  "articleBody": "A new bathroom addition is a major investment where small oversights behind the walls can cause long-term water damage. Watch out for these common installation pitfalls.\n\nCommon Mistakes to Avoid\n- Failing to verify drain pipe slope and venting: Sinks, showers, and toilets need specific slope and proper atmospheric venting to drain correctly without gurgling or sewer smells.\n- Treating waterproofing as just cosmetic tile work: Tile and grout are not waterproof on their own; omitting sealed shower pans and approved backer boards leads to hidden rot.\n- Inadequate exhaust fan ducting: Venting damp air directly into an attic rather than through the exterior roof or wall breeds moisture issues.\n- Placing toilets directly over structural joists: Forgetting to verify subfloor framing before laying out fixtures can require complex structural sistering or offset fittings.\n- Covering rough work before inspections: Tiling or boarding over plumbing pipes and electrical circuits before the inspector approves rough-ins results in forced wall demolition.\n\nWhat to Prepare Before You Start\nMake sure your written contractor estimate specifies complete trade coordination, waterproofing methods, ventilation ducting, and inspection schedules.\n\nCall HH Remodeling LLC at 303-505-0866 to speak with Abraham Becerra about building your new bathroom addition cleanly and correctly.",
