Average Cost to Put In Plumbing for 1-Bedroom Apartment

Thinking about installing new plumbing in a 1-bedroom apartment? Whether you’re renovating an old unit, building from scratch, or converting a space into livable housing, understanding the average cost to put in plumbing for a 1-bedroom apartment is essential for smart budgeting. Plumbing is one of the most critical—and expensive—parts of any residential project, and costs can vary widely based on location, materials, and labor. Let’s break it all down so you’re never caught off guard.

What Is the Average Cost to Install Plumbing in a 1-Bedroom Apartment?

On average, the average cost to put in plumbing for a 1-bedroom apartment ranges from $4,000 to $10,000 in the United States as of 2025. This estimate includes rough-in plumbing (pipes, drains, vents) and finish work (fixtures, faucets, water heater connections).

According to HomeAdvisor’s 2024 Cost Guide, plumbing installation for a 600–800 sq ft unit (typical for 1-bedroom apartments) costs $6–$12 per square foot, depending on complexity. In high-cost areas like New York City or San Francisco, you might pay closer to $12,000–$15,000, while rural or low-demand regions could see totals as low as $3,500.

💡 Pro Tip: Labor typically accounts for 60–70% of total plumbing costs. Materials make up the rest—but skimping on quality can lead to leaks, code violations, or costly repairs later.

What Factors Influence Plumbing Installation Costs?

Several key variables affect your final bill. Here’s what to consider:

1. Location

Labor rates differ drastically by region. Urban centers command higher wages for licensed plumbers. For example:

• Texas: $4,000–$7,000
• California: $8,000–$14,000
• Midwest: $3,800–$6,500

2. Type of Plumbing System

• New construction: Easier access, lower cost (roughly $4,000–$7,000)
• Retrofit in existing building: Walls must be opened, increasing labor ($7,000–$12,000+)

3. Materials Used

📌 Note: The U.S. Environmental Protection Agency (EPA) and local building codes often dictate which materials are permitted. Always consult your local authority or a licensed plumber before choosing.

4. Number of Fixtures

A standard 1-bedroom apartment typically includes:

• 1 kitchen sink
• 1 bathroom (toilet, sink, shower/tub)
• 1 washing machine hook-up (optional)

Each additional fixture adds $300–$800 in materials and labor.

Step-by-Step: How Plumbing Installation Works in a 1-Bedroom Unit

If you’re planning new plumbing, here’s what the process usually looks like:

1. Design & Permits (1–3 days)
   • Work with a plumber or engineer to draft a plumbing layout.
   • Submit plans to your local building department. Permit fees: $100–$500.
2. Rough-In Phase (2–5 days)
   • Install water supply lines (hot/cold), drain-waste-vent (DWV) pipes, and stub-outs for fixtures.
   • Use ¾-inch PEX for main supply lines and ½-inch for branch lines.
   • Ensure proper slope (¼ inch per foot) for drain pipes to prevent clogs.
3. Inspection (1 day)
   • Local inspector checks code compliance before walls are closed.
   • Common failure points: improper venting, missing shut-off valves.
4. Fixture Installation (1–2 days)
   • Mount toilets, sinks, faucets, shower valves.
   • Connect water heater (if not shared).
   • Test all lines for leaks at 60–80 PSI for 15 minutes.
5. Final Walkthrough & Certification
   • Plumber provides as-built drawings and warranty info (typically 1 year on labor).

🔧 Safety First: Always hire a licensed, insured plumber. According to the Bureau of Labor Statistics, unlicensed work causes 22% of plumbing-related insurance claims.
