7 Best 18 Inch Dishwashers for Apartments (October 2026) Top Picks

The best 18 inch dishwashers for apartments are the models that physically fit an 18-inch opening or roll on castors to your sink, and that stay under about 44 dB so a two-hour cycle does not run through your living space. We compared seven units that carry enough owner feedback to rank honestly: five built-ins and two rolling portables, from the most-reviewed name in the class to the newest entry.

Most apartment kitchens have a fixed set of limits that decide the purchase before any feature list matters. There is a set opening under the counter, roughly 18 inches of clearance beneath the wall cabinets, a faucet that may or may not accept a hose adapter, and a landlord who may not want a new line drilled into the wall.

Everything below is manufacturer-published specification, and where a figure is not published we say so rather than guess. Ratings and review counts are copied exactly as shown on the product page, and every noise number in this article is a manufacturer claim that has not been independently measured in a real apartment.

Top 3 Picks: Best 18 Inch Dishwashers For Apartments (October 2026)

Our short answer for most apartments is the EdgeStar BIDW1802SS. It is the widest-reviewed 18-inch built-in in this group, it drops into a standard 18-inch cutout where a trash compactor used to sit, and it is the only unit here that pairs a genuine eight-setting cavity with a heated dry option and a published leak sensor.

Quick Overview: Every 18 Inch Dishwasher We Ranked

Two of these seven roll on wheels and hook to a faucet. The other five are built-in bodies with a cutout width between 17.6 and 18 inches. Capacity is 8 place settings across the board, which means a household of four is running more than one cycle a night.

This is the unit I would put in a rental first, and the reason is the review volume rather than any single spec. At 845 owner ratings it has roughly half again the feedback of anything else in the 18-inch built-in class, which means the complaints below are pattern rather than anecdote.

The body is 17.75 inches wide against a listed cutout of 17.75 inches wide by 23 inches deep, so the fit is unusually tight but also unusually well defined. Owners note it will replace a trash compactor in the same opening, which is the single most common 18-inch retrofit in older apartment buildings.

Six cycles cover the range: Heavy, Normal, ECO, Glass, Rapid and Rinse, with Sanitize, Hi Temp and Heated Dry as options on top. The stainless steel tub is a real advantage in a compact cavity, since it holds heat for drying better than plastic-lined competitors at the same width.

Two things temper that. Installation is the part owners complain about most, because the water line exits the front of the unit rather than the back, so cabinet clearance and routing take real care. And a share of owners report an E4 overflow code that takes more than a day to clear, which in a rental is a genuine problem.

Where the EdgeStar fits an apartment best

It suits the kitchen with a trash compactor opening and a tenant who is willing to have a plumber connect it once. Drying is the quiet strength here: Heated Dry is rarely offered in an 18-inch body, and owners say the difference shows on glasses and bowls.

Where it does not fit

It is a poor match for a renter who wants something removable at move-out, since it is a fixed installation with a leak sensor and a front-exit water line. The drying agent also runs low more often than the reservoir design implies, which is a small recurring cost.

Owners also flag that fault codes appear as bare numbers on the display with no accessible breaker inside the cabinet, so a power fault means finding the breaker in the panel rather than resetting something at the unit.

At 35.63 inches tall this is a tall, narrow box on castors, and that height is the reason it works in a galley kitchen where a 24-inch portable will not. It takes up 17.64 inches of width and nothing else, which means you can park it against a side wall between cooking sessions.

The faucet adapter is in the box, so hookup takes about a minute and needs no plumber. Water use is listed at 5 gallons per cycle and energy at 237 kWh per year, and the tub is stainless steel.

Cleaning results are strong when paired with liquid detergent, and owners consistently report spotless glassware. One long-term owner describes still using it heavily after six years, which is the kind of durability signal that thin-review products on this SERP simply cannot show.

The design has quirks. The control buttons sit on the top of the loading door, so you reach over the racks, and the LED time display is hard to read with the door closed. Rack spacing is tight for large bakeware, and plastics stay damp because drying is residual heat only.

