An extra-long rectangular wooden sandbox from WITBOSCH offers plenty of play space, unmatched durability, and versatility. Thanks to our unique modular assembly method, you can set up this sandbox quickly and tool-free. Just fill it with play sand and have fun!
When children outgrow the sandbox, it doesn't have to be discarded. The clever modular components can easily be repurposed as a raised bed, planter, flower bed, garden edging system, and more. Our sandboxes are not only an investment in hours of playtime but also in the versatility of your outdoor space.
Finish your wooden sandbox with a black, high-quality sandbox cover of your choice:
Both covers come with mounting plugs, screws, and elastic cord. Prefer another color or mounting method? Opt for a custom-made cover in waterproof tarp or mesh netting.

Our wooden sandboxes use innovative heat-treated wood that significantly improves stability and resistance to insects and rot.
The result? A lifespan of up to 20 years without chemical treatments. Over time, the wood develops a beautiful light-grey patina.
Avoid cheaper chemically treated wooden sandboxes that slowly leach chemicals into the sand. The tool-free design enhances safety by eliminating sharp nails and screws.
*For hard surfaces, ground spikes are replaced by support stakes that match the sandbox’s height. Please indicate this during your order so the correct stakes can be included.
Play sand
A 210 x 107 x 25 cm wooden sandbox requires about 450 liters (675 kg) of play sand. Calculate the needed amount in kg by multiplying the sandbox volume in liters by 1.5. Refer to our sandbox guide for other dimensions.
Stability and reinforcement
For sandboxes taller than 25 cm, the beam connections may slightly bow outward under pressure from the sand. Prevent this by adding aluminum connectors to those connection points on the top layer.
These connectors are included with 37.5 cm high sandboxes. For extra stability on hard surfaces for rectangular sandboxes with a height of 25 cm, we recommend ordering sufficient beam connectors.
