Best 18 Inch Dishwasher: Top Picks Compared
Our top picks are the COMFEE 18 Inch Built-In Dishwasher, the COMFEE’ 18″ Built-In Dishwasher, and the Honeywell 18 Inch Built-In Dishwasher.
Pros
- Exceptional cleaning performance across all wash cycles with impressive results on heavily soiled dishes
- Surprisingly spacious interior for an 18-inch model with flexible loading options for various dishware sizes
- Noticeably quiet operation at 52dB makes it perfect for kitchens adjacent to living spaces
- Solid build quality with smooth-gliding racks and premium stainless steel construction
- Straightforward controls and clear installation documentation for hassle-free setup
Cons
- 18-inch size is not standard, so careful measurement of your kitchen opening is essential before purchase
- Limited to 8 place settings compared to full-size 24-inch dishwashers, which may not suit larger households
- Requires dishwasher-specific detergent, and regular dish soap can cause operational problems
The COMFEE 18-inch built-in dishwasher is purpose-built for homeowners with smaller kitchens, apartments, and compact spaces who refuse to compromise on cleaning performance. This Energy Star certified model combines practical design with reliable functionality, making it an excellent choice for individuals and small families seeking an affordable, space-saving solution.
Performance is where this dishwasher truly shines. The six wash cycles, including Heavy, Normal, Eco, Delicate, Quick, and Rinse, provide flexibility for any load type. Real users consistently report excellent cleaning results on dishes, glasses, and cookware, with the heated dry function delivering cabinet-ready dishes every time. The Hi-Temp hygiene cycle reaches 136 degrees Fahrenheit, making it ideal for sanitizing baby bottles and children's dinnerware. The 1-hour quick wash cycle is perfect for busy households needing clean dishes fast.
Design and build quality exceed expectations for the price point. The stainless steel tub feels premium and resists staining, while the adjustable upper rack accommodates taller items and deep cookware up to 1.97 inches of adjustment. The lower rack holds plates up to 13.78 inches, and the compact 18-inch footprint measures 22.6 inches deep, 17.6 inches wide, and 32.4 inches tall. At just 52dB, this dishwasher runs remarkably quietly, making it ideal for open-concept kitchens and apartments with nearby living spaces.
The main consideration is that this is not a standard 24-inch dishwasher, so accurate measurement of your installation space is critical before ordering. With 8 place settings and 4.9 gallons capacity, it works well for individuals, couples, and small families but may require more frequent cycles for larger households. Additionally, only dishwasher-specific detergent should be used, as regular dish soap can cause operational issues.
The COMFEE 18-inch built-in dishwasher represents exceptional value for space-conscious buyers who prioritize performance and quiet operation. Its combination of reliable cleaning, solid construction, Energy Star efficiency, and compact design makes it the smart choice for modern small-space living.

Measure Before You Buy: This is NOT a standard 24-inch dishwasher. Measure your installation opening carefully in width, depth, and height to ensure proper fit. The 17.6-inch width is significantly narrower than conventional dishwashers.
Installation Considerations: Installation is straightforward with clear documentation included. You will need a 120-volt electrical outlet and standard dishwasher plumbing connections. Some users recommend using thread sealant like blue monster tape for water connections to prevent leaks.

Pros
- Space-saving 18-inch design maximizes kitchen efficiency while maintaining 8 place setting capacity
- Exceptionally quiet at 52dB, making it one of the quietest dishwashers for apartments and small homes
- Adjustable upper rack with 1.97-inch lift accommodates tall cookware and non-standard dishware easily
- Energy Star certification reduces water and electricity consumption compared to standard models
- Hi-Temp sanitize cycle reaches 136°F, perfect for sterilizing baby bottles and children's dishes
Cons
- Slimline capacity of 8 place settings is smaller than full-size 12-14 place setting models, limiting batch washing

