Self-Modified Car Portable Toilet

Self-modifying a car portable toilet can be achieved through the following methods, but proceed with caution and pay attention to safety and compliance:

1. Repurposing a Laundry Detergent Bottle as a Urinal

Materials and Tools: Discarded laundry detergent bottle, handheld drill, water pipe, nut, glue, gasket, mineral water (for testing). Steps:

• Drill a hole in the center of the bottle cap that matches the diameter of the water pipe, install a direct connector, and tighten it securely;
• Slide one end of the sewer hose into the nut, apply glue to the other end, insert it into the connector, add a gasket inside, and tighten the cap;
• Apply glue around the edge of the connector, connect it tightly to the drainage hose, and finally screw the bottle cap back onto the bottle;
• Leak Test: Pour mineral water into the bottle, flip it over, and observe for leaks. Ensure there are no leaks before use. Features: Low cost, simple operation, but limited capacity, suitable for short-distance emergencies.

2. Modifying a Car Armrest Box + Hose into a Portable Urinal

Materials and Tools: Armrest box, hose, discarded plastic bottle, sponge, tape, electric drill. Steps:

• Drill a hole in the bottom of the armrest box, extend the hose into the car's underbody, insert the end into a discarded plastic bottle filled with a sponge, and secure it with tape under the car's pedal;
• Key Precautions:
  • Avoid drilling holes in important vehicle circuits to prevent damage;
  • Replace the water filtration material (such as a sponge) regularly to prevent clogging;
  • Calculate the hose length precisely to avoid excessive length causing entanglement or insufficient length preventing drainage;
  • Test the drainage efficiency after modification to ensure urine flows smoothly into the bottle without backflow. Features: Good concealment, but requires some DIY skills and regular maintenance for long-term use.

3. Utilizing the Trunk Space of MPVs and SUVs to Create an Extended Bathroom

Materials and Tools: Heavy-duty slide rails, screws, portable toilet, enclosed space materials (such as canvas). Steps:

• Use the open trunk door as a roof, enclose the three exposed sides to form a space that matches the height for squatting;
• Install a portable toilet and use heavy-duty slide rails to enable the folding and extension box to slide and bear weight;
• Secure the slide rails to the vehicle body with four screws for easy disassembly. Features: Does not alter the vehicle structure, does not affect driving, provides ample space, suitable for long-distance travel or multiple users, but requires some modification experience.

General Precautions

• Leak Test: All solutions must prioritize leak testing to prevent liquid leaks from damaging the vehicle's interior or electrical circuits;
• Regular Cleaning: For long-term use, regularly clean the container and pipes to prevent bacterial growth;
• Secure the Container: During driving, it is recommended to secure the container in a stable position, such as under the seat, to reduce the risk of shaking;
• Compliance: Some modifications may involve changes to the vehicle structure, so ensure compliance with local regulations;
• Alternative Solutions: If conditions permit, consider purchasing a ready-made portable car urinal, which is designed to be more ergonomic and safer.
