A follow-on to this requirement (which I had to head off abo ut 7 years ago – good luck, Betsy!) is the requirement to capture all of t hat shower wash water and “dispose” of it as hazardous waste.  So rather than the dish idea, the floor drain and trench drains at the room threshold had to drain to a holding tank in the basement as someone’s bright idea for “pollution prevention.”  We had to build o ne building with a tank in the basement and then cooler heads prevailed, point ing out that the floor is required to be secondary containment.

Hope this helps – the dish idea wasn’t going to fly with our ADA compliance folks so I had an ally there.

Good luck!

Oh, like that's going to work!  The volume of water comming off that showe r will turn that shower area into a I inch-deep pond surrounded on 4 sides wi th mini falls.  I'd love to find out who thought up that one.  Monon a

I am currently involved in construction of two new laboratories and was instructed by the city commercial building review department to include a 1" high curb around the shower area to keep hazmat from entering the f loor drain in the event of a spill.  Also, the curb has to be sloped on bot h sides to allow accessibility.
