At Hydro Spa® you get the latest developments in the industry. Our exclusive Poseidonite™ Reinforced Hot Tub Shell technology has been developed through years of product testing. The Hot Tub shell is the single most important item to consider when you purchase a spa. If your hot tub shell develops a crack or a leak it may be very hard or impossible to fix it. Therefore, choosing a shell that is made of the best components and manufactured under strict quality control is of the utmost importance. We are so confident in the performance of our hot tub shell that we offer a lifetime warranty against leakage to the original consumer for as long as you own your spa.

        Here is how we do it.

We start with genuine, first quality, continuous cast acrylic and vacuum form it into our ergonomically designed molds. The cross linking technology of the acrylic allows us to provide you with intricate patterns that are contoured to fit all the spa users with the utmost in comfort. We then add layer-by-layer of hand rolled fiberglass to the back of the hot tub shell to provide greater structural strength. Our proprietary bonding agents virtually eliminate the potential for de-lamination. The finished shell is now ready for the insertion of our high water volume jets.
