Questions & Answers

What is the reach from the faucet installation hole to the sink drain hole? That is, if I want the stream of water to flow directly down the middle of the drain hole, how far is that from the faucet?
ByJun 14, 2025
1 Answer | 
Answer This Question

This particular measurement would be approximately 7 1/2” needed for the faucet to be directly over the drain hole. If you need further assistance, please contact Karran customer service at 866–452–7726 or via email at info@karran.com. Thank you.

    My husband poured paint remover in the sink - now it has white spots! Is there something to recoat it with to cover them up??
    ByApr 22, 2025
    1 Answer | 
    Answer This Question

    Thank you for contacting Karran. The paint remover has eaten away at the finish, causing the white spots. Unfortunately, there is nothing that can be used to bring the finish back. If you need further assistance, please contact Karran customer service at 866–452–7726 or via email at info@Karran.com.

            Is the concrete a grey or a brown base? hard to tell from the pix. Want to install with an acacia countertop and sage cabinets. Dont want it grey, and tan looks too light and the brown is too dark.
            ByMay 19, 2024
            1 Answer | 
            Answer This Question

            We consider the concrete color to have more of a taupe look. For a complementary color chip, please contact customer service at 866-452-7726 or via email at info@Karran.com. Thank you.

                  Beautiful sink!
                  This sink is beautiful! The 32" open bowl is great for washing large items and the rack in the bottom is sturdy and a heavy gauge protecting the bottom of the sink. The color is perfect!

                  One Big Bowl - quartz
                  I love my new sink. The one large bowl makes it so easy to wash refrigerator shelves and large items. The gray color is perfect for my new countertops. I also am loving having the under mount as well, just brush those counter crumbs right into the sink.

                  I replaced my cheap stainless steel sink that easily scratched with this black quartz sink that is both stylish and function. My old sink had poor drainage. This one drains great. I love all of the accessories that come with it. Buy it.

                  Awesome upgrade!
                  Very nice sink! Upgraded from a stainless steel sink and I’m very pleased. Fluids move towards the drain with rounded corners so no food sticks. Straightforward installation. A great custom look!

                  Great sink
                  I bought this sink primarily because it helped solve a design issue with my kitchen remodel - wanting to shift the sink to the right to center under a window. The offset design allowed that to happen with no in-wall plumbing changes. On top of that, I like its large size and it worked great with my quartz countertops. My only caution is not to let food scraps sit overnight as it can stain but cleans up easily with regular soap.

                  Simple yet elegant sink
                  Nice deep bowl with drain in back makes for a wonderful working sink. The gently curved back is a sophisticated touch and adds a bit of elegance to your kitchen. Nice gray flecked interior goes well with my white quartz countertops and brushed stainless hardware.
