More Details on Our Top Picks
BLACK+DECKER 18-Inch Portable Dishwasher, Energy Star, BPD8B, Black
This BLACK+DECKER model stands out for its compact size and robust features, making it a top choice for apartment dwellers and small kitchens. It offers six wash cycles and an adjustable upper rack, providing enough versatility for everyday dishes. Its quick connect faucet setup simplifies installation, a clear advantage over more complex models like the EUHOMY, which lacks a built-in tank. However, at 45 dB, it is louder than some competitors, and its weight (116 pounds) can make moving cumbersome. Despite these tradeoffs, its stainless steel tub boosts durability, and the multiple cycle options cater to diverse cleaning needs. Compared to the COMFEE’, it has a slightly larger capacity and more cycle choices, but it sacrifices some quietness.
Pros:- Compact size perfect for small spaces
- Multiple wash cycles for versatile cleaning
- Quick connect faucet hookup for easy installation
- Durable stainless steel tub
Cons:- Relatively loud at 45 dB
- Heavy weight making it difficult to move
Best for: Small apartment residents who need a durable, easy-to-use dishwasher with multiple cycles.
Not ideal for: Users seeking a lightweight, ultra-quiet model or those with very limited counter space, as it is relatively heavy and loud.
- Installation Type:Freestanding
- Capacity:8 load
- Controls:Push Button
- Noise:45 db
- Cycle Options:6
- Item Dimensions:23.62″D x 17.64″W x 35.63″H
Our verdict“This model suits small space dwellers who need reliable performance and flexible cleaning options but don’t mind a bit of noise.”
SPT SD-9263WA 18-Inch Portable Dishwasher with ENERGY STAR, 6 Wash Programs, 8 Place Settings, Stainless Steel Interior – White
The SPT SD-9263WA offers a compelling blend of energy savings and spaciousness, making it ideal for households conscious of utility costs. Its ENERGY STAR certification and six wash programs ensure efficient, versatile cleaning. Its 8-place setting capacity surpasses smaller models like the COMFEE’ and EUHOMY, providing more room for larger families or frequent entertainers. The quick connect faucet makes setup straightforward, yet it requires a separate faucet adapter and isn’t designed for built-in installation. At 52 dB, it is somewhat louder than other models like the EUHOMY, which operates at 40 dB. Compared to the BLACK+DECKER, it offers similar capacity but with better energy ratings, though it is slightly heavier and bulkier.
Pros:- Energy Star rated for savings
- Large capacity fits up to eight place settings
- Six wash programs for flexible cleaning
- Easy installation with quick connect
Cons:- Requires separate faucet adapter
- Louder at 52 dB compared to quieter models
Best for: Energy-conscious families needing a spacious, efficient dishwasher with multiple programs.
Not ideal for: Small households or those who prioritize ultra-quiet operation, since it runs louder and has a larger footprint.
- Capacity:8 place settings
- Wash Programs:6
- Installation Type:Freestanding
- Noise Level:52 dB
- Energy Star Certified:Yes
- Item Dimensions:24″D x 18″W x 36″H
Our verdict“This dishwasher is a smart pick for larger households seeking energy efficiency and capacity, with some noise tradeoff.”
COMFEE’ Countertop Dishwasher, Energy Star Portable with 6 Place Settings and 8 Washing Programs, Black
Compared with larger models like the BLACK+DECKER, the COMFEE’ offers a more compact footprint, making it ideal for dorms, RVs, or small apartments. Its 6 place settings and 8 programs, including eco and baby-care, provide versatile cleaning in a small package. The rapid 45-minute cycle suits quick turnaround needs, and its energy efficiency reduces utility bills. However, it requires a faucet adapter for setup, which may be a hassle for some users, and its capacity limits it for bigger families. Additionally, factory testing can leave water inside, requiring a quick drain before use. This model’s smaller size makes it less suitable for large households but perfect where space is at a premium.
