Discover the Perfect Fusion of Style, Power and Finnish Craftsmanship
Bring the timeless tradition of sauna into your home with the Mondex Tahko Sauna Heater - a beautifully engineered floor-standing heater that delivers outstanding performance and refined Nordic design. Made in Finland using high-quality materials, the Tahko is built to provide a rich, even steam experience, while offering full flexibility in both appearance and function.
Available in three power options - 6.6kW, 9kW, and 10.5kW - and finished in either sleek Stainless Steel or modern Mondex Black, this heater is a versatile centrepiece for any wellness space.
Key Features
- The floor stove with apertures on all sides gives heat across the entire heat surface.
- Thanks to the external control unit (Tahko E2/E2 WiFi), the stove is easy to embed in the bench structure and requires no additional space for the controls.
- The Tahko stove stores enough thermal energy to dry out the sauna after use.
- Additional mounting flange and a 30 cm elevation component are available for flush mounting.
- For E2/E2 WiFi models, the controller cable length is 10 m, and the temperature sensor length is 4 m.
Built for Authentic Sauna Heat
With its impressive 80-140kg stone capacity, the Mondex Tahko delivers an authentic sauna experience characterised by deep, consistent warmth and full-bodied steam. The large stone volume stores and radiates heat gradually, allowing you to enjoy a traditional Finnish löyly that's soft, rich, and long-lasting.
Unlike wall-mounted heaters, the Tahko's floor installation allows for even heat distribution and better air flow throughout the sauna room. The result is a stable temperature, efficient performance, and that distinctive cloud of relaxing steam that true sauna enthusiasts love.
Choose the Power That Suits Your Sauna Space
The Tahko range includes three power ratings, giving you the flexibility to match your heater to the size of your sauna:
-
6.6kW - Ideal for compact home saunas (6-9 m³)
-
9kW - Perfect for mid-sized rooms (8-15 m³)
-
10.5kW - Designed for larger saunas (12-22 m³)
Whether you're creating a cosy personal space or a social sauna for guests, there's a Tahko model to meet your heating needs with efficiency and reliability.
Flexible Control Options to Suit Every Lifestyle
Tailor your sauna experience with a choice of three control systems:
-
Manual Controls - Traditional and straightforward, with robust dials for heat and timer settings.
-
E2 Digital Display - A clean, modern interface mounted on the wall for easy temperature and timer adjustments.
-
E2 WiFi Control - Full smart connectivity, allowing you to control and schedule sauna sessions remotely via your smartphone or tablet.
All versions are designed with safety and convenience in mind, ensuring every sauna session is easy to manage - whether you're relaxing solo or entertaining guests.
Sleek Aesthetics for Modern and Classic Spaces
The Mondex Tahko doesn't just perform beautifully - it looks stunning too. With two elegant finishes to choose from, Stainless Steel or Mondex Black, this heater complements a wide variety of sauna styles. Its compact footprint and minimalist silhouette make it a great fit for modern interiors, traditional wooden cabins, or luxury spa environments.
Add an optional wooden safety railing for extra protection and peace of mind, especially in family or commercial settings.
Built to Last - Finnish Engineering at Its Finest
Crafted with care in Finland, the Tahko is designed for durability and long-term use. Its outer casing is resistant to high heat and corrosion, while the heating elements are fully replaceable, ensuring the heater remains dependable for years to come.
Whether you're a seasoned sauna user or a newcomer to wellness living, you can trust in the quality and performance of a heater backed by decades of Finnish design expertise.
Ideal for Homes, Studios, and Spas
The Mondex Tahko is the perfect choice for anyone serious about creating a proper sauna experience. Whether you're upgrading your home setup, kitting out a garden sauna, or fitting a wellness studio, the Tahko brings authentic heat, beautiful design, and flexible features that cater to all lifestyles.
