Fjord offers a floating sauna and cold-plunge experience on the San Francisco Bay in Sausalito. Guests use heated saunas, typically maintained around 190F, and may plunge in the bay within a marked zone using platform ladders for exit. The business offers shared sessions, with access to both saunas and capacity of up to eight people total, and states that saunas are cleaned between each party and at the end of each day.
