Toilet Cubicle Regulations Explained

When it comes to designing or refurbishing washroom facilities in new or existing buildings, compliance with building regulations is essential. Whether you’re fitting out commercial toilet cubicles in an office, installing school toilets, or managing public leisure centres, making sure the layout meets UK requirements is key to creating an inclusive and accessible space.

Understanding Toilet Cubicle Regulations in the UK

UK toilet cubicle designs are regulated by building regulations to make sure they are safe, accessible and are also functional.

• Building Regulations Part M (Access to and use of buildings)
• BS 6465 (Sanitary Installations)
• Health and Safety at Work Act 1974
• Approved Document T (Internal layout and usability)

These documents offer detailed guidance on layout, door opening direction, minimum width and accessibility to accommodate all users, including ambulant disabled persons.

Standard Toilet Cubicle Dimensions and Requirements

The toilet cubicle dimensions required to meet most UK washroom design regulations differ with standard, enlarged and ambulant cubicles.

Standard toilet cubicle dimensions: Minimum width: 800mm, Toilet cubicle length: 1500mm, Overall toilet cubicle length (including doors and fittings): Up to 1800mm.

Enlarged cubicles (for users who require extra space, but are not full wheelchair users): Width: 1200mm, Must include grab rails, often including a vertical grab rail.

Ambulant Disabled Cubicle: Minimum size: 800mm x 1500mm, Requires grab rails on both sides and accessible door opening.

All cubicles should feature secure doors and allow users to operate locks using a closed fist, as outlined in Approved Document T.

Accessible Toilet Cubicles and Universal Toilets

A fully wheelchair-accessible cubicle or universal toilet must include the following:

• A minimum clear room size of 2200mm x 1500mm
• An outward opening door for ease of access
• Turning space for a wheelchair
• IPS panels to conceal plumbing while maintaining accessibility
• Clear layout including grab rails, an emergency pull cord and a raised height WC

If there’s only one cubicle available in a given area, it must be designed as an inclusive universal toilet to ensure compliance.

School Washroom and Cubicle Layout Compliance

Regulations for cubicles in schools require special consideration towards privacy, supervision and gender seperation. Pupils over the age of 8 must have access to separate toilet cubicles for boys and girls unless universal toilets are provided. Toilet cubicle dimensions should follow the same standards, but cubicle heights may be reduced in primary settings for visibility. High-durability materials are recommended to withstand heavy use and reduce vandalism in educational buildings.

Workplace and Public Toilet Cubicles

In offices and public buildings, the layout of cubicles and access routes must be sufficient in number for staff and visitors, clearly signed and well-lit, equipped with outward opening doors where accessibility is a concern. They must also be inclusive of ambulant disabled and wheelchair-accessible cubicles.

The guidance recommends a combination of standard dimensions, enlarged cubicles as well as fully accessible WCs for best practice.
