I have a large vanity in our home , 4 bedrooms and the main bath has one sink that needs updating. When I was raising 3 daughters in this home I wished I had a two sink vanity in the main bath. Now that I'm able and thinking of future selling value, what are the draw back of these sinks? I put in a white one piece sink in his down stairs bath..mistake..all the dust from his electric shaver is forever a concern.
