The answer to 'shower foul smell' is that the most common causes are buildup of soap scum, mold, or bacteria in the drain or shower head. Symptoms include a persistent, unpleasant odor coming from the shower. To fix this, you can try DIY solutions like using a drain cleaner or vinegar and baking soda to flush the drain, or cleaning the shower head. However, if the smell persists or you suspect a more serious issue like a clogged pipe or sewer gas leak, it's best to call a professional plumber to diagnose and resolve the problem.
Ignoring a foul shower smell can lead to more serious issues like mold growth, so it's important to address it promptly. A professional plumber has the expertise and tools to properly identify and fix the root cause, ensuring the problem is resolved safely and completely.
