Materials Required

New bathroom sink
Basin wrench
Adjustable wrench
Pliers
Plumber's putty
Caulk gun
Caulk
Safety glasses

Step 1: Turn Off Water Supply

Before starting any plumbing work, it's crucial to turn off the water supply to the sink. Locate the shut-off valves under the sink and turn them clockwise until the water stops flowing.

Step 2: Disconnect Water Lines

Use the basin wrench to loosen the nuts that connect the water supply lines to the sink. Be careful not to overtighten or damage the lines. Once loose, use pliers to pull the lines off the sink.

Step 3: Detach Drain Line

Use the adjustable wrench to loosen the nuts that hold the drain line in place. Gently pull the drain line off the sink.

Step 4: Remove Old Sink

If the sink is attached to a countertop, gently lift it straight up. If it's a drop-in sink, pull it out of the countertop. Be careful not to damage the countertop or the sink.

Step 5: Prepare New Sink

Apply a bead of plumber's putty around the rim of the new sink's drain hole. This will create a watertight seal.

Step 6: Position New Sink

Carefully place the new sink into the countertop or vanity. Align the drain hole with the drain in the countertop.

Step 7: Reattach Drain Line

Slide the drain line onto the sink's drain hole and tighten the nuts with the adjustable wrench. Ensure the connection is secure but not overtightened.

Step 8: Reconnect Water Lines

Screw the water supply lines onto the new sink's faucet. Tighten the nuts using the basin wrench.

Step 9: Caulk Around Sink

Apply a bead of caulk around the seam between the sink and the countertop or vanity. This will prevent water from seeping underneath the sink.

Step 10: Test and Finish

Turn on the water supply and check for any leaks. If everything is working properly, you've successfully changed your bathroom sink. Enjoy your new and refreshed bathroom!
