Overview
The Cube 210 is a 4-person modern outdoor sauna with a striking full-height double-glazed glass front panel — perfect for stargazing, sunset watching, or quiet contemplation. The cube design heats quickly and efficiently because there's less unused airspace than a conventional rectangular room. Built on a 40 mm thermo spruce frame with solid-wood stave construction, the Cube 210 blends contemporary styling with the durability needed for outdoor installation. The thick staves are excellent insulators and the exterior remains cool to the touch.
