A dishwasher in a small apartment is a completely different purchase problem than a dishwasher in a house. There is no dedicated water line, no drain hookup, no empty cabinet bay waiting for a 24-inch body, and often a lease that says no. What you actually need to solve first is not cleaning power — it is footprint and permission.
The good news is that a whole category now exists for exactly this situation. Our team pulled the specs on every countertop, portable and slim built-in unit that fits a studio or one-bedroom kitchen, cross-checked the review data on each, and narrowed it to eight that are genuinely worth your counter space. If you want the broader picture of full-size machines first, read our guide to the best dishwashers overall before you come back here.
Here is the direct answer: a good small apartment-sized dishwasher is a countertop unit holding 4 to 6 place settings with a built-in 5L water tank, because the tank means no faucet work, no plumbing and no landlord conversation. Three formats compete for the same shelf, and the deciding factors are counter depth, how many dishes you generate in a day, and whether wet dishes are acceptable to you.
Each machine in this roundup runs real wash cycles like its full-size cousin — heated water, rotating spray arms, detergent, a dry cycle — just with fewer place settings and a smaller tub. Our advice for anyone in a tight space applies broadly, whether you are also shopping for compact cooking appliances or space-saving fitness gear that has to live in the same square footage.

Measure Your Kitchen Before You Buy
Measure four things before you order anything, because the majority of return stories in this category start with a unit that physically would not fit or could not reach the drain. Ten minutes with a tape measure saves a return trip.
1. Counter depth and width. Most apartment counters are 24 to 25 inches deep, which sounds generous until you account for the backsplash and the wall socket. The seven countertop machines here range from 16.53 inches wide to 21.7 inches wide and from 16.73 to 21.5 inches deep. Measure the flat run, not the total counter.
2. Under-cabinet clearance. Several of these machines are 18 inches or taller, and a standard upper cabinet with a 17-inch clearance will block them completely. If your vertical space is under 18 inches, your realistic options narrow to the 17.2-inch-tall units or to a rolling cart.
3. Faucet-to-drain distance. If you plan to run the machine in faucet mode, the drain hose has to reach over the sink rim into the basin, and the inlet hose has to reach the faucet. The supplied hoses range from 59 to 61 inches on most of these models, which is generous, but the routing has to physically work around your faucet base.
4. Outlet reach. Cord lengths are around 55 to 60 inches. In many galley kitchens the nearest outlet is on a different wall, and extension cords are a fire risk with any appliance that draws heating power.
1. Hermitlux Countertop Dishwasher – Our Best Overall Pick
Hermitlux Countertop Dishwasher, 7 Washing Programs Portable Dishwasher
5 place settings
5L built-in tank
16.73D x 16.85W x 18.23H inches
50 dB, 30.9 lb
Pros
- Deepest review history in the roundup at 4583 ratings
- 7 wash programs including Glass and Self-clean
- Built-in 5L tank means the sink stays free during cycles
- 18-hour delay start for off-peak rates
- Glass door with LED interior light
Cons
- Only 5 place settings so large households need multiple loads
- Taller than most rivals at 18.23 inches so plan cabinet clearance
- Some residual water is normal after factory testing
This is the machine we kept coming back to while comparing the group, and the reason is unglamorous: it has the largest body of real owner feedback of any countertop machine in this roundup, at 4.4 stars across more than 4,500 ratings. When a category is this new and this fragmented, review volume tells you more about long-term reliability than any spec sheet.
The footprint is 16.73 inches deep by 16.85 inches wide by 18.23 inches tall, which means it clears a standard counter but will not slide under a low cabinet. At 30.9 pounds it is light enough to lift onto a rolling cart or a shelf when you need the counter back.
Cleaning-wise it runs 7 programs — Standard, Quick, Strong, ECO, Fruit, Self-clean and Glass — plus Delay, Child Lock and Dry functions, driven by 14 jets across top and bottom spray arms. Plates up to 10.25 inches fit when loaded at an angle, and the 5L tank consumes about a fifth of the water a typical handwashing session uses.
