With just some basic home improvement knowledge, you can build a pallet sandbox like this with colorful stripes, benches for sitting, holes to trickle sand through, a beach umbrella stand and lots and lots of sand.
Use a saw to cut four board lengths to serve as the sandbox sides; two at 7’ lengths and two at 6’. Simply butt the ends together to create a rectangle and secure with either nails or screws.
If you are adding a floor, cut pieces to size and nail or screw them into the bottom of the frame, making certain it remains square.
Use the leftover pieces of wood and mark and measure the dimensions. Cut the angled pieces with a saw, sand if necessary, and secure to the frame. You can drill holes in the benches for water run-off and as an added play feature.
Before painting the sandbox, elevate it off the ground for a clean paint job. Use a primer and paint the inside and outside with a durable, weather-resistant paint, like Behr Ultra exterior in satin or gloss finish.
Find an appropriate location for your sandbox. Depending on your lawn, you might want to consider removing the grass underneath to provide a more level surface.
Fill with sand (20-30 bags of play sand) and let the kids enjoy their new backyard addition.
