Switzerland's spa facilities tend to be pristinely clean, somewhat luxurious and not too cheap, although you usually come out feeling refreshed and relaxed! Nude areas, or Nacktzone, for both sexes are common (especially in saunas), which may be a new experience for you if you're not a local. It may also interest you to know that you usually enter saunas sans clothing, with the exception of a towel (which you actually take off and just sit on). Women-only areas are also common.
