The answer to 'shower making gurgling noise' is that a gurgling sound in the shower is typically caused by a blockage or obstruction in the drain line. This can be due to a buildup of hair, soap scum, or other debris, which can restrict the flow of water and cause air to be drawn back into the shower drain, creating the gurgling sound.
Some common symptoms of a shower drain issue include slow draining water, foul odors, and water backing up in the shower. To troubleshoot the problem, you can try plunging the drain or using a drain snake or auger to clear the blockage. If the issue persists, it may be necessary to disassemble the drain pipe and remove any clogs manually. In some cases, the problem may be caused by a deeper issue in the plumbing system, and it's best to call a professional plumber to diagnose and resolve the problem.
