San Antonio Restroom Trailer Rental
Restroom trailers are the premium alternative to standard porta potties for events in San Antonio where guest experience matters. Climate-controlled, with running water, flushing toilets, vanity lighting, and full-length mirrors, restroom trailers look and feel like permanent restrooms — on wheels, positioned wherever your event takes place. They're the standard choice for weddings, corporate events, upscale fundraisers, and any event where standard units would feel jarring.
Restroom trailer rental in San Antonio costs $800–$1,500 for a 2-stall unit for a weekend event and $1,200–$2,500+ for 4-stall units. Larger 6-stall and 8-stall trailers for events over 300 guests run $2,000–$4,000. 9 of 9 verified providers in San Antonio carry restroom trailers — fleet size is limited, so book 4–6 weeks in advance for peak season events. Service covers the San Antonio metro including Austin, surrounding areas, Round Rock.
Restroom trailers require a level surface for setup, an external water hookup (garden hose connection), and in most cases external power (30-amp shore power connection or generator). Confirm these requirements with your San Antonio provider before signing — some trailers are fully self-contained with built-in tanks and generators, while others require external utilities. Trailers are typically delivered and positioned by the provider a day before the event.
