How much does kitchen faucet replacement cost?

Having a faucet replaced runs about $150 to $450 including the faucet, or $80 to $200 in labor if you supply it. DIY is mostly the cost of the faucet, $80 to $400, since most homeowners can swap one in under an hour with a basin wrench.

Can I replace a faucet myself?

Yes, faucet replacement is one of the easiest plumbing DIYs. The trickiest part is the cramped space under the sink, where a basin wrench reaches the mounting nuts. Shut off the supply, disconnect, set the new faucet, and reconnect, and you are done.

Do I need a basin wrench to replace a faucet?

It is the one tool that makes the job much easier. A basin wrench reaches the mounting nuts way up behind the sink basin that ordinary wrenches cannot. You can sometimes manage without one, but it is cheap and turns a frustrating job into a quick one.

Should I replace the shutoff valves too?

If the existing shutoff valves are old, corroded, or do not fully close, replacing them while you are under there is smart and cheap. Reliable shutoffs make every future repair easier, and a valve that will not close turns a faucet swap into a bigger ordeal.

Why is my new faucet leaking?

Leaks are usually at the supply connections, either not tight enough or overtightened and cross-threaded, or from a loose mounting. Check the connections first. Also flush the lines with the aerator removed, since debris from the work can lodge in the new faucet.

How we got these numbers

National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for Maryland using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. Maryland's RPP is 1.1 (national baseline = 100) and its BLS labor adjustment factor is 1.10. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.

adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)

RPP(Maryland) = 1.1 · BLS adj = 1.10
