These kits usually consist of a metal or plastic frame that fills the gaps between the microwave and the surrounding cabinetry, providing a seamless and integrated look. Trim kits are a popular alternative to purchasing a dedicated built-in microwave, often offering a more cost-effective solution for upgrading the kitchen’s aesthetic.
The trim kit directly affects the overall depth requirement for the microwave installation. While the microwave itself might have a specific depth, the trim kit adds to that depth, effectively increasing the space needed for the complete built-in setup. Therefore, when considering a trim kit, you need to factor in the additional depth specified by the trim kit manufacturer, in addition to the microwave’s own depth, to ensure it fits properly within your cabinetry. Failing to do so can lead to the microwave protruding from the cabinets or difficulty installing the trim kit itself.
What other dimensions besides depth should I consider when choosing a built-in microwave?
Besides depth, you should carefully consider the width and height of the built-in microwave. Width is crucial for ensuring the microwave fits snugly within the horizontal space of your cabinetry or trim kit. Similarly, the height must align with the vertical opening to avoid any gaps or structural interference. Accurate measurements of these three dimensions are essential for a successful installation.
Beyond these external dimensions, also consider the interior dimensions, specifically the cubic footage. This determines the microwave’s capacity and its ability to accommodate larger dishes or cookware. Evaluate your typical cooking needs to ensure the internal capacity is sufficient. Additionally, check the turntable diameter, as this impacts the maximum size of plates or containers that can rotate freely inside the microwave. Balancing external fit with internal capacity is key to choosing the right built-in microwave.
Where can I find the depth specification of a built-in microwave?
The depth specification of a built-in microwave is typically found in several key locations. The most reliable source is the manufacturer’s official website. Product pages usually include detailed specifications, including depth, width, height, and other relevant measurements. These specifications are often presented in both inches and millimeters for convenience. In addition, the user manual or installation guide, usually available for download on the manufacturer’s website, contains this information.
Another place to find the depth specification is on the product packaging or a sticker directly on the microwave itself. Retailers often list dimensions on their websites or in-store displays. However, always cross-reference this information with the manufacturer’s official data to ensure accuracy, as retailer specifications can sometimes contain errors. Consulting the manufacturer’s documentation guarantees you have the correct depth measurement before making a purchase and proceeding with installation.
What happens if the built-in microwave is too deep for my cabinets?
If a built-in microwave is too deep for your cabinets, it will likely protrude from the cabinet face, creating an unappealing aesthetic. This protrusion not only looks awkward but can also be a safety hazard, especially in high-traffic areas of the kitchen. Furthermore, it can obstruct the opening and closing of adjacent cabinets or drawers, causing inconvenience and potential damage to your cabinetry.
To rectify this situation, you have several options. Firstly, consider returning the microwave if possible and selecting a model with a more suitable depth. Alternatively, if feasible, you might modify the existing cabinet to increase its internal depth, although this is typically a complex and expensive undertaking requiring professional carpentry skills. Finally, explore using a different installation method, such as a trim kit that allows for slight adjustments in depth, although this might not completely resolve the issue if the depth discrepancy is significant. Choosing a different microwave model with correct dimensions remains the simplest solution.
