SANDigz sandbox plans are modular – so you can build a sandbox that’s just right for your family, your budget and your backyard. Just want a sandbox? We have plans for that. But, since this sandbox design is customizable you can also add the water station, sandbox cover, shade and mist system or toy box at any point in time. These do it yourself sandbox plans are carefully designed to help you install the perfect sandbox. If you are visiting to find The Sahara Sandbox, please visit the about me page.
