Our master bathroom is small and only had one sink. I wanted to have the ability for two people to use the sink at the same time. Our vanity is the right width to add two sinks, but we would have lost the function of the drawers on each side due to the dual plumbing/drains.. This sink was the perfect option for us to adapt the vanity. It has two faucets but one drain and the existing plumbing worked to serve the two faucets.
