A portable dishwasher for renters is a compact countertop or 18-inch machine that washes a small load of dishes without any permanent plumbing or cabinet work. Our overall winner is the Hermitlux 7 Program Countertop Dishwasher, which pairs a 5 liter built-in water tank with the largest review base in the group.
Short answer on the two questions every renter asks first: yes, you can use a portable dishwasher in an apartment, and no, a countertop model does not need plumbing. It runs from a tank you fill by hand or from a temporary faucet connection, then drains back into your own sink. Permission is the separate question, and it comes down to your lease and your building’s rules rather than to the appliance itself.
We compared 10 countertop and portable models side by side for this guide, weighing published footprint measurements, water source, place-setting capacity, noise rating and the failure patterns that show up in owner reviews. If you want the wider category first, our portable dishwasher roundup and countertop dishwasher guide cover the basics of form factor before you measure your own kitchen.
Last updated October 2026. Every capacity, dimension and decibel figure below comes from the manufacturer’s published listing, and we flag specs a brand does not publish rather than guessing at them.

1. Hermitlux Countertop Dishwasher – Best Overall for Renters
Hermitlux Countertop Dishwasher, 7 Washing Programs Portable Dishwasher
5L built-in tank or faucet mode
16.85W x 16.73D x 18.23H inch
50 dB
5 place settings
Pros
- 5 place settings in a compact body
- 5L tank means no faucet and no landlord conversation
- Saves up to 83 percent more water than handwashing
- 14 jet 360 degree spray coverage
- Delay start up to 18 hours
Cons
- Needs 20.08 inches of clearance under wall cabinets
- Large cookware and baking sheets do not fit
- Some water remains in the tub after a cycle
This is the unit I would put in a rental kitchen first. The body measures 16.85 inches wide by 16.73 inches deep and 18.23 inches tall, which is narrow enough for most galley counters, and the 5 liter tank means it never touches the faucet. That last point matters more in a rental than the spec sheet suggests, because a quick-connect hose is a modification to someone else’s sink.
Seven programs cover the range a renter actually uses: Standard, Quick, Strong, ECO, Fruit, Self-clean and Glass, plus delay start up to 18 hours, a child lock and a dry function. With 4,583 reviews averaging 4.4 out of 5, it is the most thoroughly reviewed machine in this group, and owners keep pointing to the same thing: five place settings in a body this size.
Water use is listed at 5 liters per cycle and energy draw at 0.38 kWh, with 60 minutes of hot air drying and 72 hours of automatic ventilation after the cycle.
Check the clearance before you order. Owners report you need 20.08 inches between counter and wall cabinets, more than the 18.23 inch machine height.
What renters like about it
There is no plumbing conversation to have. Fill the tank, press start, then pull the drain hose out of the sink when the cycle ends.
Where it falls short
Five place settings drops by a third once a saucepan enters the rack, so cookware and baking sheets stay in the sink.
2. COMFEE’ 6 Place Setting Countertop Dishwasher – Best Stainless Steel Value
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, up to 70 pieces
Stainless steel interior
19.7D x 21.7W x 17.2H inch
52 dB
Pros
- Largest load in a countertop body at 70 pieces
- Stainless steel tub handles heavy soil better than plastic
- Energy Star certified
- 45 minute Speed cycle uses 2.77 gallons
- Quiet motor for a small kitchen
Cons
- Tap hookup will not fit pull-out or Moen pull-down faucets
- 59 inch hoses may not reach a tucked-away outlet
- Bulky for the number of dishes it holds
- Draining is noisy and drying can spot
This is the capacity leader among countertop machines at 6 place settings and up to 70 pieces, with plates up to 10 inches. The stainless steel interior is the reason it holds up better against baked-on food than the plastic tubs in this group, and 3,735 reviews averaging 4.2 out of 5 make it the second most proven machine here.
Eight cycles run from Heavy through Baby-Care, ECO, Glass and Speed, and the Heavy program uses 12 nozzles with 360 degree spiral spray up to 154 degrees F. The Speed program finishes in 45 minutes using as little as 2.77 gallons per cycle, which is the figure to quote if you are arguing water savings with a landlord.
At 19.7 inches deep by 21.7 inches wide and 17.2 inches tall, this is a wide machine, and the only unit here that fits under standard upper cabinets. Measure the counter width before committing.
