i have now heard of multiple plumbers failing ada compliance shower valve location by being to far in from curb. does any one know what they are now.
i know it used to be in a 36" x 36" was opposite of seat 38"-48" high and 18" max deep. the only other thing is that the showers were deeper than 36"
