What’s the Average Cost to Install a Dishwasher?
If you’re trying to budget for a dishwasher installation, it’s easy to get overwhelmed. Online estimates vary, and it’s not always clear what is included. The truth is that dishwasher installation costs depend on a few key factors – and knowing what to expect up front can help you avoid frustration and surprise charges.
On average, professional dishwasher installation without purchasing a new unit typically costs between $500 and $1,200. If you’re also buying the dishwasher unit, your total cost – including both the installation and the appliance – can range from $800 to over $2,000, depending on the system’s features and the installation details.
Yes, professional installation costs more than a DIY attempt, but it brings real peace of mind. You won’t have to second-guess water line connections, worry about leaks, or risk damage to your kitchen. Not to mention you could risk damaging your new dishwasher itself. With a licensed plumber, you’ll get it done right the first time – no worries, no stress.

Dishwasher Installation Costs: What to Expect
If you’ve already purchased your dishwasher and just need it installed, you’re in a good place – but it’s essential to understand what “just installation” really entails. For homes where a previous dishwasher existed and all the plumbing and electrical connections are still in good shape, the process is fairly straightforward.
At first glance, paying between $500 and $1,200 for installation might seem steep – especially if you’ve just spent hundreds on the appliance itself. But what you consider what’s included, the value becomes clear.
A professional installation covers disconnecting the old unit, preparing the space, securing the new dishwasher to cabinetry, connecting all water, drain, and electrical lines, and safely running a full test cycle to ensure everything works safely and correctly.
It also means there’s no guesswork, no tools needed on your part, and no water leaks behind your cabinets. Even small surprises – like a stuck shutoff valve or an outdated connection – can turn a DIY job into a mistake that requires an expensive repair. With a professional, you get the job done right the first time – and that’s some real peace of mind.
Cost of Installing a New Dishwasher – Plus Buying the Unit
If you haven’t purchased a dishwasher yet, you’re looking at two cost components: the unit itself and the installation. Most dishwashers range from $300 to $1,200, depending on brand, capacity, and features. High-end models – such as ultra-quiet operation, built-in sensors, or smart connectivity – can run $1,500 or more.
Once you have the unit, professional dishwasher installation typically adds $500 to $1,200 to the overall cost, unless additional work is needed. So in total, homeowners should expect to pay anywhere from $800 to $2,000 or more.
If you’re looking to tighten your budget, you’ve probably already thought about installing the system yourself. And if you have experience working with plumbing and electrical systems, you may be able to do so successfully. But be aware that small oversights can lead to damage and hazards down the road. It’s your call, so be sure to become educated on how to install your dishwasher.
What Impacts Dishwasher Installation Costs?
No two homes are exactly alike, and that’s especially true when it comes to plumbing and electrical systems. Several key factors can influence the final price of your dishwasher installation service.
One of the biggest factors is your kitchen’s layout and age. In older homes, plumbing and electrical connections may need updates to meet today’s safety codes. Installing a dishwasher for the first time – where no unit previously existed – can also drive costs up because new drain lines, shutoff valves, and outlets must be added from scratch.
Even a replacement installation can become more involved if cabinets need adjusting, flooring obstructs the unit, or water lines are corroded. Knowing these factors in advance helps set realistic expectations and avoid last-minute surprises.
Installation costs can also vary based on where you live. Labor rates tend to be higher in urban and suburban areas, compared to rural locations, due to increased demand.
Missing Parts or Upgrades Can Add to the Final Bill
Many people are surprised to learn that new dishwashers often don’t come with all the parts needed for installation. Essentials like the drain hose, power cord, water supply line, or mounting brackets may need to be purchased separately – adding anywhere from $30 to over $100+ to the task, depending on what’s missing.
Sometimes, the installation reveals deeper issues – like aging plumbing, stuck valves, or outdated outlets. Bringing your setup up to current code can add $100 – $300, however these modifications are essential to the safety of your home.
Choosing a professional for these services isn’t just about convenience – it’s about making sure the job is done right, safely, and preventing future headaches. A qualified installer can asses your setup ahead of time, explain any issues, and give you a clear plan forward.

5 Dishwasher Installation FAQs
1. How Much Does It Cost To Install A Dishwasher?

2. Can I Install A Dishwasher Myself?

Hiring a licensed professional helps ensure the job is done safely, correctly, and up to local standards.
3. What’s Included in a Professional Dishwasher Installation?
A typical installation may include removing the old unit (if needed), connecting water, drain, and electrical lines, securing the unit in place, and running a test cycle to check for leaks and proper function. It may also include adjustments or upgrades if parts are missing or not up to code.
4. Do I Need a Plumber or an Electrician To Install a Dishwasher?
In most cases, a licensed plumber can handle the full installation, including the water supply, drain line, and electrical connection (especially if the existing setup is already in place). If significant electrical changes are needed – like installing a new outlet – an electrician may be needed. At Mattioni, our licensed team handles all typical installation needs.
