Is the sewage smell in the bathroom dangerous?

Sometimes, yes. Sewer gas contains chemicals like hydrogen sulfide and methane, which can be harmful in high concentrations. If you notice the smell regularly and experience headaches or nausea, call a licensed plumber immediately.

Why does my shower drain smell even though it’s not blocked?

A smelly shower drain isn’t always clogged. Other problems can all cause odors—even if water is draining properly. Cleaning and refilling the trap often solves the issue, but persistent smells may require a deeper inspection.

What products can be poured into the shower so that there are no smells?

There are several options: - Enzyme-based cleaners that digest organic buildup - Shower drain fresheners or odor blockers - Bleach diluted with water (use sparingly) - Commercial shower drain deodorizers Just remember, overusing harsh chemicals can damage your pipes, so always follow instructions or consult with a plumbing expert.
