Want the kids to spend more time outdoors? Create an outdoor destination for them to get outside, explore their imagination and goof around! This simple project can be completed in a weekend with no tools required. (other than a hammer or mallet) Create a space that’s just for kids with this 16 sq.ft. square sandbox kit. Keep it safe and tidy with the included sandbox cover. The extra-deep sandbox makes digging more fun and the compact square shape makes it great for small spaces.

Our patented snap-lock brackets simply slide onto each end of a board and fasten securely with snap-lock buttons. Unlike wooden sandboxes that splinter (and are labor intensive), Frame It All boards and brackets go together with ease. Our composite sandboxes are made from sustainably sourced wood fibers and food-grade HDPE recycled plastic, so your children are safe from splinters and hazardous chemicals. Easy to maintain - simply wipe or spray clean when necessary. And unlike cheap plastic sandboxes, your Frame It All sandbox won't stand out like a sore thumb on your landscape.

Our materials are so durable, your sandbox will still look great by the time the kids have outgrown it. The modular design of our product makes it easy to repurpose your sandbox as a raised garden bed or landscape edging later on.

The domed construction prevents water pooling which can help prevent a mosquito breeding ground. The 4x4' square cover integrates with any 4'x4' square Frame It All sandbox.
