Mobile Toilets for Old Buildings

Mobile toilets for old buildings can solve sanitation problems through two methods: installing facilities indoors or renting municipal mobile toilets.

I. Installing Mobile Toilet Facilities Indoors
For the renovation of interior spaces in old buildings, it is necessary to combine the building structure with residents' needs and create space for facility installation by relocating unused items. For example, the lane houses at 1543 Sichuan North Road in Hongkou District were built in the 1920s and originally had no independent bathrooms, with residents long relying on portable chamber pots. During a sporadic urban renewal project, by clearing out unused items such as large wardrobes in the building, space was freed up to install electric toilets, along with the renovation of sewage discharge pipes, ultimately solving the sanitation problem. Such renovations require attention to three points:

1. Space Assessment: Prioritize the use of non-load-bearing areas such as stair corners and unused storage rooms to avoid compromising the building's structural safety;
2. Facility Selection: Choose compact, water-saving electric toilets suitable for the low water pressure environment of old buildings, equipped with odor-proof floor drains and sealed doors;
3. Pipe Renovation: Plan the sewage discharge path, which can be connected to the original septic tank or include the installation of small-scale sewage treatment equipment to ensure compliance with environmental standards.

II. Municipal Mobile Toilet Rental Solutions
During urban renewal construction periods or in public areas around old buildings, renting municipal mobile toilets can provide flexible temporary solutions. Their core advantages include:

1. Rapid Deployment: Modular design allows installation within 24 hours, saving 60% of the construction time compared to traditional toilets, and adapting to the tight schedules of old building renovations;
2. Strong Environmental Adaptability: Made of moisture-proof and corrosion-resistant materials, equipped with canopies and drainage systems, they can withstand rainy and humid climates, with a service life of 8-10 years;
3. Smart Management: Some models integrate features such as sensor flushing, air purification, and real-time monitoring, reducing manual maintenance costs;
4. Flexible Location: Their positions can be adjusted according to construction progress or residents' needs, avoiding the occupation of public space by fixed toilets.

Application Scenario Recommendations: If the renovation of old buildings involves overall structural adjustments, municipal mobile toilets can be set up in open spaces outside the building or on nearby streets during construction; if the renovation is limited to indoors, the installation of electric toilets should be prioritized. Both methods can be implemented through government public welfare projects or corporate rental services, requiring advance planning of sewage discharge pipes and electrical connections to ensure compliance with regulations.
