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 similar to its predecessor but suits better for smaller sauna rooms (9–18m³). Like its predecessor, it offers very versatile löylys.

In Juup Iivari’s stone compartment, approximately 45–55 kg of stones can fit, 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.

In Iivari stoves, there is a large glass door as standard. 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!

Delivery time for stoves varies from 2 to 4 weeks depending on order quantities. The delivery time can be inquired in advance by e-mail myynti@juup.fi or by phone on 040 737 1571.


Juup Iivari is the next generation of Juup Original, born of the real need of our customers. As its predecessor, Juup Iivari offers versatile löylys, but is designed for smaller sauna rooms. The stove is robust, and will serve for decades.

Versatile löylys

We wanted to develop a stove that provides the best and most versatile steam. We have taken the long, moist, and soft steam of a smoke sauna as our model.

The ‘secret’ of the steam in smoke saunas lies in the way the stones are heated. The stones at the bottom get incredibly hot, while the surface stones remain relatively lukewarm throughout the sauna session. When water is poured onto the stones, it doesn’t evaporate immediately from the surface stones, but flows down to the bottom of the stone compartment where evaporation occurs. As this steam travels through the cooler stones, a condensation process begins which softens and moistens the steam.

In Juup stoves, the stones are directly above the firebox in a “stone bowl.” This allows the stones to heat up quickly and every drop of water to evaporate into the sauna. The stones at the bottom heat up first and remain hot throughout the sauna session, just like in a smoke sauna.

The stones on the surface of the stone bowl heat up slowly, allowing for the creation of different types of steam during the sauna session. The water that doesn’t evaporate upon contact with the hot stones flows down to the bottom of the bowl and evaporates gradually. This results in soft, moist and long-lasting löyly.

By adjusting the stove’s temperature and the amount of water, you can create exactly the kind of steam that you like. Crisp steam is created when you throw small amounts of water onto the hot stones on the edges frequently. If you prefer soft and moist steam, you can pour a larger amount of water on the lukewarm stones. 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.
