4-Person Sauna with Glass Front
The SaunaLife GL4 brings high‑end Scandinavian design to your backyard. Its contemporary lines and integrated porch create a set‑back, architectural silhouette, while a full bronze‑tempered glass front bathes the cabin in natural light and makes the 4‑person interior feel more spacious. Black accent trim and a dot‑less LED strip under the eaves give this sauna a distinctly modern look.
Premium materials
Constructed from exceptionally thick 1.57″ thermally modified spruce, the GL4 outlasts conventional timber and resists moisture, decay, and fungi. The full‑height tempered glass door and window provide unobstructed views and complement the warm Nordic spruce. Inside, two tiers of knot‑free, ergonomically contoured benches invite you to stretch out and relax.
Elegantly illuminated
A full‑width, dot‑less LED strip beneath the eaves guides you safely to your sauna. Inside, indirect LED lighting controlled via Wi‑Fi or a hand‑held remote produces a diffuse glow that highlights the natural beauty of the wood.
Built for any weather
Thick thermo‑spruce walls and tempered glass retain heat, while an insulated roof, metal flashing, and a proper drainage system keep the interior dry. The interlocking beam construction allows natural expansion and contraction and ensures a weather‑tight seal.
Pro results in two days
The GL4 ships as a complete DIY kit with pre‑cut walls, roof and floor sections, benches, backrests, tempered glass, porch boards, insulation, and all necessary fasteners. Two people with moderate DIY experience can assemble it in about two days. We supply detailed instructions and support to guide you from foundation prep to first heat.
