A premium 2-person indoor sauna from the OKA Design range, combining the authentic heat of a traditional Finnish sauna with the advanced benefits of modern infrared therapy. Crafted from rich dark Thermo Abachi wood, it delivers a sleek, contemporary finish with exceptional durability.

Powered by a HANSCRAFT electric sauna heater with intelligent WiFi control, you can preheat and manage your sauna effortlessly from your smartphone. The integrated infrared system uses advanced nano carbon film technology to provide deep, even, and energy-efficient heat.

Inside, the sauna is designed for total relaxation, featuring a striking starry ceiling set against a black backdrop, ambient lighting to create a calming atmosphere, a targeted lumbar physiotherapy panel for enhanced back relief, and ergonomically designed backrests for maximum comfort.

Luxury Sauna Made From Premium Wood 

This combined sauna is crafted from carefully selected African Thermo Abachi timber, widely regarded as one of the finest materials for demanding sauna environments.

The wood undergoes a precise thermal modification process at temperatures between 180–215°C, without the use of any chemicals. This treatment enhances the wood’s stability and performance by removing sugars, resins, and other organic compounds that can cause internal stress, unwanted odours, and long-term degradation.

The result is a beautifully refined material that offers exceptional durability, improved resistance to moisture, and a clean, consistent finish—perfectly suited for a premium sauna experience.

The result is a high-performance material with exceptionally low moisture absorption, outstanding dimensional stability, and long-term resilience in extreme heat and humidity.

Its naturally open, porous structure helps regulate moisture within the sauna, maintaining a balanced microclimate while promoting consistent, even heat distribution throughout the space.

Free from resins, the wood remains clean and odour-free even at high temperatures, ensuring a more hygienic and comfortable sauna experience over time.

Thermo Abachi is valued for its exceptionally low thermal conductivity, meaning benches, backrests, and all contact surfaces remain comfortable to the touch—even at temperatures exceeding 90°C.

Through the thermal modification process, the wood develops a rich, uniform colour that remains stable over time, eliminating the need for additional surface treatments.

The use of solid, full-length boards with minimal joints enhances the overall structural integrity while creating a clean, seamless aesthetic—highlighting both the craftsmanship and premium finish of the interior.

OKA Design

The OKA Design collection was developed in collaboration with architect Ondřej Kamenický, a long-standing partner of HANSCRAFT in the creation of premium wellness products. This partnership has also shaped the acclaimed OKA and OKANDINAVIA collections, recognised for their refined use of materials, balanced proportions, and calm, timeless design language.

Building on this experience, the collaboration was naturally extended into the sauna category. Ondřej Kamenický designed a range of combined saunas for HANSCRAFT that seamlessly integrate traditional Finnish sauna bathing with advanced infrared technology, while maintaining the signature design language of the OKA Design series.

The result is not a compromise between two systems, but a fully unified wellness solution—where form, function, and performance work together as one cohesive concept.

Technology & Construction Solutions

The OKA Fusion Synergy 2 sauna is designed as a seamless fusion of a traditional Finnish sauna and modern infrared technology. At its core is a powerful 6 kW HANSCRAFT electric heater, delivering authentic sauna performance with fast heat-up times and consistent temperature control via an integrated touch panel.

For added convenience, an intelligent WiFi controller allows you to manage the sauna remotely through the Smart Life mobile app, giving you precise control over temperature and operating settings—whenever it suits you.

The infrared section is equipped with a modern heating system using nano carbon foil, delivering smooth, even, and energy-efficient warmth throughout the cabin. Operating within the IR-C spectrum, the system combines multiple heating panels with a dedicated 300 W lumbar physiotherapy panel for targeted relief and enhanced comfort.

With a total output of 2,190 W, the infrared system provides deep, penetrating heat without overheating the surrounding air—creating a more comfortable, controlled, and effective wellness experience.

The construction is enhanced by a rear wall clad in slim black slate stone, adding both thermal mass for improved heat retention and a striking visual focal point. The lower and rear sections are finished with Black Sauna Wax, increasing resistance to moisture and everyday wear while creating a cohesive, deep-toned interior aesthetic.

An integrated floor is also included, purpose-built for sauna environments to ensure long-term durability, practicality, and easy maintenance.

Red Light Physio Zone

Experience targeted back care as part of your sauna routine. The Red Light Physio Zone combines deep infrared heat with 660 nm red light therapy to support muscle relaxation, ease tension, and promote natural recovery.

An ergonomic Softpad allows you to lean back comfortably against the heat source, with adjustable intensity to suit your needs at any moment. The result is focused back relief and a deeper, more personalised relaxation experience—without the need for complicated controls.
