7 Best Built In Microwaves With Trim Kit 2025 in the United States

The Frigidaire Gallery Series GMBS3068BF is a solid choice for those looking to integrate a built-in microwave into their kitchen. With a capacity of 2.2 cu. ft., it offers ample space for cooking larger meals or multiple dishes at once—ideal for families or anyone who enjoys cooking. Its 1100 watts of power ensures efficient heating and cooking, while the sensor cooking feature automatically adjusts the power levels and time for optimal results, which is great for users who prefer convenience in their meal prep.

The microwave's trim kit compatibility is a strong point, allowing customization with either a 27" or 30" trim kit, although these are sold separately. This adds flexibility in installation, accommodating various kitchen layouts. The stainless steel finish not only contributes to its modern aesthetic but also makes cleaning easier.

Potential drawbacks include the additional purchase of the trim kit, which may not be budget-friendly for all consumers. Furthermore, while the control panel is user-friendly, some users may find it lacks advanced features, like smart technology integration, which is becoming more common in modern appliances. Additionally, its built-in design means it will require proper installation, potentially making it less appealing for renters or those who want a more portable option.

The convection feature helps reduce cooking time by about 20%, providing more even heating through top and bottom elements and a fan system, which improves baking results compared to standard microwaves.

The stainless steel finish and touch control LCD display contribute to a modern look and easy operation, though some users might prefer physical buttons for tactile feedback.

The reinforced door hinges are sturdy enough to hold heavy cookware safely.

However, at 89 pounds, it is quite heavy, and its dimensions require sufficient kitchen space for installation. While it is marketed as a countertop model, it includes a trim kit for built-in installation, which may be slightly complex for those without experience in appliance installation.
