The following clearances are designated according to ADA Accessibility guidelines. The ADA guidelines should be taken into consideration when designing a public restroom that is universally accessible. Each guideline is enforced in order to secure a safe and functional environment for those using some sort of physical aid, such as a wheelchair. The clearance below the sink and between the edge of the sink and the wall allows a person to pull his/her wheelchair safely underneath while still allowing them to be close enough to use the controls.
- knee clearance(from the edge of the sink): 8in minimum
- toe clearance: 6in maximum
- total space from the edge of the sink to the wall: 17in minimum
- bottom of the sink bowl: 27in minimum from floor
- bottom edge of counter: 29in minimum from floor
- top edge of counter: 34in max from floor
- piping: 9in minimum from floor (“Lavatories and Mirrors” 53)
