What Customers Are Saying

Customers overwhelmingly praise the sink's stunning black finish that elevates kitchen aesthetics, particularly with white granite or quartz countertops. Reviewers highlight exceptional durability, resistance to scratches and stains, and effortless maintenance requiring only routine cleaning. The spacious single-bowl design accommodates large cookware and features a deep well ideal for soaking. Many appreciate the softer material protecting dishes and the optional matching accessories that enhance functionality. A few note minor concerns like depth preference or water usage, but these rare drawbacks do not diminish the overwhelmingly positive reception.

Karran sink

Finally got it installed and it seems to be a very good quality sink. Loving it.

Rich looking solid sink

Would Recommend

Really big sink easy to install no waterspots and looks more elegant than Stainless Steel. Only knock is there is no option for Kholer disposal with mathing the color. o I had to use the original Stainless steel. Would have been nice to have a matching one but still love the sink.

Karran black sink

Would Recommend

We finally had the sink installed in our kitchen renovation. I think the sink looks beautiful and have gotten many compliments. Somehow, it already has a small divot/chip in it which is disappointing. I've always had the bottom grate in so don't really know how that happened.
