These cabinets were custom built for the project. If you're able to work with a local craftsman they can add the details that will help define your style and look. If you are trying to order 'stock' items you can work with the person that is going to install the piece and they might have some 'go to' lines for you to look at for the project.
If you do not want to make a custom vanity than this one by Empire is pretty similar (you can purchase it with different countertop options)- http://www.qualitybath.com/product~ID~4189.htm .
