How much does dishwasher installation cost? If you’re asking this question, you’re probably standing in your kitchen staring at a brand-new dishwasher box, wondering if you should tackle installation yourself or call a professional. Or maybe you’re still shopping and trying to budget for the total project, not just the appliance.
We’ve installed hundreds of dishwashers in San Diego County homes, and we hear this question almost every time. The answer isn’t as simple as a single number because every installation is different. But we can give you a clear picture of what you’ll pay and why.
This guide breaks down dishwasher installation cost in plain language. You’ll learn what affects the price, what extra charges to watch for, and when professional installation is absolutely worth the money.
Understanding Basic Dishwasher Installation Cost
For a standard replacement installation where you’re swapping an old dishwasher for a new one, dishwasher installation cost typically runs between $150 and $300 for labor. This assumes your water lines, drain connections, and electrical outlet are already in place and working correctly.
This price covers removing your old dishwasher, connecting the new one to existing hookups, leveling it properly, and testing everything to make sure it works. Most professionals can finish a basic replacement in about two hours.
But that’s just for the simplest scenario. Many dishwasher installations cost more because they need extra work. Let’s look at what drives these costs up.
When You Don’t Have Existing Hookups
The dishwasher installation cost jumps significantly if you’re adding a dishwasher where one never existed before. You’ll need a plumber to run a water supply line from your sink to the dishwasher location. You’ll also need a drain connection, usually to your sink drain or garbage disposal.
This kind of work typically adds $300 to $600 to your dishwasher installation cost. In some cases, especially if your kitchen layout is complicated or you need to run lines through multiple walls, it can cost even more.
You also need an electrical connection. Most dishwashers require a dedicated 120-volt circuit. If you don’t have an outlet under your sink or nearby, you’ll need an electrician to install one. Expect to pay another $150 to $350 for this electrical work.
So for a true first-time installation with no existing connections, your total dishwasher installation cost might range from $600 to $1,300 just for labor, before you even buy the appliance.
What Your Location Does to Pricing
Dishwasher installation cost varies quite a bit depending on where you live. In San Diego County, labor rates tend to run higher than in rural areas but lower than in places like San Francisco or Los Angeles.
Urban and suburban areas have higher costs because of increased demand for skilled tradespeople. But they also have more competition, which can work in your favor when you shop around for quotes.
Your home’s location within your house also matters. Installing a dishwasher on the main floor is straightforward. But if you want one in a second-floor kitchenette or basement wet bar, the dishwasher installation cost goes up. The installer needs to carry the heavy appliance up or down stairs, which often adds $50 to $100 to the bill.
Accessibility plays a role too. If your kitchen is cramped or your dishwasher sits in a tight spot surrounded by cabinets, installation takes longer and costs more. We’ve worked in some San Diego homes where getting the old dishwasher out required removing cabinet doors and trim pieces.
Type and Size of Dishwasher
Most dishwashers are standard built-in models that fit in a 24-inch-wide space under your counter. These have the most straightforward installation and the lowest dishwasher installation cost.
Compact 18-inch dishwashers sometimes cost a bit more to install because they might need custom connections or modifications to fit properly. Double-drawer dishwashers also increase labor costs because they’re heavier and more complex to install.
Portable dishwashers are the cheapest to set up. They just roll into place and connect to your kitchen faucet. But they’re not permanent installations, so most people don’t hire professionals for these.
Panel-ready dishwashers designed to match your cabinets add another layer of expense. Installing a custom panel typically costs an extra $150 to $300 because it requires precise measurement and careful mounting to match your cabinetry.
Old Dishwasher Removal and Disposal
Don’t forget about getting rid of your old dishwasher. Many installers include removal in their base dishwasher installation cost, but some charge separately for this service.
Removal and disposal typically add $20 to $100 to your bill if not included. The installer needs to disconnect the old unit, haul it out, and dispose of it properly. Most take old appliances to recycling centers rather than landfills.
If you want to save this cost, you can remove the old dishwasher yourself before the installer arrives. Just make sure you turn off the water supply and disconnect everything safely. Or you can list it for free on Craigslist or Facebook Marketplace and let someone else haul it away.
Code Compliance and Upgrades
Sometimes installation reveals that your existing setup doesn’t meet current code requirements. This can increase your dishwasher installation cost unexpectedly.
For example, many areas now require an air gap device to prevent dirty water from backing up into your dishwasher. If you don’t have one, the installer needs to drill a hole in your sink or countertop and install it. This typically adds $30 to $75 to the job.
Old plumbing might need updating too. If your shut-off valves are corroded or leaking, they should be replaced before connecting a new dishwasher. If your drain connection doesn’t have a proper high loop or air gap, code requires fixing it.
These necessary upgrades can add $100 to $300 to your dishwasher installation cost. But they’re not optional if you want your installation to pass inspection and work safely. Our plumbing repair experts make sure all installations meet current San Diego building codes.
