How Much Is It to Get Plumbing Installed? (2024 Cost Guide)

If you’re building a new home, remodeling a bathroom, or replacing old pipes, you’ve probably asked yourself: “How much is it to get plumbing installed?” It’s a smart question—plumbing is essential but can be a major budget item. Whether you’re a first-time homeowner or a seasoned DIYer weighing professional help, understanding real-world costs can save you thousands. Let’s break it down clearly, fairly, and with up-to-date 2024 data.

What Does “Plumbing Installation” Actually Include?

Before diving into costs, it’s important to know what “plumbing installation” covers. It’s not just about pipes—it’s the entire system that brings clean water in and waste water out. This typically includes:

• Supply lines (for hot and cold water)
• Drain-waste-vent (DWV) system
• Fixtures (toilets, sinks, showers—sometimes included, sometimes not)
• Water heater connections
• Shut-off valves and pressure regulators

Note: Some contractors quote “rough-in plumbing” (pipes in walls/floors before drywall), while others include “finish plumbing” (installing faucets, toilets, etc.). Always clarify what’s in your quote.

Average Cost to Install Plumbing in 2024

According to HomeAdvisor and Angi (formerly Angie’s List), the national average cost to install plumbing in a new home ranges from $4,000 to $15,000, depending on size, complexity, and location.

But that’s a wide range—so let’s get specific.

By Home Size:

By Project Type:

• New construction plumbing: $4–$8 per square foot
• Full home repipe: $4,000–$15,000
• Bathroom rough-in only: $800–$2,500
• Kitchen plumbing only: $600–$2,000

💡 Pro Tip: Labor makes up 60–70% of total plumbing costs. Materials (copper, PEX, PVC) account for the rest.

What Factors Affect Plumbing Installation Costs?

Several variables can swing your final bill—sometimes by thousands. Here’s what matters most:

1. Type of Pipes Used

• PEX (cross-linked polyethylene): $0.40–$2.00/ft – flexible, freeze-resistant, easy to install. Most common in new builds.
• Copper: $2–$8/ft – durable but expensive and labor-intensive.
• PVC/CPVC: $0.50–$2/ft – used for drains and cold water; not for hot water (unless CPVC).

According to the U.S. Department of Energy , PEX is now the standard in over 60% of new U.S. homes due to cost and efficiency.

2. Home Layout & Accessibility

Homes with open walls (during construction) cost far less than retrofits. Installing plumbing in a finished basement or behind tile? Expect 20–50% higher labor costs.

3. Local Labor Rates

Plumbers in New York or San Francisco charge $100–$180/hour, while rural areas may be $60–$90/hour. Always get 3 local quotes.

4. Permits & Inspections

Most municipalities require plumbing permits ($50–$500). Skipping them risks fines or failed home inspections later.

5. Fixture Inclusion

Are toilets, sinks, and shower valves included? If yes, add $1,000–$5,000+ depending on quality.

DIY vs. Hiring a Pro: What’s Safer and Smarter?

You can install simple plumbing fixtures yourself—but full-system installation? Not recommended.

✅ Hire a Licensed Plumber If:

• You’re doing new construction or a full repipe
• Local codes require licensed work (most do)
• You lack experience with soldering, pressure testing, or venting

⚠️ Risks of DIY Plumbing:

• Leaks or bursts from improper joints
• Code violations that void insurance
• Voided warranties on water heaters or fixtures

The International Association of Certified Home Inspectors reports that 23% of plumbing-related insurance claims stem from amateur installations.

Step-by-Step: What Happens During Professional Plumbing Installation?

If you hire a pro, here’s what to expect:

1. Design & Permitting (1–3 days)
   The plumber reviews blueprints, selects materials, and files for permits.
2. Rough-In Phase (2–5 days)
   Pipes are run through walls, floors, and ceilings. Supply lines and DWV pipes are installed—but no fixtures yet.
3. Inspection (1 day)
   A city inspector checks for code compliance before walls are closed.
4. Finish Plumbing (1–3 days)
   Toilets, sinks, faucets, and water heater are connected.
5. Pressure & Leak Testing
   The system is pressurized with air or water for 15–30 minutes to detect leaks.
6. Final Walkthrough
   You test all fixtures and review warranty details.

📏 Example: In a 2,000 sq ft home using PEX, expect 1,200–1,800 linear feet of pipe, installed over 5–7 days by a 2-person crew.

Cost-Saving Tips Without Sacrificing Quality

• Bundle projects: Install plumbing during a kitchen/bath remodel to avoid duplicate labor.
• Choose PEX over copper: Saves 30–50% on materials.
• Get multiple quotes: Prices can vary by 40% between contractors.
• Ask about off-season discounts: Some plumbers offer 10–15% off in winter.
• Verify licenses & insurance: Avoid “handyman” deals that lack liability coverage.
