How To Build A Cabinet For A Wall Oven

Building a cabinet for a wall oven out of stock plywood is an intermediate level project and requires basic tools. The cost of materials, which includes the 30″ x 24″ double wall oven featured, is approximately $150.

Cut the plywood to size.

  • Make sure your circular saw is properly set up and ready to go before you start cutting. Set the depth of cut to 1/8 inch and make sure that the blade is centered on the blade plate.
  • Measure your wall oven and subtract 1/4 inch from its width and length (allowing for a snug fit). This will give you correct measurements for cutting the plywood panels that will form the cabinet’s sides, back, top, bottom, front panel (optional), bottom shelf support board (optional) and lid support board (optional).
  • Place two sheets of plywood together so they’re parallel with each other—and use clamps or tape to secure them—then measure from one end along this first sheet’s edge at 6 inches from where it begins; mark this spot with a pencil line as well as one at every 12 inches toward that end until you reach 15 inches in length; repeat these markings on all 4 sides using both sheets of plywood, then rotate them 90 degrees so their ends are now aligned vertically instead horizontally; measure down 14 inches from each corner between where they meet at their closest point near each end point just marked earlier by measuring across both pieces adequately spaced apart because they’ll be glued together later anyway once assembled into place around whichever item needs protecting inside like cooking utensils stored elsewhere within reachable distance outside their kitchen cabinets’ doors

Cut the pieces for the supports, shelves and face frames.

The next step is to cut the pieces for the supports, shelves and face frames. Make sure that you have your plywood cut to the correct size before proceeding.

Cutting out these pieces will require some simple math. If your wall oven is 30 inches wide by 24 inches deep, then it will take two 15 inch by 24 inch pieces of 3/4 inch plywood for the front and back panels of each side panel. The three remaining sides should be made from two 12 inch by 24 inch pieces of 1/3 inch plywood for each side panel (front edge to back edge). Now that we have an idea about what lengths need to be cut out, we can move on with cutting them out!

Once these pieces are all cut out, it’s time to start assembling our cabinet!

Assemble the cabinet.

Assemble the cabinet. The first step is to assemble the cabinet itself.

Attach it to the wall.

Install the door and drawer fronts.

Step 2: Install a filler strip between the cabinet and built-in refrigerator. You may need to add a filler strip between your wall oven and built-in refrigerator if there isn’t enough space for both appliances side by side. For example, if you’re installing a 30″ wide refrigerator with an 18″ depth, you’ll need at least 4″ of space in front of it for access. This will help prevent heat loss from your refrigerator. If you have trouble finding ceramic tile that matches your cabinets, use rectangular pieces instead of strips so they are more flexible when cutting them down to size. You can also cut pieces from scrap wood or even cardboard if necessary

Attach the cabinet to the wall.

  • Attach the cabinet to the wall. The goal is to make sure that the cabinet is level and properly anchored, so it doesn’t sag in later years. It’s best to attach it using lag bolts (or other large-head screws), which go through the cabinet and into wood studs on the other side of your wall. If you can find these studs, mark their locations with a pencil or chalk before drilling holes for your lag bolts (you’ll be able to see where they emerge when you drill). Use a level as a guide when setting up your drill bit at an angle, so that when you drill down into one of these studs you’re getting it right on target—and not just going straight through into drywall or plaster. Once all four holes are drilled (two per side), place each lag bolt in its corresponding hole and turn until snug but not tight; then use a wrench to tighten everything up until everything feels secure against whatever surface is behind yours: drywall, plasterboard or concrete block masonry depending on where this project takes place.

Install the door and drawer fronts.

When you’re finished attaching the cabinet to the wall and securing it in place, you’re ready to add the door and drawer fronts.

Attach the door and drawer fronts using wood glue. You can also use nails if you want, but they are not necessary.

Install a filler strip between the cabinet and built-in refrigerator.

You’ll need to install a filler strip between the cabinet and built-in refrigerator. Install it at the same height as your cabinets, using 2x4s for its vertical supports and plywood for its horizontal surface. It should be the same width as your cabinet and depth as well. The only difference is that you will want to paint it a different color than the cabinets or just leave it unfinished if they’re already painted.

Install crown molding.

You will need to measure, cut and attach the crown molding. Start by attaching the crown molding to the front of your cabinet. You can use glue or nails to attach it if you like but I recommend screws so that you can easily adjust it if needed later on.

Next, measure and mark where you want your crown molding to start and stop on both sides of the cabinet (you will need two pieces). Cut these pieces off with a miter saw or circular saw so they are even with each other at both ends. Next, take one piece of crown molding outside and place it face down on some sawhorses or something similar (this will protect your work surface from getting scratched up). Then drill pilot holes every 6-9 inches along three sides of this piece including its top edge (you will only have four holes total as one side is not used). Once done measuring make sure all measurements are correct before drilling any holes into them! Finally attach these pieces using screws making sure everything looks level as well as straight when finished

Build it yourself for about $150 in materials

To build this cabinet, you’ll need:

  • A table saw. If you don’t have one, it’s worth buying one if you plan on doing any woodworking. They’re not expensive and they can make your life much easier when cutting plywood or other large sheets of material. You can also rent them at most hardware stores if you are just starting out and aren’t sure whether or not you’ll use it enough to justify the cost.
  • A jig saw. This tool will help make the curved cuts needed on some parts of this project (the supports) as well as cutting out holes for electrical outlets and switches in the face frames later on in this tutorial (see Step 7). It’s also nice because it allows for very fine cuts compared to a circular saw which makes it easy to get into tight spaces like those between shelves or cabinets where there isn’t much room between surfaces that need cut through before making another pass over top once everything has been laid down flat again after removing any dust created by drilling holes into drywall during installation.
  • Router with round-over bits installed so we can smooth out edges where pieces meet up together during assembly later on down line…this helps prevent splinters from forming when touched by bare hands.”


If you’re looking to install a wall oven, you can build a cabinet for it easily. It’s not difficult and it’s less expensive than buying one from the store. With our step-by-step guide and tools, anyone can build their own custom kitchen cabinets.
