Toilet Relocation in Row House

The method for relocating the toilet (toilet relocation) in a row house should be selected based on the drainage type, as detailed below:

I. Same-Floor Drainage (Sunken Bathroom)

If the bathroom floor is approximately 40 centimeters lower than the floor level, and the drainage pipes are located within your own bathroom, modifications are relatively flexible:

1. Direct Pipe Adjustment: Achieve relocation by extending or shortening the existing drainage pipes. This operation is simple and cost-effective.
2. Wall-Mounted Toilet: Connect the toilet's drainage directly to the main vertical pipe, suitable for scenarios where the distance to the sewer pipe is close. However, confirm in advance whether the position of the vertical pipe allows for connection.

Advantages: No need to damage the floor structure, modifications are controllable, and there is no impact on the downstairs neighbors. Note: Ensure the tightness of the pipes to avoid future leakage.

II. Cross-Floor Drainage (Drainage Pipes Pass Through the Floor)

This type of drainage is more difficult to modify and requires selecting a plan based on the relocation distance and actual conditions:

1. Toilet Relocator
   • Suitable Scenarios: Short-distance relocation (for integrated types, it is recommended to be ≤20 centimeters; for side-pipe types, ≤50 centimeters).
   • Operation Points: Reserve at least a 0.5-centimeter slope for every 10 centimeters of pipe to ensure smooth drainage; if the relocation exceeds 10 centimeters, use a straight-drain toilet to reduce the risk of blockage.
2. Floor Drain to Wall Drain Conversion
   • Method: Connect the toilet's drainage pipe to the wall adjacent to the sewage vertical pipe and hide the pipe by building a false wall.
   • Advantages: Less prone to blockage after modification and can be combined with niche design to increase storage space.
   • Limitations: Occupies some wall space and may affect the bathroom layout.
3. Negotiate Pipe Modification with Downstairs Neighbors
   • Method: Drill holes in the floor and rearrange the pipes, requiring the consent of the downstairs neighbors.
   • Reality: In practice, 99% of neighbors may refuse, so carefully evaluate feasibility.
4. Raise the Floor
   • Method: Reserve a drainage slope by raising the floor, usually requiring a raise of 10-15 centimeters.
   • Disadvantages: Affects comfort of use, increases the risk of tripping, and is generally not recommended.

III. General Precautions

1. Prioritize Short-Distance Modifications: Excessive relocation distance can easily lead to poor drainage, and it is recommended to keep it within 50 centimeters.
2. Waterproofing: After modifying cross-floor drainage, perform double waterproofing on the floor and pipe connections to avoid leakage to the downstairs.
3. Drainage Type Selection: If conditions allow, prioritize same-floor drainage, which can significantly reduce the difficulty and risk of modifications.

Summary: Toilet relocation should be comprehensively decided based on the drainage type, relocation distance, and actual conditions. Same-floor drainage modifications are more flexible, while cross-floor drainage requires focusing on solving drainage slope and waterproofing issues.
