Hello shea522,

Thank you for your interest in one of our vanity sets. The bottom of the sink is rounded. Please check the link below. That link redirects you to a listing of the same vanity set, with 2 drawers instead of 2 doors. In picture #4 of that listing you will get a good idea of the shape of the sink.

Let me know if you have any more questions!

Mike
