Before you buy a built-in dishwasher, you need to know if it will fit the gap under your counter and clean quietly. That gap is either a standard 24 inches wide or a tighter 18 inches, and guessing wrong means a costly return. You also face trade-offs in washing power, noise (measured in decibels), capacity (how many place settings fit), and whether the unit includes the parts you need for installation.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The best built-in dishwasher for your kitchen pairs a quiet motor with enough cycles for daily messes and a footprint that fits your cabinet opening.
Our Picks at a Glance
How To Choose The Best Built Dishwasher
Before you compare wash cycles or noise levels, measure the opening under your countertop. A standard 24-inch dishwasher fits most American kitchens, but many apartments, condos, and older homes have an 18-inch gap — often where a trash compactor used to live. Choose the wrong width and nothing else on the spec sheet matters.
Match the Width First, Then the Wash Power
An 18-inch model typically holds 8 place settings, while a 24-inch unit jumps to 12 or more. That gap is huge for a household of four or more — 12 place settings versus 8 is a 50% capacity difference, meaning fewer daily loads and more room for pots and baking sheets. If you feed more than two people regularly, the wider footprint usually wins on convenience alone.
Decibels, Deciphered
Noise is measured in decibels (dB), and the number matters most in open-concept homes where the kitchen bleeds into the living room. A 52 dB wash is quiet enough for most people to talk over, while a 47 dB model is the kind of machine you forget is running until you open the door. A few decibels can mean the difference between a dishwasher you forget is running and one that interrupts conversation.
Tub Material and Drying Are the Real Dividers
A stainless steel tub holds heat better and resists odors compared to plastic, which is why serious buyers check the inner material before the brand name. Drying method matters just as much — a heated dry cycle that forces hot water down the drain leaves plastic cups and containers ready to put away, versus a model that leaves everything damp. Check whether the machine includes a heated dry option or a rinse aid dispenser, since both quietly determine whether you are towel-drying after every load.

In‑Depth Reviews
1. EdgeStar 18 Inch Wide Built-In Dishwasher
Our pick — over 4★ from 800+ verified ratings; the strongest balance of quality and price.
The 18-inch cleaning champion that turns a trash-compactor gap into a washing powerhouse.
Cleaning performance is the standout feature, with 122 owners praising it as the top reason for their satisfaction. The six wash cycles, which run from Heavy down to Rinse, give you a dedicated Glass cycle and a Rapid option for when you need plates in a hurry. That is one more cycle than the Honeywell 18-inch below, and buyers report the Sanitize plus Heavy combo powers through even the crustiest loads.
At just 17.75 inches wide and 52.9 pounds, this unit is designed to slide into a slot left by an older trash compactor — a smart retrofit for older kitchens. The 52 dB noise rating keeps conversation flowing while it runs, and the leakage sensor automatically cuts the water flow the moment it detects a drip, protecting your floors from damage. Owners consistently note it holds more than they expected, and several report being very satisfied after five or more months of steady use.
Owners say this 18-inch model cleans dishes better than their old full-size Kenmore, making it the enthusiast pick in this size. Installation is straightforward if you are handy, but the unit does not include a power cord, and a few owners mention a recurring E4 overflow error (a code indicating excess water) that needed a long reset. The digital push-button controls do not save your settings between loads, so you will reselect your cycle each time.
What wins people over
- Cleaning power is the #1 praise point — 122 owners highlight it
- Genuinely quiet at 52 dB with a leakage sensor for floor protection
- Slim 17.75-inch width fits trash-compactor slots perfectly
Worth knowing before you buy
- No power cord included — budget for that part
- Settings do not save between loads
- A minority report an E4 overflow error needing long resets
Reach for this if: you want the best-cleaning 18-inch built-in and can handle a straightforward hookup.
Think twice if: you expect plug-and-play installation with zero extra parts.
2. Midea 18 Inch Built-in Dishwasher
The 18-inch built-in that feels more premium than its price suggests.