Where the SPT portable works best

It is the right answer for a one-bedroom or a shared apartment where nobody wants to sign off on a permanent installation. Rolling it to the sink and back out of the way is the whole point, and at 118 pounds the castors carry it without a fight.

Where it is awkward

It is 35.63 inches tall, so check that ceiling clearance before you order, and the drain hose does not retract into the chassis, which means it holds water after every cycle until you coil it. The sheet metal exterior is thin enough that owners describe it as delicate during moves.

This is the one where the published noise rating and the reported experience diverge, and you should know that before you decide. The spec sheet lists 52 dB, yet owners repeatedly describe it as nearly silent except for a brief pump noise.

Both facts can be true. A manufacturer rating is measured in undisclosed conditions, often on a soft surface in a lab, and a unit bolted into a cabinet with a closed door behaves very differently from one standing on hardwood. Treat the number as a class label and the owner reports as your real-world reference.

On paper the feature set is the strongest in the group for heavy soil. Six programs including Heavy and ECO, plus Heated Dry, Hi-Temp and Sanitize, and the Hi-Temp cycle holds water at up to 136F for bottles and baked-on food. It handles plates, pots and pans up to 11 inches high.

Cleaning is where owners are most enthusiastic, with specific praise for large pots and bakeware. The slim 17.6 inch body and adjustable legs make it the easiest of the built-ins to level into an uneven opening, and most DIY installers report no trouble at all.

Where the Midea suits an apartment

It is a strong fit for a tight opening where you want the quietest lived experience rather than the lowest published figure. The 54.6 pound weight is also the lightest of the built-ins here, which matters when a delivery has to cross a narrow hallway.

Where the risk sits

The risk is not cleaning, it is the service channel. Owners describe repair claims as disorganized and slow, one unit arrived with a hole in the sump pump housing, and some threw an E4 code straight out of the box. In a rental, a slow parts path is a real cost.

Most 18-inch portable units dry with residual heat alone, which is why plastics come out damp. This one has a heating element that runs during the dry cycle, and at 18 inches wide that is the feature that separates it from almost everything else on this list.

The secondary draw is the 24-hour delay start. In an apartment that matters more than it does in a house, because you can program a cycle for 9pm after the last person washes up and be asleep before the water is moving.

Maintenance cues are unusually good. There is an error alarm that displays fault codes rather than bare numerals, plus a rinse aid warning indicator and automatic detergent and rinse agent dispensers, so you are not opening the door to guess why a cycle underperformed.

Energy use is listed at 234 kWh per year with Energy Star certification, and the 17.6 by 22.6 by 32.4 inch body is identical in footprint to the Midea, which means one cabinet measurement covers both.

Where the SPT built-in works best

Choose it when drying is your top frustration or you want to run cycles overnight without planning around them. The delay start and fault-code display make it the most self-sufficient 18-inch body for a tenant who is not in the kitchen all day.

Where it is not the pick

The racks and cutlery basket are plastic and nylon rather than steel, and in a cavity holding only 8 place settings the rack spacing gets tight for large pans and sheet trays. The warranty is 1 year limited, so keep the receipt and the packaging.

At 45 dB this is the quietest portable on the list, which is the entire reason to consider it in a studio where the kitchen is the living room. Everything else about it is competent rather than exceptional.

The Quick Connect faucet assembly needs no permanent plumbing, and the 59 inch hose length is long enough to reach a sink from a fair distance. An adjustable upper rack takes taller dishes, and the tub is stainless steel.

BLACK+DECKER 18-Inch Portable Dishwasher, Energy Star, BPD8B, Black customer photo 1

Cleaning earns praise on glasses specifically, provided you run a full-length cycle rather than the short one. Six programs cover Normal, Heavy, Rapid, Glass, Eco and a 90-minute option.

The complaints concentrate in one place. Reviewers repeatedly report the drain and inlet hose connections loosening during a cycle and dripping onto the floor, and most attribute it to connections that need tightening rather than a failed machine. That is a five-minute fix, but in a rental it is water on someone else’s floor if you miss it.

