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 67.0 cubic feet, or 2.48 yards.

Don’t forget the cove

Most vinyl-liner pools use a sand cove: a sloped ridge of sand around the inside of the wall that keeps the liner from slipping under the wall. Add about 10 to 20 percent more sand for the cove, depending on the manufacturer’s spec.

Level the ground first

The sand layer is a cushion, not a fix for uneven ground. Level the site by digging down the high side rather than filling the low side, and compact it. Pools need to be very close to level; a tilt shows plainly in the waterline.

Which sand

Mason sand is the usual choice: fine, clean and free of rocks. Concrete sand is coarser. A ground cloth or foam floor pad over the sand adds liner protection.

Common mistakes

Underestimating depth and forgetting extra for settling and spreading are common. So is laying sand straight on sod, which lets grass and weeds come through. Clear and level the ground first.

Keeping it in place

Sand moves with wind, rain and use. A frame, edging or a cover keeps it where you put it. Where sand meets lawn, a border of pavers or timber stops it from spreading into the grass and makes mowing easier.

Topping up later

Sand compacts and spreads over time, so expect to add a little each year. Keeping one or two spare bags on hand makes touch-ups easy, and buying the same type keeps the texture consistent.
