What Customers Are Saying
The vanity top offers a modern, sleek design that can help update a bathroom, but many customers reported quality issues like scratches, chips, cracks, and uneven surfaces. The sink basin was also criticized as being too shallow. Compatibility with matching backsplash and side splash pieces was another significant concern, as these had to be purchased separately and were often unavailable. Overall, the vanity top may be a decent budget option, but customers should carefully inspect the product and be prepared to address potential quality and compatibility problems.

Counter tops are nice but very unhappy because I ordered them online and had them shipped and they both came damaged

Requires a 3 hole faucet.

Edging on all sides
I ordered a diffenent sink and the front was just a slope. This sink has about a 4inch flat ledge in the front which is what I loved about it. I only gave it 4 stars because it is not a very deep sink but I am still very happy with the purchased.

Delivery driver dropped off (1) obviously damaged product. See delivery pictures. Other item was ok. Please take responsibility for broken product and don't leave it up to the client to have to sort out and return.
