Living in a small apartment without a built-in dishwasher does not mean you have to wash every plate by hand.
A countertop dishwasher with a built-in water tank can sit on your counter, plug into a standard outlet, and run without a permanent water hookup. You fill the tank from the top, place the drain hose in the sink, and start a cycle.
That makes these compact dishwashers especially useful for renters, studios, RVs, dorm-style kitchens, and older apartments where changing the plumbing is not practical.
For this guide, we compared current models based on countertop dimensions, water-tank capacity, dish capacity, wash programs, drying features, and how practical each design appears for a small kitchen.

How We Chose
For Small Space Scout, countertop size matters just as much as the number of wash programs.
We prioritized models that can operate from their own water reservoir, because that is the feature that makes them especially useful for renters and kitchens without a convenient faucet connection.
We also compared width, depth, height, dish capacity, drying features, manufacturer support, and whether the machine offers something meaningfully different from the other options.
We have not personally hands-on tested every dishwasher in this guide. Our recommendations are based on manufacturer specifications and each model’s suitability for specific small-space situations.
1. HAVA R01 — Our Top Pick for Most Small Apartments
The HAVA R01 is a straightforward option for people who want a compact dishwasher without modifying their kitchen plumbing.
It measures approximately 16.9 inches long, 16.9 inches wide, and 18.1 inches high. HAVA lists a 5-liter built-in water tank, two place settings, five wash cycles, hot-air drying, and extended ventilation after a wash. You can fill the tank manually or connect the dishwasher to a faucet if you prefer.
Its footprint is relatively balanced: it is not unusually wide or unusually deep, which makes it easier to place on many apartment counters.
Another useful detail is the plate capacity. HAVA says the R01 can accept plates up to about 10.24 inches vertically, or up to roughly 11 inches when angled.
Why it works for small spaces: You get a self-contained water tank, compact dimensions, dual water-supply options, and drying without moving into a much wider machine.
What to consider: Two place settings are more appropriate for one or two people than for a household producing a large number of dishes every day.
Best for: renters, couples, solo cooks, and apartments that need a simple no-plumbing solution.

2. COMFEE 5L Countertop Dishwasher — Best for High-Temperature Cleaning
The COMFEE CDC17P0ABB is another compact model with a built-in tank, but one of its more notable features is its manufacturer-listed high-temperature cleaning.
COMFEE lists dimensions of approximately 16.53 inches wide, 17.13 inches deep, and 17.24 inches high, along with a 5-liter water tank, two-place-setting capacity, and 120-volt operation. The current product page also lists high-temperature cleaning reaching up to 192°F.
That relatively short 17.24-inch height may also matter if you are trying to fit a dishwasher beneath upper cabinets.
The machine is designed for manual tank filling, so you do not need a permanent water hookup for normal use.
Why it works for small spaces: The body stays under 18 inches in each major dimension, and the built-in tank removes the need to occupy your faucet during every wash.
What to consider: Its two-place-setting capacity means it is still a small-load dishwasher. Large cookware may need to be washed separately.
Best for: one- or two-person households that want a compact unit with a high-temperature wash option.

3. AIRMSEN TDQR03 — Best for Noise-Conscious Apartments
If your kitchen is close to your living room or sleeping area, operating noise becomes more important than it might be in a larger house.
AIRMSEN lists the TDQR03 at 45 dB, with dimensions of approximately 16.75 inches wide, 16.86 inches deep, and 18.05 inches high. It has a 5-liter built-in water tank, two-place-setting capacity, multiple wash programs, hot-air drying, and extended air circulation.
It can operate in tank mode without a faucet connection, or you can use the included inlet hose when a direct water connection is more convenient.
AIRMSEN also currently lists a two-year manufacturer warranty for this model.
Why it works for small spaces: Its footprint is close to the HAVA and NOVETE models, while the manufacturer-listed noise level makes it interesting for open-plan studios and apartments.
What to consider: Capacity remains limited to two place settings, so this is designed more for frequent small loads than big family cleanup.
Best for: studios, open-plan apartments, and users who expect to run the dishwasher while spending time nearby.

4. NOVETE TDQR01 — Best for Larger Plates and More Dish Capacity
The NOVETE TDQR01 is worth considering if a typical two-place-setting countertop dishwasher feels too restrictive.
NOVETE lists the TDQR01 at approximately 16.9 x 16.8 x 18.1 inches, with a 5-liter built-in tank and four-place-setting capacity. The manufacturer says it can accommodate dishes up to 12 inches when loaded at an angle.
It offers five main wash cycles, including a heavier high-temperature mode, along with hot-air drying and automatic ventilation after washing. The system can work from its water tank or from a faucet connection.
The interesting part is that its exterior footprint remains similar to several two-place-setting machines in this guide while NOVETE lists more internal dish capacity.
Why it works for small spaces: It aims to fit more dishes without requiring a dramatically larger countertop footprint.
What to consider: Manufacturer capacity ratings do not tell the whole story. Large bowls, pans, mugs, and unusually shaped dishes can reduce the number of pieces that fit in a real load.
Best for: couples who generate more dishes, small households, or anyone worried that a two-place-setting model will feel too restrictive.