Parts and Materials You Might Need
Many people are surprised to learn that dishwashers don’t always come with everything needed for installation. Missing parts can add to your dishwasher installation cost.
Most dishwashers need a separate power cord, which costs $15 to $30. You might also need a new water supply line, which runs $10 to $25. A drain hose costs $15 to $40 if the one included isn’t long enough or doesn’t fit your setup.
Mounting brackets, compression fittings, wire connectors, and other small hardware pieces can add another $20 to $50 to your total. Professional installers usually bring these items and include them in their quote, but it’s worth asking upfront what’s covered.
Professional Installation Versus DIY
Should you pay the dishwasher installation cost or save money by doing it yourself? This depends on your skills and the complexity of your specific installation.
If you’re replacing an existing dishwasher and you have experience with basic plumbing and electrical work, DIY installation might save you the $150 to $300 labor cost. You’ll need basic tools and a couple of hours.
But consider the risks. A poorly connected water line can leak and cause serious water damage. Incorrect electrical connections create fire hazards. If something goes wrong, the cost to fix the problem often exceeds what you would have paid for professional installation in the first place.
Most dishwasher manufacturers warn that DIY installation can void your warranty if done incorrectly. This is a big deal if your new appliance develops problems in the first year.
For first-time installations that require running new plumbing and electrical lines, professional installation isn’t just recommended—it’s essential. You need licensed professionals for this work. In many jurisdictions, you can’t even get permits for plumbing and electrical work without a license.
The peace of mind that comes with professional installation is worth the dishwasher installation cost for most homeowners. You know it’s done right, it’s up to code, and if anything goes wrong, the installer’s insurance covers it.
Specialty Situations That Increase Costs
Some installations cost more because of unique circumstances. Understanding these situations helps you budget accurate dishwasher installation cost for your project.
If you need to modify cabinets to fit your new dishwasher, expect to pay extra. Maybe the opening is slightly too small, or the new dishwasher is a different size than your old one. Cabinet modifications typically cost $100 to $400 depending on complexity.
Installing a dishwasher in a kitchen island is more complex than under a regular counter. You might need extended water and drain lines, and the dishwasher needs to be properly vented so it works correctly. This can add $200 to $500 to your dishwasher installation cost.
If your kitchen has a granite or quartz countertop, extra care is required during installation. These materials are fragile at mounting points, and cracking them costs thousands to repair. Installers charge more for working with high-end countertops because of this risk.
Relocating a dishwasher to a different spot in your kitchen is basically a full new installation. You’ll pay to run new supply and drain lines, install a new electrical connection, and possibly modify cabinets at both the old and new locations. Total cost can easily hit $1,000 to $1,500 or more.
How to Get Accurate Quotes
To get realistic dishwasher installation cost estimates for your project, provide installers with complete information upfront.
Tell them whether you’re replacing an existing dishwasher or installing one for the first time. Mention if you have water, drain, and electrical connections already in place. Let them know if you’re on a second floor or have any accessibility challenges.
Provide the make and model of your new dishwasher if you’ve already purchased it. Different brands have slightly different installation requirements. Panel-ready models need extra information about your cabinet specifications.
Ask what’s included in the quote. Does it cover removal of your old dishwasher? Are all parts and materials included, or are those extra? Will they haul away packaging and the old unit?
Get quotes from at least two or three different installers. Prices can vary significantly. But don’t automatically choose the cheapest option. Check reviews, verify licenses and insurance, and make sure you’re comparing similar services.
According to the Environmental Protection Agency’s ENERGY STAR program, a properly installed dishwasher not only works better but also saves water and energy. Poor installation can reduce efficiency and cost you more on utility bills over time.
Making Installation Part of Your Budget
When budgeting for a new dishwasher, don’t forget to account for dishwasher installation cost as a separate line item. Many people focus only on the appliance price and then get surprised by installation expenses.
A $500 dishwasher with $200 installation costs $700 total. That’s fine if you budgeted for it. But if you only set aside $500, you’re short by $200.
Some retailers offer bundled pricing that includes delivery and installation. These deals can save money, but read the fine print. The “free installation” might only cover basic hookup to existing connections. Any extra work costs more.
If your dishwasher installation cost seems high, ask about payment options. Many plumbing companies offer financing for larger jobs. This lets you spread the cost over several months instead of paying everything upfront.
When to Call a Professional
Understanding dishwasher installation cost helps you make smart decisions, but knowing when to call a professional is just as important.
Always hire a licensed plumber if you’re installing a dishwasher for the first time in a location without existing connections. This work requires permits in most areas, and only licensed professionals can pull them.
Call a pro if your installation needs any of the following: new water supply lines, new drain connections, electrical circuit installation, cabinet modifications, or work with high-end countertops.
Even for a simple replacement, professional installation makes sense if you’re not comfortable with plumbing and electrical work. The dishwasher installation cost is worth it for the peace of mind and warranty protection.
