How much does a restroom trailer rental cost?
Daily rates for a trailer at Lawrence Porta Pros run from 175 to 2,500 dollars depending on stall count and finish level, with weekly rentals landing between 150 and 1,650 dollars. Weekend rates for a full weekend booking typically fall between 900 and 3,000 dollars, and multi-day events often run 2,499 to 3,899 dollars flat. A basic 2 stall restroom trailer costs less than an 8 stall restroom trailer built for a wedding or fair crowd. Delivery adds a separate fee, usually 100 to 500 dollars for a single day drop or 50 to 150 dollars a week for longer jobs. For a full cost breakdown by trailer size and season, see our restroom trailer rental cost page, and compare against our porta potty rental cost guide if you are weighing a standard unit against a trailer for a Lawrence job site.
| unit | day | week | weekend | event |
|---|---|---|---|---|
| trailer | 175-2500 | 150-1650 | 900-3000 | 2499-3899 |
Longer bookings cost more in total but less per day. A 4 stall restroom trailer rented for a week runs less per day than the same unit booked for a single weekend, since weekend rates carry a premium for quick turnaround delivery and pickup.
What is a restroom trailer and how is it different from a porta potty?
A restroom trailer is a towable unit with flushing toilets, sinks, and often climate control, built for events and job sites that need something closer to a real bathroom. Unlike a standard porta potty rental, which uses a 60 to 70 gallon holding tank and stands about 92 inches tall on a 44 by 48 inch footprint, a trailer has multiple private stalls, running water, and interior lighting. Some units qualify as a luxury restroom trailer, with finished counters and climate control for weddings held anywhere from downtown Lawrence to a barn venue outside town. If your event needs washing beyond toilets, a shower trailer rental adds shower stalls to the same trailer chassis. Compare this against a deluxe flushable porta potty if your budget calls for flushing without the full trailer footprint, or an ADA accessible porta potty if you need a single accessible unit rather than a full trailer.
How many stalls do I need for my event?
Stall count depends on guest count and event length, and OSHA 1926.51(c) sets the baseline ratio for construction crews at one toilet facility per 20 workers or fewer, scaling up as headcount grows. Events do not fall under that construction standard directly, but planners in Lawrence still use similar ratios to avoid lines. A 2 stall restroom trailer works for a backyard wedding or a crew of 20 to 30 people over a weekend. Jump to a 4 stall restroom trailer for a mid-size festival or a job site running two shifts, and step up to an 8 stall restroom trailer for a county fair or a race with a few hundred participants passing through over a day. For a full sizing walkthrough tied to guest counts, use our how many porta potties do I need guide, which applies to trailers too. Larger festivals sometimes combine a trailer with several standard porta potty rental units to spread out lines across the grounds.
Is a restroom trailer ADA accessible?
Not every trailer configuration meets accessibility standards, so ask before you book if you need one. ADA Standards section 213.2 requires that where single-user portable units are clustered, at least 5 percent, and never fewer than one, must be accessible. ADA Standards section 404.2.3 sets a minimum clear door opening of 32 inches, and section 403.5.1 requires a 36 inch clear route to the unit. A dedicated ADA accessible porta potty is often the simpler fix alongside a standard trailer, especially for outdoor venues around Lawrence with uneven ground. ADA Standards section 405.2 also caps ramp slope at 1:12 if the trailer requires a ramp for entry, and section 304.3.1 calls for a 60 inch turning circle inside an accessible stall. Confirm accessible unit placement when you book, since not all trailer models on the market include a stall built to these dimensions.
What do I need to prepare before delivery?
Delivery crews need clear, level ground and enough room to maneuver the trailer into place. A roll-off style delivery needs about 60 feet of straight clearance behind the truck, and restroom trailers need similar approach room since they arrive on a towed chassis. If your trailer needs a water hookup or holding tank service, plan for that connection point ahead of time, especially for multi-day events. Some Lawrence properties also need power nearby if the trailer includes lighting or climate control beyond battery capacity, so check our temporary power pole page if your site lacks an outlet. Sites without existing water access sometimes pair a trailer with a separate handwashing station rental or portable sink rental to cover overflow demand during peak hours. If you are also renting a temporary fence rental to secure the event perimeter, coordinate both deliveries on the same day to cut down on site visits.

For jobs based right in the city, our porta potty rental Lawrence page covers standard unit pricing and delivery windows alongside trailer options.
Do I need a permit to place a restroom trailer on my property?
Permit rules vary by property type and location, and placement in the public right of way needs confirming with the city before delivery. Private property setups, like a backyard wedding or a construction lot already zoned for work, typically move faster than street-adjacent placements. Check our porta potty permit requirements page for a general rundown, and review our porta potty placement guide for guidance on ground surface and clearance before the trailer arrives. Construction sites already following OSHA portable toilet requirements usually have permitting sorted out as part of their site plan, but event organizers should confirm early since city requirements differ from ordinary porta potty placement. If your event includes a stage or vendor booths, our festival restroom rental and event restroom rental pages cover other logistics worth checking at the same time.
How far in advance should I book a restroom trailer?
Book as early as you can, especially for weekend weddings or fall festivals when trailers book up fastest. Four to six weeks ahead is a safe target for most events. Last-minute needs still get handled through our emergency porta potty rental page, but stall selection narrows the closer you get to the date.
What is the difference between a 2 stall and 4 stall restroom trailer?
A 2 stall restroom trailer suits smaller gatherings, roughly 50 guests or a small crew over a weekend. A 4 stall restroom trailer handles double that traffic comfortably, cutting wait times at weddings, fairs, or job sites running longer shifts across a full day.
Does a restroom trailer need to be hooked up to water?
Most trailers carry an internal fresh water tank and do not require a hookup, though some larger luxury units accept one if available on site. Ask your rental provider which configuration your chosen trailer uses before delivery day, since it affects setup time and placement options.
Can I rent a shower trailer along with a restroom trailer?
Yes, a shower trailer rental can be delivered alongside a restroom trailer for multi-day events, disaster relief work, or work crews staying on site for extended stretches. Many shower and restroom combination units share plumbing systems, which simplifies setup and reduces the total footprint needed on site.
How often is a restroom trailer serviced during a multi-day event?
Service frequency depends on guest count and trailer size, similar to the ANSI/PSAI Z4.3 baseline interval used for standard portable units. High-traffic events usually need daily servicing to keep tanks from filling and handwashing stations stocked, while smaller weekend gatherings may only need one visit.
Is a restroom trailer better than multiple porta potties for a wedding?
It depends on budget and venue style. A wedding restroom rental trailer offers a nicer guest experience with running water and enclosed stalls, while several standard porta potty rental units cost less and work well for casual or outdoor-only venues around Lawrence.
