SeaTsu was inspired from the Finnish word "SISU" (see-soo). Sisu is an inner way of being that channels determination, grit, courage, resilience, and inner strength.
Sisu is within all of us, and we believe sauna + cold-plunge helps it come alive!
Co-creators of SeaTsu
Kurt & Lusa Langski
SeaTsu was also born out of love & respect of the Sea & Forest and the inherent strength in both of these forces.
Shout out to Tsuga spp. (Hemlock species), Pseudotsuga menziesii (Douglas-fir), Arbutus menziesii (Pacific madrone) - an exceptionally amazing firewood when cured, and of course...to the sacred Thuja plicata (Western redcedar) which we use to line the interior of our sauna builds.
Mobile sauna is popping up all over the US, Canada, UK, NZ, Ireland…the list goes on. Just hashtag mobile sauna and join the community. For us, the idea for a mobile sauna was born in 2017 when a friend expressed how they would love to turn an old horse trailer into a sauna – “so you could take it with you wherever you wanted...". Just think about the cold-plunge opportunities...that sort of thing was right up our alley. Less than a year later, Kurt came home with a 1953 Trailer King horse trailer. There was no turning back - we began building a wood-fired sauna on wheels.
In July 2022 we finished our second horse box sauna ‘Sea Wolf’🐺🌊 simultaneously working other jobs and offering sauna service with the Royal Steam. Kurt and Lusa are big proponents of DIY and creative building, especially with reclaimed materials. We built both of our mobile sauna’s with local Western redcedar that we salvaged and milled ourselves, and a lot of the other materials were scrapped and reused. Same goes for the Forest Bathing Sanctuary that we are continuously improving on (until we find a new location...) to offer this experience to the public on a regular basis.
Lusa & Kurt established SeaTsu Sauna, SPC in 2021 with a commitment to provide more access and stoke for thermic bathing culture & hot+cold contrast therapy in Nature. Through this endeavor, we strive to provide a service that strengthens health and wellness among planet and community.
the seatsu sauna
Each sauna is heated by a commercially produced Finnish sauna stove, which has been appropriately sized for the sauna room.
We curate the wood-stove in the sauna to keep an ideal temperature range of 160-200°F throughout your session. A small bundle of wood is provided to maintain a comfortable range at your leisure.
Our sauna and the experience we promote is styled according to Finnish sauna standards. We encourage our guests to experience multiple sessions of heat-cool-relax.
The SeaTsu Forest Bathing Sanctuary features outdoor hot/cold shower, hot bath tubs, saltwater cold-plunge pool, outdoor fire pit, and an 20’ cedar geodesic dome (plans by Trillium) with woodstove for changing area, overnight retreats, and peaceful indoor lounge space.
Blyn, WA is colonized S’Klallam land. We are located just up the road from the Jamestown S’Klallam Tribal Center.
S’Klallam is a Salish term for “the strong people” – self-reliant and determined to forge one’s own path. We honor the S’Klallam way by forging a path with authenticity, resourcefulness, and a strong commitment to foster harmony, wellness, and healing with Nature.
The “Royal Steam” sauna originated as a 1953 Trailer King horse-box. Repurposing the strong frame of a horse trailer and honoring the vintage patina on the outer shell that only time can create. On the inside, the Royal Steam features an inviting artistic design from unique home-milled cedar boards from surrounding forest.
Every sauna has a soul, and the Royal Steam’s is strong! We invite you to enjoy this matchless experience at our Forest Bathing Sanctuary in Blyn.
We have now finished our second horse box sauna to share double the heat on Thermic Thursday Community Sauna, or enjoy it seaside as a pop-up event or simply overnight as Private Home Rentals. We also love to collaborate with other businesses and local events!
the COLD PLUNGE
Hot - Cold - Rest - Repeat
Our saunas are best used in conjunction with cold water. This 1000-gallon repurposed baptismal tub supports your sauna cycling when you visit us at the Forest Bathing Sanctuary.
Cold water immersion is known for increasing dopamine and serotonin levels instantly and remaining elevated for several hours following. Our cold-plunge pool is filled with some of the finest aquifer water on the peninsula and is serviced daily. Guests are required to rinse off before plunging!
Sweating is one of the most effective methods of destressing and detoxing the body from toxins such as heavy metals, pesticides and other harmful chemicals. Regular sauna use is also associated with a 50% lower risk of cardiovascular disease and all-cause mortality. Saunas are generally safe for most people, but it is advised to check with your doctor first if you have high blood pressure, heart disease, or are pregnant.
Some benefits of sauna bathing include, but are not limited to:
detoxification, increased blood circulation, pain reduction, anti-aging, skin rejuvenation, muscle tension & stiff joint relief, improved cardiovascular function, increased metabolism, improved immune function, improved sleep, stress reduction, and total relaxation.
SeaTsu wood-fired sauna is a natural, wholesome and joyful experience. It is a welcome compliment to the complex, techy, and stress-ridden aspects of daily life. Don't hesitate, meet us at the Blyn Woods Forest Bathing Sanctuary, & feel the benefits yourself!
