How To Build A Cabinet Box

When it comes to building cabinets, one of the most important steps is building the cabinet box. The box is the foundation of the cabinet, and it needs to be strong and sturdy to support the weight of the doors and drawers. In this article, we will go over the steps for how to build a cabinet box.

Materials Needed

Before we get started, let’s go over the materials you will need to build a cabinet box. You will need:

  • Plywood
  • Table saw or circular saw
  • Drill and screws
  • Wood glue
  • Clamps
  • Measuring tape

Step 1: Measure and Cut the Plywood

The first step in building a cabinet box is to measure and cut the plywood. You will need to measure the height, width, and depth of the cabinet box. Once you have your measurements, use a table saw or circular saw to cut the plywood into the appropriate sizes.

Step 2: Assemble the Box

Once you have your pieces cut, it’s time to assemble the box. Apply wood glue to the edges of the plywood and use clamps to hold the pieces together while the glue dries. Once the glue is dry, use screws to secure the pieces together.

Step 3: Add Shelves

If you want to add shelves to your cabinet box, now is the time to do it. Measure and cut the plywood for the shelves and attach them with screws.

Step 4: Add Backing

To make the cabinet box even sturdier, you can add backing to it. Measure and cut a piece of plywood to fit the back of the cabinet box and attach it with screws.

Step 5: Sand and Finish

Once the cabinet box is assembled, sand it down to remove any rough edges. You can then finish it with paint, stain, or varnish to match the rest of your cabinets.


What type of plywood should I use?

When building a cabinet box, it’s important to use a high-quality plywood that is strong and durable. Look for plywood that is at least 3/4 inch thick and has a smooth, consistent surface.

Do I need to use wood glue?

While it’s not necessary to use wood glue, it does help to make the cabinet box stronger and sturdier. If you opt not to use wood glue, make sure to use plenty of screws to secure the pieces together.

How many shelves should I add?

The number of shelves you add will depend on the size of your cabinet box and what you plan to store in it. Generally, two or three shelves are sufficient for most cabinets.


Building a cabinet box is an important step in building cabinets. By following these steps and using high-quality materials, you can ensure that your cabinet box is strong and sturdy enough to support the weight of the doors and drawers. With a little bit of patience and attention to detail, you can build a cabinet box that will last for years to come.
