The Rakka Mondex sauna heater combines Finnish sauna tradition, the raw beauty of Lapland, and modern technology to deliver an authentic and deeply relaxing sauna experience. With its massive stone capacity and unique design inspired by northern Finland’s rocky landscapes, Rakka offers soft steam, long-lasting heat, and a connection to the roots of sauna culture.

Design and Stone Capacity
At the heart of Rakka is its stone-heavy design. The 10.5 kW model holds up to 200 kg of sauna stones, ensuring powerful heat retention and a steady release of moisture. This large stone capacity allows water to be poured generously, producing soft, moist steam that mimics the gentle warmth of a traditional wood-burning sauna.
Unlike conventional heaters that use metal nets, Rakka’s patented structure highlights the raw stones themselves. Steam rises freely through the stone mass, creating a natural, immersive atmosphere that enhances every sauna session.
Inspired by Lapland’s Nature and Traditions
The name “Rakka” comes from Lapland and refers to rocky boulder fields found across northern Finland. These rugged landscapes inspired the heater’s design and symbolize endurance, authenticity, and connection to nature.
Rakka also pays homage to ancient shamanic sauna traditions of Finland, where sauna rituals were deeply tied to relaxation, healing, and spirituality. By drawing on Lapland’s geological formations and cultural heritage, the Rakka Mondex sauna heater bridges the wilderness of the north with modern comfort.

Performance and Controls
The Rakka sauna heater is available in several power ratings to suit both small and large saunas. Users can choose between:
- E2 electronic control with precise one-degree adjustments and optional Wi-Fi for remote operation.
- Mechanical control panel for a more traditional, hands-on approach.
The control unit can be installed in the sauna, dressing room, or another convenient location. A wall-mounted sensor ensures accurate temperature readings, making it easy to achieve the perfect sauna environment.
Gentle, Luxurious Steam
Thanks to its enormous stone mass, the Rakka Mondex delivers gentle, luxurious löyly—the soft steam that defines the Finnish sauna experience. The heat feels soothing, never harsh, and allows bathers to fully relax, unwind, and connect with the calming warmth of Lapland’s natural stones.
