ALEKO barrel sauna shape is both stylish and functional providing maximum usable space. The less cubic feet of air the faster your room will heat. The sauna rests on two weather resistant polymer support cradles to preserve the wood and provide a solid foundation for the structure. This sauna is powered by Electric Sauna Heater. Top-tier and Finnish-made this heater features corrosion-resistant stainless steel and includes a protective stone guard. With the included bucket and scoop pour water over the hot stones to boost atmospheric temperature and humidity. A simple-to-operate dial control allows for easy access and comfortable control to your heater with an adjustable temperature range between 158-194 degrees Fahrenheit. Assembly can be accomplished in just a few hours and is very easy to do. To comply with safety guidelines our heaters are designed to heat for a maximum of 60 minutes at a time. To heat your sauna for longer than 60 minutes simply reset the timer for additional time. Due to the nature of the 220V-240V hardwired heater unit an electrician is recommended upon installation.
