Case Study: Customized 3.5m Mobile Toilet Trailer with Shower Transforms Event Hygiene

Client Requirements

1. Dual-Purpose Functionality: Combine restroom and shower facilities in a single compact unit.
2. Energy Efficiency: Operate on 110V/60Hz power to align with North American standards.
3. Brand Visibility: Incorporate a customizable logo and premium aesthetics.
4. Sustainability: Minimize water waste and ensure easy waste disposal.
5. Mobility: Meet Canadian towing regulations with detachable axles for transport.

Solution Design & Implementation

1. Structural Innovation

• Material Choice: The trailer’s exterior was crafted from FRP (fiberglass-reinforced plastic) , known for its durability, weather resistance, and low maintenance. This material ensured the unit could withstand harsh outdoor conditions while maintaining a sleek, professional appearance.
• Space Optimization: The 3.5m x 2.1m x 2.55m layout featured two independent restroom units, each equipped with a flush toilet, shower stall, LED mirror, and sink. A dedicated equipment room housed the 110V dual-temperature AC and water systems.
• Mobility: A dual-axle chassis with electromagnetic brakes and aluminum alloy wheels ensured safe towing. The axles and tires were detached during shipping to comply with Canadian transport regulations .

2. Electrical & Utility Systems

• Power Supply: The 110V/60Hz system included US-standard outlets in each restroom for charging devices. A dedicated circuit powered the AC unit, which distributed air via ducts to maintain comfort in extreme temperatures.
• Water Management: A plastic freshwater tank (with level indicator) and wastewater tank (with sewage meter) supported self-sufficiency. A high-efficiency water pump provided consistent pressure for showers and sinks.
• Hot Water Readiness: The trailer was pre-plumbed for a tankless propane water heater , with a designated space in the equipment room. This allowed the client to install the heater post-delivery for added flexibility.

3. Branding & Aesthetics

• Custom Logo Integration: The client’s logo was seamlessly embedded into the exterior FRP panels using UV-resistant vinyl decals , creating a cohesive brand presence.
• Interior Finishes: The restrooms featured stainless steel fixtures and non-porous surfaces for easy cleaning, while LED lighting and modern mirrors enhanced the premium feel.
• Exterior Signage: Illuminated "Occupied" indicators above each door ensured clear user guidance, even in low-light conditions.

4. Compliance & Safety

• Regulatory Adherence: The trailer met Canadian towing standards and included emergency ventilation systems and non-slip flooring for safety.
• Waste Management: The wastewater tank’s epoxy coating prevented corrosion, ensuring longevity and compliance with environmental regulations.
