The Midea 18 Inch Built-in Dishwasher is the best 18 inch dishwasher for most compact kitchens because it combines 8 place settings, adjustable legs, and a stainless steel tub. For a black exterior, consider Honeywell, while Frigidaire is the option here with an ADA-compliant design.
An 18-inch dishwasher saves cabinet width compared with a standard-width built-in unit, but it still needs a correctly sized opening, plumbing, and door clearance. If permanent installation does not suit your kitchen, compare portable dishwasher options.

Use the stated dimensions as a starting point, then check the installation requirements for your kitchen.

How these 18-inch dishwashers differ
The main differences are finish, rack flexibility, installation details, and the dimensions you need to fit. We compared those specifications and features against the needs of kitchens with limited cabinet width.
The Midea and COMFEE' models share a stated 17.6-inch width and 8-place-setting capacity. Honeywell has a black glossy finish, while Frigidaire is ADA compliant and stands 35 inches tall.
EdgeStar adds a leak sensor and publishes a cutout width. SPT is designed for top-mount installation, so the mounting method matters when planning cabinet support.
Our score weighs specs and features against what you're shopping for. Scores reflect how well each model's documented features fit the needs of an 18-inch dishwasher buyer.

Midea 18 Inch Built-in Dishwasher: Best for flexible everyday loads
- 8 place settings
- 17.6 in wide
- Adjustable legs
- Stainless steel tub
A slim built-in model with adjustable legs, six wash programs, and three extra functions. The stainless steel tub and 8-place-setting capacity suit a compact kitchen with regular dish loads.
Pros
- Six wash programs
- Heated dry, Hi-Temp, and Sanitize functions
- Adjustable legs
Cons
- White exterior may not match every kitchen
- Check cutout dimensions before installation
The Midea 18 Inch Built-in Dishwasher is a strong fit when you want a slim cabinet with the stated capacity of 8 place settings. Its dimensions are 22.6 in deep, 17.6 in wide, and 32.4 in high, with adjustable legs to help fit the opening.
It has a stainless steel tub, six wash programs, and three functions: Heated Dry, Hi-Temp, and Sanitize. The digital control panel has an LED display, and the maker describes space for plates, pots, and pans up to 11 inches high.
The exterior color is white, so it may stand out in a kitchen with black or stainless appliances. Midea describes the model as under-counter installation, but you should check the opening, supply, drain, and electrical requirements before planning a replacement.
If you would rather avoid a built-in installation, read our HAVA R01 countertop dishwasher review.
Choose it for a compact built-in with flexible wash options and adjustable legs. If you need a black exterior or a panel-ready front, confirm those requirements with the brand before deciding.
COMFEE' 18 Inch Built-in Dishwasher: Best for an adjustable upper rack
- 8 place settings
- 17.6 in wide
- Adjustable upper rack
- Stainless steel tub
An 18-inch built-in dishwasher with an upper rack that adjusts up to 1.97 inches. That rack gives you more room to fit taller cookware while keeping the compact cabinet width.
Pros
- Adjustable upper rack
- Heated Dry, Hi-Temp, and Sanitize functions
- Six wash cycles
Cons
- Stainless steel exterior may not suit a black appliance set
- Confirm cabinet and cutout fit
COMFEE' suits kitchens where the upper rack needs to move to make space for cookware. It adjusts by up to 1.97 inches, and the lower rack is described as accommodating dishware up to 13.78 inches high.
The model has 8 place settings and measures 22.6 in deep, 17.6 in wide, and 32.4 in high. Its stainless steel tub and six wash cycles make it similar in core size to the Midea, with rack adjustment as a useful distinction.
Heated Dry, Hi-Temp, and Sanitize functions are included. COMFEE' describes the model as a built-in dishwasher, and its exterior is stainless steel.
Choose it if rack height flexibility matters for your cookware. Check the model's installation instructions and cabinet opening before arranging installation.
Honeywell 18 Inch Dishwasher with 8 Place: Best for a black built-in finish
- Black glossy finish
- 18 in wide
- Stainless steel tub
- ADA-compliant
Honeywell offers a black glossy finish in a built-in 18-inch width. Its stated capacity details conflict, so confirm the usable rack layout and capacity before choosing it for a larger household.
Pros
- Black glossy exterior
- Stainless steel tub
- Six washing programs and delay start
Cons
- Capacity information is inconsistent
- Width is 18 in, slightly wider than some slimline options
Honeywell is the clearest choice in this group when an 18-inch black built-in dishwasher is the priority. It has a glossy black finish, a stainless steel tub, and dimensions of 22.6 in deep, 18 in wide, and 32.4 in high.
Capacity details conflict: the title says 8 place settings, while the feature text says 14. Treat capacity as something to confirm with Honeywell before buying, especially if you regularly wash large loads.
