Kohler k-3821-4 Reviews

Rated 5 out of 5 by from Great buy-Easy installation-Quality I am a 74 year old widow woman. I removed the old sink and installed this new one, all by myself. It is even better than I expected. It was easy to install and deep and high quality construction with plenty of sturdy places to pull it down into place and be nice and straight on the counter. It is advertised as kind of a modern in design but goes well with my antiques and sort of ties everything together. The square design is very roomy and the solid brass basket strainer and soap dispenser are perfect. All Kohler brand. Delivery was fast and as offered on the sight.

Rated 4 out of 5 by from best purchase I absolutely LOVE this sink! Pros: sleek contempary design, awesome self-rimming edge, size of sink basin, ease of cleaning. Cons: the width between the pre-drilled holes. With the 4 hole sink, I was unable to put my faucet in the middle hole because there was not enough room for the soap dispenser on the right side of the faucet. I ended up putting 2 soap dispensers on the left side, with the faucet off set to the right. I still LOVE the sink, but wish more options were available for drilling the holes.

Rated 5 out of 5 by from Great Kitchen Sink My wife loves this sink. We bought it to replace a double basin sink that she was very unhappy with. All of her largest skillets and pans fit flat to be soaked. Oven racks were easy to work with also. Our high rise faucet and the depth of the sink work well with canning and boiling pots. The single drain, located further back, affords much more room in the sink cabinet. The technical specs state that the basin rack is not included so we ordered one with the sink. When it arrived, we found that our sink did indeed have a basin rack included. When I asked to return the extra rack, FaucetDirect made it a painless effort. They promptly sent a prepaid return label and my account was credited within just a few days. : ) The install was pretty straight forward. I would suggest the use of a tape measure to layout the countertop cut. This sink has a large basin that needs to be placed correctly. Front to back, I only had 1/4" to play with. That measurement took into consideration the rear lip of the sink to the back countertop roll and the front sink mounting rail to the inside cabinet front. My front and back cut had to be within 1/8" to center up. That's tight! Side to side was no problem but, I would still recomend the use of a tape measure over the supplied template. I'm very happy with FaucetDirect. Their shipping was fast and their customer service is great. They had no problem with a price plus match when I found a lower price on the sink. When I needed to return the extra basin rack, they made it happen. Thanks FaucetDirect.

Rated 5 out of 5 by from Love my sink!!!! My husband always thought I was kidding when I kept asking for a new sink for christmas and my birthdays for the last 10 years. Well, this year he finally got me the sink I had been waiting for. I love this sink. It's large and deep. I can put my biggest dirty roasting pan in it to soak and you can't even see it unless you're standing over it. It is very modern in design and I love how flush it is with the counter. My husband and 16 year old daughter installed it along with a new touch faucet in about 3 hours including the tear out of the existing sink. Installation was fairly easy although my daughters small hands came in handy for attaching the front retention clips. I also received the sink rack and love that product as well. We ordered the sink on Tuesday and received it on Thursday. Great job Faucet Direct!

Rated 5 out of 5 by from Kohler single basin sink This is a beautifully, simple single basin sink. I love how flat it sets on top of the counter edge.

Rated 5 out of 5 by from So happy with this sink! We had this sink installed just over a month ago as part of our kitchen renovations and are so pleased we did. The size is great for every day use and even better for those days when there are lots of large pans and roasters to soak. This sink is easy to clean and the included rack is a bonus. We are finding it a beautiful addition to our new kitchen and have received plenty of compliments!

Rated 4 out of 5 by from Best Sink Ever Love, Love this sink even more than the granite counter tops I installed with the sink!! Extra deep, very clean lines, and flat rim. Although description says Top-Mount/Under-Mount 2 contractors that I spoke with would not install it as a an undermount as Kohler made the lip very narrow and very difficult to do as under mount. We did the top mount over the granite and I think it sill looks great since the lip rim is very flat and flushed against the granite.
