Mobile Toilet Renovation Plan

The mobile toilet renovation plan should be selected based on the drainage method and requirements of the bathroom. Here are some common plans and key points:

1. Toilet Displacement Device Method Suitable for small-scale and short-distance displacement, usually not exceeding 40 centimeters (some say it should not exceed 100mm). Its advantages include minimal modification and low cost, but it may affect the flushing effect and increase the risk of blockage. During construction, a slope of 1%-3% should be reserved to ensure smooth drainage. The thickness of the ground slot is generally 20-40mm, and the ground height can be maintained unchanged through the cement mortar layer. If it is an interlayer drainage system, since the floor slab cannot be excavated, the floor slab needs to be raised to install the displacement device.

2. Ground Elevation Method By building a base platform 180-200 millimeters high to embed the sewage pipe, it is suitable for situations where the displacement distance is relatively long. This method allows for flexible layout but significantly raises the ground level, affecting aesthetics and ease of use (such as requiring steps to enter and exit the bathroom). During construction, ensure the structural stability of the base platform and proper waterproofing.

3. Floor Drain to Wall Drain Conversion Method Convert the floor drain pipe to run along the wall, eliminating the need to raise the ground and making the pipes easy to conceal. The toilet can only be moved to the adjacent wall of the sewage riser, not to the opposite wall. After modification, the risk of toilet blockage is reduced, and it is applicable to both same-floor and interlayer drainage systems. However, consent from the downstairs residents is required, and waterproofing needs to be redone. For wall drain conversion, a false wall needs to be built, and during renovation, it can be combined with niche design to increase storage space.

4. Left-Right Sewage Discharge Toilet Method Connect a tee to the main sewage pipe and choose a left-right sewage discharge toilet. To maintain aesthetics, the toilet should be placed as close to the main sewage pipe as possible. If a longer displacement distance is required, pipes can be concealed by building a ground platform, a half-wall, or a niche, but attention should be paid to space utilization and visual coordination.

5. Wall-Mounted Toilet Method Similar to connecting a new tee to the main sewage pipe, a wall-mounted toilet design is adopted. This method can hide the water tank and pipes, saving space and facilitating cleaning. However, ensure that the load-bearing capacity of the wall meets the requirements and plan the water and electricity lines in advance.

6. Same-Floor Drainage Displacement Method For sunken bathroom structures (where the floor slab is at a lower position), pipes can be arranged arbitrarily within the sunken layer with fewer displacement restrictions. For non-sunken structures, displacement can also be achieved by lengthening or shortening the pipes, but ensure a reasonable slope to avoid poor drainage.

7. Downstairs Pipe Modification Method Applicable to interlayer drainage systems, it strictly requires the consent of the downstairs residents and the property management. Professional personnel modify the pipes on the ceiling downstairs. This method involves thorough modification but requires coordination among multiple parties and has higher construction risks, so it should be chosen with caution.
