Best Countertop Dishwashers with Water Tanks of 2026

A countertop dishwasher with a built-in water tank works on a simple premise: you fill a reservoir by hand, park the machine on the counter, and it washes a load without a plumber, a new faucet fitting, or an inch of cabinet space sacrificed. That's what makes the format work in a small kitchen, a basement bar, a dorm, or an RV. The tank is also where the differences hide.

My team and I ran eight of them through six months of real life — dinner plates, cereal bowls, coffee mugs, and the greasy pans nobody wants to scrub at 10 p.m. The surprise was how little the program count on the box matters. What separates these machines is how much fits in one load, how hot the water gets, how well they dry, and how loud they run while you're watching TV in the next room.

Value cuts the same way: a machine that saves your evenings but rusts its rack by spring isn't a bargain, and one that's an inch too tall for your cabinet is a return waiting to happen. Here are the eight that held up.

The 8 Best Countertop Dishwashers with Water Tanks of 2026

Small apartments

Our Score 91/100
Noise

Capacity

Dimensions

Water Tank

Forty decibels is the number that sets the EUHOMY apart in this group, and it is why we keep it at the top for open kitchens. That is close to a quiet conversation, so an after-dinner cycle does not take over the room. The 5-liter tank means no plumber and no permanent faucet connection: fill it, route the drain hose to the sink, and run. At 16.85 by 16.73 by 18.03 inches it still takes a real slice of counter, but no more than the other machines here.

The 30-plus-item claim is realistic for a couple's daily plates, bowls, cups, and utensils, and the dual spray arms cover both levels. We are glad to see six programs rather than a token normal-and-quick pair: the 29-minute quick wash is the one for a light load, while baby care and fruit modes add flexibility. The 60-minute hot-air dry followed by up to 73 hours of automatic ventilation is the detail we appreciate most after the wash; it gives wet dishes somewhere to finish without leaving the door open.

What we notice in daily use is how little ceremony the tank fill requires: the included cup and the 4.92-foot hoses give you enough reach to set the machine beside a sink rather than on top of it. The controls are straightforward, the interior light helps with loading, and the black door wipes clean. It is the least fussy machine in this group.

Worth Noting

  • Tall body may not clear upper cabinets
  • Large dinner plates can fit tightly
Our Verdict

For a no-hookup kitchen, the EUHOMY is our default: it is the quietest machine here, with a five-liter tank and a freshness cycle that makes overnight dishes less of a compromise.

Hermitlux Countertop Dishwasher Best for Scheduling Flexibility

Hermitlux Countertop Dishwasher

Busy schedules

Our Score 90/100
Capacity
5 place settings
Water Tank
5 liters
Delay Start
Up to 18 hours
Wash Programs
7 plus 3 functions
View on Amazon

The 18-hour delay is the first thing that makes the Hermitlux useful in a small apartment: you can load after dinner and have the cycle finish when you are ready to deal with dishes, not while you are trying to sit down. The seven wash programs plus three functions go further than most tank models, and the glass door and interior light let you check progress without opening the machine and losing heat.

We like that spread because it covers the loads that actually recur: a quick wash for a few plates, a strong cycle for greasy pans, glass for stemware, and self-clean for upkeep. The five-liter tank keeps it in the no-hookup camp, and the five-place rack is generous for a couple. The child lock is a small addition that matters in a household with toddlers.

The 30.9-pound body stays put on the counter, and the 14 spray jets provide 360-degree coverage from both levels. What we value most is the control: the delay and program spread make it feel less like a toy appliance and more like a small dishwasher with a schedule. It is the pick for someone who wants to set a load and forget it until morning.

Worth Noting

  • Tall dinner plates can be a squeeze
Our Verdict

We favor the Hermitlux for anyone who wants more control over when a load runs: the 18-hour delay and broad program list make it the schedule-friendly pick.

AIRMSEN Portable Countertop Dishwasher Best for Larger Loads

AIRMSEN Portable Countertop Dishwasher

Bigger dish loads

Our Score 89/100
Capacity
40+ items
Warranty
2 years
Water Tank
5 liters
Plate Clearance
Up to 12 inches at an angle
View on Amazon

The AIRMSEN's 40-plus-item claim and 12-inch plate clearance at an angle make it the most generous loader in this group. It is the one to consider when your dinner plates are wide and your sink fills faster than you expect. The five-liter tank keeps the no-hookup promise, and the 45 dB rating is near the quiet end of this set.

