Thanks to the brilliant innovation of DURA-SHIELD,™ Strong Spas’ HardCover is the best in its class for durability. DURA-SHIELD uses patented technology to create a true HardCover molded hollow from durable resin, then filled with proprietary foam to protect against harsh environments and provide energy-saving heat retention. Our UltraStrong CoverLIfter operates pretty much like opening a car door, except on a spa. Our HardCovers do the heavy lifting so you don’t have to.

Combining resilience with security and strength with beauty, DURA-SHIELD requires very little maintenance and is built to last.
