How to Make a Portable Toilet

There are mainly two methods for making portable toilets: using a water storage tank and factory prefabrication.

Using a Water Storage Tank

1. Basic Modification: Take out a water storage tank from home and use an angle grinder to split it in half lengthwise. Fix universal wheels at the four corners of a wooden board for easy mobility. Take several wooden strips and firmly attach them to the upper side of the tank using self-tapping screws to increase its height.
2. Building the Door Frame and Walls: Use the angle grinder again to cut an opening on the side of the water storage tank. Install foam strips on both sides of the opening to form the door frame. Take a piece of plastic soft board and insert it between the wooden strips to create raised walls.
3. Installing the Roof and Decorations: Place the upper half of the water storage tank steadily on top of the wooden strips to form the roof. To enhance aesthetics, paint the wooden strips with white waterproof paint.
4. Making a Simple Door: Use foam strips to join two discarded honeycomb wooden boards together to create a simple door.
5. Completing the Drainage and Water Supply Systems: Use a hole-making tool to create a hole at the bottom of the tank and install a drainage pipe to form a floor drain. Make holes on the side and bottom of a plastic tank and connect them with direct fittings. Place the plastic tank on top of the roof to form a small water storage device. Connect the bath heater made of water pipes, install a tee fitting below the water inlet pipe, and connect it to a showerhead. Place the toilet on the hole of the drainage pipe and install the water tank. Secure the toilet with glass glue and connect the drainage pipe to the sewage tank. Horizontally connect a water pipe to the tee fitting on the outlet pipe and extend it to the doorway as the water inlet pipe for the sink, installing corresponding components at the joints.

Factory Prefabrication

Portable toilets are usually factory-prefabricated products, constructed with a steel frame structure through welding. Generally, the bottom is welded with channel steel or I-beams, and the columns are made of square steel, ensuring overall stability and sturdiness. Wall materials are installed on the frame, commonly including color-coated steel sheets, fiberglass, stainless steel, and metal carved panels, each with distinct characteristics. For example, color-coated steel sheets are relatively inexpensive and easy to install; fiberglass is corrosion-resistant; stainless steel is aesthetically pleasing and durable; and metal carved panels are highly decorative. The frame structure meets lifting requirements, facilitating the transportation and installation of portable toilets at designated locations.
