What are the dimensions of a disabled bathroom?

Document-M of the building regulations offers detailed advice on the size and layout of disabled bathrooms. Specifically, Volume 2 of the 2010 regulation covers buildings other than dwellings.
If you require clear and concise advice on Disabled Toilet Refurbishment, please get in touch with our Washroom Design Team.
The recommended dimensions of a disabled bathroom are at least 2700mm deep x 2500mm wide.
Fully compliant Doc M Packs can be viewed from the following links:


Design considerations for a disabled bathroom include :
- Doors should preferably be outward-opening and are fitted with a horizontal closing bar fixed to the inside face.
- The bath should be equipped with a transfer seat, 400mm deep, and of equal width to the bath.
- An emergency assistance alarm system should be reachable from the bath or the floor.
- Blue colour contrasting grab rails should be installed against white background walls for the visually impaired.
- The correct number, size, and positioning of grab rails should be installed within the room.
Commercial Washrooms can supply all of the correct products for your disabled bathroom installation.

Please note that since 2015, Approved Document (or Part) M of building regulations has been divided into two volumes. Volume 1 pertains to access to and use of buildings used as dwellings and is beyond the scope advised by Commercial Washrooms. Approved Document M: Volume 2 is concerned with buildings other than dwellings and is the guidance that commercial premises owners and managers should adhere to. It is in Volume 2 that more information can be found regarding the design and layout of accessible washrooms and bathrooms, including the dimensions of a disabled toilet room, accessible bathroom, changing room, or shower room.
