Construction of Small Mobile Toilets
There are mainly two self-made methods and one factory-prefabricated method for constructing small mobile toilets, as detailed below:

Self-made Method 1: Using a Water Storage Barrel
First, split the water storage barrel in half lengthwise. Fix universal wheels at the four corners of a wooden board for mobility. Increase the height of the barrel using wooden strips and self-tapping screws. Cut an opening on the side of the barrel, install sponge strips to form a door frame, and insert plastic soft boards to create raised walls. Place the upper half of the barrel on top of the wooden strips as a roof and apply white waterproof paint for aesthetics. Use foam strips to拼接 (assemble) discarded honeycomb wooden boards to make a simple door. Cut a hole at the bottom of the barrel and install a drain pipe to form a floor drain. Drill holes on the side and bottom of a plastic bucket, connect direct fittings, and place the bucket on the roof as a small water storage device. Connect a water pipe-made bath heater. Install a three-way fitting below the water inlet pipe and connect a showerhead. Place a toilet and install a water tank, securing it with glass glue. Connect the drain pipe to a sewage barrel. Horizontally connect a water pipe from the three-way fitting of the outlet pipe to the doorway as the water inlet pipe for the sink, and drill a hole in the door to install a fitting.
Self-made Method 2: Using a Water Storage Tank and a Pallet
Fix universal wheels at the four corners of the bottom of a pallet and place a water storage tank retrieved from a garbage station on it. Use an angle grinder to cut along the marked line on the top of the tank to remove one side, creating an open tank. Invert another open-top tank and stack it on the first one, securing the frames of the two tanks with self-tapping screws. Cut a rectangular opening in the frame of the tank and cut the tank body accordingly to form a doorway. Cut a hole in the floor inside the tank, insert a elbow from the bottom upwards and cut a section of water pipe, seal the gaps with glue, and then cut off the excess pipe. Place the toilet over the drain and secure it with glue. Fix a water pipe on the wall clips and install a faucet. Secure a pipe cap with screws below the faucet, connect the water pipe, and then cut a hole below the pipe as the outlet for the drain pipe. Drill a hole in the pipe cap, apply glass glue, and secure a sink made of a stainless steel basin. Connect the water inlet pipe to the toilet tank, connect the shower hose, and install a showerhead bracket and toilet seat. Install a spray-type showerhead made of a water pipe. Bring in wooden boards and fix hinges on the frame of the water storage tank, with the other side of the hinges fixed to the wooden boards to form the bathroom door. Install a door handle on the door.
Factory-Prefabricated Method
Mobile toilets are usually factory-prefabricated products, composed of a frame structure welded from steel. Generally, the bottom is welded using channel steel or I-beams, and the columns use square steel. Wall materials such as color steel plates, fiberglass, stainless steel, and metal carved panels are installed on the wall foundation. The frame structure meets the requirements for lifting.