BLACK+DECKER 18-Inch Portable Dishwasher, Energy Star, BPD8B, Black customer photo 2

Where the BLACK+DECKER portable works best

It suits a dorm, an RV or a first apartment where you want the lowest noise figure without a built-in, and where the 90-minute program is long enough to handle a real dinner. One owner running a BPD8B described the heated dry as doing something, which is generous for this class.

Where to look twice

The included plastic faucet adapter is thin enough to crack during installation, and the same owner noted it did not fit their tap without a hardware store trip. Check your faucet’s aerator first. Detergent needs liquid or a pod that dissolves fully, because powder does not always clear in this tub.

This is the accessibility pick, and the front control panel is the part that matters. Buttons and display sit on the top edge of the door rather than at the bottom of the tub, so the unit can be loaded without kneeling, and the whole body is listed as ADA compliant.

It is also the widest of the built-ins here at exactly 18 inches, so it needs a full 18-inch opening rather than the 17.6 or 17.75 inch cutouts the other built-ins accept. That is a real constraint in older kitchens with a narrow gap.

Frigidaire 18 in. ADA Compact Front Control Dishwasher in Black with Dual Spray Arms, 52 dBA, includes room-of-choice delivery customer photo 1

Cleaning performance is solid on everyday loads and even on heavily soiled items, helped by dual spray arms that cover both the top and bottom racks. Water use is listed at 4.9 gallons per cycle, the lowest figure published in this group, across six cycle options including Energy Saver and Heavy Wash.

The NSF certified sanitize cycle is a genuine step up for anyone washing baby bottles or immune-compromised dishware, and the heated drying system is better than residual-only drying on plastics.

Where the Frigidaire works best

It is the right choice for an accessible kitchen, a condo where a building inspection is involved, or any household that wants a certified sanitize cycle in a compact body. Accurate published measurements also make cabinet fit predictable, which is rarer than it should be.

What is not in the box

Owners report the power cord may not be included, and that a 90 degree water inlet elbow sometimes has to be bought separately. A new install also needs a hot water supply, a sink tailpiece swap and possibly an air gap, so budget for a plumber rather than assuming a weekend job.

At 42 dB this carries the lowest published noise rating of any unit we ranked, including the built-ins that cost several times more. If noise is your primary filter, the number on this spec sheet is the best in the group.

Six programs include a dedicated pots and pans cycle, plus normal, china, quick, rinse only and energy saver, with a 24-hour delay start. Three racks cover the load, with a top cutlery rack and a large removable basket.

Owners note the interior looks and performs like far more expensive 18-inch models, and several report that it dries effectively even with generic detergent. It is UL listed, ADA compliant and Energy Star certified.

The body is 18 inches wide at 22.6 inches deep and 32.4 inches high, and at 70 pounds it is the heaviest built-in here, so plan the delivery path before the box arrives.

Where the Honeywell works best

It fits an existing 18-inch cabinet opening precisely and suits anyone buying on noise alone. The push-button controls have nothing that wears off, which is a small thing that matters over five years in a rental.

What to watch

The warranty is 1 year and the racks are plastic and nylon, not metal. One owner reported an E4 error with internal water pooling within a month, and others mention a small package arriving with a loose or broken part inside, so open the box before the delivery driver leaves.

How to Measure Your Apartment Kitchen Before You Order

Yes, an 18 inch dishwasher fits a small apartment kitchen, but only if three measurements line up: the width of your opening, the depth available with the door open, and the clearance under your wall cabinets. Get those numbers before you compare a single feature.

First, measure the opening width at the narrowest point, not the widest. A 17.6 inch body needs a 17.6 inch opening or larger, and building a cabinet around a tight fit leaves no room for leveling tolerance.

Second, measure depth with the door fully open. The EdgeStar publishes 42.25 inches of depth with the door open against a 22.4 inch body, which tells you exactly how far the door swings into your walkway. In a galley kitchen that swing is the difference between usable and not.

