Flat kitchen sinks work mostly because the facuet in kitchens usually swivel, so that you can move the flow of water to flush things out of the corners. In my own apartment I have a directional, tilting head [1] attachment. It lets you point the water stream anywhere within the sink, and it has a secondary mode that turns the stream into a wider shower-style spray. I have a flat sink in my bathroom. It's slighty sloped, but that doesn't help much against gunk collecting in the corners; it's awful precisely because the faucet doesn't swivel, and the faucet is one of those low, short bathroom types, so adding that same attachment would not help much.
