The king of soapstone stoves

Read more »


The Mondex Hiisi is the majestic king of sauna stoves, combining rough-hewn Finnish soapstone, stylish black granite and advanced technology. The award-winning soapstone stove warms up across its entire surface, delivering humid and oxygen-rich heat time and time again.

The soapstone stove is a wall-mounted floor stove. Because it requires no rear safety distance, it can be installed right to a panel wall if required, saving more space for the benches.

The external control unit can be installed in the sauna, in the changing room or even into a light switch socket. Smart control electronics heat up the sauna efficiently and save energy. The control unit adapts to your sauna on the first use and learns to maintain temperature in the optimal way. The small, low-profile temperature sensor measures the temperature on the bench wall, ensuring just the right temperature every time you step in to enjoy the incredible heat of your sauna.