The COMFEE' 18-inch built-in dishwasher is purpose-built for homeowners with space constraints, from apartment dwellers to those with galley kitchens or under-sink configurations. This compact appliance delivers genuine functionality without the bulk, making it an excellent alternative to full-size models for individuals and small families.
What sets this dishwasher apart is its intelligent engineering. The adjustable upper rack rises up to 1.97 inches to clear deep pots and pans, while the lower rack handles plates up to 13.78 inches. The 6 wash cycles cover every scenario: Heavy for baked-on grime, Eco for daily loads, Delicate for glassware, and Quick for lightly soiled dishes. The Hi-Temp sanitize function reaching 136°F makes it particularly valuable for parents needing to sterilize baby bottles and children's dishes.
The heated dry function works on nearly all cycles, ensuring dishes exit cabinet-ready without manual drying. At 52dB, this dishwasher operates quietly enough for open-concept living spaces, a significant advantage over noisier compact models. Energy Star certification means lower monthly utility bills without compromising cleaning performance.
The primary limitation is capacity. With 8 place settings versus 12-14 in full-size models, you'll run more frequent cycles if you have a larger household. The push button interface is straightforward but lacks smart home integration some consumers now expect. Additionally, the relatively small review count means less community feedback compared to established brands.
The COMFEE' 18-inch built-in dishwasher represents smart value for apartment residents, small households, and anyone prioritizing space efficiency and quiet operation. It delivers reliable cleaning, thoughtful design features, and Energy Star savings at an accessible price point.
Dimensions and Installation: 22.6 inches deep by 17.6 inches wide by 32.4 inches high with adjustable legs for leveling. Designed for built-in under-counter installation with 120-volt standard electrical connection.
Capacity and Loading: 8 place settings with 4.9-gallon water capacity. Upper rack adjusts up to 1.97 inches for tall cookware. Lower rack accommodates plates and dishes up to 13.78 inches in height. Includes cutlery basket and versatile cup shelves.

Performance and Efficiency: 52dB noise level. Energy Star certified. Stainless steel tub construction. Push button controls with LED digital display. 1-year manufacturer warranty.
Is This Right for You? Choose the COMFEE' 18-inch if you have limited kitchen space, live in an apartment, prefer quiet operation, or have a small household. This model excels for those who value efficiency and affordability over maximum capacity.
Installation Considerations: This is a built-in model requiring under-counter integration. Verify your kitchen cabinet dimensions match 22.6 inches deep, 17.6 inches wide, and 32.4 inches high. Ensure 120-volt electrical outlet access and proper water supply and drain connections. Professional installation is recommended.
Detergent and Maintenance: Use only dishwasher-specific detergent, never regular liquid dish soap. The manufacturer emphasizes this to prevent damage. Regular cleaning of spray arms and drain filters maintains optimal performance.
Best Use Cases: Ideal for couples, small families, apartment living, and secondary kitchens. The Hi-Temp sanitize function makes it particularly valuable for parents with infants. Energy Star certification benefits environmentally conscious consumers and those seeking lower utility costs.

