About
Steady Medium CUBE brings together clean, modern design and materials chosen for practical, everyday performance. The NightBlack exterior panels create a sleek and architectural appearance, complemented by the soft CasualGray interior that feels fresh and balanced. The durable recycled outer panels are built for changing outdoor conditions. The surface retains its appearance without staining or additional treatment — regular cleaning is sufficient. This makes the Steady hot tub an ideal choice for frequent bathers who value simplicity. Inside, the smooth and hygienic surface feels comfortable against the skin and remains easy to maintain season after season. It resists dirt and does not peel over time, supporting long-term durability and cleanliness. A thoughtfully integrated bench improves comfort and accessibility. It provides back support, makes entry easier and functions naturally as an armrest during shared bathing. The layout accommodates 4–6 people for relaxed social use. The external CUBE wood-burning heater, made from high-quality marine-grade aluminum, provides efficient and reliable heating. Positioned outside the tub, it preserves bathing space while warming the water in approximately 1.5–2 hours depending on conditions. The included insulated safety cover helps retain warmth, protects against UV exposure and keeps debris out of the water. Standardized according to EN 17125, it enhances safety. Wooden steps are delivered pre-assembled for convenient and stable access. LED lighting is available as an optional feature to elevate the overall experience. Integrated lights enhance the tub’s appearance and provide a pleasant ambient light for evening use. Manufactured in Finland and built on 25 years of Nordic hot tub expertise developed by Kirami — part of the Harvia team since 2021 — the Steady hot tub reflects trusted design and materials made for long-term outdoor enjoyment. The Steady M CUBE hot tub is ideal for those who appreciate modern aesthetics, low maintenance and a faster path to warm water.

Hot tub benefits
Natural recovery in warm water
Soaking in warm water helps muscles and joints relax by improving blood flow and easing stiffness. The gentle buoyancy reduces pressure on the body, supporting recovery after physical activity and relieving everyday tension.
