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
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.
Topping up later
After a season of use, the level usually drops an inch or more. A few bags of the same sand restore it; rake the old sand loose first so the new layer blends in.
Keeping it in place
Plan for some loss each season from splashing, digging and rain. A sturdy border, a fitted cover and fabric underneath keep the sand clean and contained, so you top it up less often.
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.
