SaunaLife Cube-Series Model CL4G
The SaunaLife Cube-Series Model CL4G is a 3-person outdoor sauna that brings contemporary Scandinavian design and premium Northern European craftsmanship together in one striking backyard structure. Wider and more spacious than the CL3G, the CL4G accommodates up to 3 bathers with ease — all beneath the same dramatic full-glass front wall that makes the Cube Series instantly recognizable.
At 80.7" wide with an interior over 6'2" tall, the CL4G's proportions feel genuinely open and comfortable rather than cramped. The floor-to-ceiling 8mm tempered bronze glass front floods the interior with natural light and creates a seamless visual connection to your outdoor surroundings, making every session feel like an extension of the landscape around you. Inside, ergonomically contoured Thermo-Aspen benches and an arched backrest are shaped to support the body through long, restorative sessions — satin-smooth to the touch and naturally cool against the skin even in intense heat.
The exterior is built entirely from organically thermally enhanced Thermo-Spruce: stronger and more dimensionally stable than conventional wood, naturally resistant to decay and pests, and built to endure years of outdoor exposure without compromise. Full-length 42mm wall staves form the structural shell, while a complete shingle roof kit with drip rails manages water effectively and keeps the interior dry in all weather. All front details are finished in black for a sharp, modern aesthetic. A Wi-Fi-controlled white LED lightbar is included and ready to use from day one. Note: a sauna heater is required for operation and is sold separately.
