Installing a granite countertop for a bar
I want to put a granite countertop on a bar - what kind of supports are needed? The countertop will be sitting on top of a wall - on one side there will be kitchen cabinets, but about 6 inches lower than the bar height (normal cabinet height) - the other side will be available for seating with bar stools. I'm concerned how much of an overhang is needed for the seating, what kind of support is needed on the seating side, and how much of an overhang is reasonable on the cabinet side (to make the countertop a suitable depth). And what needs to be done to the wall to support all this?
Thanks
