Capacity is the first surprise. Two restrooms off a barn handle a rehearsal dinner. They do not handle 180 guests across a five-hour reception, and they do not handle a catering crew that needs somewhere to wash. Guest counts also climb after the venue is booked, so the restroom count usually gets checked against an early number instead of the final one.
Booking late is what turns that into a problem. Hill Country venues get claimed 12 to 18 months ahead for peak spring and fall Saturdays, and the vendors servicing those venues work off the same calendar. Restrooms tend to be the last line on the vendor list, which puts the call weeks out from a date where the inventory went months ago.
The hardest version is a site with nothing to connect to. A large share of ranch and river venues have no water line and no sewer connection at the ceremony site, and some have no power. Most rental companies cannot handle that, which leaves you with a row of units and a caterer with nowhere to wash. We carry water tanks and holding tanks alongside the units, so the site works for the whole event.
| Market | When it peaks | Events we cover | What these venues usually lack | Service area pages |
| San Antonio and Bexar County | April festival window, February rodeo and stock show season | Parish festivals, school fundraisers, quinceañeras, corporate campus events, food truck rallies, charity runs and cycling events | Capacity. Grounds and venues are sized for an ordinary weekend | San Antonio |
| Austin and Travis County | Spring and fall | Music and food festivals on park land, endurance and race events, ranch and vineyard weddings, corporate campus gatherings | ADA compliance on public ground, plus separate clusters along a race course | Austin |
| The Hill Country | March to May, September to November | Weddings at 100 to 300 guests, town festivals and market days, county fairs and rodeos, river season events | Water and sewer at the ceremony site, sometimes power as well | Boerne, Kerrville, New Braunfels, San Marcos |
| South Texas towns | Spring and fall fair season | County fairs, agricultural festivals, rodeos, ropings, jackpot barrel races, ranch weddings, family reunions | Permanent facilities anywhere near the crowd | Seguin, Floresville, Poteet, Gonzales |
April is the heaviest sanitation window of the year here. A stretch of overlapping public celebrations runs for the better part of two weeks and spills into Boerne, Schertz, and Alamo Heights, and inventory across this market is committed that week. An April date needs a booking conversation months earlier than a June one.
The rest of the calendar runs on private property. Quinceañeras, milestone birthdays, and large family gatherings happen at homes and ranch properties around Bexar County, where the house has one or two bathrooms and the party has ninety people. Parish festivals, school fundraisers, and corporate events repeat on a known date with a known headcount, which makes them simple to size and easy to book early. San Antonio service runs out of our yard on the southeast side.
This is where the water and holding tank capability earns its place. Guest counts commonly land between 100 and 300, and ranch and river venues here frequently have a handful of permanent restrooms or none at all. A fair number have no water or power at the ceremony site itself, which changes the order from a row of units to a full setup.
Town festivals and county rodeos fill fairgrounds and squares built for an ordinary Saturday, and river season on the Guadalupe and the Comal runs from May through Labor Day. Those dates compete for the same weekend inventory as the weddings, which is why a peak Saturday needs an early call.
The unit most of your guests will use, delivered clean and stocked. Placement decides whether the line forms across your ceremony aisle or your bar service, so we plan it with you.
Built with the 60-inch interior turning space a wheelchair user needs, and marked with the International Symbol of Accessibility. At an event open to the public, the law treats these as a requirement.
Interior finish, lighting, and running water, for weddings and corporate events where the restroom is part of what guests remember about the evening.
Standalone stations for catering crews, food service, and any event where people eat standing up with their hands.
Water delivered to a site that has none, supplying the units, the caterer, and the crew for the length of the event.
Above-ground waste storage, drop off only, with no plumbing involved. This is the piece that lets a venue with no sewer connection host a full weekend.
Running a job site instead of an event? Ongoing crew service, weekly servicing, and jobsite unit counts are covered on our porta potty rental page.
Start with guest count and duration. One unit per 50 guests for a four-hour event is the working baseline, and it holds up well for a simple afternoon.
| Guests, four-hour event | Standard Units | Standard Units |
| Up to 50 | 1 | 1 |
| 100 | 2 | 1 |
| 150 | 3 | 1 |
| 200 | 4 | 1 |
| 300 | 6 | 1 |
| 500 | 10 | 1 |
Accessible units come out of that total, not on top of it. The 2010 ADA Standards require access to at least 5% of the portable units in each cluster at a temporary event, with a minimum of one, so a cluster stays at one accessible unit until it passes 20 units and then needs a second.
Four things push the count above the baseline. Length is the most common. An eight-hour reception needs a bigger order than a four-hour one. Alcohol service raises usage noticeably, and a bar running all evening will do it more than a champagne toast. Multiple days change the servicing plan as much as the unit count. And a split site, where the ceremony sits on a hilltop and the reception is down at the barn, is two clusters, which usually means an accessible unit at each.
Standard units or a trailer is a separate decision from how many. Trailers do more per unit and read better at a formal event, though they need a level spot, vehicle access to reach it, and a power source or a generator. On a rough ranch site, a well-placed row of standard units with a handwashing station often serves guests better than a trailer parked wherever the ground allowed.
Call 210-372-8666 and we will size the order against your venue, not a calculator.
Add anything unusual about the site: no water, no power, a long gravel drive, a ceremony spot the truck cannot reach.
Where the clusters go, how guests reach them, and where the accessible units sit so they are not the far corner of the field.
Units, tanks, and stations are set and checked before your setup crew needs the site.
Multi-day dates and high-traffic events get servicing scheduled into the rental, planned around the event schedule so it does not happen during your ceremony.
We clear the site after teardown.
“Booked a big ol' dumpster online, easy as pie. Arrived on demo day, clean and strong enough for all the bricks and shingles. Crew filled it fast, no overflowing mess. One call later, South Texas Dumpsters hauled it away next day, leaving my driveway spotless. No hidden fees, just fast, professional service. Saved me tons of trips to the dump and backaches."

