Elegant style combined with a strong steel wall makes the Trinity the finest above-ground 52-in deep pool on the market today. Designed by one of the world’s leading pool manufacturers, this pool features their thickest (.46-mm) galvanized steel wall for ultimate durability. With all resin components, the Trinity is a notable improvement on the traditional pool with steel components. UV inhibitors embedded in the resin provide additional protection against the elements. From the injection-molded top rails and seat caps to the multiple layers of protective wall coating, including an alloy of zinc and aluminum, this pool is designed for rugged durability and many years of family fun. Trinity oval pools feature a buttress-free design. This advanced engineered design eliminates the unsightly diagonal braces that many oval pools need on the sides for structural integrity. Not only does the pool look better, but you can locate these pools in narrow areas when you eliminate the clearance needed for the braces. Comes standard with a wide-mouth skimmer, return fitting, and step-by-step instructions for quick and hassle-free installation. Liner not included. Backed by a 30-year limited warranty. Available with a 52-in wall in a variety of oval sizes to fit your backyard.
