Toilet Relocation Outward

The relocation of toilets outward requires selecting a plan based on home or outdoor scenarios and strictly adhering to regulations and technical requirements.

Home Scenarios

1. Legal and Regulatory Restrictions

   • Location Compliance: According to the "Residential Design Code", bathrooms cannot be directly placed above the bedrooms or living rooms of lower-level occupants, and it is prohibited to convert non-waterproof areas (such as balconies or ordinary rooms) into bathrooms; otherwise, restoration to the original state and fines may be imposed.
   • Waterproofing Requirements: The new bathroom area must be coated with a double layer of waterproofing paint and pass a 48-hour closed-water test. Poor sealing at the floor penetration points may lead to condensation water dripping to the lower level.

2. Technical Challenges and Solutions

   • Short-Distance Relocation (≤10cm): Use a toilet offset connector to link the original sewage pipe with the new toilet outlet, but this may affect flushing performance and should be installed after floor tile laying.
   • Long-Distance Relocation:
     • Raising the Floor: Lay pipes and raise the floor to bury them, but this increases inconvenience and affects aesthetics.
     • Creating a New Opening: Open a new sewage outlet below the floor slab, requiring consent from the lower-level owner and ensuring connection with the original system.
     • Rear-Discharge Toilet: The sewage pipe is arranged along the wall, suitable for long-distance relocation, and requires professional installation.
   • Innovative Solutions:
     • Partial Expansion: Incorporate an adjacent balcony into the bathroom and use "overhead rather than underground" piping to reduce leakage risks.
     • Functional Separation: Move the sink outside the bathroom to relieve space pressure without altering the sewage system.
     • New Sewage Pump: Use a 32mm thin pipe + grinder for long-distance relocation, costing approximately 3,000-4,000 yuan.

Outdoor Scenarios

Outdoor mobile toilets offer advantages such as flexible deployment, rapid gap-filling, and reduced construction and maintenance costs, making them suitable for initial stages of large residential areas, seasonal scenic spots, temporary markets, etc. Common types include waterless packaged public toilets, foam-sealed types, water-flush types, solar-powered types, mobile trailer types, high-pressure air-water flush types, prefabricated integrated public toilets, and simple eco-friendly public toilets, which can be selected based on needs.
