Because piss being splashed back onto a bloke’s slacks and then walked around his workplace indefinitely is better than mopping up piss from a toilet floor? 🤡
While that paint is interesting a targeted attempt to deter drunks from pissing up the walls of our high streets doesn’t seem at all suitable for the enclosed space of toilet cubicle - the splash back will get transferred to things the next occupant will touch, either on purpose, eg tap handles and the button on an air dryer or by brushing a leg against a toilet pan or an arm or bag against the wall
Some men do habitually sit down to piss, I hear it’s very common in Holland and Germany, but it’s seems utterly silly to expect all males to change their habits for the sake of mixed sex loos that most people, male and female, don’t want.
Plus urinals reduce physical footprint of the toilet area in a public building, lesson queuing time and are far more environmentally friendly than flush loos.
We can’t walk back on environmental progress for the sake of a tiny percentage of people who won’t accept that their sex is relevant to life, to law, to society.
Personally, I would much rather not be subjected to male piss smell, it’s just stronger and harder to eradicate than female piss smell, something that can be observed across the mammal kingdom. A public toilet can be perfectly clean and tidy yet the gents bogs will always smell worse than the ladies.
This isn’t something that chaps can do anything about and even if men’s loos are less messy (which I seriously doubt, although I’m sure the gents bins need less frequent emptying and are thus less likely to overflow) they still smell more.
Foisting mixed sex facilities on everyone is pointless because it will cost loads and make everyone less happy.
Just add a few extra single user spaces (big enough for parent and child together) and leave everyone else out of it.
