4 Signs of a Hidden Bathroom Leak

A leak in the shower or bathroom can have damaging consequences for your home. An untreated leak, for instance, can destroy the foundation of your home. Thankfully, a leak manifests itself in several noticeable ways, both obvious and subtle. Look for the following signs of a shower leak.

Stains and Mold

The formation of stains and mold near the shower or a bathtub is not unusual, since these areas are constantly wet. If you constantly clean these stains, however, and you still see them, it might signal worse problems for your bathroom plumbing. Similarly, look out for any stains or mold that form in bathroom areas that are constantly dry, such as the walls, ceilings, and floors. You may even see some stains or mold in the ceilings of rooms next to or beneath the bathroom. 

Damages and Cracks

Water is powerful enough to compromise the structure of your home. Cracks in any part of the bathroom or nearby rooms are a direct indication of a hidden leak. Damage from a water leak appears in ceilings, walls, or floors, often in the form of cracks, staining, or softening. Drywall, paint, and wallpaper are the most vulnerable to leaks and will have the most noticeable damage. Just like with stains, cracks in ceilings and rooms next to or below the bathroom can represent the problem. In the case of floors and ceilings, leak damage also appears as loose tiles.

Distinctive Smells

A musty, earthy smell in the bathroom, like something you’d find in an old basement, is a sign that there’s something wrong with your shower plumbing. This smell indicates that the leaking water isn’t evaporating appropriately and can affect the rest of your bathroom. Additionally, the distinctive smell may also indicate the presence of mold, another sign of hidden leakage.

Expensive Water Bills

One more sign of a leak present in your bathroom is through changes in your monthly water bill. If you monitor your water use and your water bill is disproportionally greater than your estimated use, it likely means there’s a leak somewhere, wasting an excess of water. Repairing the leak should stabilize your water bills.
