Portable Toilet: A Practical Buyer's Guide

Portable toilets are movable sanitation facilities designed to supplement the shortage of fixed public toilets, suitable for stations, construction sites, tourist attractions, and other scenarios.

I. Structure and Classification

The core components of portable toilets include fecal sewage storage tanks, sanitary ware, walls, water tanks, and mobile devices. Based on structural form, they can be divided into monolithic structures (independent units) and composite structures (multi-unit combinations). Mobile methods include lifting/handling types (requiring mechanical assistance) and powered/trailer types (capable of self-movement or trailer transportation). Sewage treatment methods cover flush types (requiring a water source), waterless flush suction types (vacuum sewage suction), recirculating flush types (water-saving purification), and dry packing types (waterless, fecal packing treatment).

II. Materials and Evolution

Early portable toilets were mostly made of wood, which easily absorbed odors and had poor durability. Modern products commonly use environmentally friendly materials such as fiberglass or polyethylene, which are odor-resistant, corrosion-resistant, easy to clean, and significantly improve service life.

III. Special Designs of Portable Toilets

1. Folding Portable Types: For example, the leaf-shaped portable toilet designed by German designer Eva Tint. It folds to just 12×28 cm and can fit into a handbag. It contains a super-absorbent agent inside that converts liquid into gel to prevent leakage, comes with cleaning wipes, and can be disposed of as ordinary garbage after use.
2. Expanded Usage Scenarios: Initially targeting female users to address long queues in public restrooms, it has since expanded to scenarios such as car travel and outdoor gatherings, and is now unisex.

IV. Procurement Advice

1. Supplier Selection: Prioritize manufacturers with quality certifications, such as LEBON Integrated Housing Company in Linyi, Shandong. Their products are exported to over 30 countries with an annual export volume exceeding 13,500 units, support FOB Qingdao Port trade terms, and provide 24/7 technical support.
2. Type Matching: Choose structures and sewage treatment methods based on usage scenarios. For example, for temporary event needs, dry packing types or waterless flush suction types may be suitable, while for long-term construction site use, recirculating flush types or flush types are recommended.
3. Cost and Installation: Pay attention to the ease of installation of modular design products and long-term maintenance costs to avoid high expenses later.

V. Application Case

In 2023, portable toilets were put into use in the Lanzhou Yellow River Scenic Area, demonstrating their practicality in high-traffic public scenarios and effectively alleviating the restroom problem for tourists.