It comes with an inlet hose, drain hose and faucet adapter, so you can run it from the tap or fill and drain manually. Both routes work, which helps when a lease says no to fixture changes.
What renters like about it
The stainless tub avoids the odor retention and loose spray-arm coverage owners report with plastic machines, and it holds a full day’s cooking for three.
Where it falls short
Faucet compatibility is the most-cited complaint and the most common return reason in this category. Pull-out and pull-down faucets usually reject the supplied adapter, so buy a tank model instead.
3. COMFEE’ Mini Dishwasher with 1.32 Gallon Tank – Best Budget Pick
COMFEE’ Portable Mini Dishwasher Countertop with 1.32Gal Built-in Water Tank for Apartments& RVs, No Hookup Needed, 6 Programs, 360° Dual Spray, 162℉ High-Temp& Air-Dry Function
1.32 gallon built-in water tank
16.53W x 17.13D x 17.24H inch
62 dB
30 plus items per load
Pros
- True no-hookup tank filling needs only an outlet
- 162F hygiene cycle suits baby bottles
- Compact body fits most small counters
- Quick connect and tank modes both work
Cons
- Interior fits about two place settings in practice
- Pots and pans must be handwashed
- Plastic interior holds odors
- Cycles run past 2 hours on standard and hygiene
The smallest complete unit here, at 16.53 inches wide by 17.13 inches deep and 17.24 inches tall, and it needs at least 19.6 inches between counter and wall cupboard. The 1.32 gallon built-in tank means you fill it from the tap and pour it in, so it works in a studio, a basement suite or a kitchenette with no plumbing.
Six programs cover Normal, Rapid, Hygiene, Fruit and Glass plus Air Refresh drying. The Hygiene cycle heats water to 162 degrees F, high enough for baby bottles, and the 360 degree dual spray arms handle most loads without repositioning.
Its rating profile is the weakest of the well-reviewed units here: 4.0 out of 5 from 3,294 reviews with 15 percent one-star. Complaints cluster around small real capacity, long cycle times, and owners who hit spray-arm or error-code faults within a few months.
This is the pick if your household is one person, or two who do not cook heavily, and counter space is genuinely tight. For three or more, step up a size.
What renters like about it
Location independence is the real feature. An outlet is all it requires, so it works on a folding table in a studio or a dorm. Several renters in apartment forums describe renting one short-term to test the routine before buying.
Where it falls short
Thirty-plus items sounds like a family load, but tight rack spacing means a single pot drops the count sharply. Loading takes practice, and the plastic tub needs degreaser cleaning to stop holding smells.
4. COMFEE’ 6L Tank Dishwasher with Auto-Open Door – Best for Auto-Open Drying
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, manual fill or faucet
16.53W x 17.13D x 18.3H inch
62 dB
Fits 10.5 inch plates
Pros
- Auto-open door with turbofan genuinely dries dishes
- Fits 10.5 inch plates and the largest COMFEE interior
- Timer and delay function suit overnight running
- Low energy draw at 0.35 kWh per cycle
- UV hygiene function and child lock
Cons
- Pouring in several pitchers of water each cycle is a hassle
- Spray arms need careful dish placement
- Filter and interior need cleaning several times a week
- Some owners report an E4 code failure after light use
The distinguishing feature is the auto-open door. At the end of a cycle the door cracks open and a turbofan pushes warm air across the load, so dishes dry without you proping the door and remembering to empty it. For renters with limited drying rack space, that solves a real daily problem rather than a cosmetic one.
It also holds the largest COMFEE countertop interior and accepts a 10.5 inch plate, wider than anything else in this roundup. The 6 litre tank fills by hand or connects to a faucet, using about 60 percent less water than handwashing.
Five wash programs run Normal, Rapid, Hygiene, Fruit and Glass, plus two enhanced functions. Hygiene reaches 162 degrees F for the wash and a 192 degree F maximum rinse, and a UV function, see-through window, child lock and leak protection round it out. Energy draw is 0.35 kWh on a normal cycle.
Rated 4.1 from 3,059 reviews with 67 percent five-star. The gripes are the manual water fill, sensitivity about dish placement around the spray arms, and a few units failing with an E4 code within months.
What renters like about it
The delay and timer functions make it practical to run overnight, so the unit is not standing mid-cycle during a workday. The 10.5 inch plate fit means family dinnerware works without a workaround.
