Rural Household Mobile Dry Toilet

A rural household mobile dry toilet is a movable and flexible sanitation facility, typically made of steel or plastic. It is equipped with a squat toilet and a flush tank, and some models even integrate shower functions. The price ranges from 400 to 5000 yuan, depending on the configuration and specifications.

I. Basic Structure and Functions

The core structure of a mobile dry toilet includes a toilet house, a toilet fixture, a fecal storage tank, and auxiliary facilities. The main body of the toilet house is mostly made of steel or high-strength plastic to ensure structural stability and ease of transportation. The toilet fixture is usually a model specifically designed for dry toilets, with an ergonomic design to reduce fecal residue. The fecal storage tank is used to collect feces, and some models adopt a dual-pit alternating or urine-feces separation design, achieving fecal harmless treatment through separated fermentation tanks. In addition, some high-end models integrate a flush tank and simple shower equipment to meet basic cleaning needs.

II. Price and Specification Differences

Prices are significantly affected by materials, size, and functions. The price of a basic model (e.g., single toilet stall, no additional functions) is approximately 400-800 yuan; a mid-range model (e.g., double toilet stalls, with a flush tank) costs 1000-3000 yuan; and a high-end model (e.g., with integrated shower functions and customized design) can cost over 5000 yuan. For example, the courtyard household mobile dry toilet provided by Henan Qingzhigu Environmental Protection Technology Co., Ltd. has dimensions of 220cm×560cm×280cm, weighs 8000kg, supports customized processing, and starts at 800 yuan per square meter. It is suitable for outdoor scenic spots or public communities.

III. Technical Standards and Specifications

According to the Technical Requirements for the Construction of Rural Household Sanitary Dry Toilets (NY/T 4702—2025) issued by the Ministry of Agriculture and Rural Affairs in 2025, mobile dry toilets must meet the following standards:

• Space requirements: The net area of a single-stall toilet house should be no less than 1.2 square meters, and that of a double-stall toilet house should be no less than 2.0 square meters to ensure user comfort.
• Fecal storage tank capacity: For dual-pit alternating models, the volume of each fermentation tank should be no less than 0.6 cubic meters; for urine-feces separation models, the volume of each single tank should be no less than 0.8 cubic meters to meet fecal fermentation needs.
• Ventilation and exhaust: Exhaust pipes and passive vents must be installed to prevent odor accumulation.
• Harmless treatment: Feces must be treated to harmless standards through fermentation, decomposition, and other processes to avoid environmental pollution.

IV. Applicable Scenarios and Advantages

Mobile dry toilets are suitable for rural courtyards, temporary construction sites, outdoor scenic spots, and other scenarios, especially in areas lacking sewer systems. Their advantages include mobility (easy to rearrange), low-cost maintenance (no need to connect to municipal sewer networks), environmental friendliness (fecal resource utilization), and flexibility (support for customized design).
