What are Hekla Cube Saunas
The Hekla cube sauna is a modern, space-efficient outdoor sauna designed to maximize interior volume without increasing its external footprint.
Unlike traditional barrel models, the square structure provides vertical walls and a flat ceiling, creating more usable headroom and versatile seating layouts.
The Hekla Cube is crafted from premium Thermowood (thermally modified Nordic Spruce), which offers superior durability and natural resistance to the elements.
Featuring striking panoramic glass panels, these saunas blend contemporary Scandinavian aesthetics with high-performance wellness. Whether you choose wood-burning or electric heating, the cube design ensures even heat distribution, making it the perfect luxury retreat for any garden.
The cube design offers maximum headroom and superior air circulation, ensuring consistent heat throughout the cabin. Its space-efficient shape fits seamlessly into modern gardens, while extra-wide benches and panoramic glass provide a spacious, luxury lounging experience without a larger footprint.
Benefits of a Cube Sauna
Heats Quickly & Efficiently
With less unused space (imagine a circle inside a square), the cube design lets the heater do its job faster and more efficiently. In a square sauna, the heat gets trapped at the ceiling. In a cube sauna, the heat is pushed back down the curved sides and into the sauna as new heat rises from the heater.
Requires No Maintenance
Barrel saunas naturally shed water and, due to their structural integrity, can handle a substantial snow load. The polymer support cradles let you put the barrel on any flat surface, and the Thermowood is naturally resistant to water and insects.
Saves Energy
Because there is less unused airspace to heat, less energy is required to heat the room. The thick staves are excellent insulators, and the exterior of the sauna will remain cool to the touch.
Accommodates Temperature Flux
The ball-and-socket assembly of a cube sauna lets the wood expand and contract within the steel bands, creating a tight seal that won’t shatter.
