Restroom Trailer Rentals in the City of Boulder for Any Event, Any Size

It depends on the peak crowd and how long people stay, so we start with those two numbers. One 9-Station handles about 400 to 900 guests over a five-hour event. A VIP tent of 300 usually needs one 5-Station. For bigger areas we line up two or three trailers together with an ADA + 2 at the end, so lines stay short and the whole bank shares one service plan.

On the closest flat, hard surface to the event, with a clear path to the ramp. The ADA + 2 has a self-contained ramp and a roomy accessible room for one guest at a time. City guidance asks for at least 10 percent accessible units and never fewer than one. We check the route from the seats to the ramp before we drop the trailer.

For 200 guests over about five hours, a 5-Station is usually the right size. It covers about 150 to 450 guests. If the bar stays open late or the reception runs past six hours, we may suggest a 9-Station or a second unit. Under 100 guests, a 2-Station or 3-Station is plenty.

Yes, because every unit has air conditioning and heat built in, and the plumbing sits inside the heated body where the cold cannot reach it. For cold-weather events we keep the heat on overnight so the water lines stay safe. In summer we run the AC before guests arrive, so the rooms are cool when the doors open.

We stock every trailer with paper, soap and towels before it leaves our yard, so it is ready the moment the doors open. For events longer than a day, we schedule service visits to pump, clean and restock, often early in the morning before crowds return. An attendant can stay on site for big weddings and VIP areas if you want one. Just ask when you book.

They are very different, because a porta potty is just a plastic box sitting over a holding tank. Our trailers have flushing china toilets, sinks with running water, mirrors, lighting, heat and air conditioning, and separate rooms for women and men. Guests walk up a set of steps into something that feels like a nice restaurant restroom.

Usually, yes, as long as we have a fairly level spot, firm ground and a clear path for the truck to back in and turn around. On a slope we use leveling blocks, and on soft lawn we lay plywood under the wheels. Send us a photo of the spot and the road in, and we will tell you before the delivery day.

Yes, since every unit carries its own fresh water tank and its own waste tank on board. A 5-Station holds 200 gallons of fresh water and 520 gallons of waste, which covers most one-day events. For longer events we refill and pump on a set schedule, so you never need a hose or a sewer line.

You only need one if there is no approved outlet close to where the trailer will sit. Most trailers need one standard 20 amp circuit, and the 9-Station needs two. City rules say a generator must be fenced off from the public and kept at least 10 feet from anything that burns. We arrange a quiet generator and place it to meet those rules.

We can often be there within 1 to 2 hours, and our dispatch line runs 24/7. Restaurants, offices, churches and homes call us when a main break or a wind shutoff closes their restrooms. Because our trailers carry their own water and can run on a generator, you can stay open while the city works on the problem.

Book as early as you can, because graduation weekends, Memorial Day and peak wedding Saturdays from June to September book up first. Even so, call us if you are late. We keep units staged across the Front Range and can often handle same-day delivery when another plan falls through.

Start with what the quote actually includes, line by line, before you look at the total. Look for delivery, setup, pickup, stocking and the number of service visits. If any of those are missing, ask in writing, because they are the lines that get added later. Check the unit name too. A real luxury unit lists its station count, its fresh and waste tank sizes and its power needs. A quote that only says “luxury unit” may be a plastic stall with a sink. Ask who owns the trailer. A broker will often quote low and then pass your date to whoever has a unit free that weekend.

Next, check the plan for the hard parts of a Boulder site. Who brings power if there is no outlet near the lawn? Who levels the trailer on a sloped meadow? What happens if a storm moves the event inside for an hour? A good quote answers those questions before you ask. Send any quote you have to us, and we will mark up what is missing for free. You do not have to book with us to get that help.

Begin with the permit timeline, because it sets the pace for everything else on your list. The City of Boulder Office of Special Events accepts applications up to 364 days ahead, and a liquor permit needs at least 60 days. Count your peak crowd, not your total, and plan about one toilet per 100 people at peak, with at least 10 percent accessible. Then mark the restroom spot on your site plan, on pavement or plywood, with a clear path from the main crowd and a separate path for the service truck.

Then sort out water and power. Park water and outlets need written approval, so a self-contained trailer saves a step. If you need a generator, plan a fenced spot at least 10 feet from tents and hay bales. Finally, set the service plan: when we stock, when we pump on a multi-day event, and who on your team calls our dispatch line if something runs low.

A long remodel is where a temporary restroom trailer pays off quietly, even though nobody at the event ever thinks about it. When a restaurant or an office loses its restrooms for weeks during a remodel, staff and guests still need a place to go. A 2-Station or 3-Station by the back door keeps the business open. On new construction, owner and architect teams want a real bathroom near the site office, not a plastic stall at the edge of the dirt.

For crews, federal rules set the floor. OSHA 29 CFR 1926.51 covers how many toilets a job site needs by crew size. Our ADA + 2 handles job sites up to about 30 crew members. We set a weekly service day that fits your schedule, swap units if your crew grows and keep the heat on through the winter months so pipes never freeze.

Outages happen in Boulder more than people expect. In August 2026 a main break near South and Graham streets left customers without water and put part of the city under a boil advisory. In December 2025, Xcel Energy cut power to parts of the city during a Red Flag wind event, and restoring it could take a few days. Restrooms close fast when either happens, and a business without working restrooms usually has to close its doors.

Call us first and give us the street address, the number of people on site and whether you have power. Our trailers bring their own water, so a main break does not stop them. If the power is out too, we bring a generator. We can often be there within 1 to 2 hours, and we stay until the water and power are back. Keep our number with your emergency plan so the call takes a minute, not an hour.

Match the trailer to the size of the crowd and the length of the event before you look at anything else. The 2-Station has one room for women and one for men and fits backyard parties and small weddings. The 3-Station adds a second women’s room. The 5-Station covers about 150 to 450 guests, and up to about 500 for a five-hour event. The 9-Station handles about 400 to 900 guests and needs two 20 amp circuits.

Style matters for some events. The 8-Station Private Stall Deluxe gives each guest a private, lockable room, which fits black tie receptions and corporate dinners. Need an accessible room? Add an ADA + 2 or pick the ADA + 6. If you are unsure, tell us the guest count, the hours and whether there is a bar, and we will recommend the right mix.
