Mondex Motti Wood Sauna Stoves

Mondex Motti is the sturdier cousin of Mondex Klapi and thus meant for medium to larger saunas. It has a modern, angular design and a wooden handle for safe grip.

Like Klapi, Mondex Motti has a large stone capacity (132 lbs) for endless löyly (steam) even after the fire has died, it heats quickly, and is a low-emission sauna heater.

They also share the same efficiency score (71%), which translates to you needing less wood for heating, and fireplace ceiling thickness (8 mm) for longer lifespan.

For the truest sauna bathers, Mondex offers their Motti models also with built-in water tanks (coming soon).

The model name Motti is Finnish and loaded with meaning: it’s a cubic meter of stacked firewood.
