Dynamic Cold Therapy Inflatable Plunge review

The Dynamic Cold Therapy Inflatable Plunge is the cheapest tub on this list and the only one designed to travel. Dynamic Cold Therapy sells it for $899 and says it inflates in seconds and packs into a single backpack, with a hand pump, custom flooring and a lockable childproof cover in the box. The company describes the material as military-grade and says the tub can also stay set up permanently. That is close to everything the listing documents: there is no chiller in the price, and we could not find a published capacity, size, temperature or warranty for this model on the vendor's site, which is why it scores lowest on quality. Without a chiller you fill it with cold water and ice, so running costs depend on how often you plunge. Dynamic Cold Therapy also sells a $2,999 cedar Barrel Plunge and a $6,499 stainless Cuboid if you want something sturdier from the same brand. Treat this as a low-cost way to try the habit.
