The Original Coldtub

We make advanced hydrotherapy pools, tubs for professional and amateur athletes.

COLDTUB™ designs and manufactures cold water therapy products (aka cryotherapy, cold water immersion, balneotherapy, hydrotherapy). Our flagship product, the POLARPOOL® COLDTUB™ was inspired by Don DelNegro, head Athletic Trainer for the Boston Bruins hockey team, as he searched for a better alternative to common steel whirlpools for his athletes. Don, like many other trainers, was concerned about the safety, sanitation, size, chemical maintenance, and set up time required by traditional cold water tanks.

Our Story

COLDTUB™ designs and manufactures cold water therapy products (compared to: cryotherapy, cold water immersion, balneotherapy, hydrotherapy). Our flagship product, the POLARPOOL® COLDTUB™ , was inspired by Don DelNegro as the head Athletic Trainer for the Boston Bruins hockey team; he searched for a better alternative to common steel whirlpools for his athletes. Don, like many other trainers, was concerned about the safety, sanitation, size, chemical maintenance, and set up time required by traditional cold water tanks.

“We now have more than half our team taking cold plunges as part of their recovery program and utilizing its benefits daily. We could not be more happy with the results we have seen in our players and the teams' success.” -Don DelNegro, MS, ATC (L), CSCS

COLDTUB™ streamlined and perfected the art of using a whirlpool at your own convince to help foster the best performance an athlete needs to compete at the highest level. The incredible benefits can be realized by anybody who seeks a high level of physical performance, faster recovery, and rapid rehabilitation. So far, professional sport teams, college sport departments, physical therapists, sports medicine facilities, hospital-based rehab clinics, military, individuals, and training facilities are utilizing COLDTUB™ cold water products.

The extremely compact size and portability make it suitable for even recreational athletes who simply want to recover rapidly from their sport so they can get back out there doing what they love, faster, healthier, and with less pain.
