How to Pick Out the Right Sauna Size?

Sauna size

Once you have decided to install a sauna, you should find the right place for it first. Most residential saunas are 7 feet (2.1 m) high and measure 6 by 6 feet (1.8 x 1.8 m). That size allows you to install both top and bottom benches with enough space for the heater.

You can ask for some adjustments if you need only one but longer bench for comfortable lying down. In most cases, variations less than 20 inches (0.5 m) won’t significantly affect the final price. However, you should count on a larger heater size than standard.

The best option is to pick out sauna size based on the number of people who will use it simultaneously. Remember that a larger sauna is more comfortable, but it will be more expensive since it requires more fuel. You have a few models at your disposal, including:

  • Single tier
  • Double tier
  • Double tier 5-sided
  • Double tier with return
  • Double tier 5-sided with return
  • Double tier L shaped
  • Double tier U shaped

Number of people

The number of people who will use your new sauna at once is a critical factor you should take care of. Firstly, it is necessary to determine space according to the number of people and add about 50 inches (1.3 m) distance from the heater.

Secondly, you should be precise whether you need space for lying down or sitting. Finally, you should think about leaving room for an outward opening of the door without blocking anything.

Sauna height

The height of each particular model will directly affect the result you want to get in your sauna. As you know, hot air always rises toward the ceiling. So, a too high sauna will require a bigger heater, or the existing one needs to work harder. As a result, you will get a higher electricity bill to keep desired temperature levels.

Another problem is ​underpowered models, especially those working on gas. They may activate an emergency switch, so you will need to reset your sauna in the middle of relaxing time. Therefore, you should always look for a sauna model with an ideal 7 feet (2.1 m) high ceiling for maximum pleasure at an affordable price.

Sauna area

You should be aware that you need to think of two dimensions when calculating sauna size:

  • Inner dimension

The rule of thumb is to choose a model with at least one side long, an ideal 81 3/4 inches (2 m). That length will allow you to comfortably lay down and spend a relaxing time without bending the legs or awkward body positions.

On the other hand, you can plan a smaller model if you want to use it in a sitting position. When you need a spacy model for a family or gathering with friends, you should choose models for five to ten people.

  • External dimension

It may seem to you that there is no significant difference between inner and external sauna dimensions. However, miscalculation will potentially complicate your life. Unlike inner sizes adjusted to your comfort, external sizes should fit where you want to install a sauna.

In other words, you should know that a standard sauna wall thickness is 3 inches (8 cm). Plus, it is necessary to add wall spacing of 6 cm when you want to connect a sauna to a room wall.

Keep in mind that all given dimensions are for inner sauna size. So, you need to do some math to get the required external measures.
