Clearlight Launches Premium Cold Plunge to Complement Its Infrared Sauna Lineup

For nearly three decades, Clearlight has led the infrared sauna category by designing wellness technologies that work together. Now the Berkeley, California company is moving into cold water. Clearlight announced the launch of the Clearlight Plunge, a premium cold plunge designed to complete the pioneering brand's ecosystem of modern wellness and recovery.

The pitch here is specific: this isn't a standalone ice bath tossed into a product lineup. The company already combines infrared heat, red light therapy, halotherapy, aromatherapy, and vibrational resonance therapy to maximize benefits within a single session, and the introduction of the Clearlight Plunge brings cold therapy into this wellness and recovery ecosystem. Dr. Raleigh Duncan, Clearlight's founder, framed it plainly: "When heat, cold, and light are designed to work together, the body responds more efficiently. The Clearlight Plunge completes this equation."

On the hardware side, the Plunge is built with a stainless steel basin and a handcrafted Canadian cedar exterior, arriving fully assembled with no additional plumbing required. It only requires filling with water and plugging into a standard 120V socket. That's a meaningful spec for anyone who has priced out plumbing work. The temperature range runs from 37.4°F to 107.6°F, offering both cold and warm therapy options. The warm ceiling means you can use it as a hot soak on the same day you do a cold plunge protocol, which makes it more versatile than a dedicated chiller-only unit. The sanitation system uses a double-cleaning setup that includes an ozone generator and dual filtration, ensuring the water remains clean and safe with minimal manual maintenance. Control runs through the SmartLife app.

The ergonomic design includes a natural seated position that eliminates buoyancy issues, it can accommodate one or two people with an optional removable seat available for purchase, and the depth allows for full-body immersion and comfort. Duncan added: "Cold therapy should never feel like punishment; rather, like all wellness solutions, it should feel purposeful and a part of your overall health routine."

When paired with Clearlight infrared sauna heat and red light therapy, cold exposure becomes part of a larger recovery protocol designed to support both physical performance and nervous system regulation, according to Duncan. That integration positioning is what Clearlight is leaning into hardest. The contrast therapy conversation has moved well beyond athletic recovery circles into longevity, biohacking, and general home wellness, and Clearlight is betting that buyers who already own one of its saunas will want a matched cold plunge rather than a mismatched third-party tub.

Orders opened March 25, 2026. An Easter Sale runs through April 6, saving buyers $400 off MSRP, or $1,000 off the Plunge when purchasing a sauna at the same time. The $1,000 bundle discount is the sharper deal if you've been sitting on a sauna purchase anyway. Clearlight has not published an MSRP in its launch materials, so contacting the company directly is the current path to pricing. Commercial buyers can access bulk pricing through Clearlight's Wellness Innovations team.
