HI - not sure if this is the right place to ask this - but here goes. I have a vessel sink that is 16.5 inches in diameter : would a vanity with depth of 18 inches and a vanity top that has a depth of 19 inches be big enough for this sink ? Or should I go with a bigger vanity and top ? I can put the faucet off-set : maybe at about 10 or 2 o'clock. Thanks - - BILL