- Heated Dry function ensures thorough drying without additional energy consumption or manual intervention
- Multiple specialized cycles including Eco and Delicate options provide flexibility for different load types
- Quiet operation at 52 dB makes it suitable for open-concept kitchens and noise-sensitive environments
- Energy Star certification reduces utility bills while maintaining strong cleaning performance
Cons
- Compact 18-inch size limits total capacity compared to full-size 24-inch models, requiring more frequent runs for large families
- Requires dishwasher-specific detergent, and using regular dish soap can cause operational problems and damage
- Limited information on long-term reliability and warranty coverage based on available product data
The COMFEE 18-inch built-in dishwasher is a compact solution designed for homeowners with limited kitchen space who refuse to sacrifice cleaning power or convenience. This slimline model delivers surprising functionality with 8 place settings, making it suitable for small to medium households, couples, or apartment dwellers seeking reliable daily dishwashing without the footprint of a full-size unit.
The standout feature is the adjustable upper rack that extends up to 1.97 inches, allowing you to load deep pots, pans, and cookware that typically require hand washing. Combined with the lower rack's ability to accommodate plates up to 13.78 inches, this dishwasher proves that compact doesn't mean limited. The 6 wash cycles, including Heavy, Eco, Delicate, and Quick options, provide flexibility for everything from delicate glassware to baked-on cookware, while the Hi-Temp sanitize cycle reaching 136°F is excellent for baby bottles and hygiene-sensitive loads.
Build quality centers on a stainless steel tub that resists staining and odors, paired with a digital control panel featuring an LED display for easy cycle selection. The Heated Dry function delivers cabinet-ready dishes automatically, eliminating the need for towel drying on most cycles. At 52 dB, the noise level is respectably quiet for an 18-inch model, making it suitable for open-concept living spaces. The 24-hour delay start and 1-hour Quick Wash options add scheduling flexibility for busy households.
The primary drawback is that 18-inch capacity, while impressive for its size, still requires more frequent cycles than full-size 24-inch models for larger families. Additionally, the product requires dishwasher-specific detergent, and using regular dish soap can cause damage and operational issues. Limited warranty information is available from the product data provided.
The COMFEE 18-inch built-in dishwasher is an excellent value for space-conscious buyers who prioritize cleaning performance and modern features. Energy Star certification keeps utility costs down, while the combination of specialized cycles and heated drying makes daily dishwashing more convenient. If you have the counter space for a full-size unit, that may offer better value, but for apartments, small kitchens, or secondary kitchens, this compact model delivers solid performance and reliability at an accessible price point.
Dimensions: 22.6 inches deep x 17.6 inches wide x 32.4 inches high with adjustable legs for precise installation height.
Capacity: 8 place settings with 4.9 gallons water capacity per cycle. Upper rack adjusts up to 1.97 inches, lower rack accommodates plates up to 13.78 inches in height.
Wash Cycles: Heavy, Normal, Eco, Delicate, Quick, and Rinse cycles. Additional functions include Heated Dry, Hi-Temp (136°F/58°C sanitize), and 1-hour Quick Wash option with 24-hour delay start.
Construction: Stainless steel tub with plastic and steel exterior components. Push button controls with LED digital display. Noise level: 52 dB. Includes cutlery basket and versatile cup shelves.
Certifications: Energy Star certified and NSF approved for hygiene standards. Installation type: Built-in under-sink or cabinet configuration.
Who Should Buy This Model: This dishwasher is ideal for apartment dwellers, small household owners, couples, and anyone with limited kitchen space who still wants modern features and reliable cleaning performance. It's also excellent as a secondary dishwasher in larger homes or kitchens with space constraints.
Key Considerations: Measure your available space carefully before purchasing, as 18-inch models fit specific cabinet configurations. Verify that your kitchen layout accommodates the 22.6-inch depth and 32.4-inch height. Consider whether your household generates enough daily dishes to justify frequent cycles, as 8 place settings may require running the dishwasher multiple times for larger families.
Detergent Requirements: Always use dishwasher-specific detergent tablets or powder. Regular liquid dish soap will cause foaming, overflow, and potential damage to the unit. This is critical for maintaining warranty coverage and ensuring proper operation.
Cycle Selection Tips: Use the Eco cycle for daily loads to reduce water and energy consumption. Select the Heavy cycle for baked-on food and cookware. The Delicate cycle protects fine glassware and dishes. The Hi-Temp sanitize function is perfect for baby bottles, cutting boards, and items requiring high-temperature cleaning.
Maintenance: Run the Rinse cycle periodically to clean the interior. Check the filter basket after each cycle and remove debris. The stainless steel tub naturally resists odors, but occasional cleaning ensures optimal performance. Take advantage of the 24-hour delay start to run cycles during off-peak energy hours if your utility company offers time-based rates.
Pros
- Exceptional value for price with surprisingly large capacity and multiple wash options
- Quiet operation at 42dB makes it suitable for open-concept kitchens and small spaces

