Iki Wall Electric Sauna Heater

A slim wall-mount heater that loads up to 308 lb of stones, so you enjoy deep, long-lasting löyly without giving up bench space.

About The Iki Wall Heater

Want plush, humid steam in a tight sauna?

The Wall IKI delivers. It hugs the wall, yet its huge stone bed stores heat like a brick oven.

That means softer air, fewer hot spots, and more time relaxing instead of tending the fire. Made in Finland from stainless steel, it turns any 176 – 565 ft³ sauna into a spa-grade retreat.

Key Benefits

Ultra-slim depth – Saves floor space

Just 9–10.6 in. deep, so benches and foot traffic stay open.

Oversized stone mass – Softer steam

Up to 308 lbs of rock releases gentle, even heat that lasts long after the elements cycle off.

Hand-made stainless frame – Built for decades

304-grade Finnish stainless resists rust and warping better than painted steel boxes.

10-year stainless warranty – Peace of mind

Stone cage and frame carry a decade-long material guarantee; whole heater 2 yrs residential.

4-in. safety clearance – Easier layouts

Minimal 100 mm setback lets you embed it between benches or against tempered glass.

Optional UKU Wi-Fi control – Start from your phone

Schedule, pre-heat, and monitor temps in the app; alerts if someone leaves it running.
