Plumber Salary in Wisconsin 2026,
$81,210 Median | BLS Data by City

The published figure is $81,210 a year, or $39.04 an hour, per BLS OEWS May 2025, on SOC 47-2152 — Plumbers, Pipefitters and Steamfitters, a row broader than plumbing alone. The band runs from $50,020 at the 10th percentile to $120,070 at the 90th, and the state figure sits 27.3% above the national median of $63,800.

Eau Claire, at $92,720, then Appleton $91,750, Sheboygan $91,530, Green Bay $90,570 and Wausau $86,750. Milwaukee-Waukesha does not appear in the published top five, which is the clearest possible signal that this row is being driven by industrial pipefitting in the Fox Valley, the lakeshore and western Wisconsin rather than by metropolitan construction.

Through the Department of Safety and Professional Services Plumbing Program. Register as an apprentice, complete supervised hours and related instruction, then sit the journeyman examination; the master plumber licence sits above that and allows responsibility for a business's plumbing work. Wisconsin administers its own plumbing code, so the examination tests state-specific rules rather than a model code alone.

Three reasons stack. Wisconsin licenses individual plumbers rather than only contractors, which constrains supply; the SOC row includes industrial pipefitting and steamfitting, which pays well above residential service; and the state's manufacturing base — food and dairy processing, paper, foundries and machinery — generates steady process-piping and shutdown work at a location quotient of 1.16 across 10,210 jobs.

Mostly the type of work rather than years served. The $50,020 to $61,430 lower quartile is apprentice and entry service work; the $103,560 seventy-fifth percentile and the $120,070 ninetieth are industrial pipefitters, welders on process piping, foremen and master-licensed plumbers. Moving between those two populations is a deliberate career choice, not an automatic progression.

Plumbers, pipefitters and steamfitters together, which in this state means two quite different labour markets on one row. Residential and commercial plumbing follows the housing and building cycle and is priced against a competitive contractor market. Industrial pipefitting and steamfitting follows manufacturing capital and maintenance spending, requires welding qualifications and process-piping experience, and is paid at rates that reflect scarcity plus the unsocial hours of shutdown schedules. Wisconsin's manufacturing intensity means the second group is a large share of the row here, which is why the state median exceeds the national one by 27.3% and why the band is as wide as it is.

It is straight-time and it excludes the self-employed. BLS reports base earnings, so the overtime attached to plant shutdowns and outages — a defining feature of Wisconsin industrial pipework and heavily concentrated into a few weeks of the year — sits entirely outside it. Master-licensed plumbers who start their own businesses also leave the row, so the $120,070 ninetieth percentile describes the top of the employed population rather than the top of the trade. And it is not a plumber-only figure, which matters most for anyone benchmarking a residential service job.

In the plants, not the metros. Eau Claire $92,720, Appleton $91,750, Sheboygan $91,530, Green Bay $90,570 and Wausau $86,750 are all markets built around processing, paper and machinery manufacturing. The work that pays is process piping, sanitary and food-grade welding, boiler and steam systems, and the annual outage schedules those plants run. Add per diem on travelling maintenance work and a shift differential on plant assignments, none of which appears in a straight-time median, and the practical earnings gap between residential service and industrial pipefitting in this state is larger than the published band suggests.
