The piece
The Model S1N is a solo immersion tub for both the cold plunge and the warm soak, finished in natural Thermo-Pine over a contoured fiberglass liner. It arrives fully assembled, ready to take its place beside your sauna.
Cold, or warm, as the day requires
The Model S1 is a compact round vessel, about forty inches across, built for one and equally suited to a bracing cold plunge after the sauna or an unhurried warm soak. Its 36-inch interior depth allows a full-shoulder immersion.
Standard 3/4-inch NPT connections let you add a chiller or heater later, whenever you are ready.
Thermo-Pine craftsmanship
Its natural Thermo-Pine exterior carries a warm, honey-brown tone that settles easily into a garden, deck or spa terrace.
Thermally modified pine is heat-treated for stability outdoors, and SaunaLife rates it at up to twice the lifespan of cedar, with good thermal resistance to help hold water temperature.
Comfort within
A thick, contoured fiberglass liner is shaped to support the body, and it is easy to keep clean. The tub rests on 3.94-inch foundation beams and drains through a one-inch outlet.
Arrives ready
Each tub is delivered fully assembled with matching Round Deluxe Stairs, and is covered by SaunaLife's limited lifetime warranty. An insulated cover, sold separately, is recommended to keep the water clean between sessions.
