Moving the Toilet Position During Renovation

Admin October 08, 2026

It is feasible to move the toilet position during renovation, but it is necessary to choose an appropriate method according to the specific situation and pay attention to relevant matters.

Short-distance Relocation (10 - 20 cm)

Short-distance relocation is relatively safe and can be achieved using a toilet offset connector. This method involves minimal modification, low cost, and relatively simple construction. However, using a toilet offset connector may affect the flushing effect and increase the risk of blockage. During construction, a slope of 1% - 3% should be reserved to ensure smooth drainage of sewage and reduce the possibility of blockage.

Long-distance Relocation (Over 20 cm)

If the relocation distance exceeds 20 cm, it is usually necessary to raise the floor by about 12 cm. The purpose of raising the floor is to increase the slope of the pipeline and ensure smooth drainage. Only by ensuring sufficient slope can sewage flow smoothly into the drainage pipeline under the action of gravity, avoiding problems such as water accumulation and blockage.

Relocation Based on Different Drainage Methods

  • Same-floor Drainage (Sunken Toilet): Since the drainage pipeline is in one's own home, modification is relatively convenient. One can choose to directly lengthen or shorten the pipeline for relocation. This method has no impact on the downstairs residents and is relatively flexible in operation.
  • Inter-floor Drainage (Drainage pipe passes through the floor slab for drainage): If relocation is desired, one can try to negotiate with the downstairs neighbors to drill holes in the floor slab and rearrange the toilet pipeline. However, in actual operation, the probability of the neighbors agreeing is relatively low, as this may have a certain impact on the decoration and living of the downstairs residents.

Other Relocation Methods

  • Floor Drain to Wall Drain Conversion: Connect the toilet directly to the sewage riser. After relocation, the toilet is less likely to get blocked, and this method is applicable to both same-floor and inter-floor drainage. However, this method requires the construction of a false wall, which can be combined with a niche to create storage space and increase the practicality of the bathroom.
  • Wall-mounted Toilet: Its pipeline does not run on the floor, and the toilet drainage is directly connected to the riser of the main pipe. It is only suitable for modifications very close to the sewage pipe. Wall-mounted toilets have a simple appearance and save space, but they have relatively high installation requirements.

Regardless of the method used, it is necessary to ensure a slope in line with the national standard of 0.02 and carry out proper waterproofing to prevent sewage leakage and cause losses to the downstairs residents. At the same time, it is recommended to have the construction carried out by professionals to reduce the risk of blockage after relocation.
