What Is a Microwave Cabinet and Why Build One?
A microwave cabinet is a purpose-built enclosure designed to hold a microwave oven at a convenient height. It can be open-faced, with shelves that leave the appliance visible, or fully enclosed with doors that hide the microwave when it is not in use. Some versions include drawers or side cabinets for storing cookbooks, baking sheets, or small kitchen appliances.
The main reason to build one instead of buying a ready-made unit is fit. Mass-produced microwave carts and cabinets come in standard widths and depths that may leave awkward gaps or block nearby outlets. When you learn how to make a microwave cabinet yourself, you can build it to the exact width of your microwave plus a few inches of clearance on each side. You can also match the wood species, stain, or paint color to your existing kitchen cabinets for a seamless look.
Benefits of a Custom Microwave Cabinet
A custom build frees up counter space for food preparation, which is especially helpful in small kitchens. It also protects the microwave from dust and grease when the doors are closed, potentially extending the life of the appliance. Proper ventilation space built into the design helps prevent overheating, and a dedicated shelf keeps the microwave at ergonomic height so you do not have to bend or stretch to use it.
From a resale perspective, built-in style storage appeals to home buyers. A well-made microwave cabinet looks intentional rather than like an afterthought, and it can increase the perceived value of your kitchen without a full remodel.
Common Placement Options
You can install a microwave cabinet under the counter next to your oven, which keeps the appliance at a comfortable working height. Wall-mounted versions save floor space and work well in galley kitchens. Corner units make use of otherwise wasted space, while freestanding cabinets offer flexibility if you rent or plan to move in the future. The placement you choose will influence the cabinet’s depth, height, and mounting method.
Planning Your Microwave Cabinet Project
Good planning prevents costly mistakes during construction. Before you cut any wood, gather the actual microwave you intend to store, or at least its exact manufacturer specifications. Sketch a simple design with measurements, and decide whether the cabinet will be open or closed, wall-mounted or floor-standing.
Measuring Your Microwave
Measure the width, depth, and height of the microwave with the door closed, then measure again with the door open at a 90-degree angle. The open-door measurement matters if you plan to place the cabinet against a wall or next to another cabinet, because the door swing needs clearance. Add at least two inches to the width and depth for airflow and easy insertion, and add one to two inches to the height if you want space above the unit.
Write down the numbers and label them clearly. It is easy to confuse width and depth when you are standing in the lumber aisle, so keep your notes with you when you buy materials.
Choosing the Right Location
Pick a location near a grounded electrical outlet. Microwaves draw significant power, so avoid using extension cords if possible. Make sure the spot does not block a primary walkway or interfere with the refrigerator door, dishwasher, or oven door. If you are mounting the cabinet under a counter, verify that there is enough toe-kick clearance and that the microwave will sit at a height comfortable for the primary user.
Determining Cabinet Dimensions
A typical countertop microwave is about 20 to 24 inches wide, 14 to 18 inches deep, and 12 to 14 inches tall. Your cabinet should be roughly two inches wider and two inches deeper than the microwave, with an interior height at least one inch taller than the appliance. If you plan to store a cookbook or baking tray on a shelf below, add another 12 to 15 inches to the overall height.
Sketch the cabinet as a simple box with a top, bottom, two sides, and a back panel. If you are adding doors, plan for a face frame or direct-mount hinges. If you are building an open shelf, you can skip the doors and focus on a clean front edge.
Selecting Materials and Hardware
Hardwood plywood, such as birch or maple, is a strong choice for the cabinet box because it resists warping and accepts paint or stain well. Pine is more affordable but softer, so it may dent more easily over time. For the shelf that holds the microwave, use three-quarter-inch material to prevent sagging under the weight of the appliance.
You will also need wood glue, screws, sandpaper, and a finish such as polyurethane, paint, or stain. If you are adding doors, purchase concealed hinges, knobs or pulls, and magnetic catches to keep the doors shut.
