Plumbing is one of the most recession-resistant skilled trades in the United States. New construction slows and speeds with the housing market, but service and repair plumbing is a steady-state demand - every home, every commercial building, every industrial facility needs plumbing maintenance and emergency repair. With a national median wage that has climbed past $63,000 and a 4.5% projected growth rate through 2034, plumbing remains a reliable career path. This guide uses BLS Occupational Employment and Wage Statistics released for May 2025 to map plumber pay across the country, then layers in the apprenticeship pathway, the journeyman-to-master licensing premium, and the union-versus-non-union pay gap.
If you are evaluating a plumbing career, comparing apprenticeship programs, or negotiating your first journeyman offer, the numbers below give you the working baseline. We have also broken out the top-paying metros, the highest-paying industries for plumbers, and the licenses that raise plumber income most.

What is the national plumber salary in 2026? Plumbers earn a national median of $63,800, with the top decile clearing $108,420.
The BLS OEWS May 2025 release pegs the national median plumber wage at $63,800 per year, with the 10th percentile at $44,150 and the 90th percentile at $108,420 (Source: BLS OEWS May 2025, occupation code 47-2152). National employment of plumbers sits at roughly 426,000 (Source: BLS OEWS, May 2025).
The 90/10 spread of $64,000 reflects the gap between apprentice and master plumber pay. Apprentices in the first year typically earn $18-$23 per hour. Journeyman plumbers cluster at the median. Master plumbers and plumbing contractors clear the 90th percentile, with strong six-figure income in commercial and industrial work.
Plumber apprenticeship is a four to five year program combining paid on-the-job training (8,000-10,000 hours) with classroom instruction (600+ hours). Apprentices earn wages from day one, starting at 40-60% of journeyman scale and graduating to full pay on completion (Source: BLS OOH Plumbers, 2025).
Which states pay plumbers the most in 2026? Illinois, Oregon, and Minnesota lead on mean annual plumber pay, with Wisconsin and New York close behind.
Top states by mean annual wage for plumbers (Source: BLS OEWS May 2025):
| Rank | State | Mean Annual Wage |
|---|---|---|
| 1 | Illinois | $96,200 |
| 2 | Oregon | $93,110 |
| 3 | Minnesota | $83,280 |
| 4 | Wisconsin | $78,510 |
| 5 | New York | $78,460 |
| 6 | Massachusetts | $77,920 |
| 7 | Connecticut | $76,830 |
| 8 | Washington | $76,210 |
| 9 | Alaska | $75,840 |
| 10 | California | $74,310 |
Illinois tops plumber pay at $96,200 mean - driven by Chicago's strong UA Local 130 union presence and high commercial-construction volume. Oregon follows at $93,110, with Minnesota in third at $83,280. The Midwest dominates the top of the chart, reflecting strong union density and consistent commercial-construction work.
Which states pay plumbers the least in 2026? The lowest-paying states cluster in the Southeast, with Mississippi and West Virginia at the bottom.
Bottom states by mean annual wage for plumbers (Source: BLS OEWS May 2025):
| State | Mean Annual Wage | Hourly Mean |
|---|---|---|
| Mississippi | $46,210 | $22.22 |
| West Virginia | $47,940 | $23.05 |
| Arkansas | $48,820 | $23.47 |
| South Dakota | $49,310 | $23.71 |
| Montana | $50,490 | $24.27 |
| North Dakota | $51,210 | $24.62 |
| Alabama | $51,940 | $24.97 |
| Louisiana | $52,820 | $25.39 |
| Kentucky | $53,310 | $25.63 |
| Wyoming | $53,940 | $25.93 |
The bottom of the plumber pay scale clusters in the $46K-$54K mean range. The gap between the top state (Illinois $96,200) and bottom state (Mississippi $46,210) is roughly $50,000 - about a 108% spread. Cost-of-living adjustment narrows this gap somewhat, but the structural wage differential between union-strong Midwest markets and non-union Southeast markets is the largest single factor.
What are the highest-paying metros for plumbers? Chicago and West Coast metros top plumber pay, with strong union presence driving the top of the list.
Top 10 metropolitan areas by mean annual wage for plumbers (Source: BLS OEWS May 2025 metro estimates):
| Metro Area | Mean Annual Wage |
|---|---|
| Chicago-Naperville-Elgin, IL-IN-WI | $104,820 |
| San Francisco-Oakland-Fremont, CA | $98,940 |
| Portland-Vancouver-Hillsboro, OR-WA | $96,710 |
| Seattle-Tacoma-Bellevue, WA | $93,820 |
| Boston-Cambridge-Newton, MA-NH | $89,310 |
| Minneapolis-St Paul-Bloomington, MN-WI | $87,940 |
| New York-Newark-Jersey City, NY-NJ-PA | $86,210 |
| Los Angeles-Long Beach-Anaheim, CA | $84,930 |
| Milwaukee-Waukesha-West Allis, WI | $83,420 |
| Hartford-East Hartford-Middletown, CT | $81,710 |
Chicago tops metro plumber pay at $104,820 mean - well above the national mean - driven by UA Local 130's strong union scale. San Francisco, Portland, and Seattle round out the top four. All top-10 metros have above-average union density or above-average cost-of-living adjustment.
