Let’s be honest, when you’re planning an event, there are a million things on your plate. You’re juggling caterers, entertainment, seating, and a thousand other tiny details. But here’s a secret most event planners learn the hard way: nothing makes or breaks your guests’ experience quite like the bathrooms. Yep, we said it. The humble restroom trailer is the unsung hero of every great event.

You might not notice a top-notch restroom trailer, but you will remember the ones that make you hold your breath and cross your legs. No one wants to wait in a line that wraps around the block, sweat through a heatwave in a stinky porta-potty, or try to gracefully navigate a dark bathroom while wearing a fancy dress.

So, if you want your event to be memorable for all the right reasons, you need to get your restroom game on point. But here’s the catch: not all restroom trailers are created equal, and not all companies have your back like true bathroom heroes.

We’re Mobile Thrones, and we’ve been in the luxury restroom trailer business long enough to know what separates a smooth flush from a total flush failure. This guide will walk you through the key questions you need to ask before booking, so you get exactly what you want: comfort, cleanliness, and a little peace of mind.

1. What Size Trailer Do I Need?

Picking the right size trailer is kind of like picking the right shoes for your event... if you guess wrong, you’re in for a world of discomfort.

Here’s the lowdown:

• Under 100 guests? A 2-stall trailer will probably do the trick.
• 100 to 250 guests? Go for a 3- or 4-stall trailer — your guests will thank you.
• Over 250 guests or multi-day shindigs? Time to think bigger — multiple trailers or larger units.
• 500+ guests? We’ve got you covered with our 12-stall beast, which features:
  • 2 men’s toilets
  • 4 urinals (because guys, right?)
  • 6 women’s toilets
  • Multiple sinks for the hand-washing fanatics
  • A 200-gallon freshwater tank that keeps things running smoothly all day

Pro tip: Don’t just guess your size based on gut feeling (or how many drinks your guests plan to have). Tell us your guest count, event duration, and whether alcohol is flowing. We’ll crunch the numbers and make sure you don’t get stuck in a bathroom bottleneck.

2. How Many Restrooms Do I Need?

This isn’t just a math problem — it’s an art. The number of restrooms depends on:

• How long your event lasts
• What kind of food and drinks are served (we see you, open bar)
• When peak bathroom times happen (usually right before speeches or right after cocktail hour)

Here’s a quick checklist for estimating:

• 1 stall per 50 guests for short events (think: quick ceremony)
• Add more stalls for longer events — nobody likes waiting!
• Multiple trailers in different locations help spread the load and keep lines short

If you’re running a 200-person event that lasts several hours, two smaller trailers placed strategically might be better than one giant one.

3. Is the Trailer ADA-Compliant?

Accessibility isn’t just a nice-to-have; it’s the law (and the right thing to do). Make sure your restroom trailer has:

• At least one ADA-compliant stall — wide doors, grab bars, the works
• Ramps or lifts for easy access
• Spacious interiors for anyone with a stroller, wheelchair, or complicated dress situation

We even have a fancy ADA 6-stall trailer that’s roomy, elegant, and accessible. Because everyone deserves a throne fit for a king or queen.

4. How Are the Trailers Cleaned and Maintained?

Let’s get real — nobody wants to walk into a trailer that smells like last week’s gym socks. So ask:

• How often is the trailer deep cleaned?
• What kind of cleaning products are used? (We’re talking hospital-grade, not just a quick wipe-down.)
• Can you see photos or even check out the trailer before booking?

At Mobile Thrones, we clean like your grandma is coming to visit.Every surface, every time. Because clean trailers = happy guests = event planning karma points.

5. Is the Trailer Climate-Controlled?

You might think climate control is a luxury, but trust us, it’s a necessity. Imagine stepping into a trailer on a 90-degree day without A/C… yeah, no thanks.

Make sure your trailer has:

• Air conditioning for the summer scorchers
• Heating for chilly nights or winter events
• Ventilation fans to keep the air fresh
• Insulated walls to keep temperatures comfy

The goal: your guests should feel like they’re stepping into a clean, comfy bathroom - not a sauna or a freezer.

6. Is Everything Stocked and Ready to Go?

Running out of toilet paper or soap mid-event? That’s a party foul. Confirm your trailer comes stocked with:

• Toilet paper
• Hand soap
• Paper towels or hand dryers
• Hand sanitizer

Extras that show you really care:

• Mirrors
• Hooks or shelves for purses and phones
• Bluetooth speakers for some background tunes (yes, really!)

For multi-day events, ask if restocking is part of the service - no one wants to discover an empty soap dispenser halfway through day two.

7. What Hookups Are Needed?

Not all trailers are created equal when it comes to power and water:

• Does the trailer need to plug into regular electricity, or does it run on a generator?
• Is a water hose hookup required, or does it have its own freshwater tank?
• How long can it run self-contained before needing a refill or recharge?

If your event is off the grid, a remote music festival or a construction site, knowing this is critical.

8. Can It Fit at My Location?

You’d be surprised how often people forget to think about whether a giant trailer can actually get to the spot you want it.

Ask yourself:

• Are the roads or paths wide enough for the trailer?
• Any steep inclines, gravel, or narrow gates?
• Will the trailer fit comfortably without blocking emergency exits or other key areas?

Mobile Thrones can scout your location or work with your planner to make sure the delivery goes smoothly.

9. When Do You Deliver and Who Handles Setup?

This is your moment to relax (sort of).

• Confirm your trailer will arrive early enough to avoid last-minute chaos.
• Will the rental company handle placement, leveling, hookups, and fresh water filling?
• Or are you expected to handle setup? (Spoiler: we do it all for you.)

Our delivery crew shows up like restroom superheroes - leveled, hooked up, stocked, and ready to roll before your guests even arrive.

10. What’s the Full Cost — Really?

Surprise fees are the worst, so get clear upfront on:

• Delivery and setup charges
• Cleaning or pump-out fees (especially for rentals longer than a day)
• Damage waivers or deposits
• Restocking or extension fees

We keep it transparent. No shady “extra fees” lurking in the fine print.

11. Is There a Damage or Cleaning Deposit?

Many companies ask for a deposit in case of damage or extra cleaning needs.

Ask:

• How much is the deposit?
• What could cause deductions? (Spoiler: glitter bombs and chewing gum are usually frowned upon.)
• When and how is the deposit refunded?

Knowing this ahead of time saves headaches later.

12. What If Something Goes Wrong During My Event?

Nobody plans for bathroom disasters, but they happen. What you want is:

• 24/7 support during your rental
• Real people on the other end of the phone, not robots
• Quick fixes for clogs, leaks, power failures, or any other surprises

At Mobile Thrones, we’re standing by to save the day if your event’s restroom hits a snag.

13. Can I Extend or Change My Rental?

Events don’t always stick to the schedule. Ask about:

• Adding rental days if your party runs late
• Cancelation policies and fees
• Upgrading or adding trailers after booking

We get it — flexibility is the name of the game.

Beware providers who:

• Have no photos or videos of their actual trailers online
• Use vague or constantly changing pricing
• Respond slowly or with unclear info
• Lack online reviews or references

You deserve a rental company that’s honest, responsive, and experienced ...someone who treats your event like their own.
