, there are fundamental items which must be included without fail to meet minimum equipment and hygiene standards set by CQC regulators. These must not only be present, but they must also be positioned and serviced correctly. The three crucial pieces of equipment which must be present in a compliant sluice room are:
1. Bedpan Washer Disinfector or alternative human waste disposal method
The Bedpan Washer Disinfector is the central piece of equipment within the sluice room. It ensures that bedpans and urinals are thoroughly cleaned and decontaminated. By automating this process, it reduces the risk of infection, protects healthcare staff, and maintains strict Infection prevention standards. Operating with high temperatures to decontaminate with steam it delivers consistent, safe, and efficient disinfection, making it a central tool in patient care and infection control.
To install and operate the machine correctly it requires:
n Cold water supply.
n Drainage installed with appropriate falls and gradients.
n Electrical supply.
Designers must consult manufacturer technical data at early stage to confirm service requirements, dimensions, and clearance zones. Crucially, the machine’s position influences the entire layout. Services cannot simply be ‘brought in later’ without consequence to suitability or project costs.
2. Dedicated hand wash basin
A clinical hand wash basin is a compulsory item to include within a sluice room. It must:
n Be separate from any manual sluice or janitorial sink combination and for the sole use of Hand washing only.
n Include appropriate splashback protection.
n Support hands-free operation where required.
n Be in support of correct workflow.
Its position is strategic. Staff should wash hands immediately after handling contaminated items and again before leaving the room. Placing the basin behind the washer or in a corner that forces backtracking undermines infection control practice
3. Racking and storage for clean, ready to use utensils
Appropriate storage racks are required for clean bedpans and utensils. These racks should:
n Be clearly segregated from dirty processes.
n Be made from wipeable, corrosion-resistant, stainless-steel material.
n Allow air circulation where necessary.
n Be mounted securely to prevent movement.
Proper racking and storage are essential. They establish and maintain the integrity of the clean zone, supporting infection control, workflow, and patient safety.
Materials matter: specifying for
durability and hygiene
Sluice rooms operate in high-moisture, high-use environments. Material specification is not an aesthetic decision; it is a hygiene and lifecycle decision.
n Why stainless steel is recommended
Stainless steel is widely recommended for healthcare environments due to:
n Corrosion resistance.
n Non-porous surface.
n Ease of cleaning.
n Durability under chemical exposure.
n Long lifecycle performance.
Unlike coated metals or lower-grade materials, stainless steel does not rust or degrade when exposed to aggressive cleaning agents. It withstands thermal disinfection processes and regular wipe-down protocols.
When specifying sinks, worktops, racking and cabinetry, contractors should prioritise healthcare-grade stainless steel solutions.
n Wall and floor finishes
Other material considerations include:
n Seamless, coved flooring to eliminate dirt traps.
n Impervious wall cladding.
n Hygienic junction detailing.
n Slip-resistant finishes.
Selecting domestic-grade finishes for a healthcare sluice is a false economy.
The cost of retrofitting vs designing
from the start
Sluice rooms are often compromised because spatial allowances are made late in the process. By the time mechanical and electrical services are fixed, walls are up, and plumbing routes are defined, relocating utilities to accommodate compliant equipment becomes expensive and disruptive.
Common late-stage problems include:
n Insufficient drainage capacity for a washer disinfector.
n No dedicated hot and cold water supplies in the correct location.
n Electrical points positioned incorrectly for equipment layout.
n Inadequate space to maintain clean/dirty segregation.
n No clear handwash provision within workflow.
At that stage, contractors may be forced to reconfigure walls or reroute services, none of which are ideal.
Conversely, when sluice rooms are considered at RIBA Stage 2—3 (or equivalent concept and developed design stages), the correct footprint, drainage falls, ventilation requirements, and service points can be integrated seamlessly.
Early planning ensures:
n Proper infection control zoning.
n Efficient staff workflow.
n Compliance confidence.
n Lower lifecycle maintenance costs.
n Faster regulatory approval.
In short, early integration protects the project and the budget.
Designing around workflow:
clean and dirty separation
The single most important principle in sluice room design is workflow.
The space must enable a logical progression from dirty to clean, without crossover. Contractors and designers should think in terms of directional flow.
A typical compliant workflow includes:
1. Entry with contaminated items (e.g. bedpans, urine bottles).
2. Disposal of waste.
3. Mechanical washing and thermal disinfection via a Bedpan Washer Disinfector.
4. Removal of clean items to designated clean storage.
5. Hand hygiene before exit.
If clean items pass through dirty zones, or if staff cross contaminated areas to reach handwashing facilities, the design fails from an infection control standpoint.
Layout considerations
At design stage, you must ensure your concept design considers:
n Positioning the bedpan washer on the ‘dirty’ side of the room.
n Installing racking for clean items away from the waste disposal area.
n Ensuring the hand wash basin is accessible at point of exit.
n Avoiding dead-end corners that accumulate contamination.
n Allowing sufficient circulation space for safe handling.
It is also important to remember that even in sluice rooms that have limited space and offer compact layouts, clear zoning must be maintained.
Utilities: the invisible infrastructure
that defines the layout
Mechanical and electrical services are often what constrain late stage design flexibility.
