The placement of an over-the-stove microwave can vary based on personal preference and the specific design of your kitchen. Generally, there are two common options:
Flush installation: Some homeowners prefer to have the microwave installed flush with the top cabinets. This creates a seamless, built-in look and can be a desirable aesthetic choice, especially if the microwave matches the surrounding cabinetry.
Extended installation: Alternatively, others choose to have the microwave extend slightly beyond the cabinets. This is often done to provide better access to the controls and to allow for easier use of the microwave.
Both options are acceptable, and it ultimately comes down to your personal preference and the style you want to achieve in your kitchen. If you find that your builder has installed the microwave flush with the top cabinets and you prefer it to stick out a few inches, you can discuss this with them and see if it's possible to make the adjustment. Keep in mind that any changes may involve additional modifications to the cabinet structure or require professional assistance.
It's always a good idea to consult with your builder or a kitchen design professional to discuss your preferences and ensure that the microwave placement aligns with your vision for your kitchen.
