The answer to 'shower making gurgling noise' is that a gurgling sound in your shower is usually caused by a blockage or obstruction in the drain line. This can be due to a buildup of hair, soap scum, or other debris that is preventing the water from draining properly. The gurgling sound is caused by air being forced back up through the drain as the water tries to flow down.
Some common signs of a gurgling shower drain include the water draining slowly, a foul odor coming from the drain, or water pooling around the shower base. To fix this issue, you may be able to clear the blockage yourself by using a plunger or drain snake. However, if the problem persists or you are unable to clear the clog, it's best to call a professional plumber to inspect and repair the drain line.