How much more does a master plumber earn than a journeyman? Master plumbers typically earn 15-25% above journeyman pay, with the largest premiums in commercial work.
The journeyman-to-master plumber pay step is one of the largest wage jumps in the skilled trades. Master plumbers, who can pull permits, supervise crews, and run their own contracting businesses, typically earn 15-25% above journeyman wages (Source: UA Local Union wage data, 2025).
The premium stacks higher in commercial and industrial settings, where master plumbers move into foreman, general foreman, and project-superintendent roles. The premium is smallest in residential service work, where journeyman productivity and customer relationships often outpace master credentials on revenue.
For a plumber evaluating the master license, the math is straightforward: the four-year apprenticeship + 2-4 year journeyman phase + master exam = 6-8 years to top-of-scale pay. In UA markets, the journeyman-to-master step typically moves total comp from $80K-$95K to $100K-$130K depending on hours and overtime.
How much more do union plumbers earn? United Association (UA) union plumbers typically earn 20-30% above non-union pay, with stronger benefits and pensions.
The union-versus-non-union pay gap in plumbing work is one of the widest in the skilled trades. UA Local unions negotiate wages, benefits, and pensions through collective bargaining with mechanical-contractor associations. The negotiated wage scales run 20-30% above non-union pay in the same metro (Source: UA, 2025).
Beyond base pay, UA members typically receive employer-paid health insurance, defined-benefit pension contributions (often $4-$8/hour worked), and access to apprenticeship training that non-union employers struggle to match. The trade-off: UA employment follows work availability, with periodic layoffs during commercial-construction slowdowns.
For new apprentices, joining a UA apprenticeship program typically costs nothing - the program is funded by mechanical-contractor contributions - and provides structured classroom instruction, paid OJT hours, and direct path to journeyman licensure. The application process is competitive in dense metros.
Is plumber demand growing in 2026? Plumber employment is projected to grow 4.5% from 2024 to 2034, with about 44,000 openings per year.
BLS OOH projects plumber employment to grow 4.5% from 2024 to 2034, about in line with the 3.1% all-occupations baseline (Source: BLS OOH, 2024-34). About 44,000 openings are projected per year from growth, occupational transfers, and labor-force exits.
The growth drivers are well established. Aging housing stock requires more service and replacement work - the average U.S. home is now 40+ years old, with plumbing systems reaching end-of-life replacement windows. Water-efficiency regulations are driving fixture and pipe upgrades. And the labor supply is constrained: the average plumber is over 45, and apprenticeship completion rates have not kept pace with retirement.
Service and repair work - the largest employer segment - is less cyclical than new construction. Plumbing remains one of the more recession-resistant skilled trades, with steady demand through housing downturns.
What industries pay plumbers the most? Utility, manufacturing, and government employers top the industry pay list for plumbers.
BLS OEWS breaks plumber pay down by industry of employment. Mean annual wages by industry (Source: BLS OEWS May 2025):
| Industry | Mean Annual Wage | vs National Mean |
|---|---|---|
| Electric power generation, transmission, and distribution | $89,940 | +41% |
| Natural gas distribution | $85,210 | +34% |
| Federal executive branch | $82,930 | +30% |
| Petroleum and coal products manufacturing | $80,210 | +26% |
| Chemical manufacturing | $77,940 | +22% |
| Semiconductor and electronic component manufacturing | $74,820 | +17% |
| Nonresidential building construction | $66,940 | +5% |
| Plumbing and HVAC contractors | $61,210 | -4% |
| Residential building construction | $52,820 | -17% |
Utility plumbers and pipefitters earn the highest industry mean at $89,940 - driven by specialized high-pressure training and overtime-heavy on-call rotations. Federal government follows at $82,930, with strong benefits and pension contributions. Residential construction pays the lowest industry mean at $52,820 - the entry point for many new apprentices.
How should a plumber compare job offers? Compare on base wage + benefits + pension + schedule + overtime opportunity, not just headline pay.
Two plumber offers can look identical on hourly wage and differ by $20K+ in annual take-home. Build the comparison on six columns: base hourly wage, health insurance premium and deductible structure, retirement plan (401(k) match versus defined-benefit pension), overtime availability and premium rates, schedule stability, and continuing-education or licensing-cost support.
For union (UA) offers, the pension contribution is often the most underweighted column. A UA pension that contributes $5/hour worked - typical of strong locals - over a 30-year career accumulates to $400K+ in present-value retirement income. Always ask for the local's pension contribution rate before comparing.
For non-union offers, overtime availability is the swing variable. A $32/hour non-union residential role with cap on overtime can fall behind a $28/hour commercial role with unlimited OT at 1.5x. Always ask about the employer's typical weekly hours and seasonal overtime pattern.
