Take your recovery routine to the next level with the One Theory Wellness Regen 400 Cold Plunge Tub. Designed to deliver a superior cold therapy experience, this tub combines performance, comfort, and durability in one powerful package.

Built chiller-ready and fully foam-insulated, it holds the cold far longer than uninsulated barrels or inflatable baths, ensuring a refreshing plunge whenever you need it. With a 400-quart (100-gallon) capacity, it comfortably fits users up to 6'3" and 300 pounds. Despite its spacious interior, the tub stays compact at just 48" x 28" x 28", making it a perfect fit for your garage, gym, backyard, or outdoor setup.

Proudly crafted in the USA, its molded construction and reinforced insulation provide long-lasting durability for daily use. Whether it’s for sports recovery, post-workout relaxation, pain relief soaks, or building resilience, this tub adapts seamlessly to your lifestyle.

Maintenance is simple, with a design that’s easy to clean and care for. Pair it with our 1.0 HP Chiller system (included with chiller orders) to cool water down to 37°F. Every system comes equipped with a 650 GPH pump and 20-micron filtration system, keeping your plunge water clear and refreshing.
