Indoor Mobile Toilet Renovation

Indoor mobile toilet renovation can be achieved through methods such as making simple self-made devices, relocating the toilet, or creating space to install independent facilities, depending on the house structure and specific needs.

1. Simple Self-Made Mobile Toilet (Suitable for temporary or low-cost needs)

Using discarded plastic buckets for renovation is a low-cost option, requiring the installation of universal wheels, wooden frame, aluminum sheet partitions, door panels, as well as a toilet tank and drainage pipes. This method is suitable for outdoor or temporary use, but has limitations:

• Insufficient material and structural stability: Discarded plastic buckets have limited load-bearing capacity and are prone to deformation with long-term use; aluminum sheet partitions have poor sound and odor insulation.
• Substandard hygiene standards: Simple devices lack professional waterproof and leak-proof designs, may breed bacteria, and do not meet long-term indoor use standards.
• Single function: Only meets basic toilet needs and cannot integrate modules such as handwashing and ventilation.

2. Toilet Relocation (Suitable for layout adjustment needs)

For unreasonable bathroom layouts, toilet relocation is a core renovation method, and the approach should be selected based on the drainage type:

• Same-floor drainage (sunken bathroom): Pipes can be directly extended or shortened, allowing for flexible and low-cost modifications suitable for short-distance adjustments.
• Inter-floor drainage: Requires the use of a relocator (recommended relocation distance ≤ 2 meters) or raising the floor to re-lay pipes, but excessive relocation can lead to poor drainage and increased risk of blockage.
• Wall-mounted toilet: Hides drainage pipes within the wall, saving space and providing an aesthetically pleasing look, but requires prior planning of water and electricity lines, making renovation more difficult.

3. Creating Space to Install Independent Facilities (Suitable for old residential areas or small apartments)

The “in-house installation” model explored in the renovation of old residential areas in Shanghai offers valuable insights:

• Space optimization: By relocating idle areas (such as moving large wardrobes or utilizing corridor corners), electric toilets or micro-bathroom facilities can be installed to enhance living convenience.
• Technical adaptation: The use of electric toilets reduces reliance on traditional drainage systems and is suitable for inter-floor drainage in buildings where drilling holes is not possible.
• Policy support: Some regions provide subsidies for the renovation of old residential areas, reducing the renovation costs for residents.

Renovation Recommendations:

1. Prioritize evaluating the house structure and drainage type to select an appropriate plan;
2. For long-term use, ensure compliance with hygiene and safety standards and avoid simple devices;
3. For complex renovations (such as drilling holes or raising the floor), consult professionals and complete relevant procedures.
