Hiring the wrong portable restroom company can turn a great event into a sanitation disaster. Whether you're planning a wedding, construction site, or festival, asking the right questions upfront saves money, prevents headaches, and ensures your guests have decent facilities. Here's exactly what to vet before signing a contract.
How Many Units Do You Actually Need?
This is the most common mistake—guessing instead of calculating. A general rule: one standard unit per 100 guests for a 4-hour event, or one per 50 guests if the event runs 8+ hours. For construction sites, OSHA recommends one portable toilet per 20 workers. Ask the company for a needs assessment based on your specific event type, duration, and guest count. They should ask you detailed questions, not just quote you a number off the top of their head.
If your event includes alcohol, you'll need roughly 25% more capacity. Similarly, if you're hosting families with children, plan extra units since kids take longer and may need smaller-sized facilities. The rental company should help you think through these variables—it's a sign of expertise when they do.
What's Actually Included in the Quote?
Portable restroom pricing varies wildly, and the base rental fee is just the start. Ask for a complete breakdown:
- Unit delivery and pickup: Some companies charge separately; others bundle it.
- Weekly servicing: Multi-day events require mid-event pumping ($75–$200 per pump-out, typically).
- Toilet paper, soap, and hand sanitizer: Included or extra?
- Cleaning and disinfection: Standard for one-event rentals, but confirm it's in the contract.
- Restocking fees: If supply runs out, do they charge to refill it?
- Damage fees: What happens if a unit comes back damaged? Get this in writing.
Average costs range from $150–$300 per unit for a weekend event, but multi-day rentals drop to $75–$150 per unit per day. Construction sites may negotiate longer-term rates. Always request an itemized written quote before committing.
How Will Units Be Maintained During the Event?
A filthy portable restroom reflects on you, not the rental company. Ask:
- How often will staff service the units? For events under 8 hours with moderate attendance, once is enough. For festivals or 24-hour sites, twice daily is standard.
- What does servicing include? Pumping waste, restocking supplies, cleaning surfaces, and checking equipment.
- Who monitors during off-hours? Late-night events need clear communication on emergency contact and response time.
- Do they supply feminine hygiene products and seat covers? Not all companies do—confirm now.
Request that the company supply a contact person's direct phone number for the day of your event. If something breaks down or runs out of supplies, you need someone to reach immediately.
What's the Company's Track Record?
Don't just trust marketing copy. Ask for and actually call three recent references from events similar to yours (same size, type, and duration). Specifically ask referees: Did units arrive and leave on time? Were they clean? Were problems resolved quickly?
Check online reviews on Google and the Better Business Bureau, but weight recent reviews more heavily—a company's service level can change. If they operate in your area via platforms like Mercoly, you can compare trusted providers side by side and see verified ratings from customers like you.
Ask how long the company has been operating and whether they're licensed and insured. A one-person operation might be cheap, but if they ghost you on event day, you're stuck.
What Happens if Something Goes Wrong?
Clarify cancellation and contingency policies:
- If you need to cancel, what's the refund timeline?
- If a unit breaks down, do they have backup units available? (Reputable companies keep spares on hand.)
- If they don't show up, what compensation do you get?
- What weather conditions affect service? Extreme cold can freeze tanks; extreme heat can affect odor control.
Get these terms in a signed contract. Verbal promises mean nothing on the morning of your event.
