Onsen SF

Onsen SF brings the principles of Japanese onsen bathing culture to the Mission District of San Francisco in a sleek urban setting. The facility offers private soaking rooms with mineral-enhanced baths heated to around 40°C, alongside cold plunge pools, eucalyptus steam rooms, and a sauna. The design philosophy draws from traditional Japanese bathhouse aesthetics while addressing the needs of a contemporary urban clientele seeking restorative water experiences without leaving the city.