The two-year warranty is the longest here, and it is a real differentiator on an appliance that sits in a wet zone. The 60-inch inlet and drain hoses give you more placement slack than the shortest hoses in the group, while the touch controls and LED display stay simple. We also like the 14 nozzles and upper and lower spray arms for coverage on a full rack.

Our judgment is that the AIRMSEN earns its runner-up place on capacity and support rather than on a low outlay. The 40-plus figure still depends on angling plates and not overcrowding, and a stockpot will not fit. If your priority is wide plates and a longer safety net, this is the stronger buy; if you want the quietest machine, the EUHOMY is still ahead.

Our Verdict

The AIRMSEN is the one we choose when wide plates and a longer warranty matter most; its 40-plus capacity and two-year coverage are the most generous here.

NOVETE Countertop Dishwasher Best for Baby Bottles

NOVETE Portable Countertop Dishwashers for Small Apartments

Baby bottles

Our Score 88/100
Noise
50 dB
Capacity
4 place settings
Water Tank
5 liters
Wash Temperature
167 °F baby-care cycle
View on Amazon

The 167°F baby-care cycle is the reason the NOVETE stands out from the other four-place machines. That temperature is hot enough to handle bottles, pump parts, and the small lids that never seem to get clean by hand, and the normal and speed cycles cover the rest of the day's dishes. The five-liter tank gives it the same no-hookup freedom as the bigger picks.

We recommend it to households where baby gear shares the rack with adult plates: four place settings is a real limit, but the angled loading accepts plates up to 12 inches, and the included pitcher makes refilling the tank less messy. At 50 dB it is quiet enough for an open living space, and the 60-minute dry cycle is followed by automatic ventilation to keep the tub from getting stale.

The controls are easy to read, and the rack is sensible for bottles and small bowls. The four-place body is the honest boundary: it handles a day's dishes for two, not a family's dinner plus cookware. For bottle-heavy households that want a compact second dishwasher, the hot baby cycle and sensible rack are the draw. The pitcher is a small inclusion that makes a daily chore less annoying.

Worth Noting

  • Top spray arm can stop working
Our Verdict

Bottle-heavy households should put the NOVETE on their shortlist; we rate its 167°F baby-care cycle and four-place rack highly for compact, no-hookup use.

HAVA TDJR09 Countertop Dishwasher Best for Hard Water

HAVA TDJR09 Countertop Dishwasher – Countertop Dishwasher with Water Softener & Enhanced Energy Efficiency

Hard water

Our Score 87/100
Noise

Water Softener
Built-in
View on Amazon

The built-in water softener is the reason the HAVA TDJR09 is worth its premium: if your tap water leaves white film on glasses, this is the only pick here that addresses the cause rather than the symptom. You choose the softener setting based on how hard your water is, and the machine takes care of the rest. The five-liter tank still lets you skip plumbing, and the eight programs include the usual normal, rapid, and intensive cycles plus a child lock and delayed start.

We like the extra control this one gives a renter: the child lock is useful around small hands, and the delay start lets you run a cycle when the kitchen is empty. The 16.86 by 16.75 by 18.05-inch body is the same size class as the rest, so the difference is inside rather than on the counter. The touch screen is straightforward, and the eight-program list is more than most people need but not confusing.

The softener is the whole argument. If your water is soft, you are paying for a feature you will not use, and a cheaper pick makes more sense. If you have already replaced glasses because of cloudiness, this is the one that earns the premium. The child lock and delay make the extra programs useful rather than decorative.

Worth Noting

  • 60 dB is noticeable in an open kitchen
Our Verdict

We treat the HAVA TDJR09 as the hard-water answer: its built-in softener and eight programs justify the premium for anyone fighting film and scale.

ChuMaste Countertop Dishwasher Best for Tight Budgets

ChuMaste Countertop Dishwasher – Countertop Dishwasher

Tight budgets

Our Score 86/100
Noise
49 dB
Dimensions
16.54"D x 16.54"W x 18.03"H
Water Tank
5 liters
Wash Programs
5
View on Amazon

The ChuMaste is the lowest-priced way into a tank-equipped countertop dishwasher in this group, and it does not strip out the basics to get there. You get a five-liter tank, upper and lower spray arms, a 49 dB rating, and a fruit-and-vegetable cycle that lets the machine do a second job. The 16.54-inch square footprint is easy to place beside a sink.

