Mobile Toilet Sewer Distribution Map

Currently, there is no specific diagram directly related to the 'Mobile Toilet Sewer Distribution Map', but information on the drainage methods and layouts for toilet sewer renovation and relocation in bathrooms can be provided for reference.

Same-Floor Drainage

Same-floor drainage refers to the arrangement where all branch pipes are laid within the same floor without penetrating the floor slab. This drainage method is typically used in sunken bathrooms and is the most convenient for later modifications. The drainage pipes can be laid at the bottom of the sunken area, and maintenance only requires prying up one tile from the homeowner's floor. Since the pipes do not penetrate the floor slab, interference between floors is reduced, and the risk of water leakage is also minimized.

Inter-Floor Drainage

In inter-floor drainage, the branch pipes need to penetrate the floor slab, with the ends of the pipes for the toilet, floor drain, and sink extending to the ceiling of the floor below. This drainage method is more difficult to modify because any changes require coordination with the neighbors downstairs, and construction may impact them. Inter-floor drainage is more common in older buildings, and special attention should be paid to waterproofing and pipe sealing during renovation.

Toilet Relocation Methods

• Integrated Relocator: Suitable for short-distance relocations of ≤200mm. It has a fixed shape, does not require raising the floor during installation, and is less prone to pipe blockage. It is suitable for minor adjustments to the toilet position.
• Oval Flat Pipe Relocator: Suitable for long-distance relocations of 200–500mm. It achieves displacement through connectors and a stretchable oval flat pipe, requiring a slope of 5mm per 100mm and increasing the垫层 (sub-base) by at least 50–60mm. It is suitable for situations requiring significant adjustments to the toilet position.
• Raising the Floor Slab: The bathroom floor is raised by 180–200mm at once, with a 110 sewage pipe embedded inside. It is suitable for ultra-long-distance relocations of ≥1m but significantly increases the floor height, affecting space usage.
• Lowering the Floor Slab: Utilizing a naturally sunken bathroom (where the floor slab is already recessed by 250–350mm), the drainage pipes can be arranged freely. During construction, two layers of waterproofing should be done first, followed by backfilling with expanded clay or foamed cement. It is suitable for renovations of sunken bathrooms.
• Relocating the Toilet Downstairs: When the home has inter-floor drainage and the neighbors downstairs are willing to cooperate, the riser can be directly relocated to above the bathroom downstairs. This method requires coordination with the neighbors downstairs but has a lower construction difficulty.
• Wall-Hung Toilet Position: The drainage pipe for a wall-hung toilet is arranged along the wall, meeting the needs of long-distance relocation without worrying about later blockages. It is suitable for bathrooms with high space layout requirements.
