making someone cross a door handle boundary without a plausible opportunity to wash their poopy hands is a deal breaker to me, even if only 1/3 of people are actually bothering to really soap up
Not sure about other countries, but it's extremely common in France for the toilet to be in its own room, and then the washbasin and shower in another. Not just in multi-residential either.
Dunno the history (gives a bit more flexibility: a showerer doesn't constrain the toilet), but could also be an aversion to not clean yourself in the same place you poop.
