SaunaLife GL4 Garden Luxury Outdoor Sauna Kit — 4 Person Thermo-Spruce

Transform Your Backyard Into a Modern Wellness Retreat

Experience true Scandinavian craftsmanship with the SaunaLife GL4 Outdoor Sauna Kit — a luxurious 4-person sanctuary designed for beauty, durability, and everyday rejuvenation. Its sleek Garden Luxury Series architecture features integrated eaves, a front porch, and a stunning full-height bronze tempered-glass façade, creating a bright and inviting escape right in your backyard.

Built for year-round performance, the GL4 blends modern European design with traditional sauna warmth, offering the perfect balance of style, wellness, and natural comfort.

Premium Thermo-Spruce Craftsmanship

The GL4 is constructed from 1.57″ thick Nordic Thermo-Spruce, a thermally treated wood renowned for its strength, insulation, and resistance to rot, fungus, and warping. The solid interlocking-beam design ensures stability, while the silky-smooth, knot-free benches are contoured for ergonomic comfort and longevity. Every element is precision-engineered to deliver decades of relaxation and health benefits.

Brilliant Lighting, Inside and Out

Enhance your sauna’s atmosphere with dual-zone LED lighting:

• A recessed exterior eave strip casts a soft, dotless glow over the entryway.

• Indirect interior lighting creates a calming ambiance that highlights the natural grain of the spruce.

Both lighting systems are Wi-Fi app and remote controlled, allowing you to adjust brightness and mood from anywhere.

Built to Withstand Every Season

The GL4 is engineered for all-weather durability, featuring precision joinery, metal flashing, and self-adhesive roofing felt to seal out rain and snow. From its robust Thermo-Spruce panels to its advanced ventilation and drainage system, this sauna is crafted to remain dry, efficient, and beautiful through every season.

DIY-Friendly Assembly — Professional Results

Delivered as a complete pre-cut kit, the GL4 includes everything you need for easy assembly. With two people and moderate DIY experience, you can build your sauna in as little as two days, achieving professional-grade results without the labor cost.
