Finding a dishwasher that actually fits a 33-inch height opening without sacrificing capacity, noise levels, or cleaning performance is a specific pain point for kitchens with compact cabinet layouts or those replacing an older compact model. The standard 24-inch models simply won’t fit, leaving you with a narrow selection where one wrong spec can mean a unit that sticks out, leaves dishes wet, or drowns your open-concept kitchen in noise.
I’m Min — the co-founder and writer behind Gadgets Feed. I specialize in analyzing technical specifications and real-world user feedback for major home appliances, spending hours cross-referencing performance metrics like cycle times, decibel ratings, and tub materials to find the units that deliver real value in tight installation spaces.
After digging through specs, customer reviews, and installation requirements, I’ve identified the top performers for the 33 inch height dishwasher category that balance cleaning power, quiet operation, and smart design.
How To Choose The Best 33 Inch Height Dishwasher
Choosing the right compact dishwasher that fits a 33-inch cutout means looking beyond just width and depth. The height restriction narrows your options to units typically 17.5 to 18 inches wide, designed with adjustable legs to fine-tune the final fit. You’ll need to balance cleaning performance, noise level, drying effectiveness, and tub construction to get a machine that lasts.
Measure Twice, Check the Cutout Height
Not all compact dishwashers are created equal when it comes to total height. Many 18-inch models sit around 32.4 to 32.5 inches high with leveling legs fully tightened, but you need clearance for the unit to slide in and for the top panel to align with your countertop. Always measure the rough opening — from floor to underside of the counter — and check the product’s specified maximum height with legs adjusted. A unit like the Midea 18-Inch at 32.4 inches offers more wiggle room than taller alternatives.
Noise Level: Don’t Ignore the Decibel Rating
In smaller kitchens or open-plan living areas, a loud dishwasher disrupts conversation and TV watching. The quietest models in the 33-inch class operate at around 52 dBA, which is roughly as loud as a quiet library — you’ll hear a gentle hum but not a roar. Models above 55 dBA can be intrusive during the wash cycle. Look for “library quiet” claims or verified 52 dBA ratings in the technical specs.
Tub Material Matters for Drying and Durability
Stainless steel tubs are the gold standard in this category because they retain heat better, which improves the drying process and reduces spotting on glassware. A stainless steel tub also resists odors and cracking over time. Hybrid tubs (stainless steel interior with a plastic base) can save money but often result in wetter dishes. Avoid models with fully plastic tubs if you expect the unit to last more than a few years.
Heated Dry vs. Air Dry: The Real Difference
Many compact dishwashers advertise a “heated dry” cycle, but their effectiveness varies. Some use a heating element at the bottom of the tub to actively dry dishes, while others rely on fan-assisted hot air or a sanitize cycle that raises water temperature. If you live in a humid climate or hate towel-drying plastic containers before putting them away, a model with a genuine exposed heating element — like the Frigidaire — will outperform one that just heats the rinse water.

In‑Depth Reviews
1. Frigidaire 18 in. ADA Compact Front Control Dishwasher
The Frigidaire 18-inch compact model fits neatly into a 33-inch height opening thanks to its adjustable legs and 32.5-inch max height, making it a top-tier choice for tight cabinets. It employs a dual spray arm system — one top, one bottom — to ensure every dish, glass, and pot gets hit with pressurized water from multiple angles, which is a clear step above single-spray units in cleaning baked-on residue.
Its National Sanitation Foundation Certified Sanitize cycle pushes the final rinse water to a temperature that kills 99.9% of bacteria, and the heated drying element at the bottom actively evaporates moisture rather than just relying on residual heat. At 52 dBA, it’s quiet enough to run during a phone call, and the ADA-compliant height makes it accessible for wheeled under-counter installations.
Some users noted that the drying coil in newer models is smaller than previous generations, which can leave plastic items damp, but overall the combination of 8 place settings, six cycles (including Heavy Wash and Energy Saver), and a stainless steel interior delivers reliable daily performance. The package includes room-of-choice delivery, saving you the hassle of hauling a 50-pound unit from a truck.
Why it’s great
- Dual spray arm system provides thorough top-to-bottom cleaning
- NSF-certified sanitize cycle for high-temperature hygiene
- Quiet 52 dBA operation suits open layout kitchens
Good to know
- Heated dry element is smaller than older models, may leave plastics damp
- Warranty service via Frigidaire can be slow in some regions
2. KoolMore 18 in. ADA Panel Ready Dishwasher KM-DW1852-PR
The KoolMore KM-DW1852-PR stands apart because of its panel-ready design — the front accepts a custom wood panel that matches your cabinetry, making the dishwasher virtually disappear into your kitchen aesthetic. It’s a full 18-inch built-in unit with a stainless steel interior, 52 dBA noise rating, and dimensions of 32.5 inches tall, which fits the 33-inch height constraint comfortably with room for leveling legs.
