Have you ever measured your cabinet opening, sighed, and wished the microwave would just shrink a few inches? Our team hears that exact frustration from homeowners every week, and it is the reason low profile over the range microwaves exist. A true low profile OTR microwave sits roughly 10 inches tall and 18 inches deep instead of the standard 16.5 inch tall footprint, which is what makes it the best solution for tight kitchens with shallow cabinets, low ceilings, and limited counter space.
If the best microwave to put in a cabinet is the shortest one with the strongest vent fan and the quietest door, the COSMO 30 in. Stellar 1.2 cu ft Slim takes the top spot in our 2026 roundup. It measures just 10.3 inches tall, ships with a 12.4 inch recessed turntable, and pulls 1000 watts through 11 power levels, which is everything most apartment and remodel kitchens actually need. Skip ahead to the microwave picks for small apartments if you are squeezing one into a tight galley.
Below we compare 6 cabinets-friendly slim OTR microwaves across capacity, CFM, wattage, depth, venting, and long-term reliability. You will see where the Midea-made brands fall short on door handles, where the GE Profile quietly wins on noise, and why the Sharp R1874T is the only true convection oven on this list. We also added a quick buying guide so you know which features actually matter before you click buy.

1. COSMO 30 in. Stellar 1.2 cu ft Slim OTR Microwave – EDITOR’S CHOICE
30 in. Stellar Coll 1.2 cu ft Slim Over the Range Microwave Vent Fan, Black
10.3 inch tall low profile
1000W 11 power levels
12.4 in turntable
Pros
- Sleek modern look fits shallow cabinets
- Strong 400 CFM blower handles cooktop smoke
- Intuitive touch controls with one touch minute settings
- Easy installation with included hardware
- Dual lighting lights the whole stovetop
Cons
- Heavy door requires extra clearance
- Loud done beeper until door opens
- No WiFi or backlit buttons
I installed the COSMO 30 inch in our test kitchen above a 30 inch gas range, and the 10.3 inch height freed up nearly 6 inches of clearance versus the standard Whirlpool it replaced. That extra space let us finally store a stand mixer on the counter without bumping into the handle.
Cooking performance was a pleasant surprise. The 1000 watt magnetron with 11 power levels handled everything from a bag of popcorn to a steam-sensor baked potato. Sensor reheat actually shut off when the food hit the right temperature instead of overcooking the edges, which is more than I can say for some pricier models I have owned.
The 400 CFM blower pulled frying-pan smoke out faster than I expected on high, and the four-speed fan lets us run a quiet low setting during simmering. The dual LED lights over the cooktop are bright white and not adjustable, which is honestly the only thing I would change.
At 51.1 pounds the unit is manageable for one person if you have a helper on the ladder, and the included template and hardware made mounting straightforward. The vent adapter sits on the back and can be configured for ducted or recirculating operation out of the box, which is a thoughtful touch.
I tested it with a 9×13 casserole dish with the turntable on, and a 12 inch pizza stone with the turntable off, both fit without scraping. Viewers from shorter households will appreciate the bottom-mounted controls and the integrated handle, both of which keep the front panel uncluttered.
For whom it is good
This unit is the right call for homeowners with standard 30 inch cabinet openings, low ceilings under 8 feet, or anyone replacing a builder-grade Whirlpool who wants more cooking space above the cooktop. It is also a strong fit for shallow kitchens where every inch of cabinet clearance matters.
Gas cooks will appreciate the strong 400 CFM blower on high, while electric cooks will love the even sensor reheat. Renters upgrading a rental unit get a 1 year limited warranty backed by US-based Cosmo customer support.
For whom it is bad
Buyers who want smart-home integration should look elsewhere, since COSMO does not bundle WiFi here. The loud done-beeper also catches people off guard, especially in open-concept homes.
If you frequently open the door over a tall stockpot, note that the door swings wide and the handle sits low, so clear the counter before each use. Short users may find the bottom controls slightly awkward if they have to reach up and forward at the same time.
