Indoor Refitted Mobile Toilet

Indoor refitted mobile toilets can be achieved through creative design and reasonable planning, but strict compliance with regulations and attention to technical details are required. Here are specific methods and considerations:

I. Common Refitting Solutions

1. Refitting a Movable Toilet from Waste Tiles

   • Material Preparation: Select waste tiles and cut them into the shape of a toilet base, ensuring the size fits ergonomics (e.g., the seat width is approximately 30-40 centimeters).
   • Installing Universal Wheels: Fix universal wheels with brakes at the four corners of the base for easy movement and stability.
   • Securing Toilet Components: Connect a finished toilet tank or a simple flushing device (such as a pressure tank) to the base, ensuring tightness to prevent leakage.
   • Drainage Design: If space allows, connect a hose to the existing drainage pipe; if independent use is required, equip a large-capacity sewage tank and clean it regularly.

2. Combination Solution of Water Storage Tank and Support Plate

   • Structural Construction: Use a waterproof support plate (such as PVC board or anti-corrosion wood) as the base, and place a water storage tank (recommended capacity ≥ 50 liters) on top as the flushing water source.
   • Functional Integration: Install a simple toilet (such as a folding toilet or a plastic bucket with a seat ring) on the support plate, and achieve flushing through a water pump or gravity.
   • Concealed Treatment: Use curtains or partitions to divide the space and enhance privacy; the water storage tank can be hidden behind cabinets or decorative panels.

II. Key Technical Considerations

• Toilet Type Selection: Avoid using siphon toilets after relocation, as they rely on gravity drainage and have high requirements for pipe slope (usually ≥ 2%). If the pipe conditions are poor (e.g., pipe diameter < 10 centimeters or there are bends), prioritize using straight-flush toilets to reduce the risk of blockage.
• Waterproofing and Moisture Resistance: The floor of the refitted area should be coated with waterproof paint (such as polyurethane waterproof paint), and the wall waterproofing height should be at least 1.8 meters; if wooden materials are used, moisture-proof treatment should be carried out (such as painting with wood paint or laying moisture-proof film).
• Ventilation Design: Install an exhaust fan or a small fresh air system to avoid odor accumulation; if the space is enclosed, air fresheners or activated carbon can be used regularly to absorb odors.

III. Regulations and Compliance Requirements

• Space Usage Restrictions: According to the 'Measures for the Administration of Interior Decoration of Residential Buildings', it is prohibited to convert rooms without waterproof requirements (such as bedrooms and living rooms) or balconies into bathrooms, otherwise fines may be imposed and restoration to the original state may be required.
• Protection of Neighbors' Rights and Interests: The refitting should not affect the waterproof layer or drainage system of the downstairs residents. It is necessary to communicate with the property management in advance and confirm the pipe layout; if public drainage pipes are involved, ensure that the drainage volume after refitting does not exceed the original design load.

IV. Maintenance and Safety Recommendations

• Regularly check the brake devices of the universal wheels to avoid sliding and tipping over;
• The sewage tank should be cleaned and disinfected daily to prevent bacterial growth;
• The circuit layout should be kept away from water sources, use waterproof sockets and install leakage protectors.
