Dimensions of Mobile Prefab Toilets

The common dimension designs for mobile prefab toilets need to be comprehensively determined based on usage scenarios, functional requirements, and compliance standards, as detailed below:

I. Basic Dimension Standards

1. Single-stall Dimensions

   • Men's Urinal Area: It is recommended that the width be ≥0.8 meters and the depth be ≥1.2 meters to meet basic usage needs.
   • Squat/Sit-down Stall Area: The net dimensions of a single stall are recommended to be 1.2 meters × 1.5 meters (including partition thickness), with partition heights needing to be ≥1.8 meters to ensure privacy.
   • Women's Single Stall: Due to the need to accommodate facilities such as waste paper baskets, it is recommended that the dimensions be 1.5 meters × 1.5 meters for more spacious accommodation.
   • Mobile Bathroom Units: There are two mainstream specifications:
     • Basic Type (1200mm × 1200mm): Meets the needs of single-person usage and is suitable for compact scenarios.
     • Comfort Type (1500mm × 1500mm): Can be equipped with more functional equipment (such as sinks and storage cabinets).

2. Overall Layout

   • Width: The total width of men's and women's toilets is usually 3-4 meters (double-row layout) or 2-2.5 meters (single-row layout), and needs to be adjusted according to the flow of people.
   • Length: Each additional squat stall requires an extension of 1.5-2 meters. For example, the length of a toilet with three squat stalls is approximately 4.5-6 meters.

II. Scenario Adaptation Solutions

1. Temporary Toilets on Construction Sites: Adopt a compact design, with single-stall dimensions often being 2.4 meters × 1.2 meters, paired with a modular structure for rapid deployment.
2. Toilets in Scenic Spots/Parks: Need to consider barrier-free access, with single stalls recommended to be expanded to 1.8 meters × 2 meters, and a 1.5-meter-wide passage reserved.
3. Special Needs: For usage scenarios by disabled individuals, the unit needs to be enlarged to 1800mm × 1800mm, and equipped with barrier-free handrails and emergency call devices.

III. Impact of Materials and Craftsmanship

1. Color Steel Plate Structure: With a thickness of 40-80mm, it is necessary to reserve 5cm of space for the insulation layer to avoid freezing in winter or overheating in summer.
2. Composite Materials: Due to the decorative layer requiring an additional 2-3cm of outer frame dimensions, space needs to be reserved in advance during design.

IV. Compliance Requirements

Must comply with the "Urban Public Toilet Design Standard" (CJJ14-2016):

• Passage width ≥1.3 meters to ensure wheelchair access.
• Barrier-free facility single-stall dimensions ≥1.6 meters × 1.8 meters, and equipped with handrails and emergency call devices.

V. Recommended Configuration Cases

1. Economical Solution: Such as the connected public toilets (1.1 × 1.1 × 2.4-meter single stalls) from Zhengzhou Jiuyuan Sanitation, suitable for short-term events or temporary use.
2. High-end Custom Solution: Such as the container toilets from Guangdong Bianjie Environmental Protection, which can be expanded to an overall space of 3 × 6 meters, integrating facilities such as sinks and air conditioners.