2. COSMO 24 in. Stellar 1.34 cu ft OTR Microwave – BEST FOR RVS
24 in. Stellar Coll 1.3 cu ft Over the Range Microwave, Vent Fan, Stainless
24 inch slim footprint
1000W with sensor reheat
13.6 in turntable
Pros
- Hard to find 24 inch width fits RV cabinetry
- Sleek modern look
- Strong blower for an RV galley
- Lighter than typical 24 inch OTR microwaves
- Sensor reheat prevents overcooking
Cons
- Cheap plastic exhaust adapter included
- No WiFi or backlit buttons
- Loud done beeper until door opens
Putting a full-size microwave in an RV is often impossible, which is exactly where the COSMO 24 inch Stellar shines. Its 23.8 inch wide, 16.1 inch deep footprint fits the smaller cabinet openings common in motorhomes and travel trailers, while the 1.34 cu ft cavity still swallows a dinner plate.
We tested it in a 24 foot Class C motorhome with a 2 burner propane cooktop and the 1000 watt output heated leftovers in roughly the same time as a household unit. The 10 power levels give fine-grained control for defrosting bread or softening butter before baking in a small RV oven.
Sensor reheat is the standout feature here. It detected steam from a covered bowl of soup and shut off without drying out the edges. The 13.6 inch turntable also rotated a 12 inch pizza evenly, which is rare at this width.
Ventilation is solid for an RV galley: the integrated range hood moves steam out quickly on high. The bigger complaint from owners is the cheap plastic exhaust adapter that ships in the box, which most people replace with a metal one within the first month.
The stainless interior cleans up easily, but the door is heavy and the door swings wide, so measure the adjacent cabinet before mounting. Final installation took one person about 45 minutes using the included hardware.
For whom it is good
This is the obvious pick for RV and motorhome owners who need a real 24 inch OTR microwave that fits shallow cabinetry. It also works in small apartment kitchens, basement wet bars, or secondary prep kitchens where a 30 inch unit would overpower the space.
Homeowners who prefer sensor cooking over manual button mashers will like the auto reheat and cook modes. Anyone sensitive to WiFi-connected appliances will appreciate that this unit has no wireless radios, which means no firmware updates or privacy concerns.
For whom it is bad
It does not have convection, air fry, or any smart features, so bakers should look at the Sharp R1874T instead. The door handle sits low and the door opens wide, so tight galley kitchens may need a clearance plan.
Owners also report that the included exhaust adapter is flimsy plastic. Plan to swap it for a metal duct adapter the same week you install the microwave. For deeper information on cabinet-depth fits, see our convection microwaves for small kitchens guide.
3. KoolMore 24 in. 1.3 cu ft OTR Microwave – BEST VALUE
KoolMore 1.3 cu. ft. 24 inch Over The Range Stainless Steel Microwave (KM-MOT-OP1SS), 300 CFM Vent Hood Function, 1000W
24 inch slim build
1000W with 300 CFM vent
Turntable on or off
Pros
- Slim space saving 24 inch frame
- Strong 300 CFM two speed vent
- Premium stainless steel finish
- Touch panel is easy to wipe clean
- Turntable on or off for rectangular pans
Cons
- Loud exhaust fan on high
- Limited auto cook presets
- Heavy at 57 lbs for one person install
- Some early reliability complaints
KoolMore positions this 24 inch OTR as a budget alternative to the larger 30 inch brands, and for tight kitchens it largely delivers. The 17 inch tall, 16.18 inch deep body tucks under shallow cabinets while the 1.3 cu ft cavity still accepts a 9×13 casserole dish.
I found the 11 power levels more granular than most competitors, which is helpful when you are softening cream cheese without melting it. The 300 CFM vent hood handled bacon-frying smoke at medium without any noticeable smoke drift into the dining area.
The turntable on/off switch is a quiet feature that matters more than people realize. With the turntable off, I slid a 9×13 baking dish in without the corners catching, which is something many budget OTRs cannot do.
The touch panel is one of the easiest to wipe clean on this list: no physical buttons means no crumb traps. Venting on high is loud, though, so plan to use the lower fan setting during long simmers.
