What is part # for disposal compatibility?
Asked by Egood0227 September 18, 20201
AnswerEgood0227, my name is Jessica with Kohler Customer Service. I am happy to assist with your inquiry. If you will be using an existing disposal with K-5871-5UA3-0, you could use K-11352 disposal flange with stopper in place of a Duostrainer. Thank you for choosing Kohler.

Are the sides of sink straight (as in sides of farmhouse sink) ?

AnswersHi, this is Laura with Kohler Co. I am happy to assist you with your question. The sides of the sink are not exactly vertically plumb but are slightly wider at the top.

Sink installation
[This review was collected as part of a promotion.] Gorgeous sink! This sink has amazing depth and scale to enhance any cooks kitchen. We just remodeled out 100 year old kitchen and maintained the vintage look and feel of our Tudor home - this sink paired with soapstone counters looks and works incredibly. I cannot say enough great things about it!

I spent a lot of time deciding on a sink for my kitchen remodel. I even went to Kohler to see all their sink designs (as no store in my area has the Riverby in stock). The Riverby line has a number of variations (size/depth). I love the look, and the quality is amazing. It comes with some accessories that are useful, but personally, I would have preferred the wooden cutting board (available separately) instead of the plastic colander/board that is included.

I absolutely love this sink! We had it installed in June 2019- it's beautiful and spacious. It has more than enough room to wash a large cast iron pot easily in the basin. The additional accessories included with the purchase of the sink are really nice; especially the stainless steel grate which seems indispensable as it protects the sink from accidental scratches and dings. It is a sink that is definitely worth buying!

I've only had my sink a few days but so far I LOVE it. It looks great and is nice and big. I also love the added accessories (I did purchase the bottom drain grate separately). I went back and forth between a two and one basin sink and I think I will be really happy that I went with one large basin. So far it has worked well to wash some big pans without that never would have fit into my double basin sink.

Love it
Beautiful sink! This was the spark for a kitchen update and we based our counter tops around it, we liked it so much. Goodness this thing is heavy though. (I mean I guess thats good) At first I had some doubts about the mounting brackets but they've held just fine with a full tub of water, or dishes. So far so good on the durability aspect too, with pots and silverware a-plenty no issues to speak of. We're actually thinking about a second one for the laundry area if that's any indication of a product endorsement.

A Beautiful and Durable Sink!
[This review was collected as part of a promotion.] I've had this sink installed now for almost 2 years and it still looks just as beautiful as when we first put it in. The Kohler Cast Iron cleaner is great for cleaning the scuffs from pots and pans. I HIGHLY recommend a Kohler cast iron sink over any other product!
