Sure, in practical terms it’s probably overkill, but that’s why I say it’s the “perfect” hygienic restroom. You don’t need to touch anything at all with your hands in the entire room after you leave the stall/urinal.

Hell, that’s another item, come to think of it – floor-flushing toilets/urinals. The electric eye/sensing ones are fine too, I guess, but having a button on the floor I could just step on (which I have seen in places) is my preference. Minimizing hand contact areas in a bathroom is always a good thing.
