    Will it void the warranty to somehow remove the clips and simply use caulk?

    Thank you for contacting Karran. Clips are not necessary for installation if clear silicone is used to mount the sink. If you need further information, please contact customer service at 866-452-7726.

                Great product but issues with clamps and instructions
                So far really like the sink. It’s very sturdy and should hopefully last a long time. The instructions were very basic and lacking detail. I could not get the under side clamps to work at all to clampdown the sink. They have screws but don’t actually clamp down and no real instructions for them. After an hour of trying to get them to work I saw that many others have had issues with them and Karran has acknowledged the problem but hasn’t done anything to fix it yet. I’m hoping that the weight of the sink and the silicone will hold the sink in place but big design flaw in my opinion. If clamps had worked properly and instructions had been more clear I’d probably give it 5 stars

                Beautiful sink
                Gorgeous sink! Easy to install. Pre-drilled holes made adding faucet and soap dispenser easy. Very deep basin, perfect for large pots. Also, purchased the stainless rack for inside to hopefully keep it's condition "new" for a long time to come.

                Beautiful big sink!
                Absolutely love how big and open the sink is! So easy to wash dishes and big pans. I don’t know if it’s possible, but I’m afraid it will stain, so I make sure I clean/dry the sink every time I’m done washing dirty dishes.

                Looks good
                I had one of the mounting tabs break off and it is hard to drill out the holes for the faucet without a special saw

                Beautiful Sink!
                I love this sink! It's beautiful and the water beads off when wet. It looks gorgeous in my kitchen.

                A Beautiful Addition to our Kitchen
                We love our Karran quartz kitchen sink. The Bisque color blends perfectly with our granite countertop which contains similar hues. The 30" x 22" drop-in sink is very well made, fits perfectly and was easy for our plumber to install.

                This is a veery nice sink
                I replaced an old cast iron porcelain sink with this single bowl sink. I did remove the clips on the underside of the sink. They didn’t work for my application. The sink fit perfectly in the countertop opening. A bead of silicone and waiting 24 hours secured the sink to the countertop. I did need two more holes. It was nice having holes pre drilled from the bottom side. A 1 1/4” diamond drill completed the holes easily by drilling from the underside. I wasn’t sure about the instructions for completing the holes. They said to hit the center of the red dots located on top of the sink with a ball peen hammer. I tried that but was afraid I would break the sink if I used more force. Overall a very nice sink. I would recommend it.
