Premium 4-Person Outdoor Scandinavian ThermoWood® Cube Sauna Kit With LED Lighting [MW16] (SAK25470)

Description

Why This One

The Outdoor Sauna That Gets Better Every Year

Solid 1.7" European ThermoWood® Spruce. Tempered glass architectural front. Integrated LED lighting. A cube design that looks completely intentional in any backyard.

This is the outdoor sauna kit built from material that genuinely improves with age and weather.

Step Outside. Close the Door. The World Can Wait.

Your backyard becomes a different place the moment the heat rises. The rich, warm scent of ThermoWood® surrounds you. The glass front frames whatever view you have chosen to face. The LED light settles into a soft glow. Everything that was loud a moment ago goes quiet.

This is what the MW16 is built for.

ThermoWood® Is Not Just a Name

Every panel of this outdoor sauna cabin is milled from European Spruce that has been thermally modified using only steam and high heat, no chemicals, no preservatives, no toxic additives of any kind.

That process changes the wood at a cellular level. It becomes dramatically more resistant to moisture, decay, and insects than untreated timber. It stops expanding and contracting with humidity. It deepens to a warm, rich tone that weathers beautifully outdoors and never needs staining or sealing to stay protected year after year.

The result is a backyard sauna structure that is cleaner to breathe in, longer-lasting than pressure-treated alternatives, and genuinely low maintenance. The air inside stays pure even at peak temperatures because there is nothing in the wood to off-gas. That is the promise of ThermoWood®, and it is why this outdoor sauna kit earns its price.

Four People. Two Levels. One Beautiful Ritual.

The MW16 seats four adults comfortably. In practice, that means two people can stretch out fully on the wide Scandinavian benches, or a small group can share a session together without feeling crowded.

The two-level sunbed bench configuration gives you options. Recline on the upper bench at higher heat for a deep, restorative session. Settle onto the lower bench for something gentler. At 62" wide, both benches are long enough to lie completely flat, the kind of full-body surrender to warmth that a studio sauna simply cannot offer.

The tempered glass front wall keeps the interior connected to the outdoors. Whether your outdoor sauna faces a garden, a treeline, or an open sky, the view becomes part of the ritual. Integrated LED lighting makes early morning and evening sessions equally effortless. The contemporary cube profile is clean and geometric, a backyard structure that elevates the space it occupies.

Heat Your Way

The MW16 is available with a Harvia KIP 8.0KW electric heater in black or silver, or without a heater if you prefer to source your own. The Harvia KIP is a proven, compact Finnish electric sauna heater with a built-in controller, purpose-designed for cabins of this size.

Traditional wet or dry heat. Pour water over the stones for löyly-style steam and the full Scandinavian sauna ritual, in your own backyard. Adjust the temperature from the built-in controller. The ritual is simple because the equipment is exactly right.
