The job splits cleanly. If the laundry space already has hot and cold shutoffs, a standpipe, and an outlet, hooking up a washer is $100 to $300 in labor and takes about an hour. If those connections don’t exist, you’re running supply lines, a drain, and electrical, $650 to $2,500, with $1,200 typical. Homeowners in Columbus adding laundry to a room that never had it should budget for the second number.

Code is specific about the drain, and this is where DIY installs fail inspection. The standpipe has to be at least 2 inches in diameter, typically 18 to 30 inches tall, and taller than the washer’s flood rim so water can’t siphon back. It connects to a P-trap sitting 6 to 18 inches off the floor. The drain hose drops in loosely, never sealed so air can break the siphon.

Two details save homeowners thousands. Replace the rubber supply hoses with braided stainless steel rated to 1,500 psi or better; burst washing machine hoses cause more insurance claims than almost any other plumbing failure, and the upgrade costs under $30. And level the machine properly; an unlevel washer walks, vibrates, and eventually damages its own pump and the drain connection. Plumbers in Columbus handle both as part of a standard hookup.

New hookups almost always need a permit, since they modify plumbing and electrical. Moving laundry to another floor or the garage runs $1,200 to $5,000 once you count new drain lines, outlets, and drywall repair. Below you’ll find licensed plumbers handling washing machine installation in Columbus, new hookup rough-in, standpipe and P-trap work, shutoff valves, and relocations. Ask each quote to specify whether hoses, a drain pan, and permit fees are included.

How much does washing machine installation cost?

With existing hookups, $100 to $300 in labor for about an hour of work. Installing new hookups where none exist runs $650 to $2,500, averaging around $1,200. Relocating laundry to another floor, a basement, or the garage costs $1,200 to $5,000. Plumbers charge $45 to $150 an hour, and electricians $50 to $130. Prices sit in these ranges. Permits add $150 to $300, and a new washer outlet another $100 to $300. Delivery and haul-away are usually billed separately.

What does a washing machine hookup need?

Four things: hot and cold supply lines with individual shutoff valves, a drain standpipe, an electrical outlet, and enough floor space. Supply lines are half-inch copper, PEX, or PVC, usually terminating in a recessed washer box. The standpipe must be at least 2 inches in diameter with a P-trap. The outlet is a standard 120V receptacle; washer dryers need more. Plumbers verify all of this before quoting a new hookup. Accessible shutoffs are a code requirement, not optional.

How high should the washer standpipe be?

Typically 18 to 30 inches above the floor, and always higher than the washer’s flood rim so water can’t siphon back into the machine. The P-trap sits 6 to 18 inches off the floor, within about 24 inches of the standpipe base. Diameter must be at least 2 inches to handle modern pump discharge rates. Too low causes overflow; too high can pull the trap dry. Local amendments vary, so have plumbers confirm the numbers before rough-in begins.

Can I install a washing machine myself?

With existing hookups, yes, it’s about an hour of work. Connect hot and cold hoses (hot to hot, cold to cold), hook the drain hose over the standpipe without sealing it, plug in, level the machine, and run a cycle, watching for leaks. Skip DIY when hookups don’t exist, since that’s plumbing and electrical work requiring permits. Call a plumber if the shutoff valves are seized or the standpipe backs up during the test. Both are common problems.

Should I replace the washing machine hoses?

Yes, and do it during installation. Burst washer hoses are one of the most common causes of household water damage claims; a failure at line pressure floods a room in minutes. Replace the rubber hoses that ship with most machines with braided stainless steel rated to at least 1,500 psi, for under $30. Replace them every five years regardless of appearance. Plumbers include this in most installations, but confirm it’s in the quote. It is the cheapest insurance in the room.

Do I need a permit for new washer hookups?

Yes in most jurisdictions, because new hookups modify plumbing, electrical, or both. Permits run $150 to $300 and cover an inspection of the standpipe height, P-trap placement, drain diameter, supply shutoffs, and outlet wiring. Simply replacing a machine on existing hookups doesn’t require one. Unpermitted laundry plumbing is a common finding during home sales. Confirm requirements with the building department and let your plumber pull whatever the job needs. Rules vary widely from one jurisdiction to the next.

How much does it cost to move laundry to another room?

Short moves within the same room run $500 to $2,000. Relocating upstairs, to a basement, or out to the garage costs $1,200 to $5,000 once you add a new drain line at $360 to $1,840, outlets at $100 to $500 each, and drywall repair at $300 to $1,000. A gas dryer adds gas line work. Distance from existing plumbing drives most of the cost. Get three itemized bids from plumbers. Second-floor installs usually also need a drain pan.

Very expensive. Make sure you establish the price up front. They did some work on gas pipes, which was specialized so the prices weren't so horrible.

They never called my property manager, or myself, to ask if they could do an additional estimate while at my property. I was shocked. Companies cannot go around doing estimates.
