3-Door Mobile Toilet Trailer

The 3-door mobile toilet trailer is the size that fits most jobs: three independent cubicles with their own doors and fold-down steps, on a single towable unit that one vehicle can deliver and position. It is the standard choice for weddings of 100 to 250 guests, school sports days, church gatherings, weekend markets, film sets and construction sites with 30 to 60 workers.

Because every cubicle has its own door, the trailer serves three people at once and never requires men and women to share a queue. The interiors are lit by LED on individual switches, fitted with flush toilets, ventilated through roof vents and finished in wipe-clean materials that stand up to daily site use as well as a white-linen event.

Water and waste are managed from an external service compartment: a fresh-water tank feeds each toilet through a 12 V demand pump, and a large waste tank holds the volume from a full weekend of events. Emptying is done from outside the cubicles through a service hatch, and the tanks are sized so that servicing can be scheduled between events rather than during one.

The body is an insulated panelled shell on a welded ladder-frame chassis finished in a light neutral tone, with a sealed non-slip floor and lockable doors. Running gear is a braked axle on leaf springs with 14 inch light-truck tyres, which keeps the trailer stable when the waste tank is full - the condition in which a poorly balanced toilet trailer becomes unpleasant to tow.

If you are buying for a hire fleet, this is the model with the best balance of capacity, weight and serviceability: big enough to earn its keep on every booking, small enough to tow and clean with one person.
