Granite countertops are being used more frequently in kitchen designs than ever before. A floating granite countertop can be a nice addition to kitchens already utilising the stone, as this can produce a seating area within the room. Granite counters can extend as much as 14 inches past the cabinetry on their own, provided they are the correct thickness of 1 1/4 inches and have been properly attached to the cabinets. If you wish to have a countertop extend much farther than this you will need to secure the counter from below with a piece of sheet metal to buttress the integrity of the stone.

Place the steel plate on top of the cabinets where you wish the counter to be secured. The plate should extend from the edge of the back of the cabinets, past the front of the cabinets so that it forms a ledge on top of which the floating granite countertop will be placed. The granite will further extend outward by 4 to 6 inches.
The steel plate should also be 8 -12-inches smaller than the granite in width, so position it in the centre of the cabinets evenly. There will be a space on either side where the granite will sit directly on the cabinets.
Drill holes into the stainless steel plate where you will bolt it to the cabinet below. Check the position of the plate, and drill the holes either directly into the cabinet's sides, or stiles, or into the plywood support, which is supplied to support a granite counter. Make sure the bolts are placed evenly to support the plate at one end, while the plate supports the granite at the other. Use a variable speed drill and mark the place to be drilled with masking tape to keep the drill from slipping off the metal when you begin. A 1/8-inch steel plate is thin enough to drill through with a standard drill bit on one pass.
Bolt the stainless steel plate to the cabinets by tightening down the bolts through the holes you've drilled with a wrench.
Apply a bead of epoxy around the edge of the steel plate and across its centre in the form of an X. Lift the granite counter onto the steel plate, centre it and lower it into place. The epoxy will hold the plate to the granite and will be hard enough to hold the granite fast within ten minutes. The granite can now extend as a floating countertop as far out as you desire.
Tips and warnings
- If this counter will not have any cabinet beneath it at all, purchase a steel plate that is 1/4 inch thick and that is bent in an "L" shape. Bolt the short end of the L directly to the studs in the wall that the counter will be coming off of and attach the counter to the steel in the method described above. The thicker plate will lend the additional support that the cabinet would give.
