It is equipped with a 6 kW HANSCRAFT electric heater with an intelligent WiFi controller and a modern infrared heating system with nano carbon foil. The sauna features a starry ceiling with a black base, ambient lighting, a lumbar physiotherapy panel, and a comfortable backrest and a complete set of HANSCRAFT sauna accessories.
Dimensions: 210 × 160 × 208 cm.
LUXURY SAUNA MADE FROM PREMIUM WOOD
Selected African timber Thermo Abachi was used in the manufacture of this combined sauna. This material is considered one of the most suitable for demanding sauna environments. The wood undergoes controlled thermal modification at temperatures of approximately 180–215 °C, without the use of any chemical substances. During this process, sugars, resins, and organic components that are typically responsible for internal stress, odors, and biological instability are broken down.
The result is a material with significantly reduced moisture absorption, high dimensional stability, and long-term resistance to extreme temperatures and humidity. Thanks to its open, porous structure, the wood naturally regulates moisture in the space, supports a stable microclimate, and contributes to even heat distribution throughout the sauna. The absence of resins ensures that the wood does not release odors even at high temperatures and remains hygienically clean.
Thermo Abachi is characterized by extremely low thermal conductivity, which means that benches, backrests, and all contact surfaces remain pleasant to the touch even at temperatures exceeding 90 °C. In its thermo-modified form, the wood gains a deep, homogeneous color tone that is stable over time and requires no additional surface treatment. The use of solid boards in continuous lengths without joints further increases structural strength and emphasizes both the technical and visual quality of the entire interior.
OKA DESIGN – COOPERATION WITH CZECH ARCHITECT AND DESIGNER ING. ARCH. MGA. ONDŘEJ KAMENICKÝ
The OKA Design collection was created in collaboration with Czech Architect and Designer Ing. arch. MgA. Ondřej Kamenický, with whom HANSCRAFT has long cooperated on the development of premium wellness products. This partnership is behind the popular OKA and OKANDINAVIA ranges, where a strong sense for materials, proportions and calm, timeless design has proven its value.
Based on these experiences, the collaboration was also extended to the sauna category. For HANSCRAFT, Ondřej Kamenický designed combined saunas that naturally integrate Finnish sauna bathing with infrared technology, while maintaining a consistent design language of the OKA Design range. The result is a sauna that does not feel like a compromise between two systems, but as one coherent wellness unit.
TECHNOLOGY AND CONSTRUCTION SOLUTIONS
The OKA Fusion Synergy 3 sauna is designed as a combination of a classic Finnish sauna and a modern infrared sauna. Finnish sauna operation is provided by 6 kW HANSCRAFT electric heaters, integrated into a heating system with a touch control panel. An intelligent WiFi controller allows convenient remote operation via the Smart Life mobile application and precise adjustment of operating parameters.
The infrared section features a modern infrared heating system with nano carbon foil, ensuring even and energy-efficient heating of the space. The system uses infrared radiation in the IR-C spectrum and includes a combination of multiple heating panels and a targeted lumbar physiotherapy panel with an output of 300 W. The total output of the infrared system is 3,175 W, enabling deep, targeted heating without overheating the air.
The construction is complemented by rear wall cladding made of thin black slate stone, which contributes to heat accumulation and serves as a strong aesthetic element. The lower and rear parts of the sauna are treated with Black Sauna Wax, increasing resistance to moisture and mechanical wear while unifying the dark interior appearance. The construction solution also includes an integrated floor designed for long-term operation and easy maintenance.
Red Light Physio Zone
Targeted back care directly during your sauna session. Red Light Physio Zone combines deep infrared heat with red light therapy (660 nm) to support muscle relaxation and natural regeneration.
The ergonomic Softpad allows you to comfortably lean directly against the heat source and adjust the intensity according to your current needs. The result is effective back relief and deeper relaxation without complicated controls.
