Dishwasher installation cost: basic to upgraded, by state
A mid-range dishwasher: about $1,000 to $1,200, typically $1,100. That's a new built-in dishwasher set in the existing opening and connected, with the old one taken out, plus the contractor's overhead, profit and sales tax. A new water line, drain or circuit where there wasn't one, cabinet changes and permits are extra.

What it costs
| Job | Cost |
|---|---|
| A basic dishwasher | $800 to $1,000 |
| A mid-range dishwasher | $1,000 to $1,200 |
| An upgraded dishwasher | $1,400 to $1,600 |
Totals include the contractor's overhead and profit (20%) and the state's average sales tax. Prices as of November 2026.
What’s in these numbers
Each total is a typical job, priced the way a contractor’s estimate is priced:
- A new built-in dishwasher of the grade shown, set in the existing opening and connected, with the old one taken out.
- Overhead and profit: 20%, the standard markup on a contractor’s estimate.
- Sales tax on the materials, at the state’s average rate.
Not in them: running a new water supply, drain or circuit where there was no dishwasher before, cutting a cabinet to make an opening, and permits.
Replacing or adding
These totals swap a dishwasher for a new one in the same opening, where the water, drain and power are already there. Adding a dishwasher to a kitchen that never had one is a bigger job: a cabinet comes out to make the opening, and the supply line, drain connection and circuit are new.
What moves the price
- Grade. Each step up costs more for the unit itself.
- A first install. A new opening, water line, drain and circuit are work of their own.
