The Bureau of Labor Statistics Occupational Employment and Wage Statistics release covering Standard Occupational Classification 47-2152 — plumbers, pipefitters, and steamfitters — reports a national median wage of $30.85 per hour ($64,160 annually) for the most recent reporting year. That single number masks one of the widest geographic wage spreads in the construction trades. A master plumber in Anchorage runs better than $52 an hour at the BLS median; a residential service plumber outside Jacksonville sits closer to $23. The 2.3x spread between Alaska and Florida is larger than the geographic spread BLS reports for electricians, carpenters, or sheet metal workers.
What plumbers actually take home depends on four variables: state, NAICS sub-industry, union status, and license tier. Read those four levers correctly and the same nominal "$30.85 median" plumber resolves into compensation outcomes that range from $48,000 to north of $120,000 in fully loaded annual earnings.
Plumber Wages by State in 2026
BLS OES state data for SOC 47-2152 shows a wage distribution driven by union density, license reciprocity rules, and regional industrial concentrations. The top end is dominated by states with strong United Association (UA) locals and active industrial maintenance markets.
Top 10 highest-paying states (BLS state median hourly):
| Rank | State | Median Hourly | Annual (2,080 hrs) |
|---|---|---|---|
| 1 | Alaska | $52.39 | $108,971 |
| 2 | Illinois | $46.87 | $97,490 |
| 3 | Massachusetts | $45.21 | $94,037 |
| 4 | New York | $44.10 | $91,728 |
| 5 | New Jersey | $43.50 | $90,480 |
| 6 | Hawaii | $42.80 | $89,024 |
| 7 | Washington | $42.30 | $87,984 |
| 8 | Minnesota | $40.85 | $84,968 |
| 9 | Oregon | $40.20 | $83,616 |
| 10 | California | $39.60 | $82,368 |
Alaska's $52.39 median is driven by oil and gas industrial maintenance on the North Slope and Cook Inlet, plus the UA Local 367 wage scale that sets the floor for commercial mechanical work in Anchorage and Fairbanks. The same plumber doing residential repipe in Phoenix earns roughly half as much.
Lowest-paying states (BLS state median hourly): Florida ($23.10), South Carolina ($23.40), Arkansas ($23.80), Mississippi ($24.10), Tennessee ($24.50). Right-to-work statutes, weaker UA local density, and dominant residential-service mix suppress state medians. A Florida-licensed plumber who picks up a Massachusetts journeyman card through reciprocity can roughly double their rate without changing skill set.

What Construction Plumbers Earn vs the Broader Trade
The $30.85 all-industry median understates construction-employed plumber pay. NAICS 23 cross-tabulations from the same BLS release shift the median upward by $2 to $4 per hour — construction pays more than the all-industry blend because it competes against manufacturing maintenance, facilities operations, and municipal water utilities for the same workforce.
Construction-employed plumbers (NAICS 23) show a median of $33 to $35 per hour depending on the split between residential building (NAICS 2361), nonresidential building (NAICS 2362), and specialty trade plumbing contractors (NAICS 2382). The 75th percentile runs $43 to $46/hour and the 90th percentile clears $58/hour — that top decile is almost entirely commercial and industrial mechanical work in major metros.
The gap between residential service and commercial mechanical plumbing inside the same metro is wider than most outside the trade realize. A residential service plumber in Chicago running drain calls and water heater swaps earns $26 to $32/hour. A commercial mechanical journeyman running medical gas and process piping for a UA Local 130 signatory contractor earns total compensation above $80/hour. Same city, same trade title, fundamentally different pay.

Union vs Non-Union: The Real $14/Hour Spread
The United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry — the UA — is the dominant union for commercial and industrial plumbing. UA Local 130 in Chicago publishes a 2026 journeyman plumber rate of $54.85/hour base wage plus a package value of approximately $38/hour (pension, health and welfare, annuity, training, supplemental pension) for total compensation above $92/hour to the employer.
A non-union plumber of comparable skill in the same Chicago commercial market runs $40 to $48 per hour total compensation including employer benefits — a gap of roughly $44/hour on total compensation, or $14/hour on base wage alone.
The differential is geographically concentrated. In non-RTW states with strong UA presence (Illinois, New York, Massachusetts, New Jersey, Minnesota, Washington), the wage gap on commercial work runs 25 to 35% on base wage and more on total compensation. In RTW states (Texas, Florida, Tennessee, Georgia, the Carolinas), the gap compresses to 8 to 15% because non-union contractors must offer competitive benefits to retain skilled workers. In non-RTW states the union local controls the apprenticeship pipeline and thus the labor supply; in RTW states multiple non-union training routes (community college, ABC apprenticeship, in-house) compete with the UA pipeline.
