The Kooru Cold Plunge Tub is a handcrafted cold water immersion tub built in San Diego from Shou Sugi Ban redwood — boards individually selected, fired, and sanded using the traditional Japanese charring method. It holds approximately 60 gallons, circulates water through a ¼ HP pump at 950 GPH, and uses an integrated ozonator for chemical-free sanitation. It runs on a standard 110V outlet and requires no professional installation.
Why This Cold Plunge Tub
