Installing a dishwasher typically costs $150 to $400 in labor when you are replacing an old one and the water, drain and power are already in place. A first time install in a new spot usually runs $600 to $1,800 because it needs a water line, drain connection, dedicated circuit and cabinet work. Most dishwashers add $400 to $1,500.

How much does it cost to install a dishwasher?
The answer depends almost entirely on what is already under your counter. A straight swap, where a standard 24 inch dishwasher replaces another in the same opening, takes one to three hours. The installer disconnects the old unit, sets the new one, connects the water supply, drain hose and power, levels it, secures it to the counter and runs a test cycle. Most homeowners pay $150 to $400 for that labor.
Prices climb when the old hookups are worn or do not match. A corroded shutoff valve, a supply line that is too short, a drain that needs a new connection at the disposal or sink tailpiece, or a plug in model replacing a hardwired one each add $50 to $200. Many retailers include basic installation with purchase but charge extra for new parts and haul away.
What does a first time dishwasher installation involve?
Adding a dishwasher to a kitchen that never had one is a small remodel. Expect several trades worth of work:
- Cabinet work. A 24 inch base cabinet, usually next to the sink, is removed and the opening trimmed. Countertop support may be needed.
- Water supply. A hot water line with its own shutoff is run from under the sink.
- Drain. The drain hose connects to the garbage disposal or a dishwasher tailpiece, with a high loop or air gap to keep dirty sink water out.
- Electrical. Most manufacturers call for a dedicated 15 or 20 amp circuit, and current code calls for GFCI protection on dishwasher circuits in homes.
- Finish work. Flooring under the unit, toe kick trim and any countertop patching.
All of that typically runs $600 to $1,800 before the price of the dishwasher. The electrical side is often the biggest single piece; our guide to types of electrical circuits explains why kitchen appliances get their own circuits.
Before booking, measure the opening width, height and depth, check whether the old unit plugs in or is hardwired, and look under the sink for a shutoff valve on the hot water line. Sharing those details and a photo or two up front keeps the price from changing on install day.
What affects dishwasher installation cost?
- Existing hookups. Reusing good water, drain and power connections is the biggest money saver.
- Hardwired vs plug in. Some models come with a cord; others are wired directly into a junction box. Switching between the two adds a little time.
- Stone countertops. Granite and quartz usually require side mounting brackets instead of screws into the underside of the counter.
- Panel ready models. Mounting a custom cabinet panel on the door adds labor and the cost of the panel.
- Floor height. New flooring installed around an old dishwasher can trap it, or leave too little room for the new one.
- Garbage disposal. If you are replacing the disposal at the same time, do both in one visit. See our garbage disposal installation cost guide.
Does the type of dishwasher change installation cost?
Yes. Standard 24 inch built in dishwashers are the simplest, because nearly every kitchen and every installer is set up for them. Other styles change the job:
- 18 inch compact models fit small kitchens and condos but may need a filler panel or cabinet changes if they replace a 24 inch unit.
- Drawer dishwashers often need two water and drain connections and cost more to install, typically $300 to $700 in labor.
- Panel ready models need a custom door panel attached and careful alignment with the cabinets around them.
- Portable and countertop models connect to the kitchen faucet and need no installation, which makes them a good option for renters.
Can you install a dishwasher yourself?
A straight replacement is a reasonable DIY project if you are comfortable shutting off water and power and working in a tight space. You will need a new supply line, a 90 degree elbow fitting, the right power cord or wire connectors, and an hour or two. The common mistakes are drain hoses without a high loop, overtightened fittings that leak later, and units that are not secured to the counter and tip forward when the door opens.
A first time installation is usually best left to a professional, because it involves new plumbing and a new electrical circuit, which often need a permit. A slow leak under a dishwasher can rot a subfloor for months before anyone notices.
How long does a dishwasher last, and when should you replace it?
| Situation | Repair or replace? |
|---|---|
| Under 5 years old, single part failure | Usually repair |
| 5 to 9 years old, repair under $200 | Repair |
| Over 9 years old or repair over half the cost of a new unit | Replace |
| Rust inside the tub or leaks from the tub | Replace |
Most dishwashers last 9 to 12 years. Hard water, skipped filter cleaning and a broken door seal shorten that.

Frequently asked questions
How much does it cost to install a dishwasher in 2026?
Replacing a dishwasher where hookups already exist typically costs $150 to $400 in labor. Installing one where there was none usually costs $600 to $1,800 for plumbing, electrical and cabinet work. The dishwasher itself typically adds $400 to $1,500, and haul away of the old unit is often $25 to $100.
How long does a dishwasher installation take?
A straight replacement usually takes one to three hours. A first time installation, with a new water line, drain connection, electrical circuit and cabinet removal, can take most of a day and sometimes needs separate visits for the electrical work and an inspection.
Does a dishwasher need its own circuit?
Most manufacturers recommend a dedicated 15 or 20 amp circuit, and current electrical code calls for GFCI protection on dishwasher circuits in homes. Sharing a circuit with a disposal is sometimes allowed if the combined load fits, but check the installation manual and local rules before connecting.
Is dishwasher installation included when I buy one?
Many retailers include or offer basic installation for a fee, but it usually covers only a straight swap with existing hookups. New supply lines, electrical changes, cabinet work and countertop brackets are often extra, so read the fine print and confirm whether haul away is included.
Can I install a dishwasher where there was none before?
Yes. It usually means removing a 24 inch base cabinet next to the sink, running a hot water line and a drain connection, and adding a dedicated electrical circuit. Expect $600 to $1,800 for the work, and check whether your city requires permits for the new plumbing and wiring.
