HOW TO CLEAR A CLOGGED BATHTUB DRAIN
You can also use a plunger in an attempt to clear the drain. Most people already have a plunger or two in their home for their toilets, but sometimes it can work in a tub as well. The best way to use a plunger in a bathtub is to use a lot of force in an attempt to create a lot of pressure and dislodge the clog. Plungers only work on certain clogs; many times you will have to use a stronger method.
