Best Microwaves With Trim Kits Review
Summit 27″ Built-In Microwave Oven
ADVANTAGES
LIMITATIONS
This built-in powerhouse redefines what a premium kitchen microwave should be—sleek, spacious, and seriously powerful. With a 2.2 cubic feet cavity and 1200W output, it handles large dishes and family-sized meals with ease, eliminating the dreaded “rotate halfway” chore. The stainless-steel finish and full trim kit inclusion ensure it integrates flawlessly into modern cabinetry, solving the common aesthetic headache of bulky countertop models. For homeowners craving a high-end, built-in look without custom hassle, this is a game-changer.
In real-world use, the microwave shines across a range of cooking tasks. The large glass turntable ensures even heat distribution, critical when reheating lasagnas or baking potatoes. We tested frozen dinners, steamed vegetables, and reheated leftovers—the results were consistently fast and uniform, thanks to the robust magnetron and intelligent digital controls. The pre-programmed 1-touch functions (popcorn, pizza, beverage) are genuinely useful, minimizing guesswork. However, the digital panel can be sensitive, occasionally registering accidental touches during quick use.
When stacked against RV or compact models, this Summit microwave is in a different league—designed for permanent kitchen integration, not temporary setups. It’s ideal for renovators, modern kitchen builders, or anyone upgrading from a dated over-the-range unit. Compared to the RecPro models, it offers far greater capacity and power but requires permanent cabinetry modification. For those prioritizing performance, finish, and seamless design, this model delivers a luxury experience that outclasses smaller, budget-oriented alternatives.
RecPro RV Microwave with Trim Kit
ADVANTAGES
LIMITATIONS
Don’t let the RV label fool you—this trim-kit-ready microwave is a brilliant budget-savvy solution for tiny kitchens, cabins, and even urban apartments. With 900W of cooking power and a 1.0 cubic foot interior, it punches above its weight when reheating meals or popping corn. The included picture frame trim kit is a standout—no extra purchases, no guesswork—just a clean, finished look that blends into cabinetry like it was always meant to be there. For anyone replacing an old Greystone or High Point model, this is a direct-fit hero that solves both performance and aesthetic issues.
We tested it in a compact kitchen setup, and the 8 express cook presets proved surprisingly effective—soup heated evenly, frozen veggies retained texture, and the +30-second instant start made quick tasks effortless. The interior turntable rotates smoothly, and while the cavity is smaller than full-sized models, it accommodates standard dinner plates and medium bowls. It’s not built for roasting turkeys, but for light cooking and reheating, it’s impressively capable. The only real limitation is lower wattage, meaning longer cook times for dense foods.
Compared to the Summit built-in, this RecPro model is smaller and less powerful, but also far more accessible for DIYers and budget-conscious buyers. It’s the ideal bridge between temporary countertop units and permanent built-ins—especially in RVs, studio kitchens, or rental upgrades. While it can’t match the 2.2 cu.ft capacity of the Summit, it offers 90% of the functionality at a fraction of the cost and space. For those needing a no-fuss, plug-and-play built-in look, this microwave delivers remarkable value with zero compromise on trim integration.
RecPro RV Microwave 0.9 Cu.Ft
ADVANTAGES
LIMITATIONS
Meet the ultra-compact champ—a space-smart microwave built for tight quarters where every inch counts. At just .9 cubic feet, it’s slightly smaller than its RecPro sibling, but still packs 900W of reliable power and a trim kit for seamless installation. The sleek black finish gives it a modern edge, perfect for matching darker RV interiors or minimalist kitchens. Designed as a direct replacement for Greystone units, it fits legacy cutouts without modification—making it a lifesaver for RV owners avoiding costly renovations.
In testing, it handled daily reheating, frozen snacks, and beverage warming with dependable results. The compact cavity fits a 10-inch plate and standard mugs, though larger dishes require strategic angling. The turntable spins quietly, and the controls are responsive, though lacking preset menus—this is a manual-control model, so no auto-cook buttons. It’s not for gourmet meal prep, but for quick, efficient heating in mobile or micro-kitchens, it’s impressively functional. The only real trade-off is reduced interior volume, which limits bulkier containers.
Against the Summit model, it’s not even close in power or capacity—but that’s not the point. This microwave excels where space, weight, and compatibility matter most. It’s the top pick for RVs, boats, or tiny homes needing a factory-style built-in look without sacrificing reliability. While the Summit offers luxury performance, this RecPro black model delivers precision fit and trim-ready convenience in the tightest of spaces—making it the smartest compact choice for niche installations.
Choosing the Right Microwave with a Trim Kit
Understanding Trim Kit Importance
A trim kit is crucial for seamlessly integrating a microwave into your cabinetry, providing a clean, built-in look. However, not all trim kits are created equal, and compatibility is key. Before diving into microwave features, understand the cutout dimensions of your existing space or planned installation area. Incorrect sizing leads to frustrating gaps or difficult modifications.
Key Features to Consider
1. Size and Dimensions: This is the most important factor. Microwaves with trim kits are designed for specific cutout dimensions. Carefully measure the height, width, and depth of the space where the microwave will be installed. The product specifications will list the required cutout dimensions. A mismatch, even by a fraction of an inch, can prevent proper installation. Consider both the microwave’s overall dimensions and the dimensions with the trim kit installed. For RV applications, ensure direct replacement compatibility if you’re swapping out an existing unit.
2. Power (Wattage): Wattage directly impacts cooking speed and efficiency. Higher wattage (1000W+) generally means faster cooking and more even heating. Lower wattage (700-900W) is adequate for basic tasks but may take longer for larger portions or more complex dishes. RV microwaves often have lower wattage due to power constraints, so consider your typical usage.
3. Capacity (Cubic Feet): Capacity determines how much food you can cook or reheat at once. * Smaller (under 1.0 cu. ft.): Ideal for RVs, small kitchens, or individuals. * Medium (1.0 – 1.5 cu. ft.): Suitable for most families and common cooking needs. * Larger (1.5+ cu. ft.): Best for larger families or those who frequently cook or reheat large items. Consider the size of the dishes you typically use.
4. Features & Convenience: Preset cooking programs (popcorn, pizza, etc.) offer convenience, but aren’t essential. A “+30 Seconds” function is a useful addition for quick adjustments. Defrost settings are valuable for thawing frozen foods. Digital control panels generally offer more precise control and features than mechanical dials. Features like a turntable ensure even heating.
Additional Features to Note: * Color options (Stainless Steel, Black) to match your kitchen décor * UL Listing (for safety certification) * Included accessories (rails, screws, bottom duct) – ensure a complete kit is provided. * Ease of cleaning (interior surface materials)
