Location Selection

Choose a sunny, easily accessible spot for your sandbox where you can monitor children from a window. Consider placing it partially below ground for easier access and added fun. Before digging, check utility lines for safety. Ensure good drainage to avoid puddles. This preparation guarantees enjoyable playtime for years to come.

Pro tips:

  • Visit 811.com to get underground utility lines marked before digging
  • Select a location viewable from at least one window
  • Opt for a spot with easy-to-dig soil if setting the sandbox partially in-ground

Box Construction

Use 2×12 pressure-treated lumber to build a square sandbox frame. Measure diagonally to ensure right angles and join corners with 3-1/2-inch plated deck screws. Add seating boards by cutting four lengths of 2×6, two at 76 inches and two at 65 inches. Attach these to the top edges of your frame with about two inches of overhang on both sides. Space screws evenly to prevent splitting.

Materials needed:

  • 2×12 pressure-treated lumber (4 pieces)
  • 2×6 pressure-treated lumber (4 pieces)
  • 3-1/2-inch plated deck screws
  • Drill or impact driver
  • Measuring tape
  • Framing square

Installing Cover and Seal

Create a hinged wooden cover using exterior-grade plywood cut to fit snugly over the top, leaving a 1/4-inch gap for ventilation. Install four solid brass butt hinges about eight inches from each corner using exterior-grade screws. Attach the cover to the sandbox frame, ensuring it's flush with the seat boards. Install outdoor utility handles a foot from the bottom on each side for easy lifting.

This lid protects your sandbox from rain, debris, and animals while providing additional seating when open.

For added protection and longevity:

  1. Apply wood cleaner before staining
  2. Use a semi-transparent waterproofing stain and sealer on all surfaces
  3. Allow wood to dry fully in the sun for a day before applying stain
