Dishwasher installation is one of the most affordable plumbing projects, with a national average cost of about $400 for professional installation of a standard built-in unit. Costs range from $150 for a basic swap where existing connections are reused to $600 or more for a first-time installation that requires new water supply, drain, and electrical connections. Most installations are completed in 1–2 hours, making this a quick and straightforward project for a licensed plumber or appliance installer.
The cost of dishwasher installation depends primarily on whether you are replacing an existing unit or installing one for the first time. A replacement in an existing opening with working water, drain, and electrical connections is a straightforward job that takes about an hour. A first-time installation is more involved: the installer must tap into the hot water supply line under the sink, connect a drain hose (often with a high loop or air gap per code), and ensure a dedicated electrical circuit is available.
A dishwasher requires three connections: a hot water supply line, a drain connection, and electrical power. The water supply is typically tapped from the hot water shut-off valve under the kitchen sink using a dual-outlet valve or a tee fitting. The drain hose connects to the sink's drain tailpiece or garbage disposal. Most building codes require either a high loop in the drain hose or an air gap device mounted on the countertop or sink to prevent backflow. Electrical requirements include a dedicated 15- or 20-amp circuit, which most kitchens already have.
Certain installation scenarios add complexity and cost. If the dishwasher opening needs to be enlarged or reduced to fit a different-size unit, cabinet modifications are required. Older homes may lack a dedicated electrical circuit, requiring an electrician to run a new line from the panel. Homes with copper supply lines may need transition fittings to connect modern braided stainless steel supply hoses. Panel-ready dishwashers require a custom cabinet panel to be fitted to the door, which may involve a carpenter.

Dishwasher installation labor is relatively low compared to other plumbing projects. A basic replacement takes 1–1.5 hours and costs $100–$200 in labor. A first-time installation takes 2–3 hours and costs $200–$400 in labor. Many appliance retailers (Home Depot, Lowe's, Best Buy) include basic installation with purchase, though this typically covers only a simple swap with existing connections. Independent plumbers charge more but handle complex installations and code compliance.
A basic dishwasher swap takes about 1 hour. First-time installations take 2–3 hours. Complex installs with electrical work take 3–4 hours.
If you are replacing an existing dishwasher with the same-size unit and all connections are in good condition, DIY installation is feasible for handy homeowners. The process involves sliding out the old unit, disconnecting three connections (water, drain, electric), connecting the new unit, and sliding it into place. First-time installations involving new plumbing and electrical work should be done by a licensed professional.
Installation quotes typically cover labor and basic connection materials only — not the dishwasher itself. Standard built-in dishwashers range from $400 to $1,200 depending on brand and features. Many retailers offer bundled pricing with free or discounted basic installation when you purchase the appliance through them.
A straightforward replacement takes about 1 hour. A first-time installation with new water, drain, and electrical connections takes 2–3 hours. If cabinet modifications or a new electrical circuit is needed, allow 3–4 hours total. The dishwasher is usable immediately after installation.
