Dishwasher Installation Cost

Dishwasher Installation Cost in Phoenix

So you're tired of hand-washing dishes. Smart move. A new dishwasher makes life easier, and if you've already picked one out, the next question is: how much is this going to cost to install? I'll give you the straight answer.

In the Phoenix East Valley, a standard dishwasher installation runs between $400 and $800. That's for a straightforward swap where you're replacing an existing unit or installing one into prepared cabinetry. If your situation is more complicated—we'll get to that in a minute—you could be looking at $1,200 or more.

What Affects Your Installation Cost

A few things determine where you land in that price range. First, is this replacing an old dishwasher or a new install?

If you're pulling out an existing unit, removal adds a little time but not much. We disconnect the water supply, unscrew the mounting brackets, and haul it away. Takes maybe 30 minutes. We charge a removal fee of about $75 to $150 depending on what we're dealing with.

New construction is different. If there's no dishwasher rough-in already done, you're looking at running supply lines, a drain line, and electrical. That means opening cabinet walls, running copper tubing, fitting it all correctly, and making sure it drains properly. This isn't a two-hour job anymore. It's closer to five or six hours, sometimes more if we hit surprises.

Speaking of surprises: plumbing. This is where costs jump. If your water supply lines are in bad shape—old galvanized pipe that's corroded, leaks under the sink, or the shutoff valve is seized—we need to fix that first. I've seen supply lines fail within weeks of an installation because nobody dealt with the existing problems. We replace those with new quarter-inch copper or PEX. It costs money, but it beats a flooded cabinet later.

Cabinet modifications matter too. Some dishwashers are wider or taller than what came before. If your cabinetry needs cutting, shaving, or adjustment, that takes time. Usually not a big deal, but on occasion we've had to get creative with trim pieces or filler strips.

Then there's the drain. Most kitchens have a drain already stubbed in. We connect to it. But if the cabinet layout changed or the previous install was sloppy, we might need to reroute the drain line or install a new one. A clogged or improperly pitched drain line is invisible until your dishwasher starts backing up.

Electrical can also add cost. Newer dishwashers sometimes need 120V dedicated circuits. If that doesn't exist, we either run one or tap into existing power carefully. This isn't a DIY situation—you want a licensed electrician for this part.

What's Included When You Hire Us

Here's what you're paying for:

• Removal of the old unit (if applicable)
• Inspection of supply, drain, and electrical lines
• Connection to water supply with proper shutoff valve
• Drain line installation and pitch verification
• Electrical connection (or coordination with an electrician)
• Mounting and securing the unit inside the cabinet
• Testing to make sure everything works before we leave
• Haul-away of the old dishwasher

We don't typically include the cost of the dishwasher itself or any cabinetry modifications beyond basic cuts and fits. If you need a plumber to upgrade your supply lines or an electrician to add circuits, those are separate line items.

DIY vs. Hiring a Pro

Can you install a dishwasher yourself? Sure. I see it happen. Some people do fine with it.

Should you? That depends on your comfort level and what "fine" means to you. A loose connection on the water supply can leak slowly for months before you notice the damage. A drain line pitched wrong means water sits in the line and gets gross. Electrical mistakes can be unsafe.

If you're handy, have done plumbing before, and you're replacing an existing unit into the exact same space, you might pull it off. Rent the right tools, watch some videos, take your time. The savings might be $300 to $400.

If there's any uncertainty—about plumbing, electrical, cabinetry, or water supply—just call a pro. It's not worth the aggravation or the risk. I've had people call me to fix a DIY install that went sideways. The bill ends up being higher than if they'd hired me from the start.

Common Questions

How long does installation take?

Straight replacement, no complications: 2 to 3 hours. New construction or significant modifications: 5 to 7 hours. We're not rushing, but we're also not dragging it out.

Do I need to be home during installation?

Yes. We need access to the kitchen, under the sink, and ideally the main water shutoff. Plus, you should be here to ask questions and watch us test everything before we leave.

What if something goes wrong after installation?

We warranty our work for 30 days. If something fails because of our installation, we fix it. Manufacturer defects on the unit itself are between you and the dishwasher company.
