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.

We love this undermount sink. The color compliments the countertop so nicely and the quality is exactly what we expected

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.
