Most bath tub is clogged by hair. A plumber’s snake is a great tool to remove hair in the drain. However, some tub constructions do not allow the snake to get inside the drain hole. In situation like this, if there is a tub access cover, you can put the snake through the access cover to remove the clog as shown below.
