In college, everyone had that roommate who’d pile up dishes in the sink. In adulthood, you might be that roommate. There’s no shame in it. Life is busy, but if the plates are piling up, it may be a signal that it’s time to get a new dishwasher. The average homeowner spends $970 to purchase and install a new dishwasher—but for many, the price is well worth never having to wash a dish by hand again.

Dishwashers don’t just make your life easier. They can actually reduce water consumption. Studies have shown that dishwashers generally use less water than hand-washing. Whether you’re looking to install a brand new unit or replace your old dishwasher, cost is a major factor. Don’t let a bad contractor do you dirty when you’re trying to keep your kitchen clean. Get familiar with the expected costs ahead of the job.

How Much Does It Cost to Install a Dishwasher?

The average cost to purchase and install a dishwasher is $970. The installation alone usually runs homeowners $110 to $270. The overall costs can drastically vary based on the type of dishwasher you choose and the project specifications. 

Replacing an old dishwasher generally costs less than installing a brand new unit because you won’t have to retrofit your kitchen. Costs can hit upwards of $3,500 for a complicated job with a high-end appliance, but homeowners can pay as little as $370 for a basic dishwasher installation.

How Much Does It Cost to Install a Dishwasher by Type?

Most homeowners pay $110 to $270 to have a professional install their dishwasher, but extra plumbing work can skyrocket that figure. For example, some kitchens don’t have the plumbing hookup, so they’ll need to get one installed. This could cost an additional $600 to $1600. Options like a portable or countertop dishwasher (which hooks up to your sink and isn’t retrofitted into kitchen cabinets) will help you avoid labor costs. Most homeowners install these on their own.

If you don’t already have a dishwasher waiting for you in storage, you’ll have to buy one before you can install it. This adds a significant expense, which varies based on the type of dishwasher. Most dishwashers run between $400 and $700, but higher end models cost more.

Built-In Dishwasher

  • Units cost $300–$1,000

  • The most common type of dishwasher

  • 24-inch width (though there are 18-inch slimline options)

  • Two racks

  • Requires professional installation

Drawer Dishwasher

  • Units cost $270–$1,380

  • One rack

  • Ideal for smaller kitchens

  • Easily fits into cabinets

  • Good for homeowners who don’t use a lot of dishes

  • Requires professional installation

Countertop Dishwasher Installation

  • Units cost $200–$400

  • Sits on counter, similarly to a microwave

  • No plumbing required; attaches right onto your sink

  • Good solution for renters/apartment dwellers who don’t have a built-in dishwasher

  • Budget friendly but holds fewer dishes than other options

Portable Dishwashers

  • Units cost $390–$690

  • The same size as a built-in dishwasher

  • Can be easily stored in a utility closet

  • Attaches to kitchen sink; no extra plumbing required

  • Doubles as a butcher block or kitchen island

  • Portable dishwashers are a budget-friendly solution for homeowners who don’t have existing plumbing to support a built-in dishwasher

How Much Does It Cost to Install a Dishwasher Yourself?

Many homeowners opt to install portable or countertop dishwashers on their own because they don’t require plumbing hookups (though, be warned: dishwashers can weigh 50 to 150 lbs., so you may need a friend to help). In this case, you’ll just have to pay for the appliance. 

Installing a built-in or drawer dishwasher requires plumbing knowledge, and a mistake can lead to flooding or electrical issues that cost way more than the average cost of labor. You might save a couple hundred bucks on a plumber but create a problem that costs thousands.This job is best left to a local plumbing professional (and sometimes, even a permit is required).

Most of the time, it costs between $110 to $270 for a professional to install a dishwasher, and an additional $400 to $700 to buy the actual appliance. The total cost of the job is influenced by:

It’s usually easier to replace an old dishwasher than to install a brand new dishwasher. In fact, a plumber may swap out your old unit for as little as $70. It takes more time (read: more money) to carve out a brand new space. A new built-in or drawer dishwasher could involve serious kitchen and plumbing renovations.

Retrofitting Your Kitchen

If your kitchen has to be retrofitted, you’re looking at a wealth of additional costs—like removing and replacing kitchen cabinets, adding electrical outlets, or creating a brand new kitchen island to house your appliance. The costs might look like:

Opting for a portable dishwasher can eliminate many of these costs (so long as you have space to store it when it’s not in use).

Installing New Plumbing

If you’re installing a brand new dishwasher, you may need a new plumbing hookup. Installing new plumbing pipes costs between $600 to $1,600 per fixture, but you can save 20% to 40% by opting for PEX or CPVC pipes rather than copper. Though this is an expensive upfront cost, it can add value to your home.

Dishwasher Installation Cost Breakdown

Dishwasher installation costs can be broken down into three parts.

Materials

This includes the cost of your dishwasher, plus extra materials like dishwasher connections, a pipe joint compound, and protective covers for your floors and cabinets. It may also include parts for additional renovations like new countertops or cabinets.

Labor

The average homeowner pays $190 in labor-related dishwasher installation costs. Labor can cost as little as $70 or as much as $500. The average dishwasher replacement takes a plumber about three hours (one hour to remove the old unit, and two hours to install the new one). As the job gets more complicated, labor costs rise.

Permits

Your plumber may need a permit to install a dishwasher depending on the scope of the job (especially if new plumbing or electrical work is involved). These costs are passed onto the homeowner.

FAQ About Dishwasher Installation

What is the average lifespan of a dishwasher?

The average dishwasher lasts between 9 and 10 years. With great maintenance and care, your dishwasher could last up to 12 years. It all depends on how often you use it and how well you’ve maintained it.

What type of dishwasher is best for my home?

Built-in dishwashers are the standard, but if you have a smaller kitchen and the available plumbing, you may want to opt for a drawer dishwasher. You can stack drawers to increase the dishwashing capability (as long as you have the space).

If you don’t have a plumbing hookup, you can save renovation costs by opting for a portable or countertop dishwasher. Countertop dishwashers are particularly good for renters who live in small spaces.

Should I fix my broken dishwasher or replace it?

The average dishwasher repair costs $160 to $300. Since a basic dishwasher only costs a couple hundred more, you may want to replace your broken dishwasher if it’s nearing the end of its lifespan. A simple fix like replacing a pump or motor might cost less, and in that case, a repair can prolong the life of your appliance.