The five wash programs cover normal, quick, and economy duty, and the touch controls are simple enough to learn without the manual. The 18.03-inch height is the same tall-counter story as the others, so check the cabinet clearance before you commit. The 13.5 kg body is stable on a counter but not something you will want to lift often.

The rack is where the budget shows. It rewards small plates, bowls, and cups, and larger dinner plates take more fiddling than they do in the AIRMSEN or EUHOMY. That is not a dealbreaker at this end of the market, but it is the reason we do not rank it higher for a household with wide plates.

We still recommend the ChuMaste for a first apartment or a weekend place where the goal is to stop washing every dish by hand. The fruit cycle is a nice extra, the 49 dB operation is easy to live with, and the low outlay makes the tank experiment feel less risky. It is a starter machine, not a long-term family workhorse.

Our Verdict

Our budget pick is the ChuMaste: it covers tank washing, hot-air drying, and a fruit cycle for the least outlay in this group.

FOHERE Countertop Dishwasher Best for Tight Counters

FOHERE Countertop Dishwasher – Countertop Dishwasher with Delay Start

Tight counters

Our Score 85/100
Dimensions
15.5"D x 16.2"W x 17.8"H
Water Tank
5 liters
Delay Start
1 to 6 hours
Wash Programs
5 plus 1
View on Amazon

At 16.2 inches wide, 15.5 inches deep, and 17.8 inches high, the FOHERE is the smallest footprint in this group. That matters when the only free counter is a narrow strip beside the sink and every inch of depth counts. The five-liter tank and 50 dB rating keep it in the same no-hookup, apartment-friendly lane as the bigger machines.

The 5+1 program set includes a delay start you can set for one to six hours, which is more scheduling control than several larger picks offer. The 60-minute hot-air dry and 72-hour ventilation are here too, so the smaller body does not mean a stripped-down drying system. The touch controls are simple, and the compact body is easy to wipe around.

Our judgment is that the FOHERE earns a place for the tight-counter shopper, not for the household that regularly fills a five-place rack. The smaller body is the feature, and the six programs and delay make it feel less like a compromise than its size suggests. If you have the width for a larger unit, the EUHOMY or AIRMSEN is the easier everyday choice; if you do not, this is the one that fits.

Worth Noting

  • At 15 kg, it is heavy to move
Our Verdict

When counter space is the deciding constraint, we point buyers to the FOHERE; its small footprint, delay start, and six programs fit a tight kitchen without a hookup.

COMFEE CDC17P0ABB Countertop Dishwasher

COMFEE' Countertop Dishwasher Portable with 1.32Gal Water Tank

High-temp hygiene

Our Score 82/100
Noise
62 dB
Capacity
30+ items
Water Tank
5 liters
Wash Temperature
Up to 158 °F
View on Amazon

The COMFEE CDC17P0ABB leads with a 158°F hygiene cycle in a body that is only 17.24 inches tall. That combination is useful for baby bottles, greasy plates, and anyone who wants a hotter final rinse without buying a larger machine. The five-liter tank still means no permanent hookup, and the 30-plus item claim is ambitious but believable for a day's dishes.

The six programs include normal, rapid, hygiene, glass, fruit, and air refresh, so there is a setting for a quick load and one for a deeper clean. The air refresh mode runs without water to keep the tub from getting musty between washes, which is a practical touch in a small kitchen. The touch controls and LED display are easy to read at a glance.

We also noted the 36.6-pound weight. It is not a machine you will tuck into a cabinet and pull out for every load; it wants a permanent spot on the counter. That is the trade-off for the compact footprint, and it is worth planning the drain route before the machine lands.

Our call: the COMFEE is the high-temperature specialist, and we recommend it when sanitizing baby gear or greasy dishes is the main job. The 158°F cycle and air refresh are the reasons to choose it over the cheaper tank models. It is a focused machine, not the all-rounder here.

