How Boston does the sauna
Boston's sauna history runs through its steam baths. Dillon's Russian Steam Bath in Chelsea dates to 1885 and keeps the old rhythm: a granite-rock hot room, cold water and separate days for men and women. The same family now runs the former Finland Steam Baths in Quincy as Dillon's Health Spa, with private sauna rooms. In Newton Highlands, Kelo Spa & Steam is built around a sauna made of kelo logs from Finnish Lapland.
The newer places are social saunas in the Nordic style. Moki Sauna has a year-round location in South Boston and an outdoor sauna village in Allston, with shared sessions, cold plunges and a co-ed crowd in swimsuits.
Contrast therapy studios in the Seaport, South Boston and Chestnut Hill rent private suites that pair an infrared sauna with a cold plunge.
