SaunaLife CL4G - 3-Person Outdoor Cube Sauna with Panoramic Glass
The SaunaLife CL4G brings modern Scandinavian sauna design to your backyard with a stunning 3-person cube sauna featuring a full glass front wall. Step inside and you will find an incredibly spacious interior with over 6'2" of headroom, more than enough for tall bathers to sit comfortably upright. The panoramic tempered glass showcases the wood interior while connecting you visually to your outdoor environment, creating a brighter and more meditative sauna experience than traditional enclosed designs.
Handcrafted in Northern Europe from durable thermo-spruce, the CL4G's hexagonal roof design creates a natural chimney effect: fresh air enters at floor level while stale heat exits through the peak, ensuring consistently comfortable air quality throughout your session. This outdoor cube sauna is engineered for two-person DIY assembly and built to withstand years of exposure to rain, snow, and sun without warping, cracking, or decay.

Description
Model E6 Sauna Barrel
The 3-person SaunaLife ERGO-Series E6 Outdoor sauna barrel was designed and engineered by sauna enthusiasts to be the most comfortable, durable, and attractive barrel saunas you can buy.
Ergonomics – Barrel Sauna Comfort
Bathing comfort cannot be overlooked when investing in an outdoor sauna barrel. The diameter of the barrel and the bench/backrest configuration must be considered. Barrels with a small diameter may be priced lower (less materials), but the tradeoffs are door height, bench comfort, and headroom. Smaller diameter barrels have a tighter arc which can create seating posture challenges, impact standing upright, and require one to duck upon entry and exit. ERGO Series Sauna Barrels benefit from a 6’5” interior height. Due to its large diameter, benches can be ergonomically contoured and formfitting. The generous barrel arc can support an expansive and arched backrest for true lumbar support. Touch and feel were not ignored when selecting the knot-free, silky-smooth grade-A Thermo-Aspen seating material designed to hug most any body size.
Durability – A lifetime of outdoor bathing pleasure
Did you know that Thermo-Spruce lasts up to 2X longer than Cedar wood? Every SaunaLife barrel begins with industry-leading 1.65” thick full-length staves that encapsulate the sauna and provide exceptional thermal resistance (R-value). This chemical-free, eco-friendly wood is dimensionally stable and ideally suited for outdoor saunas. We even build showers out of it! Wood thickness is the theme in the SaunaLife ERGO Series and provides bathers with ergonomically crafted benches and backrests from Thermo-Aspen (1.1” thick and 3-1/2” wide) nearly 50% thicker than most.
Ingenuity - Engineered to exceed expectations
Don’t let the simple design and installation process fool you, the ERGO-Series is jam-packed with barrel sauna innovation. Go ahead and splash the water, these beautiful outdoor spaces are built to thrive with water! It begins with industry-leading 1-7/8” wide and 1/8” thick stainless steel barrel bands that compress the massive staves and create your wellness retreat. Then, a watertight DIY shingle kit (a necessity for every barrel sauna) with side-mounted drip edges provides exceptional rainwater management. Inside the barrels are dual floor drains. One is purposefully placed under the sauna heater for your water-tossing pleasure. A second drain is near the door, where cold plunge or pool water may collect. Should this barrel shift out of level, these dual floor drains have you covered.
Illumination – Inside and out
Illuminating your barrel showcases the beauty of the wood and enhances your sauna experience. Only low-voltage and waterproof LED lighting will do. SaunaLife provides a superior white LED lighting system that is Wi-Fi app-based and allows one to set the ideal scene prior to entering the sauna. A hand-held remote control is also provided for on/off/dim operation. SaunaLife’s white LED fixture is heat and water certified (IP67) and is dotless so it provides an enchanting, even glow. Expandable up to four white fixtures, explore the available E Sconce+ Package which provides two striking out-door LED wall sconces ideal outdoor sauna ambiance. For the ultimate backyard sauna party attraction, consider adding E MOOD Lighting Package for both the inspirational and relaxing visual effects that an infinite range of color affords.
Beauty – A compliment to most any outdoor oasis
SaunaLife sources the highest quality Nordic Spruce and dries it to a rich golden color that accentuates its distinctive grain and rustic tight-knot charm. The barrel interior benefits from ergonomically designed benches and backrests of ultra-smooth Thermo-Aspen, a grade-A wood species that is rich in color, and free from knots. A complimentary bottle of paraffin oil, a natural wax, is provided to enrich and preserve the interior luster.
The MODEL E6 home sauna is designed by SaunaLife and precision-crafted in Northern Europe where sauna bathing is a healthy part of everyday life. Enjoy a lifetime of wellness in your own backyard and Live the SaunaLife!
