As you approach the Friedrihsbad through a public garden, you see a highly decorated granite building. Climbing a small flight of steps, you walk through the door into the lobby where you pay your fee. This entitles you to three hours in the facility. Typically, this is plenty, you can only have so much fun! But if you overstay your welcome, you'll be charged for each extra half-hour upon your exit. At this point, you'll also have to decide if you want the optional sponge and brush massage, which costs a bit extra.
Climb the staircases. Men go to the left, women to the right. Everything's the same on both sides. From this point, simply follow the signs which are provided in German and English; you needn't worry that you'll get lost.
