Does texture tile behind grab bar meet ADA?

[Yikes]

See the tile texture in the image below - note the shadow lines indicate some kind of 3D texture.



How much tolerance is allowed on the 1.5" space for grab bar distance from the wall (under CBC 11B-609.3) before the tile texture is considered to be a "projecting object"?

How much tolerance is allowed

It's ADA where -0- is a tolerance.

This tile doesn't work well with escutcheons.



I'd have to look and Chapter 11 is just too much to sift through. I do see a concern. As one rolls the hand into the strength position the knuckles could ride against the top of the outcrop and become grievously injured.

If it were a handrail the surface behind it has to be 100% smooth. That's the ticket ... go with smooooth.

I do not see, based on photo, sharp or abrasive elements.
I Do not See, based on photo, any violation of the 1.5" space between the wall and the grab bar

• 11B-609 Grab bars
• 11B-609.5 Surface hazards. Grab bars and any wall or other surfaces adjacent to grab bars shall be free of sharp or abrasive elements and shall have rounded edges.
• 11B-609.3 Spacing. The space between the wall and the grab bar shall be 1½ inches

"...grievously injured...??
i see it as smooth....?

Regardless of smoothness vs roughness, my concern is that ADA/11B-609.3 has an absolute dimension of 1.5" space between bar and wall - - not more, not less. Of course, any absolute number in the codes implies some construction tolerance. But construction tolerance is not the same as "design" tolerance, and the shadow lines in the tile indicate they were designed to specifically vary depth in order to create the shadow.

No that tile will not be appropriate behind the grab bars. There is a reason why we can no longer run "flush recessed" toilet accessories behind grab bars. The slight difference between the tile only and the recessed accessory depth is not compliant. Neither would this tile be.

I was going to say that if the bar was mounted on one of the high spots of the wall, the gap would not be less than 1-1/2”.

https://www.access-board.gov/files/ada/guides/using-ADAstandards.pdf says in Conventions (104):

"A tolerance is an unintended, but permitted (i.e., “tolerated”), variation from a specified dimension resulting from the process of construction or manufacture. The ADA Standards recognize conventional industry tolerances for dimensions not expressed as a range."

+ or - 1/16" should be reasonable, and would be as close as you could get just using a measuring tape.
