Step 1: Preparing the Sink and Vanity

1. Place the sink upside down on a flat surface and apply a bead of plumber's putty around the drain hole. 2. Carefully lift the sink and place it on the vanity, aligning the drain hole with the vanity's drain opening. 3. Press down firmly on the sink to ensure the putty creates a seal.
