    • Love it!
Color: White Size: 15" X 17"
We purchased this sink for our island and it's perfect! It's also easy to clean. It looks nice with our white granite countertops. It's the perfect size for an island.

Color: Black Size: 16" X 18"
The beautiful sink. When I put the cooking utensils in it, it leaves scratches. But I will immediately wipe off these scratches with soap and water, so so far these scratches have disappeared.

    • Don’t buy this sink.
Color: White Size: 31" X 18"
I loved this when we first put it in but a week later, it already has a stain that won’t come out even with the pink stuff. I clean it multiple times a day but DH poured out leftover coffee an didn’t rinse, and now theres a brownish stain. It’s like the material is porous which is ridiculous in a sink. Don’t buy this. It’s junk. Regrets, I have them. ... show more

This is a beautiful sink! Looks great in our remodel. No stains yet but if I do find any I always keep Barkeeper's Friend handy. This is a great sink. Very pleased so far!
