Choosing a wall mounted oven is a smart way to maximize kitchen efficiency, enhance design, and create a professional-level cooking experience at home. Whereas traditional ranges use valuable floorspace, a built-in oven frees up space for more flexible layouts while giving your kitchen a sleek, integrated look. But whether you’re building new or upgrading your kitchen, preparation is key to making sure a wall oven not only fits but also works seamlessly with the rest of your kitchen.
This guide on how to install a wall oven will help you understand how cabinetry, layout, hookups, and workflow all play a role in the final result—and how doing it right the first time will help prevent costly mistakes such as picking the wrong size. Learn more from the experts at Albert Lee.

The very first step in preparing for a wall mounted oven installation is ensuring that your cabinetry is ready to house the unit. Aside from assuring it fits, measuring an oven cutout accurately is the #1 way to be sure your setup is working properly and safely.
How to Measure an Oven Cutout
Follow these steps to learn how to measure an oven cutout correctly:
- Measure the Width: Use a tape measure across the front opening of the cutout from left to right.
- Measure the Height: Measure the cutout from the bottom to the top edge of the cabinet opening.
- Measure the Depth: Record the distance from the front of the cabinet to the back wall, making sure to exclude cabinet doors.
- Check the Square: Measure diagonally from corner to corner. If the numbers aren’t the same, your cutout may not be square and might require adjustments.
- Account for Hookups: Consider the location of your electric oven wall outlet or gas oven hookup. Allow extra clearance if your oven requires a recessed box or protruding connections.
Once you have your measurements, you can compare these specs with models by looking up their dimensions in the model guide. The best way to do this is by researching online, where brands provide specific manuals that list the width, height, depth, and clearance all in one place.

How Much Clearance Do You Need for a Wall Oven?
Clearance is an often overlooked part of installing a wall oven. Most models require at least ¼ inch to ½ inch of clearance around the sides and top for airflow. And don’t forget behind the oven for hookups and ventilation. Always check the wall oven installation instructions provided by the manufacturer, since requirements can vary.
What if My Oven Is Too Small for the Kitchen Cutout?
It’s a common misconception that all wall ovens are the same size. In reality, they come in 24-inch, 27-inch, and 30-inch widths. However, special setups, like installing a double wall oven or microwave oven combos often have unique dimensions.
If your oven turns out to be smaller than the cabinet cutout, you have a couple of options.
🔵You can exchange it for the correct size.
🔵Or, in some cases, purchase a trim kit to close the gaps.
While trim kits provide a finished look, they’re best treated as a last resort, since proper wall oven placement and sizing will always deliver the cleanest result.
Why a Kitchen Layout Matters for a Wall Oven Install
Planning doesn’t stop with measurements. Kitchen layout plays a big role in how practical and efficient your oven setup will be.
For example, a galley kitchen with a wall mounted oven installed directly opposite the refrigerator can create a bottleneck every time someone opens a door. Similarly, installing an oven directly across from a cooktop may interrupt the workflow in an otherwise open layout.
When preparing for the installation of kitchen appliances, it’s helpful to think about traffic patterns, ergonomics, and how your family actually uses the space.
Here are some tips for common layouts (CLICK THE ➕TO LEARN MORE).
➕Single Oven Installation
A single oven is the most versatile choice, especially in smaller kitchens. Experts recommend installing a wall oven adjacent to your main cooking station, like a range or cooktop, to streamline meal prep. This setup keeps your cooking workflow efficient and your cabinetry balanced.
➕Double Oven Installation
If you’re installing a double wall oven, keep in mind that these models are tall and can take up considerable cabinet space. It’s important to balance oven placement with surrounding storage so you don’t lose essential cabinetry. With that in mind, be sure to remember door clearance for both the top and bottom compartments. While an oven that sits taller might not have any obstructions, lower oven doors can be an issue if there is a dishwasher, refrigerator, or drawers that open within the clearance zone on the bottom.
➕Side-by-Side Oven Installation
Side-by-side ovens are less common but can provide a unique solution for kitchens with wide layouts. This design keeps ovens at a convenient height and eliminates excessive bending. However, it requires ample cabinet space and thoughtful planning to ensure symmetry and accessibility. Be sure to account for clearance between each unit; in most cases, ovens cannot be installed directly side by side and require a gap of space between each oven. Additionally, be sure there are enough outlets to accommodate both appliances.

Installing a Wall Mount Oven: A Checklist
Even if you’re not handling the installation yourself, it’s useful to understand the process so you can prepare your kitchen properly. Whatever the case, be aware that the average cost to install a wall oven is about $200-$225. It’s worth paying for it to be done right the first time. Either way, the following checklists outline what’s needed for different oven types.
Installing an Electric Wall Mount Oven
✅ Confirm your kitchen has a dedicated electric oven wall outlet (usually 240 volts).
✅Verify outlet placement is within reach of the oven’s power cord but not directly where the oven will sit flush.
✅Review the electric oven installation requirements from the manufacturer before starting.
✅Double-check clearance for wires and ensure the cabinet is properly cut out.
Installing a Gas Wall Mount Oven
✅Make sure you have a proper gas oven hookup installed.
✅Confirm there is also a nearby 120-volt outlet (most gas oven installation setups still require power for ignition and controls).
✅Review your wall oven installation instructions to account for venting and connection clearances.
✅Schedule certified wall oven installers to ensure everything meets local code.
