Plan to spend an average of $12,000 for a mudroom addition, although most homeowners fall within a range of $6,500 to $18,000. That breaks down to $100 to $300 per square foot, depending on your location, the size of your build, and the finishes you select. A well‑designed mudroom keeps dirt in check, streamlines storage, and adds everyday value to your home. Hiring a local home builder helps ensure your project aligns with local building codes, runs smoothly, and meets the needs of your household.
Mudroom Addition Cost Factors
Most homeowners spend $6,500 to $18,000—or $100 to $300 per square foot—on a mudroom addition. Your final bill depends on factors such as your location, the square footage you add, and whether you opt for budget-friendly or premium finishes.
Size
Expect to pay $100 to $300 per square foot for a mudroom, compared with $80 to $200 for a typical home addition. Prices climb toward the higher end when the work is more complex—think second‑story expansions or structural changes.
| Mudroom Size (Sq. Ft.) | Conversion | Addition |
|---|---|---|
| 36 | $1,800–$3,600 | $3,600–$10,800 |
| 49 | $2,450–$4,900 | $4,900–$14,700 |
| 64 | $3,200–$6,400 | $6,400–$19,200 |
| 81 | $4,050–$8,100 | $8,100–$24,300 |
| 100 | $5,000–$10,000 | $10,000–$30,000 |
| 120 | $6,000–$12,000 | $12,000–$36,000 |
Labor
Hiring a general contractor streamlines the process of adding a mudroom to your home. Most pros charge 10% to 20% of the total project price, or $50 to $150 an hour for smaller tasks. A seasoned building pro coordinates subs, keeps permits on track, and helps the build stay on schedule.
Additional Mudroom Cost Factors
A basic mudroom runs about $12,000, but upgrades—like built‑ins or a dog‑wash station—raise the price and the room’s day‑to‑day usefulness.
| Mudroom Add-On | Average Price |
|---|---|
| Cabinets | $300–$600 per cabinet |
| Lockers | $1,000–$1,250 |
| Faucet and sink | $500–$1,200 |
| Dog wash area | $2,000 |
| Flooring | $3–$25 per sq. ft. |
| Wall features | $1–$40 per sq. ft. |
Cabinets
Custom mudroom cabinets range from $300 to $600 each, making them a smart splurge if you need closed storage for backpacks, hats, or pet gear.
Lockers
Plan to spend $1,000 to $1,250 for professionally built mudroom lockers, or closer to $500 if you’re handy enough to DIY the project.
Faucet and Sink
Budget $500 to $1,200 for a mudroom sink and faucet. Most homeowners opt for a deep utility basin for rinsing boots, watering plants, or quick cleanup, but a compact hand-washing sink also works well if space is tight.
Dog Wash Area
A built-in dog wash station costs $2,000 to $3,000, and the addition of custom tile or glass can further increase the price. For a budget-friendly workaround, a roomy utility sink will suffice if your pup can still fit.
Flooring
Expect to spend $3 to $25 per square foot on mudroom flooring. Opt for water-resistant, durable options, such as vinyl plank or ceramic tile, so muddy shoes and snow boots won’t damage your new space.
Wall Features
Accent walls start at $1 to $40 per square foot. Board-and-batten, shiplap, or decorative panels fall between $10 and $40, adding instant character.
DIY Mudroom Addition vs. Hiring a Pro
If you’re simply turning a closet into a mini mudroom, a confident DIYer can usually tackle the job, though you may still want a carpenter for built‑in benches or lockers. Building a bump‑out or converting a bigger space is much more complex. Leave structural work to a licensed building pro who can pull permits, meet code, and keep the project (and you) safe, all while protecting your home’s value.

Frequently Asked Questions
Expect to spend $15 to $60 per square foot to remodel a mudroom. Your final bill depends on the extent of the facelift, the materials you select, and whether you add custom benches, cabinets, or new lighting. Because mudrooms are compact, the cost per square foot tends to be higher than that of larger rooms. For the most accurate figure, compare bids from at least three local remodel pros who can review your exact plans.
A pro will charge an average of $530—or $2.75 per square foot—to paint a six-by‑six‑foot mudroom. That price includes preparation work, two coats of high-quality paint, and meticulous finishing for a smooth, moisture-resistant surface. The right paint job withstands muddy shoes, wet jackets, and daily traffic while keeping the room looking fresh for years.
Most families do well with a six‑by‑six‑foot mudroom, while busy households or gear‑heavy hobbies may need closer to seven-by-nine. Both footprints leave room for benches, hooks, and built‑ins without feeling cramped. Aim for at least a six-by-six space so you can stash coats, backpacks, and shoes while still moving around comfortably.
If you’re building a bump‑out, you’ll need a dedicated foundation to support the new space. Converting a room inside the home often allows you to rely on the existing foundation, as new footings can add a sizable chunk to the budget. Factor this cost in early when weighing an addition versus a simple conversion.
Porcelain and ceramic tile are the top options for mudrooms because they’re durable, water-resistant, and easy to wipe clean after a messy day outside. Sealed concrete, stone, or luxury vinyl plank are solid runners‑up if you prefer a different look but still want tough, low‑maintenance flooring that can handle boots, paw prints, and daily traffic.
