Standard Sauna Size

There are two types of saunas to choose from, and they are the traditional and the infrared sauna.

A traditional sauna is higher in temperature, heats the body by heating the air. This type is temperature controlled by pouring water on to heated rocks.

An infrared sauna has a lower temperature and directly heats the body. This type is not temperature-controlled since it maxes out at a specific temperature. 

Regardless of the type to have, standard sauna dimensions are a common choice. The standard sauna has a size of 6 feet by 5 feet or 1.828 meters by 1.524 meters.

This layout size is perfect to fit up to four people. At the same time, the standard sauna ceiling height for this size is 84 inches or 213.36 centimeters.

Other than the traditional wood and stone steam room, infrared saunas use light to generate directly in your body. Infrared saunas do not warm the air around you as the conventional steam room does, so you get the benefits without the saunas warming the air inside the room. 

A benefit of an infrared steam room over the more traditional steam ones is they are relatively easier to install and transport without needing ample space for ventilation. This advantage means that an infrared steam room unit might be the better choice if you have limited space.
