Step 1: Preparation

Turn off the water supply. Locate the valves under the sink or behind the bathtub and turn them to the "off" position.
Place a bucket or towel beneath the faucet to catch any water that spills during the process.
Remove the aerator from the old faucet. Use a pair of pliers to loosen the aerator and unscrew it.
Disconnect the water supply lines. Use the adjustable wrench to loosen the nuts on the water supply lines. Be careful not to damage the lines.

Step 2: Remove the Old Faucet

Remove the mounting nuts. Use the basin wrench to loosen the mounting nuts located underneath the sink or behind the bathtub. Be careful not to drop the nuts into the drain.
Detach the old faucet. Once the mounting nuts are removed, you should be able to detach the old faucet from the sink or bathtub.
Clean the area. Use a damp cloth to clean the area where the old faucet was installed. Make sure to remove any old sealant or debris.

Step 3: Install the New Faucet

Apply plumber's putty. Apply a ring of plumber's putty around the base of the new faucet. This will help to create a watertight seal.
Insert the new faucet. Carefully insert the new faucet into the hole in the sink or bathtub. Make sure that the faucet is properly aligned.
Secure the mounting nuts. Use the basin wrench to tighten the mounting nuts underneath the sink or behind the bathtub. Be careful not to overtighten the nuts.
Reconnect the water supply lines. Use the adjustable wrench to reconnect the water supply lines to the new faucet. Be careful not to cross-thread the lines.

Step 4: Testing and Final Touches

Turn on the water supply. Slowly turn on the water supply valves under the sink or behind the bathtub. Check for any leaks around the faucet.
Test the faucet. Open and close the faucet several times to make sure that it is working properly.
Install the aerator. Screw the aerator back onto the faucet.
