Replace Your Bathroom Faucet: Easy Guide · Step 2 of 5
This guide demonstrates how to replace a bathroom faucet. Begin by turning off the water supply using the shut-off valves under the sink and relieving any remaining water pressure. Disconnect the old faucet's supply lines with an adjustable wrench, catching any dripping water. Remove the faucet's mounting nuts, likely requiring a basin wrench, to detach the faucet from the sink. Install the new faucet, following the manufacturer's instructions, which typically involve positioning the faucet base, connecting supply lines, and securing it with mounting hardware. Finally, turn the water supply back on and check all connections for leaks, running both hot and cold water to verify proper function.

FAQs
The project states 'beginner' and '2 hours'. Is this realistic for someone with no plumbing experience?
Yes, replacing a bathroom faucet is generally beginner-friendly if you follow instructions carefully. The 2-hour estimate is for a smooth installation; seized nuts or tight spaces can extend this, so allocate a bit of extra time. Take your time and don't rush the steps.
Is a basin wrench truly necessary for this project, or can I just use my adjustable wrench?
A basin wrench is highly recommended, as it's designed to reach and grip the often-tight mounting nuts in the confined space under a sink. While an adjustable wrench might work for accessible nuts, the basin wrench significantly simplifies this often frustrating step, especially for older faucets.
What's the most common mistake beginners make that leads to leaks after installing a new faucet?
Not properly tightening the supply line connections is a common cause of leaks. Ensure they are hand-tight, then use a wrench for an additional quarter to half turn, being careful not to overtighten and strip the threads. Always use new supply lines, often included with your new faucet.
What should I do if the old faucet's mounting nuts are corroded or stuck and won't loosen?
First, apply a penetrating oil (like WD-40) to the nuts and let it sit for 15-30 minutes. If they still won't budge, you might need to carefully use a hacksaw or oscillating tool with a metal blade to cut through the nuts or bolts, but exercise extreme caution to avoid damaging the sink or surrounding plumbing.
