Built-In Microwaves
Built-in microwaves install flush into your cabinetry using a trim kit, giving a seamless integrated look. Critical measurement is the cabinet cutout, not the microwave's exterior dimensions.
Most premium built-ins require an exact cabinet cutout — measure twice, order once. A misfit at $800+ is a painful return.

What to look for in a built-in microwave
1. Cutout dimensions trump everything
The number that matters is the cabinet opening, not the microwave's outer size. Manufacturer spec sheets list the exact cutout (usually a tolerance of ±⅛"). Cut to that, not the unit's body.
2. Trim kits often sold separately
Many "built-in compatible" countertop models accept a trim kit ($150–300) that gives the flush look. Verify whether the kit is included or a separate purchase before you compare prices.
3. Allow for ventilation behind the unit
Built-ins still need airflow. Most require 1–2" of depth behind the rear flange for cooling. A solid back wall traps heat and reduces lifespan.
4. Match the cabinetry depth
Standard wall cabinets are 12" deep; standard base cabinets are 24". Built-in units typically need 22–24" of cabinet depth — check before assuming a wall-cabinet install will work.

Frequently asked: built-in microwaves
What's the difference between built-in and countertop?
Built-in microwaves install flush into cabinetry, requiring an exact cutout and usually a trim kit. They look integrated and free up counter space. Countertop units sit on the counter with clearances around them and are removable.
Do all built-in microwaves need a trim kit?
Most do. The trim kit fills the gap between the unit and the cabinet opening for a flush appearance. Some "true" built-ins (like Bosch and Miele) include the trim. Many countertop-style units that are "built-in compatible" require buying a separate kit ($150–300).
Can I install a built-in microwave myself?
If the cabinet cutout already exists and matches the spec sheet, yes — it's usually a slide-in install with a few mounting screws. Cutting the cabinet itself is where most DIYers get into trouble; even ⅛" off can prevent the unit from sliding in.
What's the standard cutout size for a built-in microwave?
There is no single standard. Common sizes are 24", 27", and 30" wide with heights of 16–22". Each model has its own exact cutout requirement listed in the install manual. Always verify against the specific model.