Quality is the most-praised aspect, mentioned by 112 owners. That enthusiasm usually appears in the same sentence as “silent” or “spotless,” which tells you the two things that matter most here. The stainless steel tub gives it a classy interior that resists odors while the Heated Dry function (available on every program except Rapid and Self-Clean) means you rarely reach for a towel.
Against the EdgeStar above, this one leans quieter and more refined in daily use — owners describe it as completely silent and even prefer it to a Bosch at double the price. The catch: some units arrive with defects, and when they do, customer service has been described as unprofessional with delayed repairs. An occasional unit shows up with a leak from the sump pump housing, so do a quick check for the E4 code during your first run before you commit to the install.
Why owners stay happy
- Quality is the #1 mention — 112 owners praise it
- Heated Dry delivers cabinet-ready dishes, no towel needed
- Fits plates up to 11 inches tall in a slim 17.6-inch body
Fit-note honesty
- Use only dishwasher-specific detergent — liquid dish soap causes problems
- An occasional unit arrives with a sump leak
- Warranty support gets mixed reviews when defects appear
Grab it if: you want a quiet, quality-feeling 18-inch unit that dries dishes completely.
Look elsewhere if: you need bulletproof post-purchase support for a big appliance.
3. Sharp SDW6726MS 24-inch Stainless Steel Dishwasher
The whisper-quiet 24-incher with a third rack that you genuinely forget is running.
This is the quietest machine in the lineup, and the noise level is the single most-praised feature among owners. At just 47 dB — the “Library Quiet” rating — the wash is so unobtrusive that family members watching TV a room away have asked whether the dishwasher is even on. For anyone in an open-concept home, that silence is worth real money.
Beyond the hush, the layout is built for flexibility. A third rack up top dedicates space for flatware and serving utensils, while the Power Wash sprayer targets heavily soiled dishes with extra scrubbing force. The built-in soil sensors automatically adjust the wash cycle, so the machine figures out how dirty your load is and responds. Twelve place settings and five wash cycles (plus four options) cover a standard household comfortably.
Owners describe the quality as unsurpassed and often forget the machine is running mid-cycle. A few buyers found the drain and water hookups awkward, so budget for a professional installer if you are not handy. The fingerprint-resistant stainless finish keeps the front looking clean between wipes.
The case for going Sharp
- 47 dB is the quietest rating here — owners forget it is running
- Third rack plus Power Wash sprayer handle bulky and delicate loads
- Soil sensors auto-adjust the cycle to your mess
The case for caution
- Water and drain hookups drew sharp criticism from some owners
- Five wash cycles is fewer than the budget Honeywell offers
Choose it if: silence and a flexible third rack matter more than cycle count.
skip it if: you plan to self-install and want forgiving hookups.
4. Kenmore 24″ Built-In Dishwasher
The 24-inch family hauler with a rack that lifts, lowers, or disappears entirely.
Adjustability is what owners talk about most with this Kenmore, and it is easy to see why. The MoreSpace Adjustable Upper Rack raises, lowers, or removes completely, so a single machine adapts between a load of tall stemware and a sink full of bulky pots. The removable utensil basket splits apart for flexible loading, and the racks themselves are stainless steel — a step up from the plastic racks on most budget units.
Capacity is the headline number: 14 place settings is the most in this entire lineup, beating the 12-setting machines by a meaningful margin. The 3-stage UltraWash Filter catches particles as small as a grain of fine sand and drains them away so they never redeposit on your dishes, and the filter pops out easily for monthly cleaning. SmartWash sensor tech reads the soil level and adjusts water temperature, pressure, and cycle time to match, while the Express Cycle gets a full load done in just 50 minutes.
Owners appreciate the sleek design, quiet operation, and the easy-to-clean food catcher, with many reporting dishes come out sparkling. The honest mixed note: drying performance is inconsistent — some report dishes are fully dry while others say drying is “not so good,” so you may want to use the SmartDry Plus option. A few units also arrive with visible damage, so inspect carefully before you commit to the installation.
