We NEED this! I especially like that the garbage is not directly under the sink, so that one of us can be at the sink, and the other one doesn't have to say "excuse me" to throw something away (fifty thousand times).
Our kitchen is very roomy, but as far as wanting my trash can out in the open, that is a no-go! So, something like this would be totally ideal. And then it's extra space for something on top, maybe a microwave? :)
