Modern Cube Architecture. Full Glass Front. The Right-Sized Entry Into SaunaLife's Cube-Series.
The SaunaLife Cube-Series Model CL5G is the 4-person entry point into SaunaLife's modern cube sauna lineup — combining the same sleek, full-glass-front Scandinavian design language as the larger CL7G in a more compact footprint suited to smaller backyards, patios, and side-yard installations. Over 6 feet 2 inches of headroom gives the cabin an open, uncramped feel rarely found in saunas at this size, while contoured Thermo-Aspen benches with supportive arched backrests and satin-smooth, cool-to-the-touch surfaces are engineered for genuinely extended sessions. The exterior is built from durable Thermo-Spruce — full-length staves at 1.7 inches thick on the side walls and 28mm on the front and back — thermally modified to resist decay, pests, and weathering without chemical treatment, finished in a darker, low-maintenance tone with excellent stability and strength. A complete shingle roof kit provides superior water protection, and the tempered bronze glass front wall and door flood the interior with natural light while framing the outdoor view. A White LED Light Bar System with Wi-Fi app control comes included as standard — dotless white glowing lighting, a wireless handheld remote, IP67-rated waterproof connections, and a 30-foot light cable, expandable to four light sources via the optional E SCONCE+ package. Backed by SaunaLife's Limited Lifetime Warranty and precision-handcrafted in Northern Europe, the CL5G delivers the Cube-Series design statement at the scale most backyards actually need.

Who This Is For
The CL5G is the right choice for homeowners who want the Cube-Series' modern, full-glass aesthetic and Thermo-Spruce durability at a 4-person scale that fits smaller outdoor spaces, buyers who want smart Wi-Fi lighting included rather than purchased as an add-on, couples and small families who don't need the CL7G's larger 6-person footprint, and design-conscious buyers who want a sauna that reads as architecture rather than a rustic cabin. If the CL7G is the statement piece for larger properties, the CL5G brings the same design language to backyards of every size.
Frequently Asked Questions
Q: What is the difference between the CL5G and the CL7G?
A: Capacity and footprint. The CL5G seats up to 4 persons in a 77.2"×55.1" interior with 74.8 in (6'2") headroom and an 80.7"×63" exterior. The CL7G seats up to 6 persons in an 87.5"×70.8" interior with 85.5 in (over 7 ft) headroom and a larger 91"×86.6" exterior, and uses facing-bench social seating versus the CL5G's more compact configuration. Both share the Cube-Series full-glass-front design and Thermo-Spruce construction. The CL5G is the right-sized choice for smaller properties and 2-4 person households.
Q: Does lighting come included or is it an upgrade?
A: Included as standard. The CL5G ships with a complete White LED Light Bar System — Wi-Fi app control, wireless handheld remote, IP67-rated waterproof wiring, 24V DC operation for bathing safety, and a 30-foot light cable. It's expandable to up to four light sources via the optional E SCONCE+ package for enhanced ambiance.
Q: How does Thermo-Spruce compare to standard Nordic Spruce for this exterior?
A: Thermo-Spruce is thermally modified through a chemical-free heat-and-steam process, producing a darker-colored, splinter-resistant, low-maintenance wood with excellent stability and strength — increased durability versus untreated Nordic Spruce without requiring annual staining or chemical treatment for decay and pest resistance.
Q: Does it require a heater, and is one included?
A: No heater is included. An electric sauna heater sized for the CL5G's interior volume is required and sold separately. Compatible heater options are available at HomeUpgradeDirect.
Q: What does the Limited Lifetime Warranty cover?
A: SaunaLife's Limited Lifetime Warranty covers factory-assembled components found defective in workmanship under normal residential use for the lifetime of the sauna. It does not cover normal material wear, natural weathering of the lumber, shipping/installation costs, or sauna heaters and added components. The warranty is voided by commercial use, unauthorized repairs, or operation outside designed parameters.
Q: What foundation and assembly does the CL5G require?
A: A level, stable, load-bearing foundation — concrete pad, compacted gravel, or reinforced deck — sized to the 80.7"×63" exterior footprint. The kit includes a montage kit and installation instructions for assembly; an electrician is recommended for the heater circuit installation.
