Misa Kiviset Wood Sauna Stove

This stony option from Misa is made in Finland, holds 441 lbs of sauna rocks, and produces abundant löyly (steam) even after the fire has died.

Despite huge rock mass, Finnish users praise Misa Kiviset for heating up surprisingly quickly and efficiently, from 50 minutes to an hour. After that, you get plentiful steam for the entire evening.

Efficient heating is enhanced by secondary combustion air that the heater receives through the hole in the soot cleanout plug at the top front.

Pouring water on top gives you the feistiest löyly, while the sides produce softer steam.

The frame is made of stainless steel and features a honeycomb design.
