What Is an Infrared Sauna?
An infrared sauna uses infrared light panels to directly heat your body rather than heating the surrounding air. This means the cabin temperature stays lower, typically between 120°F and 150°F, while still producing a deep, penetrating warmth that many users find more comfortable than the intense heat of a traditional sauna.
Infrared saunas come in three wavelength categories: near-infrared, mid-infrared, and far-infrared. Most home models use far-infrared or full-spectrum panels. Far-infrared is the most studied and widely used, while full-spectrum models offer all three wavelengths for a broader range of potential benefits.
One of the biggest advantages of infrared saunas is accessibility. Most plug into a standard 120V household outlet, require no plumbing, and can be assembled by two people in under two hours.
What Is a Traditional Sauna?
A traditional sauna, sometimes called a Finnish sauna or steam sauna, heats the air inside the cabin using an electric heater topped with sauna stones. The air temperature typically reaches 150°F to 195°F, creating the intense, enveloping heat that sauna enthusiasts have enjoyed for centuries.
The defining ritual of a traditional sauna is löyly: pouring water over the heated stones to create bursts of steam.
Traditional saunas generally require more from your home's electrical system. Most models need a 240V dedicated circuit installed by a licensed electrician, which adds $200-$500 to the total cost.
“There's something about the ritual of heating the stones, pouring the water, and feeling that wave of steam that an infrared panel simply can't replicate.”
Infrared vs Traditional: Head-to-Head Comparison
The table below summarizes the key differences between infrared and traditional saunas across the factors that matter most to home buyers.
| Feature | Infrared Sauna | Traditional Sauna |
|---|---|---|
| Temperature Range | 120°F – 150°F | 150°F – 195°F |
| Heat-Up Time | 15 – 20 minutes | 30 – 45 minutes |
| Heating Method | Infrared panels (radiant heat) | Electric heater with stones (convection) |
| Electrical | 120V standard outlet (most models) | 240V dedicated circuit |
| Installation | DIY, plug-and-play | Professional recommended |
| Typical Session | 20 – 40 minutes | 15 – 20 minutes |
| Monthly Running Cost | $10 – $20 | $15 – $30 |
| Health Benefits | Deep tissue relief, detoxification | Cardiovascular, respiratory, muscle relaxation |
| Steam / Water | No steam (dry heat only) | Yes - pour water over stones for löyly |
| Price Range | $2,999 – $8,999 | $5,999 – $18,999+ |
Neither type is universally “better.” Each has distinct advantages depending on your priorities.
Which Type Is Right for You?
Choose Infrared If...
- You're new to home saunas and want a gentle introduction
- You have limited space (apartment, spare bedroom, garage corner)
- You don't want the hassle or expense of a 240V electrical upgrade
- You prefer longer, more comfortable sessions at lower temperatures
- You're primarily interested in targeted health benefits like pain relief and detoxification
Choose Traditional If...
- You want the authentic Finnish sauna experience with steam
- You prefer intense, high-temperature heat
- You have (or are willing to install) a 240V dedicated circuit
- You're building an outdoor sauna setup (pairs well with cold plunge)
- The ritual and experience matter as much as the physical benefits

Frequently Asked Questions
Can I use an infrared sauna and a traditional sauna interchangeably?
While both deliver heat-related benefits, the experiences are quite different. Infrared provides a milder, radiant heat that penetrates deeper into tissue, while traditional saunas surround you with high-temperature air and steam.
Are infrared saunas safe?
Yes. Infrared saunas are widely considered safe for healthy adults. The infrared wavelengths used in home saunas are the same type produced naturally by the human body and the sun (without UV radiation).
Which type uses less electricity?
Infrared saunas are significantly more energy-efficient. A typical infrared session costs about $0.50-$1.00 in electricity, while a traditional sauna session runs $1.50-$3.00.
How long do home saunas last?
A well-maintained home sauna should last 15-20 years or more. The wood requires occasional treatment, and heater elements may need replacement after 8-10 years of heavy use.
