Upgrade your Revival sauna from electric to authentic wood-burning heat. The Harvia M2 is one of the most respected wood-burning sauna stoves in the world — powerful, atmospheric, and completely independent from the electricity grid.
There is a reason wood-burning saunas have existed for centuries.
The Harvia M2 produces a heat that no electric stove can replicate. Softer, more enveloping, and more alive — the warmth from a wood fire builds gradually and fills the barrel evenly, creating a löyly experience that feels genuinely Nordic rather than just hot. Add water to the stones and the steam rises slowly, deeply, in a way that gets under the skin.
At 16.5kW, the M2 is a serious piece of equipment. It powers through even the largest Revival barrel saunas and performs exceptionally well in the cold and damp of the Irish climate. No app, no timer, no fuss — just fire, heat, and the satisfaction of a ritual done properly.
This upgrade includes everything needed for a complete installation: the Harvia M2 stove, the full chimney system with rain cover (mushroom cap), and the fireproof fibre-cement plates required for safe installation inside the barrel.
Please note: This upgrade replaces the standard Harvia M90 electric stove. It is selected at the time of ordering your sauna — it cannot be added after delivery without additional work.
