Full Spectrum Infrared Saunas for Sale
Full-spectrum infrared saunas add near- and mid-infrared emitters to the far-infrared carbon panels of a standard unit. Near infrared is associated with skin and surface benefits, mid infrared with circulation, and far infrared with the deep, sweating heat most people expect from a sauna.
Compare the number and placement of full-spectrum emitters (usually on the front wall near the door), whether the near/mid elements can be controlled independently, cabin size and wood species. Most models remain 120 V plug-in units with low-EMF far-infrared panels.

More About Full Spectrum Infrared Saunas
The full-spectrum elements are typically halogen or ceramic heaters that run hotter than carbon panels and reach operating temperature faster, so the cabin warms quickly and users feel a more intense, radiant heat on the front of the body. Some units let you run far-infrared only for a gentler session.
If you are choosing between a full-spectrum unit and a standard far-infrared unit at the same size, the full-spectrum sauna costs more but offers a broader range of heat experiences. For pure relaxation and sweating, a far-infrared low-EMF unit is sufficient; for a more therapeutic, spa-style setup, full spectrum is worth the difference.
Frequently Asked Questions
What are the three infrared wavelengths?
Near infrared (shortest, penetrates the skin surface), mid infrared (moderate penetration, associated with circulation) and far infrared (longest, gentle radiant heat that raises core temperature and induces sweating).
Are full-spectrum saunas hotter?
The air temperature range is similar (up to about 150°F) but the radiant heat from the near/mid emitters feels more intense on the skin.
Do full-spectrum saunas require 240 V?
Most 2–3 person units still run on a dedicated 120 V / 20 A circuit. Larger models may need 240 V — check the product page.
