We just remodled our bathroom, and a few weeks after installing our new vanity and countertop, the sink fell out of the marble counter. The store where we bought it is standing behind us, and the company that manufactured the unit is co-operating very well too. That being said, the unit could not be repaired in our home, so today, they replaced it with a quartz countertop and sink. We were told that it is an upgrade, and perhaps it is. I don't know. I do know that I like the idea of having a maintenance free counter top. But this is the first time I've considered quartz. They didn't want us to be with out a counter and sink, so they installed the closest colour counter they had in stock, with the understanding that if we don't like it they will fix up the old marble counter and reinstall it. The new counter seems to match the cabinet better than the old, and it looks ok. It just isn't marble, and I'm not sure if we should ask for the old counter back. Would you prefer quartz to marble?
