Help finding a small sink

Maybe think outside the box a bit. If you cannot find a sink that meets your needs, can you find some waterproof container that you can put a hole in the bottom of? I'd think, for example, a stainless steel mixing bowl would work nicely as a hand sink, and could pretty easily be mounted in a little countertop with some adhesive caulking or whatever. Adding an overflow drain near the top on one side would probably be a good idea so it won't overflow onto the floor of the RV.