“Service has been great! It's refreshing to work with such an organized and professional group! Even when we give them last minute notice, they get us taken care of! Thanks for the flexibility and continued good communication!”

“I would recommend. Great customer service, easy to get and on time delivery.”

Fresh water tanks, non-potable water tanks, and large quantity holding tanks come from the same provider as the units. A ranch venue with no water and no sewer gets a setup that works for the whole event, including the caterer.
Our confirmed event work includes the Austin rodeo and events in Montgomery County. At that size, guessing at unit counts stops working.
You reach the people who dispatch the trucks. There is no call center between you and the person who knows whether a driver can get up your access road.
Festivals, fairs, and large private events leave a volume of waste that household bins cannot take, and we handle roll-off containers alongside the sanitation order. A 20-yard roll-off placed near the vendor area handles most single-day events, and it goes on the same quote as your restrooms.
Start at one unit per 50 guests for a four-hour event. Add units for anything longer, for a bar running all evening, and for a second cluster if the ceremony and reception are far apart. Every event has something the formula misses, so call 210-372-8666 with your guest count and your venue and we will size it with you.
Book your restrooms as soon as your venue is booked. Peak Saturdays in March through May and September through November are the first dates to go across every vendor category in this market, and sanitation inventory is finite on those weekends. If your venue is booked, book your restrooms. If you are still deciding between dates, call and we will tell you what our availability looks like on each one.
If your event is open to the public, yes. The 2010 ADA Standards require access to at least 5% of the portable units in each cluster, with at least one accessible unit, and where a single unit is provided that unit has to be accessible. Accessible units also need to sit with the main cluster on a route guests can travel, since a unit at the far end of an uneven field does not meet the intent. Private events are treated differently, though we would still recommend one if any guest may need it.
Yes, and it is a large share of what we do in the Hill Country. Fresh water and non-potable water tanks supply the units and the catering crew, and large quantity holding tanks handle waste above ground with no plumbing connection. Tell us what the site does have, including access road width and how close a truck can get to the ceremony spot, and we will plan the setup around it.
A standard portable restroom is a self-contained single unit that goes almost anywhere, including soft ground and tight spots. A deluxe restroom trailer has interior finish, lighting, and running water, and it needs a level spot, vehicle access, and power. Trailers suit formal weddings and corporate events. Standard units suit rough terrain, large crowds, and anywhere a truck cannot comfortably reach.
Multi-day events and high-traffic single-day events include servicing across the run of the event. The schedule is set as part of your quote, built around your event program so servicing does not land in the middle of a ceremony or a headline set. Call with your run of show and we will build the cadence around it.
Your quote comes down to how many units and which kind, how long the event runs, how much servicing it needs, and how far the venue sits from our yard. A site needing water tanks and holding tanks prices differently from a park with hookups. Call 210-372-8666 with those details and you will get a number built for your event, not a range that moves once we see the site.
Yes. Roll-off containers for post-event cleanup go on the same order as your restrooms, which keeps teardown with one provider and one point of contact. Tell us the event size and whether vendors are breaking down on site, and we will recommend a size alongside your sanitation quote.
Give us your date, your venue, and your guest count, and we will come back with a unit plan and a quote built for your site. Call 210-372-8666 to talk it through with someone who knows these venues, or send the details through our contact form and we will follow up. Peak spring and fall Saturdays go early across San Antonio, Austin, and the Hill Country. The sooner we have your date, the more options you have.
