This article provides minimum facilities required in public buildings as sanitary facilities.
General Instructions
(1) There should be separate facilities for men and women.
(2) Washbasins should be provided in equal numbers to WCs with one for every five urinals.
(3) In most public buildings, a minimum of 2 WCs should be provided so that one may act as a reserve if the other is not functional.
(4) Where there is only space for one toilet in a building, it should be a wheelchair-accessible unisex toilet, wide enough to accommodate a standing-height wash basin. Otherwise, at least one wheelchair-accessible WC should be provided at each location in a building where sanitary facilities are provided.
