Show me how to install a new sink in my bathroom.

First, you need to turn off the main water supply to the house. Then, you will need to remove the old sink from the counter. Next, you'll want to attach the new sink and secure it to the counter. Make sure all of your connections and assembly is secure before adding the supply lines to the faucet and drain. Once those are connected, turn the water supply back on and test for any issues. Finally, connect the shut-off valve and check ensure the water flow is as intended.
