Power Steel 14' x 48"/4.27m x 1.22m Pool Set - Water Capacity (90%): 15,232 L (4,024 gal.) The round shape of the pool provides for easy installation, enhanced stability, and less wasted space due to the fact that the pool doesnt require lateral support. The extra strong side walls of this pool are constructed with Tritech, a 3 layer reinforced material with a polyester mesh core encased between two layers of high gauge PVC material. This creates a total thickness of 0.40-0.80mm (16-32 gauge) depending on the size of the pool, offering superior strength and durability