Third, check clearance beneath the wall cabinets. Portable units stand 35.63 inches tall, so a standard upper cabinet will not clear them, which usually means rolling the unit to the sink and back rather than parking it permanently.

While you have the tape out, look at the faucet. A removable threaded aerator is the real gating requirement for a portable hookup, and if the aerator is fixed you are looking at a faucet swap before the dishwasher works at all.

If your kitchen has no floor space to spare at all, a countertop unit is the remaining option. We cover those in our countertop dishwasher picks, and our small kitchen dishwasher guide covers the 24-inch class for kitchens that do have the width.

Noise in an Apartment: What the Decibel Number Actually Means

A 52 dB dishwasher is noticeable in a studio apartment. The widely cited threshold is 44 dB, below which a cycle sits near the level of a quiet conversation, and the practical rule is that every 10 dB step reads as roughly twice as loud to the human ear.

That gap matters. On this list the spread runs from 42 dB on the Honeywell to 52 dB on the EdgeStar, SPT SD-9263W, Midea, SPT SD-9254SSA and Frigidaire, and the BLACK+DECKER sits in between at 45 dB. Eight decibels is a real, audible difference in a room with hard floors and no soft furnishings.

Two caveats before you chase the lowest number. Manufacturer ratings are measured in undisclosed conditions and are not independently audited, and a unit bolted into a cabinet with the door closed behaves differently from the same unit standing on wood. Owner reports consistently show more quiet from installed built-ins than from their spec sheets suggest.

Surface and mounting carry more weight than the label. Hard floors, tile and laminate reflect pump noise, and a portable unit with its hose draped across a hard floor adds a rattle that the rating does not capture. Isolation feet and a firm, level base do more for a studio than two decibels of specification difference.

Built-In vs Portable vs Countertop: Which One Fits an Apartment

Built-in units give you the quietest and best-drying result and no floor space at all, but they need plumbing permission and a permanent opening. Portables give you flexibility and a wheel-mounted footprint you can move, at the cost of floor space and residual-only drying on most models.

Countertop units sit on your worktop, need no floor space and can run from a hand-filled tank with no plumbing at all, which makes them the easiest option in a rental. They also hold the fewest dishes, and none of the seven units ranked here are in that class.

A practical decision rule: if you have an 18-inch opening and permission to plumb, build in. If you have floor space but no opening, go portable. If you have neither, a countertop unit is the only honest answer.

For the cooking side of a small kitchen, our induction cooktop picks for apartments cover the other appliance that tends to dictate the counter layout.

Which 18 Inch Dishwashers Are Most Reliable and Which Parts Fail

The most reliable 18-inch dishwashers on this list are the ones with the largest owner feedback and the fewest named part failures, which here points to the EdgeStar BIDW1802SS and the two SPT models. No independent service-rate data exists for this class, so we are ranking by reported failure patterns instead of pretending to a repair database we do not have.

The recurring failure across the 18-inch portable class is the hose connection. Reviewers of the BLACK+DECKER BPD8B report drain and inlet connections loosening during a cycle and dripping, and other owners running the same model describe the rear hose coupling weeping on a fair number of units. SPT SD-9263W owners report the same class of problem in a different form, with a drain hose that does not retract and holds water after every run.

The second failure is the E4 overflow code. It shows up on the EdgeStar, on the Midea out of the box, and on the Honeywell within a month for one owner. On the EdgeStar the code appears as a bare numeral with no user-accessible breaker, so clearing it can take more than 24 hours, which in a rental is a real problem.

The third is the drain pump. One BLACK+DECKER owner reported a pump failure at 17 months with no service response, and the Midea has at least one report of a sump pump housing arriving damaged. On the Midea the deeper issue is the service channel, which owners describe as disorganized and slow rather than the machine itself.

Two mitigations are worth the effort. Tighten every hose coupling by hand before the first cycle and again after the first month, and open the box in front of the delivery driver so shipping damage is documented rather than argued. See also our apartment tabletop grill guide for the same renter-first approach to a compact appliance.

