DIY Kids Wooden Sandbox
A simple square sandbox from four boards and four short corner posts. Add a lid so it stays clean and dry. It's a one-weekend build, and kids can help with sanding and filling.
- Time One weekend
- Skill Moderate, needs a drill
Before you start. Pick the spot first. Part shade keeps the sand from getting too hot in summer, and a spot you can see from the kitchen window makes it easier to keep an eye on play. Ask the lumber yard to cut the boards to length if you don't have a saw; many will do it for free or a small fee. Use untreated wood for anything kids sit in.
What you'll need
- Four 2x10 boards cut to 4 feet (cedar or redwood resist rot)
- Four 4x4 corner posts, 10 inches long
- 3 inch exterior screws and a drill
- Sandpaper
- Landscape fabric
- Bagged play sand
- A plywood lid or a fitted tarp
How to make it
- Build the box. Screw each board to the corner posts with two screws per board end.
- Sand. Sand every edge and corner smooth, since small hands will grab them.
- Prep the ground. Level a spot and lay landscape fabric down so sand stays in and weeds stay out.
- Fill. Set the box on the fabric and fill it with play sand to a few inches below the top.
- Cover it. Keep the lid on when it isn't in use, to keep out rain and animals.
Make it your own
- Paint the outside in a bright color with outdoor paint.
- Add a canopy or an umbrella for shade on hot days.
- Build a smaller box on legs for toddlers, at table height.
Care and storage. Rake the sand now and then, and let it dry in the sun with the lid off on a dry day. Top it up with fresh play sand each spring.
