Strong Spas is a global leader in the spa industry and one of the largest spa manufacturers in the world. Every affordable luxury spa is proudly custom-built in one of our facilities in Pennsylvania. Strong Spas is the innovator of the DURA-SHIELD™, which is the first true patented, hardcover system that is molded hollow from durable resin and filled with a proprietary foam to protect the spa from harsh environments and provide energy-saving heat retention.
This hardcover system features the first integrated ULTRASTRONG™ CoverLift system for safe, easy open-and-close performance. While other spa companies continue to sell soft covers that rot, mold and have to be replaced every two to three years, the DURA-SHIELD hardcover system is the only one on the market that is backed by a lifetime warranty.
