Toilet placement for accessibility…?


This illustration has at least three violations, if built today in California

Why is it so confusing? well, in a nutshell, here is why…

  • 1991 ADA min 16″ max 18″ from wall to center of toilet.
  • 2007 CBC 11B 18″ to center of toilet +/- construction tolerance depending on jurisdiction.
  • 2007 CBC 11B ambulatory stall min 17″ max 19″ from wall to center of toilet.
  • 2010 ADA min 16″ max 18″ from wall to center of toilet. (no change from 1991)
  • 2010 CBC 11B 18″ to center of toilet +/- construction tolerance depending on jurisdiction.
  • 2012 CBC emergency amendment to 11B min 16″ max 18″ to center of toilet.
  • 2013 CBC 11B min 17″ max 18″ from wall to center of toilet.

In my opinion, designers should design projects with public accessible restrooms so accessible stall has a finish toilet centerline of 17.5″ from closest wall and also indicate flush lever to be on wide (open) side of toilet transfer area.

Note: Ambulatory stall only required in multi use restrooms, and only if a fully accessible stall is also installed. The min 17″ max 19″ may not be used in single use restrooms.

*Residential CBC 11A should be verified by a CASp for compliance; 2013 CBC 11A minimum 18″ from vanity cabinet or bathtub to center of toilet.
