Entry No. 37 — the San Francisco file — filed under: sauna

Alchemy Springs & Sauna Garden

A half-built social bathhouse that opened its 2,500-square-foot sauna garden to the public while the rest of the site is still under construction around it — SFGATE clocked its freestanding sauna as the largest in the country. Strangers share benches under string lights and outdoor heaters mid-construction, then dunk in the cold plunge next to exposed scaffolding.

The move: Grab a same-day sauna garden slot, cycle heat and cold plunge shoulder to shoulder with strangers, and talk about how weird it is that you're doing wellness rituals inside a construction site in the middle of Nob Hill.
