The mobile toilet flush tank can be achieved through homemade methods or by purchasing ready-made products. The homemade option offers flexibility but requires hands-on skills, while the price of ready-made products varies significantly depending on the brand, material, and functionality.

Homemade Solutions

1. Water Storage Tank + Pallet Solution

   • Basic Structure: Use a recycled water storage tank as the core component, and install universal wheels at the bottom for mobility. Cut an opening at the top of the tank using an angle grinder, then invert and stack two open tanks and secure them with self-tapping screws to form a closed space.
   • Functional Modules:
     • Sewage System: Drill a hole in the interior floor and insert an elbow to connect to a water pipe. Install a toilet and secure it in place; connect the toilet tank to a showerhead via a shower hose to enable flushing and simple showering functions.
     • Washing System: Fix a water pipe to the wall with clips and install a faucet, connecting a stainless steel basin below as a handwashing sink; extend a three-way outlet pipe horizontally to the doorway to create an independent handwashing area.
     • Detail Optimization: Cut a rectangular opening as the doorway, make a door using wooden boards and hinges, and install a door handle to enhance convenience.

2. Water Storage Bucket Cutting Solution

   • Structural Modification: Split a water storage bucket in half, fix universal wheels at the bottom, add height to the top with wooden strips, then cover the upper half of the bucket as a roof, and apply white waterproof paint to improve aesthetics.
   • Functional Modules:
     • Sewage System: Drill a hole at the bottom of the bucket and install a drain pipe to form a floor drain, connecting to a sewage bucket; place a toilet and install a tank, securing it with glass glue to prevent leakage.
     • Washing and Heating: Drill a hole on the side and connect a three-way fitting, extending it to the shower and handwashing sink inlet pipes respectively; make a simple bathroom heater using a water pipe, and create a small water storage device by placing a plastic bucket on the roof to meet hot water needs.
     • Door and Wall: Build a door frame with sponge strips, insert plastic soft boards to form walls;拼接（这里英文用assemble更合适） assemble a door using foam strips and discarded honeycomb wooden boards to reduce material costs.

It is recommended to refer to detailed tutorials and equip with professional tools.
