Product Features of the 4x4 Composite Sandbox
  • Each 4 ft. 2” Profile composite board is made by recycling the same amount of plastic as 97 single-use bottles.
  • The food-safe composite boards are made from 38% HDPE plastic and 62% wood fibers that come from certified, sustainable sources.
  • The boards have a snap-lock system, so you can just slide them into place and snap them together.
  • The sandbox comes with a limited lifetime warranty if you register it, or a 5-year warranty without registration.
  • The canopy or cover comes with a 1-year warranty.
  • The strong composite material can handle mowers and string trimmers without getting damaged.
  • Frame It All’s modular system lets you design your sandbox in many different ways. You can add to it or change it using the same or extra One Inch Series Frame It All pieces and accessories.
  • You can make your sandbox design unique using the 270-degree pivoting bracket.
  • The composite boards are made to last and need very little care. Unlike cedar, they will not rot, splinter, or fall apart. They are also resistant to bugs and termites.
  • The canopy can also be used as a cover.
  • The UV-ray resistant polyester cover helps keep your children safe from the sun.
  • You will need 13.5 cubic feet of sand to fill the sandbox to 11 inches deep, or 6.75 cubic feet for a 5.5-inch depth.

    Why Choose a 4x4 Composite Sandbox for Outdoor Play

    Want your kids to spend more time outside? A 4x4 composite sandbox creates a safe, fun, and imaginative play space right in your yard. It gives children a special place to dig, build, and explore while enjoying fresh air and sunshine.

    Perfect for small spaces

    With a 16 sq. ft. footprint, this sandbox fits neatly in smaller yards or patios without taking up too much space. Its square shape makes it easy to place and keeps your yard looking tidy.

    Safe for children

    Made from food-grade HDPE recycled plastic and sustainably sourced wood fibers, the boards are free from splinters and harmful chemicals. You can feel confident that your children are playing in a healthy, safe environment.

    Easy to assemble

    Our patented snap-lock brackets slide easily onto each board and lock securely. Unlike traditional wooden sandboxes that can splinter or need a lot of work, this system is stress-free and kid-friendly. You can put it together in a single afternoon with just a hammer or mallet.

    Low maintenance

    Cleaning is simple. Just wipe the boards or spray them down when needed. The durable composite boards resist rot, splintering, and bug damage, so your sandbox will stay looking great year after year.

    Eco-friendly materials

    By using recycled plastic and sustainably sourced wood fibers, this sandbox supports environmentally responsible play. It’s a choice that’s safe for kids and kind to the planet.

    Fun and versatile

    The square design allows your child to explore, dig, and build in a well-organized space. The included cover keeps sand clean and protected when not in use, and the neutral color options make it easy to blend with your yard or garden.

    Made From Durable Material That Will Last

    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. We love products that can be reused and recycled for other purposes. And how sweet would it be to have your little one's childhood sandbox going strong years later filled with their favorite flower?

    Add a Canopy or Cover

    The Telescoping Square Sandbox Canopy can quickly turn into a cover with just a few simple lever flips. When used as a canopy, it gives your child cool shade and protects their skin from the sun’s harmful UV rays. It also keeps rain, leaves, and dirt out of the sandbox, and stops neighborhood cats or other animals from using it as a litter box.

    The domed shape keeps water from pooling on top. This helps stop mosquitoes from breeding in the sandbox. The 48 in. x 48 in. x 37 in. square canopy and cover fits perfectly with any 4 ft. x 4 ft. Frame It All sandbox. The telescoping poles slide into the corner joints, and the canopy can fold down for easy storage when you don’t need it.

    You can use the canopy and cover not just for sandboxes, but also for play areas or garden beds. It’s a simple way to make your yard safer and more fun for your kids.
