Model CL5G Outdoor Home Sauna Kit
The SaunaLife CL5G is the Cube Luxury Series model that most buyers land on and for clear reasons. At 77.2 inches wide and 55.1 inches deep on the interior, it gives four adults genuine room to sit without crowding, a lower bench that extends across both walls at 31.1 inches deep and over 6 feet long for anyone who wants to lie down, and an interior height of 74.8 inches that accommodates every bather upright without adjustment. The full 8mm bronze-tinted tempered glass front wall floods the space with natural light and frames an unobstructed outdoor view from every seat. It is not the smallest Cube or the largest. It is the one that gets the balance of space, presence, and practicality exactly right.
The full glass front wall and why it defines the Cube Series
What sets the Cube Luxury Series apart from every other outdoor sauna category is the glass front and the CL5G delivers it fully. The entire front face of the sauna is 8mm bronze-tinted tempered glass, including the door. From outside, the bronze tint reads as warm, private, and architectural at any hour of the day. From inside, the glass disappears and what remains is a direct, unobstructed view of whatever lies beyond the front of the sauna a garden, a pool deck, a treeline, a winter landscape. Sessions that would feel enclosed in a solid-walled sauna feel connected and spacious in the CL5G. At 80.7 inches wide on the exterior, the glass front is wide enough to make a genuine statement in any backyard, and striking enough at night when the dotless LED lighting glows through it to become the focal point of an outdoor space.
A bench layout designed for how people actually use saunas
The CL5G's bench configuration is one of its most thoughtfully designed features. The top bench runs the full back wall at 76 inches with a 17.7-inch depth the primary seating position for four bathers. Below it, the lower bench extends all the way across both the back wall and the side wall, reaching 31.1 inches deep and 73.2 inches long on the back: enough for a bather to stretch out flat in the steam zone, which is the position closest to peak heat and löyly intensity in a traditional sauna. A separate side bench at 23.6 inches deep gives additional seating flexibility. Every surface is knotless Thermo-Aspen satin-smooth, splinter-free, and cool to the touch at full operating temperature. The arched ergonomic backrest supports the natural curve of the spine for sessions of any length.
1.7-inch Thermo-Spruce walls built to outlast cedar outdoors
The CL5G's exterior staves are 1.7 inches thick and cut from full-length Nordic Spruce that has been thermally treated under pressurized heat and steam without any chemical preservatives. The process densifies the wood cell structure, eliminates the sugars fungi feed on, and makes the wood naturally resistant to moisture, insects, and dimensional movement through years of outdoor heating and cooling cycles. The result is a wall material that outlasts cedar in real outdoor conditions and requires no staining, sealing, or repainting over the lifetime of the sauna. A double-layer shingle roof with integrated drip rails handles rain and snow year-round. Engineered airflow ventilation — fresh air enters below, stale heat exits at the top keeps the temperature even throughout the interior with no dead zones.
The most popular outdoor sauna kit in the Cube Luxury Series. The CL5G gives four bathers over 6'2" of standing height, a full bronze glass front wall, 1.7-inch thermally treated Nordic Spruce walls, and a lower bench generous enough to lie down in the steam zone all in a backyard-ready package that assembles in a day and requires no ongoing maintenance.

About SaunaLife
Built where sauna is a way of life.
SaunaLife was founded by a group of sauna enthusiasts who believed that a world-class outdoor sauna should not require a contractor, a massive budget, or any compromise on quality. By partnering directly with Nordic craftsmen in Northern Europe Estonia, one of the original sauna countries and building with the same thermally treated spruce used in Scandinavian outdoor construction for generations, they created a product line that consistently delivers on every promise the category makes and rarely keeps.
Every SaunaLife Cube ships as a complete, numbered DIY kit designed for two people and basic tools, assembled in a single day. The Thermo-Spruce exterior needs no maintenance beyond an occasional wipe-down. The entire cabin structure is covered by a lifetime warranty if a factory defect appears at any point, SaunaLife repairs or replaces the affected parts at no cost to you, no questions asked.
