Description
A slim electric sauna heater for small saunas
The CLIFF 6 kW is built for compact saunas. Its narrow stainless-steel body carries remarkably small safety distances, so it slots into tight rooms from 177 to 318 cu ft.
Big stone capacity, soft heat
A generous 165 lb stone capacity — unusual for a heater this slim — with direct stone-to-element contact gives you a longer, milder heat and rich löyly.
Wi-Fi control with HUUM UKU
Pair it with a HUUM UKU or UKU Wi-Fi control to preheat from your phone. Stainless steel, designed and made in Estonia.
Required UKU control and sauna stones (5 boxes) sold separately.

Frequently asked questions
What size sauna does the CLIFF 6 heat?
Small home saunas from 177 to 318 cubic feet.
Why so many stones for a small heater?
Its 165 lb capacity stores more heat, so a small sauna holds a steadier, softer temperature and better steam.
What else do I need?
A HUUM UKU control (Wi-Fi optional) and 5 boxes of sauna stones, both sold separately.
