Bathrooms are one of the most important rooms to make sure they follow the guidelines. A typical bathroom is not built with any consideration for disabled persons, so it is important that you follow the ADA standards to make for the easiest access. 

These standards include:

  • The center line of a toilet shall be 16-18 inches from side wall or partition.
  • Clear floor space in a bathroom needs to be 56X60 inches or greater.
  • Sink must have a 30 inch by 48 inch clear floor area.
  • Sinks must also offer at least 17 inches of knee space.
  • The toilet must have 48x56 inches of clear floor space.
  • It is recommended that this floor space be 48x66 inches.
  • Residential dwellings may have the sink within this floor space, but commercial buildings must have additional space for the sink.
  • Grab bar needs to be a minimum of 42 inches long and 12 inches off the wall.
  • Behind the toilet, you need to place a 36 inch long grab bar. This bar must also protrude beyond the side of the toilet at least 12 inches.
  • The top of any grab bar must be 33-36 inches off the ground.
  • Toilet paper dispensers must be 48 inches above the floor.
  • Any bathroom must additionally have a 5 foot turn radius. 


Naturally, also make sure that all other ADA standards are observed in a bathroom, such as the doorway being 32 inches or greater and the ease of access for all switches and fixtures. Additionally, keep in mind that showers have their own requirements. This includes grab bars, but a shower seat remains optional.

Finally, it is important that all grab bars be installed in a reinforced area of the wall to afford the proper level of support. This reinforced area must extend further than the grab bar; for example, if the grab bar is 24 inches, the reinforced installation area must be 28-32 inches. The guidelines also include details on floor mounted or wall mounted fold-up grab bars.
