After much deliberation and internet searching we decided to try and make one instead of buying one. We seem to have accumulated excessive amounts of scrap wood so decided to try and make one instead, saving cash and clearing our garage in the process.
Hubby cut four lengths of wood with a jigsaw to made the edges of the sandpit before nailing them together with a nailer. The nailer ensured the corners were strong and helped make the frame tough and solid. If your franme doesn't turn out to be too solid you can always reinforce corners with a small chock of wood on the inner corners. 
One the sides were joined together he nailed on the bottom panel. A lot of wooden sandpits nowadays don't come with a bottom, you're expected to use a waterproof sheet underneath the sand and I'm not really a fan of this style and much prefer a solid box so the sand stays in one place. The panel we used was left over from the outdoor chalkboard we made, this is the size we worked round. Rather than cute the main flat board, we found it easier to cut the frame pieces to match it.
I painted the edge with English Primrose Valspar exterior paint. I used about half a tester pot on two coats of the sandpit. The tester pots only cost £2.38 from B&Q and a little goes a long way. Valspar is my new favorite paint. The colours are fab and you can paint anything.
I left the sandpit to completely dry overnight and then stocked up on play sand. It took 3 bags of sand which cost £2.99 each. The worst part was lifting them in and out of the car, I now have muscles like Popeye!
As you can see, the sand didn't stay in the sand pit for long, so technical the little man has a 'sand area' rather than sand pit.
I can't believe how quick and easy the sandpit was to make. It's the perfect use for old wood and a tiny drop of paint.Our next task is to create a lid to protect the sand from the weather.
What you will need
4 pieces of reasonably deep wood cut to size to create the frame (prepped for outdoor use)
a base piece of wood
some bright coloured outdoor paint
lots of sand!
