The most impressive bathroom layout I’ve ever seen was pretty open concept. It seems strange, but let me explain.
Directly off of a major area was basically a hallway, on that hallway was a set of doors. Full sized doors. One right after the other. Each door led to a room which is smaller than most closets, containing a toilet. That was about it for what’s in the room. Of course the usual toilet/stall amenities were available. At the end of this hallway of toilet closets, was a long sink for handwashing.
It was entirely gender neutral, and there was zero risk of rape or any other perceived danger.
I’m sure the closet stall design took up slightly more floor space than your average bathroom stall. Honestly it seems like a small price to pay to have a room all to yourself when you’re doing your business.
I’m sure that adopting this design would get cries from the fragile men about their precious urinals. Honestly, fuck them. The toilet does the job, you animal.