For drying, you get 60 minutes of hot air followed by 72 hours of automatic ventilation, which is what stops the musty smell that plagues smaller machines. The 18-hour delay start is genuinely useful in an apartment where you want the cycle finished before you get home rather than running overnight.
Why it works for one and two-person households
Five place settings is the sweet spot for a couple or a solo renter. It covers a full day of breakfast and dinner dishes without you scraping and re-loading twice, which is the failure mode that makes people abandon small dishwashers entirely.
The tank mode is the real unlock. Because water sits in an internal reservoir rather than flowing from your tap, you can wash your hands, fill a glass and rinse a pan while a cycle runs. Reviewers consistently describe that single feature as the reason they stopped hand-washing everything.
Where it falls short
The 18.23-inch height is the constraint to plan around. In a kitchen with 17-inch cabinet clearance you will need a rolling cart, which then occupies floor space and still needs a nearby outlet.
Capacity is genuinely 5 place settings, so a family of four will run it twice a day. And like most plastic-tub units, expect a small amount of standing water after factory testing — run one empty cycle before your first real load. The warranty is one year manufacturer, which is standard across this category.
2. COMFEE 6-Place Countertop Dishwasher – Best for Full Loads
COMFEE’ Countertop Dishwasher, Energy Star Portable Dishwasher, 6 Place Settings & 8 Washing Programs, Speed, Baby-Care, ECO& Glass, Dish Washer for Dorm, RV& Apartment, Black
6 place settings
Stainless steel tub
19.7D x 21.7W x 17.2H inches
52 dB, 46 lb
Pros
- Largest interior among the countertop machines here at 6 place settings
- Eight wash cycles including a 45-minute Speed cycle
- Stainless steel interior and 360-degree spray for solid cleaning
- Energy Star certified using as little as 2.77 gallons per cycle
- Backlit LED display shows remaining cycle time
Cons
- At 46 pounds it is one of the heavier units to lift
- Supplied faucet adapter does not fit many pull-down faucet models
- Drying is weak unless you enable the dry function and crack the door
- Some owners report hose and connection leaks after a few months
If your apartment generates more dishes than a 5-place-setting machine swallows, this is the one to look at. At 19.7 inches deep, 21.7 inches wide and 17.2 inches tall, it is the biggest countertop machine here — but at 17.2 inches tall it is also one of the few that actually clears a low cabinet.
It shares the stainless steel interior tub found on the BLACK+DECKER, but it carries that tub on a larger 6-place-setting rack, which matters for heat retention during the cycle and rust resistance over years. The Heavy program uses 12 nozzles with 360-degree spray and water up to 154 F, and the Speed program finishes a load in 45 minutes when you need dishes back fast.
Buyers in apartments and older homes without a dishwasher hookup consistently rate it as transformative, frequently comparing it to full-size machines they previously owned. It can sit on the counter or tuck into a cupboard for a built-in look, and it is Energy Star certified at as little as 2.77 gallons per cycle.
Two cautions come up repeatedly in the reviews. The first is faucet compatibility — the supplied adapter does not fit many pull-down faucet styles, so check your faucet before ordering. The second is drying: without the extra-dry function and the door left cracked, dishes come out damp.
Why it works for couples and small families
Six place settings means a full day’s dishes from three people fit in one load, and the stainless tub holds heat well enough that the wash stays effective on a longer cycle. The 45-minute Speed cycle is the real time-saver on a weeknight when you want the machine done before bed.
At 17.2 inches tall it is one of the two shortest machines in the roundup, and a strong choice if your under-cabinet space is tight, which is common in older apartment buildings where the upper cabinets hang low.
Where it falls short
Weight is the first issue. At 46 pounds this is a two-person lift, and moving it in and out of a cabinet is the kind of task that ends with a dropped machine or a strained back.
The 21.7-inch width and 19.7-inch depth mean it needs a genuinely clear stretch of counter. Plates larger than standard size must be angled, which wastes rack space, and there is a documented stream of reports about connection leaks developing after a few months of use — check hose fittings periodically.
