I'm from the UK. It seems to be a bit more complicated here; increasingly, environments consisting of perfect strangers --- such as public pools --- are getting individual changing cubicles. (Possibly, I suspect, because you can make them unisex[1] and not have to have outfit two complete changing rooms.) [1] People keep using that word. I don't think it means what we think it means. But environments where people know each other, even by association, still have the locker room thing. e.g. gyms, sports centres, etc. Also, bear in mind that this is all hugely culture-specific. When I went to Korea and visited my hotel sauna, discovering that there were two, one for men and one for women, and the one I saw was populated almost entirely by elderly Korean completely naked businessmen, was a bit of a culture shock. It didn't take long to get used to but I wouldn't say it was ever pleasant. Man, humans are ugly without sexual attractiveness tilting the scales...
