In This Article

    If laundry at your house means hauling baskets to a dark basement corner, or you have no machines at all, a dedicated laundry room has probably crossed your mind. Getting one costs anywhere from $2,000 for a refresh of an existing space to $50,000 or more for a full addition, and where your project lands in that range comes down to decisions you control: the location, how far plumbing has to travel, and whether you convert space you already have or build new. The cost breakdowns, construction steps, and location comparisons below cover each of those decisions in order.

    How much does a laundry room renovation cost?

    Most laundry room renovations cost $2,000 to $15,000, with typical projects running $6,000 to $10,000. Where you fall in that range depends on three things: how much of the room you're changing, whether plumbing and electrical already exist where you need them, and the finishes you choose.

    At the low end, a cosmetic laundry remodeling project covers new flooring, paint, shelving, and maybe a countertop over the machines. At the high end, you're relocating plumbing, adding a sink, installing custom cabinetry, and possibly moving the room to a new part of the house.

    If you're adding a laundry room to a house that has never had one, budget separately for the build itself. Converting existing interior space typically runs $5,000 to $15,000, while a small addition that expands your home's footprint can run $20,000 to $50,000 or more once foundation, framing, and roofing enter the picture.

    Here's what typical project scopes look like as planning scenarios:

    • Cosmetic refresh, $2,000 to $5,000. This scope covers new flooring, paint, open shelving, and a counter over existing machines, with no plumbing or electrical changes.
    • Closet conversion, $6,000 to $10,000. A hallway closet gets stacked machines, new supply lines, a drain, a dryer circuit, and venting to an exterior wall.
    • Second-floor relocation, $12,000 to $20,000. Laundry moves from the basement to a bedroom-level closet or spare room, with new plumbing runs, leak protection, and reinforced subflooring.
    • Small bump-out addition, $30,000 to $50,000 or more. A new 6 by 8 foot room gets built onto the house, covering foundation, framing, roofing, and the full laundry fit-out.

    What factors affect laundry room renovation cost?

    Plan your budget around these line items. All figures are planning ranges, and your quotes will vary by region and project scope.

    • Flooring: $300 to $900. Laundry rooms need water-resistant flooring that can take detergent spills and appliance vibration. Luxury vinyl plank and ceramic tile are the standard choices. Vinyl is cheaper and softer underfoot, while tile holds up better under heavy machines over decades.
    • Subflooring: $150 to $500. If the existing subfloor shows water damage or the room sits above living space, replacing or reinforcing it protects everything you install on top. This matters most for second-floor laundry rooms, where a failed subfloor means ceiling damage below.
    • Cabinets: $250 to $2,000. Stock upper cabinets over the machines are the budget option. Custom cabinetry with pull-out hampers and vertical broom storage sits at the top of the range.
    • Countertops: $300 to $1,400. A counter over front-loading machines creates a folding station without taking up extra floor space. Laminate and butcher block cover the low end, while quartz and granite cost more but hold up better against detergent and bleach.
    • Electrical: $500 to $1,500. Dryers need a dedicated 240V circuit, and code requires GFCI protection for outlets near water sources. Older 100-amp panels often have no open slots for that circuit, and a panel upgrade adds $1,500 to $3,000, which is one of the most common mid-project surprises. A licensed electrician handles this portion.
    • Plumbing: $1,000 to $2,500 for new hookups. Washer supply lines, a drain standpipe, and a shutoff valve are required for any new location. Adding a utility sink adds roughly $400 to $1,000 on top. If water lines need to travel far from the existing stack, costs climb. Our guide to rerouting plumbing costs covers what to expect.
    • Dryer ventilation: $200 to $600. Dryers must vent to the exterior through smooth rigid ducting. Long or twisting vent runs trap lint, reduce efficiency, and create a fire risk, so the shortest path to an exterior wall is the goal.
    • Appliances: $1,200 to $4,000 for a washer and dryer pair. Installation and haul-away often add $100 to $300 unless the retailer includes them. A $20 to $50 automatic water shutoff valve is cheap insurance against a burst supply hose, which causes more damage than any other laundry room failure.
    • Labor: 30 to 50% of total project cost. Simple installs bill hourly, while full renovations are usually quoted as a fixed bid covering carpentry, plumbing, electrical, and finish work. Handling cosmetic tasks like painting and shelving yourself can trim 10 to 20% off a laundry remodeling budget, but everything inside the walls belongs to licensed trades.