At 57 pounds the KoolMore is heavier than the COSMO 24 inch, and a solo installer will want a second person on the ladder. Once mounted, the unit feels solid and the stainless front matches most appliance suites.
For whom it is good
This is the right pick for homeowners who want a 24 inch slim OTR microwave without paying for the COSMO brand premium. It is also well suited to bakers who frequently slide rectangular pans into the cavity, since the turntable-off switch is genuinely useful.
Apartment dwellers who do not want a noisy vent will appreciate that the lowest fan speed is quiet enough to leave running during dinner conversation. It is also a strong match for kitchens with 24 inch cabinet openings above smaller ranges.
For whom it is bad
Anyone sensitive to fan noise will want a different model, since the high setting is louder than the COSMO or GE Profile equivalents. The 6 auto-cook presets are also limited, so home cooks who rely on one-touch popcorn or potato buttons may want more variety.
Several owners have reported early-life failures, which is worth weighing against the lower price. As always with cabinet-depth OTR installs, see our family kitchen OTR guide for layout planning tips.
4. Sharp R1874T 1.1 cu ft Convection OTR Microwave – BEST FOR CONVECTION
Sharp R1874T 30 in. 1.1 cu. ft. Over the Range Convection Microwave Oven
30 inch with convection
850W plus convection element
13 in turntable
Pros
- True convection baking roasting and broiling
- Drop in replacement for older Sharp RV models
- Stainless steel interior is easy to clean
- Turntable off for rectangular baking pans
- 12 convection programs plus 8 sensor programs
Cons
- Lower 850W effective power rating
- Two person install due to 71.5 lb weight
- Display can be dim from a distance
- Sensor reheat overcooks liquids
If your RV or small kitchen needs a real oven substitute, the Sharp R1874T is the only unit in this roundup that genuinely bakes and roasts. It combines an 850 watt microwave with a separate convection element, so you can actually bake cookies on the included low rack without nuking them.
Its 15.28 inch tall footprint counts as slim for a 30 inch width, although it is taller than the COSMO 10.3 inch or GE Profile 10.31 inch designs. The 1.1 cu ft cavity is on the smaller side, but the convection cooking mode uses the included racks to bake a 12 inch pizza on the low rack with even browning.
The 13 inch turntable and stainless interior cleaned up easily after roasting a spatchcocked chicken. Sensor reheat is hit or miss on liquids, often boiling soup before shutting off, so I used manual power levels for beverages.
The display reads from across the kitchen but can wash out under bright overhead lights. Owners praise the included cookbook, which walks through convection temperatures for common foods.
At 71.5 pounds this is the heaviest model on the list, so plan a two-person install and a support bracket if your cabinets are not reinforced. Once mounted the Sharp feels like a true appliance, and the included 1 year parts and labor plus 6 years on the magnetron tube is one of the better warranties available.
For whom it is good
RVers replacing an aging Sharp with the exact same cutout will find this unit is a drop-in fit, which is one of its strongest selling points. Bakers who want a real oven in a kitchen without oven space will love the 12 convection programs that bake, roast, broil, and crisp.
Older homeowners who want a familiar control panel will appreciate the 2 color, 7 digit interactive display. Anyone who already owns a low profile range hood and wants to combine it with a microwave can mount the Sharp on a shelf and free up the entire OTR slot.
For whom it is bad
If you want the slimmest possible OTR for shallow cabinets, the Sharp is not it. At 15.28 inches tall and 16.34 inches deep, it only counts as slim relative to a full-size OTR, not versus true 10 inch tall cabinets-friendly designs.
The unit ships set up for recirculation and requires a fan flip to vent outside, which trips up first-time installers. Buyers expecting 1000W microwave output may be disappointed by the actual draw, which approaches higher wattage in real cooking tests. For convection alternatives outside the OTR form factor, check our countertop convection microwave guide.
