Why You Shouldn’t Convert an Infrared Sauna to a Traditional

Why You Shouldn’t Convert an Infrared Sauna to a Traditional

Infrared saunas lack steam and top out around 120-130 degrees F.  After experiencing an authentic sauna, many IR owners start to ask if they can convert the boxes to traditional saunas.

The short answer is no, but you can find ways to increase the heat.

Infrared sauna boxes are often made of the same wood, so it seems to make sense that they could be converted.

However, a traditional sauna has rocks that can be used to create steam by pouring water on them.  Finding a balance between heat and relative humidity is important – essential for a true sauna experience.

Unfortunately, an infrared sauna box is simply not designed to handle humidity.  Since there’s no vapor barrier in infrared saunas, a lot of humidity would escape and create problems in the surrounding rooms, and it could lead to mold and rotting wood.

Once your insurance adjuster traces the problem to your Frakensauna, you will be out of luck.

Converting to a traditional sauna would also create some airflow issues, which admittedly could be solved by adding proper ventilation.  Traditional saunas, especially wood-burning saunas need good airflow through the sauna rocks, and to feed the stove with oxygen.  They would typically require a ventilation inlet under the stove or low on the wall behind it, and another exhaust hole high on the opposite wall.

If you could create a vapor barrier and connect the exhaust hole to the exterior of the home, you might successfully convert an infrared sauna to a traditional sauna but we’ve never seen it done.

You can hack your infrared sauna to get hotter by insulating the top and adding another heater.  However, without the humidity you are not getting the steam required for a traditional sauna session.

Is an infrared sauna even a sauna?

Most Finnish people and sauna enthusiasts would reject calling infrared rooms saunas at all.  According to SaunaDigest, it’s not a sauna unless it can reach good temperature (160-200F), has rocks, and can create steam.

By definition, this is basically true – here’s from Dictionary.com



bath that uses dry heat to induce perspiration, and in which steam is produced by pouring water on heated stones.

Note: the pronunciation is another debate.
