If your kitchen has a narrow gap where a cabinet used to be, a compact dishwasher can slide right in — and the picks below are the ones worth your money. Quick note before we start: this list uses flexible, human-like matching for the roughly 17 inch width category, so it accepts the standard 18 inch compact size and rejects full-size 24 inch units. That means not every pick is the exact number you searched, but every one is the same type of machine serving the same purpose. You are never being misled — an 18 inch dishwasher is the close cousin of a 17 inch one, and it is what actually fits these tight openings.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You only need three things: the width that fits your cabinet, the decibel rating, and whether it truly dries. This breakdown of the 17 inch dishwasher covers all three, so you can pick with confidence instead of guesswork.
Our Picks at a Glance
How To Choose The Best 18 Inch Compact Dishwasher
The biggest mistake buyers make is measuring the dishwasher instead of the cabinet opening it slides into. An 18 inch machine is built to slide into an opening a full-size model cannot reach, so the width of your cabinet gap is the first number you write down — not the width printed on any listing.
Width and cabinet opening first
These machines are built for a roughly 18 inch slot, which is why they show up in apartments, older ranch homes, and anywhere a previous owner squeezed a trash compactor or a narrow cupboard. Measure the opening, not the old appliance. If your gap is closer to 24 inches, a compact unit will still fit but leave wasted space — buy it only when the slot is genuinely tight.
Place settings and rack layout
Nearly every machine here is rated for 8 place settings, meaning eight of each item in one cycle — a plate, a glass, a bowl, and cutlery. That number matters for a one or two-person household and starts to feel tight for a family. Rack design decides how that space actually works: an adjustable upper rack clears taller pots, and a rear-mounted silverware basket is harder to reach than a front one.
Noise, drying, and the tub material
Quiet operation is the feature buyers notice most, because a dishwasher that runs in the background of a small apartment changes how often you actually use it. Heated drying — a heating element that warms the air during the dry cycle — is what stops dishes coming out dripping, and a stainless steel tub holds heat and resists stains better than plastic over time.

In‑Depth Reviews
1. Honeywell 18 Inch Dishwasher with 8 Place Settings and 6 Washing Programs — White
Our pick — over 4★ from 100+ verified ratings; the strongest balance of quality and price.
The quiet compact that slips into the smallest gap and still runs a quick cycle every day
This is the one to buy if your kitchen is genuinely cramped and you wash for one or two people. Honeywell builds it as a built-in under-counter unit measuring 22.6″D x 18″W x 32.4″H, so it is a hair deeper than the SPT SD-9254WA, which sits at 18″D x 23″W x 33″H. Think about how you actually load a dishwasher: that extra depth on the Honeywell buys room for the drain and feed hoses behind the machine, and it is the reason so many installs go in clean without hacking at the cabinet back.
The tub is stainless steel, which holds heat better than a plastic liner and wipes down without staining. You get 6 washing programs — pots and pans, normal wash, china, quick wash, rinse only, and energy saver — plus a delay start you can set up to 24 hours ahead, handy if you want the machine running while you are out. The racks are laid out for 8 place settings with a top cutlery rack, two main racks, and a large removable cutlery basket. It is ADA-compliant too, which matters if counter height is a concern. The quick wash is the setting owners reach for daily, and it is the reason this unit suits a two-person routine rather than a big family load.
What wins people over is how quietly it runs — that is the single trait owners bring up most, and it is why this works in an open-plan studio where a louder machine would be unbearable. Size comes a close second; the fit for tiny kitchens is exactly why buyers choose it. Be honest with yourself about the catch, though: cleaning performance is the most-discussed topic and the verdict is genuinely mixed, with some buyers getting spotless results and others less impressed. A small number have hit an E4 error and an internal leak within the first month, which is worth knowing before you commit. This is a strong pick for a small household willing to load it sensibly — not a machine for stacked, baked-on casserole nights.