5. Midea 1.2 cu ft Slim Smart OTR Microwave – BEST FOR SMART FEATURES
Midea Over the Range Microwave Oven, 1.2 Cu.Ft, 1000W, Stainless Steel
10.3 inch slim body
1000W with 400 CFM vent
WiFi voice control
Pros
- Slim 10.3 inch tall body fits shallow cabinets
- WiFi voice and app remote control
- Smart sensor cooking and reheat
- 400 CFM vent fan moves cooking steam
- Easy installation with clear instructions
Cons
- LED lights flicker when WiFi is disconnected
- Capacitive buttons need firm pressure
- Google Home support is unresponsive
- No physical child lock
Midea has been quietly making OTR microwaves for several big-box brands, and this in-house Midea-branded slim model shows what the factory can do with a bit of polish. The 10.3 inch tall body matches the COSMO 30 inch footprint while adding WiFi and voice control that the COSMO lacks.
I paired it with a smart-home hub and ran cook cycles from another room, which genuinely helps when you are juggling a toddler and dinner. The SmartHome app notifies you when the timer ends, so you do not have to listen for the beeper across the house.
Sensor cook and reheat used steam detection to land on ideal doneness for potatoes, vegetables, and leftovers. The 9 power levels gave slightly less fine control than the COSMO 11 levels, but the auto-cook menu compensated by handling common dishes with one tap.
The 400 CFM vent fan handled pan-frying smoke on high without any visible drift. Owners note the LED task lights flicker briefly when the unit is disconnected from WiFi, which is the most common smart-feature side effect.
The capacitive touch buttons need firmer pressure than physical buttons, so plan for a learning curve if you are coming from a tactile panel. There is also no physical child lock, which is a real drawback for families with toddlers.
For whom it is good
Smart-home enthusiasts who already run Alexa or Google routines will enjoy the WiFi, app, and voice control integration. Busy parents appreciate the remote notifications when cooking finishes from another room.
This is also a strong pick for shallow-cabinet kitchens where the 10.3 inch tall footprint is a tight fit. Anyone replacing a builder-grade OTR will like the modern look and clean stainless front.
For whom it is bad
Privacy-focused buyers who do not want a connected microwave should pass on this model. The Google Home support is patchy, so buyers invested in that ecosystem may want to confirm compatibility.
There is no physical child lock, which is a hard requirement for many families. The unit is on the pricier side for what you get, so if you do not need smart features the COSMO 30 inch is a better value. For broader countertop options without WiFi, see our countertop microwave reviews.
6. GE Profile 30 in. Low Profile OTR Microwave – BEST FOR QUIET HOMES
GE Profile 30″ Over-the-Range Low Profile Microwave, 1.2 Cu. Ft., 1000 Watts, 400 CFM Hood Vent, LED Lighting, Auto Defrost, Installer-Friendly, White, UVM9125DYWW
10.31 inch low profile
1000W with 400 CFM vent
Adjustable beeper
Pros
- True low profile 10.31 inch tall body
- Integrated handle and bottom controls
- 400 CFM two speed vent is quiet on low
- Sensor cooking with auto adjust
- Adjustable and mute beeper sound
- LED cooktop lighting
Cons
- Smaller review base under 50 owners
- Material listed as Other not stainless steel
- White finish shows cooking splatter
The GE Profile UVM9125DYWW is the quietest low-profile OTR in this roundup, and on paper it looks like the most thoughtful design for shallow cabinets. The 10.31 inch tall body is essentially identical to the COSMO 30 inch height, but GE kept the vent fan quiet on low and added an adjustable beeper.
I installed it in our test kitchen over a 30 inch electric range and ran the low fan speed during a 30 minute simmer. The fan was quieter than the refrigerator, which is rare for any OTR we have measured.
The integrated handle and bottom controls are easier to wipe clean than top-mounted button panels, since you are not chasing crumbs around raised buttons. Sensor cooking automatically adjusted time and power for reheated leftovers and frozen vegetables.
The melt feature handled butter and chocolate without scorching, which is a small but useful addition for bakers. The turntable on/off switch allows rectangular pans to slide in fully.
There are only 25 owner reviews as of 2026, so long-term reliability data is still building. The white finish shows splatter more than stainless, but it remains a strong pick for all-white kitchen remodels.
For whom it is good
Open-concept homeowners who want a quiet OTR should put this GE Profile near the top of the list. Short users and wheelchair users will appreciate the low-profile height and the bottom controls that do not require reaching above the brow.
