Faucet Installation Cost: Kitchen, Bath, and the Shutoff Problem

Faucet installation is priced by fixture type and, more than anything, by the condition of the shutoffs and supply lines under the sink. A modern setup with quarter-turn stops is a 30-minute job; corroded multi-turn valves or no stops at all change the scope.

What does faucet installation cost?

A straightforward kitchen or bathroom faucet swap runs $120 to $300 in labor. Widespread bathroom faucets and pull-down kitchen units with sprayers and soap dispensers run $200 to $450. Add $60 to $150 per shutoff valve replacement and $40 to $100 for new supply lines.

What makes it more than a quick swap?

• Old or seized shutoff valves that will not close or leak when reopened
• No shutoffs — the water has to be killed at the main and stops added
• Corroded mounting nuts on the old faucet in a cramped cabinet
• A drop-in sink that must come out to access the faucet
• Basket strainer, disposal, or drain work bundled in

How should the estimate handle the shutoffs?

Assume the customer wants working stops afterward. Quote the faucet swap flat, and state that if the existing stops are not quarter-turn or do not hold, replacing them is recommended at a stated unit price. Reusing a questionable stop is how a faucet job becomes a water-damage callback.

Flat rate or hourly?

Flat rate for the swap so the customer knows the number. Hourly or unit pricing for the variables (stops, supplies, strainer) so you are covered when you open the cabinet. Photograph the under-sink condition on arrival.
