Compact built-in dishwashers measure about 18 inches wide, 24 inches deep, and 35 inches high, which makes an 18-inch built-in the safest default for a small kitchen. It still needs door clearance, a level floor, and water, drain, and electrical access nearby. If you rent, or your layout has no cabinet opening, a countertop model is the practical alternative, and every product below falls into that group.
Based on the specifications and listings, the five models here are portable countertop units. They use a built-in 5-liter tank or a faucet hose, so none needs a permanent plumbing connection.
Our Winner: EUHOMY 6 Programs Countertop Dishwasher Portable, 40dB, 360° Coverage
This model combines a 4.5/5 rating, a listed 40 dB noise level, and a tank-or-faucet water supply. It measures 16.85 inches deep, 16.73 inches wide, and 18.03 inches high, so it suits most counters. Based on the specifications, it is the most balanced option for apartments and tight layouts.
How We Compared These Models
We compared the models on footprint and height, water supply flexibility, noise level, and cycle options. Footprint and height decide whether the unit fits under a wall cabinet. Noise matters in open-plan apartments. These points come from the listed specifications and the features each seller publishes.

Built-in vs Compact vs Portable Dishwashers
Your kitchen layout decides the type. This table gives a simple rule for apartments and tiny kitchens.
| Type | Fit | Installation Needs | Best Use Case |
|---|---|---|---|
| 18-inch built-in | Cabinet opening at least 18 in wide, 23 in deep, 32.5 in high | Water supply, drain, grounded outlet, door clearance | Owners with a spare cabinet slot |
| Portable countertop | About 17 in wide and 18 in high, needs counter space | Outlet, tank filling or faucet hose, drain hose | Renters, dorms, RVs |
| Slim smart built-in | Same opening as a compact built-in | Full hookups plus Wi-Fi | Owners who want app control |
Decision rule: if you have a cabinet slot and permission to modify plumbing, choose an 18-inch built-in. If not, choose a countertop unit.
How Do I Fit a Dishwasher in a Small Kitchen?
Start with measurements. The IKEA VILLKORLIG installation instructions call for an enclosure at least 18 inches wide, 23 inches deep, and 32.5 inches high. Whirlpool also publishes a guide on how to measure for standard dishwasher sizes.
Measurement Checklist
- Opening width at the top, middle, and bottom.
- Opening depth from the wall to the cabinet front.
- Height from floor to the underside of the countertop.
- Floor level, since the unit needs to sit flat.
- Open floor space in front of the unit.
- Distance to the sink, the outlet, and the shutoff valve.
Worked Example
Suppose a hypothetical opening measures 18.25 inches wide, 23.5 inches deep, and 34 inches high. Against the 18 by 23 by 32.5 inch minimums, it passes on all three. The aisle in front must also allow door swing. Some installations need about 25 5/8 inches of front clearance, so a 30-inch aisle works and a 24-inch aisle does not.
Where Can a Dishwasher Go, and Where Can It Not?
Can you put a dishwasher anywhere in a kitchen? No. Installation typically requires proximity to the sink and specific plumbing and electrical conditions. Can you add a dishwasher to any kitchen? Only if it has a suitable opening or counter, plus access to utilities.
- Sink distance: some manufacturers require installation within 9.8 feet of the sink. Other guidance says no more than 10 feet from the sink or primary drain.
- Drain hose: some guides say it should not exceed 10 feet.
- Electrical: a dedicated 110/120-volt grounded outlet on a 15 or 20-amp breaker may be required within 5 feet of the installation location.
- Cooktops: one manufacturer says not to install a dishwasher under a cooktop range. Check the Bosch installation instructions and your own model’s manual.
The ideal placement is beside the sink, with the outlet and shutoff valve within reach. A dishwasher next to a cooktop is a separate question, so confirm clearances in the manual.

Smart Features Worth Paying For
Is it best smart dishwasher for small kitchens? None of these five models lists app control. The features that matter most in compact units are quiet operation, delay start, a child lock, and a quick cycle. Wi-Fi mainly appears on full-size built-ins.
Common Mistakes When Planning a Small-Kitchen Install
- Measuring only the opening width and skipping door swing.
- Forgetting the height of the wall cabinet above a countertop model.
- Placing the unit far from the sink or a grounded outlet.
- Planning a built-in under a cooktop range.
Frequently Asked Questions
How do I fit a dishwasher in a small kitchen?
Measure the opening or counter space, then compare it with the model’s listed dimensions. For built-ins, plan for at least 18 by 23 by 32.5 inches. For countertop units, check the height against the wall cabinet.
How do I place a dishwasher in a small kitchen?
Put it beside the sink so water and drain access stay short. Keep an outlet within reach and leave room for the door to open.
Can you add a dishwasher to any kitchen?
Not always. A built-in needs a suitable cabinet opening plus plumbing and electrical access. A countertop model is the workaround when those are missing.
Can you put a dishwasher anywhere in a kitchen?
No. Guidelines call for sink proximity, with limits of about 9.8 to 10 feet, and a nearby outlet. Some manufacturers also forbid placement under a cooktop range.
What size dishwasher is best for a small kitchen?
An 18-inch built-in is the safest default. A portable countertop unit of about 17 inches wide suits renters.
Conclusion
If you have a cabinet slot and the right hookups, an 18-inch built-in is the standard answer. For everyone else, the EUHOMY B0CLVBQS15 is the best overall pick among these five, thanks to its 4.5/5 rating, 40 dB noise level, and flexible water supply. Choose the Hermitlux for delay start, and the COMFEE’ if the lowest USD price matters most. Measure first, and confirm door clearance before ordering.
