Step 1

Before you can put in your new bathroom faucet, you’ll need to remove the old one. To start this process, shut off the water supply valves under the sink and be sure to remove any pressure and water that may still be backed up in the lines. You can do this by simply turning the faucet handles.

Now you can go ahead and disconnect the hot and cold water supply lines using the basin wrench. Use the rag to mop up any water leakage.

Step 3

Disconnect the lift rod and remove the nuts from underneath. Now you can remove the old faucet and drain plug.

Step 1

Check the instructions that came with your new faucet. These will be more specific to the faucet. Generally, you’ll need to install the gasket on the bottom of the faucet using plumber’s putty. After you’ve done this, just mount the faucet through your existing mounting holes. Tighten the mounting nuts.

Step 2

You may need to assemble the new faucet a bit, like attaching the handles, if it didn’t already come preassembled.

Step 3

Install the drain by screwing the nut until it’s sitting at the very base of the drain body, and them place the new gasket over the nut. Depending on your gasket, you may be able to simply screw it on, others require pushing the gasket into place.

Step 4

Using silicone or plumber’s putty, apply a bit to the underside of the new flange. Put the drain body into position, be sure that the pivot hole is facing towards the back of the sink, and then screw the new flange in on top.

Step 5

Tighten the nut and gasket on the drain, and clean up any leftover silicone.

Step 6

To install the drain rod, unscrew the pivot nut, and pace the horizontal rod through the hole, tightening the nut back on. Then slide the strap and clip onto the end of the horizontal rod. Insert the lift rod at the back of the faucet through the top of the strap and tightly secure with a screw.

Step 7

Reconnect the hot and cold water supply, remember hot is on the left and cold is on the right! And connect the supply lines to the water valves. You may need to use a basin wrench in order to reach.
