IKI CORNER 9 kW
The IKI Corner 9 kW electric sauna heater is a smart solution for those looking to save space without compromising performance. Its corner-fitting design allows it to nestle neatly into the sauna’s corner, freeing up room and enabling more creative and functional bench layouts—perfect for compact or modern sauna interiors.
The front of the heater features IKI’s signature stainless steel mesh for a sleek appearance and optimal heat distribution, while the back—facing the corner—is made from solid stainless steel to retain heat longer, ensuring extended warmth from the sauna stones.
What sets the IKI Corner heater apart is its combination of compact design, powerful heating, and elegant aesthetics. Despite its size, it can rapidly heat up 308 lbs of stones, delivering an exceptional sauna experience with rich, enveloping steam—known in Finland as löyly.
Thanks to its high stone capacity, the heater produces a softer, more humid heat favored by many modern sauna users. For a traditional intense experience, pour water directly on top. For a gentler, steamier löyly, pour water along the sides.
Certified Safe and Built to Last
Handcrafted in Finland, IKI Corner heaters are made from premium stainless steel and high-quality materials, blending traditional craftsmanship with modern functionality. They are UL 875 certified to meet rigorous U.S. safety standards.
Each heater includes a 13.8” x 13.8” ceiling heat shield for safe installation. To integrate the heater into your sauna benches, we recommend using IKI’s stainless steel embedding flange for a clean, professional finish.
Control Unit Options
Built-in Control Unit
This heater model features a control unit integrated directly into the lower frame of the heater. It includes a 1-hour operating timer and an 8-hour delayed start function. Temperature is adjusted using the thermostat knob, located beside the timer knob. For further details, click here.
Wi-Fi Control Unit
This version comes with the UKU Wi-Fi Remote Control Unit in sleek black glass. It allows you to operate the sauna either through the control panel or remotely via the IKI mobile app—just ensure the unit is connected to a Wi-Fi network. The elegant control panel can be wall-mounted outside the sauna or surface-mounted using a separate mounting frame (not included in the standard UKU control unit package).

Refunds and Returns
If you need to exchange your product, you may do so. You, as the customer, are responsible for any shipping costs throughout any returns and exchange processes.
Not all orders are available for return once they have shipped. We order our products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product.
Due to drastically increasing LTL/freight shipping costs, any outright returns will incur 25% cancellation fee + return shipping costs. If you are replacing the product with something else, we may be able to help you cover some of the costs depending on the product.
Shipping Times
We promise to do our best to get your order to you as soon as possible. We provide estimated shipping times on the product pages based upon what our suppliers and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, the steel mills behind on making metal, the manufacturers delayed because of the mills, the overwhelmingly demand on shipping, factory/warehouse and dock workers and so on).
Order delays have proven to be unavoidable and outside of Sauna Heater Supply's control. While this might be frustrating, we ask you to please be patient and understanding with us in these tough times. We thank you for your business and appreciate your patience.
Warranty
Warranties vary depending upon the manufacturer - see individual product pages for details. Warranty damages occur over time and from use. If an item was damaged upon arrival, and not reported within 30 days, that is not a warranty claim.
