Idaho Plumber Salary Overview
According to the U.S. Bureau of Labor Statistics, the national median annual wage for plumbers, pipefitters, and steamfitters is approximately $61,550. Idaho plumber wages are broadly competitive with the national median, and in the Treasure Valley the combination of high construction volume and reported labor shortages tends to push wages above national figures. Experienced journeyman plumbers in the Boise metro area can command $62,000 to $72,000 per year.
Idaho's plumbing market benefits from multiple demand drivers: residential development in the Treasure Valley and other growing communities, commercial and industrial construction, aging infrastructure in established neighborhoods requiring service and replacement, and specialized mechanical systems at data centers and technology facilities.
Idaho Plumber Salary by Experience Level
Apprentice Plumbers (Years 1-4)
Plumbing apprentices in Idaho typically earn $16 to $22 per hour in their first year, translating to roughly $33,000 to $46,000 annually. Wages increase with each year of the four-year apprenticeship. By the fourth year, apprentices are approaching journeyman wages and gaining proficiency in the full range of residential and commercial plumbing work.
Apprenticeship programs through the United Association (UA) plumbing locals and the Plumbing-Heating-Cooling Contractors Association (PHCC) provide structured training that combines on-the-job hours with classroom instruction in plumbing codes, blueprint reading, pipe sizing, and drain-waste-vent systems. Idaho technical colleges also offer plumbing programs that can serve as a foundation for apprenticeship applications.
Journeyman Plumbers
Licensed journeyman plumbers in Idaho earn $54,000 to $70,000 per year. The BLS Mountain division data confirms that plumber wages in the region are at or near the national median, with the Treasure Valley pulling wages above average due to construction volume. Journeymen working for larger commercial contractors or in industrial settings earn toward the higher end of this range, while residential service plumbers may earn slightly less in base wages but supplement income through service call premiums and overtime.
Idaho's journeyman plumber license is administered by the Idaho Division of Building Safety and requires completing an apprenticeship or equivalent training hours plus passing a licensing examination. Licensed journeymen are in genuine short supply in Idaho's fastest-growing markets.
Master Plumbers
Master plumbers in Idaho who operate plumbing contracting businesses earn $75,000 to $110,000 or more depending on business size and client mix. A master plumber license is required to pull permits and operate a plumbing contracting business in Idaho. Masters who build commercial service contracts or serve production homebuilders can generate strong recurring income. Independent master plumbers with established service territories report annual incomes of $90,000 to $130,000.

Plumbing Industries in Idaho
Residential New Construction
Residential new construction is the dominant driver of plumbing employment in Idaho. Rough-in plumbing for new homes, installing water heaters, setting fixtures, and connecting to municipal water and sewer systems keeps residential plumbers fully employed. High-volume production homebuilders offer steady employment, often with piece-rate pay structures that allow skilled workers to earn above hourly rates.
Commercial Plumbing
Commercial plumbing in Idaho involves complex systems in office buildings, retail centers, restaurants, hotels, and healthcare facilities. Commercial journeyman plumbers earn more than residential counterparts due to the complexity of commercial plumbing codes and system requirements. Healthcare facility plumbing -- including medical gas systems and specialized drain systems -- is a premium specialty.
Service and Repair
Service plumbers who handle repairs, drain cleaning, leak detection, and water heater replacement build strong client relationships and often earn premium rates for after-hours and emergency calls. In Idaho's aging residential stock in cities like Pocatello and Twin Falls, service demand is consistent. Independent service plumbers can build profitable businesses with relatively low overhead.
Industrial and Process Piping
Idaho's food processing industry -- potato plants, dairy operations, and beverage manufacturers -- employs industrial pipefitters who install and maintain process piping systems. Data centers and technology facilities also require specialized plumbing for cooling infrastructure. Industrial pipefitters in Idaho earn $60,000 to $80,000, with the most specialized high-purity piping workers earning more.
How to Become a Licensed Plumber in Idaho
The Idaho Division of Building Safety oversees plumbing licensure. The main license types and requirements:
- Plumbing Apprentice: Register and work under a licensed journeyman or master plumber. Complete an approved apprenticeship program (typically 7,500-8,000 hours over four years).
