buy a $17 willow kitchen bin with the flap top lid. it allows air flow, is square so fits into smaller places better and holds about 15 nappies.

I also have mine high like Kim....up on the bench in the landry
I bought one of these two weeks ago, and it rocks! No smelling and easier than the bucket with lid hald ajar, just have to get DH to put them in there now instead fo leaving them on the bench in the laundry
