Questions We Get a Lot About Cold Plunges
A portable ice bath tub, like our XXL Drop Stitch Ice Bath Tub, is a flexible, easy-to-set-up option that you fill manually with cold water and ice — ideal for those starting their cold therapy journey or looking for a budget-conscious entry point. A cold plunge system with a built-in chiller, such as our 1/3HP Ice Bath Chiller and Tub Bundle or the WOODBRIDGE system, actively circulates and cools water to your target temperature without relying on ice. If you want consistent, repeatable cold therapy sessions with minimal prep, a chiller-equipped system is worth considering.
Cooling times and target temperatures vary by system and ambient conditions, so we always recommend reviewing the specifications listed on each product page for the most accurate guidance. Our chiller-equipped options, including the WOODBRIDGE 1.3HP system with rapid cooling technology, are designed to reach cold therapy temperatures efficiently and maintain them throughout your session. Starting at a temperature that feels manageable and gradually reducing it over time is a common approach many cold therapy users find effective.
Yes, the WOODBRIDGE 54-inch Indoor Cold Plunge Tub is specifically designed for home use and features an insulated tub cover, ozone sanitation, a filter circulation system, and Wi-Fi-enabled APP and remote control — making it a premium, low-maintenance option for a dedicated home wellness space. Its self-contained design means no need for external plumbing beyond a standard water source, and the ozone sanitation system helps keep the water clean between sessions. It is built to complement a modern, spa-inspired home environment.
We offer Free Shipping on Most Orders Within the Continental U.S. (Excludes AK/HI), so most customers in the contiguous states receive their cold plunge tub without additional shipping costs.
