Water heater installation cost by job.
Installed-labor pricing for Wausau, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Wausau typically costs $700–$1,600 for a standard tank and $1,600–$3,900+ for a tankless unit, plus $275–$900 for a new gas line if needed. With many homes built around 1960, older plumbing and gas lines may require upgrades, and Wisconsin’s cold winters mean cold inlet water that affects heater sizing. A permit is generally required, and only owner-occupants or licensed plumbers can perform the work. Most homes use gas, making a gas water heater a practical choice. The federal 25C tax credit offers 30% back (up to $2,000) for heat pump water heaters, but gas units remain common here.
