Description
Crafted with unmatched precision in Northern Europe, the SaunaLife Model S4B Soak‑Series elevates outdoor hot tub excellence. It arrives fully assembled and ready for action—no electricity needed—making it a perfect eco‑friendly retreat.
This six-person tub features a sleek black Thermo‑Spruce exterior, naturally enhanced to resist rot and weathering, and lasts up to twice as long as cedar. Inside, a thick, contoured fiberglass shell offers ergonomic comfort and is designed for effortless cleaning.
The heart of the S4B is its high-efficiency wood-burning stove, engineered with a dual-chamber, self-cleaning design that captures smoke heat and reduces wood use by up to 50%, while heating 304 gallons of water from 40°F to 95°F in just 1.5 to 2 hours—three times faster than traditional models.
The tub includes thoughtful features such as Thermo‑Spruce steps, a marine‑grade vinyl cover, a foldable insulated foam lid, a stainless steel chimney, and an integrated drain tap. It holds up to six bathers and delivers superior relaxation in style.
