The Entire Process of Mobile Toilet Translation
Quản trị 19 tháng 10, 2026
The translation of a mobile toilet (toilet bowl) requires selecting an appropriate method based on the translation distance, building structure, and requirements. Common solutions and steps are as follows:

I. Using a Toilet Offset Connector (Short-distance translation, within 100-350mm)
- Purchase a finished toilet offset connector: Choose an offset connector with an oval flat pipe for the horizontal pipe and a height of approximately 60mm to ensure compatibility with the original sewage pipe interface.
- Chisel out the floor slab: Before waterproofing, chisel out 20-40mm of the floor slab to provide space for embedding the offset connector.
- Embed the offset connector: Connect one end to the original toilet sewage pipe and extend the other end to the target position. If the translation distance exceeds 300mm, set a slope of more than 3% at the embedding point to prevent blockages caused by poor drainage.
- Pour the floor and waterproofing: Pour the floor and apply waterproofing to a height of approximately 20mm, ensuring the waterproof layer covers the connection point of the offset connector.
- Lay tiles: Lay tiles normally to a height of approximately 30mm to restore floor flatness.
- Install the toilet: Complete the final installation and test the drainage effect.
II. Same-floor Drainage - Floor Slab Lowering (Suitable for bathrooms with lowered floor slabs)
- Confirm the lowered floor slab structure: If the bathroom floor slab is already recessed by 250-350mm, the toilet and drain opening positions can be directly arranged without additional raising or chiseling of the floor.
- Plan the pipes: Use a sloped tee to connect the sewage pipe, avoiding the problem of easy blockage with a straight tee, to ensure smooth drainage.
- Backfill material: Use lightweight bricks or blocks for backfilling to reduce the load on the floor slab and facilitate subsequent maintenance.
Advantages: Free translation without position restrictions; Disadvantages: Only suitable for buildings with lowered floor slabs.
III. Same-floor Drainage - Floor Slab Raising (Suitable for individuals without mobility issues)
- Arrange the horizontal sewage pipe: Use a pipe with a diameter of approximately 110mm to ensure drainage capacity.
- Build the base platform: Use lightweight blocks to build a base platform with a height of 180-200mm and embed the sewage pipe to provide a foundation for toilet installation.
- Floor construction: Normally perform floor leveling, waterproofing, and tile laying to restore floor functionality.
Advantages: Long translation distance and flexible layout; Disadvantages: Raising the floor affects use by the elderly and involves a large amount of work.
IV. Hidden Cistern (Wall-mounted, suitable for long-distance translation)
- Purchase accessories: Choose hidden cisterns and accessories from professional brands (such as Geberit) to ensure reliable quality.
- Install the vertical pipe tee: Connect the horizontal sewage pipe to the target position to optimize the drainage path.
- Install the cistern: Fix the cistern and connect it to the sewage pipe to ensure tightness.
- Build a low wall: Enclose the cistern and pipes with a wall thickness of 180-220mm and a height of 900-1200mm, balancing aesthetics and practicality.
- Install the toilet: Choose between a wall-mounted or floor-mounted toilet based on space requirements.
Advantages: Large translation distance, aesthetically pleasing, and easy to clean; Disadvantages: Cannot be translated to the diagonal wall of the sewage vertical pipe or positions with other vertical pipes on the outside.
V. Inter-floor Drainage - Modifying Drainage at the Neighbor's House (Requires neighborhood consultation)
- Negotiate the modification: Communicate with the downstairs neighbor to modify the sewage pipe at the top of their bathroom, signing a written agreement to clarify responsibilities.
- Waterproofing and trap: Ensure proper waterproofing and install a trap to prevent odors during the modification, avoiding leakage or odor problems.
Advantages: Unlimited translation distance; Disadvantages: Dependent on neighborhood relations, complex construction, and may involve property management approval.
Summary: For short distances, prioritize using a toilet offset connector; for buildings with lowered floor slabs, choose same-floor drainage with floor slab lowering; for long distances or aesthetic requirements, choose a hidden cistern; for special cases, negotiate inter-floor drainage modifications. Before construction, confirm the building structure and property management requirements to ensure compliance and safety.
