Infrared vs. Traditional Sauna: What’s the Difference?

If you're shopping for a home sauna, one of the first decisions you'll face is whether to choose an infrared sauna or a traditional sauna.

Both can create a relaxing sauna experience at home, but they work differently. They use different heating methods, typically operate at different temperatures and may have different installation and electrical requirements.

Understanding those differences can make it much easier to decide which type fits your home and preferences.

How Does a Traditional Sauna Work?

A traditional sauna uses a heater to warm the air inside the sauna. The heated air then raises the temperature of the space and warms the people inside it.

Traditional saunas are known for the classic high-temperature sauna experience.

Depending on the sauna design, some traditional heaters also allow water to be added to heated sauna stones to temporarily increase humidity and create steam.

If you enjoy a hotter environment and the classic feel associated with traditional saunas, this style may appeal to you.

How Does an Infrared Sauna Work?

Infrared saunas use infrared heaters that emit radiant energy.

Rather than primarily heating the surrounding air first, infrared energy warms the body more directly. Because of this difference, infrared saunas generally operate at lower air temperatures than traditional saunas.

Many homeowners like infrared saunas because they can provide a warm sauna experience without requiring the higher air temperatures associated with a traditional sauna.

Infrared vs. Traditional Sauna Temperature

Temperature is one of the biggest differences shoppers notice.

Traditional saunas generally operate at higher temperatures, while infrared saunas typically provide their experience at lower ambient temperatures.

That doesn't necessarily mean one is better than the other. It comes down largely to the type of environment you prefer.

Someone who enjoys intense heat may prefer a traditional sauna, while someone who prefers a lower-temperature environment may be more comfortable with infrared.

Always follow the operating temperature recommendations provided by the manufacturer of your particular sauna.

What Is a Full-Spectrum Infrared Sauna?

As you compare infrared saunas, you'll probably also encounter full-spectrum infrared saunas.

Infrared is commonly described in three wavelength ranges:

Near infrared
Mid infrared
Far infrared

A full-spectrum sauna is designed to incorporate multiple infrared wavelength ranges, typically near, mid and far infrared.

Other infrared saunas may primarily use far-infrared heating.

When comparing them, look beyond the words “full spectrum” and examine the actual heater configuration and specifications for each model.

What About Low-EMF Infrared Saunas?

Another term you'll frequently see while shopping for infrared saunas is EMF, which stands for electromagnetic field.

Manufacturers may describe their saunas using terms such as low EMF, ultra-low EMF or near-zero EMF.

Because terminology and testing methods can vary among manufacturers, compare the published specifications for the individual sauna you're considering rather than relying only on the label.

We'll cover EMF ratings in more detail in a separate sauna guide.

Installation and Electrical Requirements

Before choosing either type of sauna, check the electrical requirements for the exact model.

Requirements can vary based on sauna size, heater configuration and power demands.

Some models may work with relatively common residential electrical configurations, while others may require a dedicated circuit, different voltage or professional electrical work.

Never assume two similarly sized saunas have identical requirements.

Check the manufacturer's specifications before purchasing and consult a qualified electrician if you're unsure whether your home's electrical system can accommodate the sauna.

Indoor vs. Outdoor Placement

Both sauna type and location matter.

Some saunas are specifically designed for indoor installation, while others are constructed and rated for outdoor environments.

Before purchasing, consider:

• Available floor space
• Ceiling height
• Door and hallway clearance
• Electrical access
• Manufacturer clearance requirements
• Indoor or outdoor rating

An indoor sauna shouldn't automatically be assumed suitable for outdoor installation.

Which Sauna Is Right for Your Home?

Instead of asking which type of sauna is universally “better,” consider which experience and setup better match your home.

An infrared sauna may appeal to someone who prefers lower ambient temperatures or wants the features offered by many modern infrared models.

A traditional sauna may appeal to someone looking for the classic hotter sauna environment.

Your available space, electrical setup, preferred heat experience, sauna size and budget can all help narrow the decision.

Compare Home Sauna Options

Choosing between infrared and traditional heat is an important first step, but it's only part of selecting a home sauna.

You'll also want to compare size, heater technology, EMF specifications where applicable, electrical requirements, installation location, construction, features and warranty.

Taking the time to compare those specifications can help you choose a sauna that fits both your home and the experience you're looking for.
