What are the dimensions of a disabled changing room?

Within commercial washroom facilities, the building's owner or managers have a responsibility to provide adequate accessible changing room facilities for disabled staff and visitors.  

If you need clear and concise Disabled Changing Place Refurbishment advice, please contact our Washroom Design Team.

Document-M of the building regulations (Volume 2) sets out the specification that these should be provided to.  

The recommended dimensions of a disabled changing room are at least 2200mm deep x 2000mm wide.

Disabled changing room dimensions


In addition to dimension, design considerations of a disabled changing room include :

  • Doors should preferably be outward opening and are fitted with a horizontal closing grab rail fixed to the inside face.
  • A wall-mounted tip-up seat should be supplied.
  • An emergency assistance alarm system should be reachable from the wall-mounted tip-up seat 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.
  • A compliant Doc-M changing room pack.

Commercial Washrooms can assist with all aspects of your disabled changing room installation, including adapted toilets, shower and changing tables, and other products to help with accessibility, including disabled shower seats, and adjustable wash basin packs

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.
