Hello there! Thank you for taking interest in out Gela collection vanity.

The vanity is manufactured in one piece, so the sink, countertop, and vanity base are already pre-assembled for you. The only thing you will need to do is to connect your plumbing system to the sink and faucets (faucets not included). You will also need to mount the backsplash onto the wall.

Hope this information is useful to you!
