        "text": "No, tile and grout are porous and do not provide an impermeable moisture barrier. Water, steam, and cleaning chemicals regularly pass through hairline grout cracks and the porous structure of standard ceramic or stone tiles. Without a dedicated waterproofing layer directly behind the tile—such as a sheet membrane, liquid barrier, or waterproof foam backer board—moisture penetrates the wall cavity and subflooring. Over time, trapped moisture rots wooden studs, deteriorates drywall, rusts plumbing fasteners, and promotes hidden mold colonies behind the shower walls.",

        "description": "No. Tile and grout are naturally porous and let water through; a dedicated waterproof membrane behind the tile is essential to prevent framing damage."
