| Mudroom Location | Average Cost |

Cost to Enclose a Porch to Make a Mudroom
Enclosing a 200-square-foot porch to create a mudroom starts at $2,500 for a basic screened-in enclosure. Adding solid walls and fully enclosing the space can cost several thousand dollars more. Consult a general contractor who can provide a quote and design ideas.
Average Cost to Convert a Closet Into a Mudroom
You’ll pay between $1,800 and $3,600 to convert a 36-square-foot closet into a mudroom.
One of the advantages of converting a closet into a mudroom is that it takes much less time and materials, and you may not need to replace or install new flooring. A drawback is that you have much less space. You can fit a bench, some bins, and coat hooks, but it won't contain the mess from muddy or snow-covered boots like a traditional mudroom.
Cost of Bump-Out Mudroom
A bump-out mudroom can range from $10,000 to $36,000, but costs depend 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.
Cost of Basement Mudroom
If you have a walk-out basement, you can convert a portion of it into a mudroom for $7,000 to $25,000. The cost includes waterproofing and finishing the space and rerouting any exposed utilities like plumbing pipes or electrical wires.
Additional Costs to Building a Mudroom
Building a mudroom costs an average of $12,000 for a basic design. Adding certain features can increase the price but will create a more functional space.

Mudroom Benches
A custom-built mudroom bench costs between $250 and $2,000 or more, depending on design and materials. Hiring a carpenter costs between $35 and $100 per hour, though some may charge a flat rate for the project. Built-in benches with storage options are on the higher end of the price range.

Mudroom Shower
If your mudroom has the space, you could add a shower for $4,000 to $12,000. The cost to install a shower depends on the size, whether it is custom or prefabricated, and how much plumbing work is involved. Showers in a mudroom tend to be small stall showers for cleaning off after gardening or swimming.
Mudroom Dog Wash Area
The price to install a dog wash area runs around $2,000, 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 in it.
Mudroom Flooring
Mudroom flooring costs between $3 and $30 per square foot to install, depending on the material. Water-resistant and durable materials like vinyl ($3 to $25 per square foot) or tile ($3 to $30 per square foot) are excellent choices for a mudroom.
Mudroom Wall Features
To make a statement in your mudroom, consider adding a wall feature for $1 to $40 per square foot. For a less expensive option, paint an accent wall for $1 to $30 per square foot. If you are looking for something more impactful, consider board and batten, wall panels, or shiplap features, ranging from $10 to $40 per square foot.
DIY Mudroom Addition vs. Hiring a Pro
Converting a closet into a mudroom is a feasible DIY project for some homeowners, but you'll still need a carpenter for custom benches and lockers.
For building a new addition or converting a larger space, it's best to hire a professional. Taking on structural engineering without proper experience can cause serious injuries if something were to go wrong. Professionals have the skills and experience to ensure the project is completed safely and meets all building codes, enhancing your home's value.