Inside, you get two ergonomic racks with pop-up and fold-down tines that let you reconfigure the layout for tall stemware or bulky pots. The slide-out utensil basket sits in the lower rack, and the unit features five wash cycles (Auto, Normal, Heavy, Delicate, Rinse) plus a sanitize option. The heating element at the bottom actively dries dishes, and the low-profile touch controls are easy to use even with wet hands.
A relevant detail for DIY installers: the unit does not come with an outer door panel, so you’ll need to build or source one that fits your cabinet style. Users report that the instructions for attaching the custom panel are minimal, requiring some woodworking skills. Once properly installed, though, the quiet operation and solid cleaning performance make this a favorite for kitchen remodels where aesthetics matter.
Why it’s great
- Panel-ready front blends seamlessly with custom cabinetry
- Stainless steel interior retains heat for better drying
- Quiet 52 dBA motor won’t disrupt the kitchen
Good to know
- No outer door panel included; requires woodworking skills to install
- Some units have reported issues with the upper rack drawer mechanism after a few months
3. Fisher & Paykel DD24SAX9 24″ Drawer Dishwasher
The Fisher & Paykel DD24SAX9 is a unique entry in the 33-inch height dishwasher category because it’s a single-drawer unit that sits at just 16.13 inches tall — well under the 33-inch ceiling. This means you can install it in a 24-inch wide cabinet space that’s far shorter than standard, or even stack two units (sold separately) for a double-drawer setup. Its 45 dBA noise rating makes it the quietest model on this list, quieter than a typical conversation.
Despite its compact size, the drawer holds 7 place settings and includes a full console with 6 wash cycles, including a rapid wash for quick turnaround. The drawer-style design eliminates bending over — just pull open and load at counter height, which is a genuine ergonomic advantage for taller counters or users with back issues.
At a premium price point, you’re paying for the engineering of the drawer mechanism, the whisper-quiet operation, and the ENERGY STAR efficiency. Some buyers have reported receiving units that were clearly repackaged returns, so inspect the packaging carefully upon delivery. The stainless steel interior and robust build quality are excellent, but the final-fit height is so low that you’ll need to build a custom filler panel if the 33-inch opening is taller than the drawer.
Why it’s great
- Exceptionally quiet at 45 dBA — barely audible during operation
- Drawer design eliminates bending for ergonomic loading
- ENERGY STAR rated with low water and energy consumption
Good to know
- Very expensive due to unique drawer mechanism engineering
- 7 place settings is less capacity than most 18-inch built-ins
4. EdgeStar BIDW1802WH 18 Inch Built-In Dishwasher
The EdgeStar BIDW1802WH is a white 18-inch built-in that fits easily into a 33-inch opening at 32.5 inches tall, with 17.6 inches of width making it ideal for replacing a trash compactor or narrow cabinet. It packs 8 place settings and a silverware basket plus cup tray into a stainless steel interior, and the leakage sensor auto-shuts off water flow if a leak is detected — a rare safety feature at this price level that can save your floorboards.
With six wash cycles (Heavy, Normal, ECO, Glass, Rapid, Rinse) and three extra options (Sanitize, Hi Temp, Heated Dry), you get real flexibility. The 52 dBA noise rating matches the quietest competitors, and the stainless steel basket racks feel solid. Users who have owned it for over five years report consistent cleaning performance, though some note that error codes sometimes require an unplug-and-replug reset.
Where this unit really wins is the value proposition — it offers many of the premium features (stainless tub, sanitize cycle, leak detection) at a mid-range price. The drying performance is adequate for overnight unloading, but if you need bone-dry plastic containers immediately after the cycle, you might need to leave the door cracked open for an hour.
Why it’s great
- Integrated leakage sensor prevents water damage disasters
- Stainless steel interior with 8 place settings for a compact frame
- Quiet 52 dBA operation with 6 wash cycles for daily flexibility
Good to know
- Error codes may appear and require a power cycle to clear
- Does not fully dry plastics; best for overnight drying with door open
5. SPT SD-9263SS 18″ Portable Dishwasher
The SPT SD-9263SS is the only portable dishwasher on this list, meaning it sits on casters and hooks up to your kitchen faucet, making it ideal for renters or kitchens where an under-counter cutout doesn’t exist. Despite its freestanding design, it’s still 18 inches wide with a stainless steel tub and fits 8 place settings, so you get solid capacity without permanent installation.
Its stainless steel interior and racks are a step above portable units with plastic tubs, and it features 6 wash programs including a normal cycle that runs quietly. Users report that it cleans as effectively as built-in models from major brands, with dishes coming out hot and spotless. The flip side is that drying is weaker than built-in units — there’s no active venting, so you’ll need to prop the door open after the cycle to let moisture escape.
