Juup Iivari

Artesan sauna stove


Juup Iivari is the next generation of Juup Original, born of the real need of our customers. Juup Iivari is very similar in structure to its predecessor, but it is better suited for smaller sauna rooms. Like its predecessor, it offers very versatile löylys.

The stone cradle of Juup Iivari fits approx. 45 kg of sauna stones, depending on the size and material of the stones.

Thanks to its robust and durable construction, the stove carries a 10-year warranty in home use.

Juup Iivari can be ordered with either rear or vertical smoke flue. The walnut handles shown in the pictures are available at an additional cost.

Make sure to check out Iivari Punos, which is fitted with an even larger stone cradle!

Versatile löylys

In Juup stoves, the sauna stones are directly above the fireplace in a “stone bowl”.

This allows the stones to heat up quickly and every drop of water to evaporate into the sauna. The water that does not immediately evaporate on contact with the hot stones drains down to the bottom of the bowl and gradually evaporates. This results in soft, humid and long-lasting löylys.

By adjusting the temperature of the stove and the amount of water, you can create exactly the kind of löylys you like. Sharp löylys are created when you throw small amounts of water onto a hot stove several times. But if you like soft and humid löylys, pour more water into a stove at lower temperature. This creates a steam bath-like löyly.

The heater body and fireplace are constructed of 3 mm carbon steel and the fireplace has only one weld seam. This allows the stove to last from one generation to the next. The original stoves, built by Gösta Juup in the 1950s, are still in use.

Thanks to its solid and durable construction, we grant the stove a 10-year warranty in home use.