- Some users reported error codes on initial use, though manufacturer support resolves issues quickly
The Honeywell HDS18W is a compact 18-inch built-in dishwasher designed for homeowners with limited kitchen space, apartment dwellers, and RV enthusiasts seeking a reliable cleaning solution. This space-saving model fits standard under-counter openings while maintaining practical capacity and functionality that belies its compact footprint.
The standout feature is its versatility paired with affordability. Six washing programs cover diverse needs including pots and pans, normal wash, delicate china, quick wash, rinse only, and energy-saving cycles. The stainless steel tub resists corrosion and staining, while the 8 place setting capacity with removable cutlery basket adapts to various load sizes. Real-world performance impresses with dishes emerging clean and dry, and the quiet 42dB operation won't dominate your kitchen soundscape.
Build quality reflects its price point with plastic racks and nylon baskets rather than premium materials, yet users consistently report durability and reliable operation. The push-button controls with recessed handles offer intuitive usability, and the 24-hour delay start feature provides scheduling flexibility. Weighing just 70 pounds, installation proves straightforward with adequate space for plumbing connections behind the unit.
Minor drawbacks include occasional lower basket wheel misalignment and limited capacity compared to standard 24-inch models. Some users reported initial error codes, though Honeywell's responsive customer service typically resolves these quickly. The 1-year warranty provides basic protection, though longevity appears solid based on user experiences.
This dishwasher represents smart value engineering. It's ideal for small households, vacation homes, and anyone prioritizing budget without sacrificing cleaning performance or quiet operation. Energy Star certification further sweetens the deal for cost-conscious buyers seeking long-term savings.

Performance and Efficiency: Stainless steel tub interior. 42dB noise level for quiet operation. Energy Star certified with low power consumption. Recessed handle design. Model number HDS18W manufactured by BHRS Group LLC. 1-year manufacturer warranty included.
Is This Right for You? This dishwasher suits small households, apartments, RVs, vacation homes, and anyone with limited kitchen space. It's ideal if you prioritize quiet operation and energy efficiency over maximum capacity. Perfect for upgrading older 18-inch models or adding dishwashing convenience where space is constrained.
Installation Considerations: Verify your under-counter opening measures 18 inches wide to ensure proper fit. Confirm adequate space behind the unit for drain and feed hose routing. Standard 115V outlet access is required. Installation is straightforward enough for most homeowners, though professional installation is recommended if you're unfamiliar with plumbing connections.
Maintenance Tips: Regularly check lower basket wheels to ensure they stay properly aligned on rails. Use appropriate detergent for your water hardness level. Run the rinse-only cycle occasionally to maintain cleanliness. The stainless steel tub requires minimal special care beyond standard dishwasher maintenance.
Performance Expectations: Expect excellent cleaning performance for everyday dishes and glassware. The pots and pans cycle handles heavy-soiled cookware effectively. Delicate china cycle provides gentle washing for fragile items. Very large pots or oversized mixing bowls may require hand washing due to capacity limitations.
Pros
- Space-saving 18-inch footprint fits tight kitchens and bar areas.
- Six flexible wash programs cover everything from glassware to heavy pots.
- Stainless steel tub and racks improve durability and drying efficiency.
- Energy Star certified to help save on power and water.
- 24-hour delay start adds scheduling convenience.
Cons
- Eight place setting capacity may be tight for bulky cookware or large family dinners.
- Push button controls are straightforward but lack touchscreen or smart features.
- Requires careful measurement of existing cabinetry because 18-inch models are less common than full-size units.
The Honeywell HDS18SS is an 18-inch compact dishwasher made for kitchens where a standard 24-inch model simply won't fit. It washes up to eight place settings and works as a built-in, under-counter unit, making it a strong choice for apartments, small homes, offices, and vacation rentals.
Six wash programs are built in: heavy, normal, eco, glass, rapid, and rinse. That variety covers everyday plates, delicate stemware, and quicker refreshes. The stainless steel tub helps hold heat and dry dishes efficiently, and the 42 dB noise level stays quiet enough for open kitchens.
The design includes two racks and a removable cutlery basket, so you can organize flatware and dishes without losing usable space. Push button controls make cycle selection straightforward, while the 24-hour delay start lets you set the dishwasher to run at a more convenient time or during lower energy demand.
The main compromise is capacity. Eight place settings serve a small household, but large stockpots, baking sheets, and oversized cookware may still need hand washing. Also, because this is an 18-inch model, measure your cutout carefully to confirm the dimensions fit your cabinetry before installation.
For buyers who need a space-efficient dishwasher with solid wash flexibility and a stainless steel interior, the Honeywell HDS18SS delivers dependable performance without taking over the kitchen. It is a practical, well-rounded unit for smaller spaces.

