Homeowners can't reliably detect waterproofing defects in new shower installations before catastrophic water damage occurs

DIY homeowners and contractors installing new showers lack clear diagnostic methods to identify waterproofing failures like membrane bubbles early, leading to hidden water damage, mold, structural rot, and expensive remediation. Current solutions rely on trial-and-error, contradictory advice from forums, or waiting for visible damage to appear—by which point tens of thousands in repairs may be needed.
