I am planning a kitchen remodel and I have been looking into hanging some kind of stone-ish shelves on one wall. Surprisingly, I'm having a hard time finding much information on the feasibility of this idea. I know that these shelves will be very heavy, but I wonder if it is possible to anchor them to studs through the drywall, or if I will need to do something more difficult to ensure that the shelves are stable. Does anyone have any experience with this?
Anchoring them to studs is just fine, your main problem is going to be getting brackets that will support that amount of weight. The amount of weight each bracket will support will be printed on the package. I would consult your granite or stone supplier for weights of their products.
You MUST make sure that you're anchored into studs, though, and preferably with three inch wood screws that are NOT drywall screws.
