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 more accessories (such as chromotherapy, advanced sound system, etc.)

The 3 person infrared saunas you’ve found 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 microbial 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, 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.

Far Infrared Heaters

The best 4 people FIR saunas are equipped with carbon heaters, that 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.


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.
