How to Replace a Bathroom Faucet: A Simple DIY Guide

Replacing a bathroom faucet is a manageable DIY project that can refresh the look of your bathroom without breaking the bank. With a few tools and some basic know-how, you can upgrade your faucet in a couple of hours. Here's a step-by-step guide to help you replace a bathroom faucet.

Tools and Materials You'll Need

• New faucet
• Adjustable wrench
• Basin wrench (optional but helpful)
• Plumber's tape
• Silicone sealant or plumber’s putty
• Bucket or towels (to catch water)
• Cleaning supplies (rag and cleaner)

Step-by-Step Instructions

1. Turn Off the Water SupplyBefore you begin, locate the water shut-off valves under the sink and turn them off. If your sink doesn’t have individual shut-off valves, you may need to turn off the main water supply. Turn on the faucet to drain any remaining water from the lines.
2. Disconnect the Supply LinesPlace a bucket or towels under the sink to catch any water that might spill. Use an adjustable wrench to loosen and disconnect the water supply lines from the faucet. If the connections are hard to reach, a basin wrench can be particularly useful.
3. Remove the Old FaucetLook for the mounting nuts securing the faucet to the sink. These are typically located underneath the sink. Use a basin wrench or an adjustable wrench to remove these nuts. Once the nuts are off, lift the old faucet out from the top of the sink.
4. Prepare the Sink SurfaceClean the area around the faucet holes to remove any old sealant, grime, or debris. A clean surface ensures a good seal for your new faucet.
5. Install the New FaucetFollow the manufacturer’s instructions that come with your new faucet. Typically, you’ll need to place the gasket or apply plumber’s putty under the faucet base before positioning it on the sink. Insert the faucet through the holes in the sink.
6. Secure the FaucetFrom underneath the sink, screw on the mounting nuts to secure the faucet in place. Tighten them by hand first, then use the adjustable wrench for a snug fit. Be careful not to overtighten, as this can damage the sink or faucet.
7. Connect the Supply LinesReattach the water supply lines to the new faucet. Wrap the threads with plumber's tape before connecting to ensure a watertight seal. Tighten the connections with your wrench.
8. Check for LeaksTurn the water supply back on and slowly open the faucet to check for leaks. If you see any water dripping, tighten the connections a bit more. Wipe around the connections with a dry rag to see if any water seeps out.
9. Seal Around the Faucet (If Necessary)If the manufacturer recommends it, apply a thin bead of silicone sealant around the base of the faucet where it meets the sink. This helps prevent water from seeping under the faucet.
10. Clean Up

Once everything is securely in place and leak-free, clean up any excess sealant or putty. Give the sink area a final wipe-down, and you're done!

Replacing a bathroom faucet is a straightforward project that can make a big difference in your bathroom’s appearance and functionality. With these steps, you can confidently tackle the task and enjoy the satisfaction of a job well done.
