Toilet Relocation: Raising by 45 cm

Whether it is reasonable to raise the toilet by 45 cm during relocation depends on a comprehensive assessment of the relocation type, bathroom structure, and drainage requirements. The specific analysis is as follows:

1. Raising Range for Squat Toilet Relocation When installing a squat toilet, the height of the raised floor typically ranges from 30 cm to 45 cm. If the squat toilet needs to be raised to 45 cm after relocation, the following conditions must be met:

• Drainage Slope Requirements: After raising, ensure that the slope of the drainage pipe meets the standard (generally not less than 1%) to prevent sewage backflow or blockage.
• Space Height Limitations: Sufficient clear height (usually not less than 2.2 meters) must be reserved to avoid a压抑 (oppressive) feeling during use or affect ventilation.
• Structural Load-Bearing: The raised part must be constructed with bricks or concrete pouring, and it is necessary to confirm whether the load-bearing capacity of the floor slab meets the standard.

2. Raising Range for Squat Pit Relocation When relocating a squat pit, the height of the raised floor typically ranges from 10 cm to 30 cm. If it needs to be raised to 45 cm, the following issues may arise:

• Excessive Relocation Distance: When the squat pit relocation exceeds 1 meter, raising it too high can easily result in insufficient bending radius of the drainage pipe, increasing the risk of blockage.
• Usability Convenience: Excessively high steps may pose safety hazards to the elderly or children, requiring the installation of anti-slip measures or handrails.

3. Special Cases of Toilet Relocation If the toilet relocation involves a distance of 2.5 meters:

• Non-sunken Bathroom: It needs to be achieved by raising the floor or modifying the pipeline under the floor slab. Raising it by 45 cm may meet the drainage requirements, but it is necessary to simultaneously modify the height of the door frame (to avoid collision when opening the door) and adjust the indoor floor level.
• Sunken Bathroom: The pipeline can be directly laid within the sunken tank without raising the floor, but it is necessary to confirm whether the depth of the sunken tank is sufficient (usually not less than 30 cm).

4. Key Points for Comprehensive Assessment

• Drainage Pipe Layout: Prioritize the shortest relocation path, reduce the number of elbows, and ensure a reasonable slope.
• Bathroom Height: If the original floor height is relatively low (e.g., ≤ 2.6 meters), raising it by 45 cm may result in insufficient clear height, requiring careful design.
• Relocation Method: When using a relocator, the raising height must match the relocation distance (approximately 5-10 cm of raising per meter of relocation); if a wall-mounted toilet is used, the need for raising the floor can be reduced.

Conclusion: Raising the toilet by 45 cm during relocation may be reasonable for squat toilet installation or long-distance toilet relocation, but it is necessary to strictly assess drainage, load-bearing, and usage safety. It is recommended to have a professional plumber conduct on-site measurements before determining the plan.
