Additional sanitary facilities beyond those required to comply with this guidance need not have strengthened walls.

Examples of compliant WC layouts are shown in Diagram 2.6. d. The door opens outwards. Diagram 2.5 Sanitary fittings, associated clear access zones and permitted encroachment of basins. Diagram 2.6 Examples of WC-cloakroom layouts. 2.28 Where the dwelling provides both an accessible bathroom with a WC and a WC/cloakroom within the same storey, the WC/cloakroom may comply with the provisions of Diagram 1.3. Bathrooms 2.29 To provide convenient access to a suitable bathroom, the dwelling should comply with all of the following. a.
