How much do plumbers make in Wisconsin in 2026?

The median plumber in Wisconsin earns $81,210 a year, which works out to roughly $39.04 an hour based on a standard 2,080-hour work year. That number comes from the Bureau of Labor Statistics Occupational Employment and Wage Statistics survey, May 2025. It covers journeymen and experienced plumbers across the state — not just entry-level hires and not just master plumbers running their own crews.

The spread across the pay scale is wide. At the 25th percentile, plumbers in Wisconsin earn $61,430 annually, or about $29.53 an hour. These are typically workers earlier in their careers, still building hours toward a journeyman or master license, or working in lower-wage corners of the state. At the 75th percentile, pay reaches $103,560 a year — roughly $49.79 an hour. Workers at that level usually have their master license, years of experience on complex commercial or industrial jobs, or are running a crew.

The gap between the 25th and 75th percentile is over $42,000 a year. That's not a rounding error — it reflects real differences in licensure, specialization, years on the job, and employer type. A plumber doing service work for a residential contractor in a small town earns a different wage than one working a large commercial build in the Milwaukee or Madison metro. Geography within Wisconsin matters. The Milwaukee metro and the Madison area tend to support higher wages than rural parts of the state simply because project volume is higher, more contractors compete for labor, and cost of living pulls wages up with it.

Wisconsin requires plumbers to be licensed through the Department of Safety and Professional Services. You need a licensed journeyman plumber credential to work independently, and a master plumber license to pull permits or run a plumbing business. Most workers get there through a formal apprenticeship — typically five years combining on-the-job hours with classroom instruction. During apprenticeship, pay is set as a percentage of journeyman scale, starting lower and stepping up year by year. By year four or five, apprentice pay is close to full journeyman rate.

Overtime is a real factor in what plumbers actually take home. The $81,210 median is based on regular straight-time wages. Many plumbers work well beyond 40 hours during busy seasons — spring through fall on new construction, or during emergency service calls year-round. At time-and-a-half, a plumber earning $39.04 an hour straight time earns $58.56 for every overtime hour. Ten hours of overtime a week for six months adds roughly $18,000 to $20,000 on top of base wages. The BLS figures don't fully capture that.

Some Wisconsin plumbers work under collective bargaining agreements. If you're covered by a union contract, your pay and benefit terms are set by that agreement — check your local's contract directly for the current wage schedule, because those rates can differ from the statewide BLS median in either direction. The BLS numbers blend union and non-union workers together.

Benefits also affect total compensation in ways the salary figures don't show. Health insurance, pension contributions, paid time off, and tool allowances vary significantly between employers. A plumber earning $78,000 with full health coverage and a pension is likely better compensated overall than one earning $85,000 with a bare-bones benefits package. When comparing job offers, ask about total compensation, not just the hourly rate.

To move up from the 25th percentile toward the median and beyond, the most direct levers are licensing and specialization. Getting your journeyman license, then your master license, is the baseline. After that, experience on medical gas systems, high-pressure piping, fire suppression, or large commercial hydronic systems commands premium pay. Plumbers who can read plans, estimate jobs, and manage small crews are worth more to employers than those who can only swing a wrench. Relocating to — or commuting into — a higher-wage metro area is another option that some workers use to close the gap.