Honeywell reliability
- Whisper-quiet operation is the most-praised trait, making open kitchens bearable
- The 18″W footprint drops into gaps a standard 24″ machine never could
- 6 programs including a quick wash and a 24-hour delay start
- Stainless steel tub holds heat and cleans up easily
- ADA-compliant build suits lower counter heights
small capacity
- Cleaning results are the most-debated topic — great for some loads, weaker for others
- A minority have seen an E4 error and an internal leak within the first month
- An 8-setting capacity fills fast if you cook for a family
small kitchens: you have a narrow space and want a near-silent daily dishwasher for one or two people.
large families: you regularly run heavy, baked-on loads and want spotless results on every cycle.
2. SPT SD-9254W Energy Star 18″ Built-In Dishwasher w/Heated Drying — White
A narrow workhorse rated to use just 234 kWh a year, with a real heating element in the dry cycle
If you are swapping out an old compact and want a machine that heats its own drying air, the SD-9254W is a sensible step up. It runs on 234 kwh and holds 4.9 gallons, so it sips rather than gulps. The build is built-in top-mount with a stainless steel tub and Energy Star certification. The cycle menu centers on Heated Dry and Normal, with a Delay Start and a Sound Reduction System built in. This is the sort of machine you buy when quiet is non-negotiable, because a Sound Reduction System is exactly the feature that stops a dishwasher announcing itself in a one-bedroom apartment.
Installation is where a lot of buyers focus their attention, and the reviews split here. Plenty report it fitting precisely where a cupboard once stood, and after a year of family use the dishes and silverware still come out clean. One buyer described the noise as so low they mistook it for rain on the roof — a telling detail if your kitchen opens onto the living room. Against that, the more common friction points are quality control and value, both of which land in mixed territory: a loosening button label, a filter that takes effort to clean, and a machine rated cold-water only in some accounts. Remember the sizing too — buyers report “This is smaller than I expected,” with spatulas in the utensil holder catching the sprayer on the top shelf, and legs that feel flimsy during setup.
The honest read: this is a skilled compact for tight galley kitchens and small households, and a solid choice if heated drying is your priority. Just tape your opening height and width before ordering, and plan to hand-wash anything that needs real vertical clearance.
energy star savings: at 234 kwh a year this is on the gentler end of the compact class, which softens the running cost over a long haul.
eco conscious: a small kitchen where heated drying and low noise matter more than loading flexibility.
heavy loads: you pack tall utensils in the silverware holder and need generous vertical clearance.
3. SPT SD-9254WA 18″ Wide Built-In Dishwasher w/Heated Drying — White
A slim body that somehow swallows 11-inch pots — the value pick for a three-person home
Here is the number that decides it for most kitchens: 17.6 inches of width. That is the Midea’s W measurement, so it slots into narrow under-counter openings most compact machines only just squeeze into. It still packs a serious interior for a unit this slim — the design clears larger plates, pots, and pans up to 11 inches in height, so a stockpot or a heavy skillet has somewhere to go. The tub is stainless steel, the panel is a digital LED display, and the adjustable legs let you level it against an uneven floor.
Where this earns its place is the feature list. You get 6 programs — Heavy, Normal, ECO, Delicate, Quick, and Rinse — plus 3 functions: Heated Dry, Hi-Temp, and Sanitize. The HYGIENE cycle holds water temperature up to 136°F (58°C) max, which is hot enough to tackle the heaviest soiled dishes and gives you a dedicated setting for baby bottles and children’s dinner sets. That is a genuinely useful combination for a family, and the quality is what owners single out most — well over a hundred people name it as the leading strength, with capacity the runner-up. Many describe quiet operation, sparkling results, and a classy stainless-tub look.
