High-end health spas in hotels are normally frequented by out-of-towners, which is not to say they don’t make for an exquisite treat. Most Berliners head to local saunas and hammams for less expensive treatments. Finnish and Turkish in origin, respectively, both are especially popular in countering the winter blues. These treatments are popular enough that there is likely to be a sauna in your neighbourhood. As with lakeside culture in the summer, do not be surprised if Berliners attend saunas entirely naked, even in groups or with their families. You may wear bikinis or bikini bottoms in a spa, but the locals might wonder if something is wrong. If gender-mixed bathing makes women uncomfortable, they might prefer the all-women hammam in Kreuzberg listed below.
