Mobile Shower and Toilet

Mobile showers and toilets can be realized through simple DIY or professional design, with common solutions including bucket-and-board combinations, storage tank and pallet modifications, and prefabricated structures. Here are the specific implementation methods and technical points:

1. Bucket and Board Combination Solution
This solution uses discarded buckets as the core material, achieving functional integration through structural modifications. First, prepare 4-6 plastic buckets with a capacity of over 20L each. Choose two of them as water storage units, cut one into the shape of a toilet seat and install a sealing ring, and use the remaining buckets for collecting shower wastewater. The boards should be multi-layer boards treated with anti-corrosion, cut into a base plate of 50cm×80cm and installed with four universal wheels, with door openings reserved on the side panels. When making, pay attention to the following:

• Drainage System: Drill holes at the bottom of the toilet bucket and connect it to a PVC drainage pipe, with the end connected to a wastewater collection bucket. The floor drain in the shower area should be treated for odor prevention.
• Shower Device: Connect a booster pump to the water storage bucket, lead it to an adjustable-height shower bracket through PPR pipes, and use a cold-hot mixing valve for water temperature adjustment.
• Sealing Treatment: Use waterproof glass glue to seal all connection parts, and install rubber sealing strips on the door frame to prevent odor diffusion.

2. Storage Tank and Pallet Modification Solution
This solution utilizes the pressure resistance of industrial-grade storage tanks and is suitable for long-term use scenarios. Prepare two 200L plastic storage tanks, one as a toilet water tank and the other modified into a shower room. The modification points include:

• Structural Reinforcement: Weld angle steel frames at the bottom of the plastic pallets and install six heavy-duty universal wheels to ensure load-bearing capacity.
• Functional Zoning: Cut the storage tanks vertically, retaining 30cm at the top as the water storage area, and cut door openings at the bottom and install folding doors.
• Water and Electricity Integration: Use a siphon-type water-saving toilet, with a float valve installed in the water tank for automatic water replenishment; equip the shower area with an instant electric water heater, and the circuit should be waterproofed.

3. Prefabricated Structure Solution
Professional designs usually adopt modular structures, such as the Apple Cabin design by Dezhou Hongtu Metal Products. This solution includes:

• Main Structure: Use galvanized steel frames with Great Wall board exterior walls, providing wind and earthquake resistance.
• Functional Layout: The interior is divided into two 1.2m×1.5m squatting toilets and one shower room, with PVC partitions for wet-dry separation.
• Supporting Systems: Integrate a septic tank, solar water heating system, and intelligent ventilation device, suitable for batch deployment in scenic spots, construction sites, and other scenarios.

Implementation Recommendations:

• For simple solutions, regularly check the aging of sealing parts and recommend replacing them every six months.
• For professional designs, reserve inspection ports for easy pipeline maintenance.
• All solutions must comply with the requirements of the 'Urban Public Toilet Design Standard' regarding lighting, ventilation, and sewage discharge.
