Homemade Indoor Portable Toilet

A homemade indoor portable toilet can be achieved through the following methods, with specific steps outlined below:

Using a Water Storage Drum

1. Basic Structure Construction
   Use an angle grinder to split the water storage drum in half lengthwise, serving as the main body of the toilet. Fix universal wheels at the four corners of a wooden board for mobility. Attach the wooden board to the top side of the drum using wooden strips and self-tapping screws to increase height for human use.

2. Wall and Roof Construction
   Create an opening on the side of the drum for the door. Install sponge strips to form the door frame and embed plastic soft panels to create raised walls, enhancing privacy. Invert the upper half of the drum onto the top of the wooden strips as the roof and paint the wooden strips with white waterproof paint to improve aesthetics and moisture resistance.

3. Functional Module Installation

   • Drainage System: Create an opening at the bottom of the drum to install a drain pipe, forming a floor drain. Drill holes on the side and bottom of a plastic bucket, install direct connectors, and connect to a simple shower heater made from water pipes.
   • Water Supply System: Install a tee under the inlet pipe, with one end connected to a showerhead and the other extending to the doorway as the inlet pipe for a sink.
   • Toilet and Sewage Disposal: Place a toilet and install a water tank, securing it with glass glue. Connect the drain pipe to a sewage bucket to ensure centralized sewage treatment.
   • Door Construction: Use foam strips to拼接 (assemble) discarded honeycomb wooden boards to make a simple door and drill holes in the door to install connectors for easy opening and sealing.

Using a Water Storage Tank and Pallet

1. Mobile Base Design
   Fix universal wheels at the four corners of a plastic pallet to form a mobile base. Place the water storage tank on the pallet as a sewage storage container.
2. Functional Expansion
   Depending on needs, add modules such as a simple toilet and sink to the pallet and connect them to the water storage tank using hoses to achieve basic sewage disposal functions. This method is structurally simple but requires additional configuration of water supply and sewage disposal systems.

Solar-Powered Mobile Toilet (Overview)

This method is mentioned in the reference information but not detailed. Its core principle likely involves using solar panels to supply power, driving equipment such as water pumps and lights, and combining with a water storage tank and sewage disposal system to achieve environmental protection and energy efficiency. Actual construction requires integrating solar technology, waterproof materials, and lightweight structures, making it suitable for outdoor or long-term use scenarios but with higher technical complexity.

Precautions:

• Plan the space dimensions before construction to ensure the portable toilet harmonizes with the indoor environment.
• Seal the drain pipes and sewage buckets to prevent odor leakage.
• If using electrical equipment (such as a shower heater), install a leakage protection device to ensure safety.
