In the cold plunge vs ice bath debate, the water does the same job: the difference is how it gets cold. An ice bath is a tub you fill and cool with ice, while a cold plunge tub has a chiller and filter that keep the water cold and clean every day.

Which should you choose?
Start with a simple ice bath if you are new to cold water. In an Irish winter, water from the tap is often cold enough without ice. However, if you want to plunge every day, especially in summer, a chilled cold plunge tub saves buying ice and keeps the water clean.
Safety first
Cold water shock is real, so get in slowly, keep sessions short and never plunge alone. The RNLI explains cold water shock clearly. For timings, read how cold should an ice bath be.