3. NOVETE 4-Place Countertop Dishwasher – Top Rated
NOVETE Portable Countertop Dishwashers for Small Apartments
4 place settings
5L tank with level indicator
16.8D x 16.9W x 18.1H inches
50 dB, 28 lb
Pros
- Accepts dishes up to 12 inches loaded at an angle
- Baby Care/Heavy mode reaches 167 F for bottles and canning jars
- Lightest weight here at 28 pounds so easy to reposition or cart
- Built-in 5L tank plus faucet mode means no installation
- 29-minute speed mode
- Includes a fruit basket and full accessory set
Cons
- Smallest capacity here at 4 place settings
- Drying is partial with cups retaining water at the top
- Dry mode ventilation fan emits a high-pitched whir
- Residual water inside after delivery needs one empty first run
The NOVETE is among the most widely reviewed machines in the roundup with more than 2,500 ratings and also accepts unusually large plates, which solves a specific problem the others do not. It fits dishes up to 12 inches when loaded at an angle, which covers square dinner plates and shallow serving bowls that refuse to fit in most mini machines.
The body is 16.8 by 16.9 by 18.1 inches, and at 28 pounds it is the easiest machine in the group to move — onto a rolling cart, onto a shelf, or back under the cabinets when you need the space.
The double-layer rack fits 4 serving bowls, 4 cups, 4 small plates, 4 dinner plates and 21 pieces of cutlery, which is a well-designed layout for a small footprint. Five cycles include Economy, Intensive, Normal, Rapid and Rinse, with a Baby Care/Heavy mode that reaches 167 F — hot enough to sanitize baby bottles and home-canning jars.
It also runs a 3-in-1 function combining dishwasher, dryer and storage cabinet, with 60-minute hot air drying followed by 72 hours of automatic ventilation to prevent moisture and odors. A transparent dual-layer glass door with an LED lamp lets you watch the cycle rather than guessing.
Why it works for solo residents and couples
Four place settings is the smallest rack in the roundup, but the double-layer layout makes it work hard — it is a full day of dishes for one person and comfortably a day for two. The 29-minute speed mode means a lightly soiled evening load is finished before a film finishes.
Light weight is the underrated advantage here. In a rental, being able to move the machine without help is the difference between owning a dishwasher and renting the counter space it occupies.
Where it falls short
Capacity is the smallest in the group. A household of three will run two loads a day, and the angle-loading requirement for large plates eats rack space quickly.
Drying is partial rather than complete — cups and glasses retain standing water at the top, and the ventilation fan in dry mode emits a high-pitched whir that some owners find noticeable in a quiet apartment. Expect residual water inside after delivery from factory testing; run one empty cycle first.
4. BLACK+DECKER BCD6W – Best Recognizable Brand
BLACK+DECKER Countertop Dishwasher, Energy Star Certified, BCD6W, White
6 place settings
Stainless steel interior
21.5D x 21.7W x 17.2H inches
60 dB, 46.2 lb
Pros
- Recognizable brand with a main appliance division behind it
- Seven wash cycles including Eco and 90-minute programs
- Stainless steel interior that wipes clean easily
- Stores neatly in a cupboard or pantry when not in use
- Energy Star certified
- Quick-connect faucet hookup with no permanent plumbing
Cons
- One of the largest countertop machines at nearly 22 inches wide
- Supplied 59-inch inlet hose is often too short from inside a cabinet
- Plates over 10.5 inches must be washed separately or angled
- Weak drying without rinse aid
- Some owners report internal leak or error codes after a few months
When you are renting and something breaks, brand name matters more than it does in a house you own. Parts are easier to source, service is easier to find, and a recognized main appliance division behind the product is a meaningful difference from an unbranded white-label machine.
The BCD6W holds 6 place settings including plates, bowls, mugs, wine glasses and utensils, across seven cycles: Normal, Intensive, Eco, Glass, 90 Minutes, Rapid and Soak. It has a 24-hour delayed start and a child lock, both of which matter if you share a small kitchen with a toddler.
Long-term owners frequently post multi-year updates confirming the machine keeps working when filters and hoses are maintained monthly, which is the strongest durability signal we found among machines with a stainless tub. The stainless steel interior and racks are easy to wipe down and resist the staining that shows up on plastic tubs.