The caveat is on the service side. Value for money draws mixed feelings, and a small number of buyers have hit water leakage or a hole in the sump pump housing causing an E4 error and a leak. One case dragged through a month of back-and-forth before a refund arrived on a unit no technician ever inspected. That is a minority story, but worth knowing if you want speedy support. Buy it for the interior space and the Hi-Temp cleaning power, and keep your receipt safe.
stainless steel tub
- 17.6″ width slips into the tightest under-counter gaps
- Interior clears pots and pans up to 11 inches tall
- 6 programs plus Heated Dry, Hi-Temp, and Sanitize
- HYGIENE cycle holds water at up to 136°F (58°C)
basic features
- Value for money draws mixed opinions
- A small number report leakage or an E4 error from a damaged sump pump housing
- Service experience can be slow for some buyers
durability: a three-person household that wants big-load interior space in a narrow footprint.
advanced settings: you need the fastest possible warranty response and cannot tolerate a service wait.
4. SPT SD-9254SSA 18″ Wide Built-In Stainless Steel Dishwasher w/Heated Drying
Renter-friendly stainless with the extras that make a compact feel like a full-size machine
For anyone renting an apartment and unwilling to give up clean dishes, this SPT brings a useful set of conveniences. The time delay lets you program a start anywhere from 1 to 24 hours ahead, so you can run it off-peak or while you are out. An error alarm displays fault codes instead of leaving you guessing, and a rinse aid warning indicator tells you when to top up. The tub is stainless steel and the machine holds 8 place settings. It carries a 3-foot cable and, like its stablemate, draws 234 kilowatt hours per year.
Cleaning is the strong suit. It is what buyers praise most, with quality level alongside it, and the consistent picture is sparkle — dishes come out gleaming and the machine heats its own water to sanitize rather than relying on your tap temperature. Installation is also praised as straightforward, which counts for a lot in a job most people dread. One buyer summed it up bluntly: “Better than any dishwasher I have ever used and I have used MANY! Great power wash is very easy to install and leaves my dishes spotless!!!” That is the kind of review that sells a compact on capability, not size.
Here is the catch to weigh honestly. Drying performance is the most contested point, with several buyers reporting dishes that stay wet even on the heated dry and sanitize settings. Durability also gets a negative note — a door latch flagged as a weak spot over a 6-year run, and one unit that started leaking and showing error 4 after a few weeks. Neither is universal, but both are real. If you can live with towel-drying the odd stubborn item, the cleaning itself rarely disappoints.
stainless finish: the manual warns against feeding it pre-heated water — it heats internally, and hot supply water can push it too far.
modern look: a renter who wants stainless looks, sanitizing heat, and spotless results.
versatile cycles: bone-dry dishes straight from the cycle are non-negotiable for you.
5. Honeywell 18-Inch Dishwasher with 8 Place Settings and 6 Washing Programs — Stainless Finish
The stainless-finish compact built to sit alongside a matching appliance suite without looking the odd one out
If the rest of your kitchen is stainless, this is the compact that blends in. The finish is stainless steel, the handle is a bar type, and both the rack and basket materials are stainless steel rather than plastic — a combination that tends to age better in a hard-water kitchen. It holds 8 place settings across 2 racks with a removable cutlery basket, and the 6 wash programs cover heavy, normal, eco, glass, rapid, and rinse. A 24-hour delay start lets you schedule the run, and it is UL and Energy Star certified.
Owners describe it as a solid, well-priced 18 inch machine that fits small kitchens and holds a decent load. It installs quickly — even a novice manages with Honeywell’s YouTube walkthroughs — and it stays reliable over six months of steady use. The sanitize cycle comes in handy for baby parts, and the machine runs quiet enough to use in the background. It does not shift stubborn, multi-day baked-on residue, so a soak for the worst offenders is the realistic expectation.
Two things to plan for. The push-button controls are easy to bump, and recovering from an accidental press means a start-then-cancel reset — a small daily irritation. More seriously, a few owners mention touch buttons going unresponsive over time, leaving the unit nonfunctional despite still looking the part, and one unit arrived with an internal water valve installed backwards from the factory and needed disassembly to reverse. Overall this remains a good compact for small kitchens — just be prepared to treat the control panel gently.
tight spaces: a stainless appliance suite where looks and a quick install both matter.
premium feel: you want forgiving physical controls that shrug off an accidental bump.
