This is a rather Zen style sand pit. Awesome, isn't it? But I guess we will have a much less stylish version for our little one...
I was thinking of getting an IKEA Samla box with lid and maybe a rug for underneath. So the tiles (unfortunately we don't have wood) won't be too hard plus we can collect the sand that will wander out of the box afterwards.
The result will be shown in the next few days!
