The ONYX Platinum is the step up from the Gold — a higher-grade active chiller, superior insulation for better thermal efficiency, and a more refined external finish. For those who use cold therapy as a structured, daily protocol rather than occasionally, the Platinum's improved chiller performance and insulation make a practical difference: faster cool-down time, better temperature hold, and lower running costs over time.

The Platinum is designed for the serious cold therapy user — someone who treats the cold plunge as part of a wellness routine rather than a novelty. Built-in filtration. Delivered and installed by Medi-Spa's own team.*
