The Largest Stainless Steel Cold Plunge in Our Lineup
If you want a real stainless steel cold plunge with room to stretch out and a finish built to last, the CUBOID XL is the flagship of the Dynamic Cold Therapy line. A nano-coated stainless steel cabinet with Pacific Cedar trim gives you a durable, weather-resistant exterior, while the 304 stainless steel interior brings a premium, easy-to-clean surface. It arrives ready to fill, no assembly or inflation involved.
How Does the CUBOID XL Actually Work
This tub uses a rigid nano-coated stainless steel cabinet, built to hold its shape and resist the elements without ever needing to be pumped up. The included Pacific Cedar step makes entry and exit easy.
The tub itself does not cool the water. Temperature comes from ice, manual water changes, or the optional chiller add-on.
This Tub Uses a Different Chiller Than Our Barrel Tubs
Important: this tub is only compatible with the Premier Edition chillers (.8 HP or 1.0 HP), not the Pro chillers used on our Barrel cold plunge tubs. If you already own a Pro chiller from another Dynamic Cold Therapy tub, it will not work with this one. The Premier Edition chillers cool automatically down to 37°F, with WiFi app control for temperature and scheduling, and are purchased separately.
What Results Can You Actually Expect
Regular cold water immersion is commonly used to help ease muscle soreness after training, support circulation, and give you a sharp, alert reset. Results vary by person and by how consistently it's used. This product is not meant to diagnose, treat, cure, or prevent any medical condition.
