5 Signs Your Shower is Leaking

Shower leaks can cause serious water damage if left untreated. Here are 5 warning signs to watch for.

1. Water Stains on Walls or Ceilings

Yellow or brown stains on walls or ceilings below your bathroom indicate water is seeping through. This is a clear sign of a leak.

2. Soft or Spongy Walls

If bathroom walls feel soft or spongy to the touch, water damage has likely compromised the structure. This requires immediate attention.

3. Mold or Mildew Growth

Excessive mold or mildew in your shower indicates moisture isn't drying properly, suggesting a leak or poor ventilation.

4. Crumbling or Cracked Grout

Deteriorating grout allows water to penetrate behind tiles. If your grout is crumbling, it's time to reseal.

5. Musty Odors

A musty smell in your bathroom often indicates hidden moisture and mold growth, suggesting a leak.
