American here! I don’t recall ever living in or visiting a place where the switch was OUTSIDE the bathroom. Granted, I’ve also mostly lived in places with extensive central air conditioning or a fairly dry/cold climate, so I wonder if humidity is a factor?
Huh.
That is genuinely interesting.. maybe humidity is a factor bc a lot of... "traditional" or older house bathrooms tend to be wet bathrooms so I assume the humidity would be even worse... or to not accidentally zap urself w the switch?
