About
Steady Medium MACU combines contemporary outdoor design with practical, durable materials. The NightBlack exterior creates a confident and modern look, while the CasualGray interior adds a calm and timeless atmosphere to your bathing space. The outer shell is made from durable recycled plastic panels designed for long-term outdoor use. The surface withstands changing weather conditions, maintains its appearance and requires no surface treatment — simple cleaning is enough. This makes this tub particularly well suited for active, everyday bathing. Inside, the smooth surface feels pleasant and velvety against the skin. It resists dirt and impurities and does not peel over time, ensuring hygienic and low-maintenance use year after year. The integrated bench enhances comfort and functionality. It supports the back during bathing, simplifies entry and exit, and naturally serves as an armrest when shared. With space for 4–6 bathers, the layout supports relaxed and social moments. The external MACU wood-burning heater is crafted from high-quality marine-grade aluminum for dependable durability. Positioned outside the tub, it maximizes interior space while delivering steady heat transfer. Heating typically takes approximately 2–2.5 hours depending on outdoor conditions. An insulated safety cover is included to improve heat retention, protect the interior from UV radiation and keep debris out of the water. Standardized according to EN 17125, it adds an additional layer of safety. Wooden steps are delivered pre-assembled for secure and stable 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. The Steady hot tub is manufactured in Finland and built on 25 years of Nordic hot tub expertise developed by Kirami — part of the Harvia team since 2021. This ensures proven construction, reliable materials and long-term performance. Designed for frequent use and modern outdoor living, the Steady hot tub offers practical comfort without maintenance concerns.

Hot tub benefits
Natural recovery in warm water
