Expert help that stays with you

Small details become expensive problems once installation begins. We ask the questions early, so a mismatched part, an overlooked requirement or an installation issue gets caught while it is still easy to fix.

Our job does not end when your order ships. We stay available through installation and beyond. If something needs attention, we stay involved, work the problem, and help see it through.

We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

Sauna and heater customers also receive free shipping on sauna accessories for life.

ProSaunas Sauna Thermometer and Hygrometer | Pine or Cedar

Is the sauna running cool, or is the gauge simply hanging lower than the heater’s sensor? This ProSaunas board puts two analog dials side by side: a thermometer that reads 40 to 240°F and a hygrometer that reads humidity from 0 to 100 percent, behind glass made to resist cracking and leaks. The board is 9.8 in wide and 4.9 in tall, in knotless Finnish pine or knotless Canadian red cedar, with screws and calibration tools in the box.

Why the wall and the heater disagree

Heater controls measure near the ceiling, where the air is hottest. EOS spells it out in its heater manuals: the temperature drops between the ceiling and the foot area, the set values are taken at the ceiling, and thermometers below the ceiling register lower. So a wall gauge at bench height reading cooler than your control is normal. Hang this one where you want to know the temperature, and read it as the heat at that height.

Two dials

The thermometer’s main scale runs from 40 to 240°F, with a Celsius scale on an inner ring. The hygrometer reads relative humidity from 0 to 100 percent, so you can watch what a ladle of water on the stones does to the room. Both sit behind glass in one wooden board only 1.2 in deep, which keeps it close to the wall.

Pine or cedar

The pine board is knotless Finnish pine and weighs 0.9 lb. The cedar board is knotless Canadian red cedar, darker in tone and 0.7 lb. The dials are the same in both.

In the box
