SaunaLife CL4G: a three person cube sauna kit with a full glass front
The SaunaLife CL4G is a three person outdoor cube sauna kit with a full front wall of bronze tinted glass. It is built from thermo-spruce, which is spruce baked in a kiln so it shrugs off moisture. The wood needs little upkeep. A shingled roof and black painted trim at the front finish the outside. It takes up about 81 by 49 inches of yard. Inside, a shaped aspen bench runs along the back wall with a low step in front and a backrest.
The kit includes the wall staves, the glass front and door, the bench, the vents, the foundation beams, and the LED lights. A white LED light bar dims from your phone or a remote. The heater is not included, so pick one of the 4 electric heater packages on the page, from 6 to 7.5 kW; each comes with its control and stones. A bucket and ladle, the SaunaZone, and wood care oils are optional on the page. Need a seat for four? See the SaunaLife CL5G cube sauna. The SaunaLife CL4G ships from My Cozy Outdoors by flat rate freight with No Sales Tax (except WY) and the full manufacturer warranty.

Rating: 5/5
We purchased the 3-person sauna for our outdoor garden. We chose the cube sauna for the aesthetic and could not be happier.
I assembled by myself except for the 2 large panels (requires a few people). Instructions were good - took me two partial Saturdays to complete and a few hours to unpack and organize in advance of assembly. Had my elec. add a NEMA enclosure on the back for the controller and power for lights and a 2nd panel for the wireless control.
Customer service was excellent

FAQ
How many people fit in this cube sauna?
It is sized for up to three bathers. The interior measures 77.2 inches wide by 41.3 inches deep with 74.8 inches of headroom, and the contoured bench and backrest are cut from knotless Thermo-Aspen for smooth, comfortable seating. The full-glass front keeps the room feeling open even with three people inside.
Will it work in a narrow side yard?
That is where this model shines: the exterior is only 49.2 inches deep while running 80.7 inches wide, so it sits neatly against a fence or house wall without projecting far into the yard. You can compare its shallow footprint against deeper cubes and barrels in our outdoor sauna collection.
What heater options does it take?
The heater selector on this page offers Harvia KIP 6kW packages with built-in or Wi-Fi digital controls, the Harvia Wall 6kW package with built-in controls, and a HUUM DROP 7.5kW kit with the UKU Wi-Fi controller and four boxes of stones. Every option ships with sauna stones, and each package’s price is shown on the selector.
Can it handle rain and snow?
Yes. The kit includes a complete shingle kit with drip rails for superior water management, and the organically thermally enhanced Thermo-Spruce staves naturally resist decay and pests, so the structure is built for year-round outdoor exposure. The bronze-tinted tempered glass front door is weather-rated as well as safety-tempered.
What exactly arrives in the kit?
You receive 42mm Thermo-Spruce walls with 28mm front and back walls, the 8mm tempered bronze glass front, the ergonomic Thermo-Aspen bench and backrest, ventilation components, fascia boards, foundation beams, a montage kit, black-painted front details, and full installation instructions, plus the LED light bar system with its remote, power supply, and mounting hardware.
How is the sauna lit?
A white LED light bar with Wi-Fi app control is part of the package, along with a wireless handheld remote and mounting cradle. It runs on low-voltage 24-volt DC power for bathing safety, uses IP67 water- and heat-rated connections, and can be expanded to control up to four white LED light sources later.
