How much does it cost to install a washer outlet box?
The price to put in washer and dryer hookups averages between $350 and $600 if theyre placed in an ideal location. If the appliances end up in a spot thats further from your existing plumbing, you could end up paying anywhere from $700 to $2,000 or more. Washers take a standard 120V outlet.
