How to Make an Easy DIY Non-Toxic Sandbox

5 Step Bug-Resistant DIY Sandbox

This Christmas my sister’s family came to visit. Her oldest and my son are just about one year apart and are best buddies. Their absolute favorite thing to do, hands down, is to run. In fact, “running” was my son’s New Year’s eve resolution. This was a resolution that was decidedly not broken, unless we adults did something about it. And while running is certainly fun, there is a point when we all need a break from the sound of shrieks and bare feet smacking on the floor.

How to Make an Easy DIY Non-toxic Sandbox
Because they are both high energy, the one thing that occupies them (other than running!) is doing something with their hands. Tinker toys and play-dough got some good use, but the sandbox was a huge hit! One afternoon, they played together uninterrupted for two hours by themselves! My sister and I were careful not to disturb the hole digging scenario that was happening and we were able to kick back and have a good sister-to-sister talk.

I was so thankful we built that sandbox last Spring! When we bought our house, the home inspector had advised us to put in a french drain on one of our gutters which had been draining right by the foundation. We combined the two projects and created our sandbox/flowerbox.

How to Make an Easy DIY Non-toxic Sandbox

Step One: Prep the area

We have our sandbox next to the house because of the shape and size of our yard and also because that is where we needed to lay the french drain. We dug down as far as we needed for the drain, which was about 4 inches. Depending on your soil, this is the hardest part! We have hard red clay. My hubby had the idea to layer the bottom with pea gravel (which is really cheap at your lawn store).

This has two benefits — first, it helps the sandbox drain and remain mold-free (even over clay soil) and second, it keeps ants from building colonies directly under the box — or any other burrowing bugs or critters.

Step Two: Prep the wood

You have a few choices here. You can buy pretreated wood from your hardware store, you can use cedar or any other naturally rot and termite resistant wood or you can buy untreated wood and seal it yourself. In our area, cedar is expensive and was not in our budget, but I do think it is the best choice for a non-toxic wood. If you live on the West coast, this or a redwood might be a relatively affordable option for you.

Chemically treated wood can be unsafe for children and was banned for use for play equipment in 2003. So the cheapest option for us was to buy untreated wood and seal it ourselves.

We used something similar to this, ECO-SAFE Wood Treatment – Stain & Preservative by Tall Earth – 1/3/5 Gallon Sizes – Non-Toxic/ VOC Free/ Natural Source (1 Gallon). It comes as a powder which you mix with water and then brush onto the wood. One package was enough for both our sandbox and a garden box we made.

This kind of wood treatment is safe both for kids and for gardens and will help provide resistance to pests, although it is not specifically termite resistant.

Step Three: Build the Box!

This is the easiest part! We bought four 6-foot pieces of lumber sized 2X10 inches. If you have a younger child, you may consider an 8-inch or even 6-inch high board as it will be easier for them to step in and out of the box.

We screwed the boards together in a square. Then we stapled on window screen fabric (which came on a roll) to the bottom of the box. This would separate the sand from the gravel while letting rain water through and create another deterrent for pests as well as allowing the sandbox to drain as opposed to covering it and letting mold or toxins build up. A year later I am happy to say the screen is intact — which not the case when we used landscape fabric in a smaller sandbox at our old house.

Step Four: Build the Bench and Flower Box

Both of these are optional. You could get the same effect from planting flowers in the ground right next to the sandbox or in pots. We did the flower box to accommodate the french drain — and I love how it looks.

We planted lemon thyme and french marigolds, both of which are known to repel insects and snakes. In the summer, I pick some of the thyme and crush it in my hands and drop in is the corners of the box. The spiders run in the other direction and will not cross the thyme. I also rub it on myself and my son. My son also loves watering his sandbox garden.

How to: Flowerbox

The flowerbox is one 6-foot piece of 2×6 lumber and two 6-inch pieces of 2X6 lumber. We created the frame and then screwed it into the sandbox. Add dirt and flowers and you’re done!

How to: Bench

The bench is great as well– especially if your kids want you to join in the play! That way you can sit with your feet in the sand, but you don’t have to sit in the and itself. Unlike the benches that become lids, this is a larger bench that an adult can actually sit on.

The first step is to cut the angled pieces for the backrest. As you can see in this picture, we used an angled pieces of 2X4 lumber for proper support.

The seat was one piece of 2×12 lumber. The 12-inch depth makes it comfortable for an adult to sit on. We cut the seat so it inserted into the backrest supports and finished it with four pieces of 1×3 lumber to create the back of the seat.

Step 5: Fill the box add Toys, Shade, and Organization

As you add the sand you can add in cinnamon as a further repellent to ants. We actually never did this, although I meant too. The ants have stayed away anyway, even though I see them on the patio all the time. I think the pea-gravel is a great deterrent.

We added two garden trellises with hooks for shovels and buckets. We also added an outside planter for more places to store toys — an idea we got from Happy Hooligans. Click over for more great ideas for sandbox play and organization!

For shade, we affixed a bit of PVC pipe to the side of the box and an umbrella. The umbrella tilts for maximum shade — important for our summer mornings.

We actually do not have a cover on our sandbox which keeps the spiders away. Just make sure cats or other critters can’t access your yard. Our fence is narrow enough to keep them out (or our puppy will!)

Happy playing! Do your kids love playing in a sandbox? Let me know in the comments below!

    Wow this is a nice setup! Though this is kinda takes a lot of work and our soil outside the house is kinda difficult to dig up. Would probably ask help from others. Thanks for sharing this nice post!

    Another good tip to keep bugs away from the sandbox is to sprinkle cinnamon in the sandbox. Might sound a little crazy but it works
