Cost to Bring Plumbing Up to My Closet for Laundry

Thinking about turning your closet into a laundry nook? You’re not alone—more U.S. homeowners are embracing compact, convenient laundry setups. But before you start tearing down shelves, you’re probably asking: What’s the cost to bring plumbing up to my closet for laundry? Good news: this guide breaks down everything—from hidden fees to smart savings—so you can plan with confidence and avoid budget blowouts.

Why Do People Want Laundry in Their Closet?

Space-saving, convenience, and property value are top drivers. According to a 2023 National Association of Home Builders (NAHB) report, 68% of new single-family homes now include laundry rooms on the main or upper floor—often tucked into closets or unused nooks.

Having laundry nearby eliminates lugging clothes down to the basement or out to a garage. But retrofitting plumbing into an existing closet—especially one not originally designed for utilities—comes with unique cost factors.

What Exactly Does “Bringing Plumbing Up” Mean?

“Bringing plumbing up” refers to running new hot and cold water supply lines and a drain-waste-vent (DWV) system from your home’s main plumbing stack to your chosen closet—usually on an upper floor.

This isn’t just about connecting hoses; it’s about:

• Installing new PEX or copper supply lines
• Running a 2-inch ABS or PVC drain pipe
• Ensuring proper venting (to prevent sewer gases and maintain drainage)
• Complying with local building codes

💡 Pro Tip: Most U.S. plumbing codes require a vented drain system within 5 feet of the washing machine trap. Skipping this can lead to slow drainage or foul odors.

Average Cost to Bring Plumbing Up to My Closet for Laundry

The national average cost ranges from $2,500 to $7,500, according to HomeAdvisor and Angi (2024 data). However, your final price depends heavily on three factors:

📌 Real-World Example: In Austin, TX, a homeowner paid $5,200 to run plumbing 18 feet vertically and 12 feet horizontally from a basement utility room to a second-floor closet. The job included drywall patching, a new utility sink, and a code-compliant vent.

Step-by-Step: How Plumbing Is Installed in a Closet

If you’re planning this project, here’s what the process typically looks like:

1. Consult a licensed plumber for a site assessment (many offer free quotes).
2. Obtain permits—required in most U.S. cities for new plumbing branches.
3. Locate existing supply and drain lines (often in a basement or crawlspace).
4. Cut access paths through floors, walls, or ceilings (minimally invasive techniques preferred).
5. Install ¾-inch PEX supply lines (hot and cold) and a 2-inch PVC drain line with a P-trap.
6. Add a vent pipe tied into the main stack or install an Air Admittance Valve (AAV) if allowed locally.
7. Patch and finish walls, then install washer/dryer hookups.
8. Schedule city inspection before closing up walls permanently.

⚠️ Warning: DIY plumbing may seem appealing, but improper venting or slope errors can cause backups or code violations. The U.S. Environmental Protection Agency (EPA) notes that 23% of home water damage claims stem from DIY plumbing mistakes (source).

Key Cost Variables You Can’t Ignore

1. Home Age & Layout

Older homes may have cast iron pipes or knob-and-tube wiring, complicating access. Multi-story homes without a basement increase labor time.

2. Washer Type

Stackable units need less space but still require full plumbing. Compact washers (like Splendide) use less water but don’t reduce plumbing costs.

3. Local Labor Rates

Plumbers charge $45–$200/hour depending on location. California and New York average 30% higher than Midwest rates.

4. Material Choices

• PEX piping: $0.50–$2/ft (flexible, freeze-resistant)
• Copper: $2–$8/ft (durable but expensive)
• PVC drain: $1–$3/ft

How to Save Money Without Cutting Corners

• Place the closet near an existing bathroom—shared walls often have plumbing chases.
• Use an AAV (if code-compliant) instead of running a roof vent—saves $500–$1,200.
• Bundle with other renovations (e.g., bathroom remodel) to reduce mobilization fees.
• Get 3+ quotes—prices can vary by 40% between contractors.

FAQ: Cost to Bring Plumbing Up to My Closet for Assistant

Q1: Can I install laundry plumbing in any closet?

A: Not always. The closet needs minimum dimensions (typically 36” wide x 36” deep) and must be near a drain stack. Load-bearing walls may restrict pipe routing.

Q2: Do I need a permit?

A: Yes, in nearly all U.S. jurisdictions. Skipping permits risks fines, failed inspections, or issues when selling your home.

Q3: How long does the installation take?

A: Most jobs take 2–5 days, depending on access and drywall work. Simple runs with open framing may finish in 1 day.

Q4: What if there’s no nearby drain?

A: You may need an upflush system (like a Saniflo pump), which adds $800–$1,500 but avoids trenching floors.

Q5: Can I use existing electrical for the washer?

A: Possibly—but washers need a dedicated 120V, 20-amp GFCI outlet. Older circuits may require an electrician.

Q6: Will this increase my water bill?

A: No—unless you do more loads! Modern ENERGY STAR washers use as little as 13 gallons/load, compared to 30+ gallons for older models.