The flexibility payoff
- Rack adjustability is the top praise — 7 owners single it out
- 14 place settings leads every machine on this list
- UltraWash Filter catches sand-sized particles and cleans easily
What to watch
- Drying draws mixed reviews — keep SmartDry Plus in mind
- A few units ship with visible damage
- Reliability reports are split, with some random shut-offs reported
Pick it for: a growing family that needs max capacity and rack flexibility.
Be careful if: you need guaranteed dry plastic every single cycle.
5. Honeywell 24 Inch Dishwasher with 12 Place Settings
The most wash cycles in the lineup at a price that surprises you.
Seven wash cycles with three modes give you the most program variety in this lineup, beating the EdgeStar’s six. You get a Quick Wash plus a delay start that stretches up to 24 hours, so you can load at night and have it run during your off-peak hours. The 24.5-inch width fits a standard American kitchen opening with room to spare.
Owners are surprised by how quiet this machine runs. Buyers describe it as a quiet workhorse that was “not rated to be as quiet as it is,” which is a rare compliment for a budget machine. The stainless steel base with plastic sides keeps the cost down while the Energy Star rating holds electricity use to 240 kilowatt hours per year — a figure worth checking if you run it daily. Cleaning and drying get positive marks when paired with proper detergent and rinse aid.
The honest trade-off: quality is a coin flip. While some customers note no leaks and a beautiful finish that arrived next-day, others hit an error code 4 within minutes of first use along with water leaking from the bottom. A few also reported missing installation parts. This is the machine to buy if you want maximum cycle flexibility for the lowest spend — just plan to test it thoroughly on day one while returns are easy.
The budget math
- 7 wash cycles beats every other pick on this list
- Owners call it quieter than its rating suggests
- 12 place settings with a large removable cutlery basket
Where it gets dicey
- Some units leak from the bottom with an error code 4
- Quality feedback is genuinely mixed — inspect on arrival
- Missing installation parts reported by a few buyers
Buy it for: maximum cycle choice at the lowest entry point.
Test it hard if: you purchase, since a leak on day one means an early return.
6. Sharp SDW6504MS Stainless Steel Dishwasher
The 24-inch unit that rearranges itself to fit your tallest pots.
The defining trick here is the upper rack’s 2-inch height adjustment, which lets you drop the rack down to clear a stack of tall dinner plates or lift it to make room for a roasting pan below. Fold-down tines add another layer of flexibility, so you can lay flat an odd-shaped serving dish without sacrificing a whole column of space. The pocket handle keeps the front flush and modern.
At 52 dBA, this Sharp sits at the same noise level as the EdgeStar but in a full 24-inch body with a 12-place-setting capacity. The hybrid construction pairs a stainless steel interior with a heavy-duty plastic floor — a design choice that trims weight and cost. The Half Load Option is the quiet hero here for solo cooks, cutting water and energy use when you only have a few plates to wash.
Buyers who installed it correctly say it runs quietly and cleans well, with installation taking about two hours once they gathered parts from a local plumbing store. However, cleaning performance is the most debated topic: some say dishes come out great, while others report dishes “do not come out clean at all.” The sanitize cycle adds confidence, but if spotless results are non-negotiable, compare this to the EdgeStar’s more consistent record.
The smart-load edge
- 2-inch rack adjustment clears tall cookware easily
- Half Load Option saves water and energy on small loads
- 12 place settings with fold-down tines for odd shapes
The honest divide
- Cleaning performance draws sharply mixed owner reports
- No power cord included — plan a plumbing store run
- Touch buttons are sensitive to accidental brushes
Choose it if: your loading puzzle is tall pots and awkward cookware shapes.
Reconsider if: you demand flawless cleaning from the start with zero fiddling.
7. COMFEE’ 18 Inch Built-in Dishwasher
The 18-inch machine that stuffs full-size features into a narrow footprint.
Owners praise the thoughtful design, evident in details like the adjustable upper rack. The upper rack adjusts up to 1.97 inches to clear deep pots, while the lower rack swallows extra-large plates up to 13.78 inches tall — a figure that rivals what some 24-inch machines manage. The stainless steel tub resists odors and holds heat, and the whole unit weighs 54.7 pounds, making it manageable for a two-person install.
