This kitchen got a head-to-toe makeover in just one weekend. See the rest of the projects. Use a measuring tape, long level, and pencil to mark the location of your shelves. Use a stud finder to locate the studs to ensure the shelves are attached as securely as possible. Editor’s tip: If you plan to have a microwave in your pantry, consider the depth and height of the shelf in the spot you want to place it. Our shelf is 15 inches deep and 12 inches tall and includes a nearby outlet. We recommend hiring an electrician to install a new outlet, if needed. While you’re having the shelves cut to size, make sure to also have the 3/4x1-1/2-inch trim cut to the perimeter of each wall you’re installing shelves. This trim will go under each shelf and serve as a support board. We’ll show you how to install it later on. Once the support boards are installed, attach the shelves. Use the 1-inch screws and drill from the top down through the support boards. Run the H-channel corner shelf brackets in the corner where the two shelves meet. Secure self-adhesive screw hole covers to conceal the screws.
