Faucet Installation & Replacement Cost in California
A leaky or dated faucet is one of the most common reasons homeowners call a plumber, and one of the more variable jobs in terms of price — the faucet itself can range from budget to designer, and what's happening under the sink matters as much as what's visible on top.
Kitchen faucet cost
Kitchen faucet installation labor typically runs $150-$400, on top of the fixture itself, which ranges from around $80 for a basic single-handle model to $600 or more for a pull-down, commercial-style, or designer faucet. Kitchen jobs tend to run toward the higher end of the labor range because of tight cabinet space, multiple supply lines, and sometimes a garbage disposal or dishwasher connection nearby that the plumber has to work around.
Bathroom faucet cost
Bathroom faucets are generally quicker to access and swap, with labor typically running $120-$300 and fixtures ranging from about $60 for a basic model to $400 for higher-end finishes and widespread designs.
Outdoor and utility faucet cost
Laundry room and utility sink faucets are usually priced similarly to a basic bathroom faucet. Exterior hose bibs are a different job entirely with their own cost range — see our dedicated guide to hose bib repair and replacement cost.
What pushes the price up
- Hole configuration mismatch. Moving from a single-hole to a widespread (3-hole) faucet, or vice versa, may require countertop or sink modification — sometimes not possible without replacing the sink or countertop itself.
- Pull-down sprayers and pot fillers add plumbing connections and sometimes a dedicated shutoff, increasing both material and labor.
- Old, corroded shutoff valves under the sink often need replacing at the same time — trying to reuse a valve that won't fully close is a common source of a "successful" faucet swap that leaks a week later.
- Tile or stone cutouts for a new faucet position require coordination with a tile setter, not just a plumber.
Why the faucet you choose affects more than your water bill
Modern low-flow aerators are a bigger factor in household water use than most homeowners assume. A 2012 study in Journal AWWA by William DeOreo and Peter Mayer, Insights into Declining Single-Family Residential Water Demands, analyzed long-term residential water use trends and found that the shift toward more efficient fixtures — faucets included — has been a major driver of falling per-household water consumption nationwide, even as home sizes have grown. Replacing an old, high-flow faucet with a modern WaterSense-labeled model is a small material cost at installation time that keeps paying off on every use for years afterward.

DIY vs. professional installation
Swapping a faucet is legal to DIY in California and a common weekend project, but the failure points are consistent: over-tightened or under-tightened supply line connections, a shutoff valve that doesn't fully close and floods the cabinet the first time it's needed, or a mounting nut that's hard to reach and gets cross-threaded in a cramped cabinet. If your existing shutoff valves are old, or you're changing anything about the hole configuration, it's worth having a licensed plumber handle it — see our broader guide to what you can legally do yourself in California.
