For the sake of
posteriority this is a question that must be addressed! :moon:
Safe? Safe from what? Other people? I have rested my (T)rump in 3rd world **** holes and 5 star hotels and I can truthfully say that I have never felt threatened in a bathroom by anyone. It matters not to me who might also be using the same bathroom.
Having had dysentery twice I feel somewhat knowledgeable about extended bathroom visits in foreign lands. All things being equal I prefer my own facilities. Nothing like familiarity can make an extended visit more comfortable.
Butt, no, I have never felt threatened by other people in a bathroom.
There was an incident once where using a trough in Amsterdam that I had to abruptly change my aim as a cleaning woman insisted on cleaning the trough while a few of us were using it. Seems she wasn't concerned about being caught in a crossfire.
If you mean safe from disease I'd have no reason to believe the OP bathroom would or wouldn't be reasonably clean. I would say that I have never copped a squat in an airplane bathroom and sincerely hope I never have to.
