Hello, this vanity is sold as a set and vanity alone is not available. There are two cut outs in the back almost center. One measures 10 1/2"x15 3/4" the other is 19 1/2"x15 3/4". The lead time for processing order is about 48 hrs and 7-10 business days shipping to 10026.

Thank you. And the bottom drawer is NOT full length to allow for plumbing, correct? How much width behind the bottom drawer is available for plumbing?

Sorry, which cut-out is which of the previous post - top vs. bottom? And is the first number the width or the depth?

All four drawers are full function..the cut outs are 10 1/2" wide and 19 1/2" wide. The 10 1/2" would be on the right side if looking at the front of vanity. The cut outs end just above the bottom drawers. Hope this helps.
