What are the dimensions of a disabled toilet room?

The question of what size the modern disabled toilet room within a commercial use building should be is a common one. The following article sets out to explore the required dimensions.

According to Document M of the UK building regulations access to and use of buildings other than dwellings, wheelchair users should be able to comfortably approach, transfer to and use the sanitary facilities provided within a building. This requires the provision of a wheelchair-accessible unisex toilet.

The recommended dimensions of a disabled toilet room are at least 2200mm Deep x 1500mm Wide.

Rooms larger than these dimensions will provide a larger turning circle for use by wheelchair users, which in turn will provide additional comfort and ease.

The minimum disabled toilet room dimensions are to exclude any items installed which are not required or mandated as part of a document M compliant disabled toilet room.

Therefore if there are any items projecting into the room such as heat emitters (radiators), or baby changing tables the measurement of the room for the purpose of establishing if the room meets the minimum dimensions should be taken from the narrowest point between any wall and one of these fixtures.

Other design considerations for a disabled toilet room include:

  • Doors should preferably be outward opening and are fitted with a horizontal closing bar fixed to the inside face.
  • An emergency assistance alarm system should be provided.
  • Mixer taps with an easy to grip lever should be installed to assist users with limited dexterity.
  • Blue colour contrasting grab rails should be installed against white background walls for the visually impaired. Alternative colour grab rails are permissible provided there is adequate tonal contrast between them and the surface they are mounted upon.
  • Suitably manufactured toilet pans and hand wash basins specially designed for use in a disabled toilet room should be installed.
  • The correct number, size, and positioning of grab rails should be installed within the room.
  • Toilet flush handles should be of a paddle type design to assist users with limited dexterity.
  • Compliant Doc-M toilet pack.

Please note 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 that are used as dwellings and is beyond the scope that Commercial Washrooms advises. Approved Document M: Volume 2 is concerned with buildings other than dwellings and is the guidance commercial premises owners and managers should adhere to.  It is in this volume 2 that more information can be found relating to the design and layout of disabled accessible washrooms and bathrooms, including the dimensions of a disabled toilet room, accessible bathroom, changing room or shower room.
