How Much Does a Dishwasher Installation Cost?

An automatic dishwasher can be a great time saver in the kitchen, adding convenience to your clean-up tasks. In addition to the model of appliance you choose, a few factors will contribute to the price of your installation. If you have never had a dishwasher in your kitchen before, give special consideration to the location and connections for your new appliance.

Average Prices

Installing a New Dishwasher

The cost for professional installation of your dishwasher will be affected by the location and condition of the connection site. Current rates for a standard dishwasher installation range from $119 to $221 in the U.S. and depend largely on whether the necessary electrical and plumbing connections are in place. Additionally, if your kitchen has never sported a dishwasher before, modifications to your cabinetry may be made to make space for the new appliance. Any work needed to fit and connect the dishwasher will add to the overall cost of your installation and may require the services of a plumber, electrician, or carpenter. Be sure to ask your installer if he will coordinate additional prep work, or if you will need to hire the appropriate contractors.


Replacing a Dishwasher

If you are replacing an existing dishwasher with a new one, it is likely that no modifications will be required to fit the new unit. National prices for the installation of a replacement dishwasher are between $106 and $196 currently. Repairs or upgrades to your plumbing or wiring that are needed to accommodate your new appliance will add to the cost of your installation, and removal and disposal of your old unit may come at an extra charge. Be sure to discuss the removal of your old dishwasher when you schedule your installation so you will be aware of any fees or preparations that will be required.


Wiring for Your Dishwasher

Since your dishwasher requires an electrical connection, new wiring may be needed. If your kitchen has never been prepared for a dishwasher, an electrician will need to install wiring from the installation site to your electrical panel. The distance from the site to the panel, the layout of your home and the condition of your current wiring will determine the complexity and cost of labor and materials for the electrical work. National rates for dishwasher installations complete with wiring are between $227 and $354.


Plumbing for Your Dishwasher

Plumbing connections for dishwashers are generally made within the kitchen and tie into the supply and drain lines of your sink. Prices for installing a dishwasher with new plumbing connections typically range from $236 to $383 and depend primarily on the condition of your current plumbing and the distance between the existing lines and the dishwasher’s location. A plumber can make any needed repairs or modifications to prepare for your dishwasher, but if the appliance is not installed adjacent to your sink, extra costs will be incurred to run plumbing through, under, or behind your cabinetry.


Installation Locations

Since dishwashers are typically placed in kitchens and near existing plumbing, installations are relatively consistent. However, installing a new unit on an upper level of your home or building may pose challenges that add to the cost. In addition to possible increases in materials and time for carpentry, wiring or plumbing, the added burden of moving your dishwasher to an upper level may come at a premium. Also, your installer may recommend adding a drip pan under your new appliance to prevent damage from any leaks that may occur under the unit. These added considerations contribute to the cost of your project, which averages $247 for a third-floor installation compared to $163 for a first-floor job.


Your Dishwasher Installation

The cost of installing a dishwasher will depend on a few different variables. The cost of labor in your area, whether or not you already have a dishwasher in that location, and how accessible the area is (either from an attic or a basement), will make a difference when it comes to how much you'll pay. For example, if the dishwasher is being installed in a new location, then you will have to have water supply lines run, a drain line connected to the house's main waste line, a new electrical line run from the service panel (with a new breaker), and a new outlet installed under the sink. On the other hand, if you're just replacing an existing dishwasher, then the old one just has to be unplugged and disconnected and the new one will have to be plugged in and connected. The cost of labor varies from place to place. A licensed plumber will charge you anywhere from $75 to $150 an hour.


Plan Ahead for Your Install

Understanding the factors that affect your dishwasher installation can help you plan and budget for the project. Discuss with your installer the location for your new appliance, whether the necessary hook-ups are prepared, and if you need to dispose of an old unit. A number of details help determine the total cost of your installation, and planning ahead will help you avoid expensive surprises.
