Urban bathhouses are the contemporary city take on the sauna — Finnish or steam heat paired with pools, spa services, hot tubs, and cold plunges, run on bookable slots inside the city itself. Bathhouse-brand sites in New York, World Spa in Brooklyn, Knot Springs in Portland, Banya 5 in Seattle, Archimedes in San Francisco. Plan for a longer visit than a barrel session — the rooms reward it.
In San Francisco, 2 of the curated saunas fit this cut. See the full San Francisco guide for every venue in the city, or keep scrolling for just the urban bathhouses.
