Build an Outdoor Granite Countertop in 4 Steps Build an Outdoor Granite Countertop in 4 Steps

Today's outdoor kitchens are rivaling their indoor counterparts for sophistication, including such upgrades as a granite countertop. If you are planning to use granite on an outdoor countertop, you will find the following 4 construction steps useful.

 Here are the materials and tools you’ll need:

  • Power Drill
  • 1 1/2-inch flathead wood screws
  • 2x4s
  • 3/8-inch Plywood
  • Rotary saw
  • Adhesive such as Gorilla Glue
  • Granite Counter Slab  

Step 1: Choosing Your Countertop Size

Determining the size of your countertop before you begin construction is important for three reasons: 1) it will tell you the size of wood pieces you’ll need, 2) it will tell you what size granite slab you’ll need to order from your supplier, and 3) you’ll want to build the top of your counter at a height from the floor that will be most convenient for the person who will be preparing the food.

Step 2: Choosing Your Countertop Location

In considering location, you’ll more than likely want your counter near your outdoor stove or grill where you’ll be doing your cooking, because it will be on this counter that you’ll be preparing your food. Another important consideration in choosing location is related to socializing with guests you’ll be sharing your meal with. You’ll most likely want to talk with your guests as you are preparing your food, so you’ll want to built your counter near the socializing area.

Step 3: Building Your Counter Framework

If your plans include adding cabinet storage space below or above the counter, you will need to include a framework to include these cabinets. You might even want to build a small wall behind your counter and cabinets. These are all considerations you’ll need to take into account when you build your framework. (Directions supplied here do not include those for adding cabinets or a wall.)

You’ll also need to take into account the weight of the granite countertop your framework will be supporting. You can determine the approximate weight of the granite slab with the help of your granite supplier. The counter stand, the supporting structure of your counter, will need to be strong enough to hold the weight of the granite slab you’ll be using, and will therefore need to be constructed of 2-inch wood, either 2x4 or 2x6.

Step 4: Adding Your Counter Base and Granite Slab

When your framework is constructed, cut a piece of plywood to fit the top of the framework, then attach the plywood base to the framework, using wood screws. Apply adhesive to your plywood base and lay your granite slab on the plywood, taking care that the edges of the slab are all even before the adhesive sets up.

After cleaning the surface of your granite countertop you’ll be ready to impress your dinner guests with your new countertop and the first gourmet meal you will have prepared on it.
