From publisher blurb:
In the days of old, the public bathhouse was as much of a social center as any tavern. So why not mix things up and start your adventure somewhere a little more clean? Sure, the half-orc may object to soapy water (after all, he'd get a -2 penalty on Diplomacy checks against his own people for being dishonorably cleansed of his enemy's blood), but I'm sure the elf noble wouldn't object to spending time in a more refined and relaxing establishment.
Within Hygiene, we cover both the effects of neglecting cleanliness and places where you can scrub after delving in a mucky dungeon! Included are maps for each of the 6 locations inside, including 3 bathhouses (Japanese, Roman, meditative), a barber shop, laundry pools, and a salon.
