Kohler K-2356-4 Reviews

Rated 5 out of 5 by from Great buy Beautiful overmount sinks for a great price!! Arrived in 2 days is perfect shape. We ordered 2 for a new bathroom and they look fantastic. FYI, the drain is located in the middle of the sink so the distance between the faucet and drain is farther than normal. As such you will need to find a longer pivot rod to be able to use the drain plug (most of the standard faucets you buy have a shorter, standard pivot rod).

Rated 5 out of 5 by from Great looking sink!!! :) Sometimes it's tough making a purchase on line when you can't exactly see the product right in front of you. Especially something like a sink!! I didn't see anything I liked in the usual stores like Home Depot or Lowes that was at a reasonable price, so I found this sink from this website. The sink is perfect! Looks great, functions great, great price too for the item! Very pleased with this purchase, and would surely use this company again in the future for any needs I may have. Thanks FaucetDirect! :)

Rated 5 out of 5 by from nice appearance and fit I needed a sink that would fit the opening of a bathroom counter top in an apt building buildt in the 1960's. The counter top was still in great shape and we did not want to replace it. (None of the local hardware stores had any that fit in stock.) I found this one on line and have been very happy with the style and fit. I have purchased 3 of them so far. All installations have gone fine except on 1 sink. One of the sinks was not level on the bottom. I had to gently scrape some ceramic upraised area off of the bottom; probably left from the molding process. I hope to purchase 1-2 more in the future. They really look nice! I think the price is reasonable and the shipping is well done! Thank you. Bob

Rated 5 out of 5 by from Only Sink That Fit My Grandma needed a new sink and of course wanted me her Grandson to do it for her. I didn't want to go through the hastle of replacing the entire vanity top so I looked around for a drop in sink that would fit the hole opening of her current vanity top which is over sixty yrs old. Luckily I found this one and it not only looks great, but did fit the countertop hole. The price is pretty good as well. The only problem I've noticed is due to the position of the drain I needed to add an extension to both the drain pvc tubing and the pop up drain ball rod as well. I'm ordering a second one right now for her other bathroom. So to recap great sink, great price, and most importantly it fits. Thanks TC

Rated 4 out of 5 by from Looks great This is a great looking sink. There were good comments from previous reviewers. The drain is further from the faucet assembly, so that may be a factor in your installation. This sink has a great amount of workspace, ie the bowl is very large. Make sure you measure your existing bowl area to ensure you will be happy. This was actually slightly smaller than my original, but still plenty of room. There were other sinks like this style that were going to be way too small, so make sure you look at the bowl sizes when shopping around.

  • Does this come with the drain assembly?

    A. This item is the sink only and does not include the drain assembly.