It uses a standard faucet adapter, though some buyers needed a different one depending on their faucet type. The unit’s pump can handle up to 8 feet of drainage hose, which gives flexibility in placement. At 237 kWh per year, it’s ENERGY STAR efficient, and the white finish blends with most kitchen fixtures. Just be aware that some units lose heating performance after about 6 months, leaving residue on dishes.
Why it’s great
- Portable design with casters requires no permanent installation or plumbing
- Stainless steel tub and racks at a portable price point
- Quiet operation with effective cleaning comparable to built-in models
Good to know
- Drying performance is weak; must manually vent or towel-dry dishes
- Some units lose heating efficiency after 6 months, leaving residue
6. Sharp SDW6504MS 24-Inch Dishwasher
The Sharp SDW6504MS brings a 24-inch footprint, which is wider than the typical 18-inch compact units, but its pocket handle design and adjustable legs let it squeeze into a 33-inch height cutout if your cabinet width accommodates the extra width. The standout feature is the 2-inch height adjustment on the upper rack, allowing you to fit 11-inch tall platters or large mixing bowls on the lower rack without collision.
It operates at a quiet 52 dBA with Library Quiet technology, includes a half-load option to save water on smaller loads, and uses a hybrid tub construction — stainless steel interior walls with a heavy-duty plastic floor. The 12 place settings capacity is generous, and the fold-down tines on both racks let you reconfigure for odd-shaped items. The sanitize cycle reaches high temperatures for hygienic cleaning.
Keep in mind that the 24-inch width may not fit every 33-inch height cabinet, especially if the cabinet is a narrow 18-inch slot. Users mention that dishes don’t always dry completely with the heated dry cycle, and some units have a quality control issue with the bottom spray arm not rotating properly unless snapped into place. Overall, if you have the width, this is a capable performer with flexible racking.
Why it’s great
- 2-inch adjustable upper rack accommodates tall pots and platters
- Library Quiet at 52 dBA is genuinely unobtrusive
- Half-load option saves water and energy on smaller loads
Good to know
- 24-inch width may not fit all 33-inch height compact cabinets
- Some units have bottom spray arm assembly issues from the factory
7. Honeywell 18-Inch Dishwasher
Honeywell’s 18-inch dishwasher brings a stainless steel tub to the mid-range category, offering better heat retention and drying than plastic-tub alternatives. It fits 8 place settings with two racks and a removable cutlery basket, and its 24-hour delay start lets you schedule cycles to run during off-peak utility hours. The push-button controls are straightforward, and the bar handle provides a solid grip.
The six wash programs cover Heavy, Normal, ECO, Glass, Rapid, and Rinse, giving you flexibility for everything from baked-on lasagna to delicate wine glasses. Users report good cleaning performance on caked-on food, and the compact size is praised for small kitchen spaces. At its price point, this is a reliable workhorse for a family of two or three.
There have been some reports of touch button panels becoming unresponsive after a couple of months, and one user described a water valve misassembled from the factory that required internal reversal. Not all units have these issues, but the inconsistency means you should inspect thoroughly on delivery and test immediately. The stainless steel interior is a definite highlight at this tier.
Why it’s great
- Stainless steel tub at a mid-range price improves drying efficiency
- 24-hour delay start helps schedule cycles for off-peak hours
- Compact 18-inch footprint fits narrow 33-inch height cutouts
Good to know
- Some units have touch panel failure after a few months
- Occasional factory assembly defects require manual correction
8. SPT SD-9254SSA 18″ Built-In Dishwasher
The SPT SD-9254SSA is a sibling to the portable model but configured as a built-in unit with a stainless steel tub and a 1-to-24 hour time delay feature. At 18 inches wide, it’s designed for the same 33-inch height installation as other compacts, with a stainless steel finish and full console controls. The digital display shows fault codes if something goes wrong, helping DIY troubleshooters identify issues.
It uses 234 kWh per year, which is ENERGY STAR efficient, and the rinse aid warning indicator reminds you when to refill. The heated dry function is present, though users report that it’s not aggressive — dishes come out clean but often wet, especially plastics. The unit includes a cutlery basket, top-mount brackets, and both inlet and drain hoses, though some plumbers note the installation instructions are poorly written.
Customer experiences vary widely: some call it the best dishwasher they’ve ever used, praising the power wash and spotless results, while others say it absolutely does not dry dishes despite running the heated dry option. The inconsistency suggests possible manufacturing variation. If you get a good unit, the value is excellent for the stainless steel tub and delay features.
