SaunaLife GL4 4-Person Outdoor Sauna Cabin Kit

Make space to soothe and recover with the SaunaLife GL4 Sauna. This complete kit comes with all the materials needed to build a premium sauna cabin from floor to ceiling.

A set of ThermoSpruce walls help contain the steamy sauna environment, using a natural heat treatment to amplify the wood’s heat management properties. This treatment also creates impenetrable durability for lasting performance through every season.

The sauna interior is equal parts comfort and luxury, using a contoured bench and backrest to support up to four people. These elements are made from carefully-selected wood that’s knot-free and soft on the skin.

A dotless, dimmable LED light kit adds a customizable ambient glow to the cabin room and exterior. You can adjust the intensity of the glow through the included remote or an app on your smartphone.

The full-length, tempered glass front welcomes natural light and features a bronze tint to soften the sun’s intensity. This combination creates clear views for nature-watching while you enjoy the heat and steam.

his cabin is finished with a built-in ventilation system and rubber roofing that keeps the cabin clean and dry through any weather.

Note: This kit does NOT include a Sauna Heater Package. You can find these items in the Suitable Sauna Heaters menu above.

SaunaLife GL4 Construction

The structures of the SaunaLife GL4 are made from Nordic Thermo-Spruce, a heat-treated wood that resists moisture, decay, and harsh weather conditions much better than standard lumber. This makes the cabin durable enough for year-round outdoor use.

Inside, the benches are built from Thermo-Aspen, designed to stay smooth, knot-free, and comfortable in high heat. The benches are extra thick and ergonomically shaped for durability and ease of sitting or reclining.

The base extends outward to create a small porch, while the tempered bronze glass front, including a full-height door and tall windows, adds light and openness to the interior.

Integrated LED lighting beneath the eaves illuminates the entry, while interior LEDs, controlled by remote or Wi-Fi app, create a warm glow inside the sauna. With its 1.57" thick walls, glass accents, and modern linear design, the SaunaLife GL4 combines Scandinavian durability with contemporary style.
