        "text": "Waterproofing must happen behind the tile because tile and grout joints are not completely waterproof on their own. Water vapor and moisture seep through grout lines over time, which can rot standard drywall and framing studs if the substrate is untreated. Professional shower installation requires moisture-resistant backer board, taped seams, and a continuous liquid or sheet waterproofing membrane across all wet areas. Neglecting this crucial step often leads to hidden mold growth, cracked tiles, and structural floor damage that eventually requires a complete tear-out to fix.",