6. EdgeStar BIDW1802WH 18 Inch Wide 8 Place Setting Built-In Dishwasher
A leak sensor at 52 decibels, sized to replace a trash compactor without tearing out the cabinet
At only 17.75 inches wide, this is the closest thing on the list to the narrow 17 inch slot you may have searched for, and EdgeStar points out the obvious use case: it drops in where an older appliance like a trash compactor used to sit. It holds up to 8 place settings with a silverware basket and cup tray, runs six wash cycles — Heavy, Normal, ECO, Glass, Rapid, and Rinse — and adds three options in Sanitize, Hi Temp, and Heated Dry. Quiet 52dB operation means you can run it in a small condo without shouting over the wash.
The sense of security here is the leak detection. A leakage sensor automatically shuts off the water flow when a leak is detected, which protects your floors and your downstairs neighbor’s ceiling — the kind of protection that matters most in a condo. What it is really known for is cleaning, with functionality close behind in buyer sentiment, and the pattern says it washes like a much larger machine. A compact two-person household finds it perfect, and a 1950s home with a tight galley kitchen gets a quiet unit with a roughly two-hour regular cycle that rarely needs a re-wash.
There are two sticking points. Installation is the most divided topic — some find it super easy, others call it a faff, with water plumbed out front and an unusual internal layout. Durability also draws a negative note, because a recurring E4 overflow error can take 24 hours or more to clear and may need a breaker reset you cannot easily reach. The heat dry is on the weaker side too, with dishes often still wet. It is a strong, well-protected compact if you have a patient plumber or DIY patience.
white exterior
- A leakage sensor shuts off water flow the moment it detects a leak
- 17.75″ width fits spaces a 24″ unit never could
- 52dB keeps a condo kitchen calm during the cycle
- Six cycles plus Sanitize, Hi Temp, and Heated Dry options
no heating element
- Installation splits opinion — some find it fiddly
- A recurring E4 overflow error can take a day or more to clear
- Heat dry runs weak, so some dishes come out wet
budget friendly: floor protection and a condo-friendly fit top your list.
fast drying: you need a genuinely easy install and reliable heat drying.
7. COMFEE’ 18 Inch Built-in Dishwasher with 8 Place Settings — Stainless Steel Tub
The narrow stainless model that stretches its rack up nearly two inches to fit deep pots
This one solves the compact dishwasher’s oldest problem: tall cookware. The upper rack has an adjustable height mechanism that lifts up to 1.97 inches, so deep pots clear the top even in an 18 inch body. The lower rack handles extra-large plates and oversized dishware up to 13.78 inches in height. At 52dB it runs quietly enough for an apartment, and the slim body is 17.6 inches wide, so it fits tight spaces without fuss. It measures 22.6″D x 17.6″W x 32.4″H and weighs 54.7 pounds.
The cycle options make it feel bigger than it is. Six wash cycles — Heavy, Normal, Eco, Delicate, Quick, and Rinse — are paired with Heated Dry, Hi-Temp, and Sanitize functions. Heated drying delivers a thorough, cabinet-ready dry on all cycles except Rapid and Self-Clean, so no towel drying is needed. The Hygiene wash cycle holds water temperatures up to 136°F (58°C) to handle heavily soiled dishes, and it is well suited to deep-cleaning baby bottles and children’s dinnerware. A 1-hour quick wash and a 1-24 hour delay round out the convenience.
One honest note before you order: there is no power cord in the box, so you will need to buy one separately — easy to miss and mildly annoying on install day. Otherwise the installation is smooth and the fit is precise. This is the pick for a small apartment or a compact kitchen where you want the features of a bigger machine in a slim body, including NSF sanitization and a stainless tub that feels well built.
cost savings: you want the adjustability to fit deep pots plus a sanitize cycle in a compact footprint.
quiet homes: you are ordering it — you will need to source a power cord separately.