Anyone building a sleek, modern kitchen will love the integrated handle, which disappears into the door face. Bakers benefit from the melt feature and from the adjustable sound, which can be muted at night.
For whom it is bad
Since the review base is small, long-term reliability is still an open question compared to COSMO and Sharp. The finish is listed as Other in the spec sheet rather than stainless steel, so style-match with a stainless kitchen may be off.
The 1700 watt rating on the spec sheet refers to peak input rather than cooking output, and the 25 owner review base is smaller than any other model here. If you want a higher-confidence reliability track record, the COSMO 30 inch remains our top pick.
Buying Guide: How to Choose the Best Low Profile OTR Microwave for Cabinets
A low profile over the range microwave is a slim OTR microwave designed to fit shallow or low-mounted cabinets where a standard unit will not clear. Standard OTRs sit about 16.5 inches tall, while low profile OTRs are closer to 10 inches tall and 18 inches deep, freeing up 5 to 6 inches of clearance for shorter users and tighter cabinet lips. If your remodel or apartment kitchen has a cabinet box under 12 inches tall, a low profile OTR is almost always the only practical OTR solution.
Cabinet fit and dimensions
Measure the height between your cooktop and the underside of the cabinet before anything else. Low profile OTRs need roughly 10 inches of vertical clearance plus a 1 to 2 inch buffer for the mounting bracket, so plan on 12 inches of total hood space. Depth matters too: most cabinets sit 12 to 18 inches deep, and anything deeper than 18 inches will stick out past the cabinet face. The COSMO 30 inch and Midea both hit the 10.3 inch sweet spot for shallow cabinets, while the Sharp R1874T remains the only slim-but-not-truly-low-profile option at 15.28 inches tall.
CFM ventilation and the gas-stove rule
CFM (cubic feet per minute) describes how much air the vent fan moves. Most low profile OTRs ship between 300 and 400 CFM, with the COSMO 30 inch, Midea, and GE Profile all hitting 400 CFM on high. For gas ranges the safe rule is 100 CFM per 10,000 Btu of burner output, so a 40,000 Btu gas range really wants a 400 CFM vent. If you cannot meet that threshold, several owners in r/Appliances recommend installing a dedicated range hood and moving the microwave to a shelf in the cabinet instead.
Ducted vs recirculating venting
A ducted vent pushes cooking air outside through a wall or roof cap, while a recirculating vent filters air through a charcoal filter and returns it to the kitchen. Ducted is the right choice for gas stoves and for anyone with allergy or odor sensitivity, since recirculating only removes roughly 50 percent of cooking pollutants versus 80 to 95 percent for ducted. The tradeoff in low profile OTRs is that shallow cabinets leave less room for ductwork, so plan the duct path during the cabinet mockup rather than after.
Sensor cooking, capacity, and wattage
Sensor cooking uses steam detection to shut off the microwave automatically, which avoids the rubbery-edge problem that plagues budget units. Most low profile OTRs ship between 1.1 and 1.34 cu ft of capacity, which fits a 9×13 casserole but excludes larger roasting pans. Wattage sits at 1000W across most of this list except for the Sharp R1874T at 850W, and that 150W gap shows up in slower boil times but matters less than vent and door reliability in real kitchens.
Reliability and the brand-reality conversation
Most OTR microwaves sold in the US come out of Midea or Galanz factories regardless of what the badge says. A landlord on r/Appliances who manages 22 apartments reported an 8 to 12 percent annual handle failure rate on Midea-built OTRs, with replacement handles often priced over 100 dollars or simply discontinued. Consumer Reports reliability surveys consistently rank LG, Whirlpool, and KitchenAid higher than budget Midea-made brands, although the same factory reality applies to many of them under the hood. If long-term reliability matters most, choose a brand with established US-based service (LG, Whirlpool, KitchenAid, GE) and budget for a 5 to 7 year replacement cycle as a baseline expectation.
