    5.0 out of 5 stars Quality - glad we bought it.

    D.1. · April 12, 2025

    Looks nice, cleans up easy, doesn't chip, has a deep drain screener to catch debris, if you have hard water like we do, the spots easily come off easy with a spray calcium-lime remover. Quality item - glad we bought.

    5.0 out of 5 stars Looks great.

    Was wary of a black sink, but it looks great and cleans easy. It does scratch though, so get a guard for the bottom.

    5.0 out of 5 stars Good quality sink

    A.C. · January 20, 2025

    I’m really happy with this sink- it has a matte/ low luster finish that I feel will hold up better to my cast iron pans and heavy pots over stainless steel options- it looks nice and has plenty of room for my large pots and pans. I purchased this product as "Used like new".

    5.0 out of 5 stars I LOVE this sink

    L.H. · December 25, 2019

    I fell in love with this sink as soon as I found it on Bolo. Read the reviews and felt confident that this was a great product with a perfect price point. Was on alert for cracks when delivered, but we lucked out-- arrived in perfect condition.It is gorgeous in person. So roomy. And it has a little sparkle in the right light, which I also love.The only flaw we could find was the mounting equipment. This is a heavy sink, and the brackets were not up to the job. Ended up bracing it from underneath with boards.

    4.0 out of 5 stars I would say I am happy with the quality and the appearance

    D.G. · February 22, 2015

    We recently remodeled our kitchen with Bianco Antico granite which is a lighter colored stone with patches of dark grey/brown. We originally had a white enameled cast iron sink (with the old counter tops) and we wanted something really sharp and modern looking. Given a choice, I probably would have preferred a single large sink, but the wife overruled me and insisted on a 50/50 sink with two equal sized bowls.After shopping around a LOT, we finally settled on this unit. Overall, I would say I am happy with the quality and the appearance, but I think we could have done a little better. For one thing, the bottom of the bowls seems slightly small/narrow. I really wanted a nice, large sink that could easily accommodate large pots/pans for soaking, but this just doesn't quite cut it. Yes, I was aware of the dimensions before ordering, and on paper this sink seemed to be the right size, but installed it just feels a little smaller than I would have preferred.That really isn't a negative comment about the sink. I am sure it's exactly the size we ordered. I just wish that the actual dimensions were a little larger....and for what it's worth, I don't think many sinks would fit that criteria -- pretty much everything I looked at in the big box stores and online was a similar size....and most were actually smaller than this. So maybe I need to adjust my own expectations?Final thing -- this is my first "granite composite" sink. I like the concept, but I dunno -- it looks nice, but my guess is that 99% of people who look at the sink would guess that it's just solid plastic.....because that's how it looks. It does have a very thick, solid feel to it, but it still ends up looking a little like plastic.If I sound unhappy with the sink, I'm really not. Would I order another one? Probably -- unless I could find something that was clearly way better.

    5.0 out of 5 stars Visually Stunning with the Quality to Match

    S. · August 13, 2019

    This sink is absolutely stunning in our new kitchen! We took a gamble as it seemed 50% of the reviews mentioned cracks upon receiving, so we were hesitant, but ours arrived unscathed! No cracks! And it seems like it will be very durable and scratch resistant, which is important to us as we only use cast iron to cook. We’re about a week in from install and have used it almost every night to wash heavy cast pans & a large griddle, with no issue! It should be of note that when our stone guy came to measure for our counters he mentioned, unprovoked, this brand was of the higher quality sinks he’s seen/installed. (Purchased the InSinkerator flange separate from Bolo) Will update if any issues arise

    5.0 out of 5 stars Lovely sink that functions well for a family home

    J.K. · November 9, 2014

    I adore my sink.The Kraus single basin is huge and perfect for washing big dishes and pans. It stays pretty clean, but I always make sure to wipe down the sink after doing dishes. Since it's black, it dries a little different than how it looks when wet, but I love it.I haven't scrubbed it with any type of cleaner except a sponge and soap. I'm not sure if there are certain things you shouldn't use. When reading the instructions for a Blanco sink (which was our first consideration) I read that you weren't supposed to use abrasive cleaners.Installation was fairly easy. We did it our selves using a combination of the clips provided and a Hercules sink setter since our counter didn't have enough space for the clips in the front.We've had our sink for 4 months now.

    5.0 out of 5 stars Very good quality

    Looks great, nice built in filter basket

    E. · December 16, 2023

    The only down side is typical for all under mounting units in that is very deep in the cabinet, leaves short space under or beside the drains for water distribution valves, led drivers, storage items and waste bins. I got it All in but it took careful space planning and sequencing of installations to get it all to fit in a 36” wide cabinet.

    Woooow la verdad es que la estética de la tarja es increíble, resalta en la cubierta. yo la instale sobre la cubierta para que contrastara el color negro con mi cubierta gris. Es de muy buena calidad y los accesorios como la contracanasta estan geniales.lo único que noté después usarla es que se mancha con las gotas de agua, por lo que debes pasar un trapo para que no queden esas gotas por lo que le pongo un 96 % de calificación.
