Built sustainably using natural materials

With less unused space (imagine a circle inside a square), the barrel design lets the heater do its job faster and more efficiently. In a square sauna, the heat gets trapped at the ceiling. In a barrel sauna, the heat is pushed back down the curved sides and into the sauna as new heat rises from the heater.

The sauna door is made from 8mm tempered glass

Built with solid wood staves, the structural integrity of a barrel sauna withstands even the harshest outdoor environment.

The notched staves create a tight, secure fit that will last a lifetime without the excessive use of fasteners.

Cube Sauna

With the huge glass panel window, you can enjoy stargazing the night sky, watching the sunset or rise or simply enjoy the peace and quiet. It’s the perfect getaway for me time or to relax with friends and family.

Barrel Sauna

Our outdoor barrel sauna is the perfect addition to your outdoor living space.  Made from high quality,  thermo spruce, a barrel sauna not only looks great, it’s also the most efficient design for a sauna.
The round design of the barrel sauna helps to remove unused air spaces, so the sauna can heat up faster. The curved ceiling of the sauna also helps to naturally displace the rising hot air back to lower levels of the sauna.

The unique form of the fire chamber provides cleaner, more efficient combustion that meets CE markings for environmental friendliness.

Further enhancements to this elegant appliance include; a painted black finish on both sides, as well as cast iron details in front. Along with steel encasing surrounding each stone section, giving peace of mind when seeking optimal installation through adjustable feet and stability from rear connection pipes connecting directly to your chimney system for additional safety.

Harvia Cilindro Black Steel pillar heaters are ideal for a vast range of sauna requirements. Perfectly sized to provide an efficient and powerful saunatic experience, these stylish electric heaters offer flexibility in setup – easily embedded into your bench or elegantly displayed in front of the glass wall.
