Love the small, square biscuit color sinks! I bought 3…2 for the guest bathroom and one for one of the separate master sinks. Beautiful!. Keith. Canadian, TX. Sun May 24 2026

[This review was collected as part of a promotion.] The sink is a really nice choice for a 24 inch vanity. I had a beautiful vanity with a custom stone top and this sink is a good depth and allows for about 6 inches of stone to show on all sides. Although it is square, I installed it in a traditional looking vanity in a historic home and it looks right at home here. I think oval sinks are somewhat out of style at the moment so I’m very happy with my choice.. Restorationgal. Fri May 16 2025
