Thinking about starting a career in plumbing? You’re not alone—many people are drawn to the trade for its stability, hands-on work, and strong earning potential. But before you sign up for that first apprenticeship, you probably want to know: how much does a plumber apprentice make an hour? The answer isn’t one-size-fits-all, but we’ll break down the numbers, factors that affect pay, and what you can realistically expect as you begin your journey in the plumbing industry.
What Is a Plumber Apprentice?
A plumber apprentice is someone training to become a licensed plumber through a combination of on-the-job experience and classroom instruction. Most apprenticeships last 4 to 5 years, during which you’ll work under the supervision of a journeyman or master plumber while learning the technical and safety aspects of the trade.
Apprenticeships are typically sponsored by trade unions (like the United Association), plumbing contractors, or vocational schools. According to the U.S. Department of Labor, registered apprenticeships must meet specific standards for pay, training hours, and mentorship.
💡 Did You Know? Plumbing is one of the few skilled trades where you can earn while you learn—often with little to no student debt.
How Much Does a Plumber Apprentice Make an Hour? (2025 Data)
As of 2025, the average hourly wage for a plumbing apprentice in the United States ranges from $15 to $25 per hour, depending on location, employer, and year in the program.
Here’s a general breakdown by apprenticeship year:
| Year 1 | $15 – $18 |
| Year 2 | $17 – $20 |
| Year 3 | $19 – $22 |
| Year 4 | $21 – $24 |
| Year 5 | $23 – $25+ |
These wages typically increase annually as you gain skills and complete required classroom hours (usually 144–200 hours per year).
According to the Bureau of Labor Statistics (BLS), the median annual wage for all plumbers, pipefitters, and steamfitters was $60,090 in May 2023—meaning many journeymen earn over $30/hour. Apprentices start lower but see steady, predictable raises.
What Factors Affect a Plumbing Apprentice’s Pay?
Several key variables influence how much you’ll earn as an apprentice:
1. Geographic Location
Wages vary significantly by state and city due to cost of living and local demand. For example:
- California: $20–$26/hour (high cost of living, strong union presence)
- Texas: $16–$22/hour
- Ohio: $15–$19/hour
- New York: $22–$28/hour (especially in NYC)
Check your state’s Department of Labor website for registered apprenticeship wage scales.
2. Union vs. Non-Union Programs
Union apprentices (e.g., through UA Local unions) often start at higher wages and receive better benefits, including health insurance and retirement plans. Non-union programs may offer more flexibility but sometimes lower initial pay.
3. Employer Type
Large commercial plumbing contractors may pay more than small residential companies—especially if they handle high-volume or emergency service work.
4. Overtime & On-Call Work
Many plumbing apprentices earn time-and-a-half for overtime (common in emergency repairs or summer construction booms). Some also receive on-call pay for after-hours availability.
How Do Plumbing Apprenticeship Wages Compare to Other Trades?
Let’s put plumbing in context. Here’s how first-year apprentice wages stack up against similar skilled trades (2025 estimates):
| Plumbing Apprentice | $15 – $18 |
| Electrician Apprentice | $16 – $20 |
| HVAC Apprentice | $14 – $17 |
| Carpentry Apprentice | $15 – $19 |
While electricians often start slightly higher, plumbers tend to catch up—and surpass—by journeyman level due to high demand for water, gas, and sewer system expertise.
📌 Pro Tip: Plumbing offers strong long-term income growth. Many master plumbers run their own businesses and earn $70,000–$120,000+ annually.
Steps to Maximize Your Apprentice Earnings
Want to earn on the higher end of the scale? Follow these actionable steps:
- Join a Registered Apprenticeship Program
Programs approved by the U.S. Department of Labor or your state ensure fair wages and structured progression. Find one via Apprenticeship.gov . - Relocate to a High-Demand Area
States like Arizona, Florida, and Colorado are experiencing rapid construction growth—and plumbing shortages. Higher demand = better pay. - Complete Certifications Early
Earning OSHA 10, backflow prevention, or green plumbing certifications can make you more valuable—and eligible for premium assignments. - Track Your Hours Meticulously
Your wage increases are tied to completed on-the-job and classroom hours. Keep a log to ensure you’re paid correctly. - Ask About Benefits
Health insurance, 401(k) matches, and tool allowances can add $5–$10/hour in real value—even if your base wage seems modest.
Real-Life Example: Meet Jake, a 3rd-Year Apprentice in Denver
Jake, 22, started his plumbing apprenticeship in 2023 with a union contractor in Denver, CO.
- Year 1 wage: $18/hour
- Year 2 wage: $20.50/hour
- Current (Year 3): $22.75/hour + health insurance + pension contributions
He works 40–50 hours/week, often earning overtime during winter pipe-freezing emergencies. “I’m already making more than some of my college friends,” he says, “and I have zero student loans.”
Plumbing Apprenticeship Pay vs. College Debt
Consider this:
- The average U.S. college graduate leaves school with $37,000 in student debt (Federal Reserve, 2024).
- A plumbing apprentice earns $30,000–$45,000 in Year 1—with raises each year and no tuition debt.
By the time a college grad starts repaying loans, a plumber may already be a licensed journeyman earning $60,000+ with savings in the bank.

FAQ: Plumbing Apprentice Hourly Pay
Q1: Do plumbing apprentices get paid weekly or biweekly?
Most employers pay apprentices weekly or biweekly, just like full-time employees. Payment frequency depends on the company’s payroll system.

In registered apprenticeships, yes—classroom instruction is considered part of your paid work hours. You’ll typically attend school one night per week or in blocks.
Q5: What’s the highest-paying state for plumbing apprentices?
As of 2025, Alaska, Hawaii, Illinois, and New Jersey report the highest average apprentice wages—often exceeding $24/hour in later years due to union agreements and high living costs.

Rarely. Most programs use predetermined wage schedules based on collective bargaining or state guidelines. However, prior experience (e.g., military, construction) may qualify you for advanced entry.
Conclusion
So, how much does a plumber apprentice make an hour? Realistically, between $15 and $25, with steady increases as you gain skills and experience. While it may not sound like a fortune at first, remember: you’re getting paid to learn a high-demand, recession-resistant trade—with a clear path to $60K–$100K+ earnings in under five years.
