Sauna Bench Height thermal image

Bathers ABOVE The Cold Zone

Hot air rises, and heat forms in layers of air. There is no one single temperature in a sauna. Because heat layers, there are different temperatures at different heights. Most saunas are too short, with benches too low, to get your body into the hot zone, where you are EVENLY heated from head to toe. Check out this thermal image, showing 8 degrees celsius in the lower part of a winter sauna

Feet Above the Rocks

Foot bench is above the rocks, getting you into the heat pocket. This creates a better, more comfortable sweat. As well as a better heating of the entire body. No more cold feet in the sauna, putting your body out of equilibrium. This is only possible in saunas at least 8.5 feet high. It is what the Finns call ‘the first law of lóyly’, and most North American saunas are made with ceilings too low to achieve this.

Finnish Ventiliation

Fresh Air to Breathe

Ever sat in a Sauna counting the timer? Waiting for a breath of fresh air? It is because that sauna had no fresh air. Finns do not build sauna this way. Most saunas either have poor ventilation or no ventilation (enter the stuffy gym sauna). We build our saunas to have a fresh air source coming in, while exhausting old CO2-ridden air out. This is crucial. Saunas are healthy, and starving your body and brain of oxygen is not. Never count the clock again or feel like you are suffocating.

Sauna air volume

Finnish design

Enough Space

Our 8'x8'x9' minimum size ensures there is quality air, and comfortable heat for bathers. Every inch less, even for one bather, has an impact on the sauna experience. We want more air volume for the bathers to breathe in. And we want a further distance from the heater; To feel the convective heat (like a hot air bath), and not the harsh radiant heat from the heater

TL;DR Proper Finnish Design

  • Because hot air rises, bathers entire bodies need to be higher in the sauna room for even heating of the body
  • Feet above the stove's stones, what the Finns call the "first law of lóyly". Ensures the body is heated head to toe, no more cool feet.
  • Fresh air, with a ventilation system to bring fresh air into the sauna, and exhaust old air out. Feel the heat, not the feeling of suffocation
  • A big enough room (8ft x 8ft x 9ft) is crucial to the design. Allowing enough breathing air space, and comfortable convective heat away from the heater.
