Thermal Foam Spa Blanket.

Happy with the cover, it has assisted in keeping the water at temperature during very cold nights; long term hoping that it saves the inside of the cover from degradation from the off gassing of chemicals. The only negative is that they dont come pre-cut templated for common models such as the Master Spa15D; I am not much at the arts and crafts of cutting to fit and would have paid a premium for a templated pre-cut cover..

Extremely easy to use…cut it to the perfect shape in a few minutes. Increased efficiency with our tub!
