Sand pits - how should they be covered?

[Toptack]

We're thinking of putting a sand pit in the garden for the DCs, but I'm worried that the sand will end up wet and manky very quickly. Should it have a water tight lid (eg tarp) or a slatted wooden affair that will let water in, but will also allow air to circulate?

Won't you wait until spring, before such a venture, as too wet and cold now, surely?

If it is to have raised sides, I would think an all-over marine ply, or rigid plastic, cover, with sides to fit over the sand pit box - like a giant shoe box with a lid might do it.

Watching with interest - I have a leaky ill-fitting tarp which doesn't work at all.

A decade ago I had a pair of big blue rigid plastic boats from John Lewis. One for sand and one for a lid.

The lid doubled as a water course or paddling pool.

You bought them as separates but you just bought two boats- they weren't different.

Be prepared for sand being trailed through the kitchen.......

Thanks for replies. It's a ridiculous time to do it, I know, but it's for DS1's birthday. He actually really wants one of those mini ride-on excavator things, so box has to be big enough and low enough to accommodate one of those. I was thinking about a wooden one because they blend in with the garden a bit more, but maybe plastic with lid is the way to go...

I would just be prepared to buy a lot of new sand. I have yet to find a truly watertight cover and the and goes mouldy quickly.

I have a wooden one. It didn't come with a lid so DH built one (also from wood). It's not watertight but it does stop the cat from using it as a litter tray. We just replace the sand every spring. It does get a bit of mud in it from the rain but it's still a lot cleaner than playing at the beach. It only needs a few bags so maybe £10-15 to replace each year.