The six wash cycles mirror the Midea above — Heavy, Normal, Eco, Delicate, Quick, and Rinse — plus Heated Dry, Hi-Temp, and Sanitize functions. The heated dry delivers a cabinet-ready finish on every cycle except Rapid and Self-Clean, and the Hygiene cycle runs water up to 136°F (58°C), suited for baby bottles and children’s dinnerware. The 52 dB noise rating holds up in practice, with owners describing it as noticeably quieter than expected for a budget built-in.
The sharpest edge here is the NSF sanitization certification, which confirms the sanitize cycle meets real public-health standards — a meaningful checkmark for families with young kids. The main gotcha: it does not include a power cord, so budget for that part before your installer arrives. A few owners note heated dry leaves minor moisture on plastic items, which is common across most machines but worth knowing.
The compact overachiever
- Lower rack holds plates up to 13.78 inches tall
- NSF-certified sanitize cycle for baby bottles
- Stainless tub stays odor-resistant and durable
Plan around this
- Power cord sold separately
- Heated dry leaves minor dampness on plastics
- 18-inch width — not a standard 24-inch fit
Ideal for: tight kitchens that still want NSF sanitization and adjustable racks.
Not for: anyone who expects a plug-in installation with zero extra purchases.
8. SPT SD-9254SSB 18″ Wide Built-In Dishwasher
The 18-inch value pick that skips the pre-scrub ritual entirely.
Cleaning performance and quality both come up positive among owners, and the recurring line is that you can skip the pre-washing. Dishes go in with stuck-on food and come out clean, even on the quick cycle — which one owner called the best cleaning dishwasher they have ever had. That is high praise for a budget-tier machine, and it comes from the six wash programs that include Normal, Heavy, Energy, Glass, Quick, and Rinse.
The stainless interior and exterior keep things looking sharp in a galley kitchen, and the ENERGY STAR rating holds energy use to 234 kilowatt hours per year — a touch more efficient than the Honeywell 24-inch above. It holds 8 place settings in a 17.6-inch-wide body, and the heating function during the drying cycle handles the towel-free finish. Owners who leveled it properly report no door leaks even after months of use.
The catch is preparation. Owner reports repeatedly mention that you must read the install instructions carefully — some units arrive missing a key part, and the power cord is not included, which means a plumber or electrician trip for many buyers. One owner shipped it to Costa Rica and it worked immediately after minor transit damage, which speaks to the machine’s resilience. Fits small spaces and holds more than expected, but budget your time for the hookup.
Why it earns its keep
- Owners love that it cleans without pre-scrubbing
- Stainless inside and out at a budget price
- Efficient at 234 kwh per year with heated drying
The prep work
- Missing key parts reported — read instructions carefully
- No power cord included
- Long cycles if you feed it cold water
Choose it for: sparkling dishes on a budget in a narrow 18-inch space.
Prepare if: you buy — the install is DIY-friendly but parts-hungry.
9. Honeywell 18 Inch Dishwasher with 8 Place Settings
The quiet 18-inch workhorse that couples rave about for daily two-person loads.
Owners describe this as the perfect size for a two-person household, with the noise level being the thing people praise most — 11 owners highlight how quiet it runs. Sized at 18 inches wide and 32.4 inches tall with six wash programs (pots & pans, normal, china, quick, rinse only, and energy saver), it slides into a compact kitchen opening with 8 place settings of room inside. The 24-hour delay start is a genuinely useful touch for couples who want dishes done before they wake up.
Daily users report running the quick wash setting for two people and getting a great clean from a quiet, sturdy machine. The stainless steel tub is the durability upgrade here compared to plastic-lined budget rivals, and the ENERGY STAR rating keeps the operating cost low. Multiple owners describe it as incredible value for the money, with dishes coming out dry — superior to other dishwashers they have owned.
