Moving the Toilet Half a Meter

The toilet can be moved half a meter, but the project is complex and involves risks, requiring careful planning and selection of an appropriate solution.

I. Common Relocation Solutions and Key Points

1. Drainpipe Relocation
   This involves breaking the original floor and wall tiles, laying new drainage pipes, and performing waterproofing. This solution requires significant work, and it is essential to ensure the new pipes have a reasonable slope (usually 1%-2.6%) to avoid poor drainage or odors. After construction, thoroughly test the drainage and restore the floor and wall decorations.

2. Toilet Elevation Method
   This involves connecting a bent drainpipe to the original drain outlet, requiring precise calculation of the pipe's bending angle and length. This method may take up extra space, and the elevated toilet may affect comfort (e.g., legs hanging in the air while using the toilet). During construction, strictly control the drainage slope to prevent water accumulation or blockages.

3. Relocation Devices or Pipe Modifications

   • Cross-floor Drainage: If the relocation distance is within half a meter, a Geberit relocation device can be used; for distances exceeding half a meter, a 90mm round pipe should be used to relay the drainage pipes, with a slope controlled between 1%-2.6%.
   • Same-floor Drainage: Free relocation can be achieved by installing a quick tee, allowing for more flexible layout. However, it is necessary to confirm whether the original drainage system supports same-floor modifications.

II. Key Risks and Precautions

1. Blockage Risk
   Relocating more than 30 cm significantly increases the probability of drainage pipe blockages, especially when using flat pipes. For 110mm flat pipes, relocation should not exceed half a meter; otherwise, they should be replaced with round pipes or the floor should be raised to increase the slope.

2. Waterproofing and Sealing
   All pipe connections must use dedicated sealant or rubber rings. After construction, a 48-hour closed water test should be conducted to ensure no leakage. The floor waterproofing layer should extend at least 30 cm up the wall to prevent moisture penetration and mold.

3. Space and Aesthetics
   An elevated toilet or exposed pipes may affect the overall aesthetics, requiring advance planning of decorative solutions (e.g., concealed cisterns or cabinet遮挡 (Note: '遮挡' means 'concealment' or 'cover', here translated as 'concealment' in context)). Same-floor drainage modifications require confirmation that the floor structure allows for notching or drilling.

III. Professional Recommendations

1. Consult a Professional Team First
   Contact a qualified renovation team or plumber to develop a personalized solution based on the house structure (e.g., cross-floor/same-floor drainage) and pipe material (e.g., PVC/cast iron).

2. Strict Acceptance Standards
   After construction, test the drainage speed (e.g., pour a bucket of water to observe if it drains quickly) and sealing to ensure no odors or leakage.

3. Reserve Maintenance Space
   Pipe layout should consider future maintenance convenience, avoiding completely enclosing drainage pipes within walls or floors.
