Lifetime Warranty

Your Clearlight infrared sauna comes with a complete lifetime warranty on every single component. Few other companies can offer this level of warranty because no other brand builds saunas with the caliber of craftsmanship that Clearlight prides itself with.

True Wave™ infrared heaters have an estimated operational life of at least 30,000 hours. With daily sauna use, these heaters will last over 100 years. All Clearlight sauna cabins are both kiln dried and air dried to 7% moisture content then each panel is pressed. This process prevents any warping or cracking of the wood. All electrical components in your Clearlight sauna are manufactured to exacting standards and every sauna is tested and run for several hours before it ships out.

In the rare event an issue occurs with your sauna, the lifetime warranty covers the entire sauna - heaters, controls, electrical components, and wood, as well as the built-in audio system. With Clearlight, you can be confident that you’re making an investment that will last a lifetime.

Infrared Sauna Benefits

Weight Loss Promotion

Infrared rays deeply penetrate the body, increasing metabolic rate and helping burn off hundreds of calories in just one half-hour session!

Increased Longevity

Regular infrared sauna therapy has the potential to significantly increase length and quality of life through decreasing inflammation and oxidative damage.

Lower Risk of Disease

Studies show that those who use a sauna four to seven times a week may have a 66% decrease in risk of dementia and a 65% decrease in risk of Alzheimer’s disease.

Stress Relief, Relaxation, and Sleep

Regular sauna use helps moderate your body's level of cortisol, the primary stress hormone. This helps you feel more relaxed and sleep more deeply throughout the night.

Optimal Skin Health

Studies show that regular sauna use can help eliminate rashes or irritated skin, blemishes, and aging. Through enhanced collagen production, overall elasticity and appearance of the skin is vastly improved.

Immunity Boost

Through toxin elimination, increased white blood cell production, and cellular energy creation, the immune system is strengthened and antibodies are stimulated, helping fight infections and disease.

Chronic Pain Treatment

In addition to increased flexibility and range of motion as well as decreased joint stiffness and inflammation, a Japanese study showed that chronic pain patients experienced a significant reduction in pain levels (nearly 70%). Infrared sauna use is also known to treat sports injuries, chronic fatigue syndrome, fibromyalgia, arthritis and other acute pain conditions.

Improved Mood

Regular sauna use helps stimulate “happy chemicals”, like dopamine and serotonin. In one published study, participants that had just one infrared sauna treatment reduced their symptoms of depression by about 50%. Saunas make you happy!

Superior Craftsmanship & Unparalleled Innovation

Designed by doctors and endorsed by highly-esteemed health practitioners and athletes, Clearlight saunas are built using the highest quality materials and technologies available.
