How Much Space Do I Need for a 3-4 Person Infrared Sauna?

An approximate size guide for a spacious 4-person infrared sauna configuration is about 193cm wide, 149 cm deep, and 195cm high.

3-4 person infrared saunas require more space to accommodate more heating panels and a larger bench.

What Size is a 3-Person Infrared Sauna?

The average size of a 3-person infrared sauna is 59” L x 49” W x 75” H for standard models, and 59” L x 60” W x 75” H for corner sauna models.

That is approximately 5 ft by 5 ft. and over 6 ft tall.

They can accommodate up to 3 adults and allow all of them to get the maximum therapeutic benefits.

What Size is a 4-Person Infrared Sauna?

The average size of a 4-person infrared sauna is 69” L x 53” W x 75” H – approximately 5.75 ft. by 4.5 ft.

A corner 4-person sauna size is about 6′ 3” H x 4′ 11” W x 4′ 11” D.

Four-person saunas can be taller than average, with some models reaching a height of 85 inches.

How to Choose a 3-4 Person Infrared Sauna 

Infrared saunas come in a variety of sizes and shapes:

There are small (1-2 person) FIR saunas, large ones (3-6 person FIR saunas), portable saunas, corner infrared saunas, outdoor infrared saunas – anything you can think of.

3-4 person infrared saunas are larger, more stylish, and usually come with more carbon heaters and accessories (such as chromotherapy, an oxygen ionizer, an advanced sound system, etc.)

Here are the factors to check:

1. Material 

The 3-person infrared saunas you’ll find here are made with either Canadian Cedarwood or Canadian Hemlock.

Canadian Red Cedar is renowned for its beautiful color variation, refreshing aroma, and its resistance to rot and mildew.

It is durable and an excellent heat insulator.

Cedar also has antimicrobial properties that are anti-fungal as well as oils that aid in detoxification and is more expensive than Hemlock.

Hemlock has a great strength-to-weight ratio and is scent-free and hypoallergenic – a popular choice for the more affordable saunas.

No plywood or chemically treated wood is used in the construction of all the saunas in this list, and all of them have certification for their wood material – that outlines these factors.

2. Far Infrared Heaters

The best 4 people FIR saunas are equipped with carbon heaters, which heat up 30% faster than ceramic heaters and are energy-efficient.

All the saunas on this list have 7-10 energy-efficient carbon heaters inside, built to last for years.

3. EMF Radiation

EMF radiation varies and we found the EMF rating for each one of the saunas below – all of them are low, which makes these saunas safe to use.

Some FIR saunas are ultra-low EMF and usually cost more.

4. Infrared spectrum

Look for a sauna that offers a full spectrum of infrared wavelengths, including near, mid, and far. Each wavelength takes care of different aspects of overall health.

5. Accessories

Some saunas may come with additional features such as built-in speakers, chromotherapy lighting, or oxygen ionizers.

Consider which features are important to you and choose a sauna that offers them.

How Do You Clean and Maintain an Infrared Sauna?

To clean and maintain a 3-4 person infrared sauna, it’s important to wipe down the surfaces after each use (with a mix of white vinegar and water), vacuum the floor regularly to remove hair and dirt and dust the heaters every once in a while.

You can also use a towel to prevent sweat on the floor panel. It won’t stop you from absorbing the radiant heat.

If you have an oxygen ionizer (which eliminates germs, bacteria mold, and fungus), close the sauna door (once the vinegar odor dissipates) and turn it on for 15-30 minutes, to keep your sauna sanitary and fresh.

Do not use chemicals to clean your infrared sauna, and never hose down the interior or exterior.

To your health and happiness,
