Saunaofen Harvia Unio

Gentle. Space-saving. Expressive.
The Harvia Unio is a true space-saving wonder among electric sauna heaters. With its compact corner design and surprisingly large stone surface, it ensures generous, humid infusions even in the smallest saunas – reaching deep into the lower benches.

For small spaces, big impact
With only 3.6 kW of power, the Unio is ideal for small sauna cabins with a volume of 1.5 m³ or more. Its installation flexibility is impressive: The freestanding heater is mounted in the corner to save space, blending in discreetly while still making a design statement with its tall, clean shape.

Moist infusions like in the large sauna
The generous amount of stones of up to 40 kg creates excellent heat storage and ensures long-lasting, mild steam – just as you would expect in a traditional sauna, only in a smaller format.

Simply plug in. Enjoy intensely.
The Harvia Unio is operated with an external control unit of your choice (not included). This gives you even more freedom in designing your sauna.
