Wood-fired Sauna Service & Mobile Rental
Serving the North Olympic Peninsula & beyond
SeaTsu welcomes you to enjoy a curated wood-fired sauna session at our Forest Bathing Sanctuary (FBS) located on the North Olympic Peninsula, by appointment only. At the FBS in the woods of Blyn, WA, you can reserve a 90-min private sauna for 4 or 6 people, a Private Party Session up to 10 people, or hop in on a shared community session. Our off-grid outdoor bathing sanctuary is equipped with hot and cold outdoor showers, baths, and a large cold-plunge pool all nestled among mature Madrona, Douglas-fir, and Western red cedar forest.
The SeaTsu Sauna experience at our the FBS offers a natural and forested atmosphere, with unique features including delicious aquifer water for bathing and drinking, a cedar geodesic dome for changing, lounging, small events, or overnight stays, and complimentary fizzy water with herbal extracts and tea. The FBS is completely off the grid and intentionally built by its founders using home-milled salvaged (cedar) or on-site (Douglas-fir) timber.

Sauna bathing in community plays an important role in the health benefits of sauna. New social connection, inclusivity, accessibility, and overall social wellness is the goal of this offering. This session is capped at 8 people with shared access to two wood-fired sauna, hot + cold showers, cold plunge pool, wellness dome, outdoor fire, and seltzer water station with herbal extracts when available. The FBS has a clothing optional policy — we encourage sauna guests to do what feels most comfortable for them. Comfort levels may vary, but mutual respect is honored and expected.
