Although we know that some things in life can be replaced, there are still many issues in use, such as with our containers. So how can drainage be addressed for custom containers?  
Since custom containers are sealed, residents can benefit from ventilation windows in hot summer months to circulate indoor air. If the container cannot have windows, installing exhaust fans can solve this issue, allowing air to flow within the room, so people do not feel like they are living in a sealed box. This provides a ventilation experience and creates a comfortable living environment for residents. Installing waterproof floor drains in containers addresses drainage issues for second-hand container homes. For inhabited container floors, installing waterproof floor drains can resolve difficulties when doing laundry or cooking. This installation should be included during the design and renovation of a container for living purposes. Generally, reputable container home companies will inform residents about this issue to ensure convenient drainage.  
For custom drainage issues in inhabited containers, waterproof floor drain pipes can be installed on the container floor. This resolves installation problems arising from indoor water use and should be implemented during construction.  
During this period, various industries are in a high-development stage. During the construction of numerous long-term buildings, structures, roads, bridges, and transportation facilities, and in their future use, a large number of temporary buildings and supporting facilities are needed. Additionally, industries requiring long-term outdoor or open-air work, urgent needs, or disaster relief, as well as high tourist flow during festivals or peak periods, require temporary buildings to meet different needs.