The model is described as ADA compliant and under-counter installation. It has six washing programs and a delay start of up to 24 hours, according to the product information.
Choose Honeywell for the black finish if the installation and confirmed capacity fit your needs. Its 18-inch width is slightly larger than the 17.6-inch width stated for Midea and COMFEE', so compare the actual opening carefully.
EdgeStar BIDW1802SS 18 Inch Wide 8 Place: Best for a leak shutoff feature
- 8 place settings
- 17.6 in wide
- Leakage sensor
- Stainless steel finish
This stainless steel built-in model fits 8 place settings and includes a leakage sensor that shuts off water flow when a leak is detected. Its stated cutout width is 17.75 inches.
Pros
- Leakage sensor shuts off water flow if it detects a leak
- Six wash cycles
- 52 dB operation
Cons
- Door-open depth needs planning
- Confirm the cutout and mounting details
EdgeStar fits buyers who want a stainless steel finish and a documented leak response feature. Its sensor automatically shuts off water flow when it detects a leak, and the unit accommodates up to 8 place settings.
Its stated dimensions are 22.4 in deep, 17.6 in wide, and 32.5 in high. EdgeStar also gives a cutout size of 32.5 in high by 17.75 in wide by 23 in deep, which helps when checking the cabinet opening.
The six wash cycles include Heavy, Normal, ECO, Glass, Rapid, and Rinse. The model also has Sanitize, Hi Temp, and Heated Dry options, plus a stated operating noise of 52 dB.
Choose it when the leak shutoff feature and published cutout dimensions answer your main concerns. Confirm mounting details and open-door clearance before installation.
FRIGIDAIRE 18 in. ADA Compact Front Control: Best for ADA-compliant installation
- ADA compliant
- 8 place settings
- Stainless steel finish
- Dual spray arms
Frigidaire combines an ADA-compliant design with capacity for up to 8 place settings. Its stated height is 35 inches, so check that measurement carefully against the available opening.
Pros
- ADA compliant
- NSF-certified Sanitize cycle
- Heated drying system
Cons
- Taller than several other options here
- Verify opening height before purchase
Frigidaire is the ADA-compliant option in this roundup and fits up to 8 place settings. Its stainless steel exterior and front controls suit a visible built-in installation where you want a familiar appliance finish.
The stated dimensions are 18 in deep, 22.5 in wide, and 35 in high. Those dimensions are listed in a different order from the other models, and the width is broader than the 17.6-inch slimline models, so verify the full installation drawing.
Features include dual spray arms, a heated drying system, and an NSF-certified Sanitize cycle. The extra height may work in some openings, but it makes careful measurement especially important.
Choose Frigidaire if ADA compliance is a priority and the opening can accommodate the stated height and width. Ask the installer to confirm the fit before ordering or removing an existing dishwasher.
SPT SD-9254SSB 18″ Wide Built-In Stainless Steel: Best for top-mount installation
- 8 place settings
- Stainless steel tub
- Top-mount installation
- Heated drying
SPT is a compact built-in dishwasher with six wash programs and a heating function during drying. It is designed for top-mount installation and includes top-mounting brackets.
Pros
- Heated drying function
- Six wash programs
- Drain tube and top-mounting brackets included
Cons
- Side-mounting brackets are not included
- Confirm the mounting method suits your cabinets
SPT is suited to a kitchen where top-mount installation matches the cabinet construction. It includes top-mounting brackets, while side-mounting brackets are not included, so the support method should be settled before purchase.
The dishwasher has a stainless steel tub and a stated capacity of 8 place settings. It measures 22.6 in deep, 17.6 in wide, and 32.4 in high, with six programs including Normal, Heavy, Energy, Glass, Quick, and Rinse.
SPT includes a heating function during drying, a drain tube, and a time-delay feature. Its described operating noise is 52 dB.
Choose this model when the top-mount requirement fits your cabinets and you want heated drying. If your installation depends on side brackets, check the mounting plan first.
How do you measure for an apartment-size 18-inch dishwasher?
Measure the cabinet opening at the narrowest points, then compare its width, height, and depth with the exact model dimensions. Include space for hoses, connections, and the open door in your planning.
The “18-inch” label is a size class, not a guarantee that every model has the same width. Midea and COMFEE' state 17.6 inches wide, while Honeywell states 18 inches, so a tight opening deserves an exact check.
Measure from finished floor to the underside of the counter, and account for any flooring that may change the final height. Check depth from the cabinet face to the back wall, including valves, outlets, and drain connections.
The opening also needs a suitable mounting surface and access to water, drain, and power. For a full measuring checklist, use our apartment-size dishwasher dimensions guide.
Is a black 18-inch built-in dishwasher the right finish?
