About 490 LAB – Sauna + Cold Plunge Studio
490 LAB is a dedicated sauna and cold plunge studio in River Edge, NJ, operating under the tagline of science-based heat and cold exposure for health and longevity. The studio offers private sessions combining a real dry sauna with a true cold plunge, distinguishing itself from facilities that use infrared or approximations of cold therapy. Each 60-minute booking reserves a private room equipped with Bluetooth speakers and towel service. Sessions are designed around deliberate thermaculture protocols, allowing clients to complete two to three full heat-cold cycles. Owner Josh guides first-time and returning clients on optimal protocols based on current research. The studio is conveniently accessible with early morning start times and operates seven days a week. Online booking is required in advance, with a waitlist available for last-minute openings. Gift cards are available. Reviews consistently highlight the private, distraction-free environment and the quality difference of using genuine cold plunge and dry sauna equipment. 490 LAB is especially well-suited for athletes in recovery, longevity-focused individuals, and those exploring contrast therapy for the first time.
