Quick overview

Our IKI Review

IKI is the kind of brand people graduate to after learning what actually makes a sauna feel good. Serious Finnish heat, serious price, and still not the easiest brand to source outside Europe and select North American dealers.

Price tier
Premium
What it costs$2,278 to $4,500 USD

IKI names Sauna Revival its official US retail partner, and that shop stocks the whole line at published prices. Electric heaters run $2,278 to $2,478: the classic Pillar 6.6 kW is $2,278, the Pillar 9 kW is $2,378, and the Wall and Corner 9 kW models top out at $2,478, each with a built-in control (the WiFi UKU control versions are what push the from pricing higher). Wood stoves start at $3,100 for the IKI Mini, $3,440 for the IKI Original, and $4,500 for the big-stone IKI Löyly. US-market IKI electric heaters are UL 875 certified, which matters for permits and insurance. Ask whether your quote includes the stone load; an IKI pillar swallows well over 100 kg of stone and it is often a separate line item. Sauna Supply Co and Superior Saunas also carry IKI if you want to comparison shop, and Sauna Revival flagged a heater shipping pause from mid June to mid July 2026, so confirm lead time before you order.

Why Consider IKI?

IKI is one of the most respected Finnish heater makers in enthusiast circles. The brand is best known for tall steel mesh pillar heaters that stack stones vertically for softer, longer steam and a more forgiving heat profile than many compact electric heaters. Founded in the late 1980s in Finland by Jouni Kerrman (verified via ikisaunas.com).

Methodology

Brand verdicts are based on buyer fit, heater ecosystem, support path, price pressure, and the risks that tend to show up after delivery. A strong reply from a manufacturer can improve factual clarity, but it does not improve placement.

If support coverage, warranty language, or dealer access are thin, we would rather say that plainly than hide it behind marketing copy.
