What Customers Are Saying

Customers overwhelmingly praise the vanity for its elegant design, rich walnut finish, and solid construction with soft-close mechanisms that operate smoothly and quietly. The marble countertop delivers a high-end appearance, and generous storage transforms bathrooms effectively. Most reviewers highlight excellent value and describe themselves as very satisfied. A few report sink durability concerns or faucet compatibility issues requiring upgrades, but these drawbacks are far outweighed by positive feedback, with most customers stating they would purchase again.

Nice but cheap

It comes mostly assembled and looks quite nice. One of my handles snapped off in less than a month of use however. They are really thin, and Lowes doesn't have replacement parts in store or online. I feel like this shouldn't happen on a one thousand dollar item.

Absolutely LOVE this vanity!

Would Recommend

Bought this vanity kit to replace the outdated one in our new 1960's home and the install and finished product couldn't have been easier to install. LOVE that the top and backsplash piece are included. Great quality for a great price. Would definitely purchase again. Having the extra tip out "drawer" at the top is a perfect spot for toothbrushes!

Disappointing Quality

Would Not Recommend

The vanity itself is gorgeous, but the countertop quality is truly disappointing. Within the first week of installation, I noticed etching and water spots forming. I don’t have hard water, so I’m at a loss as to how this is happening on a countertop that’s supposedly already sealed. I’m honestly surprised Lowe’s would put their name on something of this quality. To make matters worse, they don’t sell replacement parts, so this is what I’m stuck with in my newly remodeled bathroom