Where it falls short
Filling four pitchers of water by hand every cycle is the deal-breaker for many renters, which is why the faucet route matters even on a tank machine. The drain hose clamp and suction cup are ineffective as supplied, so secure the hose yourself.
5. NOVETE Portable Countertop Dishwasher – Best for Fast Cycles
NOVETE Portable Countertop Dishwashers for Small Apartments
4 place settings, 12 inch dish fit
16.9W x 16.8D x 18.1H inch
50 dB
28 pounds
Pros
- 29 minute Speed cycle is among the fastest here
- 72 hour ventilation keeps stored dishes dry and odor free
- Automatic water level indicator simplifies tank filling
- Lighter at 28 pounds than most rivals
- Dual-layer rack with cutlery and fruit baskets
Cons
- Pots
- pans and large serving items do not fit
- Speed cycle leaves dishes wet
- Plastic tub and racks need periodic manual cleaning
The NOVETE runs a Speed cycle in 29 minutes, which matters when the kitchen is also the living space. The body is 16.9 inches wide by 16.8 inches deep and 18.1 inches tall and weighs 28 pounds, the lightest here, so one person can move it between counter and shelf.
Four full place settings, and it accepts dishes up to 12 inches loaded at an angle. That angled loading lets a compact body take family-size plates, and it is why we would pick this over smaller units for a shared one-bedroom.
Five cycles run Normal, Speed, Soft, Baby Care and Heavy, and Fruit, with Baby Care and Heavy washing at 167 degrees F. The 5 litre tank has an automatic water level indicator, which removes the most common tank-filling mistake.
It is also a dishwasher, dryer and storage cabinet: 60 minutes of hot air drying plus 72 hours of automatic ventilation means you can leave a load inside and unload later. A transparent glass door with an LED lamp shows progress.
What renters like about it
At 4.4 from 2,516 reviews with 75 percent five-star, this has one of the strongest rating profiles here. The 29 minute cycle and 72 hour storage function are the two features owners name most.
Where it falls short
Four place settings is genuinely four, and capacity collapses the moment a saucepan enters the rack. The Speed cycle leaves dishes wet, and the plastic tub needs periodic hand cleaning.
6. HAVA Countertop Dishwasher with Water Softener – Best for Hard Water Areas
HAVA Countertop Dishwasher with Water Softener & Enhanced Energy Efficiency
Integrated water softener,5L built-in tank
16.75W x 16.86D x 18.05H inch
60 dB
13 kg
Pros
- Integrated water softener prevents limescale and water spots
- 8 wash programs including baby-care and heavy soil
- 5L tank needs no plumbing at all
- Redesigned basket holds more than earlier HAVA models
- Lowest one-star share of any unit in the roundup
Cons
- 60 dB is among the louder units here
- Compact interior limits cookware
- Listed at 220 volts which is unusual for a US unit
- Higher energy figure than most in this group
Hard water is the quiet destroyer of small dishwashers. It spots glasses and bowls and builds scale on the heating element, and the HAVA is the only machine here with an integrated water softener and a hardness-based setting. In a hard water region that feature is worth more than an extra wash program.
The body is 16.75 inches wide by 16.86 inches deep and 18.05 inches tall. The 5 litre built-in tank means no plumbing and no landlord involvement, and eight wash programs run through a touch screen with a child lock and 18 hour delayed start.
Its rating distribution is the most favorable here: 4.3 from 1,906 reviews with 69 percent five-star and 3 percent one-star, the lowest negative share we found. Owners credit the water softener and the redesigned adjustable basket.
Two notes before you order. It is listed at 220 volts, unusual for a US countertop unit, so check what the plug expects. It is also among the loudest here at 60 dB.
What renters like about it
The rack redesign holds more than earlier HAVA models, and the 360 degree pattern covers the interior without a lot of plate angling. Delayed start means you can run it while you are out.
Where it falls short
At 60 dB this starts conversations in an open-plan kitchen. The compact interior limits cookware, and a plug mismatch in a rental means an electrician and possibly a landlord call.