Renter’s Checklist: Hookups, Landlord Approval and Moving Out

A portable dishwasher does not need a special faucet, but it does need a removable threaded aerator. The quick-connect adapter screws onto that aerator, so a fixed or non-removable aerator means a faucet replacement or an adapter purchase before the first cycle.

Ask the landlord in writing before a built-in goes in. A new water line, a sink tailpiece swap and a hole for an air gap all cut into cabinetry or the wall, and those are the changes most likely to be refused. A portable that rolls to the sink is far easier to approve.

Plan the drain route. The simplest renter arrangement is the drain hose into the sink, which needs no wall penetration, but check your lease for any prohibition on standing water in a sink. A building connection point is tidier and usually needs permission.

For a built-in, confirm hot water supply, a sink tailpiece swap, and whether a 90 degree water inlet elbow and the power cord are included, because those are the parts most often missing from the box.

Finally, plan the removal. A portable is unplugged, drained and rolled out in about ten minutes. A built-in is a plumber’s job twice, which is why it is worth deciding at the start whether you will be in that apartment in two years.

Frequently Asked Questions

Is a 52 decibel dishwasher loud?

Yes, in a small apartment. 52 dB is well above the 44 dB quietness threshold and is clearly audible in a studio where the kitchen shares a room with the living area. In a closed kitchen behind a door, it is usually tolerable. The five 18-inch units rated at 52 dB on this list are built-ins; the BLACK+DECKER portable is listed at 45 dB and the Honeywell built-in at 42 dB.

What’s a good dB rating for a dishwasher?

44 dB or below is the commonly cited quietness threshold for dishwashers. Below that, a running cycle sits near the level of a quiet conversation rather than a washing machine. Because every 10 dB step reads as roughly twice as loud, moving from 52 dB to 45 dB is a genuine improvement in a studio or open-plan apartment.

Which 18-inch dishwasher is the most reliable?

Among the seven units ranked here, the EdgeStar BIDW1802SS has the largest owner feedback base at 845 ratings and the fewest recurring hardware complaints, with the SPT models close behind. No independent service-rate data exists for the 18-inch class, so reliability is judged from reported failure patterns rather than published repair statistics.

Do portable dishwashers need a special faucet?

They need a removable threaded aerator on the kitchen faucet, which is what the quick-connect adapter screws onto. Most standard kitchen taps have one, but a fixed or non-removable aerator means a faucet swap or a different adapter. A hardware store trip before ordering is a good way to avoid a dead dishwasher on delivery day.

Can an 18 inch dishwasher fit in a small kitchen or apartment?

Usually, if you measure first. Check the opening width, the depth needed with the door fully open, and the clearance under your wall cabinets. Built-ins on this list need between 17.6 and 18 inches of width, and portable units stand 35.63 inches tall, so they roll to the sink rather than parking under a standard cabinet.

Are 18 inch dishwashers ADA compliant?

Some are. The Frigidaire FFBD1831UB is listed as ADA compliant with front panel controls for loading without kneeling, and it carries an NSF certified sanitize cycle. The Honeywell HDS18W is also listed as ADA compliant under-counter. Confirm the specific model’s compliance before ordering, since not every 18-inch model claims it.

The Best 18 Inch Dishwasher for Your Apartment

The EdgeStar BIDW1802SS is our pick for most apartments in 2026, because it has the widest owner feedback base in the 18-inch class and a 17.75 inch cutout that replaces a trash compactor in older buildings. If you cannot drill into the cabinetry, the SPT SD-9263W is the pick that rolls to the sink on castors and needs no permission.

Judge the whole list on two numbers: the width of your opening and the noise you can live with at 10pm. Every unit here holds 8 place settings, so a household of four runs more than one cycle a night, and none of them dries plastics as well as the SPT SD-9254SSA with its heated element.

Measure the kitchen, check the aerator, and only then order. Those ten minutes decide more about whether the dishwasher works in your apartment than any specification on the page.
