Toilets can unite different areas of a building during the design process. Stand-out features, such as individual hand basins in cubicles bring the wow factor to toilets while creating a comfortable environment for users.

4. Dimensions of Urinals

For men, urinals are more space efficient, faster, and more sanitary in busy public restrooms than toilet stalls. The accessible urinal is required to have a 760 mm x 1220 mm clear floor or ground space positioned for a forward approach.

2. Commercial/ Public toilets -
