ThermaSol Nordic Misty Small 2–5 Person Outdoor Sauna Cabin with Wood-Burning Heater

The Nordic Misty brings Scandinavian sauna design to your backyard, heated the traditional way with wood. The Small cabin seats two to five people and arrives assembled, so setup on site comes down to placing the cabin and installing the heater, chimney and door handles.

The exterior is dark Nordic heat-treated spruce, surface-treated at the factory to resist UV and dirt. Inside, heat-treated aspen gives the room a smooth, warm finish that stands up to moisture. A tinted glass wall lets in natural light while keeping the space private, and LED lights under the bench and along the backrest add soft ambient light. The benches lift for easy cleaning.

A Harvia Legend 150 wood-burning heater warms the cabin. Its steel frame holds up to 120 kg (265 lbs) of stones, and the heater needs no electrical connection. The package includes a pre-dimensioned steel chimney with a rain flange and rain cap, a Harvia WL300 smoke pipe guard, protective bedding, a hearth plate, safety rails, 8 boxes of Harvia AC3020 sauna stones and the Onyx Deluxe Accessory Kit with a stainless steel bucket, ladle and thermometer/hygrometer.

The glass door has an adjustable roller latch, wooden handles and an external lock with a padlock and 2 keys. Drainage and ventilation are built in. Screw connections let you add other Nordic Misty modules, such as a lounge, changing room, terrace, privacy fence or pergola, to build a larger outdoor wellness space.

Installation note: The sauna ships assembled by flatbed. Lift it with a forklift (2 m forks, entering from the front) or a crane with slings set front to back, never from the side. Place it on a stable, level foundation, never directly on the ground: concrete slabs topped with roofing felt or screw piles both work. Keep tall grass away from the base so the lower parts stay ventilated, and plan for the drain outlet at the back wall. Before installation, preheat the Legend heater outdoors on a non-combustible base to burn off its protective coatings. Install the heater on the protective bedding, then fit the smoke pipe, guard, insulation and steel chimney through the roof and seal the rain flange with silicone. Keep a non-combustible area in front of the heater, and check that the chimney is clear of flammable structures and meets your local fire and building codes. The LED lights plug into a socket under the sauna. Customers are notified two weeks before delivery. For complete guidelines, refer to the product manuals.
