Description
SL-IKI wood burning sauna stove offers an unparalleled sauna experience and can also be enjoyed as a fireplace.
This outside heated sauna stove has a large amount of stones for heat storage and the ability to serve as a fireplace. The generous stone quantity ensures a long-lasting heat, even after the fire has gone out. Operating the stove from outside also helps maintain a clean sauna room.
With a safety distance of only 10cm to flammable materials from the sides of the stove, it allows flexibility in the sauna bench placement. Additionally, the IKI SL wood-burning stove is available in a plus-sized model with an upper mesh of 100 cm.
You can purchase IKI Plus Parts, including a stainless steel stove mesh and smoke connection pipe(s) here.
SUFFICIENT AMOUNT OF STONES & FLUE PACKAGES TO BE PURCHASED SEPERATELY
*The SL-IKI model has been updated in 2025. The improved version comes with a stove base as standard, and a wooden door handle for comfort and ease of use. Please note that the height of the flue connections have also changed accordingly. You can find the details in the Installation Manual under the "Downloadable Files" tab.

About IKI Kiuas
IKI Kiuas is the leading manufacturer when it comes to open structured sauna heaters. IKI was the first company to manufacture sauna heaters where the stones are visible, allowing to have water thrown not only onto the top of the heater but also onto the sides of the heater body. Their electric and wood burning heaters with stainless steel mesh frames and substantial stone capacities are hand crafted in Pieksämäki, Finland by dedicated sauna heater craftsmen that have over 40 years’ experience in welding black iron and stainless steel. The humid and soft steam characteristic of the IKI stoves is created through the large stone capacity of the electric and wood burning sauna heaters. The significant number of stones encased in a stainless-steel mesh also allows a pleasant and long-lasting steam experience with a relatively short heat up time of approximately an hour, even in the case of their larger wood burning sauna heaters.

Please note that the IKI sauna heaters are hand-made and welded, so they may have small tooling marks on the stainless-steel rim.
