Wood-fired Sauna Service & Mobile Rental
Serving the North Olympic Peninsula & beyond
SeaTsu welcomes the public to enjoy a 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 session for up to 4 people, or 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 redcedar trees.
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.
