Toilet Bowl Position Relocation

The relocation of a toilet bowl can be achieved through three methods: raising the floor, re-drilling or wall-mounted drainage, and using a toilet offset flange. Details are as follows:

Raising the Floor Method: By constructing a base platform 180 - 200 millimeters high and embedding the drainage pipe, the toilet's drainage outlet can be connected to the new sewer pipe location. This method is suitable for longer relocation distances and offers high layout flexibility. However, it raises the floor level, potentially affecting space aesthetics and usability, increasing safety hazards for the elderly or children, and requiring new flooring materials.

Re-drilling or Wall-mounted Drainage Method: This involves changing from traditional floor drainage to wall drainage, where the drainage pipe runs along the wall and connects directly to the toilet at the new location. This method does not require raising the floor and is relatively simple to construct, especially suitable for small-scale relocations or bathrooms with limited space. However, attention must be paid to whether the wall structure allows for notching, and wall-mounted toilets require a dedicated water tank, potentially increasing initial costs.

Using a Toilet Offset Flange: An offset flange is a specialized fitting that resolves mismatched drainage outlet positions by altering the front-to-back or left-to-right position of the sewer outlet. Common offset distances range from 5 to 10 centimeters, with special cases reaching up to 15 centimeters, although exceeding this range is generally not recommended. Its classifications and parameters are as follows:

• Structural Types: Integrated offset flanges are suitable for short-distance (≤200mm) relocations; oval flat-pipe offset flanges support longer distances (≤500mm), with a pipe diameter of approximately 110mm and a height of 50 - 60mm; in-wall offset flanges can accommodate relocation distances of 190 - 550mm, with a lower height for easy concealed installation.
• Pipe Diameter Specifications: Offset flanges with a diameter of 13.8 centimeters require the top edge of the installed pipe to be flush with the tiled floor; those with a diameter of 11 centimeters have lower installation requirements.

Installation and Usage Precautions:

1. Construction should be carried out before laying floor tiles, ensuring a drainage slope (generally recommended at 5%), with higher slope requirements for longer relocation distances.
2. For long-distance relocations, the pipe should be raised by approximately 5mm for every 100mm moved, possibly requiring the floor to be lowered or raised.
3. When using a flat-pipe offset flange, notching (with a depth of 20 - 40mm) and subsequent floor leveling can reduce the floor elevation increase.
4. Offset flanges increase pipe bends, potentially raising the risk of blockages and causing sewage backflow due to air pressure changes, affecting flushing performance. Therefore, regular pipe maintenance is necessary to ensure smooth flow.
