Unddermount Dobuble Bowl Sink

If I only knew!!!

 from California– Verified Buyer

If I knew the maintenance required for a stainless steel sink I never would've have purchased one. This sink is impossible to keep shiny and clean. And after just a couple weeks it already has a few rust spots. Calling Kraus to see what they suggest. I really wish I would have gone cast iron, but it's too late now.

good quality kitchen sink

 from Los Angeles, CA– Verified Buyer

The double bowl works well for us. The smaller one is surprisingly usable for stacking dishes waiting to be washedrinsed. The two grids that came with the sink are excellent at preventing wear and tear to the sink.

Great deal for outstanding quality

 from Rutherfordton, NC– Verified Buyer

The sink itself is wonderful. I love the size of the two bowls. The larger one is big enough for my largest bowls and pans, and the smaller one is great for prep work. The bonus is the inserts. They make all the difference. They help keep the sink clean, and make it so you can set glasses or other items in the sink and they sit upright and don't fall over. I never would have guessed how much I would love them. The sink came very well packed in a nice soft bag (wrapped in styrofoam, etc), and arrived quickly. The only problem - they accidently sent me two! Customer service had the second one picked up the day after I called.

Was this helpful? Yes / No

Top quality.

 from Quebec, Canada

Perfect quality, everything is protected inside the box with foam (around and inside the sink), also the sink is in a cloth pouch for more protection and the box is very thick almost like wood.
Come with 2 grid and stainers...I will recomend to all.
