I assume....One main door and a toilet and sink....just like home. What's the problem.
“What’s the problem?”
The problem is a violation of private property. The state has no business telling property owners how to use their restrooms. George III was quite the libertarian compared to today’s pols.
May sound reasonable to some - I agree… But remember baby steps...
It takes a lot more total space, and costs a lot more to install several one-person facilities, than it does to have several “appliances” in a single larger room. A lot more. How’s that for a problem?
I should have added another problem — with multi-stall (or urinal) washrooms, some users can wash up, powder their noses, etc. while others are still “going”. You get a lot more thru-put/sq. ft. that way, compared to single use rooms.
“Single stall”, meaning one person in at time with the outer door locked? I don’t have much of a problem with that, last time I was at a department store they had a bathroom like that, me and a lady were waiting for it at the same time, that was kinda awkward though....
