        "text": "Tile itself is water-resistant, but it is not waterproof on its own. Grout lines and standard cement backer boards can absorb moisture and humidity over time. If a continuous waterproofing barrier is missing behind the tile, water can migrate into wall studs and subflooring, causing hidden structural rot and mold development. Professional shower builds incorporate specialized waterproofing systems, such as sealed waterproof membranes and correctly sloped shower pans, to keep moisture within the drainage plane and away from the home's structural framing.",
