We stock electric and wood-fired heaters for sauna rooms from 40 to 500+ cubic feet. The key is matching your heater’s kW output to your room size and how you actually use your sauna.
Here’s what matters: A properly sized heater heats up faster, holds temperature better, and gives you that soft löyly (steam) that makes a sauna session feel right. Too small and you’re waiting forever. Too big and it’ll cycle on/ off for too long.
Not sure what you need? Call us at 612-505-9700. Tell us your room dimensions and whether you’re building new or replacing an old heater. We’ll walk you through it – usually takes about 5 minutes to narrow down your best options.

SaunaLogic 2.0 Specs
What is the BioWater Technique Water Tank and why would I want it?
What is it? – The BWT tank is a stainless tank placed within the rocks & elements of the heater. You pour water (add essential oils for additional benefits and aroma) into the tank before turning on the heater, and as it warms up, the water evaporates into the room raising the humidity levels in the sauna room.
Why do I want it? – By raising the humidity levels in the room, you “feel” more heat at a lower temperature. When throwing water on the rocks to produce steam, it hits you gentler. This is not to be mistaken with a lesser sauna experience, but rather gives you the option for different sauna experience.
All Finnleo Sauna Heaters use Vulcanite Rock. With a high metal content, the Vulcanite Rock holds heat very well. The durable, igneous (meaning it formed from lava/magma) rock does not break apart easily under heat. It is odorless, safe, looks great, and most importantly gives a great steam.
Vulcanite Sauna Rock Notes :
*All sauna rocks eventually break apart, and need replacing (With Vulcanite rock – we are talking about years, even with heavy use and steam). If heater isn’t working how it once was or you are having troubles with the heater tripping, it is a good idea to check the rocks. If you see a lot of smaller broken pieces jammed up at the bottom, that is probably the culprit.
