SaunaLife GL4 Outdoor Sauna Kit

Garden Luxury-Series Outdoor DIY Sauna Kit | Thermo-Spruce | Up to 4 Persons

Modern Scandinavian Design with Luxurious Comfort

The SaunaLife GL4 Outdoor Sauna Kit delivers a premium Scandinavian-inspired outdoor wellness experience, combining modern architectural design with high-end craftsmanship. Its sleek linear structure, integrated eaves, and covered porch create a refined backyard retreat that blends elegance with functionality.

A full bronze tempered-glass front enhances the design while filling the interior with natural light and panoramic outdoor views. Designed for up to four people, the GL4 perfectly balances contemporary aesthetics with traditional sauna comfort and relaxation.

Premium Thermo-Spruce Construction

Crafted from 1.57" thick Nordic Thermo-Spruce, the GL4 ensures superior insulation, structural strength, and long-term durability. This premium thermally modified wood offers enhanced resistance to moisture, decay, and fungi compared to standard timber.

The interior features silky-smooth, knot-free 2-tier ergonomic benches designed for maximum comfort. Its precision interlocking-beam construction allows natural wood movement, ensuring long-lasting stability and performance.

Elegant Interior & Exterior LED Lighting

The GL4 features advanced integrated lighting for a premium atmosphere. A full-width exterior LED strip is recessed into the eaves, producing soft, dotless illumination that highlights the entrance and porch area.

Inside, indirect LED lighting creates a warm, ambient glow that enhances the natural beauty of the wood interior. Both lighting systems are fully controllable via Wi-Fi app or wireless handheld remote, allowing complete customization of your sauna environment.

Engineered for All-Weather Performance

Designed for year-round outdoor use, the GL4 includes metal flashing and self-adhesive roofing felt to ensure maximum water protection and weather resistance in all climates.

Every component—from thermally treated walls to precision joinery—is engineered to maintain a dry, secure, and durable sauna environment throughout the seasons.

DIY-Friendly Installation with Professional Results

The SaunaLife GL4 Outdoor Sauna Kit is supplied as a complete DIY package, including pre-cut Thermo-Spruce components, tempered glass panels, roofing materials, and all required fasteners.

With clear instructions and precision manufacturing, two people with moderate DIY experience can assemble the sauna in approximately two days, achieving professional-quality results without the need for professional installation.
