The Holl’s Onyxia Cube embodies the essence of shared well-being: an elegant and spacious space, designed to accommodate up to 4 people. Combining modern and premium design, responsible materials and intense heat, it offers an immersive experience to relax and revitalize body and mind. Create a true haven of peace at home.
Discover the power of steam, a natural ally for relaxation and regeneration. The Onyxia Cube, with its innovative design, transforms every session into a true wellness ritual. Enjoy intense and even heat, perfect for relaxing muscles, eliminating toxins, and revitalizing your mind. Designed to integrate seamlessly into any environment, this sauna combines tradition and modernity for unparalleled pleasure.
Thermowood®, used in the design of the Onyxia Cube, embodies durability and elegance. Transformed through an eco-friendly, chemical-free process, it offers exceptional resistance to fungi and insects while being 100% recyclable. It’s dimensional stability reduces variations caused by humidity, ensuring optimal use in all seasons. Let it age naturally to reveal an elegant silver hue, or enjoy it as is, with its rich and warm colour.
Host up to 4 people in a setting of comfort and design. With its premium Thermowood paneling, both durable and aesthetic, the Onyxia Cube provides a compact yet generous space, ideal for sharing relaxing moments with family or friends. Featuring smoked black tempered glass, this cabin guarantees total privacy while offering a soothing view of the outdoors. Manufactured in Europe, it is built to last.
The Onyxia Cube offers simple yet elegant customization options to suit your aesthetic preferences. Choose the front panel according to your taste: glazed for an open and bright view, or classic for a more discreet appearance. At the back, opt for a semi-circular glass panel for an extra touch of transparency, or the classic version for more intimacy. These choices allow you to adapt the sauna to your environment while maintaining its modern and harmonious design.
Equipped with integrated white LED strips behind the seat backs for a relaxing atmosphere, the Onyxia Cube is compatible with stoves from 4.5kW (no stove is included) for heat tailored to your preferences.
