Key cost factors
PEX vs copper
PEX is flexible, fast to install, freeze-resistant, and the most affordable choice. Copper costs more but is long-proven and preferred by some owners.
Access and patching
Repiping means opening walls to reach the pipes. The number of access points and the drywall repair and repainting afterward add to the total.
