Vessel sinks are very popular! Our Marble Uniques vendor provides us with some great marble bowls as shown in the bottom picture. On our lastest reno project - we used a vessel sink in the main floor half bath. It provides a beautiful natural beauty and calmness to the bathroom.
When considering a vessel sink - it is important to remember to adjust the vanity height to that of a counter top height. A couple benefits - you don't have to bend down to reach the bowl, and the bowl keeps the mess off of the counter!