It measures 21.5 by 21.7 by 17.2 inches and stores in cupboards, pantries or on shelves when not in use, which partly offsets the large footprint. The Quick Connect assembly hooks straight to the faucet with no permanent plumbing.
Why it works for renters who want support
This is the pick if your lease or your location means a service visit could be expensive or slow. A main appliance brand behind the machine is the difference between a warranty claim that gets honored and one that does not.
The six-place-setting capacity and stainless tub also put it on par with the COMFEE for actual cleaning durability, while the 90-minute program is a good middle ground between a full cycle and the 45-minute speed runs.
Where it falls short
It is one of the largest countertop machines here — nearly 22 inches wide and 21.5 inches deep — so it demands a real stretch of clear counter. At 46.2 pounds it is also among the heaviest.
Two practical complaints recur: the supplied 59-inch inlet hose is often too short to reach from inside a cabinet, and plates larger than about 10.5 inches must be washed separately or angled in. Drying is weak without rinse aid. There is also a documented stream of internal leak and error code reports after a few months, so inspect fittings regularly.
5. EUHOMY Countertop Dishwasher – Budget Pick at 40 dB
EUHOMY Countertop Dishwasher Portable, 6 Programs with 40 dB, No Hookup
30+ items / 5L tank
40 dB operation
16.85D x 16.73W x 18.03H inches
28.6 lb
Pros
- Quietest machine in the group at 40 dB for open-plan and work-from-home setups
- Highest rating here at 4.5 stars across more than 1000 reviews
- Tank-first design lets you use the sink freely during a cycle
- ETL and DOE certified
- Light at 28.6 pounds and easy to move between locations
Cons
- Tall enough that several owners needed a rolling cart
- Drying is the most criticized feature without extra 60-minute dry cycles
- Poorly spaced rack pegs and a weak cutlery holder require careful loading
- Faucet adapter is not included and must be bought separately
- No dedicated detergent compartment so powder settles on the tub floor
If your apartment is studio-style, open-plan, or you work from home and cannot tolerate background noise, this is the machine to buy. At 40 dB it is 10 dB below the next quietest machines in this roundup, which is a difference you hear clearly when a cycle runs for an hour in a small room.
For scale, normal conversation sits around 60 dB and a typical television in a living room runs 50 to 55 dB. At 40 dB this machine runs underneath an ordinary conversation rather than over it.
Capacity is 5 liters and 30+ items including plates up to 10.25 inches, and the body measures 16.85 by 16.73 by 18.03 inches at 28.6 pounds. Six programs cover Normal, Quick, ECO, Baby Care/Heavy, Fruit and Dry, with dual spray arms for 360-degree coverage and a Baby Care mode reaching 167 F.
Owners describe cleaning power as matching a full-size dishwasher, which is a strong claim repeated often enough to be worth testing yourself. The 29-minute quick cycle handles lightly soiled evening loads, and the ETL and DOE certification means it has passed independent safety and efficiency testing.
Why it works for noise-sensitive homes
The 40 dB figure changes what you can do while it runs. You can hold a video call, cook, or have a conversation in the same room without raising your voice — which is not true of the 60 dB and 62 dB machines at the other end of this list.
The tank-first design compounds the benefit: you are not tethered to the faucet, so the machine can sit on a rolling cart in the corner of the kitchen rather than pressed against the sink.
Where it falls short
At 18.03 inches tall it does not fit under many cabinets, and several owners had to buy a rolling cart to solve that. Drying is the most criticized feature — items come out wet unless you add extra 60-minute dry cycles.
Loading requires care: rack pegs are poorly spaced and the cutlery holder is weak, so small items can fall through. Dishes need rinsing first or food residue remains, and there is no dedicated detergent compartment, so powder falls to the bottom of the tub. The faucet adapter is not included — budget for it if you want faucet mode.
