- Reviewed in the United States on August 20, 2025Size: LargeColor: WhiteVerified PurchaseBeautiful sink
- Reviewed in the United States on November 17, 2025Size: LargeColor: WhiteVerified PurchaseJust two or three months and the sink has two chips on the edge. It is frustrating that something that is getting so much wear and tear daily is so poorly made
- Reviewed in the United States on June 24, 2025Size: LargeColor: WhiteVerified PurchaseFirst one came broke and they immediately replaced it. My clients loves their new sink.
- Reviewed in the United States on August 14, 2020This is an amazing sink. Easy to knock out the hole(s) you need for the faucet. It is white though so if you aren't prepared to clean and maintain it regularly, don't get white because it will get stained quickly. Great quality sink!
