Love this sink!

We chose this Karran white quartz sink for a complete kitchen renovation! It is lovely to look at and is very efficient in design. The double bowl allows for flexibility in use and the low divider makes it easy to transfer dishes, pots and pans between sinks. I have found it easy to keep clean!

Best sink ever!

By far the best sink we have ever had. It is deep enough to actually hold and wash dishes. I can set them up to dry right on the other side. Perfect for our family. The sink is beautiful. I haven't noticed any dried water or soap spots. I love that the racks in the bottom of the sink help protect it but can also allow water to be drained underneath. The drain cups/stoppers are so fancy. The additions are nice too! I definitely recommend this product.

Best sink ever!

Who knew I could ever get so excited about a sink! The drain plug is amazing. It has a flip cap that allows food scraps to go in but keeps a lid on so it leaves the sink cleaner. The plug easily pushes down when you need it to hold water the lower center wall allows you to work without getting all wet and the cutting board, colander, and dryer rack are super useful and stable. The white matte sink responds quickly to bar keepers for a clean finish. I am a total fan!
