A home sauna can also increase the value of your home. It is relatively easy to maintain with considerably smaller upkeep compared to a swimming pool or even a hot tub. 

Once you have decided to build or install a sauna for your home, whether indoors or outdoors, the first step is deciding what size you want it to be.

There are a lot of factors to consider, and the biggest one is the size. In this article, we will provide you with the measurements that could help you decide on the right size sauna for your home.

Standard Sauna Size

Standard sauna sizeThere are two types of saunas to choose from, and they are the traditional or 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, there are standard sauna dimensions that are a common choice among sauna-having households. The standard sauna room has a size of 6 feet by 5 feet or 1.828 meters by 1.524 meters.

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

Couple Sauna Dimensions

If you are a couple looking to get a sauna for your home or if you plan on lying down on the room while the sauna does its magic— a 2-person sauna is perfect for you. 

For a compact traditional 2-person sauna, dimensions are usually 4 by 4 feet or 48 by 48 inches and 6 feet or 72 inches high. 2-person traditional indoor saunas usually have a dimension of 1.2 by 1.2 meters and are a good 1900 millimeters or 1.9 meters high. 

In comparison, an indoor infrared sauna has dimensions of 3.33 by 4 feet or 40 by 48 inches. For an outdoor sauna that could fit two persons, the dimensions are slightly higher, being 4 by 5 feet or 48 to 60 inches. 

A 2-person traditional outdoor sauna usually comes with a size of 1.2 by 1.5 meters, while indoor infrared saunas for two persons usually have dimensions of 1.01 by 1.2 meters. 

Dimensions for Sauna Good for 4 Persons

4 person sauna dimensionsSaunas are also great for entertaining your closest friends and other family members. One of the great benefits of a sauna is that it builds up the immune system, and if you are a family with kids nine years old and above, this will be a great way to create healthy habits and protect them from diseases.

Just remember to make sure that they are in the lower part and that steam is kept to a minimum since younger kids can’t regulate heat yet as efficiently. 

These are the dimensions for different types of four-person saunas. The dimensions of a traditional indoor sauna are 5 by 7 feet or 60 by 84 inches. They typically have a height of 7 feet or 84 inches. Traditional indoor saunas, are usually 1.52 meters by 2.13 meters and have a height or depth of 2.15 meters. 

On the other hand, a traditional outdoor sauna will be perfect because you won’t have to renovate it indoors. The size is usually 6.5 by 7 feet or 78 by 84 inches, and they also have a height of 7 feet or 84 inches. 

Traditional steam saunas for outdoors have metric dimensions of: 1.97 by 2.10 meters with a height 2.15 meters. 

For indoor infrared saunas, the dimensions are as follows: a vertical length of 4.67 feet or 1.42 meters, a horizontal width of 6 feet or 1.83 meters, and a depth from top to bottom of 6.36 feet or 1.94 meters. 

In contrast, an indoor infrared sauna has dimensions of 4.7 feet 56 inches in length, a width of 6 feet or 72 inches, and a top to the bottom depth of 6 feet or 72 inches. 

Sauna Measurements Fit for 6 People

For the whole family or a group to enjoy the great benefits of a sauna, one should be big enough to accommodate everyone first, and a six-person sauna is probably what would best fit everyone. 

This size is not big enough to resemble the industrial, commercial saunas, but it is a luxurious site when found in homes. Not only will everyone be able to enjoy the benefits, but great conversations can be had with all the available space. 

The dimensions of a six-person traditional indoor sauna that uses wood and sauna rocks are usually 6 by 8 feet or 72 by 96 inches.

You can allot 2 feet or 24 inches of space to make room for the sauna rocks container and an entryway to the sauna of 2.17 feet or 26 inches—the rest of the 3.83 feet or 46 inches space can be used for built-in seating. 

Size of Sauna to Accomodate 8 People

There is even a choice to go up to 8 by 8 feet or 96 by 96 inches to accommodate six to eight persons. 

Infrared Sauna Dimensions

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

A benefit of an infrared sauna 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 sauna unit might be the better choice if you have limited space. 

