6.11 Sanitary Facilities
6.11.1 Sanitary facilities
Sanitary facilities include toilets, shower and bathrooms, baby care and ancillary facilities. Such facilities should be provided for the general public, persons with a disability, as well as the elderly and people with baby or young children.

The Design Manual Barrier Free Access provides the statutory requirements for toilets and WC cubicles, as well as bathroom and shower compartment.

Best practices are recommended for the widest spectrum of users. For instance, the provision of one unisex accessible toilet facility for each suite of male/female toilets on each floor is very useful as it facilitates the carer of the opposite sex to access the sanitary facility together with those who needed assistance. For large complexes, provide one separate unisex toilet with a maximum travel distance of 40m if feasible. Similarly, a separate unisex accessible baby caring area should be provided if feasible.

6.11.2 Toilets
The size of a toilet room (6.11.2a) should best be 2000mm x 2000mm. This will provide options for positioning the toilet pan. A clear unobstructed approach should be provided to the toilet, wash hand basin and hand dryer.

The toilet door should open outwards to provide a clear opening of at least 900mm and should include a horizontal handle. For privacy and safety, avoid the toilet door opening directly onto a public and/or circulation area.

Flushing control:
Sensor controlled flushing systems are preferred. Other options such as a lever flushing handle on the transfer side of the toilet is acceptable.

Wash hand basin:
A small wash-hand basin should be installed at a height not more than 750mm and it should allow for a knee clearance height of 550mm under the basin.
A tap with a lever handle should be provided, with the tap fixed on the side of the basin nearest to the toilet pan. A mirror above the basin is recommended, with its bottom edge at a maximum height of 1020mm from the floor and a minimum top height of 1880mm. It should be slightly tilted towards the floor for use by wheelchair users.
