Kohler K-3820-4 Reviews

Rated 5 out of 5 by from Beautiful Sink but beware Faucet Direct - Excellent products, prices, and service. Sink - Beautiful sink, excellent lines and quality. Bought this sink to replace an existing Kohler cast iron 33x22 sink. Nowhere can you find the cutout dimensions, not even at the Kohler web site. We thought that because it was the same size as the existing sink it would just drop in, Wrong. What should have been a 4 hour project turned in to a 2 day project as I had to cut out 1" more of counter top all the way around (solid surface so not simple). The fastening system is terrible, who ever engineered this should be cleaning toilets. Once installed it is absolutely beautiful. FYI the cutout for drop in self-rimming is 32 1/2 x 21 1/2 and for undercounter install it is 30 1/4 x 16 9/16.

Rated 5 out of 5 by from Beautiful sink I purchased the K3820-4 double SS sink. Despite of a comment I read about the template, mine had a template included. I previously had a Kohler cast iron ceramic sink and it only required a few corner cuts. This sink was deeper than my old 8" depth sink so some plumbing was required. It makes my kitchen look so beautiful. It scratches easily, as does most SS, so I really need a sink basin rack. I give this sink a 5 Star. Also, my first delivery came with a bent corner. FaucetDirect had another sink out to me in less than 1 week. Great service!!!

Rated 5 out of 5 by from Cool looking sink This sink is very stylish for a contemporary kitchen. It is made well and the stainless is strong, if somewhat prone to showing water spots. Cleans up great with a little Barkeep's Friend. We love it!

Rated 5 out of 5 by from Love this sink! We replaced our old composite sink with this double stainless and I'm so glad we did. It's got nice big, deep basins which are great; and the low profile edge is almost as good as having an undermounted sink. I just wish stainless didn't scratch as easily but I don't know how you'd get around that. I was extremely happy with the ordering process, price, and delivery and would definitely use FaucetDirect again!

Rated 5 out of 5 by from Will never shop anywhere else for kitchen Not only was this the best price by far, online customer service was fantastic, and shipping was extremely fast! The Kohler double basin square sink is installed and what a centerpiece to our newly remodeled kitchen! We haven't used the sink yet but the plumbing will be hooked up in a few days. I will return to review then.

Rated 5 out of 5 by from A great transaction I ordered this sink and it was shipped and arrived FAST.However it got a small ding in it during shipping. I had to send it back. Faucet direct were absolutly wonderful in taking my calls and emails with all my questions and returning it with a prepaid label was simple. I was scared at first to make this purchase but now trust and recommend them. I regret not having the time to order a new one as this sink is LARGE, nice and very modern and sleek. Thank you Faucet Direct!
