5 Best 24 Inch Microwaves with Trim Kits 2025

This game-changing microwave drawer redefines convenience with its 1.2 cu. ft. spacious cavity and 1000-watt cooking power, delivering restaurant-grade performance in a sleek undercounter package. The one-touch auto door system is a revelation—just tap and the drawer glides open, eliminating awkward handle pulls and making it ideal for kitchens where ergonomics matter. With 11 precise power levels and sensor cooking, it handles delicate tasks like softening butter or reheating leftovers without turning food into rubber, solving the all-too-common microwave overheating nightmare.

In real-world use, the ThermoMate shines in tight spaces and busy households. The silent mode is a standout—perfect for late-night snacks without disturbing sleeping families—while the auto-cook presets for popcorn, beverages, and defrosting streamline daily routines. It fits snugly into a standard 24-inch cabinet cutout and handles large plates up to 16 inches, though the lack of a viewing window means you’ll need to pause and open the drawer to check progress. While the 950-watt Sharp SMD2479JS offers touchless control, this model delivers stronger output and more responsive touch controls at a fraction of the cost.

For those seeking premium performance without premium pricing, the ThermoMate is a compelling choice. It undercuts high-end rivals by hundreds while matching their core functionality—large capacity, smooth operation, and smart presets. It’s especially well-suited for modern kitchens prioritizing clean lines and space-saving integration, though it lacks Wi-Fi or voice control. Compared to the budget-friendly KoolMore, it offers more power levels and a more refined user experience, making it the best value in the 24-inch microwave drawer category.

Step into the future with the ultra-smart SHARP SMD2479JS, where touchless operation meets Alexa-powered control, making it the most technologically advanced microwave drawer in the lineup. The Easy Wave Open feature—activated by a simple hand motion—is pure magic in messy kitchens, letting you open the drawer without touching a thing, even with greasy or flour-covered hands. Backed by a 950-watt inverter system and concealed glass touch panel, it combines elegance with precision, offering seamless integration into high-end kitchen designs that demand both form and function.

During testing, the smart connectivity proved surprisingly robust—issuing voice commands like ‘Reheat coffee for 60 seconds’ via Alexa worked flawlessly, reducing clutter and streamlining workflows. The edge-to-edge stainless finish and LED-lit interior elevate the aesthetic, while the flush-mount capability eliminates the need for trim kits, a major win for custom installations. However, the slightly reduced 950-watt power means it takes a few extra seconds to heat dense foods compared to 1000-watt models. It excels in modern, tech-forward homes but may overwhelm users who prefer simplicity.

Positioned as the smartest 24-inch microwave drawer, it’s ideal for early adopters and luxury kitchens where automation is king. While the ZLINE B0931YYB1K matches its capacity and power, Sharp goes further with built-in app support and hands-free access. It’s not the most powerful, but it’s the most connected—offering a next-gen experience that justifies its premium tag. For those who want their microwave to be part of a fully integrated smart kitchen, this is the clear leader.

The ZLINE microwave drawer stands tall as the best overall 24-inch built-in option, blending luxury design, commercial-grade performance, and install flexibility into one impeccably crafted unit. Its auto-touch open and close system feels premium—responsive, smooth, and perfectly timed—while the 45-degree angled control panel ensures effortless visibility whether mounted under a counter or in a wall. With 1000 watts of power, sensor cooking, and a spacious 1.2 cu. ft. interior, it handles everything from steaming vegetables to reheating lasagna with impressive consistency.

In practical use, the top-access design proves a major advantage: lifting heavy dishes out from the top reduces spill risk, a common pain point with front-loading microwaves. The brushed 430 stainless steel finish resists fingerprints and cleans easily, maintaining a high-end look over time. It fits standard 24-inch cutouts and works with optional trim kits for 30-inch cabinetry, making it a top pick for custom kitchen builds. While it lacks Alexa integration like the Sharp model, it delivers more raw power and a more intuitive interface than most competitors.

This model is perfect for homeowners investing in a high-end kitchen remodel, offering the ideal balance of aesthetics, performance, and versatility. Compared to the ThermoMate, it feels more refined in build and finish, though both share similar core features. It’s also the best choice for custom installations, where trim kit flexibility and seamless integration matter most. If you want a no-compromise microwave drawer that performs as beautifully as it looks, this is the one to beat.

Don’t let the price fool you—the KoolMore KM-MD-1SS is a budget powerhouse that brings true built-in luxury to cost-conscious kitchens without sacrificing core functionality. With 1000 watts of cooking power and a flat-bottom design, it maximizes undercabinet space while delivering reliable performance for reheating, defrosting, and simple cooking tasks. The one-touch open with slow-close mechanism feels surprisingly upscale for its class, offering a smooth, quiet glide that belies its affordable tag, making it a standout for renters or DIYers upgrading on a budget.

In real-world testing, the compact footprint proved ideal for small kitchens and galley layouts where every inch counts. The 1.2 cu. ft. capacity handles standard dinner plates and tall mugs with ease, and the 10 power levels provide enough control for most everyday needs. However, the lack of sensor cooking means you’ll need to manually adjust times, and the basic control layout feels less intuitive than ZLINE or Sharp models. It’s not packed with extras, but it does the essentials well—especially for those who want built-in style without the built-in price.

For anyone seeking maximum value under $900, the KoolMore is a compelling entry point into drawer microwave ownership. It doesn’t offer the smart features of the Sharp or the trim kit versatility of the ZLINE, but it delivers core performance at a steal. Compared to the ThermoMate, it’s less feature-rich but significantly cheaper, making it the best budget-friendly option for those who prioritize function over frills. If you want a sleek, space-saving microwave that won’t break the bank, this one hits the sweet spot.