6. HAVA Countertop Dishwasher – Best for Large Plates
HAVA Countertop Dishwasher, 6 Programs Portable Dishwasher with Water Tank
4 place settings / 30+ pieces
5L built-in tank
16.8D x 16.7W x 18H inches
60 dB, 28.7 lb
Pros
- Handles dishes up to 11 inches loaded at an angle
- Heavy/Baby Care mode at 167 F doubles as a sanitizer for canning jars
- Light at about 28.7 pounds and easy to reposition between locations
- No-hookup tank lets you place the machine anywhere and keep using the sink
- Garden-hose thread connector is standard so plumbing parts are easy to source
Cons
- Drying is weak with cups and glasses retaining standing water
- Drying fan makes a high-pitched whistling sound
- Filter lets small food particles into the spray arms which then need cleaning
- Suction cup on the drain hose does not hold reliably on a sink wall
- Will not fit under standard cabinets in many kitchens
The HAVA is the pick if your dishes are the problem rather than your space. It fits plates up to 11 inches loaded at an angle and is regularly reported to handle heavy items like a slow-cooker crock, which no other 4-place-setting machine here manages comfortably.
Its 5L built-in water tank means no installation at all, and the garden-hose thread waterline connector is a standard fitting — which matters more than it sounds, because replacement connectors and adapters are then easy to source at any hardware store rather than special-ordered.
Six programs cover Normal, Speed, Soft, Heavy/Baby Care, Fruit and Dry, with 14 water ports across the spray arms giving 360-degree top and bottom coverage. Water use is 5 liters per cycle, and the machine adds 60 minutes of hot air drying plus 72 hours of automatic ventilation. A fruit basket is included.
Buyers consistently praise the tank-first approach, and several note that the first-run plastic smell fades after about ten cycles — worth knowing so you do not return it prematurely.
Why it works for one person with big dishes
A solo renter cooking with a wok, a sheet pan or a wide serving bowl will find the 11-inch plate accommodation genuinely useful. Combined with the 167 F sanitize mode, it doubles as a baby-bottle and canning-jar cleaner.
At roughly 28.7 pounds it moves easily, so you can store it on a high shelf or a rolling cart and bring it out only on the days you use it.
Where it falls short
The listed noise figure is 60 dB, the second-highest in the roundup, and the drying fan adds a high-pitched whistling sound on top of that. In a studio apartment that will be noticeable.
Drying is weak — cups and glasses retain standing water. The filter lets small food particles through into the spray arms, which then need cleaning, and the supplied suction cup on the drain hose does not hold reliably on a sink wall, so plan a clamp or an alternate drain route. At 18 inches tall it will not fit under standard cabinets in many kitchens.
7. EdgeStar BIDW1802SS 18 Inch Built-In – Best for Narrow Kitchens
EdgeStar BIDW1802SS 18 Inch Wide 8 Place Setting Built-In Dishwasher
8 place settings
17.75-inch body width
17.63D x 22.44W x 32.5H inches
52 dB, 62.8 lb
Pros
- Only true built-in in the roundup and the largest capacity at 8 place settings
- 17.75-inch width fits narrow and galley kitchens where 24-inch machines will not go
- Quiet at 52 dB despite the larger tub
- Cleaning reported as strong with no residue
- Leakage sensor adds a real safety net in a rental or older home
Cons
- Installation is significantly harder than the portable machines and an install kit may be needed
- Drain is plumbed out the front which can conflict with a standard kick plate
- Heat dry is mediocre and dishes are often still wet when the cycle ends
- Full cycles run close to two hours
- E4 overflow codes can take more than 24 hours to clear
This is the pick for a narrow kitchen with a real dishwasher bay — a galley layout, or a hole left by an old trash compactor or a removed appliance. At 17.75 inches wide it can go where a standard 24-inch machine never will, and it holds 8 place settings, more than any countertop machine in this roundup.
It is not a machine for a renter unless your lease explicitly permits built-in installation, which most do not. If you own the unit or have written permission, it is the most capable machine here by a wide margin.
Six cycles — Heavy, Normal, ECO, Glass, Rapid and Rinse — plus Sanitize, Hi Temp and Heated Dry options, running at 52 dB. The stainless steel interior, racks and basket are durable and easy to wipe, and it carries an Energy Star rating at 234 kWh per year.