7. BLACK+DECKER BCD6W Countertop Dishwasher – Best for Bigger Loads
BLACK+DECKER Countertop Dishwasher, Energy Star Certified, BCD6W, White
6 place settings, stainless interior
21.5D x 21.7W x 17.2H inch
60 dB
46.2 pounds
Pros
- Largest capacity in the roundup
- fits mixing bowls and processor parts
- Recognizable brand with a real service network
- Multiple short cycles including a 45 minute wash
- Child lock and 24 hour delay start
- Energy Star certified
Cons
- Quick connect will not work with pull-out sprayer faucets
- 5 foot hoses often too short for a tucked-away install
- Weak drying without rinse aid
- 46.2 pounds is hard for one person to lift
If a shared apartment generates more than a couple of plates a day, capacity decides it, and this is the machine to look at first. Six place settings in a 21.5 by 21.7 by 17.2 inch body is the largest rack here, and owners specifically mention mixing bowls and processor parts fitting.
The stainless interior handles baked-on residue better than plastic, and seven cycles give real options: Normal, Intensive, Eco, Glass, 90 Minutes, Rapid and Soak. The 45 minute wash handles a normal load, and the LED display shows remaining time with delay start to 24 hours.
It is Energy Star certified and uses a quick-connect faucet assembly with no permanent plumbing. Rated 4.2 from 1,340 reviews with 69 percent five-star, and a familiar brand name matters when something goes wrong in a rental.
The complaints are practical. Quick-connect will not work with pull-out sprayer faucets without extra parts, the 5 foot hoses are often too short for a tucked-away position, and drying is weak without rinse aid. At 46.2 pounds, plan the lift.
What renters like about it
It fits under standard upper cabinets, which almost nothing else here manages, and it doubles as storage between uses. The stainless tub and seven genuine cycles mean you are not choosing between fast and thorough.
Where it falls short
At 21.7 inches wide it is the biggest footprint here, and 46.2 pounds is a two-person lift. A few owners report E4 failures and refurb replacements inside the warranty period, so register the unit on arrival.
8. EUHOMY 40dB Stainless Steel Dishwasher – Best for Open-Plan Apartments
EUHOMY 6 Programs Countertop Dishwasher Portable, 40dB, 360° Coverage
40 dB operation
16.73W x 16.85D x 18.03H inch
5L tank
30 plus dishes
Pros
- Quietest unit in the roundup at 40 dB
- Highest rating at 4.5 out of 5
- 5L tank with level indicator avoids any faucet work
- 29 minute fast cycle
- ETL and DOE certified stainless interior
Cons
- Too tall for many standard under-cabinet spaces
- Utensil holder slots are poorly spaced
- No enclosed detergent compartment
- Pre-rinsing needed for the cleanest results
When the kitchen is also the living room, noise is not a nice-to-have. At 40 dB this is the quietest machine here and also the highest rated at 4.5, plus it holds the number one Best Sellers Rank in countertop dishwashers.
The body is 16.73 inches wide by 16.85 inches deep and 18.03 inches tall, with a 5 litre built-in tank and a G3/4 inch inlet hose if you prefer the tap. The interior is stainless steel, it is ETL and DOE certified, and it washes 30 plus dishes with plates up to 10.25 inches.
Six programs run Normal, Fast, Glass, Baby Care and Heavy Duty, Fruit and ECO. Fast finishes in 29 minutes, Baby Care and Heavy boils water to 167 degrees F, and drying gets 60 minutes of hot air plus 73 hours of ventilation.
From 1,004 reviews, 78 percent are five-star, the highest share here. Owners single out quiet running, tank-only convenience and cleaning power. The complaints: too tall for many under-cabinet spaces, poorly spaced utensil slots, no enclosed detergent compartment.
What renters like about it
Silence is the headline. A 40 dB machine in a studio or open-plan one-bedroom is unobtrusive, and 73 hours of ventilation means a clean load stays dry while you find cupboard space.
Where it falls short
Height is the constraint. It needs more than 19 inches of vertical clearance, so with low wall cabinets this is a counter machine only. Heavily soiled dishes also need a pre-rinse.
