Cove Spas offer high volume circular flow, which is the superior form of hydrotherapy, and it’s perfected in their round tubs! Cove Spas give you superior whirlpool therapy. Simple and affordable, they don’t have all the “bells and whistles” that some tubs depend on, but Cove does have a lifetime warranty on their durable poly shells. They offer value without sacrificing quality. Reliability is crucial. Every fitting is clamped and glued and the components used are found in tubs that are two or three times the price. And every tub is water tested twice to assure that reliability is second to none!
