Modular Toilets

Modular toilet modules are prefabricated lavatories engineered for train and metro interiors. Constructed from lightweight aluminum honeycomb composite panels and FRP skins, these units maximize strength while minimizing weight. They are fully compliant with accessibility standards (e.g. PRM-TSI) and can be customized for new-build or refurbished coaches. Fixtures typically include a vacuum or flush toilet, sink, grab rails and baby-changing surfaces in a compact footprint. Surfaces are finished with high-pressure laminates (HPL) or antibacterial gelcoats for a hygienic, durable interior.

Key Features

Lightweight Composite Construction: Aluminum honeycomb core panels provide high strength-to-weight performance.
Accessible Design: Fully compliant with PRM-TSI (Persons with Reduced Mobility) requirements.
Integrated Fixtures: Includes built-in sinks, vacuum toilets, handrails, coat hooks and baby-care stations in one module.
Anti-Bacterial Finish: High-pressure laminate or silver-ion coatings resist bacteria, staining and wear.
Modular Assembly: Plug-and-play panel sections for rapid installation in new or refurbished trains.

Benefits

Passenger Convenience: Provides modern, accessible restrooms onboard, improving comfort and meeting disability-access regulations.
Fast Installation: Prefabricated units significantly reduce assembly time and on-site labor.
Low Maintenance: Smooth, sealed surfaces are easy to clean and resist odor and wear.
Energy Savings: Lightweight design helps lower fuel/power usage (lighter trains require less energy).
Regulatory Compliance: Meets international rail hygiene and fire-safety standards.

Applications

Passenger Trains and Metros: Installed in coaches, EMUs and subway cars as standard or wheelchair-accessible toilets.
New Builds and Refurbishments: Suitable for integration in brand-new fleets or retrofitting older cars.
Multiple Vehicle Types: Used in intercity, regional, high-speed and commuter rolling stock.

Technical Specifications

Materials: Aluminum honeycomb core panels with FRP/GFRP skins, HPL exterior laminates.
Dimensions: Customizable to train coach layouts (typical modules ~1.5×1.0×2.1 m).
Weight: Thin FRP walls (~5–10 mm) weigh under 10 kg/m², reducing overall car mass.
Standards: Fire-retardant materials meeting TB/T 3138, 3139 (China) and DIN 5510-2 (Europe) fire/smoke regulations.
Toilet System: Vacuum or gravity-flush options; complies with TB/T 3338 vacuum toilet specs.

Unique Selling Points (USPs)

Fully Certified: Built to PRM-TSI and international fire-safety standards.
Custom Engineered: Panels and fixtures tailored to any train profile or brand scheme.
Durable Hygiene: Special coatings (e.g. antimicrobial HPL) ensure long-term cleanliness.
Lightweight Design: Aluminum honeycomb structure saves weight without sacrificing rigidity.