Pros:- Very compact for small spaces
- Multiple wash programs including eco and baby-care
- Fast cleaning cycle in 45 minutes
- Energy Star rated
Cons:- Limited capacity for larger households
- Requires faucet adapter for installation
Best for: Single users or small households needing a portable, efficient dishwasher for limited spaces.
Not ideal for: Large families or those needing to wash many dishes at once, due to its limited capacity.
- Dimensions:H17.2″×W21.7″×D19.7″
- Capacity:6 place settings
- Washing Programs:8
- Water Usage:2.77 gallons per cycle
- Maximum Temperature:154°F
- Energy Star:Yes
Our verdict“This model fits small households or portable needs perfectly, with quick cycles and multiple programs, but isn’t designed for larger loads.”
COMFEE’ Countertop Dishwasher, 6 Place Settings, Energy Star
Fitting 6 place settings with multiple cycles, the COMFEE’ offers a flexible solution for small households, dorms, and RVs. Its diverse modes, including heavy, eco, and baby-care, compare favorably to the EUHOMY, which focuses more on quiet operation than cycle variety. Installation is straightforward, with a faucet connection and optional built-in setup, but it requires a suitable faucet adapter. While the noise level is moderate at 4/5, some users may find it slightly louder than the EUHOMY’s whisper-quiet operation. Its limited capacity makes it less suitable for larger families, but for individuals or couples, it provides versatile cleaning with minimal fuss.
Pros:- Compact size for small spaces
- Multiple wash cycles including eco and heavy
- Flexible installation options
- Childproof lock for safety
Cons:- Limited capacity for larger households
- Requires a faucet adapter for installation
Best for: Small households or renters needing an easy-to-install dishwasher with multiple cycles.
Not ideal for: Large families or users seeking a very quiet model, as noise levels are moderate and capacity limited.
- Capacity:6 place settings
- Water Usage:2.77 gallons per cycle
- Installation Type:Countertop
- Noise Level:Moderate (4/5)
- Additional Features:Childproof Lock
Our verdict“This dishwasher is well-suited for small households seeking a versatile, easy-to-install model with multiple programs.”
EUHOMY Countertop Dishwasher Portable, 6 Programs, 40 dB, No Hookup
The EUHOMY stands out for its exceptionally quiet operation at 40 dB, making it an excellent choice for open-concept kitchens or shared living spaces. Its built-in 5L tank allows for stand-alone operation without immediate faucet hookup, providing high flexibility—ideal for RVs, apartments, or situations where plumbing isn’t readily accessible. It offers six programs, including eco and heavy-duty, and can wash over 30 items per load, surpassing some smaller models in capacity. However, its lack of a permanent hookup limits continuous use, and its slightly larger dimensions demand more counter space. Compared to the COMFEE’ models, it excels in noise reduction but sacrifices some capacity and ease of connection, which might matter for users with limited space or plumbing options.
Pros:- Extremely quiet at 40 dB
- Built-in 5L water tank for standalone operation
- Multiple cycles including eco and heavy
- Washes over 30 items per load
Cons:- Requires separate faucet adapter for hookup
- Limited to small loads, less ideal for large families
Best for: Users prioritizing ultra-quiet operation and flexible, no-connection setup for apartments or RVs.
Not ideal for: Those needing a built-in, permanently plumbed dishwasher or larger capacity for heavy daily loads.
- Capacity:30+ items
- Dimensions:16.83 × 16.73 × 18.03 inches
- Water Tank Capacity:5L (1.32 gallons)
- Noise Level:40 dB
- Cycle Time:29 minutes
- Faucet Connection:G3/4-inch (adapter sold separately)
Our verdict“This model excels in quiet operation and flexible setup, best suited for small spaces where noise is a concern, but not for large daily loads.”
