SaunaLife CL4G 3 Person Outdoor Cube Sauna

Spacious 3 Person Layout

The CL4G is designed for up to 3 bathers, giving you more room than a compact 1–2 person sauna while still fitting beautifully into smaller outdoor spaces.

Modern Scandinavian Cube Design

The clean cube silhouette creates a contemporary backyard sauna presence that feels refined, architectural, and timeless.

Premium Thermo-Spruce Construction

The sauna walls and exterior are built from Thermo-Spruce, a thermally enhanced wood selected for outdoor durability, dimensional stability, and long-term performance. SaunaLife notes that Thermo-Spruce is stronger, more dimensionally stable, and naturally resistant to decay and pests compared with conventional wood.

Comfortable Thermo-Aspen Seating

Satin-smooth Thermo-Aspen benches and backrests provide a comfortable, cooler-to-the-touch seating surface for longer sauna sessions.

Full Bronze-Tempered Glass Front

The expansive glass front wall creates a bright, airy interior feeling and opens the sauna visually to the outdoors. SaunaLife lists the CL4G with a tempered bronze front glass wall.

WiFi-Controlled LED Lighting

The included white LED light bar system includes WiFi app-based operation, a wireless handheld remote, mounting cradle, power supply, driver, cable, clips, and installation instructions.

Traditional Sauna Performance

Pair the CL4G with a Harvia or HUUM electric sauna heater to enjoy authentic Finnish-style heat, heated stones, and water-pouring löyly.

Expert Support from NW Immersion

Our team helps with heater selection, delivery planning, electrical questions, installation guidance, and long-term ownership support.
