I am considering updating my masterbath w/ cult marble tub, tub surround and dbl sink vanity. A couple places offered integrated rectangular vanity sinks, which caught my eye, just b/c they were different and more masculine looking. Unfortunately, the mfr that gave me the best deal on all the other components does not offer rectangular sinks. They claim the molds cost $700 and they think rectangular sinks are "dated."

Also, should the vanity be the same type materials and color as the tub/surround, although the bathroom is small, there is a door separation the tub & vanity?
