Step 1 · Prepare the Work Area and Remove Stopper

First, prepare your workspace. Place a thick, dry rag or an old towel over the tub floor around the drain to prevent any accidental scratches or damage to the tub's acrylic surface. Next, remove the existing lift-and-turn stopper. To do this, open the stopper, then locate the small set screw on its base. Use an Allen wrench or a small flathead screwdriver to loosen this screw. You do not need to remove it completely. Once loose, unscrew the knob cap from the top of the stopper post, and lift the entire stopper mechanism out of the drain. Clean out any hair or gunk to get a clear view of the drain flange and its crossbars.
