Toilet Relocation During Renovation

Relocating a toilet during renovation is feasible, but appropriate methods must be selected based on the relocation distance, drainage method, etc., and construction specifications must be followed. Here are specific methods and considerations:

1. Use a Toilet Offset Connector
Suitable for short-distance relocation (usually 10-30 cm, not exceeding 40 cm).

• Integrated Offset Connector: Suitable for relocations within 20 cm, easy to install, but with limited relocation distance.
• Side-pipe Offset Connector: The relocation distance should preferably not exceed 50 cm, and a slope must be reserved: for every 10 cm of relocation, at least a 0.5 cm slope should be reserved in the pipeline to ensure smooth drainage. If the relocation exceeds 10 cm, it should be used with a straight-flush toilet to prevent blockages caused by poor drainage in siphon toilets.

2. Raise the Floor and Re-lay the Pipeline
Suitable for relocation distances exceeding 20 cm.

• Build a base platform 180-200 mm high to embed the sewage pipe and raise the floor by 12 cm to increase the pipeline slope and meet drainage requirements.
• This method requires sacrificing some floor height but can solve long-distance relocation problems and offers relatively flexible construction.

3. Negotiate with the Downstairs Neighbor to Re-arrange the Pipeline
Only applicable to bathrooms with inter-floor drainage (i.e., the sewage pipe passes through the floor slab to the downstairs).

• Negotiate with the downstairs neighbor to drill holes in the floor slab and re-arrange the toilet pipeline, directly connecting it to the downstairs main drainage pipe.
• Difficulty: Neighbor's consent is required, and property management approval may be involved, making actual operation relatively difficult.

4. Use a Wall-mounted Toilet
Suitable for bathrooms with same-floor drainage and a sunken floor.

• Connect the toilet drainage directly to the main vertical pipe, with the water tank hidden in the wall, saving space and looking aesthetically pleasing.
• Limitation: Only suitable for short-distance renovations of the drainage pipe (e.g., relocation within the sunken floor). It cannot be used if the original pipe position is too far away.

Key Considerations

• Slope Standard: The slope of the relocated pipeline must comply with the national standard (0.02), i.e., a 2 cm drop per meter of pipeline to avoid water accumulation or odors.
• Waterproofing: Relocation construction may damage the original waterproof layer. It is necessary to reapply waterproof coating and conduct a 48-hour closed-water test to ensure no leakage.
• Professional Construction: Pipeline connection, slope adjustment, etc., should be carried out by professionals to avoid blockages or leaks caused by improper construction.

Summary: The method of toilet relocation should be selected based on the actual situation. For short distances, an offset connector is preferred; for long distances, the floor can be raised or a wall-mounted toilet can be used. For inter-floor drainage, negotiation with the downstairs neighbor is required. Regardless of the method, strictly following the slope standard, ensuring proper waterproofing, and having the work done by a professional team are crucial.
