I would like some advice with my kitchen island. It's ~72" x 42" granite countertop (i believe 2cm)
My contractor says that it'll be fine to have an 18" overhang but what i'm reading from various sites is 10"-12" overhang max. So now i'm worried.
I have a drawer, sink, and dishwasher cabinet on this island. That leaves 18 inches overhang. I was worried about it so I purchased 3 corbels ~ 4.5" d x 9" height x 5.5" wide. This will still give me ~13" unsupported overhang. I dont want to worry about it falling over or cracking if someone by chance jumps on it to sit or something.
Cabinets is made of maple and the rest is made of plywood.
plywood (as an underlayment?) will be placed under the granite that will span the majority of it. I'm not sure if the 42" includes the 2" overhang on the cabinet side or not. It's a pre-fab 42"
Is their enough support for my overhang?
On an off note, how do I install an undermount sink if there is plywood under the granite?
