About

With space for 6–8 bathers, it easily accommodates extended families and groups of friends without compromising safety or comfort. The integrated family bench enhances both usability and security. It simplifies entry and exit, provides stable seating for children and supports relaxed back and arm positioning while bathing. The bench also serves as a cooling seat, making transitions in and out of warm water easier. The exterior is finished with Finnish spruce panels stained in deep CoalBlack, offering a natural yet refined look that blends beautifully into garden and terrace settings. The wood cladding maintains its attractive appearance over time, creating a timeless outdoor presence. Inside, the LightGray liner has a velvety smooth, delicately dotted surface that feels comfortable and hygienic. Its soft grey tone remains elegant season after season. The black CUBE wood-burning heater is crafted from high-quality marine-grade aluminum and positioned outside the tub to maximize bathing space. Its efficient performance heats even large volumes of water in 2-3 hours depending on conditions. An insulated safety cover is included to retain heat, protect the interior from UV exposure and keep debris out of the water. Standardized according to EN 17125, it enhances safety — particularly important for family use. Wooden steps are delivered pre-assembled for secure access. With optional LED lighting, the bathing experience becomes more atmospheric. Factory-installed lights emphasize the tub’s colors and add a gentle glow for relaxing moments after dark.
