Step 7 · Apply Sealant to New Drain Flange

Take the new drain flange (the top piece with the strainer threads). If using plumber's putty, warm it in your hands and roll it into a snake about 3/8-inch thick. Apply this rope of putty to the underside of the drain flange. If your shower base is acrylic or the drain instructions recommend it, apply a continuous bead of 100% silicone caulk instead of putty.