9. Midea Countertop Dishwasher with Baby Care Tank – Best for Baby Bottles
Midea Countertop Dishwasher with 1.32Gal Tank, Baby Care, 5+1 Programs
1.32 gallon built-in tank
16.63W x 17.5D x 17.5H inch
62 dB
5 plus 1 programs
Pros
- Backed by a major appliance brand with a one year warranty
- Dedicated baby bottle holder is a genuinely useful accessory
- 1.32 gallon tank fills quickly and needs no plumbing
- Glass viewing door and LED display show cycle progress
- Improved drying over earlier versions
Cons
- 62 dB is one of the loudest units here
- Compact interior limits dishes per load
- Highest one-star share in the roundup at 14 percent
- Push button controls are less precise than touch panels
This is the pick for a rental with a newborn. The 1.32 gallon built-in tank means no plumbing, and the included baby bottle holder keeps bottles inverted and pacifiers secure so the high-temp wash reaches the inside. Five programs plus one enhancement cover Baby Care, Delicate, Normal, Quick and Fruit.
Water use is listed at 1.3 gallons per cycle, which the brand puts at up to 60 percent less than handwashing. A glass viewing door shows progress without breaking the seal.
It is 16.63 inches wide by 17.5 inches deep and 17.5 inches tall, so it fits most counters without a tall-cabinet problem. A major brand behind it matters when a rental deposit is at stake.
Be aware of the rating profile: 4.0 from 760 reviews with 14 percent one-star, the highest negative share here. Noise at 62 dB is the other flag, alongside a compact interior and push-button controls.
What renters like about it
The bottle holder solves a specific nursery problem rather than a general one, and the tank fills fast enough that bottle washing is not a chore.
Where it falls short
At 62 dB it is loud, and in a thin rental wall you hear it in the next room. The interior is small, so handwash anything that is not a bottle, plate or cup.
10. EUHOMY 8 Program Countertop Dishwasher – Best for Self-Clean Mode
EUHOMY Countertop Dishwasher Portable, 8 Programs with 5L Tank, Black, 40dB
8 programs with self-clean cycle
16.85W x 16.73D x 18.03H inch
40 dB
5L tank
Pros
- 40 dB operation in an open-plan kitchen
- Self-clean maintenance mode few rivals offer
- 5L tank with level indicator makes it location independent
- Dual spray arms give 360 degree coverage
- Attractive glass door design for visible placement
Cons
- Newest listing with the smallest review base at 284 reviews
- Drying leaves water pooled on cups and bowls
- Inlet hose kinks when pushed back against a cabinet
- Interior light times out after a couple of minutes
This is the more complete of the two EUHOMY machines. It runs 8 programs where the 40 dB model runs 6, and the addition that matters in a rental is Self-Clean, a maintenance cycle for the interior and spray arms. In a kitchen you do not own, a self-cleaning machine earns its keep.
Size is near-identical to its sibling: 16.85 inches wide by 16.73 inches deep and 18.03 inches tall, needing more than 19 inches of vertical clearance. The 5 litre tank works with a G3/4 inch faucet hose, and the level indicator removes the guesswork.
Programs run Normal, ECO, Quick, Baby Care and Strong, Glass, Fruit, Self-Clean and Dry. Quick finishes in 29 minutes, Baby Care and Strong reaches 167 degrees F, and dual spray arms handle coverage. It is ETL and DOE certified with a 1 year warranty.
It holds 4.5 from 284 reviews with 77 percent five-star, but that is a much thinner evidence base than the machines above it. Owners praise quiet running and self-clean mode; the gripes are pooled water after drying, a kinking inlet hose and an interior light that times out.
What renters like about it
Self-clean plus hot-air drying make it the lowest-maintenance option here, and the glass door looks good enough to leave on an exposed counter.
Where it falls short
With 284 reviews, long-term reliability is not established the way it is for the Hermitlux or COMFEE 6 place setting machine. Drying is a recurring complaint, and the inlet hose needs careful routing.
Do You Need Your Landlord’s Permission for a Portable Dishwasher?
A portable dishwasher is almost always legal in an apartment. What is not always legal is a lease clause, a building rule, or a fixture change. Check these five things before you order, and you will know within ten minutes whether you have a problem.
First, read the lease for language on appliances, alterations and water damage liability. Second, check your building’s rules or resident handbook, which often carry stricter terms than the lease itself. Third, ask whether any fixture change is involved, because a quick-connect adapter on someone else’s faucet is technically a modification even though it takes two minutes and no tools.
Fourth, look at your renter insurance. Personal liability cover usually extends to water damage you cause, but exclusions vary, and a dishwasher that overflows a floor you do not own is exactly the claim scenario people discover too late. Fifth, confirm the exit plan: whether the unit leaves with you at move-out, and whether leaving it behind affects your deposit.
