4 Person Garden Luxury Outdoor Sauna Kit – SaunaLife Model GL4 Thermo-Spruce Home Sauna with Glass Front
SaunaLife GL4 Outdoor Sauna Kit
Garden Luxury-Series Outdoor DIY Sauna Kit, Thermo-Spruce, up to 4 Persons
Modern Design with Luxurious Comfort
The SaunaLife GL4 Outdoor Sauna Kit combines Scandinavian-inspired design with premium craftsmanship, creating a contemporary retreat in your own backyard. Its sleek linear form, integrated eaves, and porch deliver both elegance and shelter, while the full bronze tempered-glass front fills the interior with natural light and scenic views. With seating for up to four people, the GL4 balances modern style with traditional wellness.
Premium Thermo-Spruce Construction
Built from 1.57" thick Nordic Thermo-Spruce, the GL4 provides superior insulation, durability, and strong resistance to decay, fungi, and moisture compared to conventional timber. The silky-smooth, knot-free 2-tier benches are ergonomically contoured for comfort, while interlocking-beam construction supports natural expansion and contraction for long-lasting structural strength.
Elegant Lighting, Inside and Out
The GL4 includes a full-width exterior LED strip recessed into the eaves, delivering soft, dotless illumination that highlights the entry and porch. Inside, indirect LED lighting creates a warm, diffused glow that enhances the natural beauty of the wood. Both lighting systems can be controlled via Wi-Fi app or wireless handheld remote, allowing full control over the sauna ambiance.
Built for All Weather
Engineered for year-round outdoor use, the GL4 features metal flashing and self-adhesive roofing felt for strong water protection and reliable performance in all climates. From its thermally treated walls to its precision joinery, every detail is designed to keep the sauna space dry, secure, and stable over time.
Professional Results, DIY Simplicity
The SaunaLife GL4 is delivered as a complete kit including pre-cut Thermo-Spruce, tempered glass panels, roofing components, and fasteners. With clear instructions and precision engineering, two people with moderate DIY skills can assemble the sauna in approximately two days, achieving professional-level results without professional labor.
