As one of the largest spa manufacturers in the world, Strong is known for its innovative design and engineering of spas built to last a lifetime. We are known for delivering the most durable and reliable spas on the market that are easy to operate and withstand the harshest climates. To achieve this, we are committed to quality control and a state-of-the-art manufacturing process. 

Cabinet Production

Strong Spas are made in the USA at our Pennsylvania facility.

The cabinet process begins with a hollow, two-part mold, which is filled with granular polyethylene polymer. The mold is mounted to a sophisticated machine, which externally heats while biaxially rotating the mold. The heat softens the powder into liquid form. As the mold rotates, the melted material coats the inside of the mold. Intelligent software distributes the material evenly to ensure consistency of product. Once cooled, the two-part mold is opened, revealing the finished resin component.

All-Weather Construction

Strong Spas are uniquely insulated to save energy and maintain water temperature so they can be enjoyed year-round. Our patented, virtually indestructible DURA-LAST resin cabinet is designed to withstand the harshest of climates and is backed by a Lifetime Warranty!
