Finnleo Himalaya Rock Tower Heater
The Himalaya offers the softest sauna heat experience on the market today.
The Himalaya is the most popular electric traditional sauna heater on the market today. Its soft heat and overall durability combined with its modern look create the best sauna experience that an electric sauna heater can offer.
The Himalaya Electric Sauna Heater features a rock tower design with 210 pounds of rocks and standard BWT technology (an integral water tank that emits soft steam during the sauna session). The combination of soft heat from the large rock mass and the humidity from the Water Tank is a “game changer” in the sauna industry, creating a much more pleasant sauna experience. Add a glass ring for in-bench designs and your sauna will look as beautiful as it is functional.
Words don’t do the Himalaya difference justice, once you feel it, you will know.

Biowater Technique Tanks.
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.
Vulcanite Sauna Rocks
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 :
- We use different size rocks depending on the heater.
- More rock = Softer (better) steam.
- Rock should not be jammed tightly into the heater, nor should it be too spaced out. Too tight of packing results in heater tripping issues, not tight enough results in a harsher steam. Refer to heater manual, or give us a call.
*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.
