Unisex changing rooms, bathrooms, toilets, spa, sauna etc?

In Europe you'll notice that a lot of bathrooms, changing rooms, showers, sauna, toilets are Unisex and communal. Often with attendants. Nudity is Tcommon and run of the mill. There are usually attendants and people are well behaved and relaxed. This is more mainland Europe & not really in the UK.

Do you get this outside of Europe?

Heard that some colleges/uni in USA are unisex ( or co-ed as they say) communal bathrooms. Not sure if that is true as thought USA was not relaxed/liberal like that.

Life style/nude beaches? lol
