I think a bathhouse would be fun, but you have to consider historically how bath houses have been utilized. Besides the earliest concepts in ancient Greece, the need to bathe, (separate quarters for men, women and slaves and for those with more coinage, all sorts of spa luxuries,) the Romans took it to a whole new level of decadence with sports facilities, food and entertainment, and some of these decadence's are not so pg friendly. Also the bathhouse venue in modern times, was/is definitely not pg friendly, there is a sleazy element conjured in the very word bathhouse because of this modern venue. We have taken the early historical concept and it now flourishes as the "Spa." Just some thoughts.
