Mobile Toilet Renovation

Mobile toilet renovation can be achieved through methods such as using a toilet offset connector for short-distance adjustments, raising the floor to re-lay pipes, converting to a wall-mounted toilet or drilling holes in the floor slab, and manually converting a squat toilet to a sitting toilet. Details are as follows:

1. Using a toilet offset connector for short-distance adjustments
This method is suitable for situations where the original pit distance does not match the toilet size. For example, when the actual pit distance is 400mm but the water outlet is relatively close, a toilet offset connector can be used to change the pit distance to 350mm or 300mm and install the toilet with a backward tilt. During operation, in a bathroom with a sunken tank, first cut off the tiles, remove the dust layer to the waterproof layer, place the toilet offset connector in position, and then use leak-stopping powder to redo the waterproofing and level the floor. This method is simple to construct, but the offset distance generally should not exceed 300mm; otherwise, it may affect the drainage effect.

2. Raising the floor to re-lay pipes
As one of the main methods for toilet relocation, it requires raising the original floor to a certain height (usually 10-15cm), re-laying the drainage pipes, and adjusting the slope (it is recommended that the slope be ≥2%) to ensure smooth discharge of sewage. After construction, the waterproof layer needs to be redone, and the pipe joints should be sealed with sealant or cement mortar to prevent leakage. Note: Raising the floor may affect the overall floor height of the bathroom, and improper pipe slope may lead to blockages and even complaints from downstairs residents.

3. Converting to a wall-mounted toilet or drilling holes in the floor slab
A wall-mounted toilet transfers the sewage outlet to the wall by hiding the water tank and drainage pipes, allowing for flexible position adjustment. If long-distance relocation is required, holes can be drilled in the floor slab (with property management permission), and the drainage pipes can be directly connected to the sewage pipes downstairs. Both methods require strict control of the pipe slope (it is recommended that the slope for a wall-mounted toilet be ≥1.5%) and sealing, and the waterproof layer should be redone. Risk warning: Drilling holes in the floor slab may damage the structural safety and should be carried out by professionals.

4. Manually converting a squat toilet to a sitting toilet
This method is suitable for users with a limited budget and strong hands-on ability. The steps include: prying up the squat toilet and the surrounding tiles, extending the sewage pipe with PVC pipes; resetting the squat toilet, building red bricks along the edges and filling them with sand for fixation; smoothing the outer side of the red bricks and the floor with cement mortar, and re-laying the tiles; installing a discarded toilet seat (reinforced with 502 glue) and making a self-made flushing water tank (such as a repurposed paint bucket). Note: This method may affect the drainage efficiency, and the self-made water tank has a risk of leakage. It is recommended to be used only as a temporary solution.
