Relocation of Toilet Squat Pan

The relocation of a toilet squat pan can be achieved through methods such as demolishing and repaving, using a toilet offset flange, raising the floor, or converting from floor drainage to wall drainage. The appropriate method should be selected based on the relocation distance, spatial conditions, and construction requirements.

1. Demolishing the Original Squat Pan and Repaving
   To completely change the position of the squat pan, the original squat pan and surrounding floor tiles need to be removed, and the layout of the sewage pipes needs to be re-planned. During construction, ensure that the slope of the new pipes is reasonable (usually not less than 2%) to avoid poor drainage. After connecting the pipes, a closed-water test should be conducted to confirm no leakage before repaving the floor tiles. This method is suitable for situations where the relocation distance is large or the original pipe layout is unreasonable. However, the construction period is relatively long, the cost is high, and the original floor structure needs to be destroyed.

2. Adjusting the Position Using a Toilet Offset Flange
   A toilet offset flange is a commonly used tool for short-distance relocation of squat pans. It achieves positional offset by extending the sewage pipe. The center distance of a bias-type toilet offset flange can be adjusted by 6-7 centimeters. During installation, holes need to be drilled in the floor for fixation to ensure that the bottom of the offset flange is flush with the floor and is completely covered after tiling. The standard center distance of a squat pan from the wall is 42 centimeters, and this distance should be maintained after relocation to match the installation size. It is recommended to use 110-millimeter flat or round pipes, which have a larger inner diameter and can reduce the risk of blockage. This method is simple in construction and low in cost but is only suitable for short-distance relocation (generally not exceeding 10 centimeters).

3. Raising the Floor and Pre-burying the Sewage Pipe
   For long-distance relocation (exceeding 20 centimeters), a concrete base with a height of 180-200 millimeters can be built, and a new sewage pipe can be pre-buried with a proper slope. This method requires raising the bathroom floor, which may affect the installation of the door frame and ease of use but can solve the problem of long-distance drainage. During construction, pay attention to the waterproofing treatment at the joint between the base and the original floor to avoid structural damage caused by water seepage.

4. Converting from Floor Drainage to Wall Drainage
   Converting from traditional floor drainage to wall drainage can avoid raising the floor. The pipes are laid along the wall to the main sewage pipe, with relatively low construction difficulty and higher space utilization. This method requires confirming that the wall is a non-load-bearing wall or that it can meet the load-bearing requirements of the pipes through reinforcement. A wall-mounted squat pan requires a dedicated water tank, and after installation, the tightness of the pipes should be checked to prevent odor leakage.

Precautions:

• Before relocating the squat pan, confirm that the property management allows changes to the drainage pipes to avoid damaging the building structure.
• During construction, strictly follow waterproofing specifications, especially at the joints between the pipes and the floor and wall.
• If changes to the main sewage pipe are involved, report to the relevant department in advance to ensure compliance with drainage standards.