Designed specifically for small kitchens, apartments, RVs, and single or couple households, this slimline model proves that compact doesn't mean compromising on capability or features.
What sets this dishwasher apart is its thoughtful engineering. The 8 place setting capacity accommodates larger plates, pots, and pans up to 11 inches in height, while the 6 wash programs (Heavy, Normal, ECO, Delicate, Quick, and Rinse) address virtually every cleaning scenario. The Hi-Temp hygiene cycle reaching 136°F is particularly valuable for sanitizing baby bottles and children's dinnerware, while the heated dry function ensures dishes come out completely dry without additional effort. At just 52dB, it operates so quietly that users frequently comment on being pleasantly surprised by the silent performance.
Build quality is solid with a stainless steel tub that resists staining and corrosion. The digital control panel with LED display is intuitive to use, and the push-button controls are responsive and reliable. The unit's 15.5 gallons per hour water consumption combined with Energy Star 7.0 certification means lower water and electricity bills without sacrificing cleaning power. Customer feedback confirms that dishes emerge spotless even when heavily soiled, and the machine handles everyday dishware, glassware, bakeware, and utensils with equal effectiveness.
The main limitation is capacity, which suits small households but may require more frequent cycles for families of four or more. Additionally, this model requires dishwasher-specific detergent rather than regular dish soap, which is standard practice but worth noting. Some delivery concerns have been reported by a small number of users, though the product itself consistently receives praise for quality and performance when properly installed.

Is This Dishwasher Right for You? This model is ideal if you have limited kitchen space, live in an apartment, own an RV, or simply don't need a full-size dishwasher. It's perfect for couples, single professionals, and small households that prioritize efficiency and quiet operation over maximum capacity.
Key Considerations: Verify that your under-counter space matches the dimensions of 22.6D x 17.6W x 32.4H inches. Ensure you have a 120-volt electrical connection available. Plan to use only dishwasher-specific detergent to avoid operational issues. Consider your typical load size, as this model holds 8 place settings rather than the 12-14 of full-size units.
Installation and Maintenance: Professional installation is recommended for under-counter built-in models. The stainless steel tub requires minimal maintenance but benefits from occasional cleaning to prevent odor buildup. The adjustable legs allow for leveling on uneven floors. Keep the door gasket clean and dry between uses to maintain the seal.
Energy and Cost Savings: Energy Star 7.0 certification means lower annual electricity costs compared to standard dishwashers.

An 18-inch model saves 6 inches of cabinet space and uses less water per load. A 24-inch model holds about 12 to 14 place settings, so it suits larger families.
How to Choose an 18 Inch Dishwasher
The right choice comes down to measuring the opening, counting place settings, looking at programs, and checking the noise.
- Measure the Opening: Check the width, height, and depth.
- Count Place Settings: Most hold about 8 settings.
- Look at Programs: ECO, quick, and heavy cycles are the most useful.
- Check the Noise: Quieter models suit open kitchens.
- Confirm the Hookups: Make sure your plumbing and power are in the right place.

Who Should Choose a Compact Model
A narrow model is ideal when cabinet space is limited or when you run smaller loads. Singles and couples often find that they can run it more frequently without wasting water. Larger families may be better served by a 24-inch model that holds more dishes per cycle.
Measuring and Installation
Measure the opening width, height, and depth before buying. Most compact models need an opening just over 18 inches wide and around 34 to 35 inches high, but check the manufacturer’s specifications. Make sure water supply, drain line, and electrical connection are accessible. Many retailers offer installation, which can save time.
Loading for Best Results
Load plates facing the center on the lower rack and place cups and glasses on the upper rack at an angle. Keep tall items from blocking the spray arms, and avoid nesting bowls together.
Care and Maintenance
Clean the filter every few weeks, use rinse aid, and run a dishwasher cleaner once a month. Wipe the door seal regularly to stop odors from developing.
Energy-Saving Tips
Run full loads when possible and use eco cycles for lightly soiled dishes. Skip heavy pre-rinsing; scraping food off is enough for most modern detergents.
Common Mistakes to Avoid
Do not buy without checking the exact cutout size. Avoid overloading the racks, and compare noise ratings if you are choosing an 18 inch dishwasher for an open-plan space.
Final Verdict on the Best 18 Inch Dishwasher
The best 18 inch dishwasher for most small kitchens is the COMFEE’ Energy Star. Choose the Honeywell HDS18SS for simplicity or the Midea for an ECO program.
