SAUNA FROM SELECTED THERMO ABACHI WOOD
Selected African timber Thermo Abachi is used in the construction of Pure Essential saunas. This material is widely recognized as 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 removed.
The result is a material with reduced moisture absorption, high dimensional stability, and reliable resistance to long-term exposure to heat and humidity. Thanks to its open, porous structure, the wood naturally helps regulate moisture inside the sauna and supports a stable, comfortable climate during use. The absence of resins ensures a clean and neutral sauna environment even at high temperatures.
Thermo Abachi is known for its low thermal conductivity, meaning that benches, backrests, and all contact surfaces remain comfortable to the touch even at temperatures exceeding 90 °C. The thermo-modified process also gives the wood a warm, natural color tone that remains stable over time without the need for additional surface treatment. The use of solid boards enhances durability and contributes to the overall clean and functional design of the sauna interior.
OKA Design – collaboration with architect Ondřej Kamenický
The OKA Design collection was created in collaboration with architect Ondřej Kamenický, with whom HANSCRAFT has long cooperated on the development of premium wellness products, particularly hot tubs. This partnership has shaped the successful OKA and OKANDINAVIA product lines, recognized for their refined work with materials, balanced proportions and calm, timeless design.
Building on this experience, the collaboration was extended into the sauna category. Ondřej Kamenický designed saunas for HANSCRAFT that naturally follow the OKA Design language and place the same emphasis on material quality, technical clarity and interior harmony. The result is a Finnish sauna that feels less like a standalone product and more like an integral part of a complete wellness concept.
Interior, atmosphere and design
The interior is designed with ergonomics and comfort for up to four people in mind. A double bench made from dark Thermo Abachi is complemented by a comfortable backrest, allowing a relaxed seating position even during longer sauna sessions. The low thermal conductivity of the wood ensures pleasant contact even at high operating temperatures.
A carefully designed ambient lighting system positioned under the benches, near the footrests and on the rear wall enhances the atmosphere of calm without creating visual disturbance. A dominant interior feature is the starry ceiling with a black base, creating a visually serene and focused environment. The space is enclosed by 6 mm tempered dark grey glass with black handles and hinges, combining safety, functionality and modern design.
Technology and construction
The OKA Pure Essential 2 sauna is designed with a strong focus on long-term stability, precise control and reliable operation in demanding sauna conditions. Heating is provided by a 4.5 kW HANSCRAFT electric heater, integrated into a complete heating system with a touch control panel. The system enables fast heat-up and precise temperature regulation. An intelligent WiFi controller allows convenient remote operation via the Smart Life mobile application and easy adaptation to individual user preferences.
The construction is complemented by a rear wall clad in thin black slate stone, contributing to heat accumulation while also serving as a strong visual element. The lower parts of the sauna are treated with Black Sauna Wax, increasing resistance to moisture and mechanical wear while unifying the dark appearance of the interior. The entire solution is designed to maintain technical reliability, dimensional stability and functional performance even during long-term use. An integrated floor is also part of the construction, designed specifically for sauna environments and easy maintenance.
