I’ve never done a waterfall island before and need help. This is the island my clients want. It appears to be manufactured stone. What kind of stone is typically used in these and how much does it cost? Also, I like the thickness of this. Our normal countertop guys only do 2”, this looks like 4”. Is it one thick piece or hollow? I’m close to Houston, so if anyone knows somewhere in Houston that does this, please let me know.
