We wanted to share a fun project for the summer months. Not all home repair and DIY projects have to be serious.

Today we will provide instructions on how to build a DIY sandbox for your children or grandchildren to play in at your home.

  • Power Circular Saw
  • Claw Hammer
  • Power Drill
  • Digging Shovel
  • Square & Level
  • Dust Mask
  • Caulk & Caulk Gun
  • Protective Eyewear
  • Mason’s Line
  • Hearing Protection
  • 8 1x6x8 Cedar Boards
  • 4 1x3x8 Cedar Boards
  • 1-1/4 in. Galvanized Screws
  • Sand

The first thing you need to do is decide where you want the sandbox. The total size of the sandbox will be 64 square feet. You need somewhere in your yard that can accommodate the entire size of the sandbox and you need to decide if you want the sandbox in direct sunlight or in shade.

Plan the layout of the sandbox using twine and garden stakes to create straight lines for the outline of the sandbox. You will then need a digging shovel to cut out the shape. Learn more about all of the types of shovels.

Dig out all of the loose soil and dump it into a wheelbarrow. You can use the soil for a garden bed or dispose of it later. You want to dig so the bottom of the sandbox is just below the surface level of the yard.

Lay landscape fabric in the opening to prevent grass and weeds from growing up through the bottom of the sandbox.

Now cut the 1×6 boards to 8 ft. lengths. You need to clamp two of the boards on top of each other four different times. This will create 1-ft. of total depth for the sandbox. You also need to cut eight different 10-in. pieces to create the inside support pieces. You will then screw these into each corner with your power drill and galvanized screws.

Now pour the sand into the sandbox. You need enough sand for a 64-square feet area. Leave a little room for the children to move around and for toys too. You should replace the sand each year.

You also might want to purchase a tarp to leave on top of the sandbox when it isn’t being played in. This will protect the sand and the wood from harsh weather.
