A Better Way to Sauna.
Engineered for fast heat, natural light, perfect steam, and true portability.
The NorthUp Difference
Traditional saunas are built around the limitations of wood: slower to heat, dark interiors, less efficient at distributing heat and steam, and fixed in place.
The entire structure is engineered so you can use your sauna spontaneously, not just when planned.
- Sunlight alone can warm the interior up to 75°F above ambient before the stove is on.
- The structure holds less heat-soaking mass than wood, so the stove's work goes into the air, not the walls.
Hear the rain against the panels or the birds just outside the walls.
- The translucent shell takes on the colors of the landscape around it.
- Moonroof and window options for stargazing.
- A sauna that feels open and calm instead of dark and closed.
The patented Convection Curve roof circulates heat naturally from top to bottom.
- A 4-vent system distributes air evenly, with controllable exhaust to tune each session.
- The seamless shell holds the steam that wood joints slowly leak.
Unlike permanent structures, NorthUp saunas are designed to adapt to your life, whether that means repositioning, relocating, or taking it with you.
