How to Replace a Kitchen or Bathroom Faucet
A full faucet swap is more involved than the other guides here — this is the realistic view of what's actually required, not a sales pitch either way.
Before you start: this is general information, not a diagnosis of your specific situation. Shut off water where instructed, take your time, and stop if anything looks different than described here. If you're not comfortable at any point, stop and call us — that's what we're here for.
- 1Turn off both hot and cold shutoff valves under the sink, then open the faucet to release pressure and confirm the water's actually off.
- 2Disconnect the supply lines and the drain/sprayer hose (if any) from the old faucet, working in a cramped space with a headlamp and a basin wrench helps a lot here.
- 3Unscrew the mounting nuts holding the old faucet to the sink or countertop from underneath, then lift the old faucet out.
- 4Clean the mounting surface, then follow the new faucet's instructions to set gaskets/plates and feed the new supply lines/hoses down through the mounting holes.
- 5Tighten the mounting hardware from underneath, reconnect supply lines (don't overtighten compression fittings), turn the water back on, and check every connection for drips before you walk away.
This is genuinely the hardest one on this list — tight cabinet spaces, corroded old shutoff valves, and mismatched connections trip people up constantly. If your shutoff valves won't turn, look corroded, or start leaking once you touch them, stop — that's exactly the kind of thing that turns a $0 DIY job into a flooded cabinet. Installed faucets run us about $250 including labor, and it includes swapping any bad shutoff valves we find along the way.
