The Warm Living brings you the Monolith IKI electric sauna heater — a designer open-structure heater created by dSign Vertti Kivi & Co. in partnership with IKI Kiuas. Its brushed stainless-steel mesh frame keeps the sauna stones fully visible on every side, letting löyly be thrown around the entire body of the heater, not just the top, for a richer and more even steam.
Hand-welded in Pieksämäki, Finland by craftsmen with over 40 years of experience, the Monolith IKI suits style-conscious sauna owners who want striking Finnish design paired with serious performance. It's available in three power outputs — 6.9kW, 9kW, and 13.8kW — to match saunas from cosy home cabins to larger installations.
- Open, mesh-frame construction with visible stones on all sides for full-body löyly
- Brushed stainless-steel pipe structure, durable and striking in any sauna
- Large stone mass for a humid, oxygen-rich steam experience
- Choice of no control unit (bring your own) or the IKI UKU Wi-Fi Controller
- Three power options: 6.9kW, 9kW, and 13.8kW, all 3-phase
- Handcrafted in Finland with over four decades of manufacturing expertise
Because the stones sit exposed on every face of the heater, the Monolith IKI produces steam more evenly than closed-structure heaters and is ready for bathing in around 45–60 minutes. The optional IKI UKU Wi-Fi Controller lets you start heating remotely from your phone, so your sauna is ready the moment you are, while its Finnish design credentials make it as much a statement piece as a heat source.

Sauna stones are sold separately. Heaters above 12kW are made to order in Finland once your order is confirmed and cannot be cancelled or returned after production begins, so please confirm your electrical specification with your electrician before ordering.
Installation must be carried out by a qualified electrician on a 3-phase supply. Once fitted and loaded with the correct stone quantity, the Monolith IKI heats up in roughly 45–60 minutes. If fitted with the optional UKU Wi-Fi Controller, you can start heating remotely via the companion mobile app, and the unit also supports lighting control, a timer, a door magnet, overheating protection, and a child safety lock.
We stock genuine IKI Kiuas heaters, hand-welded by craftsmen with over 40 years of experience, so you get an authentic Finnish designer sauna heater without the wait of a custom overseas order.
