Fill depth
Fill a sandbox about 2 to 4 inches below the rim so sand stays in during play. Most kids are happy with 8 to 12 inches of sand.
Choosing the sand
Bagged play sand is washed and screened. For big boxes, bulk washed sand can cost less; make sure it is clean and soft, not a coarse concrete sand.

Cover and drainage
Lay fabric under the sand for drainage and weed control, and cover the box when not in use.
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.
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.
Bags vs bulk
Bagged sand is convenient for small jobs and easy to carry in a car. Once you pass about half a cubic yard, bulk sand from a landscape supplier usually costs much less. Ask whether the bulk sand is washed and screened.
