what are the disabled toilet requirements?

Document M of the UK building regulations lists the regulatory requirements for disabled toilet sizes. While we’ve summarised the most important elements a full read of the document is advised.

Document M states that wheelchair users should be able to comfortably approach, transfer to and use the washroom facilities provided within a building.

In order to meet building regulations, a disabled toilet requires:

  • A raised height WC with extra projection for wheelchair transfers
  • A washbasin with lever style taps to assist users with limited dexterity
  • Paddle style toilet flush mechanism for ease of use
  • Five supporting grab rails of a contrasting colour to aid the visually impaired
  • An outward opening Access door
  • An emergency assistance alarm system

Disabled washroom dimensions

Disabled toilets must be housed in a room that is at least 2200mm in length and 1500mm in width. Larger dimensions are acceptible though key fittings and amenities must still be located correctly.

Additional items not required by Document M may still be installed though Consideration should be taken to items projecting within the required space.
