High-Quality Portable Outdoor Restrooms Supplier & Factory

Every restroom unit leaving our Suzhou manufacturing facility is tailored to the exact destination regulatory framework. For North America, we configure plumbing to meet Uniform Plumbing Code (UPC/cUPC) and electrical configurations to UL/CSA standards with 110V/60Hz GFCI circuit breakers. For Europe and the UK, systems are configured to CE/BS EN standards with 220–240V/50Hz circuits and standard 110mm push-fit waste pipes. For Australia and New Zealand, we supply WaterMark-certified sanitary fixtures and AS/NZS 3000 compliant consumer units. All piping, valves, wire gauges, and drainage slopes are clearly documented in 3D CAD shop drawings before manufacturing begins.

With our 28,000 m² factory footprint and automated CNC production lines, standard single or dual-unit prototype orders are fabricated and pre-assembled within 10 to 14 days. For large-scale batch procurement—such as 20 to 50 modular container restrooms for infrastructure sites or resort parks—our factory sustains a throughput of 5,000+ modular units per month, delivering multi-container orders in 20 to 28 days. Pre-shipment hydro-testing and packaging are integrated directly into this production timeline.

For alpine, Nordic, or high-latitude installations, we upgrade the building envelope to 100mm high-density continuous Polyisocyanurate (PIR) or Rockwool insulation cores, combined with broken-bridge double or triple-glazed argon-filled windows. Crucially, all internal freshwater supply PEX lines are fitted with self-regulating thermostatically controlled electric heat-trace cables and enclosed within internal insulated pipe chases. High-efficiency inverter heat pumps or explosion-proof electric baseboard heaters maintain the interior room temperature well above freezing even in sub-zero ambient conditions.

Yes. We offer fully self-contained off-grid modular packages. These configurations include an integrated under-floor or external skid-mounted high-density polyethylene (HDPE) waste holding tank (ranging from 1,000 to 5,000 liters) equipped with electronic high-level ultrasonic sensors and external quick-connect cam-lock vacuum extraction valves. Alternatively, for permanent remote eco-resorts, we integrate multi-stage biological aerobic digestors or micro-MBR (membrane bioreactor) wastewater treatment modules that convert blackwater into Class-A treated graywater suitable for subsurface irrigation.

All units are prepped with heavy-duty export weatherproofing. Exterior painted surfaces receive an epoxy zinc-rich primer and polyurethane topcoat tested for 1,000+ hours of continuous salt-spray resistance. Internal sanitary fixtures (ceramic toilets, mirrors, vanity glass) are stabilized with custom rigid-foam blocking and anti-vibration strapping. Exterior openings and glass facades are clad in heavy corrugated protective wrap and edge protectors. Units loaded as standard SOC (Shipper Owned Containers) or inside 40HC shipping containers are securely chocked and welded to ISO corner castings to prevent shifting during transit.
