How Big do Toilet Cubicles Need to be?

Using the toilet in a public place should be as comfortable and accessible as possible. This can be achieved in several ways – through thoughtful washroom design, proper cubicle layout and ensuring there’s enough space for users to move around safely. One of the most important aspects of comfort and accessibility is the size of the toilet cubicles themselves.

Cubicles that are too small are not only uncomfortable but can be completely unusable for those with disabilities or reduced mobility. So, how big do toilet cubicles really need to be?

Standard Toilet Cubicle Dimensions

When planning commercial toilet cubicles, it’s important to meet the minimum requirements laid out in building regulations such as Approved Document M and Part T. A standard toilet cubicle must be at least 800mm wide and 1500mm deep.

Additionally, there must be a minimum 450mm of manoeuvre space within the cubicle to ensure it’s accessible in case of emergencies. The door should be at least 600mm wide, but ideally wider and can be designed as an outward opening door to enhance usability. 

Enlarged Cubicles

In any public building or commercial environment with four or more cubicles, at least one should be an enlarged cubicle. These offer improved accessibility for ambulant users and those with reduced mobility.

An enlarged cubicle should be a minimum of 1210mm wide, maintaining the 1500mm depth. This extra space allows for the installation of essential accessibility features like grab rails, IPS panels or even vanity units. Some enlarged cubicles may also incorporate baby changing facilities for added functionality.

Ambulant Toilet Cubicles

Ambulant toilet cubicles are designed for individuals who can walk but may require additional support. These cubicles often feature cubicle fittings like horizontal and vertical grab rails, as well as anti-finger trap hinges for added safety.

To meet regulations, the minimum size should be 800mm wide, with sufficient room for a closed fist to comfortably use any handles or locks. The door should always be an outward opening door, offering greater room for movement inside.

Disabled Cubicle Sizes – Wheelchair Accessible 

Wheelchair-accessible toilet cubicles are designed to meet more specific accessibility standards. Often referred to as disabled cubicles, they must include adequate cubicle dimensions and thoughtful layout to be compliant.

The door must open outward with a minimum clear width of 900mm, and the internal space should measure at least 2220mm by 1500mm. This allows for full wheelchair rotation and clear access to a WC and washbasin. Grab rails should be positioned strategically for safety, and the door handle and lock should be operable with minimal strength or dexterity.

For environments such as schools, nurseries or swimming pools, making these cubicles fully accessible is especially important. With a full range of washroom products and cubicle fittings available on the market, it’s easier than ever to build made-to-measure, cost-effective solutions that meet all user needs.

Why Does Cubicle Sizing Matter

Ultimately, the cubicle size you choose depends on your available space, user needs and the type of public buildings or environments your facilities will serve. While there are minimum size requirements laid out in approved documents, going above and beyond these recommendations will create more comfortable, inclusive and practical spaces for all users.