Owners who measured their 18-inch opening and brought in a plumber are largely delighted: quiet, roomy for its size, and inexpensive compared with full-size built-ins. The leakage sensor automatically shuts off water flow when it detects a leak, which is meaningful in an older building.
Why it works for narrow galley kitchens
Eight place settings means a family of four finishes in one load, and the taller tub has room for items that countertop machines reject outright. At 52 dB it is quieter than most of the countertop machines here despite washing considerably more.
The 17.75-inch width is the whole point. If your kitchen has an 18-inch opening that has been useless for decades, this is the one machine in the roundup that uses it.
Where it falls short
Installation is the honest drawback. It is significantly harder than any countertop machine, a plumber and an install kit may be needed, and the drain is plumbed out the front of the machine, which can conflict with a standard kick plate.
Heat dry is mediocre — dishes are often still wet at the end — and full cycles run close to two hours. There is no accessible breaker on the unit itself, so a reset means finding your household breaker, and the drain-line fitting can throw an E4 overflow code that takes more than 24 hours to clear. Baking sheets and oversized pots still need hand-washing.
8. COMFEE 6L Tank Dishwasher – Best for Sanitizing Cycles
COMFEE’ Countertop Dishwasher, Portable Dishwasher with 6L Built-in Water Tank, Mini Dishwasher with More Space Inside, 7 Programs, UV Hygiene& Auto Door Open, for Apartments, Dorms& RVs, White
6L built-in tank
Fits 10.5-inch plates
17.13D x 16.53W x 18.3H inches
62 dB, 41.3 lb
Pros
- Auto-open door plus turbofan produces genuinely dry dishes unlike most countertop machines
- UV hygiene cycle and 192 F maximum wash are unusual at this level
- Upgraded interior fits 10.5-inch plates
- 6L tank means no faucet hookup needed at all
- Resumes automatically after a breaker trips mid-cycle
Cons
- Loudest of the countertop models at 62 dB
- Lowest rating in the roundup at 4.1 stars with 12 percent one-star reviews
- Full normal cycle runs about two hours and ten minutes
- Powder detergent is required because pods do not dissolve properly
- Capacity is closer to 2 or 3 place settings than the dimensions suggest
The distinguishing feature here is drying. The door opens automatically at the end of each cycle and a built-in turbofan vents steam, and that combination produces genuinely dry, cabinet-ready dishes — the single most common complaint about every other countertop machine in this roundup.
The second distinguishing feature is temperature. The Hygiene cycle rinses at 162 F and reaches 192 F on Max, and a UV function adds a sanitation pass on top. If you have a newborn, or you home-can in summer, this is the strongest sanitizing performance available in a countertop format.
The 6L built-in tank means manual filling with no faucet work at all, though a quick-connect hookup with an adapter is included if you prefer it. Water use is 6L per cycle, around 60 percent less than hand-washing, and 0.35 kWh per normal cycle. It includes an inlet hose with adapter, fruit basket, tableware basket, water pitcher and drain hose.
Long-term owners report years of reliable use and easy filter cleaning, and the resume-after-trip feature means a mid-cycle breaker trip does not force you to drain and refill the tank.
Why it works for households with babies
The 192 F maximum wash and UV hygiene cycle handle baby bottles and children’s dinner sets in a way that a 167 F heavy cycle on the other machines cannot match. For parents in a small apartment, that removes the need for a separate bottle sterilizer on the counter.
The auto-open door also means you load it, start it and walk away — there is no standing at the machine waiting to crack the lid for steam escape.
Where it falls short
It is the loudest countertop model here at 62 dB, and it carries the lowest rating in the roundup at 4.1 stars with 12 percent one-star reviews. The normal cycle runs about two hours and ten minutes, so it is not a same-evening appliance for most people.
Two real limitations catch people out. Powder detergent is required — pods do not dissolve at this machine’s operating temperature and will leave residue. And despite the 6L tank, actual capacity is closer to 2 or 3 place settings, so budget for two loads a day. The supplied suction cup for the drain hose is ineffective, so add a hose clamp.