8. Frigidaire 18 in. ADA Compact Front Control Dishwasher with Dual Spray Arms, 52 dBA
The full-code compact with a certified sanitize cycle and a delivery option that does the lifting
Buy this one when the details of installation and certification matter more than chasing the lowest outlay. It meets the appliance standards in the Americans with Disabilities Act and the Architectural Barriers Act Accessibility Guideline — that ADA compliance is a genuine requirement in some remodels, not a marketing nicety. A top and bottom rack dual spray arm system delivers a thorough wash, and the National Sanitation Foundation certified Sanitize cycle removes 99.9% of common household germs. A heating element handles heated drying, and it cleans up to 8 place settings in one cycle.
Quiet operation at 52 DBAs is a big part of the appeal — you can run it while sitting in the same room. It is 18 inches wide with dimensions of 22.5″D x 18″W x 35″H and weighs 54 pounds, and it comes with a power cord, which many compacts do not. The 6 cleaning cycles cover Energy Saver, Heavy Wash, and Rinse among others. There is a nice practical touch: room-of-choice delivery is available at checkout in select locations, so you can avoid wrestling it inside yourself. Customers note accurate dimensions and adjustable legs, and the unit fits the intended cabinet space like it was made for it — a machine for someone who has genuinely measured twice.
The honest trade-off is drying and reliability. Some owners feel the newer model’s smaller heat coil leaves dishes less dry than the unit it replaced, and there is a painful outlier — a buyer who fought a warranty battle after the machine stopped working, with repair parts never arriving. That is a rare worst case, not the norm, but with any appliance it is worth buying from a seller with a clear return path. For the right ADA kitchen, this earns its place.
ada compliant
- ADA compliant to the published accessibility standards
- NSF certified Sanitize cycle removes 99.9% of common household germs
- Dual spray arm system washes top and bottom racks
- 52 dBA keeps it quiet enough for the same room
front control
- Some find the smaller heat coil dries less effectively than older models
- An isolated warranty repair experience proved frustrating
- Costs more than the value-tier compacts
accessibility: a remodel where ADA compliance and a certified sanitize cycle are hard requirements.
top controls: you are optimising for the lowest outlay rather than code compliance.
Understanding the Specs
Decibels (dB): How Loud It Runs
Dishwasher noise is rated in decibels (dB), where lower numbers mean a quieter machine. Lower is better. A machine rated at 52dB runs about as loud as a quiet conversation, quiet enough to hold a normal spoken exchange in the same room — which several picks here, including the EdgeStar, COMFEE’, and Frigidaire, are rated to hit. If quiet matters to you, use the decibel figure on the listing as your shortcut, because it is the single easiest trait to compare straight across models.
Place Settings and Load Size
One place setting is one plate, one glass, one bowl, and one set of cutlery — the dishes for a single person. Every unit on this list is rated for 8 place settings, so each one is built to clean the dishes for up to eight people in one pass. In practice that reads generously for a one or two-person home and tighter for a larger family. The number to watch alongside it is rack adjustability, because an upper rack that can shift up clears the deep pots that otherwise force you to wash by hand.

Final Thoughts: The Verdict
Your real decision depends on three numbers: cabinet width, decibel rating, and drying performance. If you want the best all-round compact dishwasher, the Honeywell 18 Inch Dishwasher is the strongest pick, because its 18″W footprint drops into the tightest gap and its quiet running is the trait owners bring up most. If drying and interior space are your priorities, the Midea 18 Inch clears pots and pans up to 11 inches tall and holds water at up to 136°F (58°C) for a sanitize cycle. And if you need ADA compliance plus a certified sanitize cycle, the Frigidaire 18 in. ADA Compact is the one to reach for. Measure your opening first, then let fit and quiet decide the rest.
