15. Over-the-range vs built-in microwave: our pick

An over-the-range microwave combines a microwave and a range hood above the cooktop. A built-in microwave fits into a cabinet or wall opening and usually needs a separate hood to vent the range.

The choice turns on what you want to keep above the cooktop and how much install work you're ready for. An over-the-range unit fills that space and vents it, while a built-in clears the space and leaves the venting to another part of the kitchen.

Over-the-range vs built-in microwave at a glance

An over-the-range microwave mounts above the cooktop, sits on the wall or cabinet and vents the range through a built-in fan. It's a common choice because it does two jobs in one box.

A built-in microwave goes into a cabinet opening, a tall cabinet bay or a wall oven stack. It frees the space above the cooktop, but it needs a separate range hood if you want the cooktop vented.

What an over-the-range microwave does for the kitchen

An over-the-range unit saves counter space by moving the microwave off the counter. It also gives the cooktop a fan, so you don't need a separate hood above the range.

The trade-off is height and reach. A tall unit above a cooktop can feel crowded, and the controls sit above the burners, so you reach over the heat to use them.

The over-the-range microwave dimensions guide helps you check the height before you order.

What a built-in microwave does for the kitchen

A built-in microwave sits in a cabinet or a wall opening at a height you choose. That can put the controls at a comfortable level and keep the cooktop area clear.

Most built-in microwaves don't include a fan, so the cooktop still needs a hood. The hood can be a wall range hood, a ceiling hood or a downdraft unit, depending on the kitchen.

A built-in makes the most sense when the venting plan is already settled.

Space above the cooktop

An over-the-range unit fills the space above the range, which can be a plus or a minus. Some cooks like a clear wall above the range, while others value the storage a cabinet gives.

A built-in leaves that wall open. If you want the space above the cooktop for a hood, a shelf or a clean wall, the built-in is the better fit.

Venting the cooktop

An over-the-range microwave vents the cooktop through its own fan, using a duct to the outside or a recirculating filter. The fan sits above the burners, which is where smoke and steam rise.

A built-in needs a hood to do the same job. The hood's fan, duct and install are part of the plan, so compare the whole setup, not only the microwave.

The venting options guide explains the two main setups.

Install work and the cabinet

An over-the-range install mounts to the wall and cabinet above the range and ties into the vent path. It's a single job, but it still needs a licensed electrician for the outlet and a qualified installer for the mount.

A built-in needs a cabinet cutout that matches the unit, an outlet in the right place, and often a trim kit to finish the edges. Each step adds work, so ask a qualified installer to check the opening before you buy.

The installation planning guide lists what a pro will check for either type.

Size and fit

An over-the-range microwave has to fit the standard opening above the range, and 30 inches is the most common width in our comparisons. A built-in has its own opening size, so the cabinet is built around the unit.

Measure the space before you choose either one. For an over-the-range unit, check the width, the height and the depth.

For a built-in, check the cabinet bay, the depth behind the opening and the outlet location.

Power and the outlet

Both types plug into a household outlet, and the location matters. An over-the-range unit's outlet sits in the cabinet or wall above the range.

A built-in's outlet sits inside the cabinet opening, so plan it before the cabinet is built. A licensed electrician should confirm the outlet and the circuit for either type.

Cost of the setup

Pricing varies by model and brand, and the total depends on the install. An over-the-range unit may cost less to install in a kitchen that already has a range and a vent path.

A built-in can cost more to install if the kitchen needs new cabinet work, a new outlet or a separate hood. Compare the full setup, not only the microwave, before you decide.

Cleaning and upkeep for each type

An over-the-range unit adds its fan and filter to the cleaning list, so check the manual for the filter schedule. Wipe the interior and the turntable after cooking, as you would with any microwave.

A built-in's cleaning depends on its own filter and on the separate hood. The upkeep is split between two appliances, so plan the cleaning for both.

Mounting and the trim

An over-the-range unit mounts to the wall and cabinet with a bracket and sometimes a filler kit. The bracket has to match the model, and the filler closes the side gaps if the unit is narrower than the opening.

A built-in relies on its trim kit and the cabinet frame for support. Check the trim kit and the cabinet specs before you order, since a mismatch can leave gaps or loose edges.

Who should choose over-the-range

Choose an over-the-range microwave if you have a standard range, a vent path and a need to save counter space. It suits a kitchen where the cooktop needs a fan and the install budget is tighter.

It also suits a renovation that keeps the existing range and hood layout. A qualified installer can swap in a new unit without a major rebuild.

Who should choose built-in

Choose a built-in if you want the wall above the cooktop open and you already plan a separate hood. It suits a kitchen with a wall oven or a tall cabinet bay that's meant for a microwave.

It also suits a remodel where the cabinet layout is still open. You can place the controls at a comfortable height and plan the vent and the outlet together.

Over-the-range microwave vs built-in microwave for a remodel

In a remodel, the built-in is easier to plan around if the cabinets are still on paper. The cutout, the outlet and the hood all go into the same plan.

An over-the-range unit is the simpler choice if the kitchen is staying as it is. It replaces the old unit in the same opening, which keeps the work small.

If you're weighing a countertop unit as well, the over-the-range vs countertop comparison covers that trade-off.

Questions to ask before you choose

A few questions help you decide between the two. Write the answers down before you talk to an installer.

• Does my kitchen already have a vent path over the cooktop?
• Do I want the wall above the range open, or do I need the space for storage?
• Where does the outlet need to go, and does a licensed electrician agree with the plan?

Over-the-range vs built-in microwave: our pick

For most standard kitchens with a range and a vent, an over-the-range microwave is the simpler and more practical pick. It does two jobs in one unit and fits the space above the cooktop.

Pick a built-in when the cabinet plan is still open and a separate hood is already part of the design. Read the complete over-the-range microwave guide for the models that fit a standard opening.

Frequently asked questions

Is a built-in microwave the same as an over-the-range microwave?

No, an over-the-range microwave mounts above the cooktop and includes a fan that vents the range. A built-in fits into a cabinet or wall opening, and most built-in units have no fan, so a separate hood handles the cooktop.

Which one is easier to install, over-the-range or built-in?

Over-the-range is usually the simpler install in a standard kitchen, since it mounts over the existing range and vents through the same path. A built-in needs a cabinet opening, an outlet in the right place and a separate vent, so it is more work for a qualified installer.

Do I need a range hood if I choose a built-in microwave?

Most built-in microwaves don't have a fan, so a range hood is usually needed to vent the cooktop. Ask a qualified installer to confirm the hood and the vent path before you plan the cabinet.
