You'll know you've fully been indoctrinated into Germany once you can say you've been to a nude…read moresauna--and actually say you like it. It's winter, it's freezing, you can't feel your toes. Go to the sauna! This one was close to my flat--it's a bit bizarre to get to the sauna part. I wondered around what looked to be a hospital for awhile. I finally found an elevator, stumbled down a low-lit hallway, and found an unmanned desk. I eventually found the guy, bought a day pass (I can't remember how many Euro, but it wasn't outrageously expensive) and checked in. Once inside, there is, eh hem, lots of nudity, giant showers, steam rooms and saunas. They also have lounge chairs where you can hang out after, read a book or listen to some music.
