Indoor Movable Assembled Toilet

An indoor movable assembled toilet is a sanitary facility that can be flexibly assembled and moved according to needs, offering convenience and practicality. Common types include homemade simple versions and commercially available assembled models. The following provides an introduction from three aspects: structure, types, and characteristics.

I. Structural Composition
A movable toilet typically consists of core functional modules and auxiliary structures. The core modules include fecal and sewage storage tanks (or disposal units), sanitary fixtures (such as toilets and squat pans), and water tanks, responsible for treating excreta and providing flushing functions. The auxiliary structures cover walls, roofs, and flooring, providing privacy protection and usable space. The mobility devices (such as universal wheels and towing structures) endow it with mobility. Some high-end models are also equipped with grooming equipment (sinks), shower rooms, and drainage pipes and floor drains to meet diverse needs. For example, in a homemade case, the user uses a wooden board with universal wheels as the base, cuts a bucket to serve as a sewage container, fixes and extends it with wooden strips, installs a lid, and finally connects it to a drainage pipe to achieve a functional closed loop.

II. Type Classification

1. By structural form: Divided into single-unit structures (independent units suitable for small spaces) and composite structures (multi-module combinations that can be expanded into shower rooms, changing rooms, etc.).
2. By mobility method: Includes lifting/handling types (requiring mechanical assistance for movement) and powered/towing types (tractable or self-powered).
3. By sewage treatment method: Water-flush types (requiring a water connection, high cleanliness), waterless suction types (regular fecal transportation), recirculating water-flush types (water recycling, water-saving), and dry-pack types (using biodegradable bags, no water required). Commercially available assembled models often support customization, allowing users to choose types based on the scenario, such as dry-pack types for temporary household use and recirculating water-flush types for construction sites or exhibitions.

III. Core Characteristics

1. Mobility: Position adjustments are achieved through wheels, towing structures, or mechanical lifting, adapting to scenarios such as renovations, exhibitions, and temporary events.
2. Easy assembly: Modular design simplifies the installation process, allowing two people to complete assembly in half an hour, reducing labor and time costs.
3. Economical transportation: When disassembled, the small volume saves on logistics costs, making it especially suitable for remote areas or frequent relocation scenarios.
4. Flexible functionality: Supports the addition of modules such as toilets, showers, and sinks as needed, and can even integrate air conditioning and ventilation systems to enhance comfort.

It should be noted that homemade movable toilets need to ensure sealing (such as applying sealant to prevent leakage) and stability (such as fixing wooden strips to avoid wobbling), while commercially available products need to focus on material durability (such as moisture-resistant walls) and environmental certifications (such as sewage treatment compliance).
