Simply Built Different

  • Superior Insulation

    Heat rises, cold falls. It's simple science. Our patent-pending tapered plunge design is the first to take this into account, locking in the cold by putting more insulation in the base. This means it gets colder, faster, with less energy, and it stays colder than any other plunge on the market.

  • Patent-pending NipTide Vortex

    Static water warms around your body to create a thermal barrier — that’s why we made our plunge with a shape that creates our patent-pending active vortex current when paired with the recommended pump and fittings so you experience true, uninterrupted cold therapy from start to finish.

  • Safety First Design

    From a child-safe locking lid to rock-solid rotomolded construction, every detail is engineered with your family’s safety at the forefront. Recovery should be refreshing — and worry-free.

Engineered to Stay Cold

We took advantage of science to maximize performance. Our patent-pending design packs more insulation where it matters most— the base — locking in the cold and reducing heat loss. It cools faster, uses less energy, and stays colder longer than anything else out there.

Cleaner Water. Longer Life. Less Hassle.

By separating the chiller from the filter, each component does its job more efficiently. Continuous filtration keeps your water crystal clear without overworking the chiller. This means fewer replacements, much lower replacement costs, less maintenance, and consistent cold you can trust.

The Thermal Layer

Your body will naturally warm the water around it, even in an ice bath. That warm layer makes the plunge easier, but less effective. For those who want to, breaking up that barrier keeps the cold honest and keeps your nervous system engaged, which is where the real physical and mental benefits happen. Our patent-pending vortex flow system actively breaks that thermal barrier for a colder, more effective immersion.
