If you are paying someone to install, make sure you open box and check vanity and sink for any damages. The sink came cracked and I had to install it so I can have a vanity/sink in bathroom. I have a special need daughter and need the sink for use. Otherwise, the vanity looks nice. Now I got to see about getting another vanity/sink and try to find someone else to install at a lesser cost.

Broken upon arrival
I opened the top of the box when the vanity arrived and the entire sink top was broken. It wasn't just a little crack, it was a big section of the top that was broken. I contacted Lowe's customer service and they said that I could return it and buy a new one. I asked them for some type of discount, but they said they couldn't provide one. I have now scheduled a pick up for the return of the vanity. If I want another one in a timely manner, I have to go to the store to pick it up. NO COMPEN...

It is so nice to hear from our satisfied customers. Thank you for your review and for shopping at Lowe’s.

Received the item with a cracked sink
I received this item from Lowe's with a cracked sink, I went in to Lowe's on East Broad St in Columbus, OH (store #1211) and they were not willing to work with me to resolve the issue. I would like a replacement of this same vanity with the same price I paid. Now this item is listed as $699 on Lowe's website which is much more then the original price. I would like to be contacted regarding this issue.

Completely scratched and dinged up
The unit was delivered with tons of packaging, so you’d expect it to be in good shape. But the unit was covered in scratches and dings. Now my project is next week, and I’m stuck finding a new vanity. Lowe’s offered a measly 10% off, which wouldn’t even come close to covering the time and money I’d need to repair it. I won’t be wasting my time or money with Lowe’s anymore. Don’t waste your money on this vanity.
