4-Person Traditional Steam Sauna brings all the luxury and comfort at a more accessible price point. Bitumen roofing is not included. The pleasing barrel shape is both stylish and functional, providing maximum usable space while minimizing excess cubic feet. The fewer cubic feet of air, the faster your room will heat. This sauna can be placed indoors and outdoors. Its entrance features a full glass door with self-closing hinges to retain the heat of the room. The glass door is tempered to remain unfazed by the temperature changes. This sauna is powered by a 4.5 kW Harvia KIP 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 of your heater with an adjustable temperature range between 158-194 degrees Fahrenheit. The sauna rests on two wooden support cradles to preserve the wood and provide a solid foundation for the structure. This beautiful sauna is perfect for your front porch and back deck. Assembly can be accomplished in just a few hours and is very easy to do. It comes with an electrical 4.5 kW ETL-approved heater and stainless-steel components won't rust or harm the sauna. ALEKO is completely committed to providing you with saunas that are a lifetime investment in your health and serenity. Due to the nature of the 220V-240V hardwired heater unit, an electrician is recommended upon installation.