    Adding a laundry room to a house: conversion vs. addition

    If your home doesn't have a laundry room, you have two paths. Converting existing space is almost always cheaper, because the shell of the room already exists. Building an addition makes sense only when there's genuinely no interior space to spare.

    • Converting existing space means claiming part of a garage, basement, oversized bathroom, closet, or mudroom. The main costs are running water supply, drain, and electrical to the new location, plus finishes. Expect $5,000 to $15,000 for most conversions, with the biggest variable being how far the plumbing has to travel from your home's existing wet walls.
    • Building an addition means new foundation, framing, roofing, and exterior finishes before any laundry-specific work begins. Even a small 6 by 8 foot bump-out often runs $20,000 to $50,000 or more. Most homeowners who go this route pair the laundry room with a larger project, like a mudroom or primary suite addition, to spread the structural costs across more usable space.

    Laundry room cost by location

    Basement: $3,000 to $8,000

    The basement is usually the cheapest option because utilities are already close. It's also the farthest from where laundry actually accumulates, and many homeowners and buyers consider it the least desirable location for exactly that reason. Kristen Herhold, Director of Public Relations at Clever Real Estate, works with home buyer and seller research daily and has watched the location question play out in showings:

    Kristen Herhold

    "What homeowners would be surprised buyers care about: laundry room location and storage. I've watched buyers walk out over a basement laundry more than once."

    Every load means a trip up and down stairs, and a laundry chute only solves half the problem, since clean clothes still travel back up by hand. Moisture is the other drawback. Budget for waterproof flooring and a dehumidifier or ventilation, and if the space has a history of dampness, read our guide on waterproofing a basement first.

    Laundry closet: $2,500 to $8,000

    A laundry closet is a hallway or bedroom closet fitted with stacked machines, and it's the most space-efficient option for condos and smaller homes. The conversion depends on a recessed supply box in the wall so the machines can sit flush, a workable drain path to the nearest stack, and a door style that fits the opening. Bifold and sliding doors save swing space, while louvered doors add the airflow an enclosed closet needs to shed heat and humidity. Sound insulation around the closet walls is worth the modest cost if the closet sits near bedrooms. Our guide to converting a closet into a laundry room walks through the full project.

    Garage: $1,500 to $5,000

    This range covers setting up laundry within an existing garage, not a garage addition. It's cheap if plumbing is nearby, but garages lack climate control in most of the country, and freezing temperatures are hard on machines and can ruin liquid detergent. Insulation or a heat source may be necessary depending on your climate.

    Mudroom: $4,000 to $9,000

    Pairing laundry with a mudroom is natural, since dirty clothes and dirty shoes enter the house at the same door, and many mudrooms already have plumbing nearby. The drawback is congestion. The mudroom is your home's busiest entry, and machines, drying racks, and baskets compete with coats, boots, and people coming through the door. It works best in mudrooms of 60 square feet or more, where the two functions get their own zones.

    Upstairs near bedrooms: $8,000 to $15,000 or more

    Upstairs is the most convenient location, since that's where most laundry originates, and the most expensive, because of the plumbing runs and the leak protection an upper-floor install demands. A drain pan, a water sensor with automatic shutoff, and anti-vibration pads are non-negotiable here.

    The premium is worth more than most homeowners give it credit for. Location is the one part of a laundry room you can't upgrade later without redoing the plumbing, so if the budget forces a choice, spend on placement and save on countertops and cabinets. The leak risk that scares people off is largely addressed by $200 in sensors and a drain pan.

