Indoor Mobile Small Toilet Design

The design of indoor mobile small toilets can be achieved through the modification of water storage barrels or space optimization solutions, with the former focusing on mobility and the latter on enhancing functionality in fixed spaces.

I. Water Storage Barrel/Tank Modification Plan (Mobile Design)

1. Basic Structure Construction
   Split the water storage barrel horizontally in the middle to form two halves. The lower half serves as the main body of the toilet, with universal wheels fixed at the bottom for mobility. The upper half acts as the roof, connected to the lower half via hinges or buckles for easy opening and closing. If using a water storage tank, a support plate can be directly installed on top of the tank, with universal wheels added to the bottom of the plate to form a simple mobile platform.

2. Wall and Door Frame Installation
   Cut an opening on the side of the lower half of the barrel, reinforce the edges with wooden strips or metal frames, and insert plastic soft panels or waterproof cloth as walls. The door frame can be designed as a sliding or folding type to reduce space occupation. For higher stability, a support frame can be built inside the barrel using wooden strips, and then the wall materials can be fixed.

3. Sewage and Drainage System
   Install a drainage pipe at the bottom of the barrel, connecting the toilet's sewage outlet to an external sewage barrel (such as a sealed plastic barrel). The toilet can be a portable folding toilet or a fixed toilet, ensuring that the sewage outlet aligns with the drainage pipe. Extend the water pipe to the door position and install a simple sink, using a water pump or gravity to supply water for hand washing.

4. Additional Function Configuration
   Install a bathroom heater or a small heating lamp on the inner side of the roof to enhance comfort. Set up hooks or small shelves on the walls to store toilet paper, cleaning agents, and other items. If space permits, a storage cabinet can be added outside the barrel to store spare sewage barrels or cleaning tools.

II. Space Optimization Plan (Fixed Small Bathroom)

1. Vertical Space Utilization
   Create niches in the walls with a recommended depth of 15-20 centimeters to store bottled items such as shampoo and body wash. Install ultra-thin storage racks or pegboards on the wall behind the door to hang long-handled tools like mops and brooms, avoiding ground space occupation.

2. Functional Zone Adjustment
   Move the sink outside the bathroom and achieve dry-wet separation through partitions or glass doors to reduce internal congestion. If space is limited, stack the sink and washing machine or choose a mini sink (width ≤ 50 centimeters).

3. Wall and Door Design Optimization
   Install pegboards or hooks to store frequently used items such as toothbrushes and towels. Reduce the size of the bathroom door (e.g., from 80 centimeters to 60 centimeters) to increase available wall space. Install the showerhead opposite the toilet or connect it to the sink to form a composite functional area, saving shower space.
