Children love to play in the sand, and you can make a custom sand pit for your child. Doing so allows you to control the kind of sand the children play with and ensure that it is free of bacteria or harmful chemicals. You can customise the sand pit by painting it a bright colour or writing your child's name on it. Make a cover for the sand pit to prevent it from getting wet in the rain or being used as a litter box by neighbourhood cats.
Find a good, shady place for your sand pit. Measure the desired dimensions of the sand pit and place pegs in each corner. Tie string to each peg to mark the perimeter.
Use the edging tool and shovel to remove the lawn to a depth of about 5 cm (2 inches). Level the bottom of the pit area. Hammer in the decking posts until they protrude by only the width of two of the decking boards.
Measure the exact length of the sand pit sides. Use the saw to cut the decking boards to size. Drill holes into the decking boards and screw them to the decking posts so that they meet at right angles.
Fill the pit with half a bag of sand. Use the shovel to make it level. Place the liner on the bottom of the sand pit. Fill the liner with sand, then trim the edges to size, leaving an overhang of 5 cm (2 inches). Turn the edge of the pond liner over and nail it to the edge of the sand pit.
Measure 4 90-degree triangles from the plywood sheet. The two short sides of each triangle should measure 3.5 cm (1 3/8 inch) each. Cut out the four triangles, drill holes and screw them into the corners of the sand pit as seats.
Use sand paper to remove splinters from the wooden frame. Treat the wood with stain or paint as desired.
Make a plywood sheet cover or use a tarp to cover the sand pit when it is not in use.
Ensure that screws are driven all the way in and that splinters have been removed.