The trade-off appears specifically around error codes. Some owners hit a recurring error on first use that an installer could only temporarily fix, and customer service was transferred to another company that was unresponsive until 9 AM. These reports are the minority — most owners are delighted — but they cluster around the electronics, so run a test cycle immediately and verify the warranty path before your return window closes.
The daily-driver strengths
- Quiet operation is the top praise — 11 owners mention it
- Perfect daily size for two people using the quick wash
- Stainless tub for durability and odor resistance
Know the risk
- Recurring error codes reported by a minority
- Customer service can route to an unresponsive third party
- Cleaning performance is mixed across owners
Best suited for: couples wanting a quiet, budget-friendly daily washer.
Verify early if: you buy — test the electronics in week one.
10. Avanti Built-In Dishwasher 18-Inch
The USA-made compact with a drop-down metal door and a serious feature list.
The standout structural feature here is the drop-down metal door — a design that feels more substantial than the plastic-front alternatives in this width class. Owners who use it nightly simply say they love it, and the Made-in-USA label adds a layer of confidence for buyers who prefer domestic manufacturing. It holds 8 standard place settings with a silverware basket and cup tray included.
The control panel is where this machine punches above its weight. Six automatic cycles (Regular, Automatic, Super, Intensive, Delicate, Rinse) combine with a delayed start and three extra wash options — Hi Temp Wash, Sanitize, and Extra Dry. Add the eco half-load mode and a rinse aid dispenser plus nylon-coated upper and lower racks, and you have a compact unit loaded with features you would expect on a pricier machine. The 53 dB noise rating keeps it in the conversational range.
The honest caveat is build quality at the edges. Reviewers point out the door and sides use very thin metal that can arrive dented and bent from shipping, and one unit’s latch broke after two months of use. These are fit-and-finish complaints rather than cleaning failures — owners who got an undamaged unit describe it as a good enough washer for the price. Inspect the delivery thoroughly before your installer commits, since returning after installation is a hassle.
The feature-dense compact
- Drop-down metal door feels more substantial than rivals
- Six cycles plus Sanitize, Extra Dry, and half-load modes
- Made in the USA for domestic-buying preference
Handle with care
- Thin metal door and sides dent easily in shipping
- Occasional latch failure reported after months
- Returns are tough once installation begins
Reach for it if: you want a USA-made compact with a full feature set.
Inspect hard if: you order — shipping damage is the recurring theme.
Understanding the Specs
Wash Cycles and Options
Noise Level in Decibels
Noise is measured in decibels (dB), and the scale is logarithmic, meaning every few decibels is a noticeable jump in perceived loudness. A 52 dB machine is quiet enough for normal conversation; a 47 dB unit is the kind you forget is running in an open-concept home. If your kitchen shares a wall with a living room or bedroom, prioritize the lower number — it is the spec you will appreciate every single night.
Tub Material and Racks
The tub material defines durability and odor resistance. Stainless steel holds heat better for drying and resists the smells that plastic tubs can develop over time. Some machines use a hybrid design — stainless walls with a plastic floor — to trim cost. Rack material matters too: metal racks with nylon coating slide smoothly and resist rust, while all-plastic racks are lighter but can warp. Adjustable upper racks are the unsung hero for anyone loading tall stemware or bulky pots.
Place Settings and Energy Use
Place settings is the standardized capacity measure — 8 place settings suits a couple, 12 handles a family of four, and 14 gives you room for entertaining. Energy Star certification means the machine meets efficiency standards, but the actual kilowatt-hours per year figure tells you the real operating cost. A machine rated at 234 kwh versus 240 kwh per year is a small but real difference if you run it daily.

Final Thoughts: The Verdict
For most buyers, the built dishwasher winner is the EdgeStar 18 Inch, because 122 owners praise its cleaning performance — the most consistent record in this category. If you want near-silent operation and have a standard 24-inch opening, choose the Sharp SDW6726MS at 47 dB, the quietest unit here. For a growing family needing maximum capacity, the Kenmore 24″ offers 14 place settings and adjustable racks. Whichever you pick, run a full test cycle on day one before your return window closes — that habit protects you from the occasional defective unit that shipping can hide.
