Designing toilet cubicles for your commercial space that not only cater to the diverse needs of multiple users, but also adhere to building regulations can be a complex challenge. Toilet cubicle dimensions, materials and accessibility play a pivotal role in ensuring not only comfort but most importantly compliance. 

At North East Toilet Cubicles, we have been working in the commercial sector for over a decade, providing safe toilet cubicle solutions to a range of different industries from the retail sector to hospitality. In this comprehensive guide, we delve into the intricacies of toilet cubicle dimensions, exploring the various regulations and guidelines that govern their design. By discussing the requirements for different cubicle types, we aim to equip you with the knowledge necessary to create inclusive and functional washroom spaces.


Building Regulations and Standards

Toilet cubicle dimensions are primarily governed by two key regulations in the UK: the Building Regulations Part M and the Equality Act 2010. These regulations provide guidance on the minimum standards for accessibility, ensuring that washrooms cater to individuals with varying abilities and mobility levels.

  • The Building Regulations Part M: The Building Regulations Part M outlines specific requirements for toilet cubicle dimensions, manoeuvring spaces, door widths, and grab rail placements. Compliance with these regulations is mandatory for new constructions and major renovations.
  • The Equality Act 2010: The Equality Act 2010 reinforces the principles of inclusivity and non-discrimination, emphasising the need for accessible facilities in public spaces. By adhering to these regulations, you can create washrooms that promote equal access and dignity for all users.


Standard Toilet Cubicle Dimensions

The foundation of any washroom design lies in the standard toilet cubicle dimensions. 

  • Diameter: According to Building Regulations, all standard cubicles must have a minimum manoeuvring space of 450mm in diameter within the cubicle. 
  • Width: The recommended internal width for a standard cubicle is typically 800mm, with a depth of 1500mm. However, these dimensions are often exceeded to enhance user comfort and accommodate design preferences.
  • Doors: Inward-opening doors are common in standard cubicles, with an opening width of approximately 600mm. It’s crucial to consider the door swing direction and clearance to prevent obstructions and ensure smooth access.


Ambulant Disabled Toilet Cubicle Dimensions

Every washroom should feature at least one toilet cubicle suitable for ambulant disabled users. If a washroom contains only a single cubicle, it must be designed to accommodate ambulant disabled individuals.

The standard dimensions for an ambulant disabled cubicle are 850mm wide and 1500mm deep, with a minimum width of 800mm between surfaces. These cubicles must incorporate an outward-opening door and grab rails installed along the sides for additional support.


Wheelchair Accessible Toilet Room Dimensions

Catering to individuals with wheelchairs or significant mobility challenges requires dedicated wheelchair-accessible toilet rooms. These rooms have undergone recent modifications to accommodate an overall cubicle length of 2220mm, an increase from the previous standard of 2000mm.

The door opening for a wheelchair-accessible toilet room must be 900mm wide, with an outward-opening door measuring 950mm in width. These dimensions ensure ample space for wheelchair users to manoeuvre and transfer comfortably.

When installing IPS (Integrated Plumbing System) panel systems to conceal the toilet cistern, it’s crucial to maintain the required dimensions of 2200mm x 1500mm, prioritising user accessibility over the installation of IPS duct sets.


Cubicle Configuration and Layouts

In addition to cubicle dimensions, the configuration and layout of cubicles within a washroom play a significant role in overall accessibility and functionality. 

Common configurations include:

  • Enclosed: Cubicles situated between walls.
  • Corner: Cubicles positioned in a corner formation.
  • In-line: Cubicles arranged in a straight line.
  • In-line with Return: Cubicles in a straight line with an additional cubicle at the end, forming an L-shape.

Made-to-Measure Cubicle Solutions

While standard dimensions serve as guidelines, it’s important to recognise that not all washrooms conform to these measurements. Existing buildings, heritage sites, or unique architectural designs may require tailored solutions.

Fortunately, we at North East Toilet Cubicles offer made-to-measure cubicle options, allowing for customised dimensions to fit precise site requirements. This flexibility ensures that even the most challenging spaces can accommodate accessible and compliant toilet cubicles.


Cubicle Materials and Finishes

In addition to dimensions, the materials and finishes used in toilet cubicle construction play a crucial role in durability, hygiene, and overall aesthetics. Common materials include:

  • Melamine-Faced Chipboard (MFC): A cost-effective option suitable for general washroom environments.
  • High-Pressure Laminate (HPL): Offering increased moisture resistance and durability.
  • Compact Grade Laminate (CGL): A waterproof and highly durable material, ideal for wet environments like showers and changing rooms.


Maintenance and Cleaning Considerations

Toilet cubicles are subjected to high levels of foot traffic and moisture, making maintenance and cleaning crucial aspects to consider during the design phase. 

Factors to keep in mind include:

  • Material Durability: Selecting materials that can withstand frequent cleaning and exposure to moisture.
  • Ease of Access: Ensuring cubicle configurations allow for efficient cleaning and maintenance.
  • Ventilation: Incorporating adequate ventilation systems to control odours and moisture levels.
  • Cleaning Protocols: Establishing clear guidelines for cleaning and disinfection procedures.



Designing toilet cubicles that adhere to building regulations while meeting user needs is a multifaceted endeavour. By understanding the nuances of cubicle dimensions, configurations, materials, and accessories, you can create inclusive and functional washroom spaces that promote dignity and accessibility for all.

Remember, compliance with regulations is not just a legal obligation but a commitment to fostering an inclusive society. By embracing the principles of universal design and staying informed about evolving standards, you can future-proof your toilet cubicle design and contribute to creating a more accessible built environment.