Sauna Bath Room Size

There’s no need for an outside spa treatment when you can have all the tools to enhance relaxation in one room. The wood of the sauna will also accentuate every bathroom’s aesthetic, no matter what your bathroom’s design is. 

Saunas installed in the bathroom are usually saunas that could fit a single or a couple of persons. Read more about bathroom sizes on this page.

For a single person in-bath sauna, the dimensions can range from 3 by 3 feet to 4 by 5 feet. Anything more extensive than that would be made to measure for your bathroom and would depend on what you want and how much you are willing to pay to have your vision come to fruition. 

Sauna Bench Dimensions

Sauna Bench DimensionsThe sauna seat or bench is essential to get the total relaxation and health benefits that a sauna gives, so ample space is needed to make way for a sauna bar.

Ample space for planning your home sauna is space allotted for the bench. Ideally, you would need 2 feet or 24 inches of bench space for a single person and to recline comfortably as they use the sauna.

An area of 6 feet or 72 inches in one direction is advisable if you have the room to account for it. If you have room, 6 feet or 72 inches of wall-to-wall bench will allow multiple persons to be seated. 

Sauna Bench Height

If you are going for a sauna with two bench heights, the upper bench should be at least 36 inches or 3 feet high, while the lower bench should have a height of 18 inches or 1.5 feet. 

There are also sauna benches with multiple heights, although climbing with hands is only supported. The upper bench of the sauna should be 36 inches or 3 feet high, while the lower bench should be 1.5 feet tall or 18 inches.

Whatever your sauna room height is, you can choose to go up to 3 benches high for multiple seating and laying down options. 

Sauna Room Size

Aside from the sizes mentioned above, other sauna rooms are available to fit your entire family and a party!

You could go for 4×6 ones to seat three persons to 8×12 ones to fit every single one of your 12 girlfriends for girl’s night. Just determine the number of people, what type of sauna you want, your budget and the rest will follow.

How Big Should a Sauna be?

An area outdoors is foolproof and could follow the exterior design of your house so it wouldn’t stand out, but for indoor saunas, they have a lot of space requirements you should account for. 

This includes space easy enough to have access behind your sauna room for maintenance, especially for infrared sauna types. 

Your budget is another option since there are ready-to-install saunas for the person in a budget, while people with an endless amount of budget allocated can go for custom sizing saunas. If you are redesigning or creating a sauna room there are bathroom remodel software apps, that can make the process much easier to visualize.

Benefits of a Sauna at Home

Relaxation is the first benefit that comes to mind when the sauna is in question, but aside from relaxation, saunas carry a lot of health benefits. The sweating brought about by the dry heat rids of the body’s toxin poses many cardiovascular health benefits, same as exercising. 

Saunas are also known to ease pain by increasing blood circulation to the sore spot and thus making it great for people with arthritis. A two-person sauna will be perfect for smaller homes and for couples who will be using the facilities. 

An addition of a sauna in your home can increase its value if you choose to sell in the future. Saunas are also great for entertaining your closest friends and family members over the age of nine.

Are Saunas Healthy to Use

A sauna may work to build up an immune system to fight diseases, and will also create a great habit that your kids can take as they grow older. 

To make it safe for a younger family member, it’s essential to situate the heat more on the lower part and opt for a steam sauna for safer use and efficiency. 

How to Choose Sauna Dimensions

The decision is heavily dependent on how much space you have and how many people are in your immediate family, and how often you would like to host for other friends and families. Once you factor in that number, sizes will be easier to consider. 

If you have a family of four or more, there are infrared saunas available that are 5.74 by 4.5 feet and 6 feet tall, so no ducking as you enter the sauna.

A family of three corner infrared saunas 5×5 feet would work great. If you live alone, there are 1 to 2 person saunas 3×3 or 4×4 feet and will be ideal for you. 

Are Saunas a Good Idea?

Saunas are a good idea overall; they will give you a lot of health benefits, they are low-maintenance, and they will even add to the value of your home. 

Let’s take a cue from the Finnish culture and adopt sauna into our lifestyle as they are known to release endorphins which will decrease stress. After all, Finland is the Happiest Country in the world. Happy steaming!
