Container House Bathroom Treatment

The treatment of container house bathrooms requires focused attention on aspects such as waterproofing and moisture resistance, drainage systems, sewage disposal, and ventilation and exhaust. Scientific design can ensure their safety, durability, and environmental friendliness.

Waterproofing and Moisture Resistance Treatment

The bottom of the container is made of steel structure, which is prone to rusting and perforation when exposed to moisture for extended periods. Before renovation, thorough rust removal and application of anti-rust paint are necessary. After laying a 20mm thick cement mortar leveling layer, cover it with waterproofing membranes or coatings. The inner and outer surfaces of the wall and ceiling steel plates should be coated with waterproofing paint, and the joints should be sealed with special sealant to prevent moisture penetration. Doors and windows should be made of materials with good waterproofing properties, and the sealing strips should be intact during installation to prevent rainwater infiltration.

Drainage System Design

The slope of the drainage pipe should be no less than 2%, and PVC pipes with a diameter of more than 50mm should be selected to avoid water accumulation and corrosion of the structure. The drainage outlet should be pre-drilled on the side wall of the container to avoid damaging the structure by cutting later and should be directed to external centralized treatment. An effective floor drain should be installed inside to ensure smooth drainage and prevent water vapor retention. The electrical circuit and pipeline should be designed separately: the electrical circuit should be laid through pipes on the top of the container, while the water supply and drainage pipelines should be routed along the bottom or side walls, maintaining a minimum distance of 30cm to reduce the risk of short circuits.

Sewage Disposal Plan

If conditions permit, direct connection to the municipal sewage pipeline is possible; in the absence of a pipeline network, a clean water tank and a sewage collection tank should be equipped, and regular cleaning should be carried out. Small or temporary toilets can use septic tanks or biodegradable devices. Large or long-term use toilets can be connected to efficient sewage treatment systems or use biological treatment technologies (such as microbial degradation) to purify sewage. Common sewage disposal methods include connection to the urban drainage system, temporary storage in septic tanks, collection in storage tanks + suction pump/gravity drainage, purification by biological treatment systems, and decomposition of sewage by decibel systems (suitable for wild or temporary locations).

Ventilation and Deodorization Design

An exhaust fan or fresh air system should be installed for forced ventilation to maintain air circulation and reduce odors and bacterial growth. At the same time, deodorants or biodegradable technologies can be used to further reduce odors and enhance the user experience. Modular design allows for flexible combination of containers to achieve functional zoning (such as separate areas for men and women, public washbasins, etc.) and预留（此处英文原句缺失对应翻译内容，推测“预留”为“预留通风管道接口”相关，补充翻译为“reserves ventilation duct interfaces”) ventilation duct interfaces for easy installation of equipment at a later stage.

By implementing these measures, container house bathrooms can effectively address issues related to waterproofing, drainage, sewage disposal, and ventilation, while ensuring safety, durability, and environmental friendliness.
