Keep your water at the perfect temperature for longer with the ColdForge PU Foam Insulation. Designed specifically for the 2 person oval fiberglass tub, this polyurethane foam wrap is one of the most effective upgrades you can add to your cold therapy setup. By insulating the exterior of your tub, the foam retains cold temperatures between sessions — meaning your chiller works less, your energy bills stay lower, and your water stays colder for longer. It also adds structural support to the tub shell, extending its lifespan significantly. If you're serious about cold therapy, this is not optional — it's essential.
