8'x6' 3cm ganite w/ 15" unsupported ovehang?
We are designing our kitchen island. The cabinetry is roughly 7'6" x 4'6". We are specing a 3cm granite counter - one slab.
The question is the overhang on one of the long sides is going to be a cabinet height bar front with four stools. Thus, one of the 7'6" sides will have a 15" overhang.
Again, the stone will be about 7'8" x 5'9", which includes a 1" overhang on three sides and a 15" overhang on one of the long sides.
We are getting conflicting recommendations regarding whether or not this 15" overhang needs to be supported.
Installer #1 - it needs legs
Installer #2 - it needs corbels or hidden L brackets
Installer #3 - it needs bars imbedded into channels cut into the bottom
Installer #4 - it normally would need support, but because the % of overhang is only about 17%, support is unnecessary
I do not want any visible support. Legs are absolutely out. I would prefer to avoid corbels because they do not fit our "look" and will be a knee-knocker. I would consider L brackets. imbedded bars sound like they remove as much strength as they add. Can I get away with no support at all?