Countertop vs Portable vs 18-Inch Built-In
A countertop unit sits on your counter and runs from a built-in water tank. A portable dishwasher is a rolling unit on casters that connects to a faucet and drains into the sink. An 18-inch slim built-in installs permanently into a narrow cabinet bay. For most apartments, the countertop format wins; the other two exist for specific constraints.
Choose a countertop dishwasher if you have no hookup, no landlord permission, or under 22 inches of clear counter. It requires no plumbing, stores away when not in use, and is the only format that leaves your sink free while a cycle runs. Every pick in the top three above is a countertop machine for exactly this reason.
Choose a portable dishwasher if you have no counter space at all. It lives on the floor and rolls into position, and it holds substantially more than a countertop unit — typically 6 to 8 place settings. The trade-off is that it monopolizes your faucet during a cycle, and retractable hose-style pull-down faucets will not accept a standard intake hose at all.
Choose an 18-inch slim built-in if you own the apartment and have a narrow bay. It is the most capable option by a wide margin, with 8 place settings and a full-size tub, but it needs a plumber, a permanent water line and usually landlord or owner sign-off. Check your cutout dimensions before anything else: the EdgeStar needs a 17.75-inch-wide by 23-inch-deep by 32.5-inch-tall opening.
Buying Guide for Apartment Dishwashers
Place settings: how the number translates to real people. One place setting is a dinner plate, a bowl, a set of cutlery and a glass. A 4-place-setting machine suits one person or a couple. A 6-place-setting machine covers a household of three comfortably. Above that, you are looking at a portable or an 18-inch built-in, because no countertop machine here will handle a family of four in one load.
Water source: tank, faucet adapter, or hard line. A built-in water tank means you fill it manually and the machine is fully self-contained — no faucet, no plumbing, no landlord conversation. This is the single most important feature in a rental. Faucet mode gives you unlimited water and no refilling, but requires a compatible faucet and blocks the sink during the cycle. A hard line hookup is permanent plumbing and effectively rules out renting.
Do you need a faucet adapter? If you plan to run in faucet mode, yes, and you may need to buy one separately — the EUHOMY does not include it. Know your faucet style first. Standard fixed faucets with a threaded spout generally accept an adapter. Pull-down faucets, retractable hose-style faucets and touch-activated faucets usually do not, and forcing an improvised adapter is a leading cause of mid-cycle leaks and dirty water spilling into the sink. Plumbers advising in r/Plumbing point at the faucet aerator seal as the correct fix point rather than clamping the hose harder.
Renter and lease rules. Some rental agreements prohibit portable or built-in dishwashers outright, and a few prohibit any appliance that draws water beyond the sink. A countertop machine with a tank is the safest option in a strict lease because it requires no plumbing and no permanent alteration — but read your agreement, because in a shared building an unattended appliance that leaks can become your liability. Ask your landlord in writing before installing anything that connects to the supply line.
Water and energy. These machines use 5 to 6 liters per cycle on a standard program, against the far higher volume a running faucet uses during hand-washing. Energy draw is modest: 0.35 kWh per normal cycle on the COMFEE 6L model, and roughly 950 watts peak on several others. Against a full-size dishwasher at 6 to 10 gallons per cycle, the savings are real but the absolute numbers are small — the larger saving is in your time.
Drying is the most-criticized feature in this entire category. Six of the eight machines here leave cups and glasses with standing water unless you add rinse aid, enable the extra dry function, or leave the door cracked open. Only the COMFEE 6L model resolves this properly with an auto-opening door and a turbofan. If wet dishes make you avoid the machine entirely, weight that machine higher regardless of its other strengths.
Detergent matters more than you expect in small units. Low-water machines run cooler internal temperatures than full-size machines, and the COMFEE 6L model specifically cannot dissolve pods properly — powder is required. Check the detergent guidance for whichever machine you buy, because residue from a non-dissolving pod will end up on your dishes and inside the tub.
