Mobile Toilet Pipe Laying

Mobile toilet pipe laying mainly involves the pipe arrangement when relocating the toilet, with common methods including floor laying, wall laying, and ceiling laying. The specific choice needs to be combined with the bathroom structure, relocation distance, and family needs.

Floor Laying

• Relocation Device: Suitable for short-distance (100-300mm) relocation. Use a finished elliptical flat pipe (about 60mm in height), which needs to be embedded after chiseling out 20-40mm of the floor slab, connecting the original toilet pipe to the new position. Key Points: The slope of the flat pipe must meet the standard (a height difference of 12mm per meter of pipe) to avoid blockage; 110mm round pipes are preferred as materials, and flat pipes are only used when the tile-laying height is limited.
• Same-Floor Drainage - Floor Slab Lowering: If the bathroom floor slab has already been lowered (concave by 250-350mm), the toilet drainage pipe can be directly arranged, with flexible positioning and no need for additional floor raising.
• Same-Floor Drainage - Floor Slab Raising: Pre-embed the drainage pipe by building a lightweight base platform 180-200mm high, suitable for bathrooms without slab lowering and without elderly family members (to avoid the risk of bumping into steps). Construction Sequence: The floor slab needs to be chiseled out before waterproofing treatment to ensure the integrity of the waterproof layer after pipe pre-embedding.

Wall Laying

• Hidden Cistern: Suitable for long-distance relocation. Install a vertical pipe tee to connect the horizontal drainage pipe to the new position, and build a short wall (180-220mm thick) to enclose the cistern and piping. Advantages: Supports wall-mounted or floor-standing toilets, saving floor space and being aesthetically pleasing; Note: The cistern needs to be installed in advance, and the construction sequence cannot be reversed.

Ceiling Laying

• Inter-Floor Drainage: Requires modifying the drainage pipe at the neighbor's place downstairs, only suitable for situations where the neighborhood relationship is harmonious and the downstairs area is unrenovated. Limitations: It relies on the cooperation of the downstairs neighbor and may damage the ceiling structure downstairs, so it is rarely used in practice.

Key Considerations

1. Material Selection: Preferentially use 110mm round pipes. Flat pipes are only used when the tile-laying height is limited, and the slope must meet the standard.
2. Construction Sequence: For floor laying, the floor slab chiseling needs to be completed before waterproofing; for wall laying, the hidden cistern needs to be installed in advance; for ceiling laying, negotiate with the downstairs neighbor and confirm the construction feasibility.
3. Family Needs: For families with elderly members, it is advisable to avoid raising the floor slab; for long-distance relocation, preferentially choose a hidden cistern; when the neighborhood relationship is tense or the downstairs area is already renovated, use inter-floor drainage with caution.
