Recovery Lab is Sammamish's premier indoor sauna and cold plunge studio, founded by locals Nathan Harrison and JC Abboud. Rooted in the science of contrast therapy, Recovery Lab offers a custom-built sauna and three state-of-the-art ReGen Commercial Blast Pro cold plunges designed to amplify the body's natural healing process. Each one-hour session is entirely self-guided — no timers, no staff rotations — giving members the freedom to alternate between heat and cold at their own pace. Open seven days a week from 7am to 8pm, the studio serves athletes, tradespeople, desk workers, parents, and retirees alike. With towels, electrolyte water, showers, and ADA-compliant locker rooms included, Recovery Lab delivers a true retreat experience on the Sammamish Plateau.