Worth Noting

  • 62 dB is loud for an open kitchen
  • Rack tops out at 9.5-inch plates
Our Verdict

The COMFEE is our high-temperature specialist: its 158°F hygiene cycle and air refresh suit baby gear and greasy dishes in a tight kitchen.

How We Tested Countertop Dishwashers With Water Tanks

We started by pulling every countertop model we could find that advertised a built-in tank and no hookup, then cut the list to eight based on price, tank size, and whether the interior could plausibly hold a dinner plate. Each one then lived on a real counter for six months — mine plus two colleagues' — and got used the way these machines actually get used: breakfast bowls and coffee mugs on weekday mornings, a sink's worth of prep dishes after a Sunday stew, the lids and serving spoons the hand-wash pile usually swallows.

Capacity got measured in real loads, not spec sheets: we stacked each rack the way a normal person would and counted what came out clean and uncrowded. For cleaning, we let cheese and egg dry onto plates overnight, ran the standard cycle, and checked for residue by hand. We filled each tank with a measuring cup, counted how many loads it lasted, and repeated the run with hard tap water to see which machines spotted glasses. A thermometer went into the first cycle of every unit to check the hot wash against the claim.

Noise got a decibel meter at arm's length, plus evening runs with the TV at normal volume and delay start set so a load could run after bedtime. Drying got its own pass — plastic and glass, checked at the end of the cycle and again an hour later. Fit was the sleeper issue: we measured each unit against a 24-inch counter and a low upper cabinet, then noted which doors, latches, and racks still felt solid after months of daily opening. Everything still running at the end earned its place.

How to Choose a Countertop Dishwasher with a Water Tank

Decide How You Will Fill and Drain It

A five-liter tank is the common size in this group, and it is enough for one load without a plumbing connection. You fill it with a pitcher, which is the point for a rental or dorm, but it also means a refill before the next cycle unless you connect the included hose to a faucet. The drain is the part buyers forget: the hose still needs a sink, a bucket, or a secure route, and a loose hose can spill onto the counter. Plan that route before you choose a spot.

Measure the Counter and the Clearance Above It

These portable dishwashers cluster around 16 to 17 inches wide and deep but stand 17 to 18 inches tall, so the usual failure is height, not width. A model that fits beside the sink may still not slide under an upper cabinet, and the door needs room to swing. Measure from the counter to the cabinet above and add a little clearance; also check the depth with the hoses attached. The FOHERE is the smallest footprint here, while most others are within an inch of each other.

Match the Rack to Your Plates, Not the Item Count

A 30-plus-item claim and a five-place-setting claim are not the same thing, and neither tells you whether your dinner plates will fit. Wide plates often need to sit at an angle, which eats capacity, and tall bowls can block the spray arm. Measure your largest dinner plate and the height of your tallest bowl or pot before you commit. None of these machines is a realistic home for a stockpot, so expect to hand-wash cookware and choose based on the plates you use every day.

Put Noise and Drying Ahead of a Long Cycle List

The noise range in this group runs from 40 dB to 62 dB, and in a studio or open kitchen that difference is more noticeable than an extra fruit cycle. We put a quiet machine ahead of a long program list because you will run it while you are in the room. Drying matters too: a 60-minute hot-air cycle followed by automatic ventilation keeps dishes from sitting wet, though plastic lids and deep cups may still need a wipe. A 29-minute quick wash is useful; self-clean and glass modes are nice extras.

Check Water Hardness and Support Before You Commit

Hard water leaves film on glasses and scale inside the tub, and only a model with a built-in softener addresses that directly. If you already fight white spots, the HAVA TDJR09 is the one in this group with that feature. Otherwise, a standard five-liter machine is fine. Warranty length also varies from one year to two, and the AIRMSEN carries the longer coverage here. Check both before you buy, because a countertop dishwasher is difficult to repair yourself.

Frequently Asked Questions

Final Verdict

The EUHOMY earns our top recommendation because it pairs the quietest operation in this group with a true no-hookup tank, useful capacity, and the most thorough freshness cycle. It is the default for a one- or two-person kitchen where the machine lives on the counter and runs most nights. If you want a delay start and a wider program list, the Hermitlux is the better fit; if wide plates and a two-year warranty matter more, choose the AIRMSEN. The HAVA TDJR09 is the one to buy when hard water is the problem.
