Rectangular wooden sandbox

The extra-long wooden sandbox. Extra durable. Extra beautiful.

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.

Advantages of our wooden sandboxes

• Quick and tool-free assembly
  Assembly without tools, thanks to handy ground spikes* that connect the modular wooden beams.
• Modular and customizable
  Design a sandbox that perfectly meets your needs: opt for extra large, extra tall, or unique shapes like U-, L-, or plus-shapes. Increase the height from 25 cm to 37.5 cm for additional play depth. Add corner seats for extra comfort. Extensions, widening, or height adjustments are possible later.
• Durable, natural wood
  Made from 4 cm thick thermally treated spruce (Thermowood), free from chemicals and with a lifespan of up to 20 years.
• Optimal rainwater drainage
  The included non-woven geotextile base ensures smooth drainage and prevents the washing away of play sand.

Quality sandbox covers

Finish your wooden sandbox with a black, high-quality sandbox cover of your choice:

• Mesh netting: keeps out animals and debris while allowing rainwater to clean the sand naturally. Ideal for spring and summer.
• Waterproof tarp: protects against animals, debris, and harsh weather. Perfect for autumn and winter.

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.

Thermowood: durable, natural, and safe

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.

Tips

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.
