Check Price on Amazon

The quietest 18-inch wash you can park under a small counter without hearing it run.

This COMFEE’ runs at 52dB — about the level of a quiet library — which makes it a standout for open-plan apartments or kitchens next to living rooms. The stainless tub helps it shrug off the wear of daily washes, and the adjustable top rack can raise up to 1.97 inches to clear deep pots.

You get six wash cycles plus Heated Dry, Hi-Temp, and Sanitize functions. The Hi-Temp cycle pushes water up to 136°F (58°C), which is why owners trust it for baby bottles and heavily soiled cookware. The Heated Dry leaves dishes cabinet-ready on all cycles except Rapid and Self-Clean. Its lower rack even fits oversized plates up to 13.78 inches tall.

Buyers report the dishes come out “spotless” and the unit feels sturdier than its size suggests. The one catch: it does not ship with a power cord, so you will buy that separately during installation.

The name that keeps coming up when owners compare it to full-size machines they have owned.

This Midea is the most-reviewed compact on the list, and the crowd verdict is clear: it beats expectations. Owners with past name-brand dishwashers call it “by far the best” and highlight how its 17.6″W x 32.4″H frame still swallows big pots, pans, bakeware, and utensils up to 11 inches tall. A digital control panel with an LED display keeps the front clean.

It runs six programs — Heavy, Normal, ECO, Delicate, Quick, and Rinse — plus Heated Dry, Hi-Temp, and Sanitize functions. The Hygiene cycle holds water at 136°F (58°C) max for the heaviest soil and for cleaning baby bottles and children’s dinner sets. The Heated Dry works on all cycles except Rapid and Self-Clean, so plastic and glass come out ready to put away.

Owners mention it is “completely silent” and inexpensive to run, with one couple running it every other day for just the two of them. The honest trade-off: delivery quality varies, and a few owners waited weeks on a working unit or on customer service. If you want proven cleaning from a familiar appliance brand, this is the one to grab.

A stainless-steel look that lets a compact built-in hide in plain sight among full-size appliances.

If your kitchen is all stainless, this Honeywell version matches where the white model would stand out. Beyond the finish, it steps up the materials inside — the dishwasher basket and rack are both stainless steel rather than plastic. The tub is stainless too, which helps with efficiency and drying.

It carries six washing programs — heavy, normal, eco, glass, rapid, and rinse — covering everything from delicate stemware to crusted casseroles. The up-to-24-hour delay start and a removable cutlery basket round out the package. Owners note the Sanitize function is great for baby items and that the unit cleans well for its 18-inch size.

The mixed area is reliability: some customers note E4 error codes on first use, while others have run it reliably for six months. If you like the look and are prepared to work through an occasional error reset, it delivers solid cleaning. If you want zero-touch reliability, the higher-reviewed options above are a safer wager.

The 18-inch built-in with a leakage sensor that watches for water when you are not looking.

EdgeStar adds a genuine peace-of-mind feature: an automatic leakage sensor that shuts off the water flow when it detects a leak, protecting your floors and cabinets. That is a meaningful layer of defense for a compact unit tucked under a sink. It runs at a quiet 52dB, and at just 17.75 inches wide, it easily replaces an old trash compactor slot.

Inside, the stainless basket and rack hold eight place settings with a silverware basket and cup tray. You get six wash cycles — Heavy, Normal, ECO, Glass, Rapid, and Rinse — plus Sanitize, Hi Temp, and Heated Dry options. The unit measures 32.5″H x 17.6″W x 22.4″D and weighs 52.9 pounds, so two people can manage the install.

Cleaning performance is the headline across hundreds of owners — it surpasses expectations and handles heavy loads with the heavy-plus-sanitize combo. The trade-offs are practical: no power cord is included, cycle times run long (heavy takes 2h40m), and settings do not save between cycles. If you want leak protection with strong cleaning, this is the quiet pick.

A wheeled washer that connects to your faucet, so renters can ditch the hand-washing routine.

This SPT portable is for kitchens with no built-in slot. It rolls up to the sink, connects with the included faucet adapter, and washes a full 8 place settings free of any cabinet work. A full console control panel with six programs — Heavy, Normal, Eco, Glass, 90 Min, and Rapid — handles everything from a quick rinse to a heavy load.

The stainless steel interior resists stains and odors, while the adjustable upper rack makes room for larger plates and pots. A rinse aid warning indicator reminds you when to refill, and a time delay feature lets you program a later start from 1 to 24 hours. At 114 pounds, it is heavy enough that you will want a second person to help wheel it upstairs.

Owners say it handles a family of five in one load when packed well, and dishes come out clean and dry. The recurring note is capacity: the 8 place setting claim feels optimistic, and odd-shaped items are tough to fit. It is CSA-US certified, which matters for North American electrical and safety standards.

The stainless portable twin of the white model, built to roll and match a modern kitchen.

This SPT shares the portable DNA of the white version above but wraps it in a stainless finish for kitchens that already run on metal appliances. It is freestanding, so it hooks to your faucet and rolls out of the way when not in use. An LED display and full panel controls keep the front easy to read.

It holds 8 place settings across a stainless basket and rack, with a 5-gallon capacity tank. The Energy Star label means it sips power — rated at 237 kilowatt hours per year. Reviewers point out it cleans “as well as Samsung” and describe it as extremely quiet, with a 60-minute wash leaving dishes spotless and dry.

The trade-offs surface around installation: the hoses are external and not retractable, and some owners found leaks when not laid flat during setup. Drying is weaker on plastic without airflow, so many prop the door open after a cycle. If you want a stainless portable that matches your appliances, this is the one; just budget time for the hose setup.
