The below shows a layout for a Hygiene Room for someone with disabilities which follows a Part M (Building Regulations) recommendation. In this example for a right handed transferee. In the education system toilet provisions should include a specialist hygiene room with fixed or mobile hoist and space for assistants to change a pupil.
In a primary school this should contain a changing bed and accessible WC unless this is included in an adjacent accessible toilet (9m2). In a secondary school, this should contain an accessible shower, sluice toilet and changing trolley.
