Outdoor Cube Saunas

Outdoor cube saunas — architectural glass meets Nordic engineering

The cube sauna is what European spa-resort architects build when budget isn't the primary constraint. Floor-to-ceiling tempered glass on three faces, matte-black thermo-treated exterior, L-bench layout for true social steam. The Norhelm is our flagship — 4 adults reclined or 6 upright.

Cube saunas demand more from the foundation (a 100×82 inch level pad) and from the electrical (240V/40A dedicated circuit hardwired) but the result is the most photogenic backyard structure you can install short of a custom architecture build. Premium Nordic Spruce exterior 42mm thermo-treated with zero-VOC matte-black oil finish; Canadian Hemlock interior 19mm tongue-and-groove with food-grade tung oil.

This is the flagship-tier choice. If you want a steam ritual with a view, and you have the property to host it, this is the cube. Read our year-round care guide before installation — it covers the foundation prep, the seasonal maintenance, and what to watch for in the first year.
