Locate and turn off the shut-off valves beneath the sink, shutting down both hot and cold water supplies.

Employ a pipe wrench or adjustable pliers to disconnect existing plumbing, loosening nuts and washers connecting the old drain pipes.

Prepare the sink opening by removing any remaining plumber's putty or debris, using a putty knife or scraper.

Craft a small rope of plumber's putty and apply it around the underside of the new sink strainer. Press the strainer into the sink opening for a secure seal.

Step 7: Embrace the Basket Strainer:

Thread the slip nut onto the basket strainer from beneath the sink and use pliers to tighten it securely, anchoring the strainer in place.

Step 8: Connect the Tailpiece:

Join the tailpiece to the bottom of the basket strainer with a slip nut, ensuring a snug and secure connection using pliers.

Step 9: Assemble the P-Trap:

Link the P-trap to the tailpiece and the wall drain pipe, maintaining a slight downward angle for effective drainage.

Step 10: Check for Leaks:
