Where a Changing Places Toilet is being installed in an existing building, it should be conveniently located within easy access of the entrance of the building, or alternatively adjacent to other sanitary facilities in the building. The route leading to the Changing Places Toilet should be easy for everyone to use. This may require alterations to existing corridors and doors along the route leading to the Changing Places Toilet. For example, doors along the route to a Changing Places Toilet may need to be widened and/or held open. 

TGD M 2022 includes specific provisions relating to the installation of a Changing Places Toilet in an existing building.
