New bathroom sink
Pop-up drain and stopper
Faucet
P-trap
Supply lines (hot and cold)

Plumber's putty
Basin wrench
Adjustable wrench
Screwdriver

Step-by-Step Instructions

1. Prepare the Workspace

* Turn off the water supply to the sink. * Disconnect the existing faucet and drain lines. * Remove the old sink.

2. Install the Sink

* Apply a thin layer of plumber's putty around the base of the sink. * Position the sink over the hole in the countertop. * Use the included mounting hardware to secure the sink in place.

3. Install the Drain Assembly

* Insert the pop-up drain into the sink hole. * Connect the P-trap to the drain assembly. * Hand-tighten the nuts that secure the P-trap to the drain and sink.

4. Install the Faucet

* Insert the faucet into the designated holes in the sink. * Place washers and nuts on the underside of the sink to secure the faucet. * Hand-tighten the nuts, then use an adjustable wrench to further tighten them.

5. Connect the Supply Lines

* Wrap Teflon tape around the threads of the supply lines. * Connect the hot water line to the faucet's hot water valve. * Connect the cold water line to the faucet's cold water valve. * Hand-tighten the connections, then use an adjustable wrench to secure them.

6. Turn on the Water and Check for Leaks

* Slowly turn on the water supply. * Check for any leaks around the sink, drain, and faucet connections. * Tighten any loose connections as needed.

Tips for Success

* Use Teflon tape on all threaded connections to prevent leaks. * Tighten connections securely, but avoid overtightening. * Apply a small amount of plumber's putty to the drain basket to ensure a watertight seal. * If you encounter any difficulties, consult a professional plumber.