Tools and Materials You Will Need
You do not need a professional workshop to build a microwave cabinet, but having the right tools makes the job safer and more accurate. Most of these tools are common in home toolkits or available for rent at hardware stores.

- Stud finder
- Level
- Safety glasses and hearing protection
Recommended Materials
- Three-quarter-inch hardwood plywood for the box and shelves
- One-by-two or one-by-three lumber for face frames or cleats
- Wood glue
- One-and-one-quarter-inch wood screws
- Finishing nails or brad nails
- Sandpaper in 120 and 220 grit
- Paint, stain, or polyurethane finish
- Hinges, knobs, and magnetic catches if adding doors
Step-by-Step Guide: How to Make a Microwave Cabinet
This step-by-step guide walks through the core construction process. Adjust the dimensions to match your microwave and the available space in your kitchen.
-
Cut the cabinet box parts. Using your measurements, cut the top, bottom, back, and two side panels from three-quarter-inch plywood. Cut the shelf that will hold the microwave to the same width and depth as the interior of the box. Label each piece so you know where it goes during assembly.
-
Assemble the frame. Apply wood glue to the edges of the side panels where they meet the top and bottom. Attach the sides to the top and bottom using one-and-one-quarter-inch screws, driving them through the outside of the top and bottom into the edge of the sides. Use clamps to hold the pieces square while the glue dries. Check for square by measuring diagonally from corner to corner; both diagonal measurements should be equal.
-
Install the back panel. Cut a thin back panel from quarter-inch plywood or hardboard. Nail or screw it to the back edges of the box. The back panel adds rigidity and prevents the cabinet from racking or wobbling.
-
Build the microwave shelf. Position the shelf inside the box at the height that leaves enough clearance above the microwave. Support it with cleats—small strips of wood screwed to the inside sides—or with adjustable shelf pins if you want flexibility. Make sure the shelf is level before fastening it permanently.
-
Add ventilation space. Microwaves generate heat, so do not build a tight box with no airflow. Leave at least two inches of space on the sides and back, and at least one inch above the unit. If you are adding doors, consider drilling a row of small holes in the back panel or leaving a gap at the top rear for heat to escape.
-
Add doors or leave open. For a closed cabinet, attach hinges to the door panels and mount them to the face frame or directly to the cabinet sides. Install knobs or pulls and a magnetic catch to keep the doors closed. For an open design, sand the front edges smooth and apply edge banding or a thin strip of hardwood to hide the plywood layers.
-
Sand, finish, and mount. Sand all surfaces starting with 120-grit sandpaper and finishing with 220-grit. Wipe away dust with a tack cloth. Apply paint, stain, or polyurethane according to the product instructions. Once the finish is dry, move the cabinet into position. Use a stud finder to locate wall studs, and secure the cabinet through the back panel or top rail into the studs with screws. Check that it is level before loading the microwave.
Design Ideas and Customization Options
A microwave cabinet does not have to be a plain box. With a few design choices, you can make it a functional part of your kitchen rather than just a place to store an appliance.
Open Shelving vs. Closed Cabinet
Open shelving keeps the microwave visible and easy to access, and it costs less because you do not need doors or hardware. It works well in modern kitchens where appliances are part of the decor. A closed cabinet hides the microwave and protects it from splatters, but it requires hinges, handles, and more precise construction so the doors align correctly.
Adding Drawers and Storage
You can add a drawer beneath the microwave shelf for storing microwave-safe covers, utensils, or small appliances. A narrow pull-out shelf on one side can hold baking sheets or cutting boards. If you have space above the microwave, a small cabinet can store cookbooks or decorative items. Keep in mind that every added feature increases the weight of the unit, so reinforce the mounting hardware accordingly.
Matching Existing Kitchen Cabinetry
To make a custom microwave cabinet look built-in, use the same wood species and finish as your upper or lower cabinets. If your kitchen has painted white cabinets, paint the microwave cabinet white and use the same style of knob or pull. Adding a face frame that matches your cabinet doors creates a cohesive appearance even if the box itself is made from plywood.
