I hope you aren't thinking I am dissing ADA requirements. I have no complaint with the idea.While I agree most ADA requirements are a PITA, after spending 6-months in a wheelchair after a bad ladder accident I better understand them.
You are correct that is makes it no harder to install.I can see rifles point but it makes no difference to me. The ADA requirement on a urninal dosent make it harder to rough in or install so it dosent bug me. If it makes any ones life easier I got no problem with it.
