In the outdoor pools, you must wear appropriate swim attire. The bathing area inside the single gender area (8 various temperature large tubs) does not permit clothing. You will be issued a t-shirt and shorts "spa uniform" for the saunas and other areas.
Bathing suits are only for the outdoor pools and must be appropriate. The bathing chambers require you to be nude and if you're caught wearing bathing suits in the indoor bathing pools you'll be kicked out.
