Often when there is a new ruling or clarification about single-sex spaces in the UK, I read comments (not here) like “Unisex changing rooms are normal in Europe, it’s just Brits being prudish”.
I lived in Central Europe for a long, long time - Germany mainly - and to be honest I never came across unisex changing rooms or toilets.
What are your experiences? Have you been to many (or any?) places in Europe where unisex changing rooms and toilets are the norm?
Germany does have a very progressive law on self-ID* (including for prisoners) but in daily life, changing rooms and toilets in my experience were always sex-segregated. I did once witness an argument in the ladies’ communal showers after swimming as a woman had brought all her children into the showers with her and one of them was a boy of about 12. (It’s considered hygienic to shower naked after swimming so the women were especially sensitive to overage males).
Sometimes there were slightly ridiculous situations - “textile free” evenings at the local swimming pool where those partaking changed separately and then met naked on the poolside, or stripping off separately and then getting into the same sauna… And of course the lakes often had a naked bank, where everyone stripped off together. But places were designed with separate changing rooms, and there were often allocated “ladies’ days”, “men’s days” and “mixed days” at saunas or naked sections of thermal baths. So people could choose to be naked in front of the other sex or not.
*I guess that means that nowadays men can go into women’s places if they identify as such, and vice versa. But only if they say the magic words.
