Rated 5.0 out of 5.0 by FARMHOUSE LOVE We love our new sink. It's huge! Single bowl is the only way to go. We get compliments all the time from friends and family. It's beautiful, unique and perfect. So happy with this purchase. We got the faucet from Home Depot as well and love it too. February 20, 2015
Rated 5.0 out of 5.0 by All Around Awesome Appliance! This kitchen sink is, in my opinion, the best one around. Before, we were using a double sink with the divider in the middle. This was an honest-to-goodness headache for my wife and I! We had virtually no room to work in the sink together, much less by ourselves. The kitchen sink was simply a storage place for our dirty dishes. Those days are so gone now thanks to this farm style sink. My wife and I can finally do dishes together and blaze through cleaning time, in no time! And with a kitchen faucet with a sprayer head, it allows my wife and I to take turns using that to spray the dishes down. And we have created a system for where the dirty dishes go in the sink for when we are ready to get going. We are just amazed by how much of a difference changing the sink has made. And the front curtain really stands out and really blends with our stainless steel appliances. There is a crease in the corners to the center, so not to worry about standing water too much! Installation was very straight forward; if you watch the install video on this page, you will get a better understanding of what to do. Depending on whether you are doing a new install or a retrofit install, the instructions clarify what you need to do in each situation. In our case, it was retro fit. There are some included templates to assist you with where to jigsaw, and a cardboard template that helps you figure out if the curtain will work with the cabinet. Our biggest problem was when placing the sink into the open space. All of the steps we followed were properly executed, however, the previous sink was installed a bit further back than it was supposed to be. This resulted in a tiny open space behind the new sink. We are probably going to have to update the countertops at some point, and we have a dry cloth behind the sink to cover this open line of space and catch any flying water from slipping into this space along with silicone to fill in that gap as we really don't have many other options right now. Everything we did was correct, but the previous installer of the sink did their part incorrectly. Besides this, we are not disappointed with the sink at all. Everything else fit properly and tightening the clips underneath was quite easy. Piping was a different story. I took about 3 or 4 trips getting different PVC fittings from HD. As always, the associates there were extremely helpful. Going from a two drain hole sink to a one drain hole sink changed things up a bit! But we were able to get it, eventually. Also the sink does not include a drain, so definitely look into getting one of those, along with plumbers putty. And now for the final segment ... stress testing. So, of course, Thanksgiving Day was a great time to use our sink! It was also a good time for visitors and friends to put some scratches on our sink, yes, the sink we just installed 24 hours prior! It was about five smaller scratches. And really this is the only downfall to any stainless steel appliance or sink; they are prone to scratches. And after a year, you really just don't think about it too much because the scratches will be all over the sink and start to blend in. Just the way it is! But functionally, I really enjoy being able to clean all of my dishes with class, and more space! And the next time I move, I guarantee I will buy one of these sinks again, and make sure the previous sink was cut out and installed correctly! December 14, 2014
Rated 5.0 out of 5.0 by Gorgeous sink My wife loved this sink so much she let me cut the quartz countertop to get it installed (we had a shallow 33" sink). This sink is huge and very sturdy. It easily holds your largest pots and pans for soaking - I had some deja vu about working the wash sink at my fast food job 15 years ago. It even quieted our garbage disposal. Beautiful and well-built - highly recommended December 10, 2014
Rated 5.0 out of 5.0 by HUGE but AWESOME Sink This sink is HUGE. We had a two bowl sink prior to this one. We were hesitant to covert to a single bowl, but are very glad we did. I highly recommend a quality faucet to use with this sink. The size of the sink looks a lot larger than our previous one, but really isn't that much larger when you look at the measurements, but this one LOOKS a lot larger than what we had in there before. We also are ordering a rack that goes in the bottom of the sink to help protect it from becoming dented and scratched by Pots and Pans. We are a LITTLE concerned about water spots and how CLEAN the sink will look, but hope that the rack at the bottom will help conceal any waterspouts. Instillation wasn't HARD, but does take some planning. My only true concern was once I cut my countertops there was NO going back. Watching the instillation videos (available online by Kohler) reading the instructions (more than once) and using the templets that come with the sink will make the process MUCH easier. I am pretty skilled with pretty much anything home improvement related, but I did find using the resources MUCH more helpful than normal. Be concise and precise with your planning, cutting and instillation; because any errors will result in LESS than desirable results. This is NOT your typical/simple sink install or replacement.

Rated 4.0 out of 5.0 by The farm with a twist We've wanted to get a farm style sink for some time, but to be honest didn't consider stainless steel until we saw this model. It looks great and matches the rest of our SS appliances. The large single basin is fantastic. (can't stress this enough) I love that I can toss large pots and pans completely in the sink with no problem at all. Sheet pans? Easy. Need to soak the lasagna dishes? Piece of cake. Installation was fairly straightforward and it took me about half the day to wrap it up. I found it really useful to watch the step-by-step video Kohler has on-line. I used a combination of a jig saw and an oscillating tool for the cuts and thought that worked really well. I admit It's a little weird to cut into your perfectly good countertops, but the included guide keeps you honest. I would highly recommend getting a faucet with a sprayer hose. The basin is so big it's really useful to rinse out the entire sink. Two things to note: If you live in a place with hard water like I do be prepared to wipe down plenty of surface area that will inevitably have hard water spots. (i know, it's stainless) Also, you're going to need two pieces of wood to mount to the inside of of your cabinet. Instructions say they must be 1/2" or thinner. 1/4" really seems ideal, but who has that laying around? I ended up buying two 24"x2"x1/4 pieces of oak "hobby board" and that worked great.

Rated 5.0 out of 5.0 by Farmhouse Love We love our new sink. It's beautiful. My husband was initially concerned that it would look too industrial, but not at all, he loves it. It's huge and that's a plus. Part of our remodel project. Lots and lots of compliments from everyone who sees it. Would not go back to a double bowl. February 12, 2015
Rated 5.0 out of 5.0 by Easy and Simple Kitchen Upgrade! This sink is just what we were looking for. This sink replaced a double drop-in sink. The single bowl gives us flexibility to do more in the kitchen. Large and deep, the sink sits almost flesh with the counter top, the size was perfect for us. Although there is some countertop that is needed to be removed, it was easily done with the templates provided. Whole process can be done in a few hours or less. We now have gained some space under the sink due only needing plumbing for one drain. Having a double sink prior, one side had a garbage disposal. This was easily changed out to the new single drain sink without any problems. The multiple holes allow for our purified water tap and dish soap dispenser to fit right in. The stainless is sturdy and modern. The apron front is great for those messy times, easy to clean and covers the getting the cabinets dirty. November 9, 2014
Rated 4.0 out of 5.0 by Looks great Purchased this as a remodel job, instructions were great and videos were great, no problem with the install what so ever. I even got lucky and the previous plumbing lined up!! The only suggestion I have is use a couple of spring clamps to hold the front of the template in place while you trace it. Make sure your counter tops are even. If not shim as needed. The slightest tilt in any direction will cause water to pool in one corner or the other in the sink. Lastly, I wish they would have finished the sink to a bit smoother finish, looks rough compared to the stainless appliances. big sink, wife loves it. great modern look July 12, 2014
