How the Bay Area does the sauna
San Francisco's bathhouses mix several traditions. Japantown has Japanese-style communal baths and a Korean day spa within a few blocks of each other. Archimedes Banya in Bayview is a four-story Russian bathhouse with stove-heated rooms and a Turkish hammam. Newer places like Alchemy Springs and Onsen SF follow the social bathhouse model, with large shared saunas and cold plunges.
The bay itself is part of the experience at a few places. Fjord in Sausalito has wood-fired saunas on a floating dock, and you cool off in the bay. In Dogpatch, a barrel sauna sits on the waterfront at Crane Cove Park.
Across the bay, Berkeley and Oakland have smaller studios with infrared saunas, cold plunges and private sauna rooms you rent by the hour.
Before you go
- Bay water is cold all year. If a place uses the bay as its cold plunge, expect it to be colder than you think.
- Many places sell timed sessions, so book ahead, especially on weekends.
