How to Make a Portable Toilet by Yourself

You can choose different methods to make a portable toilet based on your needs and materials. Common and feasible ways include using a water storage tank to make a complete structure and using common items to make a simple emergency solution. Here are the specific steps:

Making a Complete Portable Toilet Using a Water Storage Tank

1. Basic Structure Construction

   • Use an angle grinder to split the water storage tank vertically in the middle, forming two half-tank structures as the main frame of the toilet.
   • Install universal wheels at the four corners of the wooden board to ensure mobility. Fix wooden strips to the upper edge of the tank with self-tapping screws to increase the structural height for human use.
   • Cut an entrance on the side of the water storage tank, install sponge strips to form a door frame, embed plastic soft boards to create raised walls, and invert the upper half of the tank onto the top of the wooden strips as a roof to form an enclosed space^[2].

2. Functional System Installation

   • Drainage System: Drill holes at the bottom of the tank to install a drain pipe as a floor drain. Drill holes on the side to connect interfaces, drill another hole at the bottom to install an interface and place a plastic bucket to form a small water storage device. The drain pipe should extend to an external sewage tank^[2].
   • Water Supply System: Install a simple shower made of water pipes. Install a tee under the water inlet pipe and connect a showerhead. Place a toilet and install a water tank, and fix the toilet with glass glue to prevent leakage^[2].
   • Hand-washing Facility: Connect a water pipe horizontally from the tee of the outlet pipe and extend it to the entrance as the water inlet pipe for a hand-washing basin, and drill a hole in the door to install an interface^[2].

Making a Simple Portable Toilet Using Common Items (Emergency Solution)

1. Urination Emergency Solutions

   • Diaper Filling Method: Take out the cotton and absorbent particles from diapers and put them into a sealed plastic bag. Use their high water absorbency to absorb urine and prevent side leakage^[4].
   • Direct Use of Ready-made Products: Purchase portable toilets designed specifically for children on the market. These products usually have a simple structure and are easy to carry^[4].

2. Defecation Emergency Solutions

   • Large Plastic Bag Method: Lay a large plastic bag in a vehicle or a fixed container, seal it and discard it after defecation, which is suitable for temporary situations^[4].
   • Cardboard Box Combination Method: Use a small cardboard box, line the bottom with a plastic bag, and surround it with cardboard on all sides to form a simple structure. Pay attention to fixing it to prevent tipping^[4].

3. Water Absorbency Enhancement Tips Add a small packet of superabsorbent polymer to the sealed plastic bag. When it comes into contact with water, the outer packaging will automatically melt, quickly solidifying the excrement and reducing odors and leakage risks^[4].

Precautions: When making a toilet with a water storage tank, ensure that the cutting edges are smooth to avoid cuts. The connections of the drain pipes should be tightly sealed to prevent leakage. Simple solutions are only suitable for temporary emergencies. For long-term use, consider hygiene and environmental protection issues.
