Bathroom water supply lines are the pipes that deliver hot and cold water to fixtures like sinks, showers, and toilets. Made from materials such as copper, PEX, or PVC, each type offers distinct advantages in flexibility, durability, and resistance to corrosion. Choosing the right material ensures long-term performance and prevents common issues like scale buildup or leaks.