Safety note: OSHA 29 CFR 1926.651 governs trenching and excavation safety for plumbers running underground service lines and sewer laterals. Per BLS Survey of Occupational Injuries and Illnesses data, trench cave-ins remain the highest-fatality exposure in residential and light commercial plumbing — protective systems (sloping, shoring, shielding) are required for any excavation 5 feet or deeper unless the excavation is in stable rock. Soldering and brazing exposures (lead, flux fumes, hex-chrome on stainless work) fall under the OSHA construction hex-chrome standard at 29 CFR 1926.1126. Wage levels should be evaluated alongside the regulatory framework that governs the work.
Apprentice to Journeyman to Master: Where the Money Hides
The plumber wage curve is one of the steepest in construction, and most of the steepness lives in the back half. The license tier — apprentice, journeyman, master — is the single biggest pay lever a plumber controls.
Apprentice plumber (Years 1-5): UA joint apprenticeship programs and state-registered apprenticeships start first-year apprentices at 40 to 50% of journeyman scale. In a market where journeyman scale is $40/hour, a first-year apprentice earns $18 to $22/hour with raises every six months tied to verified on-the-job training (typically 2,000 OJT hours per year) plus 144 hours of related classroom instruction. By Year 5 the apprentice approaches 90 to 95% of journeyman scale. The apprentice route is debt-free — UA apprentices pay no tuition; the trust fund covers all classroom instruction.
Journeyman plumber (Years 5+): The journeyman card is the threshold to full-scale work. National median journeyman base wage runs $30 to $50/hour depending on market and union status. Journeymen can sign for and warranty their own work in most jurisdictions but cannot pull permits as the responsible licensed master.
Master plumber: Master licensure requires 2 to 4 years of post-journeyman experience plus a written exam covering code, theory, and business practice. The license carries the right to pull permits, sign off on plans, and operate as a responsible plumbing contractor. Master commands a $5 to $10/hour premium over journeyman scale in the field and substantially more when operating as contractor of record. Once earned, the master license does not need to be re-tested in most states (continuing education only).

Specialty Certifications That Pay Extra
Certifications stacked on top of the base license are where journeymen and masters add $3 to $12/hour without changing employers.
Medical gas installer (ASSE 6010) and verifier (ASSE 6020): Med gas piping for hospitals, surgery centers, and outpatient surgical facilities is governed by NFPA 99 and requires certified installers plus a separate certified verifier for acceptance testing. Med-gas-certified plumbers command a $4 to $8/hour premium on healthcare projects. Certification requires brazing qualification under ASME Section IX BPVC plus a written exam through an ANSI-accredited body.
Backflow prevention tester (ASSE 5110 / state-specific): Municipal water authorities require annual testing of reduced-pressure backflow assemblies, double-check valves, and pressure vacuum breakers protecting potable water from commercial cross-connections. An independent backflow tester bills $80 to $200 per assembly; employed testers earn a $3 to $5/hour premium over journeyman scale.
Hydronic heating (Radiant Professionals Alliance / IAPMO): Hydronic radiant heating, snowmelt, and chilled-beam systems require knowledge beyond conventional plumbing training. Hydronic-certified plumbers command a $4 to $7/hour premium in northern-tier markets where radiant floor heating is standard and snowmelt is required for hospital and commercial entrances.
Fuel gas piping (NFPA 54 / state mechanical endorsement): Most states require a separate endorsement for natural gas and propane piping. The endorsement adds $2 to $4/hour for plumbers working residential service and commercial mechanical with gas appliance connections.
Pipefitters and Steamfitters: The Industrial Premium
BLS classifies plumbers, pipefitters, and steamfitters under the same SOC code (47-2152), but the industrial side — process piping, high-pressure steam, refinery and petrochemical maintenance — runs $4 to $8/hour higher than commercial plumbing in the same metro.
UA-organized industrial pipefitting commonly pays $48 to $60/hour base wage plus package value above $30/hour. Refinery turnaround work pulls per-diem of $100 to $175/day plus 1.5x overtime for the duration. A pipefitter working a 60-hour turnaround week routinely clears $4,500 to $5,500 weekly including per-diem, and travels seven to ten weeks a year on rotational turnaround schedules.
Skill overlap is partial — pipefitters carry brazing, welding, and threading that overlaps with plumbing, plus pressure-piping fabrication and rigging that commercial plumbers typically do not. Plumbers who cross-train into pipefitting through UA apprenticeship typically earn back the additional training time within two years.
Why the Plumber Shortage Is Structural
BLS projects plumber, pipefitter, and steamfitter employment to grow 6% from 2024 to 2034, compared to 4% for all occupations. The growth rate is solid but not extraordinary. The shortage is severe anyway, because the supply pipeline is broken.
- Median age of working plumbers: approximately 47 years, per ACS occupational tabulations — older than the median construction worker (42) and older than the median electrician (44).
- Annual replacement need: roughly 42,600 openings per year combining growth and retirement.
