    • Love it!

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.

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.

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!

I bought this sink to go in my kitchen remodel. My granite extralarge slab was over $3k including the fabrication of it. The sink style was cut into my slab. I've had this new kitchen for 2 months and the sink stains horribly. I can't put any type of sauce, dirty water or anything of color in the sink. There is a brownish tint around the drain where the slan is due to stuff just staining on it's way down the drain. Also cleaning any pans causes black scuff marks that are also impossible to remove. This is THE WORST sink and the customer service is ZERO, ZILCH, NADA! They sell you junk and then let you deal with it. I never write reviews, but this is to upsetting due to my all in costs to let this slide. Do not buy this sink from this company or other companies selling the exact same thing. I know because i bought the Molesen one too and they are exactly the same! Please go a different direction, otherwise if you do any cooking you will be so so sorry. ... show more
