Yes, a leaking shower can cause mold. Mold is caused by dampness, and a leaky shower provides the right conditions for it to grow and spread.
- The moisture from the water seeps into walls and floors creating an ideal environment for mold to grow in.
- Leaking showers can provide enough moisture over time to allow mold spores to settle in walls and floors or other areas of your bathroom.
- Moisture also encourages fungal growth which often leads to black spots on surfaces under tiles or around corners near showers.
Therefore, it's important that you address any leaks promptly so as not to create an environment where mold can thrive.
