Our foam injection system and Mylovac™ design makes the Castcore hot tub cover highly resistant to water saturation, significantly prolonging the life of the cover. The covers of your hot tub extends down to the rim of the cabinet, which guarantees total insulation at the top of the spa, preventing heat loss and safeguarding against the build-up of snow and rainwater.

When not in use, the hot tub cover can be secured to the spa with lockable straps. This prevents any small children entering the spa unsupervised and guards against harsh weather conditions and high winds.
