How to Choose the Right-Sized Restroom Trailer for Your Needs

Aug 14

When you’re planning an event or managing a job site, choosing the right-sized restroom trailer is more than a convenience — it’s the difference between smooth operations and long bathroom lines. The right fit keeps guests comfortable, ensures compliance with local requirements, and helps you stay on budget.

At Marquee Lavs, we help clients across Massachusetts and Rhode Island choose restroom trailers that match their exact needs. Here’s a step-by-step guide to finding the right size.

1. Consider Your Guest or Crew Count

The first step is knowing how many people will use the restroom trailer. A general rule of thumb:

2-Stall Trailer – Ideal for events with up to 150 guests for 4–6 hours.
3-Stall Trailer – Works for 150–250 guests, or smaller weddings where comfort is key.
4–5+ Stall Trailers – Perfect for larger gatherings, festivals, or high-traffic corporate events.
ADA-Compliant Units – Required if accessibility is needed for guests or workers.

Pro tip: If your event serves alcohol, expect restroom use to increase by 15–20%.

2. Match the Trailer to Event Duration

Short events can get by with fewer stalls if traffic is well-managed. Long-term rentals—like construction sites—need trailers built for durability, daily cleaning, and ongoing servicing.

At Marquee Lavs, our long-term restroom rentals are designed for heavy use, with climate control and regular pumping schedules to keep conditions comfortable year-round.

3. Factor in Location & Space Constraints

Before booking, measure your site access and available footprint. Restroom trailers need level ground, space for towing access, and proximity to water and power connections (or opt for self-contained models with water tanks and generators).

4. Balance Comfort with Budget

Choosing the smallest trailer to save money might seem smart—but long lines and overworked facilities can leave guests frustrated. On the other hand, oversizing unnecessarily can eat into your budget. Our team can help you right-size based on actual usage patterns, ensuring both comfort and cost-effectiveness.

5. Think About the Experience You Want to Create

If your event is a wedding, corporate gathering, or VIP area at a festival, the restroom experience should match the tone. Luxury restroom trailers offer soft lighting, stylish interiors, and upscale amenities that go beyond basic sanitation.

Final Word

Choosing the right-sized restroom trailer comes down to guest count, event duration, site conditions, and the overall experience you want to deliver.

At Marquee Lavs, we take the guesswork out of it. From small, intimate gatherings to large-scale events, we’ll recommend the perfect size and style to keep things running smoothly.