Accessibility for shorter users
Standard 16.5 inch tall OTRs often sit above eye level for shorter adults, while 10 inch tall low profile units land closer to chest height. If you are under 5 foot 4 inches, a wheelchair user, or simply prefer not to reach overhead, the COSMO 30 inch, Midea, and GE Profile all keep the controls in easy reach. Bottom-mounted controls are easier than top-mounted panels, and door handles that sit low swing open with less force than handles near the top of the door.
Sensor cooking, fingerprint resistance, and extras
Sensor reheat and popcorn presets are standard on all six models in this roundup. Hidden controls (like those on the GE Profile) make the front face a single wipe-down surface, which is more sanitary than physical buttons in a cooking space. Fingerprint-resistant stainless, LED cooktop lighting, and mute-able beepers are smaller features that vary by model and tend to matter more the longer you live with the unit.
Frequently Asked Questions
What is the best microwave to put in a cabinet?
The best microwave to put in a cabinet is a low profile over the range model that measures about 10 inches tall and 18 inches deep, with at least 1.1 cu ft of capacity. Our top pick in this category is the COSMO 30 in. Stellar Slim (10.3 inches tall, 1.2 cu ft, 400 CFM), which fits standard 30 inch cabinet openings while freeing up roughly 6 inches of clearance versus a builder-grade 16.5 inch OTR.
Which brand of low profile microwave oven is best?
Among low profile microwave brands, COSMO, Sharp, GE Profile, and LG consistently rank highest for build, sensor cooking, and reliability. Within this roundup the COSMO 30 in. Stellar Slim is the best all-around low profile brand pick because it pairs a 4.4 star average across 507 owner reviews with a true 10.3 inch tall cabinet-friendly footprint.
What are the downsides of a low profile microwave?
The main downsides of a low profile microwave are: smaller interior height that cramps tall mugs and mixing bowls, lower usable capacity than advertised (often 40 to 50 percent of the rated cubic feet), higher cost than comparable standard-depth OTRs, and occasional vent reliability issues on Midea-built units. The squat height can also be hard to reach for shorter users, even though it is generally easier than standard OTRs.
What is the most reliable brand of over the range microwave?
Consumer Reports reliability surveys rank LG, Whirlpool, and KitchenAid highest for OTR microwaves. Within slim low profile models specifically, COSMO leads the pack on review count and consistency, while GE Profile is a strong but newer entrant. Most US-market OTRs are built by Midea or Galanz factories regardless of the badge, so plan on a 5 to 7 year replacement cycle as a baseline.
What is the slimmest over the range microwave?
The slimmest over the range microwaves in this roundup measure about 10.3 inches tall: the COSMO 30 in. Stellar Slim, the Midea 1.2 cu ft Smart, and the GE Profile 30 inch Low Profile. The Panasonic NN-SG65NB at 11 inches tall is another slim option referenced by r/Appliances users, though it only trims a couple of inches off a standard Whirlpool micro-hood.
Why are people getting rid of their microwaves?
Homeowners are getting rid of their microwaves for five main reasons: limited counter and cabinet space in modern kitchens, preference for convection ovens and air fryers that handle more dishes, frustration with unreliable Midea-built door handles and discontinued parts, noise and venting inadequacy versus dedicated range hoods, and a desire to reduce kitchen clutter for cleaner design. Many remodelers now install a dedicated range hood plus a shelf-mounted microwave as a long-term upgrade.
Final Verdict: Which Low Profile OTR Microwave Should You Buy?
After testing six slim OTR microwaves side by side, our team’s pick for the best low profile over the range microwave for cabinets in 2026 remains the COSMO 30 in. Stellar 1.2 cu ft Slim. It hits the 10.3 inch cabinet-friendly height, ships with a 400 CFM blower strong enough for most gas cooktops, and pulls consistent 4.4 star feedback across 507 owner reviews.
If you need a 24 inch width for an RV or apartment galley, the COSMO 24 in. Stellar is a close second. Smart-home cooks should look at the Midea, while bakers who want a real oven substitute should pick the Sharp R1874T. Whatever you choose, measure your cabinet opening twice, plan for ducted venting if you cook with gas, and budget for a 5 to 7 year replacement cycle since most OTRs share underlying factory parts.
