Remove any hair or other debris covering the shower drain's perforations. Even a small amount of blockage in these perforations can significantly slow drainage.
Use a screwdriver to remove all screws holding your drain cover in place. Pick out any hair, scum and debris immediately beneath the drain cover. Wear rubber gloves or use tweezers if you prefer not to touch the blockage directly.
Shine a flashlight down the opened drain and try to spot any deeper clogs. Unravel a wire hanger and stick it into the drain, pulling up any visible clogs. Take care not to push the clog deeper into the pipes.
Coat the rim of the base of a toilet plunger with petroleum jelly. Place the plunger over the drain, creating a tight seal. Fill the shower with water up to the top level of the plunger's base. Firmly and rapidly push the plunger downward. Stop when the water drains freely.
Pour a half cup of baking soda down the drain. Pour two cups of white vinegar on top of it. Let the two substances foam and react for about five minutes, then flush the drain with hot water for a few minutes.
Feed a 25-foot quarter-inch plumbing snake into the drain until you hit a clog. Turn the snake's crank to catch the clog and pull it out of the pipes.
Purchase a commercially available chemical drain cleaner. Follow the instructions directed by the product's manufacturer. Always do this step last, as it's dangerous to root around in a drain after you have flushed it with the caustic chemicals in these products.
Contact a professional, licensed plumber if none of the above steps help you determine the cause of your shower's blockage.