5. AIRMSEN ZMW-DUHA01 — Best for Shallow Counters and More Capacity
The AIRMSEN ZMW-DUHA01 takes a different approach to saving space.
Instead of trying to minimize width, it minimizes depth.
The dishwasher measures approximately 21.6 inches wide, 14.2 inches deep, and 19.6 inches high. AIRMSEN lists a 5.2-liter built-in tank and five-place-setting capacity. It also has a two-level rack, three spray arms, heated drying, extended air refresh, and a built-in water softener.
That 14.2-inch depth is the key reason to consider it.
A traditional compact dishwasher may be narrower, but its deeper body can consume most of a shallow countertop. This model is wider, yet leaves more usable counter area in front of the appliance.
AIRMSEN says the dishwasher can also fit plates up to 11.8 inches when the upper basket is removed.
Why it works for small spaces: It trades extra width for a noticeably shallower footprint and larger internal capacity.
What to consider: At 21.6 inches wide and 19.6 inches high, this is not the best choice for a very narrow counter or a tight space beneath low cabinets.
Best for: shallow countertops, households that need more dish capacity, and kitchens where width is available but counter depth is limited.

Do Countertop Dishwashers With Water Tanks Really Need No Plumbing?
For normal tank-mode operation, no permanent water supply connection is required.
You manually fill the built-in reservoir before starting the dishwasher.
But there is one important detail that people sometimes miss:
The dirty water still has to go somewhere.
These machines use a drain hose, which normally empties into your kitchen sink or another suitable container.
So “no hookup” does not mean the appliance is completely independent of water management. It means you do not need to install a permanent incoming water line.
For renters, that is a major advantage.
5-Liter Water Tank: Is That Enough?
Most of the compact models in this guide use approximately five liters, or a little over one gallon, for the water reservoir.
The tank is designed to provide the water required for a wash cycle on that specific machine.
You normally fill the tank before the cycle rather than continuously adding water while it runs.
For everyday apartment use, the more important question is not whether five liters sounds large. It is whether you are comfortable manually filling the machine whenever you wash dishes.
If you run several loads back to back every day, a faucet connection may become more convenient.
How Much Counter Space Do You Need?
Do not measure only the body of the dishwasher.
You should consider four things:
The space required by the machine itself, enough room above the unit to fill a top-mounted tank, space for the door to open, and a practical route for the drain hose to reach the sink.
Upper cabinets are especially important.
A dishwasher that technically fits beneath a cabinet may still be frustrating if you cannot comfortably pour water into the reservoir.
Measure your counter before ordering.
Countertop Dishwasher With Tank vs. Faucet-Only Model
A built-in tank is usually the better choice when you rent, have an unusual faucet, do not want to disconnect your faucet every time you wash dishes, or want the flexibility to place the machine away from the sink.
A faucet-only countertop dishwasher can make more sense if you run several loads in a row and do not mind connecting a hose.
Many of the models in this guide offer both options, which gives you flexibility if your kitchen setup changes later.
What Size Is Best for One or Two People?
For one person, a two-place-setting dishwasher may be enough if you run it regularly.
For two people, it depends on how much you cook.
If you prepare most meals at home, a four- or five-place-setting model may reduce how often you need to run the dishwasher.
If most of your dishes are plates, cups, bowls, and utensils, a smaller model can be perfectly practical.
If you regularly use pans, food-storage containers, large mugs, and mixing bowls, internal layout becomes much more important than the advertised place-setting number.
FAQ
Are countertop dishwashers good for apartments?
They can be especially useful in apartments without a built-in dishwasher because tank-equipped models require no permanent incoming water connection. You still need electricity and somewhere for the drain hose to empty.
Can I use a countertop dishwasher without connecting it to the faucet?
Yes, if the model includes a built-in water tank and supports tank mode. The models in this guide are designed to operate that way.
Where does the dirty water go?
Through a drain hose. Most people place the end of the hose in their kitchen sink while the dishwasher runs.
Will a countertop dishwasher fit under my cabinets?
Sometimes, but measure carefully. Several popular tank models are around 17 to 18 inches high, while larger-capacity designs can approach 20 inches. You also need enough room to fill the tank if the water inlet is located on top.
Is a countertop dishwasher large enough for pots and pans?
Small cookware may fit, but compact machines are mainly designed around plates, bowls, cups, utensils, and smaller kitchen items. A large frying pan can consume much of the available rack space.
Final Thoughts
For most renters and small apartments, the HAVA R01 offers a practical balance of compact dimensions, tank operation, and everyday capacity.
If manufacturer-listed noise is especially important, the AIRMSEN TDQR03 is worth a closer look.
The NOVETE TDQR01 makes more sense when you want additional dish capacity without a much larger external footprint, while the AIRMSEN ZMW-DUHA01 is the most interesting choice when your counter is shallow but wide enough for a larger machine.
And if high-temperature cleaning is high on your priority list, the COMFEE CDC17P0ABB deserves consideration.
The most important step before buying any of them is simple:
Measure your counter, measure the cabinet clearance above it, and make sure the drain hose can comfortably reach your sink.
A countertop dishwasher only saves time if it actually fits the way you use your kitchen.
