On alternating days, men and women sauna and swim naked in Urjönkadun Uimahalli, a 1920s art deco public bath house in the heart of the Finnish capital. This is the best experience ever, The Finns invented the sauna and feel quite comfortable, unlike many of their Ango-American brethren, being naked.
While sauna might a mixed gender affair in people’s homes, it is not at the bath house. There are separate days for women and men, but once you get inside there is little privacy from your fellow bathers. Bathing suits are not banned, but almost everyone goes without one. Those who desire a private sauna or a massage can reserve one ahead of time.
