HydroBarrel® 350 - Ice Bath Barrel

The HydroBarrel® 350 is designed for buyers who want a more solid and long-lasting cold plunge setup without moving into a large commercial-style unit. Built for both indoor and outdoor use, it combines a durable hard-shell construction with a compact upright barrel format that supports deep immersion while taking up relatively little space.

Its shape is designed to let users plunge while remaining upright and relaxed, making it a strong option for regular cold therapy, recovery routines, and everyday wellness use. The 350 litre capacity also helps reduce water usage compared with larger traditional cold plunge setups, which can make it more practical for repeated use.

A major feature of this model is its improved chiller compatibility. The HydroBarrel® 350 is built with two lower 25mm brass threaded outlets and one upper 25mm non-threaded inlet hole, allowing connection to chillers with hoses up to 25mm internal diameter. This gives buyers flexibility to use it as a simple manually filled plunge or connect a chiller for more controlled temperature management.

Built from UV-resistant LLDPE, the barrel is positioned as a durable, non-toxic, BPA-free, medical-grade option with a non-porous surface that resists the absorption of oils, toxins, and contaminants. Combined with its wood-effect exterior, included lid, drainage hardware, and optional step and seat upgrades, the HydroBarrel® 350 is a strong choice for buyers who want a sturdy, good-looking, and low-maintenance plunge barrel.
