SaunaLife Model G4 6-Person Cabin Sauna

Constructed from 1.75-inch thick Nordic Spruce wall beams, the Model G4 uses an interlocking log cabin design that provides structural rigidity and accommodates natural wood expansion. The generous interior dimensions of roughly 78 by 78 inches support a two-tier I-shaped bench layout made from knotless grade-A aspen, which stays comfortable against the skin during high-heat sessions. The inclusion of a full-clear tempered glass front and side windows opens up the interior visually, though it does mean slightly more thermal loss compared to solid wood walls.

This kit arrives with a self-adhesive waterproofing roof system, floorboards, and an IP67-rated waterproof LED lighting system controllable via a Wi-Fi app or remote. Because the package does not include a heater or stones, you will need to purchase a compatible high-output unit separately—typically requiring a professional 240V installation by a licensed electrician. Assembly is designed as a DIY project for two people over a couple of days, relying on pre-cut components and a treated ground frame.
