        "text": "Complete waterproofing behind the tile is essential because tile and grout alone are not watertight. Water penetrates porous grout lines over time, which can rot wood framing, damage subfloors, and foster hidden mold growth. A proper installation includes a dedicated waterproof barrier, such as a liquid-applied membrane or sheet membrane, applied over moisture-resistant backer board in all shower and tub surrounds. Proper slope toward the drain and sealed pipe penetrations ensure moisture drains away without seeping into surrounding walls.",

        "description": "Yes. Grout and tile are not waterproof, so a dedicated waterproofing membrane behind the tile is required to prevent leaks, rot, and mold inside the walls."