Pre-Made vs. Custom Microwave Cabinets
Many homeowners wonder whether to buy a ready-made microwave cart or build a custom cabinet. The table below compares the two approaches across several practical factors.
| Feature | Pre-Made Microwave Cart | Custom Built Microwave Cabinet |
|---|---|---|
| Fit to space | Standard sizes only | Exact dimensions for your kitchen |
| Style matching | Limited finishes | Matches existing cabinetry |
| Ventilation control | Fixed design | Custom airflow gaps |
| Storage options | Usually open shelves | Drawers, doors, or open shelves |
| Cost | Often lower upfront | Material cost plus your time |
| Installation | Usually freestanding | Can be wall-mounted or built-in |
A pre-made cart makes sense if you need a quick solution and rent your home. A custom cabinet is worth the effort if you own the space, want a permanent fixture, or need an exact fit around outlets and other appliances.
Tips and Best Practices for a Sturdy Build
Measure twice and cut once. This old carpentry rule still applies, especially when you are working with expensive plywood. Cut all your pieces before you begin assembly so you can lay everything out and confirm the fit.
- Use clamps during assembly to keep joints tight while the glue sets.
- Pre-drill screw holes near the edges of plywood to prevent splitting.
- Check for level at every major stage, not just at the end.
- Use a stud finder and screw into wall studs when mounting the cabinet.
- Leave a small gap between the back of the cabinet and the wall for cord access and airflow.
- Apply finish to all sides of the wood, including the back and bottom, to help prevent moisture absorption.
Common Mistakes to Avoid
One of the most frequent errors is building the cabinet too tight around the microwave. Without enough clearance, the appliance can overheat, and you may struggle to slide it in and out. Always add at least two inches to the width and depth of the microwave when planning the interior.
Another mistake is ignoring the door swing. If you place the cabinet next to a wall, the microwave door may not open fully. Check the open-door measurement before you finalize the location.
Some DIYers mount the cabinet only with drywall anchors, which cannot support the weight of a microwave over time. Always anchor into wall studs or use a cleat system that distributes the load across multiple studs.
Finally, do not skip the finish on hidden surfaces. Unfinished plywood edges can absorb kitchen humidity and swell, causing the cabinet to warp or delaminate over time.
Frequently Asked Questions
Do I need advanced woodworking skills to make a microwave cabinet?
No. A basic microwave cabinet is essentially a box with a shelf, which makes it a good beginner project. If you can measure, cut straight lines, drive screws, and sand wood, you can complete this build. The step-by-step instructions in this guide cover each part of the process in detail.
How much space should I leave around the microwave for ventilation?
Aim for at least two inches of clearance on the sides and back, and about one inch above the unit. If you are enclosing the microwave behind doors, leave a gap at the top rear or add small ventilation holes in the back panel so heat can escape.
Can I mount a microwave cabinet on the wall?
Yes, but you must secure it directly to wall studs using screws or a French cleat system. A microwave can weigh 30 to 50 pounds or more, so drywall anchors alone are not safe. Check that the cabinet is level before loading it, and avoid placing heavy items above it.
What type of wood is best for a microwave cabinet?
Three-quarter-inch hardwood plywood such as birch or maple is a strong, stable choice for the cabinet box. Pine is less expensive but softer and more prone to dents. For the shelf that holds the microwave, use thick material to prevent sagging under the appliance’s weight.
How do I hide the power cord in a microwave cabinet?
Drill a hole in the back panel near the bottom corner, or cut a notch in the back panel where the cord can pass through. Position the cabinet close enough to an outlet so the cord reaches without strain. Never pinch the cord between the microwave and the cabinet wall.
Is it cheaper to build or buy a microwave cabinet?
Building usually costs more in time but less in premium features, because you choose the materials and skip retail markup. A basic pre-made cart may be cheaper upfront, but a custom cabinet offers a better fit, longer life, and a look that matches your kitchen. If you already own basic tools, the material cost for a DIY cabinet is often modest.
