Sauna Hut(2 Locations)

Sauna Hut is a therapeutic wellness studio rather than a traditional spa, tucked on Oswego Pl NE just steps from Green Lake in Seattle. This is one of two Sauna Hut locations, and the Green Lake studio focuses on three core services: private infrared sauna, clinical massage therapy, and red light therapy on a medical-grade bed.

Sessions run from about 20 to 90 minutes depending on the service. Infrared sauna time in a private suite (solo or for two) starts at $25 for 30 to 60 minutes. Therapeutic massage — the signature offering, including deep tissue, sports recovery, and specialized work like Intra Oral Therapy and Manual Lymphatic Drainage — starts at $65 for 30 to 90 minutes. Red light therapy sessions run up to 20 minutes starting at $35. Couples can book sauna sessions together.

Access is adults-only, with a minimum age of 18, and this is not a walk-in spot — reservations are required and slots for private saunas are limited. The studio is open daily from 8 a.m. to 9 p.m. Because the therapies are framed as dual-purpose (both general wellness and, when tied to a diagnosed condition, therapeutic), services here are HSA and FSA eligible under many plans, which is worth confirming with the studio at checkout.

Given the Green Lake location, a common pattern is pairing a walk or run around the lake with a sauna or massage session afterward, though that's a matter of routine rather than anything the studio requires.
