Ambulatory Stall Dimensions

[jmoreno]

Scenario- An ambulatory toilet stall is 37" wide and 60" long. The toilet-center-to-partition wall dimension is 17" to the right, 20" to the left. Given the Accessibility Code language, is this code compliant?

An ambulatory toilet stall is 37" wide and 60" long. The toilet-center-to-partition wall dimension is 17" to the right, 20" to the left. Given the Accessibility Code language, is this code compliant?

Per A117.1-2009 Figure 604.10 and A117.1-2021 Figure 604.10.1, the distance from the centerline of the toilet to the partition must be 17” to 19”.

You’ll want to confirm which version of A117.1 is in effect for your project because some things change between versions. For example, in the two figures referenced above, in A117.1-2009 the stall width is an absolute 36”, in A117.1-2021 the width is 35” to 37”.

This might be relatively easily fixed if you can pad out the side that is 20” from the toilet to bring that down to 19”.

And I am still trying to get them to fix the min. ambulatory stall depth to match wheelchair depth....Because they get pissed when they have to rip out all the stalls and start over at CO inspection....

Currently the requirement is 35" - 37". The concern would be if the 17" - 19" dimension is required on both or just one side of the water closet center line.

Both....they don't want you to reach too far for the grab bars rendering them less useful...

Why would the depth of an ambulatory stall have to match the depth for a wheelchair, ambulatory stalls are intended for people who can walk.

Both sides. The 35” to 37” width of the stall and the 17” to 19” centerline dimensions have to be coordinated.

For example, if you have 17” from the centerline of the toilet to both partitions that complies with the centerline requirement but fails because the width would be 34”. If you have a 35” wide stall you can’t use 19” for one of the centerline dimensions because the other side would be 16” (16” is only allowed for wheelchair accessible stalls.)

The ambulatory stall is the only one that is still 60”

I just go ahead and make them all 60" deep.

Both sides. The intent is for the WC to be centered in the stall. If it moves an inch one way or the other, the dimension from the centerline to each partition still has to fall within the range of 17" to 19".

That's what most designers do. The standard wheelchair stall dimensions are minimums, not absolute, so there's nothing to prevent making them 4 inches deeper than the minimum.

I appreciate all the input. For the record, I agree with you and this is how I've always enforced it. However, you would be surprised with the Access Board's approach. @Yankee Chronicler @steveray @walker.t
