Nice size and shape, great price. Returning because the quartz composite looks very cheap and plastic like to me. Almost like one of those temporary sinks you would put in a laundry room.

This Karan Undermount Quartz sink is gorgeous! It goes perfectly with my Quartz countertops as well. It’s easy to clean, very large, and quite a statement in the kitchen! I love it!

This sink gets marked up SO easy!!! It sucks and I definitely DO NOT recommend! If it gets a pan scraper across the sink, it gets a mark. You honestly have to scrub it very hard with.a Mr. Clean to get the marks off. The longer we have the sink, The header it is to remove the marks. A friend tried to warn me of the material but I read her the "Scratch proof" part of the description. I am so annoyed I didn't listed to her. I am now looking for a fireclay sink that is drop in since I can't install another undercount easily. Watch out, this sink is NO GOOD!!

Bought two of these in brown. One for the kitchen and one for the bar. Did away with my double sink and I love them. 5 star!
