Labor Cost To Install New Dishwasher

For new dishwasher installation, labor costs $175–$525, with an average of $350 for work done. If you’ve never owned a dishwasher, or you’re in a home that doesn’t have one, installation can become more involved. First, you must pay for wiring (including a circuit breaker), pipes that must be installed, and sometimes even more space garnered from your present counter and cabinets. The number of professionals you need will affect the cost.

  • Carpenter: $74/hour to customize or build any cabinet space and countertops with backsplash. Hours depend on the amount of customization needed.
  • Plumber: $86/hour to connect water supply and drainage pipes or install new ones. Two to 2.5 hours. Plumbing supplies $5–$23 each
  • Electrician: $80/hour for additional wiring and installing high-voltage outlets. Two hours.

Types of Dishwashers

The types of dishwashers available are numerous: built-in, portable, countertop, front-control, top-control, freestanding, and more. We’ll examine a few, with prices from The Home Depot:

  • Built-in dishwasher ($290–$2,890) – Built-ins are the most common dishwasher and are widely available for purchase. These dishwashers provide many benefits and features. One popular feature is the fact they are quiet. This occurs because they are surrounded by cabinets, which helps muffle sounds. This appliance is usually available when purchasing a home, so you don’t have to be concerned about finding a spot for it. It is permanently connected to plumbing, which, unlike portable dishwashers, will not have to be disconnected to use for something else.
  • Countertop or compact dishwasher ($135–$375) – If you move into an older home, you sometimes find that space is at a premium. Countertop dishwashers act like a portable dishwasher and can attach to your sink pipes with a converter. This type of dishwasher is able to hold about four place settings. This model is ideal for small families and people on tight budgets.
  • Portable dishwasher ($350–$630) – Portable dishwashers are ideal for those who cannot afford to attach the plumbing necessary when having a built-in dishwasher installed. There a few plusses when choosing this option: they are easily movable and offer more countertop space—a smart decision, especially if you aren’t running many loads. People in apartments, as well as small families, often choose this kind of dishwasher.
  • Freestanding dishwasher ($415–$1,950) – The beauty of this type of dishwasher is that you don’t need any cabinet space for it—you can park it at the end of the kitchen counter. It can be installed in small kitchens too.
  • Under sink dishwasher ($445–$810) – These space-saving dishwashers made by GE require a special shallow sink and measure 24 inches wide by 34 inches high by 24 inches deep.

Best Dishwasher Brands

The average homeowner can find a good dishwasher in the $595–$895 range. These dishwashers perform very well and get the job done. However, there are now high-end dishwashers, at $1,500 up, that are sleek, offer Wi-Fi connectivity, have controls across the door which are concealed when the door is closed and have LED lights for when the dishwasher is opened. These machines also offer different wash cycles that are specifically for heavily soiled items.

The Wi-Fi connectivity is interesting because from your smartphone, you are able to receive updates regarding the wash cycle, or you can even control your machine remotely. With one high-end dishwasher, you can even reorder dishwasher detergent using your smartphone and Alexa. Another model issues warnings if your dishwasher is leaking.

Best Dishwasher Brands Under $500

  • Whirlpool $330
  • Kenmore $475
  • Amana $440

The three popular dishwasher brands all come in below $500. Most of these rated well in how they clean dishes and glassware. To top it all, these dishwasher models are energy-efficient. To be fair, all of these dishwashers come with only basic features. While Kenmore (Sears brand) is mentioned as one of the three most popular brands, be aware that Sears has filed for bankruptcy protection.

"Be aware that there is a chance that the Kenmore warranty, or any warranty from Sears itself, won't be honored if Sears liquidates without another owner taking over, . . . Most people never have to make a warranty claim. And don't buy a service contract, which is just a very expensive form of insurance.”[1]

Top-rated Dishwashers

  • Bosch Ascenta $ 630
  • Bosch Ascenta $ 510
  • Bosch 300 DLX Series $ 800

These dishwashers provide great cleaning, and they are quieter than the more basic models. They also have more convenient features, including adjustable racks, movable silverware baskets, a soil sensor, and a stainless-steel tub. In addition, you can find more finishes to suit your taste, including black, slate, stainless, bisque, and others.

Best High-end Dishwashers

  • Bosch Benchmark $1,600
  • Thermador $1,800
  • Thermador $2,300

These high-end dishwashers provide a sleek look with enhanced features, such as Wi-Fi connectivity, more cycles, concealed controls, and special wash zones for heavily soiled items. While most high-end dishwashers perform well, be aware that some of them don’t measure up to the more reliable, popular brands (under $500) and the good dishwashers (priced from $600–$900).

Additional Dishwasher Cost Considerations

As mentioned above, additional expenses come into play when installing your new dishwasher.

  • Removing and disposing of the old dishwasher - About $60 to remove it and a custom price from the plumber to dispose of it. Some charities will pick up your old dishwasher if it’s still in good working order. If you’re getting the hardware store to deliver your new dishwasher, they will often haul and dispose of your old one at the same time for a minimal fee of $20.
  • Dishwasher installation problems - Some of the possible risks of a poor installation are:
    • An electrical short, which could cause a fire and substantial damage.
    • Kitchen flooding, and possibly other rooms as well.
    • If the dishwasher is improperly anchored, knocking, bumping, or other noises could occur.
  • Building codes - When installing a dishwasher into a new kitchen, the installation will also possibly need to include:
    • Bringing any of the HVAC, electrical, or plumbing systems into compliance with current building codes
    • Costs for testing of hazardous materials such as lead and asbestos
    • Required permits or inspection fees for electrical and plumbing work.
  • Equipment delivery to and from the job site - Home Depot and Lowe’s charge a $59 delivery fee which applies to any major appliance purchases below $396. Appliances more than $396 get free delivery.

Frequently Asked Questions

Is it hard to install a dishwasher?

As long as you have the right tools and supplies, and you know how to turn power and water supplies off at the mains boxes, installation is quite straightforward. The downside is in making sure you’ve attached all hoses, pipes, and connectors securely and according to the manufacturer’s instructions. If you haven’t, you could end up flooding your kitchen, having electrical shorts, and voided your warranty.

What’s a dishwasher air gap?

A dishwasher air gap is a device that is installed above the sink or just below it connecting the dishwasher drain hose to the house’s drainage system. It prevents any backflow of dirty dishwater water back into the dishwasher. All plumbing codes require backflow prevention.

What are the average dishwasher dimensions and dishwasher sizes?

The standard size of a built-in dishwasher is approximately 24 inches wide by 35 inches high by 24 inches deep. The average size of a portable dishwasher is 18 inches wide by 36 to 37 inches high by 24 inches deep.

How much water does a dishwasher use?

“The average dishwasher uses 6 gallons of water per cycle; the average Energy Star-rated dishwasher uses 4 gallons per cycle, and their energy use ranges from 1.59 kWh per load down to 0.87 kWh per load.”[3]

Who invented the dishwasher?

The first commercial dishwasher was invented in 1886 by a woman—Josephine Cochrane. The first model was designed in a shed in the back of her house in Shelbyville, Illinois. Instead of using scrubbers to clean the dishes, she used water pressure, which was a first. Her dishwasher had specific racks which held plates, saucers, and cups. A motor turned the wheel, and hot, soapy water squirted from the boiler and drenched the dishes. Eventually, she patented the design, and the first commercial dishwasher went into production. In the 1950s, the dishwasher became a well-known household product, and people have depended on it ever since.
