Space-efficient design. True Finnish sauna experience.

The IKI Wall Short Electric Sauna Heater is a compact, wall-mounted solution designed to deliver consistent heat and rich steam in saunas sized 177–353 ft³. With a 6.9 kW output, it is well-suited for smaller sauna spaces where efficient use of layout matters.

Its reduced height and slim 10.6-inch depth make it an excellent choice for maximizing usable space, while allowing greater flexibility in sauna design. The wall-mounted structure keeps the footprint minimal without compromising functionality. The heater comes with a UKU black glass remote control unit, offering a seamless combination of modern control and clean design.

Constructed from 100% stainless steel, the heater features a durable mesh frame that holds 176 lb of stones. These stones heat in approximately one hour and retain warmth over extended sessions, supporting a balanced, humid sauna environment—even at lower bench levels.

Designed for those who value authentic Finnish sauna, the IKI Wall Short produces the kind of soft, enveloping heat and abundant löyly that defines the traditional experience.
