Step 6 · Clean Shower Base and Drain Pipe
Once the old drain is removed, it is crucial to clean all surfaces thoroughly. Use a putty knife or plastic scraper to carefully remove all of the old plumber's putty or silicone from the top surface of the shower base around the drain hole. Also, clean the underside of the shower base. Use a rag with denatured alcohol or mineral spirits to wipe the surfaces clean, ensuring a perfect seating for the new drain. Also, wipe the inside and end of the P-trap pipe.
