Dead fridge, on its back 

Another vote for dead fridge here - but mine is under cover of a canopy - guess it would go quite a few years before it rusted through though?

If you can get a freezer, they are deeper and you just pop the whole bag in, no having to empty bags and spilling stuff. Probably would look tidier than different tubs?
just beware if children about, no doubt they would make good hidey holes :-(
