Self-Modification of Mobile Toilet

Self-modifying a mobile toilet can be achieved through various methods. Here are some specific and feasible modification approaches:

Modification Using a Water Storage Barrel

First, split the water storage barrel in half with an angle grinder and fix universal wheels at the four corners of a wooden board for easy mobility. Then, use wooden strips and self-tapping screws to increase the height of the barrel. Cut an opening on the side of the barrel, install sponge strips to form a door frame, and insert plastic soft boards to create an elevated wall. Place the upper half of the barrel on top of the wooden strips as a roof and apply white waterproof paint to enhance its appearance. Drill a hole at the bottom of the barrel to install a drain pipe as a floor drain, and drill a hole on the side to connect a direct fitting. Place a plastic bucket on the roof as a small water storage device. Use a water pipe to make a bath heater, install a tee fitting below the inlet pipe and connect a showerhead, place a toilet and install a water tank, secure the toilet with glass glue, connect the drain pipe to a sewage bucket, and horizontally connect a water pipe to the tee fitting on the outlet pipe extending to the doorway as the inlet pipe for a sink. This method offers relatively comprehensive functions, covering basic needs such as bathing and using the toilet, but the modification process is relatively complex and requires certain hands-on skills and tools.

Modification Using a Water Storage Tank and a Pallet

Fix universal wheels at the four corners of the bottom of a plastic pallet using tools, and then combine it with a water storage tank to form a mobile toilet. This method is relatively simple and has a low cost, but its functions are relatively single, mainly suitable for simple toilet needs, lacking other functions such as bathing.

Modification of a Mobile Toilet Using Waste Tiles

First, place the toilet on the tiles and draw red marking lines along the edge of the toilet. After moving the toilet away, use an angle grinder to cut out a rectangular tile piece slightly larger than the bottom of the toilet along the marking lines. Turn the rectangular tile over and place universal wheels at the four corners. Draw marking points with a marker pen, drill screw holes with an electric drill, insert screw rods, and screw on nuts to fix the universal wheels. Then, use the angle grinder to cut off the protruding screw rods on the back of the tile. Put the toilet back on the tiles, draw marking lines along the edge of the toilet, mark the position of the sewage outlet at the bottom of the toilet connecting to the sewer, and insert and fix a hose from the bottom of the tiles. Apply white cement along the marking lines on the tiles, place the toilet according to the marking lines, then install the water tank, screw on plastic fasteners, cover the water tank lid, install the toilet seat, put the sewage hose into the drain pipe, and connect the water inlet pipe to the water tank. This method makes full use of waste materials and has a low cost, but the modification process requires certain skills and patience.

Modification of a Mobile Squat-Type Toilet Using PVC Pipes

Prepare 4 plastic caps, drill small holes through them with an electric drill, insert screws from the outside, screw on nuts and wheel combinations to fix them, and cut 4 short sections of straight pipes to closely connect with the plastic caps. Drill circular holes through the sides of some tees, assemble the two side bracket parts, insert and embed straight pipes into the reserved holes of the tees to form a base frame, and install wheel covers. Extend the straight pipes vertically upwards along with the elbow reducers on both sides, install wooden footrests and a base, and fix sturdy wooden boards on the sides and top as well as a backrest at the rear with screws. Install tightened plastic pipes as handrails at the four front corners, use hoses to edge the front of the wooden board, and cut a circular hole of the required size in the middle of the wooden board. The toilet modified by this method has a relatively simple structure and is easy to move, but its comfort and functionality may be relatively weak.
