Why does my septic smell when I shower?

A septic smell in your shower when you shower usually means sewer gas is escaping, often from a dry P-trap (needs water), a clogged drain with bacterial buildup (hair/scum), or a blocked plumbing vent allowing gases to back up, sometimes indicating bigger septic/sewer line issues. The hot water from the shower exacerbates the odor from trapped gunk or gases.