Honeywell is the black option among these picks, with a glossy black exterior and stainless steel tub. The other listed finishes are white, stainless steel, or gray, so choose based on the visible door and nearby appliances.
Searches for an 18 inch built in dishwasher black often mean one of two things: a black finished appliance or a dishwasher hidden behind a cabinet panel. Those are different requirements.
A black appliance has a finished door designed to remain visible. A panel-ready dishwasher needs a design that accepts a cabinet front, and panel compatibility is not confirmed for the models in this roundup.
For a black stainless exterior, compare black stainless steel dishwashers.
If you need a black finish, confirm the precise color and handle appearance with the brand. If you need a hidden panel, ask about panel dimensions and installation hardware before selecting a dishwasher.
Can an 18-inch dishwasher fit under a sink?
It may fit under a counter near a sink, but the sink bowl and plumbing can take up the space the appliance needs. Measure the usable cabinet opening after accounting for the basin, trap, supply lines, and drain.
If the built-in opening is too tight, compare compact countertop dishwashers for another placement option.
Midea and COMFEE' are described as under-sink or under-counter models, but that wording does not guarantee they fit beneath every sink. Compare the full appliance height and depth with your cabinet layout and installation instructions.
Plan hose routing and shutoff access before installation. A tight or awkward cavity can make servicing harder even if the appliance body appears to fit.
If the sink cabinet is your only possible location, review our guide to choosing a small dishwasher for under a sink before you settle on a model.
Should you choose built-in, countertop, or panel-ready?
Choose a built-in 18-inch dishwasher if you have a suitable cabinet opening and permanent water, drain, and power connections. A countertop model is a different format and may suit a renter who cannot modify cabinetry.
The six products here are built-in models. Their information does not confirm that they accept cabinet panels, so don't assume a standard front can be covered.
If you are still comparing formats, our small dishwasher apartment guide covers compact alternatives. For countertop options, see how a mini countertop dishwasher works.
Which finish and tub details should you compare?
Compare the visible exterior separately from the tub material, since the two describe different parts of the dishwasher. The Midea, COMFEE', and Honeywell options specify stainless steel tubs, while the finishes vary by model.
Midea is white, COMFEE' and EdgeStar are stainless steel, Honeywell is glossy black, and SPT is gray with a stainless steel finish description. Frigidaire is stainless steel and has front controls.
If you want a coordinated metal finish, our best stainless steel dishwashers guide can help you compare more options. Check whether the control panel, handle, and door finish all match your kitchen before ordering.
Which 18-inch dishwasher should you choose?
Choose Midea for the most balanced set of 8-place-setting capacity, adjustable legs, and wash options. Pick COMFEE' if its adjustable upper rack solves a cookware-fit issue, Honeywell if you want a black finish, and Frigidaire if ADA compliance is central.
For an opening that needs exact sizing, compare the published dimensions and installation details before purchase. The EdgeStar is useful when its leak sensor and stated cutout dimensions match your priorities, while SPT fits a top-mount installation plan.
If you want the broadest compact-appliance comparison, start with our best dishwashers for small spaces. For another finish-focused comparison, browse best stainless steel dishwashers.
The decision rule is simple: choose by opening and installation first, then finish and rack layout. That order helps avoid a model that looks right but cannot fit your cabinet or mounting setup.

Frequently asked questions
Is an 18-inch dishwasher wide enough for an apartment?
An 18-inch built-in dishwasher can suit an apartment kitchen when the cabinet opening, water connections, and drain match the model's requirements. Several picks here accommodate 8 place settings.
Measure the opening and door swing, then compare them with the appliance dimensions and installation instructions before buying.
What is the difference between an 18-inch and countertop dishwasher?
An 18-inch model is a built-in appliance that needs a cabinet opening and plumbing connection. A countertop dishwasher sits on a counter and usually connects to a faucet or uses a water reservoir.
If you are considering a portable format, see how a mini countertop dishwasher works.
Can an 18-inch dishwasher fit under a sink?
Some 18-inch models are described for under-counter or under-sink placement, but the sink basin, drain, supply lines, and cabinet opening can limit usable space. Measure the full cavity and check the installation instructions for clearances.
Our small dishwasher under sink guide covers those fit checks.
Do 18-inch dishwashers come in black?
Yes. The Honeywell option here has a black glossy finish and an 18-inch stated width.
Check the exact exterior color and the door dimensions before ordering, especially if you need it to match nearby appliances or cabinets.
Can I add a cabinet panel to an 18-inch dishwasher?
Panel compatibility depends on the specific dishwasher design. The product details here do not confirm a panel-ready front for these six models, so don't assume a cabinet panel can be attached.
Check with the brand or installer for panel dimensions, mounting hardware, and door-weight limits before choosing a model for a concealed look.
