How to Build a Simple Mobile Toilet

There are mainly three methods for building a simple mobile toilet: using a water storage barrel, using a water storage tank and a pallet, and installing a ready-made unit without civil engineering.

Building with a water storage barrel: First, take out a water storage barrel from home and split it in half lengthwise with an angle grinder. Fix universal wheels at the four corners of a wooden board for easy mobility. Attach wooden strips to the upper side of the barrel with self-tapping screws to increase its height. Use the angle grinder to cut an opening on the side of the barrel and install sponge strips on both sides of the opening to form a door frame. Insert plastic soft boards between the wooden strips to create an elevated wall. Place the upper half of the barrel on top of the wooden strips as a roof and paint the wooden strips with white waterproof paint. Make a simple door by joining waste honeycomb wooden boards with foam strips. Cut a hole at the bottom of the barrel and install a drain pipe to form a floor drain. Cut holes on the side and bottom of a plastic bucket and install direct connectors. Place the plastic bucket on the roof as a small water storage device. Connect a water pipe-made bath heater, install a three-way connector below the inlet pipe and connect a showerhead, place a toilet and install a water tank, and fix the toilet with glass glue. Connect the drain pipe to a sewage bucket, horizontally connect a water pipe from the three-way connector of the outlet pipe to the door as the inlet pipe for a hand-washing basin, and cut a hole on the door and install a connector.

Building with a water storage tank and a pallet: Take out a plastic pallet and fix universal wheels at its four corners. Place a water storage tank retrieved from a garbage station on the pallet and use an angle grinder to cut along the marked line on the top of the tank to remove the top and form an open tank. Invert another open-top water storage tank and stack it on the first tank, and fix the outer frames of the two tanks with self-tapping screws. Cut a rectangular opening on the outer frame of the tank and cut the tank body according to the corresponding size to form a doorway. Cut a hole on the internal floor of the tank, insert an elbow from the bottom upwards and connect a water pipe, seal the gaps with glue, and cut off the excess water pipe. Align the toilet with the drain hole and fix it with glue. Fix a water pipe on the wall buckles and install a faucet, fix a pipe cap with screws below the faucet, connect the water pipe and cut a hole at the bottom as the outlet for the drain pipe. Cut a hole on the pipe cap, apply glass glue, and fix a hand-washing basin made of a stainless steel basin. Connect the inlet pipe to the toilet water tank, connect the shower hose, install a shower bracket and a toilet seat, and install a 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 a door, and install a door handle on the door.

Installing a ready-made unit without civil engineering: With a pile of parts on the ground, it's like building with building blocks. Fix them through upright columns and splicing, and everything fits perfectly in one go.
