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.

Amazing for family evenings

Installation was straightforward. The heat is consistent and it adds a rustic but refined touch to our backyard space.

Modern look, classic feel

The black thermo-spruce finish gives it a sleek, modern vibe, but the wood-burning heat brings that classic experience we were looking for.

Love the wood-burning heat

It feels like a mini retreat right in our yard. Beautiful craftsmanship and the spruce really elevates the look.

The black spruce is stunning

We’ve had 4 adults in here comfortably. Heats up steadily and holds temp well even on cold nights. The black wood looks incredible.

Simple setup, solid heat

This tub heats up much faster than I expected with wood. We use it 3–4 nights a week. Perfect way to unwind.
