Footprint math

The oval is a rectangle with a half circle at each end: width × straight section, plus a full circle with the pool’s width as its diameter. At 2 inches (0.167 ft) the volume is 42.8 cubic feet, or 1.59 yards.

Don’t forget the cove

Many installers build a cove of sand or pre-formed foam along the base of the wall. If you use sand, plan on extra material beyond the flat base.

Level the ground first

Dig to level soil rather than building up low spots with sand, which can wash out. Compact the ground, then spread and smooth the sand. Follow your pool manufacturer’s base instructions, since some specify pads or a different base.

Which sand

Masonry or mason sand is fine-grained and smooth under a liner. Avoid sand with sharp stones. Some owners add a foam or felt pad on top of the sand to protect the liner.

Bags vs bulk

A 50 lb bag holds about half a cubic foot, so a single cubic yard is roughly 54 bags. For anything larger than a small box, a bulk delivery or a pickup load from a supplier saves money and trips.

Measuring the area

Measure the footprint in feet, multiply for square feet, then multiply by the depth in feet. Divide cubic feet by 27 for cubic yards. Round shapes use 3.1416 times the radius squared. Measure twice; a small mistake in diameter changes the total more than you might expect.

Common mistakes

Using the wrong sand type is the big one: sharp concrete sand or sand with pebbles is uncomfortable and can damage liners. Another is skipping the ground prep, expecting sand to hide bumps and slopes. It does not; it shifts and washes out.
