Run by Sally Dunton, the bathhouse is just as dubious as you might imagine: there are beds in each room, rather than baths. There is no real benefit from paying for the "baths" as one can lockpick into the rooms and simply talk to the girls, one of whom, Jenny, gives some trivial details about Vic.
Notes
Spending paid time with girls does grant a "Gigolo" notation in the karma column for what it is worth.
One of the girls has a Cat's Paw magazine on her, which can be stolen.
Although it was cut from the game, a re-addedVirgin of the Wastes reputation will be lost after you have sex with one of the girls.
