How to Install a Widespread Faucet
Time Required: Over 1 day

They are available in a wide range of styles and finishes, and you may also want to consider choosing a WaterSense-certified faucet to reduce water usage and save on your water bill.
This guide includes detailed step-by-step instructions that give you all the information youll need to complete your faucet installation project.
