Sunray Grandby 3-Person Infrared Sauna

Constructed from solid Canadian hemlock, the Sunray Grandby uses tongue-and-groove panels designed to handle standard backyard conditions while maintaining a clean, natural wood finish inside and out. The cabin incorporates seven rapid-heat ceramic heaters that emit far-infrared warmth, getting the interior up to its maximum 140 degrees relatively quickly without requiring a professional electrician. Because it operates on a standard 120V, 20-amp circuit, installation is much simpler than traditional high-voltage rock-and-heater steam setups, though you will need a dedicated 20-amp outlet to prevent tripped breakers.

Inside, the cabin provides a 55-inch interior width and a 43-inch interior depth, giving three people enough room for side-by-side bench seating during a standard sweat session. Taller users should note the 68-inch interior height, which means you will be sitting rather than standing. Additional features like a Bluetooth sound system, recessed lighting, and an oxygen ionization system come standard, making this a self-contained unit that prioritizes convenience and comfort for everyday backyard use.
