SaunaLife Garden Luxury-Series Model GL4B Outdoor Garden Luxury Sauna
4-Person | Glass Front | Thermo-Spruce | Black Finish — Paint Included | Handcrafted in Northern Europe
Engineered for pro-quality DIY sauna installation | 2 people | 2 days
The SaunaLife Garden Luxury-Series Model GL4B Outdoor Garden Luxury Sauna is a 4-person outdoor sauna cabin with a contemporary linear design, integrated eaves and porch, and an expansive full-front glass wall for natural light and outdoor views.
The Model GL4B features interlocking Thermo-Spruce panels, extra-thick two-tier thermo-hardwood benches, and a full bronze tempered-glass front with a full-height door pull. Its contemporary design creates a refined backyard sauna setting.
Lustrous Black Finish
The Model GL4B includes two 2.7 L containers of specially formulated PROSAUNAS SaunaShield Black Sauna Paint. SaunaShield is designed for outdoor sauna exteriors and expands and contracts with changing temperatures. Apply the included paint on site to create a contemporary black finish.
Premium Materials
The exterior is constructed from 1.57-inch thermally treated spruce. The full-height tempered bronze glass window and door provide outward views, while the two-tiered benches are made from satin-smooth, knot-free Aspen wood.
Lighting
Full-width dotless LED lighting beneath the eaves illuminates the porch and entry. Inside, indirect LED lighting creates a diffuse glow throughout the sauna. The lighting system can be controlled by Wi-Fi app or handheld remote.
Outdoor Weather Protection
The GL4B is designed for outdoor conditions with thermally treated spruce walls, a tempered glass front, roofing, and metal flashing. These components support water management and help keep the sauna interior dry.
A compatible sauna heater is required for operation and is sold separately.
Who This Is For
The Model GL4B suits homeowners who want a well-appointed outdoor cabin sauna with premium materials and room to relax — a great fit for couples, families, or anyone creating a backyard spa retreat at home.
