I know granite countertops need maintenance and wonder how a granite sink would hold up over years of use. We replaced our old sink and tile countertops last year with quartz countertops and a stainless steel sink. I really like a white sink but, as you noted, they do get marked up so stainless steel was a compromise. Quartz looks like granite but that wasn't why I chose it, it's maintenance free and the only cleaner I was told to use was Windex.
