Detailed Overview

How It Works

The Frozen 4 XL Cold Plunge cools water down to a near-freezing 37°F, triggering a “shock” response in your body. This response causes blood vessels to constrict, sending blood and oxygen to vital organs. As you leave the water, your vessels re-expand, delivering a surge of oxygen and nutrients throughout your body. The result? Improved circulation, accelerated recovery, and an invigorating burst of energy.

Who It’s For

This XL cold plunge is ideal for tall or heavier athletes, dedicated fitness enthusiasts, sports rehab facilities, and anyone seeking an advanced recovery method. If your home workout or exercise routine demands rapid muscle relief, deeper stress reduction, or a boost in circulation, the Frozen 4 XL is designed for you.

Why It’s Great

Developed by doctors and endorsed by medical professionals like Dr. Aaron Cypess and Andrew Huberman, the Frozen series stands out for its focus on safety, durability, and efficiency. With FoamSeal™ Insulation, a 20 Ultra Micron Filter System™, UV-protected exterior, and the convenience of No Plumbing Needed, it’s a premium solution that can be placed virtually anywhere. You get all the benefits of professional cold therapy in a single, streamlined system.