COMFEE’ Portable Countertop Dishwasher with 5L Water Tank, 6 Programs, 360° Dual Spray, High-Temp & Air-Dry Function, White
This COMFEE’ model excels in small spaces like RVs, dorms, or tiny kitchens where traditional dishwashers won’t fit. Its compact design and built-in 5-liter water tank eliminate the need for plumbing, making installation straightforward and portable. Compared to the BLACK+DECKER BCD6W, it offers fewer place settings but shines in adaptability with six wash programs, including high-temp hygiene and air refresh modes. The tradeoff is its limited capacity, which might require frequent refilling for larger loads. Its noise level of 62 db is acceptable but noticeable in quiet environments, and its small size isn’t suitable for heavy-duty cleaning or larger households. Overall, this pick is ideal for users prioritizing convenience, mobility, and space-saving features over high capacity.Pros:- Compact and portable, perfect for small or mobile spaces
- Multiple wash programs including high-temp hygiene and air refresh
- Easy to connect to water tanks or faucets, no installation needed
Cons:- Limited water capacity requires frequent refilling
- Noise level of 62 db may be noticeable in quiet settings
Best for: Individuals with very limited space, such as RV owners, students in dorms, or tiny apartment dwellers who need occasional dishwashing without permanent plumbing.
Not ideal for: Families or anyone needing to wash large loads regularly, as the 5-liter capacity and small size limit efficiency for bigger households.
- Capacity:5 liters
- Installation Type:Countertop
- Additional Features:Adjustable Rack, Touch Panel, Hi-temp Wash, Air Refresh, 360° Cleaning
- Controls Type:Full Panel
- Noise:62 db
- Cycle Options:Delicate, Fruit, Hygiene, Normal, Rapid
Our verdict“This model is best suited for users needing a space-efficient, portable dishwasher for small loads and limited spaces.”
BLACK+DECKER Countertop Dishwasher, Energy Star Certified, BCD6W, White
The BLACK+DECKER BCD6W stands out for its seven wash cycles, which include options like Eco and Intensive that cater to a variety of cleaning needs. Its capacity of six place settings makes it more suitable for small families or households that regularly wash a few dishes at once. Compared to the COMFEE’ model, it offers more cycle options and a slightly larger capacity but requires a standard faucet hookup, reducing portability and convenience for those without direct plumbing access. Noise levels might be a concern at higher settings, and its size—while compact—still demands counter or cabinet space. The stainless steel interior adds durability, but the need for faucet connection limits its mobility. This dishwasher suits users who want more cycle versatility and a slightly larger load capacity but are okay with the fixed installation.Pros:- Seven diverse wash cycles for different cleaning needs
- Easy to install with quick connect faucet hookup
- Stainless steel interior enhances durability and looks sleek
Cons:- Limited to 6 place settings, not ideal for larger families
- Requires connection to a faucet, reducing portability
Best for: Small families or couples wanting a flexible, easy-to-use dishwasher with multiple cleaning options and a bit more capacity than ultra-portable models.
Not ideal for: Users in tiny apartments or RVs who need a fully portable, no-faucet setup, or those who lack direct access to a standard kitchen faucet.
- Dimensions:21.5” x 21.7” x 17.2”
- Capacity:6 place settings
- Weight:46.2 lbs.
- Color:White
- Energy Star Certified:Yes
- Wash Cycles:7
Our verdict“This dishwasher makes the most sense for small households seeking a versatile, relatively easy-to-install solution with larger capacity than ultra-compact models.”

Factors to Consider When Choosing Countertop Dishwasher Portable Full Size
Choosing the right countertop dishwasher involves balancing several factors to meet your specific needs. Beyond just capacity, consider how installation requirements, water hookup options, noise levels, and energy consumption will impact daily use. Being aware of common pitfalls—like underestimating water needs or choosing a model that’s too large for your space—can help you avoid costly mistakes. The following sections highlight key considerations to help you make a more informed decision.Size and Capacity
While these dishwashers are all marketed as ‘full size,’ their actual capacities can vary. Consider how many place settings you typically wash at once—larger capacities mean fewer loads but also larger units that may take up more counter space. If space is tight, a slightly smaller model with efficient use of interior space might serve better. Be mindful of your kitchen layout and storage options to choose a size that fits comfortably without cluttering your countertop.
