What does a washer hookup cost?
A washer hookup close to existing water and drain lines costs roughly $350 to $700 as a US planning range: a valve box, a standpipe or trap, and the labor. A brand-new laundry spot far from the lines is a different job: add roughly $400 to $1,040 for extending supply lines and $1,080 to $2,250 if the drain has to travel too.
What drives the price
- Distance to existing supply and drain lines: the main driver.
- Drain routing: a standpipe next to an existing stack is easy; a new run under the floor is not.
- An electric dryer: a 240V circuit is a separate electrician item.
- Slab floors and finished walls: opening and restoring them is where budgets slip.
Ranges are national planning figures (validated August 2026). Always get local quotes; labor varies a lot by state and metro.

In the free bathroom planner you can drag a washing machine anywhere in the room: next to the lines it is quiet, far away the extra plumbing shows up in the estimate while you drag.
Frequently asked questions
What does a washer connection actually need?
Hot and cold supply valves, a drain (standpipe or laundry sink) with a trap, and a grounded outlet. An electric dryer adds a 240V circuit, which is an electrician line item on top of the plumbing.
Can I put the washer anywhere in the house?
Technically often yes, financially not really. The further from existing supply and drain lines, the more walls and floors open up. Upstairs laundry also wants a drain pan and a shutoff you can reach.
How do I see the cost for my own layout?
Drag a washing machine into the free bathroom planner: put it next to the existing lines and the hookup stays modest; drag it across the room and you see the extra plumbing appear in the estimate live.
