Quick Overview

100 kg of sauna stones are held in a brushed steel brazier.

All of 100 kg of sauna stones are held in a steel brazier. The secret behind this top-quality stove’s soft and relaxing heat is in full-length heating elements that heat up even the topmost stones on the stove. The heat radiates evenly and quickly in every direction. The beautifully designed brazier ensures that the eye-catching collection of natural stones is a real centre piece in the sauna.

You can give free rein to your interior design plans as Rocher can be installed in a corner or on the floor near a wall, or in the middle of the sauna sunk into the benches, using a glass or soapstone collar also suitable for underlighting.

The Rocher DE model is controlled by a Midi or Digi II controller. For Rocher DET, controller options are T1 and EC 50.


The Features

Heat from the entire stove

Due to the full-length heating elements, Rocher radiates heat evenly along its entire height. The elements are fully surrounded by the 100 kilograms of stones, essentially heating every single stone.

Brushed steel brazier

Robust steel brazier bars hold the 100 kilograms of stones in place. The hi-quality, modern design of the steel bars steadily hold the weight of the stone and can withstand extreme temperatures, ensuring the best sauna experience.

Greater stone surface

With 100 kilograms stone surface, Rocher gives an ideal soothing, soft and even steam in every direction. The impressive visual amount of stones further adds to Rocher’s unique design.

Integration opportunities

Because of its unique round shape Rocher offers exciting and flexible integration opportunities in your sauna room. It can be freestanding or sunk into a lower bench with an internal glass or soapstone collar.