    Inside a bathroom: $3,500 to $10,000

    Sharing a wet wall with an existing bathroom keeps plumbing costs down, and the bathroom's existing exhaust fan already handles the humidity a washer adds. Both rooms give something up, though. The bathroom loses storage or floor space to the machines, and the laundry setup gets no counter, no sorting room, and a running washer next to whoever is using the bathroom. A stacked unit in a former linen closet or alongside the vanity is the layout that costs the two rooms the least. It's a solid way to add laundry to a home that has none. Just don't expect it to work like a dedicated room. See our guide to putting laundry in a bathroom for layouts that work.

    Laundry room upgrade ideas worth the money

    If your laundry room functions but doesn't work well, a targeted laundry room upgrade costs far less than a full renovation. These are the additions homeowners use daily.

    • Counter over front-loaders: $300 to $1,400. This is the single highest-impact upgrade. A continuous folding surface gives you somewhere to fold and sort instead of carrying baskets to the nearest bed.
    • Retractable drying rack: $50 to $400. Wall-mounted racks fold flat when not in use and eliminate the delicates draped over doorknobs. A ceiling-mounted pulley rack works in rooms with height to spare.
    • Utility sink: $400 to $1,000 installed. A sink handles pre-treating stains, hand-washing, and everything too messy for the kitchen. Stainless steel cleans up easier and lasts longer than the standard plastic tub.
    • Pull-out hamper cabinets: $200 to $800. Built-in sorting bins for lights, darks, and delicates keep the floor clear and cut a step out of every load.
    • Better lighting: $150 to $500. Laundry rooms are chronically under-lit. Bright overhead LEDs plus under-cabinet lighting over the counter make stain-spotting and sock-matching much easier.
    • Automatic water shutoff: $20 to $150. A sensor kills the water supply when it detects moisture on the floor. The washer poses the bigger risk. A burst supply hose can release hundreds of gallons an hour, usually while nobody is home, and washing machine failures rank among the most common sources of residential water damage claims.

    Building a laundry room: what the process looks like

    A typical laundry room build or full renovation runs two to four weeks once work starts. Here's the sequence.

    1. Design and permits, 1 to 4 weeks before construction. Finalize the layout, confirm appliance dimensions, and submit permit applications. Stacked machines need about 30 inches of width and 80 inches of height, while side-by-side setups need roughly 60 inches of width. Confirm the dryer vent route now too: the International Residential Code caps the run at 35 feet, each 90-degree elbow deducts about 5 feet, and a room two turns away from an exterior wall may not work for a vented dryer at all. If no workable route exists, a heat-pump dryer needs no exterior vent and runs on a standard 120V outlet, which opens up interior rooms at the cost of longer cycle times and a higher purchase price. Local codes vary, so confirm requirements with your contractor.
    2. Demolition and framing, 1 to 3 days. Existing finishes come out, and any new walls or door openings go up.
    3. Rough-in plumbing and electrical, 2 to 5 days. Supply lines, the drain standpipe, the dryer circuit, and outlet boxes are installed inside open walls. This stage gets inspected before walls close.
    4. Ventilation, 1 day. The dryer duct runs to the exterior along the route confirmed during design. If the room has no window, an exhaust fan handles humidity, which matters for preventing mold in enclosed laundry spaces.
    5. Drywall, flooring, and paint, 3 to 5 days. Walls close up, water-resistant flooring goes down, and the room gets finished surfaces.
    6. Cabinets, countertops, and fixtures, 2 to 4 days. Storage, the folding counter, the utility sink, and lighting are installed.
    7. Appliance hookup and final inspection, 1 day. Machines connect, everything gets leveled, and the inspector signs off on the permitted work.

    One decision worth making early is stacked versus side-by-side machines. Stacking saves floor space but limits you to front-loaders and can complicate hookups depending on where the pipes sit in the wall. Side-by-side placement opens up counter space above and is easier on anyone who doesn't want to reach overhead for the dryer.

