What is the perfect sauna steam like?

This is a very common question among people building or renovating a sauna, or simply replacing an old heater. Just as there are many different sauna heaters, there are also many different sauna bathers. That is why perfect steam can be many things, as long as it is exactly the way each sauna lover prefers it.

A buyer may choose an electric sauna heater simply because installing a wood‑burning heater is not possible due to the absence of a flue. Even so, many believe that nothing beats the steam of a wood‑burning heater. Wood‑heated sauna steam is known for being long‑lasting and pleasantly moist. The good news for anyone who cannot install a wood‑burning heater is that electric sauna heaters can also produce long, soft, and humid steam.

A defining feature of Mondex electric sauna heaters is their perforated outer casing, which means the stones are visible not only from above but also from the sides. Because the stones are not covered by a solid casing, water can be thrown directly onto the stones from the sides of the heater. This allows for a wide range of different steam experiences. Pouring water toward the lower part and sides of the heater produces long, soft, and humid steam. Those who prefer stronger steam can achieve sharper and more intense sensations by slowly pouring water directly onto the top of the heater. Thanks to the perforated casing, a single heater can provide steam to suit many different preferences. For even softer and more humid steam, the top layer of stones can be supplemented with Mondex soapstone steam stones.

One of Mondex’s most distinctive innovations is the Rakka design sauna heater, shown in the image above. Its structure is patented and unlike traditional heaters, Rakka has no outer casing at all. From the outside, it appears to be made entirely of stones. The secret lies in the perforated stones that form the outermost layer. These stones are placed onto stainless steel rods, allowing them to remain securely in place while forming the heater’s outer shell. The combination of this patented structure and the heater’s massive stone capacity enables steam quality comparable to that of a wood‑burning sauna.

All Mondex sauna heaters are designed to produce steam for a wide variety of tastes. Assistance in choosing the correct heater power class is available from our heater selector . Simply enter your sauna’s dimensions and the materials used, and the selector will recommend Mondex heaters that are suitable for your specific sauna.
