Are portable dishwashers as good as built-in dishwashers? If you live in a small apartment that does not fit a built-in dishwasher, you want a portable dishwasher for the space. However, you are scared that portables may not be as good – that is wrong.
Portable dishwashers are as good as built-in dishwashers. They can handle the loads in your small household, and you get thorough cleaning without wasting water, space, and energy. However, portable dishwashers are louder and reach up to 50+ decibels compared to full-sized/built-ins.
Note that portable dishwashers are different and larger than compacts. They have wheels and are usually about the size of a mini fridge. You can stick your portable dishwasher in a closet, and some portables are even convertible to full-sized built-ins.
Are portable dishwashers as good as built-in dishwashers?
Portable dishwashers are capable compared to built-in dishwashers. They will keep the kitchen tasks running so smoothly that you forget they are not the full-sized counterpart.
Some portable dishwashers can be pretty much installed in any kitchen. You only have to connect to the faucet and drain to the sink.
If your small household does not generate massive amounts of dirty dishes daily, a portable dishwasher is a better option than conventional built-in dishwashers.
Portables can handle loads, although smaller, you get a thorough cleaning with no excess water, energy, or space consumption. Most portables are designed to clean and dry the dishes more like built-ins. The racks and wash cycles are also similar.
A portable dishwasher consumes as little as 3 gallons, which is about 11 liters, per load. Similar to a built-in and more efficient than handwashing, which consumes up to 27 gallons of water, according to the USGS.
Thus, a portable dishwasher supersedes hand-washing dishes in the sink. This also comes down to the number of dishes washed.
What is the difference between a portable dishwasher and a built-in dishwasher?
If you initiated a portable vs built-in dishwasher contest, built-ins will not get away with so many because some portables are as good.
Portable dishwashers are typically on wheels, making movement from one spot to another, or one room to another more comfortable.
For a portable, you move it next to the sink, hook it to the faucet, and use it. You can as well unhook it and move it back to where its primary location after running.
A typical built-in sits under the kitchen counter and receives water from the sink. A convertible portable can do the same, so it never gets moved. It acts as a trash compactor, only wider, but takes dishes and not trash.
Regarding cost, it is cheaper to buy a portable dishwasher. Built-ins generally cost more. Quality brands cost as high as $1,000+.
In terms of noise, portables are louder. The reason is that built-in dishwashers include insulated surfaces that make most loads run whisper quiet.
Can you use a portable dishwasher as a built-in?
Generally, portable dishwashers with top-mounted controls and load from the top are not convertible to built-ins, which sit underneath your counter.
However, some portable dishwashers can be converted to built-ins. Here is how:
Have a permanent power source
Pick a permanent source of power for the portable dishwasher. You can either install an outlet below your counter or use an existing outlet positioned above your counter. It is better to use an existing outlet if you have no electrical expertise.
You need to drill a large enough hole in the counter for threading through the power cord of the portable dishwasher, which will be placed under the counter.
If you prefer to install an outlet beneath the counter, have a professional complete the steps if you have no electrical experience.
Otherwise, you have to run an independent power line from the breaker box to your new outlet location. Secure the outlet box to a stud, thread through the power line into the box, and connect it to an outlet.
Connect the water line to a permanent source of water
Get a flexible water line, water line adapter, contact cement for connecting the waterline of the portable dishwasher to a permanent hot-water source.
Your first hot water source option is to tap in the hot water line of the kitchen. Your second option is to run the hot water line from your water heater independently.
Build a permanent drainage system
Tap into the drainpipe for the kitchen sink. Cut the PVC drain pipe, and use a pipe adapter, coupler, and contact cement to connect the drain line of the dishwasher to the PVC drain pipe.
Reconnect all the pieces to make an enclosed drain system, and wait for the contact cement to dry before you check for leaks.
Trim your portable dishwasher
You want your portable dishwasher to look like a built-in, so you have to trim it out. Get pre-manufactured trimmer pieces from your local home improvement centers in the cabinet department.
You could also DIY using plywood. However, you would have to stain the trim or paint to match the finish on your cabinets in the kitchen.

What’s the point of a portable dishwasher?
A portable dishwasher is just another regular dishwasher, except that it is not full-sized and is easily moveable when necessary. You hook it to your faucet and start a wash cycle. Portables can be permanently installed to function as built-ins.
Like a built-in, a portable dishwasher can draw clean water and then pump the dirty water into the sink.
Portables are typically noisier than their built-in counterparts. The reason is that most built-ins use insulated surfaces capable of making even heavy loads run so quietly.
Portable dishwashers do not feature this buffer, so you get to hear every swoosh and bump, as well as the hiss during wash, rinse, and dry cycles.
A portable dishwasher is perfect for a small household of about 3 that does not generate too many dirty dishes every day. Built-ins are best for larger households, and cost more for their size.
Do not judge portables by size but by ability. After all, size is the significant difference between a portable and built-in dishwasher.
You also get the squeaky-clean wash without wasting space, water, or energy just like a built-in dishwasher. The racks are similar, and some are adjustable to accommodate taller kitchen utensils.
Why are portable dishwashers cheaper than built-ins?
Portable dishwashers are cheaper than built-ins generally because of size. Limited access to the sink does not really count since some portables are convertible to built-ins.
Portables also cost lower since the general design is for smaller households that do not necessarily need full-sized built-in dishwashers.
How long do built-in convertible portable dishwashers last?
A built-in convertible portable dishwasher typically lasts up to 9 to 16 years with an average of 12 years of life expectancy. The lifespan of a dishwasher is relatively predictable but your machine can reach the 16-year mark with an appropriate maintenance culture.
Remember that not all portables are convertible. If you are buying a dishwasher different from these recommendations, question the retailer or manufacturer about using it as a built-in.
