A general contractor can coordinate every aspect of a bathroom renovation, but the actual plumbing work — water lines, drains, vents, fixtures, gas — should be done by a licensed plumber. Most quality general contractors will subcontract that work to a plumbing company like Mainstream, both because it’s required by code and because plumbing mistakes in a remodel are some of the most expensive to fix.

Plumbing work in a bath remodel

  • Rough-in for new tub, shower, toilet, and vanity
  • Drain, waste, and vent (DWV) modifications
  • Supply line reroutes
  • Shutoff valves and water hammer arrestors
  • Final fixture installation and pressure test
