Har. I guess in a way the horses already have vessel sinks but sadly they are not marble, just plastic:

Thanks for all the feedback and the funnies (LOL! I was so focused on sinks aka basins that I never saw the dbl entendre). I've always wonder about how they stood up to everyday use. Cleaning is a consideration for me - I like a tidy vanity that is easy to keep wiped down so I'm thinking under mount is probably better suited to my taste. I agree they do seem a bit pretentious but at the same time I can see their application when space is a consideration. Also, might be interesting in a main floor guest powder if you had such a home which I don't.