In sluice rooms, utilities dictate the room’s logic. It is important to give proper consideration and intentional planning to the following compulsory prerequisites:
n Water supply
Bedpan Washer Disinfectors require specific water pressure and temperature supply. Positioning the water feed incorrectly may:
n Restrict machine placement.
n Create awkward hose runs.
n Interfere with workflow.
n Complicate maintenance access.
Bringing services in at the wrong wall can force layout compromises.
n Drainage
Drainage falls are critical. Poorly positioned waste outlets can result in:
n Backflow risk.
n Standing water.
n Odour issues.
n Non-compliance.
Drainage should be designed with equipment placement confirmed and not guessed.
n Electrical supply
Dedicated electrical circuits are often required. Consider:
n Proximity to water sources.
n IP ratings.
n Maintenance access.
n Isolation switches.
Electrical points positioned without reference to final layout can disrupt clean/dirty zoning.
n Ventilation
Sluice rooms generate humidity and odour. Proper extraction is essential to maintain negative pressure where required to ensure air-borne bacteria does not enter other areas. Again, this must be engineered early.
n Location within the building: strategic positioning
Beyond internal layout, the room’s position within the wider facility matters. Consider:
n Proximity to patient bedrooms or wards.
n Accessibility for staff without crossing public areas.
n Separation from kitchens or clean utility rooms.
n Noise control from Bedpan Washer Disinfector operation.
Poor location planning can lead to operational inefficiencies long after handover.
Compliance and CQC sign-off:
avoiding costly delays
The CQC assesses whether environments are safe, clean and suitable for purpose. While CQC does not design buildings, inspectors expect facilities to meet recognised infection prevention standards.
A non-compliant sluice room can result in:
n Requirement notices.
n Delayed occupancy.
n Reputational damage.
n Expensive remedial works.
Common compliance failures include:
n In operable layout.
n No dedicated hand wash basin.
n Inadequate space for separation.
n Domestic-grade finishes.
n Poorly maintained or incorrectly installed Bedpan Washer Disinfectors.
n Lack of ventilation.
For developers working to tight commercial timelines, failing inspection due to preventable design oversights is entirely avoidable.
Early collaboration with infection control advisors, equipment suppliers, and specialists, mitigates this risk.
Engaging specialists at design stage
Sluice room specialists understand the spatial and service implications of equipment selection. Engaging the services of our specialists early can provide you with:
n Accurate room planning: ensuring every piece of equipment fits seamlessly while maintaining accessibility and safety.
n Confirmed service requirements so plumbing, electrical, and drainage needs are identified and integrated from the outset.
n Workflow-optimised layouts designed to minimise staff movement, reduce contamination risk, and streamline daily operations.
n Clear compliance alignment guaranteeing that all installations meet current healthcare and regulatory standards.
n Reduced redesign risk saving time, cost, and frustration by avoiding last-minute changes during construction or refurbishment.
Waiting until procurement stage removes flexibility and limits options.
The operational perspective:
designing for staff efficiency
A well-designed sluice room is not just about passing inspections; it is about making life easier for the staff who use it every day and the safety of the residents and patients. An efficient layout:
n Reduces unnecessary movement.
n Minimises manual handling risks.
n Speeds up turnaround times, which allows for more time dedicated to patient care.
n Encourages correct hygiene practices.
When a room is poorly designed, staff are forced to improvise. Improvisation leads to shortcuts, and shortcuts increase the risk of infection. To avoid this, construction teams should observe clinical workflows during the design phase, gaining insight into how the space will actually be used.
Lifecycle thinking: beyond initial
installation and planning for the
long term
When selecting equipment, it is important to think beyond the initial installation. A sluice room should be designed not just for day-one functionality, but for years of safe, efficient use. Consider factors such as durability, ease of maintenance, and adaptability over time. Ask questions like:
n Can the bedpan washer or other equipment be serviced without tearing down walls?
n Are valves, isolation points, and service connections easily accessible?
n Will the materials stand up to repeated exposure to cleaning products over a decade or more?
n Is there flexibility to replace or upgrade equipment as technology or clinical needs evolve?
By planning with the full lifecycle in mind, you reduce future disruptions, avoid costly retrofits, and ensure the room continues to support staff and patient safety for years to come.
Designing only for day-one compliance is short-sighted. Designing for lifecycle resilience protects the client’s investment.
The commercial case for early planning
Planning sluice rooms early is not just good practice; it makes financial and operational sense. Early integration can:
n Reduce costly changes and redesigns.
n Streamline commissioning and handover.
n Lower overall project risk.
n Help contractors demonstrate proactive infection control.
In competitive tenders, showing that you understand how the room will actually function (and not just what the drawings say) can set your bid apart. Today’s healthcare clients expect contractors to appreciate operational realities, ensuring the facility works efficiently from day one.
Elevating the status of the sluice room
Infection prevention begins with environment. The sluice room may be out of sight to patients, but it is central to safe care delivery. For contractors, architects, and developers working in hospitals, the lesson is clear: do not leave sluice room design to the end.
Integrate it at concept stage. Plan the workflow. Confirm utilities early. Specify robust materials. Install mandatory equipment correctly. Design for compliance, durability, and efficiency.
When the sluice room works properly, no one notices. When it does not work properly, everyone does.
By proactively addressing the design of a sluice room within the planning stage of a hospital build, you can be sure you are delivering a compliant build that exceeds your clients’ expectations and safeguards the long-term operation within the facility, and provides a foundation which, with the appropriate ongoing maintenance, will aid infection prevention and control for many years.
