The Slimmest Footprint in the Cube-Series — Modern Glass-Front Design for Tight Spaces.
The SaunaLife Cube-Series Model CL4G is the most space-efficient entry into SaunaLife's modern cube sauna lineup — built for narrow patios, side yards, and compact backyards where the larger CL5G's 63-inch depth simply won't fit. At just 49.2 inches deep, the CL4G delivers the same 80.7-inch width and over 6 feet 2 inches of interior headroom as its larger siblings, with the same bright, airy full-glass-front design that defines the Cube-Series aesthetic. Contoured Thermo-Aspen seating with supportive arched backrests stays cool to the touch through extended sessions, while the bronze-tinted tempered glass door adds both safety glazing and a refined, contemporary look. Built from durable Thermo-Spruce — 42mm side walls and 28mm front and back walls — the CL4G resists decay and pests without chemical treatment, finished with a complete shingle kit and drip rails for effective water management. 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. Foundation beams, ventilation, and a complete montage kit are included for a full, ready-to-build package. Backed by SaunaLife's Limited Lifetime Warranty and precision-handcrafted in Northern Europe, the CL4G proves that a small footprint doesn't mean a small experience.

Who This Is For
The CL4G is the right choice for buyers with the tightest outdoor footprints — narrow side yards, compact patios, or properties where the CL5G's 63-inch depth doesn't fit — who still want the full Cube-Series modern glass-front aesthetic, Thermo-Spruce durability, and included Wi-Fi LED lighting. It suits solo users and couples who don't need the CL5G's larger bench depth, design-conscious buyers prioritizing the architectural look of the Cube-Series over maximum interior space, and anyone for whom the included foundation beams and ventilation make for the most complete out-of-box kit in the lineup.
Frequently Asked Questions
Q: What is the difference between the CL4G and the CL5G?
A: Depth and bench configuration. The CL4G is 49.2 inches deep with a 41.3-inch interior depth and a slim 8.3-inch lower bench, while the CL5G is 63 inches deep with a 55.1-inch interior depth and a much larger 31.1-inch lower bench plus a 23.6-inch side bench. Both share identical 80.7-inch width, 74.8-inch interior headroom, Thermo-Spruce construction, full glass front, and included Wi-Fi LED lighting. The CL4G is the choice when depth is the limiting factor; the CL5G is the choice when more seated bench space is the priority.
Q: Is the CL4G suitable for more than one person?
A: Yes — while more compact than the CL5G, the 77.2-inch width and 41.3-inch interior depth provide comfortable seating for 2 people on the top bench, with the lower bench offering additional footrest or seating space. The 6'2" headroom remains identical to the larger Cube-Series models, so the compact footprint doesn't compromise vertical space.
Q: Does lighting come included or is it an upgrade?
A: Included as standard. The CL4G ships with a complete White LED Light Bar System — Wi-Fi app control, wireless handheld remote, IP67-rated waterproof wiring, 24V DC operation, and a 30-foot light cable. Expandable to up to four light sources via the optional E SCONCE+ package.
Q: What foundation does the CL4G require, and is anything included to help?
A: A level, stable, load-bearing surface — concrete pad, compacted gravel, or reinforced deck — sized to the 80.7"×49.2" footprint. Unlike some Cube-Series models, the CL4G kit includes foundation beams as standard, simplifying the base preparation process alongside the included montage kit and installation instructions.
Q: Does it come with a heater?
A: No — an electric sauna heater sized for the CL4G'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.