    Laundry room requirements: what code expects

    Building codes treat a laundry room as a wet room with heat-producing appliances, and inspectors check a consistent set of items regardless of where the room sits in the house. Local codes vary, so treat these as the common baseline and confirm specifics with your building department.

    • Electrical circuits. Electric dryers need a dedicated 240V, 30-amp circuit. The washer runs on its own 120V, 20-amp laundry circuit, and receptacles in the laundry area require GFCI protection under current code cycles.
    • Drainage. The washer drains into a 2-inch standpipe with a trap, and the standpipe opening typically has to sit 18 to 42 inches above the trap. An undersized drain line is a common cause of overflow in older homes retrofitted with modern high-volume washers.
    • Drain pan above living space. Many jurisdictions require a drain pan under a washer installed over a finished floor below, and a pan needs somewhere to send the water, which means a drain line or an approved sensor shutoff depending on local rules.
    • Dryer venting. The duct must be smooth rigid metal, terminate outdoors with a backdraft damper, and stay within the length limit, which the International Residential Code sets at 35 feet with deductions for each elbow. Venting into an attic, crawl space, or garage fails inspection everywhere.
    • Gas dryers. A gas dryer adds a shutoff valve requirement and, in tight enclosures, makeup air so the appliance can draft properly.
    • Space and access. Appliance alcoves need the manufacturer's minimum clearances, and the room needs enough clear floor for doors to open fully. Our laundry room sizing guide covers minimum and average dimensions in detail.

    How to choose a contractor for a laundry room renovation

    Laundry rooms are small, but they touch plumbing, electrical, ventilation, and carpentry in a compact space. Before committing to a layout, have a plumber and an electrician look at the space: confirming that the panel has capacity for a dryer circuit and that the drain run is feasible catches the two most expensive surprises before they show up as mid-project cost increases. From there, look for a general contractor who has completed similar utility-room projects, not just kitchens and bathrooms, and confirm the following before signing:

    1. Get the scope and exclusions in writing. The quote should itemize demolition, rough-in work, finishes, appliance hookup, and cleanup, so nothing shows up later as an extra.
    2. Confirm who pulls permits. Be wary of any contractor who suggests skipping permits on new plumbing or electrical work.
    3. Require licensed trades for licensed work. Ask whether the plumbing and electrical will be done by licensed subcontractors or in-house licensed staff, and get their license numbers.
    4. Expect a realistic timeline with inspection milestones. Two to four weeks is typical for a full renovation. A quote promising three days for a project involving new plumbing deserves skepticism.
    5. Ask for references from comparable projects. Ask past clients how the contractor handled unexpected problems mid-project, since finished photos won't show you that.

    Frequently Asked Questions

    How much does it cost to add a laundry room to a house?

    Converting existing interior space into a laundry room typically costs $5,000 to $15,000, depending on how far plumbing and electrical need to travel. Building a laundry room as a new addition, with foundation and framing, often runs $20,000 to $50,000 or more.

    Does a laundry room renovation add value to a home?

    A functional, well-located laundry room is a consistent buyer priority, particularly in markets where in-unit laundry isn't guaranteed. Location and storage matter more to buyers than finishes, and main-floor or bedroom-level laundry generally shows better than basement setups.

    What is the average size of a laundry room?

    Most laundry rooms fall between 35 and 100 square feet. A minimal closet setup with stacked machines fits in about 35 square feet, while 80 to 100 square feet allows side-by-side machines, a counter, cabinets, and a sink.

    Do I need a permit to add a laundry room?

    In most jurisdictions, yes. New plumbing, new electrical circuits, and structural changes all typically trigger permit requirements, and additions must also meet zoning rules. Check with your local building department, and confirm your contractor is handling the permitting.

    Can I put a laundry room on the second floor?

    Yes, and it's the most convenient location for most households. Plan for a drain pan under the washer, a water sensor with automatic shutoff, anti-vibration pads, and solid subflooring. These protections address the main risk of upper-floor laundry, which is water damage to the rooms below.
