The SaunaLife GL4 Outdoor Sauna Kit brings Scandinavian sauna tradition to your backyard without requiring a contractor. Two people with moderate DIY experience can achieve professional results in two days. The result is a permanent 4-person cedar retreat — with full bronze tempered glass front, Wi-Fi controlled LED lighting, and 1.57" thick Nordic Thermo-Spruce walls — that would cost 3x the price as a custom build.

Engineered for any weather conditions. The Thermo-Spruce exterior outlasts conventional timber, resists moisture, decay, and fungi, and requires minimal maintenance. This is a backyard investment built to last decades.
