SeaTsu Sauna

About

SeaTsu runs two wood-fired saunas built from vintage horse trailers on a forest site in Blyn, on the Olympic Peninsula. Between rounds there is a saltwater cold plunge, outdoor showers and a cedar dome for changing. Shared co-ed sessions and a women-only night sit alongside private bookings and overnight stays.

Good to know

• Wood-fired heat: softer, heavier löyly than electric, and the smell of the stove is part of the room.
• Cold plunge available on site: use it between rounds for the classic contrast cycle.
• Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
• Set in nature, away from the city, so bring a car or plan the transfer in advance.
• Mobile operator: the sauna travels, so the location is part of the booking. Check the current site before you arrive.
• Bookable as a private session: rent the room for your group rather than sharing with strangers.
• Mixed sauna: men and women share the room, in every session or on set days.
• Women-only sauna: the venue has a women's side or room, or runs set women-only sessions.
• Nude sauna: some or all sessions are taken without swimwear.
• Swimwear sauna: some or all sessions are taken in swimwear, so pack it.
