A traditional sauna experience is defined by its powerful heater, which warms a large compartment of sauna stones to very high temperatures. The magic happens when you ladle water onto these stones, creating a burst of soft, enveloping steam known as "löyly." This combination of high heat and humidity is the hallmark of the authentic Finnish sauna.
The intense heat and steam of a traditional sauna provide a powerful, detoxifying sweat that helps cleanse the body and relax the muscles. The steam is also excellent for respiratory health, helping to open up airways and soothe sinuses. For many, the ritual of creating steam and enjoying the robust heat is a deeply satisfying and invigorating wellness practice.
The size of your sauna cabin determines the power (kW) of the electric sauna heater you'll need. A larger room requires a more powerful heater to ensure it heats up efficiently. To find the exact heater size required for your specific sauna, we strongly recommend using our official sauna heater size calculator for a perfect match.
Due to the powerful heaters needed to achieve high temperatures, a traditional indoor sauna always requires a dedicated 240-volt circuit. This is a significant electrical installation that must be completed by a licensed electrician to ensure your home can safely support the power draw and that all connections are up to code.
