How to Move the Toilet During Bathroom Renovation

Moving the toilet during bathroom renovation can be achieved through several methods, and the appropriate solution should be selected based on the actual situation:

1. Using a Toilet Offset Connector This is the most common method for short-distance relocation, suitable for scenarios where the relocation distance is between 10-40 centimeters. An integrated offset connector is suitable for relocations within 20 centimeters, achieved by installing a 100-diameter flat pipe in the middle, with adjustable pipe length; for side-pipe offset connectors, the relocation distance is recommended not to exceed 50 centimeters. Key construction points: For every 10 centimeters of relocation, at least a 0.5-centimeter slope (i.e., a 1%-3% slope) should be reserved to ensure smooth drainage; if the relocation exceeds 10 centimeters, a straight-flush toilet should be replaced to reduce the risk of blockage. This method involves minimal alterations and low cost, but it may affect the flushing effect and pose a risk of blockage with long-term use.

2. Renovation of Inter-floor Drainage Bathrooms If the bathroom has inter-floor drainage (i.e., the drainage pipe is inside the ceiling of the downstairs unit), theoretically, the toilet pipework can be rearranged by drilling holes in the floor slab after negotiating with the downstairs neighbor. However, in practice, this solution is highly impractical because it involves the privacy and safety of the downstairs occupants, and 99% of neighbors will refuse to cooperate. It should only be considered in special circumstances (such as self-built houses or unified renovations).

3. Renovation of Same-floor Drainage Bathrooms with a Sunken Slab If the bathroom has same-floor drainage and includes a sunken slab (i.e., a drainage space formed by structural slab lowering), moving the toilet does not require damaging the floor slab. The drainage pipe position can be directly adjusted within the sunken slab, allowing the toilet to be installed in any area, provided that the new position connects smoothly with the main drainage stack and sufficient slope is reserved. This solution offers flexible alterations and no risk of leakage, but it is necessary to confirm whether the depth of the sunken slab meets the construction requirements.

4. Wall-mounted Toilet Renovation A wall-mounted toilet achieves position adjustment through a concealed cistern and wall-mounted drainage, suitable for scenarios involving short-distance renovation of the sewage pipe. Construction points: The cistern frame needs to be embedded in the wall, and a hole should be drilled in the main drainage stack to connect the toilet drainage pipe, while reserving an inclined slope hole to ensure smooth drainage. This method offers strong aesthetics and saves space, but it is costly and has certain requirements for the wall structure (requiring a load-bearing wall or a newly built false wall).

Selection Recommendations:

• For short-distance relocations (≤40 centimeters), prioritize using an offset connector, strictly controlling the slope and toilet type;
• For same-floor drainage bathrooms with a sunken slab, direct position adjustment is possible, offering the highest flexibility;
• Wall-mounted toilets are suitable for scenarios with high space and aesthetic requirements;
• The inter-floor drainage solution should be carefully evaluated for feasibility to avoid neighbor disputes.
