A better way to sauna.

Engineered for fast heat, natural light, perfect steam, and true portability.

The NorthUp Difference

Unlike traditional saunas designed around the limitations of wood — slow to heat, dark, with inefficient heat and steam distribution, and fixed structures...

NorthUp reimagines sauna design.

Using a patented shape and modern materials, it delivers faster heat, enveloping steam, and a unique connection to the natural world beyond the sauna walls.

The entire structure is engineered to heat quickly and efficiently so you can enjoy a sauna session whenever you want.

Key Benefits

  • Reach 200+°F year-round in as little as 30 minutes while traditional saunas often take 1-2 hours
  • Use your sauna spontaneously — not just when planned

Design Details

  • The curved design minimizes wasted space, reducing interior volume for faster heat-up times.
  • Solar lift: direct sunlight can raise interior temps up to 75°F above ambient before the heater is on.
  • Low-thermal-mass construction allows for rapid temperature gain.
  • Elevated top-bench allows you to sit in the hottest part of the sauna.
  • A smaller door, placed on the short side of the sauna, helps retain rising heat.
  • Because heaters naturally draw in cool air, placing the heater near the door helps keep colder air away from bathers.

Our minimalist design replaces the dark wood box with a light-filled sauna experience that feels open, calm, and connected to the outdoors.

Key Benefits

  • Surround yourself with natural light instead of darkness
  • Enjoy views of the woods, lake, snowfall, or night sky
  • Hear the rain against the panels or birds just outside the walls
  • A more spacious and calming sauna experience

Design Details

  • Clear moonroof or window options for stargazing and wildlife viewing
  • Translucent panels that take on the colors of the surrounding landscape
  • Minimalist structure that maximizes openness, sightlines, and natural light

Airflow and geometry are carefully engineered to produce soft, even steam throughout the sauna — not hot and cold zones.

Key Benefits

  • Even heat from floor to ceiling
  • Softer, more comfortable steam
  • A consistent, high-quality sauna experience

Design Details

  • Convection Curve roof (patented) promotes natural heat circulation
  • Circular 4-vent ventilation system distributes air evenly
  • Controllable exhaust allows you to fine-tune the sauna environment
  • Exterior shell creates a vapor barrier, retaining heat and steam

Unlike permanent structures, NorthUp saunas are designed to adapt to your life, whether that means repositioning, relocating, or taking it with you.

Key Benefits

  • No expensive permanent foundation or site work required.
  • Lower install costs (no forklift or crane needed) and flexible placement
  • Lower shipping costs or local pickup options
  • Potentially avoid permitting requirements (check local codes)
  • Easily reposition for better views or seasonal use
  • Transport your sauna to a new home if needed

Design Details

  • NorthUp Core sauna kit designed for easy assembly and disassembly. Put it away for the summer.
  • NorthUp Curve and Curve XL built with durable skid for transporting and repositioning onsite.
  • NorthUp Curve Mobile sauna trailer is built onto a highway safe aluminum trailer. Perfect for a commercial sauna business or for moving to your cabin, your neighbor, or closer to the views.
