Plywood Under Granite Outdoor Kitchen Countertop

QUESTION:

Can you put plywood under granite counter top for an outdoor kitchen?

ANSWER

Yes you can, but there isn't necessarily a need to so long as the outdoor kitchen cabinets effectively support the granite countertop.

Now, if you are installing granite tile, then yes you will need a surface to lay the tiles on.

If you do use plywood, use marine grade and cover with a waterproof membrane to keep water/moisture away from the plywood otherwise it will rot and warp in time.

Not as big an issue with a granite slab, but with a granite tile outdoor kitchen countertop water is more likely to find it's way to the plywood, so the membrane is important.

Good Luck,
