Most cold plunge tubs are designed to maintain water somewhere between 4°C and 15°C (39°F–59°F), and many users start toward the warmer end of that range before gradually working colder over time. The right temperature is personal — it depends on your tolerance, your routine, and how long you intend to stay in. Our units are built to hold a consistent temperature so you get a reliable experience every session.

Many of our cold plunge units are built with weather-resistant materials and insulated construction, making them well-suited for outdoor placement in most climates. That said, if you're in a region with extreme freezing conditions, it's worth reviewing the specific unit's operating range before installing it outside permanently. Pairing your plunge with a covered outdoor space, like a pergola, can also help protect the unit and make the ritual more enjoyable in variable weather.

Units equipped with a built-in filtration and circulation system can maintain clean water for weeks at a time with the right care — typically a combination of regular filtration cycles and appropriate water treatment. Tubs without filtration will require more frequent water changes, often every few days depending on usage frequency. Always refer to the care guidelines included with your specific unit for the recommended maintenance schedule.

We offer free shipping on most orders within the Continental U.S. (excludes AK/HI), and cold plunge tubs are covered under our 30-day return policy. Because these are large, heavy units, we recommend reviewing our full Return Policy for details on how returns are processed for oversized items before completing your purchase.