Why it’s great
- Stainless steel tub and robust 1-24 hour time delay scheduling
- Fault code display aids DIY troubleshooting without service calls
- ENERGY STAR rated at 234 kWh/year for low electricity use
Good to know
- Drying performance is inconsistent — many users report wet dishes
- Installation instructions are poorly written and lack clarity
9. Midea 18 Inch Built-In Dishwasher
The Midea 18-Inch Built-In dishwasher is one of the most space-efficient options for a 33-inch height cutout, with its 32.4-inch height including adjustable legs, giving you nearly an inch of room to level it beneath the countertop. It’s a slimline design that holds 8 place settings, and the digital control panel with LED display makes cycle selection clear even in dim lighting.
It offers 6 wash programs — Heavy, Normal, ECO, Delicate, Quick, and Rinse — plus Heated Dry, Hi-Temp, and Sanitize functions. The Hi-Temp wash maintains water at 136°F to tackle heavy soil, making it suitable for baby bottles and children’s dinner sets. The stainless steel tub is a nice bonus at this entry-level price, as many budget dishwashers use plastic tubs that stain and retain odors.
Some customers report that this unit cleans and dries as well as more expensive national brands, while others experienced E4 error codes on the first wash and poor customer support from Midea’s offshore team. The inconsistency in quality control is a risk, but if you get a properly assembled unit, it’s a fantastic value. Use only dishwasher-specific detergent — regular dish soap will cause foaming and errors.
Why it’s great
- Compact 32.4-inch height fits easily under 33-inch counters with leveling room
- Heated dry and Hi-Temp wash for better cleaning and drying
- Stainless steel tub at a budget price point
Good to know
- Quality control issues — some units arrive with E4 errors or leaking
- Offshore customer support is difficult to work with for warranty claims
10. AIRMSEN A01 Slim Countertop Dishwasher
The AIRMSEN A01 is a completely different form factor — a countertop dishwasher that sits on your counter at 19.6 inches tall, making it irrelevant for under-counter 33-inch installations but highly relevant if you don’t have a single cabinet slot available. It’s a slim unit at just 14.2 inches deep with a built-in 1.4-gallon water tank that you refill by kettle or faucet, requiring zero plumbing.
This is not for large families — the 16.5-inch interior height limits you to 5 place settings and items up to 11.8 inches long — but for solo living or a couple, it eliminates the daily hand-washing ritual. It uses three high-pressure spray arms and heats water to 167°F for cleaning, followed by auto hot-air drying. The Energy Saver and Delay Start (2-12 hours) are thoughtful touches, and it’s very quiet.
If you need a solution for a kitchen without any cutout space, this is the only option that fits. It comes with a built-in water softener for salt, reducing spotting. The manual fill becomes a small chore, but it uses only about 1.4 gallons per cycle — an 80% water savings compared to handwashing. Just ensure you have 23.5 inches of clearance above the counter for filling the top-mounted tank.
Why it’s great
- No plumbing required — built-in 1.4-gallon water tank for filling via kettle
- Three high-pressure spray arms deliver 360° cleaning coverage
- 167°F high-temp wash with auto hot-air drying for sparkling results
Good to know
- Manual water tank refilling required before each cycle
- Small capacity — only 5 place settings, not for families of 4+
11. Kraus KCA-1102 Stark Sink & Faucet Combo
The Kraus KCA-1102 is not a dishwasher — it’s a 33-inch single-bowl kitchen sink and a commercial-style pull-down faucet combo — but its 33-inch length and 22-inch width make it a relevant pairing for anyone building out a kitchen with a 33-inch height dishwasher. Having a deep, durable sink from Kraus’s Stark series complements your dishwasher by providing ample space for pre-rinsing or soaking large stockpots.
Built from 18-gauge T-304 stainless steel with a satin finish, this sink resists dents and rust far better than thinner 20- or 22-gauge alternatives. The 9-inch depth accommodates large roasting pans, and the sloped bottom with channel grooves ensures water doesn’t pool. The NoiseDefend insulation pads on all sides dampen the clatter of metal on metal, keeping the kitchen quieter during cleanup.
The included pull-down faucet is solid brass with a 1.75 gpm aerator, and the dual-mount design lets you install it as undermount or drop-in. The bottom grid protects the sink floor from scratches. At 18 inches of faucet height, it fits under most standard cabinets. While not a dishwasher, this set completes the kitchen package around your new compact dishwasher, and the lifetime limited warranty on the sink gives peace of mind.
Why it’s great
- 18-gauge T-304 stainless steel is thick, dent-resistant, and durable
- 9-inch deep single bowl fits large pots and baking sheets
- NoiseDefend insulation pads significantly reduce sink noise
Good to know
- Scratches easily if not wiped with a soft cloth — avoid abrasive pads
- Requires a minimum 36-inch cabinet to accommodate the 33-inch sink
