Model CL4G Outdoor Home Sauna Kit
Most outdoor saunas look good in a showroom and start showing their age within a few seasons. The CL4G is different. It is built from the same thermally treated Nordic materials used in Scandinavian construction wood that has been heat-treated to become genuinely stronger, denser, and more resistant to moisture and pests than untreated cedar or pine. It will not warp, it will not split, and it will not need repainting.
The full-glass front changes everything
Most saunas feel like a dark box. The CL4G does not. The entire front wall is 8mm tempered bronze glass which means once you are inside, you are looking out at your backyard, your trees, your sky. That view transforms a 20-minute session into something you actually look forward to. The bronze tint keeps things private from the outside while remaining bright and open on the inside.
Comfort that does not make you rush
The benches and arched backrests are made from knotless Thermo-Aspen a wood that stays cool to the touch even when the sauna is running at full heat. No hot spots, no awkward shifting. The ergonomic backrest angle was specifically designed for long sessions. Pair that with the engineered airflow system that keeps heat consistent from floor to ceiling, and you have a sauna that rewards you for staying in, not for getting out.
Set it up once, use it for decades
The CL4G ships as a complete kit and assembles in a single day with two people and basic tools. No contractor, no concrete foundation, no special electrical work beyond a standard 220–240V hardwired connection. Once it is up, a shingled roof with drip rails handles rain and snow year-round. The Thermo-Spruce exterior needs no staining or sealing just an occasional wipe-down. It is built to be used, not maintained.

About SaunaLife
The standard for DIY outdoor saunas
SaunaLife was built by people who believed a world-class outdoor sauna should not require a contractor, a massive budget, or a compromise on quality. By partnering with Nordic craftsmen and using thermally treated Northern European wood throughout, they created a product that competes with custom installs at a fraction of the price.
Every SaunaLife cabin is covered by a lifetime structural warranty. If something fails due to a factory defect, they repair or replace it no questions asked. That is the confidence that comes from building something right from the start.
