Step-by-Step Guide to Replacing a Bathroom Sink

Follow these steps to ensure a successful bathroom sink replacement. Make sure to prioritize safety and proper technique throughout the process.
Preparation and Safety Precautions
- Turn Off the Water Supply: Before starting, turn off the water supply to the sink using the shut-off valves located below or behind the sink. Test both faucet handles to ensure total shutoff.
- Use Protective Gear: Wear protective eyewear, gloves, and other safety gear to prevent injuries while handling plumbing tools.
Removing the Old Sink
- Disconnect the Water Supply Lines: Use an adjustable wrench to loosen the nuts securing the hot and cold water supply lines to the shut-off valves. Remove the lines carefully, and be prepared for any residual water to drip.
- Disconnect the Drain Connection: Loosen the large slip nut holding the P-trap to the tailpipe of the sink’s drain. If necessary, remove the entire trap assembly for easier access.
- Remove the Sink: Depending on the installation, your sink may be secured with clips or caulk. Remove any securing clips and carefully cut through any caulk around the rim. Lift the old sink out of the countertop.
- Prepare the New Sink: If your new sink requires any assembly, do it according to the manufacturer's instructions. Apply plumber's putty or silicone caulk around the edge of the new sink to ensure a watertight seal.
- Position the Sink: Carefully place the new sink into the countertop opening, ensuring it fits snugly. For under-mount sinks, secure it from below with mounting brackets if applicable.
- Reconnect the Drain and Supply Lines: Reattach the P-trap to the sink's drain, tightening the slip nut securely. Connect the water supply lines to the sink’s faucet, ensuring each nut is tight, but not overly so to avoid damaging the fittings.
- Turn On the Water Supply: Once everything is connected, turn on the water supply at the shut-off valves. Check for leaks around the connections, tightening any loose fittings as necessary.
- Test the New Sink: Turn on both faucets to ensure they operate correctly and the new sink drains efficiently. This ensures everything functions properly and your installation efforts are successful.
Final Touches

After installing your new bathroom sink, focus on a few crucial final steps to ensure everything works smoothly and looks great.
Connecting Plumbing
Connect the plumbing by attaching the water supply lines to the faucet. Hand-tighten the connections and then use an adjustable wrench for a secure fit, being careful not to overtighten. Next, install the drain assembly by following the manufacturer's instructions. Ensure the rubber gasket is properly placed to prevent leaks. Once everything is connected, check that all fittings are aligned correctly and securely fastened.
Testing for Leaks
After connecting the plumbing, turn on the water supply to test for leaks. Check all connections—both under the sink and the faucet. If you notice any leaking, turn off the water supply and tighten the fittings as necessary. Allow time for the sink's sealant to cure, typically a few hours, before using the sink to ensure a watertight seal. Confirm that there's no moisture around the sink, drain, or plumbing workmanship.
