Replacing a kitchen faucet can seem intimidating, but with the right tools and a little care, it’s a straightforward DIY project that can refresh your sink area and improve daily usability. Whether you’re upgrading to a pull-down sprayer, a touchless model, or a classic chrome finish, the process shares core steps. This guide walks you through planning, installation, and testing so you can complete the job with confidence.
Before you start, take time to plan. Measure your sink’s faucet hole configuration (usually 1, 2, or 3 holes) and choose a faucet that fits your deck plate or requires a single hole. Consider height, reach, and the type of handle you prefer—single-handle faucets are quick to adjust, while dual-handle models give precise control.

Tools, parts, and safety
- New faucet compatible with your sink (check hole count and mounting type)
- Adjustable wrench and/or basin wrench
- Bucket, towels, and a flashlight for visibility
- Plumber’s tape (Teflon) and silicone sealant or plumber’s putty
- Rags to wipe spills and dry connections
- Optional: new supply lines if the old ones are worn
Step-by-step replacement
- Shut off hot and cold water valves under the sink. Open the faucet to relieve pressure and drain as much water as possible.
- Place a bucket and towels to catch any residual water. Disconnect the supply lines from the faucet using a wrench.
- If the old faucet uses a deck plate, remove it and inspect the mounting surface. Remove the mounting nuts under the sink with a basin wrench.
- Lift the old faucet from above the sink and clean the mounting surface thoroughly. Remove any old sealant or debris that could interfere with a good seal.
- Install the new faucet’s gasket or seal as directed. Insert the faucet through the mounting holes and tighten the retaining nuts from underneath, snug but not overtightened.
- Reconnect supply lines with plumber’s tape on threads where needed. Tighten firmly but avoid overtightening which can damage fittings.
- Turn on the water supply and check for leaks at every connection. If leaks persist, tighten slightly or reseat the seals. Run the faucet to purge air from the lines.
- Finish by wiping down the area and making sure the handle operates smoothly. If you encounter a leak you’ll need to re-tighten or reseat the gasket.
Tips for a smoother install
When selecting a faucet, consider the finish to match existing hardware and the durability of braided stainless steel supply lines. If your sink has a large or uneven countertop, ensure the faucet’s height and spout reach accommodate pots and tall glasses. Some faucets include quick-connect fittings that simplify installation, while others rely on traditional compression fittings. Reading the manufacturer’s instructions ahead of time can save you trouble and time.
Smart tips: if you’re replacing an old faucet with a modern pull-down model, ensure the spray hose retracts cleanly and that the sprayer diverter is functioning properly. For more ideas and guides, visit HausFixr.
