Rural Mobile House Toilet Design

The design of toilets in rural mobile houses should take into account structural stability, functional practicality, and ease of use. Common design points are as follows:

1. Structural Design and Material Selection The main frame is primarily made of lightweight metal materials, such as iron sheet 02 profiles, which provide structural support while reducing the overall weight for easy transportation and assembly. The exterior is covered with color-coated steel plate trim, and the interior sandwich layer is filled with 5mm thick foam material to achieve thermal insulation and adapt to different climatic conditions. The top and bottom adopt a separated design, and the loose-parts shipping mode allows for flexible adjustment of transportation methods. During on-site assembly, they are fixed with bolts or buckles to simplify the construction process. Attention should be paid to the rust prevention treatment of the metal frame, and the joints of the color-coated steel plate should be sealed to prevent rainwater infiltration.

2. Functional Configuration and User-Friendly Details The standard size is usually 1100*1100mm in width and length and 2000mm in height. The interior space is compact but meets basic usage requirements. It comes standard with plastic windows that provide both ventilation and privacy protection; metal locks offer basic security protection, and the color-coated steel trim prevents sharp edges from being exposed, reducing usage risks. According to needs, a shower function can be added, and water leakage is prevented through waterproof sealing design (such as silicone sealing strips) to form a simple shower room. The floor usually does not come with a base and needs to be placed on a flat and hard surface (such as concrete or stone slabs) to ensure stability. If mobility is required, a detachable base can be designed or casters can be added.

3. Dry-Wet Separation Design

• Integrated Design: Some mobile bathroom units adopt a dry-wet separation layout, with a width of 2 meters and a length of 3 meters. The overall appearance is pure white, and an aluminum alloy glass single door is installed. The sink and makeup mirror are placed in the external dry area to prevent water vapor from corroding the equipment.
• Waste Separation Design: Wastewater and solid waste are separated through a drainage trough and a waste collection bucket, reducing the difficulty of cleaning. The drainage trough needs to be designed with a slope (usually ≥ 2%) to ensure smooth drainage of wastewater, and the waste collection bucket needs to be sealed and replaced regularly to avoid odor accumulation. If a septic tank design is adopted, a maintenance port needs to be reserved and its tightness ensured.

4. Low-Cost DIY Design Example A movable toilet can be constructed using buckets and wooden boards: Use wooden boards with casters as the base, fix the cut buckets on the base, cut the buckets to create entrances and exits, and use aluminum-plastic panels to extend and heighten the walls. Install bucket lids as seats or storage spaces, process wooden doors from the wood and install hinges. After constructing the main frame, connect the drainage pipes and install floor drains. Place a green bucket on the top bucket lid and install water pipe connectors. Use PVC pipes to splice and make a showerhead, install a toilet (such as a portable toilet), and apply sealing glue to prevent leakage. This design is low-cost but requires regular maintenance of the drainage system and tightness.
