Dishwasher Installation Cost

Dishwasher Installation Cost

Installing a dishwasher can be a quick swap—or a bigger plumbing and electrical project—depending on whether you’re replacing an existing unit or adding a dishwasher for the first time. The typical cost of a dishwasher plus installation ranges from about $1,000 to $1,500 depending on the brand you choose and how straightforward your install is. This guide breaks down the dishwasher installation cost, what’s typically included, and when you may want a plumber to install dishwasher connections so everything drains correctly and stays leak-free.

Average Dishwasher Installation Cost (Quick Price Ranges)

Here are realistic “budgeting” ranges homeowners see most often:

• All-in cost (dishwasher + installation): Typically ranges from $1,000–$1,500 (average around $1,200) when the appliance cost is included. If you choose a high-end dishwasher brand, your all-in cost could be higher.
• Installation-only (labor/standard hookup): Excluding the cost of the dishwasher, installation is often under $500 for a straightforward replacement, but it climbs quickly if you need plumbing/electrical/cabinet work.

Dishwasher Replacement Installation (Swap-Out)

If you already have a dishwasher in the spot your new dishwasher will go, and you’re swapping like-for-like (existing plumbing + power are usable), this is usually the lowest-cost scenario.

• Typical labor-only replacement: Typically, labor costs range from $200–$500.
• All-in project total: Like we stated above, this will likely be in the $1,000–$1,500 range depending on appliance cost and add-ons.

Here’s what’s generally happening in a swap out: your plumber will remove your old dishwasher, connect water/drain/power to your new unit, level the dishwasher, secure it, and then run a test cycle to ensure everything is working correctly.

First-Time Dishwasher Installation

Installing a dishwasher where one doesn’t currently exist? This is common in kitchen remodels, and costs are higher and more variable. A brand-new dishwasher installation can cost between $1,200 and $3,200 total. That wider, higher range is because you may need:

• a new shutoff valve and supply line.
• a new drain tie-in (and possibly code-driven changes).
• electrical outlet/circuit work.
• cabinetry modifications.

Do I Need a Plumber to Install a Dishwasher?

Yes, a plumber is the right professional to install a dishwasher. You may be able to DIY your dishwasher replacement if you are doing a simple swap and have a reasonable amount of experience. However, you’re more likely to want a plumber if you need:

• New water line or shutoff valve.
• Drain modifications or rerouting.
• Dishwasher air gap installation.
• Any leak/corrosion remediation under the sink.

If you need a new outlet/circuit or you’re changing from plug-in to hardwired, electrical work may be required. Your plumber may able to handle this themself or may recommend hiring an electrician.

What’s Included in Dishwasher Installation (and What’s Not)

What’s Usually Included

For many standard installs, you’ll typically get:

• Connection to existing water supply and drain, including basic dishwasher drain hose installation.
• Leveling/fastening the unit.
• A test cycle and leak check.

Common Exclusions (Often an Added Cost)

These frequently add to price because they add time, parts, or a second trade:

• New electrical outlet/circuit (electrician).
• Cabinet modifications or tricky fit issues.
• Replacing a leaking/corroded shutoff valve.
• Haul-away/disposal.
• Permits/inspections (where required).

Cost Factors That Change Dishwasher Installation Price

Replacement vs. First-Time Install

Swap-outs tend to be cheaper because the hookups already exist. First-time installs often require new plumbing and/or electrical work. This is covered in more detail further up this page!

Plumbing Condition and Access

Old valves, tight cabinets, and corroded fittings increase labor time and parts, all of which raises the total.

Drain Setup and Local Requirements

Drain configuration matters for performance and, in some areas, code. If your setup needs dishwasher air gap installation (or correction of drain routing), expect added parts + labor.

Electrical Needs

Plug-in vs. hardwired and whether a dedicated circuit is needed can substantially change the scope of installation work needed.

Add-On Costs You Might Need

Dishwasher Air Gap Installation

A dishwasher air gap is a fitting that connects your sink’s drain to your dishwasher. If an air gap is required in your area (or recommended for your setup), this add-on is often relatively quick, but it still adds parts and labor. You can expect an air gap installation to add about $100 to your project total.

Drain Hose Replacement

Sometimes the installer can reuse the existing hose. However, if the hose is brittle, kinked, has odor or draining issues, or already needs to be rerouted, you may need to replace it.

• Drain hose part cost: This inexpensive part can often be replaced for around $15.
• Labor/service: Replacing the drain hose will typically not add any additional labor costs. If you are replacing your dishwasher drain hose outside of a replacement, it may cost $75 to $150.

Water Supply Line, Shutoff Valve, and Fittings

If the shutoff valve is stuck/leaking/corroded, replacing it during install can prevent future leaks (and future service-call charges).

How to Save Money on Dishwasher Installation

• Prep access: Empty the under-sink area and make sure the space around where your dishwasher will go is clear.
• Bundle add-ons: Replacing a valve or hose during installation is usually cheaper than a separate visit. While it won’t save you money up front, it will save money on maintenance and repair costs down the line.
• Compare quotes by scope: Ask whether the quote includes haul-away, new hoses/lines, air gap work, and testing.