On the plumbing question specifically, commenters on r/AskNYC describe countertop dishwashers as harmless to an apartment’s plumbing, because they use less water than hand washing and drain into the sink you already own. Users on the Ars Technica forum warn instead that the machines themselves are a chore to get hooked up correctly, which is an argument for a tank-only model.
If your lease is silent, send a short written note to your landlord describing the model, its footprint and that no plumbing is altered. Renters on the Glassdoor community forum report that asking for a dishwasher installation can trigger a rent increase once the unit is upgraded, so keep your request to a portable appliance you remove yourself. If you are still unsure, renting one short-term first is the cheapest way to test whether you even like the routine.
Countertop vs 18-Inch Freestanding: Which One Fits a Rental
For a rental, a countertop unit is the right default. A full 18-inch freestanding machine needs a floor space, a water line and a drain connection, which is a landlord conversation rather than a purchase. The smallest countertop units in this roundup start at 16.53 inches wide, and the largest stop at 21.7 inches.
Measure three numbers before you order, not the machine’s listed width. First, the width of the counter run where it will live. Second, the depth available with the door fully open, because loading a rack with the door at right angles usually needs more depth than the published figure. Third, the vertical gap between the counter and any wall cabinet, since several units here need 19 to 20 inches of clearance even though their own height is under 18.3 inches.
If the vertical gap fails, you have three realistic options: clear out an under-cabinet shelf and store the machine there between uses, keep it on the counter permanently, or run it from a rolling cart beside the sink. The rolling cart option is the one renters with low cabinets report using most, and it keeps the counter clear.
One more galley-specific warning: if the dishwasher becomes your only counter surface, you have nowhere to stage clean dishes. Our broader dishwasher buying guide covers rack layout in more detail, but the rule of thumb is to leave yourself at least 18 inches of clear counter beside the machine.
Faucet Hookup vs Built-in Water Tank: Do Countertop Dishwashers Need Plumbing?
No, countertop dishwashers do not need plumbing. Every unit in this roundup works from a built-in water tank that you fill from the kitchen tap and empty into the sink, and most also accept a temporary faucet connection through a quick-connect adapter and drain hose. Nothing is permanently plumbed and nothing has to be removed at move-out beyond putting the adapter back.
The trade-off is honest in both directions. Faucet hookup is more convenient, because you stop carrying water, and it draws fresh supply continuously. Tank filling is more portable and more renter-friendly, because it works with any outlet and never touches another person’s fixture. The cost is the pitcher ritual, which owners of the 6 litre models describe as several pitchers per cycle.
Check your faucet before buying any hookup model. Pull-down and pull-out sprayer faucets, and most touchless or sensor faucets, will not accept a standard quick-connect adapter, and this is the most common return reason across the whole category. If your faucet is one of those, a tank model is the correct purchase and no workaround will change that.
Whatever route you pick, secure the drain hose. Several owners report that the supplied clamp and suction cup are ineffective, and a hose that slips out of a sink full of dirty water is the one failure mode that turns a renter’s dishwasher into a deposit problem. Clip it to the sink rim or secure it to the cabinet before the first cycle.
Noise in an Apartment: Why 40-45 dB Matters
Ratings in this roundup run from 40 dB on the two EUHOMY machines up to 62 dB on the Midea and the 5 litre COMFEE models. Perceived loudness roughly doubles for every 10 dB, so the difference between a 40 dB and a 50 dB machine is not a rounding error, it is the difference between a background hum and something you notice in the next room.
Our read is that anything at 50 dB or below works in a normal apartment, and 60 dB or above becomes a conversation topic in a thin-walled rental. If you rent a top-floor unit with concrete between you and the neighbour below, noise is much less of an issue than the walls in the same building suggest.
For multi-unit buildings, run the machine on a delay start while you are out. Renters in an r/AskChicago thread describe downstairs neighbours complaining about noise and reduced water pressure when a tenant runs a dishwasher at odd hours, which is a dispute that is far easier to avoid than to resolve.
How to Choose a Portable Dishwasher for Renters
Start with capacity, and translate it honestly. One place setting means one dinner plate, one side plate or bowl, one glass, one cup and saucer, and one set of cutlery, roughly ten items. A machine advertised at 6 place settings that also accepts a 10.5 inch plate can realistically handle a full evening for two people plus a little, or one day of cooking for a household of three.
