Homemade Mobile Toilet Renovation Plan

The homemade mobile toilet renovation plan should be selected based on the usage scenario, needs, and hands-on skills, and can be divided into three categories: simple temporary construction, specific-need renovation, and handmade construction.

I. Simple Temporary Toilet Construction (Short-term/Emergency Scenarios)

1. Portable Toilet
   Suitable for camping or short trips, consisting of a foldable stand and disposable garbage bags. Unfold the stand, insert a dedicated garbage bag, and dispose of it by sealing the bag after use. Advantages include portability and ease of carrying, but frequent replacement of garbage bags is required, and there is no privacy protection.

2. Bucket Toilet

   • Materials Preparation: A 10-20 liter plastic bucket with a lid, thick garbage bags, absorbent materials (such as cat litter or sawdust), toilet paper, disinfectant, and optionally, a simple tent or screen.
   • Assembly Steps: Line the bucket with a garbage bag and secure it, place 2-3 cm of absorbent material at the bottom, place toilet paper and disinfectant, install a handle or stand beside the bucket, and finally, enclose a private space with a tent or screen. Absorbent materials can reduce odors, but regular cleaning of bucket residues is required.

3. Tent Toilet
   Combines a small tent with a portable toilet or bucket setup, providing privacy through the tent, suitable for outdoor activities. Ensure the tent is well-ventilated to avoid stuffiness inside and secure the tent to prevent tipping over.

II. Renovation Plans for Specific Needs

1. Urination Emergency Plan

   • Diaper Filling Method: Remove cotton and absorbent particles from diapers, insert them into a sealed plastic bag, and use high absorbency to quickly absorb urine and prevent leakage, costing about 1 yuan.
   • Direct Use of Ready-made Products: Purchase mobile toilets designed specifically for children (costing about 4 yuan each), suitable for frequent use scenarios. Ready-made toilets are structurally stable but require regular cleaning.

2. Defecation Emergency Plan

   • Large Plastic Bag Method: Use a large garbage bag to line a fixed container and dispose of it by sealing it after defecation. Ensure the plastic bag is intact and dispose of it promptly after sealing.
   • Cardboard Box Combination Method: Line the bottom of a small cardboard box with a plastic bag to form a barrier structure, protecting privacy and facilitating cleaning. The cardboard box must be securely fixed to prevent tipping over.
   • Enhanced Absorbency Technique: Add superabsorbent polymers (such as those found in sanitary napkins/diapers) to a sealed plastic bag, which quickly solidify excreta upon contact with water, reducing odors and leakage risks. Keep superabsorbent polymers out of reach of children to prevent ingestion.

III. Handmade Simple Toilet (Suitable for Users with Hands-on Skills)

1. Basic Structure
   Excavate a toilet drain and connect it to the sewer to ensure direct discharge of excreta into the municipal sewer network; erect four pillars as a frame, enclose the walls with tiles or waterproof panels, and lay non-slip floor tiles on the ground. Ensure the structure is stable and meets hygiene standards.

2. Creative Design
   Draw inspiration from children's toy toilets to create a hinged toilet seat, hidden storage cabinets, etc.; ensure there are no hygiene dead zones and the structure is stable (e.g., use metal hinges to fix the toilet seat). Creative designs can enhance the user experience but avoid complex structures that hinder cleaning.

Precautions: Seal plastic bags after use and dispose of them promptly to avoid prolonged storage; ensure cardboard structures are securely fixed; keep superabsorbent polymers out of reach of children to prevent ingestion.
