Infrared vs Traditional Saunas: What’s the Real Difference

Saunas have supported warmth, recovery, and ritual for centuries. Today, most people choosing a home sauna land on one of two paths: infrared or traditional. Both offer meaningful benefits, but the heat style, atmosphere, and installation needs are very different.

This guide explains how each type works, what the heat feels like, and how to choose the style that fits your space and routine.

 

What Is a Traditional Sauna

A traditional sauna, often called a Finnish sauna, uses a heater to warm a large mass of stones. The stones heat the air, and the air warms your body. When you pour water over the stones, you create soft, enveloping steam known as löyly.

How Traditional Saunas Work

• A heater warms a basket of stones
• Stones heat the air to 170 to 200 degrees Fahrenheit
• Water on the stones creates steam
• The heat feels full, atmospheric, and immersive

What the Heat Feels Like

Traditional heat surrounds the body. Steam softens the intensity and creates a sensory, restorative experience.

Why People Choose Traditional Saunas

• Rich, full body heat
• Steam on demand
• A strong sense of ritual
• Ideal for outdoor installations
• Naturally pairs with cold therapy

Considerations

• Higher power or ventilation requirements
• Longer heat up time
• More involved installation

What Is an Infrared Sauna

Infrared saunas use panels that emit infrared wavelengths. These wavelengths warm the body directly rather than heating the air. The room stays cooler, usually between 120 and 140 degrees Fahrenheit, while your body absorbs the infrared energy.

How Infrared Saunas Work

• Panels emit near, mid, or far infrared wavelengths
• Heat penetrates the skin directly
• Air temperature stays lower
• No steam is produced

What the Heat Feels Like

Infrared heat is gentle and targeted. You feel warmth in your muscles without the intensity of hot air. Sessions feel quiet, calm, and meditative.

Why People Choose Infrared

• Lower temperatures feel more accessible
• Quick heat up time
• Simple installation
• Works well in small indoor spaces

Considerations

• No steam
• Less atmospheric than traditional
• Not ideal for outdoor use unless fully enclosed

 

Can You Combine Infrared and Traditional Heat

Yes. A combination sauna gives you both heat styles in one space. Your FD 4 Full Spectrum 2 Person Trinity Infrared and Steam Sauna Combo Kit is a true hybrid system. It includes full spectrum infrared panels along with a traditional heater and stones for steam.

How a Combo Sauna Works

• Infrared panels warm the body directly
• A traditional heater warms the stones and the air
• Adding water to the stones creates steam
• You can run infrared alone, traditional heat alone, or both together depending on your preference

Why People Choose a Combo Sauna

• Maximum flexibility
• Infrared sessions for gentle, targeted warmth
• Traditional sessions for steam and atmosphere
• One room that supports multiple routines
• Ideal for households with different heat preferences

What the Experience Feels Like

Infrared provides a calm, steady warmth. Traditional heat adds atmosphere, steam, and a fuller thermal experience. Together, they create a versatile space that supports both quick sessions and longer, more immersive rituals.

 

Infrared vs Traditional vs Combo: Key Differences

1. Heat Style

• Traditional: Hot air and steam with an immersive feel
• Infrared: Direct body warming with gentle, lower air temperatures
• Combo: Both heat styles in one room. Infrared panels warm the body directly, and the traditional heater warms the stones and the air for steam when desired

2. Temperature Range

• Traditional: 170 to 200 degrees Fahrenheit
• Infrared: 120 to 140 degrees Fahrenheit
• Combo: Supports the full range. Infrared sessions stay in the lower range, and traditional sessions reach higher temperatures when the heater and stones are used

3. Steam

• Traditional: Yes
• Infrared: No
• Combo: Yes, when using the traditional heater and stones. Infrared sessions remain dry

4. Installation

• Traditional: Requires ventilation, higher power, or a chimney depending on the heater type
• Infrared: Simple plug in or a dedicated circuit
• Combo: Requires electrical support for infrared panels and proper installation for the traditional heater. Still simpler than installing two separate rooms

5. Experience

• Traditional: Ritual driven, sensory, and atmospheric
• Infrared: Quiet, calm, and introspective
• Combo: Flexible and adaptable. You can choose a gentle infrared session, a full traditional session with steam, or alternate between both depending on your routine

 

Which Sauna Is Right for You

Choose a Traditional Sauna If

• You love steam
• You want a classic sauna experience
• You enjoy ritual and atmosphere
• You are building outdoors
• You want the hottest temperatures
• You want a heater and stones that create a full, immersive climate

Choose an Infrared Sauna If

• You prefer lower temperatures
• You want quick heat up
• You are installing indoors
• You want a simple, low maintenance setup
• You like gentle, targeted warmth without steam

Choose a Combo Sauna If

• You want both infrared and traditional heat in one space
• You want the flexibility to choose your heat style each session
• You share the sauna with someone who prefers a different type of heat
• You want a single room that supports multiple routines
• You want the benefits of full spectrum infrared along with steam and atmosphere
• You want a future proof setup that adapts to changing preferences

 

The Bottom Line

Both infrared and traditional saunas offer meaningful benefits, but the experience is completely different. Traditional saunas deliver heat, steam, and ritual. Infrared saunas offer gentle warmth and simplicity. Combo saunas bring both experiences into one room and allow you to choose the heat style that fits your routine that day.

All three options support relaxation, recovery, and meaningful time in heat. The right choice depends on your space, your preferred temperature range, and the type of experience you want to create. Explore our saunas here.
