The SaunaLife Garden Luxury-Series Model GL4 sauna cabin exhibits exceptional quality and attention to detail throughout. Its contemporary linear design is accentuated by contrasting exterior finishes and an integrated eaves and porch, which create an elegant, set-back appearance. Expansive full front glass provides plenty of natural light and outward views to further enhance the spaciousness of this luxurious environment.

Premium-Quality Materials
The exterior is constructed of exceptionally thick (1.57”) thermally treated spruce, which, in addition to enhancing the natural beauty of the wood grain, far outlasts conventional timber and is much more resistant to the effects of moisture, decay, and fungi. The front of the sauna boasts a full height, tempered bronze glass window and door for unobstructed views. The 2-tiered benching is satin-smooth, knot-free, and follows the contour of your body for maximum comfort.

Elegantly Illuminated
Outside, the SaunaLife GL4 provides gentle illumination of the porch and entry with full width “dotless” LED lighting beneath the eaves to lead you safely to your sauna sanctuary. Inside, indirect LED lighting, controllable by Wi-Fi or hand-held remote, produces a diffuse glow throughout the sauna and highlights the natural beauty of the wood interior.

Built to Withstand Any Weather
The Model GL4 is engineered for any weather conditions. In addition to the thick and durable Thermo-Spruce walls and tempered glass front to contain temperature, this sauna is equipped with roofing and metal flashing for superior water management and a dry interior.

You'll get a confirmation email right away. When your order ships you'll get tracking, and one to two days before delivery our team calls to schedule an appointment.
Lead times vary by model and are listed on each product page. Once it ships, transit is usually 3-7 business days.
Most traditional saunas take about 1-2 full days for two people to assemble. They are designed for DIY assembly and include clear instructions, but they are still a real project and not something you should expect to knock out in an hour or two. Plan on using basic tools like a power drill/driver, level, rubber mallet, and standard hand tools. Infrared saunas are typically much quicker to assemble, usually taking about 3-4 hours with two people. If you want us to assemble it for you, we have assembly services available in select areas.
Anything flat, stable, and free of pooling water. A wooden deck, concrete pad, pavers, or gravel all work. We don't recommend setting it directly on turf.
Most 6–9kW heaters run on 240V and need their own dedicated circuit wired by a licensed electrician. The LED lighting runs on standard 120V. We'll walk you through exactly what your chosen heater needs.
