Question: Is this a seamless sink, i.e. no welding? Why are there crease lines leading to the drain? I don't see crease lines on other comparable sinks.
Document: I was concerned about this before it was installed, but have been pleasantly surprised.3. Scratch resistant, not scratch proof. Definitely use the bottom grate.4. Does not completely drain without using the sprayer to get all areas - not a big deal, but does not 100% self drain through the lines at the base.Overall, I'm happy with the sink. Everyone that has seen it LOVES it.Update after using the sink a year and a half:A.
I never thought a kitchen sink could be worthy of an adjective like &#34;beautiful,&#34; but this one is. Clean lines, easy to clean, drains well, manages noise well. I love washing dishes in this sink! (...also bought a Delta Touch2O -Trinsic - faucet, which helps). Also super easy install (added disposal instead of using included drain).
The inside corners of the sink aren't as smooth as I would like. Other showroom sinks I've seen have been smoother, like Kohler ones, but those are easily twice the price and don't come with the drain parts or grates. The grate, while useful to keep you from scratching the sink bottom, would probably be more useful if it only covered half the sink or if it came in two halves.
The other issue was the fact that it is SO big that its hard to drain. In smaller sinks everything goes right to the disposal without worry. With this sink you do need to get an extending, hose faucet because you will have to spray to get everything down the drain. It's not a big deal, but if you are lazy, your sink will get dirty quick!Regardless, its a great sink for the price. Our kitchen looks beautiful and I'm so glad I went with a big sink!
This sink is absolutely beautiful and it's shipped in a bag within the box and when you first open it up and see it freaking glistening it makes your heart smile. The quality of the sink is great, everything looks great. It comes with a nice grate to protect it from getting scratched by pots. MY ONLY GRIPE is how it drains water. The angle of grooves to the drain isn't steep enough.
Reviewed several brands of sinks. For this price you will not find a 16 gauge, 10" deep stainless steel sink. Big box stores......BOOORING! This thing arrives and you think it's a bathtub. Opened it up and  lugged it out of the well packed box. Cha-Ching! Offset drain allows for more under cabinet storage. Combine all this with free 2 day shipping and no sales tax. Unbeatable.UPDATE!
I can never go back to a double bowl. And the Kraus made my kitchen remodel amazing beautiful I wish I can upload pics for everyone to see with this review.
I remodeled my kitchen and purchased this under mount kitchen for the large island in the middle. I went with Kraus assuming that it is a good brand and this will translate into good quality. The sink developed stains at the base within few weeks of its use. This is supposed to be STAINLESS and I was shocked to see those stains. Since the sink has been under mounted, there is nothing that I can do at this stage expect never to buy Kraus products again
Ours is installed undermount - the lip is sandwiched between the granite countertop and the plywood (which you can't see, but is used to support the granite).
Purchased this more than a year ago for a kitchen rennovation. Sink is extremely high quality - no complaints. I get lots of compliments on its style and size - glad we didn't skimp on this purchase. You use sinks multiple times a day - this is an area worth investing in.
Answer: yes
