The Intex Ultra XTR 18′ x 52″ Round Above Ground Pool Set represents a pinnacle in residential, heavy-duty backyard aquatic engineering. Designed for homeowners demanding an uncompromised combination of massive swimming volume and long-term chassis durability, this high-capacity seasonal resort system measures 18 feet in diameter with a deep 52-inch sidewall. At an optimal 90% fill rate, this heavy-duty round frame installation holds an immense 6,981 gallons (26,423 L) of water—yielding a spacious, high-stability private swimming area that accommodates large groups effortlessly, completely eliminating the need for expensive yard trenching or permanent concrete installation.

Structural longevity is achieved via Intex’s proprietary, ultra-dense super-tough 3-ply PVC liner matrix, which embeds a high-tensile polyester mesh core between two thick layers of specialized, puncture-resistant polymer. To add a premium look to its rugged architecture, the inner lining is supported by a uniquely designed frame of galvanized steel treated with a rust-resistant inner and outer powder coating and a UV inhibitor. This heavily fortified skeleton utilizes an advanced Easy Lock System with engineered T-Joints, a precision locking technology that seamlessly aligns the frame poles without tools, preventing metal-on-metal friction and guaranteeing flawless structural rigidity during high-activity usage.

Key Features:

• Super-Tough 3-Ply PVC Liner: Engineered with puncture-resistant, heavy-gauge material fortified to survive intense summer UV exposure, heavy family use, and continuous hydrostatic pressure.

• Dual-Coated Galvanized Steel Frame: Built with premium heavy-gauge metal tubing coated internally and externally to prevent rust, scaling, and oxidation from continuous moisture exposure.