- Annual training program completions (apprenticeship, community college, technical school combined): approximately 23,000 to 27,000.
The annual gap of 15,000 to 19,000 trained plumbers per year compounds. DOL RAPIDS data shows roughly 52,000 active plumber apprentices against a total workforce of approximately 482,000. The replacement ratio is structurally inadequate against current attrition.
The cultural factor compounds the structural one. A generation of high-school guidance counselors directed academically capable young adults toward four-year college and away from trades apprenticeships. The result is a labor market in which a 25-year-old UA journeyman plumber in Chicago is earning more in wages plus benefits than the median holder of a bachelor's degree at the same age, with zero student debt — and the industry still cannot fill licensed positions. The apprenticeship pipeline takes five years to deliver a journeyman, and the supply gap is compounding faster than enrollment is expanding. Plumber wages will continue to outrun general wage growth through the end of the decade.
Frequently Asked Questions
What is the average hourly wage for a plumber in 2026?
BLS Occupational Employment and Wage Statistics data for SOC 47-2152 (plumbers, pipefitters, and steamfitters) reports a national median wage of $30.85 per hour ($64,160 annually) for the most recent reporting year. Construction-employed plumbers (NAICS 23 cross-tab) earn a median of approximately $33 to $35 per hour, $2 to $4 higher than the all-industry median, because the construction sector competes against manufacturing maintenance, facilities operations, and municipal water utilities for the same skilled workforce.
Which states pay plumbers the most?
BLS state-median data ranks Alaska first at $52.39/hour, followed by Illinois ($46.87), Massachusetts ($45.21), New York ($44.10), New Jersey ($43.50), Hawaii ($42.80), Washington ($42.30), Minnesota ($40.85), Oregon ($40.20), and California ($39.60). Top-paying states share two structural features: strong United Association local density (which sets a wage floor through collective bargaining) and active industrial maintenance markets (oil and gas in Alaska, petrochemical and refining in Illinois and Washington, biotech and pharma in Massachusetts and New Jersey).
How much does a union plumber make compared to non-union?
In non-right-to-work states with strong UA presence (Illinois, New York, Massachusetts, New Jersey, Minnesota, Washington), union journeyman plumbers earn 25 to 35% more in base wages than non-union counterparts and substantially more in total compensation when pension and benefit contributions are included. UA Local 130 in Chicago publishes a 2026 journeyman base rate of $54.85/hour plus approximately $38/hour in package value (pension, health, annuity, training) for total compensation above $92/hour to the employer. In right-to-work states, the union/non-union differential compresses to 8 to 15% because non-union contractors compete on benefit packages to retain skilled workers.
What does a master plumber license add to earnings?
Master plumber licensure requires 2 to 4 years of post-journeyman experience in most states plus a written exam, and commands a $5 to $10/hour premium over journeyman scale when working in the field. The bigger income lever is the right to pull permits and operate as a responsible plumbing contractor — a licensed master plumber operating as a contractor of record earns substantially more than scale, particularly on residential service and small commercial work. Most states require continuing education to renew the master license, but the license itself does not need to be re-tested.
Which plumber specialty certifications pay the most?
The largest single specialty premium is medical gas certification (ASSE 6010 installer / ASSE 6020 verifier) at $4 to $8/hour above journeyman scale on healthcare projects. Backflow prevention testing adds $3 to $5/hour and supports an independent service revenue stream (typical billing $80 to $200 per assembly tested annually). Hydronic heating adds $4 to $7/hour in northern-tier markets where radiant floor and snowmelt systems are standard. Fuel gas endorsement adds $2 to $4/hour and is a regulatory requirement in most states for any plumber working with natural gas or propane piping.
Is there a shortage of plumbers in 2026?
Yes, structurally. The median age of working plumbers is approximately 47 years and retirements are accelerating. BLS projects 6% employment growth from 2024 to 2034 against an annual replacement need of roughly 42,600 openings per year. Annual completion of plumbing training programs (registered apprenticeship, community college, technical school combined) runs 23,000 to 27,000, producing a recurring annual gap of 15,000 to 19,000 trained plumbers that compounds against a total workforce of approximately 482,000. The shortage is the primary reason plumber wages are outrunning general wage growth, and it will not resolve in one to two years — the apprenticeship pipeline takes five years to deliver a journeyman.
What is the apprentice plumber starting wage?
UA joint apprenticeship programs and most state-registered apprenticeships start first-year apprentices at 40 to 50% of journeyman scale in their market. In a market where journeyman scale is $40/hour, a first-year apprentice earns $18 to $22 per hour with structured raises every six months tied to verified on-the-job training hours and 144 hours of annual classroom instruction. By Year 5 the apprentice approaches 90 to 95% of full journeyman scale. UA apprentices pay no tuition — the apprenticeship trust fund covers all classroom instruction, making the apprenticeship route a debt-free path to a journeyman card.
