Identify Drain Stopper Type

What happens here

Inspect the center of the bathtub drain stopper for a visible screw, commonly a Phillips head type. Insert a Phillips head screwdriver into the screw and attempt to turn it counter-clockwise to see if the stopper can be easily removed. If the screw is rusted or stripped, or if the stopper has an internal cross-shaped mechanism without a direct screw, proceed to use a specialized plumbing tool.

Goal: Begin by identifying the type of fastener securing the drain stopper, which is typically a Phillips head screw in the center. Attempt to loosen this screw with a suitable screwdriver.
