A microwave trim kit is a set of materials that fills in the gaps between a microwave and cabinetry. These materials can match the style of the microwave and enable it to be fully integrated into the structure and design of the cabinets.
Microwave trim kits hold aesthetic appeal, though they require additional installation expense. A trim kit can generally be purchased from the microwave’s manufacturer or a home-improvement store. Some suppliers offer custom microwave trim kits that fit essentially any microwave and cabinet opening. Microwave trim kits also generally feature vents, since the microwave’s built-in vents face into the cabinetry.
