Key Details
52 Inches Is the Depth That Matters
Depth determines whether an above ground pool is a splash pool or a swimming pool. The Intex Ultra XTR at 52 inches is chest-deep on a 5'10" adult -- you can actually swim, tread water, float, and do underwater activities. That extra depth is what separates it from the 30-inch and 42-inch pools in this comparison.
At 18 feet across, the Ultra XTR also provides enough room for multiple adults to use the pool simultaneously without constantly bumping into each other. The combination of depth and diameter makes this the closest above ground option to the in-ground pool experience most buyers are trying to replicate at a fraction of the cost.
Sand Filter vs. Cartridge -- Why It Matters at This Size
The included 2100 GPH sand filter pump is a meaningful advantage over cartridge-based systems. Sand filters trap finer particles than cartridge filters and clean through a backwash cycle rather than requiring you to buy replacement cartridges every few weeks. For a pool holding thousands of gallons and running through a full summer season, the sand filter keeps the water cleaner with less ongoing cost and maintenance effort.
Setup for a pool this size is a multi-hour commitment. The SuperTough liner, Prism frame assembly, and filtration plumbing all take time. Intex provides detailed instructions, and the process is manageable for two adults in an afternoon. Plan to run the filter for 24 hours before swimming to circulate the initial fill.
