Description
The Mini-IKI is the smallest wood-burning stove in the IKI range, an extremely powerful heater for compact saunas of 5–12 m³. Despite its size it carries 120 kg of stones, so the steam stays soft and comfortable even on the lower benches, and the rotation fire pipe that continues from the furnace heats the stone mass quickly. The draught is regulated from the knob in the glass hatch, and the model was updated in 2025 to include a stove base as standard and a wooden door handle, with revised flue connection heights shown in the installation manual. Like all IKI wood-burning stoves it is made to order in Finland and cannot be cancelled or returned once confirmed. Sauna stones and the flue kit are sold separately, as are IKI Plus parts such as the stainless steel stove mesh and smoke connection pipes.

Installation
The chimney connection is made at the rear with the 90-degree smoke pipe, or upwards using the separately sold Plus parts; the smoke pipe has an outer diameter of 115 mm and its centre sits 130 mm from the rear rim. IKI recommends connection to a brick, ceramic or air-cooled chimney, with each firebox served by its own flue. The 2025 model stands on the supplied stove base and its flue connection heights have changed accordingly; the connection heights and safety clearances are given in the installation manual in the Downloads tab, which must be followed together with local building regulations.
Sauna stones
Sauna stones are not included and must be purchased separately. IKI recommends peridotite, olivine or olivine-dolerite stones under 100 mm in diameter, laid loosely one at a time so the stones cover the furnace while air can still flow between them; in professional use Kerkes ceramic stones are recommended on the surfaces that touch the heart of the stove. The condition of the stones should be checked yearly and broken stones replaced.
Brand
IKI Kiuas is a Finnish specialist in open, large-stone-mass sauna heaters, hand-crafted in Pieksämäki by welders with decades of experience in stainless steel and black iron. Each heater is welded by hand and may show small tooling marks on the stainless steel rim.
Warranty
IKI Kiuas grants a two-year warranty for domestic use (one year for spa and other public saunas); the full terms are set out in the installation manual in the Downloads tab.
