Curve that turns heads
The G3’s parabolic arch looks incredible in any yard and naturally sheds rain and snow. A recessed front terrace (with benches on both sides) gives you a dry place to cool down, chat, or stack a little firewood if you’re running a stove.
Built to last outside
Thermo-Spruce exterior staves and treated cradles/fascia form a tight, weather-ready shell. Inside, knotless Thermo-Aspen benches and backrests stay smooth and comfortable to the touch for years of daily use.
Light, view, and calm
A bronze-tint tempered glass door brings in soft, natural light. The included dotless white LED kit adds an even glow you can control by app or handheld remote—low-voltage and rated for sauna heat.
