Minimum bathtub size?

[ADAguy]

Nice photo but at a minimum a lift would be necessary to make it accessible.
The "loophole" acknowledges manufacturers dimensions established long before buildings codes.
Consider 4 x 8 plywood because of 2x4's at 16" o.c., 2x4' could just as easily have been 2x6's and 9 or 10' vs 8'.
$ driven decisions.

 

[Mr. Inspector]

I only saw them on TV but if the "walk in bathtubs" seat have the right height would it comply?
I know the door on them wouldn't pass code but they could glue the door shut to pass inspection.

Other than, walk in tubs are designed for SFD, NOT covered by the ADA.
Why wouldn't the door comply? Landings? The door is not part of the accessible POT.

 

[Mr. Inspector]

I was not thinking about a SFD, but where an accessible bathtub is required why wouldn't the interior of the bathtub need to be on an accessible route?

2009 IBC 1104.2 Within a site. At least one accessible route shall connect accessible buildings, accessible facilities, accessible elements and accessible spaces that are on the same site.

So just for the sake of an argument where is the exception for the interior of a bathtub since there is nothing in the code about the maximum height of the sides of the bathtub?

The only dimensional requirements are the ones set by ADA, ANSI117.1 and Fair Housing, which do not specify a height for bathtub apron edge, but require a seat between 17 to 19 inches.
