Cold plunge temperatures in San Francisco: FAQ
- How cold is the cold plunge water in San Francisco?
- Of the 13 studios with a cold plunge we track in San Francisco, CA, 2 publish an operating temperature, and those run from 50°F to 55°F. The coldest published figure is at Immersion Spa. The other 11 do not publish a temperature, and we do not estimate one for them.
- Why do so many San Francisco studios not list a water temperature?
- Most studios in this market publish a booking page and a price and nothing about their equipment. We only record a temperature when the studio states it on its own website or booking page, and we link to that page so you can check it. Where you see no figure, the studio has not published one — that is worth asking about when you call, because a plunge without a chiller warms up through the day.
- Where do these temperatures come from?
- Each one is taken from the studio's own website, booking page, or published FAQ. Every figure on this page links to the exact page it came from and shows the date we read it. We do not take temperatures from review sites, aggregators, or search summaries, and we never carry a figure over from another location of the same brand.
