IKI Pillar 6.6 Electric Sauna Heater

The IKI Pillar 6.6 Electric Sauna Heater combines authentic Finnish sauna engineering with a sleek vertical design that maximizes stone capacity while minimizing floor space. Designed, engineered, and manufactured in Finland, the Pillar 6.6 delivers exceptional heat retention through its large stone volume and durable stainless steel construction.

With a powerful 6.6kW heating output and an impressive 264-pound stone capacity, the Pillar 6.6 creates the rich, soft löyly that Finnish sauna enthusiasts seek. Its compact footprint makes it an excellent choice for smaller sauna rooms while still providing the performance and stone capacity typically associated with much larger heaters.

The open stainless steel basket design allows maximum exposure of the stones, producing consistent radiant heat and excellent steam generation. Pair the heater with the required IKI UKU Wi-Fi control system to enjoy modern sauna control from inside the sauna or remotely through the mobile app.

Benefits of the Pillar Design

The Pillar Series is designed to maximize stone capacity while minimizing floor space. The vertical basket construction exposes a larger stone surface area, allowing water to reach more stones and create softer, richer steam throughout the sauna.

Unlike many compact heaters, the Pillar 6.6 maintains a large thermal mass. The result is longer heat retention, more stable temperatures, and a more traditional Finnish sauna experience.
