Water heater installation cost by job.
Installed-labor pricing for Monrovia, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Monrovia, California, water heater installation costs typically range from $800 to $1,800 for a standard tank unit and $1,800 to $4,600+ for a tankless system.

Labor rates reflect the area's median income of $93,827, and installation must comply with the California Plumbing Code (UPC).
