Most homeowners pay between $8,000 and $16,000 for a 50-square foot mudroom addition, with an average project cost of $12,000. You could pay as little as $4,500 for a space of equal size, but larger rooms or bump-out additions could run upwards of $30,000.
*For a 50-square foot mudroom.
Costs vary, but most mudroom additions cost between $90 and $200 per square foot. The cost to build a house addition ranges from $80 to $500 per square foot, but higher prices are usually for more intense projects (such as building a second story addition).
Adding a small mudroom (less than 40 square feet) might cost between $90 and $200 per square foot. Your costs will vary drastically depending on if you’re converting an existing space or building an entirely new addition. Contact a home building contractor near you for an estimate when planning your new addition.
A 100-square foot mudroom averages between $10,000 and $12,000 for just the basics, such as flooring and walls.
Depending on the project you have in mind, you might want to consider these additional services:
While most mudrooms average $12,000, costs depend on the type of addition.
Adding a mudroom inside the garage will still likely run from $8,000 to $16,000 but costs can vary. Expect a lower project price if you’re adding very basic changes (such as shelves) and higher costs if you’re adding walls. The cost to install a new wall is $1,800 on average.
A bump-out mudroom can range from $17,000 to $30,000 but costs vary based on size and project complexity. Prices are higher for this type of room because it requires a new foundation, instead of converting an existing room.
Enclosing a 200-square foot porch to create a mudroom will likely cost at least $2,500, and that’s enclosing with mesh (like a screened-in porch). Adding actual walls costs several thousand dollars. Find a general contractor who can provide a quote and design ideas.
A built-in mudroom typically averages between $8,000 and $16,000. Your project costs depend on where you’re adding this type of room, as well as the size and what features you want to include.
You’ll have to talk to a contractor for an estimate on turning a closet into a mudroom, but you’ll likely pay no more than $4,500.
One of the advantages to converting a closet is that it takes much less time and materials (you might not even need to replace or install new flooring). A drawback is that you have much less space. You might only be able to fit a bench, some bins and coat hooks, and it probably won’t contain the mess from muddy or snow-covered boots like a traditional mudroom.
The national average to build a mudroom is $12,000 for a fairly basic design. Certain add-ons will impact the price but create a more comprehensive space.
|Mudroom Add-Ons||Average Price Range|
|Bench||$250 - $2,000+|
|Cabinets||$500 - $1,200 per linear foot|
|Lockers||$1,000 - $2,000|
|Dog wash area||$1,000 - $3,500|
A custom-built mudroom bench may cost anywhere from $250 to $2,000 or more. Hiring a carpenter costs between $35 and $100 per hour, though some carpenters might charge by the project. A built-in bench or seating with storage options will run on the higher end of prices.
The cost to install custom cabinets in your mudroom runs from $500 to $1,200 per linear foot for wood. Steel cabinet costs span from $1,000 to $1,500 per linear foot. For a 6-foot wall, you could pay between $3,000 and $9,000.
Mudroom lockers typically span from $1,000 to $2,000, depending on the style. Open lockers or cubbies cost less whereas closed lockers cost $2,000 or more.
The price to install a dog mudroom wash area runs between $1,000 and $3,500, though custom tubs or showers will cost more. If you’re looking for a simpler alternative, a utility sink is a great option (as long as your pet can fit). This type of sink installation costs between $40 and $200.
Some mudrooms (such as a closet conversion) are definitely doable as DIY projects, though you might need a carpenter for benches and lockers.
However, in the event of building a new addition or converting a larger space, you should absolutely hire a professional. Taking on structural engineering without proper experience is a safety hazard.
Not to mention, adding a mudroom is a great opportunity to add value to your home (when worked on by a contractor, architect and/or engineer). A poorly-built addition will lower your home’s value. Hire a contractor to build an addition for the best results.
You can add a mudroom to your house by either converting an existing space or building a home addition. If converting a space, a professional might replace flooring and add walls and/or plumbing to create a new room. For home additions, a contractor will build a new room attached to your house.
Prefab mudroom lockers can cost anywhere from $310 to $2,750 or more. Higher quality materials raise the price, as does the overall size and design.
The cost to remodel a mudroom runs from $10 to $60 per square foot on average. Because mudrooms are smaller than typical rooms, there’s a chance you might pay higher costs per square foot. Check with a home remodeling contractor near you for a price idea.
The cost to install a door for your mudroom averages around $980. Adding walls or a small hallway will likely cost at least $3,600, and this price doesn’t include any design. If you just want to convert a doorway into a mudroom, you’ll likely spend between $10 to $60 per square foot for renovation.
A single mudroom wall costs $1,800 on average to install. Depending on the design, you might need more than one wall. Expect to pay $3,600 and up for two or more walls.
Painting a mudroom with 40 square feet of wall space ranges from $80 to $240 when hiring a professional. This will cost less if you have cabinets or a window taking up some of the wall space.
