Thinking about a career as a plumber—but unsure how long it’ll take to get there? You’re not alone. Many Americans are drawn to plumbing for its steady demand, strong wages, and low student debt—but they get stuck on one key question: How long is school to be a plumber?
Good news: Becoming a licensed plumber doesn’t require a 4-year college degree. In fact, most plumbers enter the field in 2 to 5 years, combining hands-on training with classroom learning. In this guide, we’ll break down exactly how long school lasts, what training looks like, and how you can start sooner than you think.
How Long Does It Take to Become a Plumber in the U.S.?
The total time to become a licensed plumber typically ranges from 2 to 5 years, depending on your path and state requirements. Unlike traditional college degrees, plumbing training emphasizes apprenticeships—paid, on-the-job experience under a master plumber—paired with technical coursework.
According to the U.S. Bureau of Labor Statistics (BLS), most plumbing apprenticeships last 4 to 5 years, with 144–200 hours of classroom instruction and 2,000 hours of paid fieldwork each year.
💡 Pro Tip: Some states (like Texas or Florida) offer accelerated programs, while others (like New York or California) have stricter licensing rules—so location matters.
Do You Need to Go to School to Be a Plumber?
Yes—but not in the traditional sense. You won’t need a bachelor’s degree. Instead, you’ll likely attend a vocational school, trade school, or community college for plumbing fundamentals before or during your apprenticeship.
These programs usually last:
- Certificate programs: 6–12 months
- Associate degree (optional): 2 years
Subjects include:
- Pipe system design
- Local plumbing codes
- Blueprint reading
- Safety protocols
- Water distribution systems
Once enrolled, you’ll often apply for an apprenticeship simultaneously—many schools partner with local unions or contractors to place students directly into paid roles.
What’s the Typical Path to Becoming a Licensed Plumber?
Here’s a step-by-step roadmap most U.S. plumbers follow:
- Earn a High School Diploma or GED
Focus on math, physics, and shop classes—they build foundational skills. - Enroll in a Plumbing Program (Optional but Recommended)
A 6–12 month certificate program can help you stand out when applying for apprenticeships. - Apply for a Registered Apprenticeship
Find programs through:- United Association (UA)
- Home Builders Institute (HBI)
- Local unions or contractors
- Complete 4–5 Years of Apprenticeship
You’ll work full-time while attending night or weekend classes. You’ll be paid—starting at $18–$25/hour, with raises as you progress. - Pass Your State Licensing Exam
After your apprenticeship, you become a journeyman plumber. Later, you can pursue master plumber status (requires 2+ additional years of experience).
📊 Stat: The BLS reports that employment of plumbers is projected to grow 5% from 2022 to 2032—faster than average—thanks to aging infrastructure and new construction.
Trade School vs. Apprenticeship: Which Is Faster?
Many assume you must choose one—but most successful plumbers do both. Here’s how they compare:
| Feature | Trade School Only | Apprenticeship (with School) |
|---|---|---|
| Duration | 6–24 months | 4–5 years |
| Cost | $1,000–$15,000 | Often $0 (paid while learning) |
| Hands-on Experience | Limited | 8,000–10,000 hours |
| Job Placement | Varies | High (often guaranteed) |
| Licensing Readiness | Partial | Full |
Verdict: While trade school gives you a head start, apprenticeships are the gold standard—they’re paid, comprehensive, and directly aligned with licensing requirements.

How Much Does Plumbing School Cost?
Costs vary widely—but far less than a 4-year degree:
- Trade school certificate: $1,000–$15,000
- Community college (associate degree): $5,000–$20,000
- Apprenticeship tuition: Often free (sponsored by unions or employers)
Many apprenticeships even cover your tools, books, and exam fees. Plus, you earn a paycheck from Day 1.
💬 Expert Insight:
“Apprenticeships are the smartest entry point,” says Mark McElroy, Executive Director of the Plumbing-Heating-Cooling Contractors Association (PHCC). “You avoid debt, gain real-world skills, and build a professional network—all while getting paid.”
Can You Become a Plumber Without School?
Technically, yes—in some states. A few allow you to skip formal school and go straight into an apprenticeship if you pass a basic skills test. However, most states require at least some classroom hours to sit for the licensing exam.
Even if not required, skipping school puts you at a disadvantage:
- You’ll struggle with code exams
- Employers prefer trained candidates
- Safety risks increase without foundational knowledge
Bottom line: A few months of school can save you months (or years) of trial and error.
State-by-State Differences in Training Time
Plumbing licensing is state-regulated, so timelines vary. Examples:
- Texas: 4 years apprenticeship + exam → Journeyman license
- California: 4+ years + 700+ classroom hours
- Florida: 4 years + state exam (no formal school required, but recommended)
- New York: 4–5 years + local union requirements
Always check your state’s plumbing board website before enrolling in any program.
FAQ: Common Questions About Plumbing School
Q1: How long is school to be a plumber if I already have construction experience?
A: Prior experience may shorten your apprenticeship. Some states grant credit for related work (e.g., pipefitting or HVAC), potentially reducing training by 6–12 months.
Q2: Can I become a plumber at age 40 or older?
A: Absolutely! Plumbing welcomes career-changers. Many apprentices are in their 30s, 40s, or even 50s. Physical fitness matters more than age.
Q3: Do online plumbing courses count toward licensing?
A: Rarely. Most states require in-person, hands-on training. Online courses can supplement learning but won’t replace apprenticeship hours.
Q4: What’s the average salary for a plumber in the U.S.?
A: The BLS reports a median annual wage of $60,090 (as of May 2023). Top earners (master plumbers, business owners) can make $100,000+.
Q5: Is plumbing school hard?
A: It’s challenging but manageable. You’ll need basic math, problem-solving skills, and comfort with tools. Most students succeed with consistent effort.
Q6: How soon can I start working as a plumber?
A: You can begin your apprenticeship—and earn a paycheck—within 1–3 months of applying, especially if you’ve completed a short prep course.
Conclusion
So, how long is school to be a plumber? While classroom training typically lasts 6–24 months, the full path to licensing takes 2–5 years, mostly through paid apprenticeships. Compared to a $100,000+ college degree, plumbing offers a faster, debt-free route to a recession-proof career with strong earning potential.
Whether you’re a high school grad, a military veteran, or a career switcher, the pipes are open—and opportunity is flowing.
