It measures approximately 3,000 × 1,800 × 2,650 mm and is supplied as a stall portable shower unit for buyers who need both washing and toilet functions in one towable body.

The manufacturer operates a 4,500 m² production facility established in 2015 and exports to more than 50 countries. Production follows ISO 9001 quality management, and applicable configurations carry CE, DOT, EPR and COC documentation. Third-party inspections are conducted by SGS and Intertek.

Technical Parameters

The dimensions and weight are reference values. The final transport weight changes after adding water heaters, electrical components, air-conditioning equipment, extra sanitary fixtures and branding materials.

Recommended Operating Procedure

The TN-S30 is designed for locations that need basic shower and restroom functions in one movable unit. It is used at small construction sites, outdoor events, campsites, sports activities, film locations and temporary accommodation areas.

Before Use

1. Position the trailer on stable and reasonably level ground.

2. Extend the support legs and check that the body is stable.

3. Fill the 400 L fresh-water tank with suitable water.

4. Inspect the pump, hoses, faucets and visible pipe connections.

5. Test the shower head and adjust the water temperature.

6. Check the toilet flushing system and sink drainage.

7. Confirm that the 800 L wastewater outlet is closed.

8. Test lighting, ventilation and optional air-conditioning equipment.

During Operation

The operator monitors water consumption and wastewater levels according to actual usage. Water demand varies with shower duration, toilet flushing, hand washing and cleaning frequency. For a busy event, the tank service interval is shorter than for a small worksite.

The shower room is cleaned regularly, especially around the floor, drain, shower fittings and door handle. Standing water is removed promptly to reduce slipping risk. The toilet, sink and faucet are checked for leakage during each cleaning round.

Interior Configuration and User Experience

The shower area is fitted with an overhead shower head, handheld shower head and adjustable shower rod. A hot-and-cold water system is selected when the project requires temperature adjustment. The exact water-heating method, power supply and installation requirements are confirmed before production.

The toilet section includes a foot-flush toilet, hand-washing sink, push-button faucet, mirror with lighting and selected sanitary accessories. A men’s sensor urinal is added if the internal layout allows sufficient service and cleaning access.

The interior is customized with:

● Water heater

● Clean-water tank

● Wastewater tank

● Exhaust fan

● Additional lighting

● Air-conditioning system

● Music player system

● Storage hooks

● Interior color and finish

A compact portable restroom shower trailer is useful when the buyer wants to avoid transporting separate shower and toilet units. The available space, expected number of users and service capacity are evaluated before ordering.

Material and Safety Details

The body uses 40 mm fiberglass sandwich panels. The panel structure provides an enclosed wall system with an insulation layer, while the interior surface is maintained with cleaning products suitable for fiberglass and sanitary areas.

The shower floor uses non-slip material and has a planned drainage route. Door locks, hooks and internal fittings are checked during routine maintenance. If the unit is used in a cold region, exposed water pipes and tanks require insulation, draining or other winter protection.

The trailer uses one torsion axle with brakes and two 195/70 R15 tires. Before relocation, inspect the hitch, safety chains, brake connection, road lights, tire condition, wheel fasteners and support legs. The towing vehicle is selected according to the fully loaded trailer weight rather than the empty reference weight.
