Housing Toilet Movement

Housing toilet movement usually refers to the relocation of the toilet, which involves changing the original installation position of the toilet. The purpose is to optimize space layout, enhance usability, or adapt to a new renovation style. Common methods and precautions are as follows:

I. Main Methods for Toilet Relocation

1. Short-Distance Adjustment Using a Relocation Device Suitable for small-scale relocations (10-30 cm, not exceeding 40 cm), achieved by connecting the toilet's drainage outlet to the original drain pipe with a relocation device. Its advantages include minimal modification and low cost, but it may result in reduced flushing efficiency due to the longer pipe and an increased risk of blockage. During construction, a slope of 1%-3% should be reserved to ensure smooth drainage of sewage.

2. Raising the Floor and Re-laying Pipes By constructing a base platform 180-200 mm high to embed the drainage pipe, this method is suitable for long-distance relocations (exceeding 40 cm). This approach offers flexible layout options but raises the floor, affecting aesthetics and usability (e.g., requiring steps to enter the bathroom) and potentially reducing ceiling height.

3. Switching to a Wall-Hung Toilet or Cutting a Hole in the Floor Changing from a traditional floor-mounted toilet to a wall-hung one, with pipes running along the wall, eliminates the need to raise the floor and offers better concealment. However, it is necessary to confirm whether the floor structure allows for cutting a hole and obtain consent from the downstairs resident. Additionally, a new waterproof layer must be applied to prevent leakage.

4. Same-Floor Drainage Relocation For sunken bathrooms (with a sunken layer height of approximately 30-40 cm), pipes can be directly laid within the sunken layer, offering fewer relocation restrictions and eliminating the need to damage the floor or affect the downstairs resident. However, this method requires the building to have a same-floor drainage structure.

5. Modifying Downstairs Pipes Suitable for inter-floor drainage (where pipes are located in the downstairs ceiling), this method requires professional modification of the pipes from downstairs. It carries higher risks and requires strict consent from the downstairs resident and property management to avoid legal disputes or neighborhood conflicts.

II. Key Construction Precautions

1. Drainage Slope and Sealing: All relocated pipes must maintain an adequate slope (1%-3%) to prevent sewage backflow; connections should be made using specialized glue or hot melting to ensure sealing.
2. Waterproofing: After relocation, a new waterproof layer must be applied, especially around pipe penetrations and the floor, and a closed-water test (lasting more than 48 hours) must pass before continuing construction.
3. Preliminary Assessment: Before relocation, confirm the bathroom's drainage method (same-floor/inter-floor), relocation distance, and construction conditions to avoid rework due to blind operations.
4. Compliance: When involving floor cutting or downstairs modifications, written consent must be obtained from property management and neighbors, and building safety regulations must be followed.