Noise, in apartment context. The range here is 40 dB to 62 dB, which is a wide spread and a genuinely important filter for thin-walled apartments. Anything at 60 dB or above is audible over a conversation in the same room. If you work from home, weight the EUHOMY heavily.
Should You Buy a Dishwasher at All?
For one or two people in a very small kitchen, hand-washing can genuinely be the better call, and we would rather say so than sell you a machine you resent. A typical faucet runs 1.5 to 2 gallons per minute, so ten minutes of filling a basin, scrubbing and rinsing can use more water than five cycles of a countertop machine combined. The counter space a machine permanently occupies also has a real cost in a studio.
The honest counter-argument is time. Loading a 4-place-setting machine, running a 29-minute cycle and unloading it takes longer than washing two plates by hand. The dishwasher earns its place when you are generating dishes faster than you want to scrub them — a household of two where both people cook daily, or any home with a baby bottle routine.
Two warnings before you buy. First, watch for white labeling: two brands can sell the identical machine in a different finish under a different badge, which is why near-identical listings across budget brands exist. Compare dimensions, capacity, cycle lists and weight — if they match exactly, it is the same chassis. Second, stay away from any listing that is vague about noise, drying method or faucet compatibility, because those are the three things you cannot discover after delivery.
If you are not sure, a used full-size unit is a reasonable bridge. Forum contributors on r/LivingAlone and r/HomeImprovement recommend buying a used portable or countertop machine when budget is the binding constraint, and because a portable machine can simply be replaced rather than repaired when it fails.
Frequently Asked Questions
What is a good small apartment-sized dishwasher?
A countertop unit holding 4 to 6 place settings with a built-in 5L water tank. The tank means no faucet hookup, no plumbing and no landlord permission, which is the constraint that actually decides the purchase in an apartment. Look for hot air drying or an auto-open door to avoid wet dishes, and check that the machine clears your under-cabinet clearance before ordering.
What is the best brand of dishwasher for a rental apartment?
For a rental, prioritize a brand with a real appliance division behind it so parts and service are easy to find. BLACK+DECKER and COMFEE both fit that description and both offer countertop models that store away when unused. Whichever brand you choose, confirm your lease permits a dishwasher at all, and prefer a tank-fed model that requires no permanent plumbing or installation.
What is the smallest countertop dishwasher available?
The narrowest and most compact machines measure around 16.5 to 16.9 inches wide by 16.7 to 16.9 inches deep, holding 4 place settings. The NOVETE and EUHOMY sit at the compact end of this roundup at roughly 16.8 and 16.7 inches wide respectively, while the largest countertop machines reach 21.7 inches wide. Most need about 18 inches of vertical clearance under cabinets.
Which dishwasher to stay away from?
Avoid any listing that is vague about noise level, drying method or faucet compatibility, since those three cannot be discovered after delivery. Also be cautious with near-identical budget listings that are the same white-label machine in different finishes, and with machines that do not state whether a faucet adapter is included. In apartments specifically, steer clear of anything requiring a permanent water line without written landlord approval.
Do I need a faucet adapter for a countertop dishwasher?
Only if you plan to run the machine in faucet mode rather than filling its built-in tank. Standard fixed faucets with a threaded spout generally accept a standard adapter, but pull-down, retractable hose-style and touch-activated faucets usually do not. Some models include an adapter and some sell it separately, so check the box contents and your faucet type before ordering.
The Best Dishwashers for Small Apartments in 2026
After working through eight machines against the constraints that actually matter in a small kitchen, the Hermitlux takes our Editor’s Choice for the best balance of capacity, program count and a 4,500-plus review history that tells you something real about long-term ownership. Buy it if you want the most evidence-backed option and can clear 18.23 inches of vertical space.
Pick the EUHOMY instead if noise is your binding constraint at 40 dB, the NOVETE if your plates are oversized, the COMFEE 6-place model if you need a full load to fit in one run, and the EdgeStar 18-inch built-in only if you own the apartment and have a narrow bay to fill.
Whatever you choose, measure first. The distance between a machine that fits your counter and one that does not is a single tape measure, and it is the step most people skip.
