If you’re deciding between an infrared sauna and a traditional sauna, the biggest difference is how the heat is produced and how it feels during your session.
Both types use heat to promote sweating and relaxation. The overall experience, temperature range, and installation requirements are what set them apart.
How a Traditional Sauna Works
A traditional sauna uses an electric heater to warm the air inside the room. The heater warms sauna stones, and water can be poured over the stones to create steam.
• Typical effective temperature range: 150°F to 195°F
• Heats the air first, then your body warms from the surrounding heat
• Can create steam and humidity
• Usually requires 30 to 45 minutes to fully preheat
This creates a high-heat environment often associated with the classic sauna experience.
How an Infrared Sauna Works
An infrared sauna uses infrared heaters that emit infrared light waves. These waves warm your body more directly instead of heating the air first.
• Typical effective temperature range: 120°F to 150°F
• Heats the body more directly
• Dry heat only, no steam
• Often has a faster heat-up time than traditional saunas
Because the air temperature is lower, many users find infrared sessions more comfortable for longer periods of time.
Key Differences at a Glance
Heat delivery
Traditional: heats the air
Infrared: heats the body more directly
Temperature
Traditional: higher overall air temperature
Infrared: lower ambient temperature
Humidity
Traditional: can include steam
Infrared: dry heat
Heat-up time
Traditional: longer preheat time
Infrared: typically faster
Installation & Electrical Requirements
Installation requirements vary depending on the model and size of the sauna.
Traditional saunas:
• Typically require a dedicated electrical circuit
• May require professional installation
• Often need additional ventilation considerations
Infrared saunas:
• Smaller models may plug into a standard household outlet
• Larger models may require a dedicated electrical circuit and upgraded outlet receptacle
• Electrical requirements vary by size and heater configuration
We recommend reviewing the electrical specifications for your specific model before purchasing. For a more detailed breakdown of sizing, power requirements, and space planning, please see our Infrared Sauna Buying Guide or contact our team for assistance.
Frequently Asked Questions
Is one type of sauna better than the other?
Neither option is universally better. The right choice depends on your temperature preference, desired session length, installation setup, and overall comfort level.
Do infrared saunas get as hot as traditional saunas?
No. Infrared saunas operate at lower air temperatures. However, because the heat warms the body more directly, many users still experience a strong sweat response. Infrared saunas are effective at much lower temperatures.
Can I pour water on the heaters in an infrared sauna?
No. Infrared saunas are designed for dry heat only. Water should never be poured on infrared heaters.
Do infrared saunas require special wiring?
It depends on the model. Some smaller units can plug into a standard household outlet. Larger models may require a dedicated electrical circuit or upgraded outlet receptacle. Always review the product specifications directly on the website before purchasing.
Do traditional saunas require ventilation?
Traditional saunas often require more ventilation planning due to higher heat and steam use. Requirements vary depending on installation location and model.
