What Sizes of Restroom Trailers Are Available?
Great Falls Porta Pros carries 2 stall restroom trailers for small gatherings, 4 stall restroom trailers for mid-size crowds, and 8 stall restroom trailers for festivals or multi-day builds where a bank of standard portable toilets just will not cut it. A 2 stall unit fits a backyard wedding or a small crew. An 8 stall unit handles a county fair crowd or a marathon finish line. If you also need people washing off dust or paint, a shower trailer rental pairs well with any of these, and some clients combine one with a luxury restroom trailer for a full comfort station. For events under 50 guests, a handful of deluxe flushable porta potties can do the job at a lower cost than a trailer. Not sure which tier fits your headcount? The how many porta potties do I need guide walks through the math, and our portable restroom rental page covers every option side by side.
Restroom Trailer Rental Cost
Pricing depends on trailer size, rental length and whether it is an event or a longer job. Below are the bands we see across the industry, drawn from our own pricing data.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | 175 | 800 | 2,500 |
| Week | 150 | 1,397 | 1,650 |
| Weekend | 900 | 2,000 | 3,000 |
| Event (multi-day) | 2,499 | 3,500 | 3,899 |
A single-day rental swings widely because it covers everything from a compact 2 stall unit to a full luxury trailer with attendants. For a deeper breakdown by stall count and trip charges, see restroom trailer rental cost. If a trailer is more than your event needs, compare it against a standard unit on our porta potty rental cost and porta potty rental per day pages.
Do I Need a Restroom Trailer or a Standard Porta Potty?
A trailer makes sense once you are hosting guests who expect a flushing toilet, running water and a mirror, not just workers on a job site. Weddings, corporate events and film shoots lean toward trailers; construction crews usually stick with standard porta potty rental or an ADA accessible porta potty to meet OSHA 1926.51(c) toilet ratios. That standard requires 1 toilet facility for 20 workers or fewer, scaling up from there. If your event mixes public guests and paid crew, you may want both: a trailer near the guest area and a cluster of porta john rentals near the work zone. Our construction site services page details what job sites typically need, and event restroom rental covers the guest side.
Where Do You Deliver Restroom Trailers Near Great Falls?
Great Falls Porta Pros delivers restroom trailers throughout Great Falls and into nearby communities, including Black Eagle 3.9 miles northeast, Gibson Flats 5.4 miles southeast, Malmstrom AFB 5.9 miles east, Big Stone Colony 11.4 miles southeast and Sand Coulee 13.5 miles southeast. Delivery needs about 60 feet of straight clearance behind the trailer, so tight lots or narrow alleys in downtown Great Falls should be flagged when you book. Check our service areas page for a full list, or look up your specific town: Black Eagle, Gibson Flats, Malmstrom AFB, Big Stone Colony or Sand Coulee. Our main porta potty rental Great Falls page has more on service radius and lead time.
What Is Inside a Luxury Restroom Trailer?
A luxury restroom trailer step-up from the standard unit gives you real flush toilets, sinks with running water, climate control and finished interior walls instead of a single molded stall. Accessible clearance still matters even in a trailer: ADA Standards 403.5.1 calls for a 36 inch clear route, 404.2.3 sets a 32 inch minimum door opening, and 304.3.1 requires a 60 inch turning circle where a unit is marked accessible. If your guest list includes anyone who needs that clearance, ask us to confirm which trailer meets it, or add a standalone ADA accessible porta potty alongside your main trailer. For handwashing beyond the trailer's built-in sinks, a handwashing station rental or portable sink rental adds capacity without waiting in line. See our ADA restroom requirements guide for the full standard.
Can I Rent a Restroom Trailer for a One-Day Event?
Yes, single-day rentals are common for weddings, backyard parties and one-off corporate events, and the day rate for a trailer sits well above a standard unit's day rate because of delivery, setup and pump-out labor. If your event only runs a weekend, ask about the weekend rate rather than booking a full week. Many Great Falls clients booking a wedding restroom rental or a festival restroom rental find the weekend option fits better than a daily or weekly rate. For races and large public gatherings, our marathon and race restrooms and concert restroom rental pages cover trailer plus standard-unit combinations, and golf tournament restrooms and county fair restrooms show how multi-day events scale up trailer count.
What Else Should I Plan Around a Restroom Trailer Rental?
A trailer needs level ground, a nearby water source or a fillable tank, and a generator or shore power depending on the model, so tell us your site conditions when you request a quote. Grease and gray water get pumped separately from the trailer's black tank, and if your event has food service, ask about grease trap pumping too. Larger builds pairing a trailer with dumpsters should look at roll-off dumpster rental or check dumpster sizes and dimensions before ordering. Crews running power tools near the trailer should also confirm GFCI protection per OSHA 1926.404(b)(1)(ii). If your event needs crowd management around the trailer entrance, a temporary fence rental or crowd control barrier rental keeps the line orderly. For ongoing jobs, our monthly porta potty rental page shows how trailer and standard unit costs compare over a longer term, and our request a quote page gets you exact numbers for your date.
How far in advance should I book a restroom trailer in Great Falls?
Book as early as you can, especially for weekend weddings or festival season, since trailers move fast during Great Falls summer events. Two to four weeks ahead is a safe window for most jobs. Emergency needs still get handled through our emergency porta potty rental line.
What is the difference between a 2 stall and 4 stall restroom trailer?
A 2 stall trailer suits under 75 guests over a few hours; a 4 stall trailer handles 75 to 150 guests or a full weekend event. Stall count, not trailer length, is what actually limits your line at the door.
Does a restroom trailer need a water and power hookup?
Most trailers need either a garden hose connection or a fillable onboard tank, plus standard power or a generator. We confirm your site's setup when you book so nothing gets held up on delivery day.
Can a restroom trailer be used in winter in Great Falls?
Yes, with a heated or insulated model and antifreeze in the tanks. Our porta potty in winter guide covers cold-weather setup that also applies to trailers.
How often does a restroom trailer get serviced during an event?
Most multi-day events get at least one service visit per day for pump-out and restocking, more often for high-traffic weekends. Our how often are porta potties cleaned page explains the baseline service interval.
Is a permit required to place a restroom trailer on my property?
Placement in the public right of way needs confirming with the city before delivery. For private property, check our porta potty permit requirements page, and we will flag anything that needs a city sign-off during your quote.