Water Hookup and Portability
Some models require permanent water hookups, which can complicate installation or limit portability. Others offer a no-hookup design with water tanks, ideal for renters or those who want a truly portable option. Think about your living situation—if you rent or move frequently, a model with a water tank may be more practical. Conversely, if you have a dedicated space with plumbing, a built-in hookup can save time and effort.
Performance and Wash Programs
Not all dishwashers are created equal in terms of cleaning power. Look for models with multiple wash programs tailored to different loads—heavy, eco, quick, etc. Higher-end models tend to have more thorough and versatile cleaning options, which can be worth the investment if you have diverse needs. Consider whether features like high-temperature washes or air-dry functions are important for your hygiene and convenience.
Noise Level
If your kitchen is part of an open plan or shared space, noise can be a key factor. Quieter models typically operate at 40-45 dB, which is less disruptive during conversations or work. Cheaper models may be louder, which might be bothersome during evening hours or in small apartments. Balance your preference for quiet operation with budget constraints and available features.
Energy Efficiency and Cost
Energy Star certification is a good indicator of efficiency, leading to lower utility bills over time. While these models tend to cost more upfront, the savings on water and electricity can offset the initial investment. Be aware that some features—like heated drying or longer wash cycles—consume more energy. Match your budget with your long-term cost considerations to make the best choice.
Frequently Asked Questions
Can I use a countertop dishwasher without a permanent water hookup?
Yes, many countertop dishwashers are designed with water tanks that allow for portable use without needing a plumbing connection. These models are ideal if you rent or prefer a unit that can be moved easily. Keep in mind that tank capacity varies, so choose one that fits your typical load size to avoid frequent refills. While they add convenience, tank models may require more maintenance and monitoring of water levels.
How noisy are these portable full-size countertop dishwashers?
Noise levels can differ significantly between models, with quieter units operating around 40-45 dB, making them suitable for open-plan spaces. Cheaper or older models may produce noise upwards of 55 dB, which can be disruptive during conversations or work. If noise is a concern, look for models specifically rated for quiet operation, especially if your kitchen doubles as a living or workspace.
Are full-size countertop dishwashers energy-efficient?
Most newer models are designed with energy efficiency in mind, often featuring Energy Star certification. These units use less water and electricity, reducing long-term costs. Higher efficiency models may have additional features like eco modes or sensor-based wash cycles, which further save resources. When choosing a dishwasher, consider the balance between upfront cost and long-term savings from lower utility bills.
What maintenance is required for these portable dishwashers?
Regular maintenance includes cleaning the filter, checking spray arms for clogs, and descaling if you have hard water. Some models have removable parts that are easy to clean, which helps maintain performance. Ensuring proper drainage and using recommended detergents will extend the lifespan of your unit. Routine upkeep prevents common issues like odor buildup or reduced cleaning effectiveness.
Is a larger capacity always better for a countertop dishwasher?
Not necessarily. While a larger capacity reduces the number of loads, it can also mean a bigger footprint that may not fit well in smaller kitchens. Smaller units are more compact and easier to store but might require more frequent washes. The best choice depends on your household size, typical load volume, and available countertop space—balance these factors to avoid over- or under-sizing your dishwasher.
Conclusion
For buyers seeking the best overall performance and balance, the BLACK+DECKER 18-Inch Portable Dishwasher makes a compelling choice. Those prioritizing value will appreciate the COMFEE’ Countertop Dishwasher with multiple wash programs at a lower price point. If you want a premium model with extra features like quieter operation and more cycles, the SPT SD-9263WA stands out. Beginners or renters should lean toward models with water tanks for ease of use, such as the EUHOMY Countertop Dishwasher. For those with specific space or noise needs, pay attention to size and decibel ratings—matching these factors ensures your countertop dishwasher complements your lifestyle effectively.
