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!

AMAZING SINK :)

I LOVE MY SINK. I LOVE THE DEPTH AND WIDTH OF IT. IT'S PERFECT AND WHEN I GOT IT AND IT HAD THE METAL RACKS IN IT, I THOUGHT I WOULDN'T USE IT, BUT I LOVE THEM.! YOU CAN SIT HOT STUFF IN THERE. IT ALSO LETS THINGS DRIP OFF EXCESS WATER! THE SINK IS GOOD QUALITY. I COULDN'T BE MORE PLEASED!!! I chose the 60/40 and I really do like that because the 40 is big enough for most cleaning and then the other sink is drip dry because of the rack :). I would definitely recommend this to anybody who's looking for a new sink.