Next, pick your water source honestly. Tank-only is the right answer if your lease is unclear, your faucet is pull-down or touchless, or you want the machine to move between rooms. Faucet hookup is the right answer if carrying water every day will annoy you more than a five-minute adapter install and a landlord email.
Then work out the running cost against hand washing. The published figures in this group are 5 litres per cycle for the Hermitlux, 6 litres for the 6 litre COMFEE, and 2.77 gallons on the COMFEE Speed cycle, with energy draw listed as low as 0.35 to 0.38 kWh on a normal cycle. Manufacturers put savings at 60 to 83 percent against hand washing. Hand washing a similar load typically uses far more water than a five litre cycle, and the detergent pod cost per cycle is the only number you fully control.
Budget separately for the things a countertop dishwasher cannot do. Cast iron, wooden items, insulated drinkware, cutting boards and sharp knives stay out, and none of these machines has an interior cabinet large enough for cookware. The real capacity in any of them drops by a third the moment a saucepan goes in.
For maintenance, expect to clean the filter, wipe the spray arm and check the door seal every week or two, and descale on a schedule in hard water. A machine you own for three years in someone else’s property needs more attention than one in your own home.
Finally, run a leak watch on your first three cycles. Put a dry paper towel under the drain hose, under the tank connection and behind the machine before you start, then check at the end of each cycle. A countertop unit uses 5 to 6 litres, so a failure is contained, but only if you catch it early.
On move-out, a portable unit leaves with you and your deposit is unaffected, since nothing was plumbed in. That is the practical argument for a portable machine over asking a landlord to install anything.
Frequently Asked Questions
Can I use a portable dishwasher in an apartment?
Yes, a portable dishwasher is legal in an apartment in most cases because it requires no permanent plumbing or cabinet work. The thing that can stop you is a lease clause or building rule about appliances, alterations or water damage, so check those before ordering. If your lease is silent, send your landlord a short written note describing the model and its footprint.
Do countertop dishwashers need plumbing?
No. Every countertop dishwasher runs from a built-in water tank that you fill by hand and empty into your own sink. Most also accept a temporary faucet connection through a quick-connect adapter and drain hose, which is removable at any time. Pull-down, pull-out and touchless faucets usually reject a standard adapter, so a tank-only model is safer in those kitchens.
Do portable dishwashers work well?
They work well for plates, cups and cutlery, which is the majority of a typical load. They do not replace a full-size machine for cookware, and real capacity drops sharply once a saucepan enters the rack. Published reviews in this group average 4.0 to 4.5 out of 5, with the main complaint categories being small capacity, drying and faucet compatibility.
Is it illegal to have a portable dishwasher in an apartment?
No, there is no general law against it. Legality comes down to your lease, your building’s rules and your renter insurance terms. A lease can restrict appliances or require landlord approval for alterations, and a quick-connect adapter on the kitchen faucet can count as a modification. Permission in writing removes the dispute later.
How loud is a portable dishwasher?
Units in this roundup are rated between 40 and 62 dB. Because perceived loudness roughly doubles for every 10 dB, a 40 dB machine is a background hum while a 62 dB machine is audible in the next room. For a studio or an open-plan apartment, stay at 45 dB or below and use the delay start function.
Will full-size plates fit in a portable dishwasher?
It depends on the model. The 6 litre COMFEE accepts 10.5 inch plates, the EUHOMY machines take plates up to 10.25 inches, and the NOVETE fits 12 inch dishes when they are loaded at an angle. The smaller units top out around 9.5 inches. Check the published maximum plate diameter before you order, especially if you cook for more than one person.
Best Portable Dishwashers for Renters: The Verdict in 2026
The Hermitlux 7 Program Countertop Dishwasher is our pick for the best portable dishwashers for renters, because it combines a 5 litre no-hookup tank, five place settings and the largest review base in the group. Pick the COMFEE 6 place setting machine if you need a stainless tub and bigger loads, the two EUHOMY models if noise is your problem, and the 6 litre COMFEE if you want dishes dry without touching them afterward.
Before any of them goes through the door, check your lease, measure the depth with the door open, and look at your faucet. Those three steps prevent almost every return and every argument.
