Why This Tub?

The round upright design puts your entire body in the water — not just your legs. At 36" diameter and 34" tall, it’s built for full immersion up to the shoulders for athletes up to 6 ft. The 7-layer PVC construction with EPE foam insulation holds your target temperature for up to 4 hours, and the 1/2" threaded inlet and outlet mean you can connect a water chiller for automated temperature control whenever you’re ready. Inflates in 2.5 minutes, packs into a backpack, and goes wherever your training does.
