Sizing

What size heater does my sauna need?

Enter the room's inside dimensions. We show every heater whose own manufacturer table covers a room that size — each one with the range it publishes, and the voltage it publishes it at.

Uninsulated means glass, tile, brick or concrete — anything that soaks up heat instead of holding it in. HUUM's manual adds 3.3 ft³ of room volume for every 1 ft² of it.

Think you found a better deal?

Let's chat. We'll pull out all the stops to make sure you're not leaving money on the table — backed by a manufacturer warranty and industry-leading support to make sure you have the best possible customer experience. Talk to us before you decide.
