FUUSIO is the most versatile model in Thermalux’s ALU collection. This modular concept allows you to combine multiple wellness functions into a single sleek, architectural unit. From a compact sauna with ample storage to a full wellness suite with shower, changing area, relaxation zone, or even a steam cabin—FUUSIO is fully custom-designed to suit your space, style, and preferences. The exterior is finished with maintenance-free aluminum cladding in white or black, matte or glossy, or in any RAL textured finish of your choice. The hidden roof edge and minimalist lines create a modern, timeless appearance. Inside, white or black composite panels combined with thermo ayous slats provide a warm, stylish atmosphere. Infrared heaters can be seamlessly integrated without compromising the design. FUUSIO offers complete freedom in layout and function. Combine a Finnish sauna with a steam cabin, place a shower in between, add a technical room, or create an extra sleeping or work area. Compact or spacious, indoor or outdoor—anything is possible. Thanks to its modular nature and high-quality finishes, FUUSIO is the perfect solution for those who refuse to compromise on comfort, aesthetics, and functionality. FUUSIO is not a standard sauna. It is a complete concept, designed around your life.
