Renovating Your Bathroom? A Plumbing Checklist

A bathroom remodel touches supply lines, drain lines, and ventilation all at once, and the plumbing decisions you make early shape how smoothly the rest of the project goes.

Before Demo Begins

Have a plumber assess the condition of existing supply and drain lines behind the walls; discovering corroded galvanized pipe mid-project causes far more disruption than planning for it upfront.

During the Remodel

Moving a tub, shower, or toilet even a few feet can require rerouting drain lines and adjusting the vent stack, which is far easier to plan before tile and drywall go in than after.

Fixture Selection

Higher-end faucets and shower systems vary in the rough-in dimensions they require; confirming compatibility with your existing plumbing before purchase avoids a return trip.
