I've been meaning to do this for quite some time now. I have a bunch if pallet slats I got off CL to build our fence. I use them for little projects like Mini-WSM tables. I had a 18"x18" concrete paver that I used for the top. Going to be painted blue to match the deck. The top is at 16", which puts the top of the lid at 42". This is a perfect height for me.
