Shower Drain Mold: Frequently Asked Questions
Hopefully, this guide helped you tackle your shower drain mold problem! Here are a few common questions that arise after reading the removal tips:
What makes shower drains such a good place for mold to grow?
Shower drains offer the perfect conditions for mold growth: moisture, darkness, and a constant supply of organic matter like hair and soap scum. This combination creates a breeding ground where shower drain mold can thrive.
