How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably covers a mid-size crew or guest list without a line forming at the door. On a jobsite, construction site services crews often pair a 4 stall unit with standard porta potty rental units for overflow, since OSHA 1926.51(c) sets ratios of one toilet facility per 20 workers on a crew of 20 or fewer, and one seat plus urinal per 40 workers above that. For events, a wedding restroom rental or festival restroom rental booking usually lands a 4 stall trailer for guest counts in the 100 to 250 range, more if you add a second unit or a 2 stall restroom trailer for satellite parking. Larger crowds should look at the 8 stall restroom trailer instead. Every trailer needs potable water on site per OSHA 1926.51(a)(1), and Lexington-Fayette Porta Pros fills the tank at delivery so you are not scrambling for a hose bib.
What Does a 4 Stall Restroom Trailer Cost in Lexington-Fayette?
Pricing depends on duration and finish level. Basic units run lower than the climate-controlled, wood-trim trailers booked for weddings.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Event (multi-day) | $2,499 | $3,500 | $3,899 |
A delivery fee applies separately, generally between 100 and 500 dollars for a single day and up to 420 dollars for a month-long rental. See the full breakdown on restroom trailer rental cost or compare against porta potty pricing at porta potty rental cost. If you only need something for a Saturday afternoon, check porta potty rental per day before committing to a trailer-sized budget. Long jobsite runs are cheaper per day than a single weekend rental, so ask about monthly porta potty rental style terms if your project runs past a few weeks.
Does a 4 Stall Trailer Meet ADA Requirements?
Standard 4 stall trailers are not automatically ADA accessible, so ask before you book if you need a compliant unit. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent, and never fewer than one, must be accessible, and that logic carries over to trailer setups serving the public. An accessible unit needs a 36 inch clear route per ADA Standards section 403.5.1, a 32 inch door opening per section 404.2.3, and a 60 inch turning circle inside per section 304.3.1. For a dedicated compliant unit, pair your trailer with an ADA accessible porta potty rather than assume the trailer covers it. Full detail lives on ADA restroom requirements. Ramped entries, where used, follow a 1:12 maximum slope under section 405.2.
Placement in Lexington-Fayette needs a level, firm pad, ideally paved or gravel, since ADA Standards section 302.1 calls for stable, slip resistant ground even where the unit itself is not a compliance-rated stall. Sites near Nicholasville, 15.3 miles southwest, or Versailles, 15.7 miles west, get the same delivery standard. If your event sits in the public right of way downtown, placement needs confirming with the city; we do not guess at that rule. See porta potty placement guide and porta potty permit requirements before finalizing your site plan.
How far in advance should I book a restroom trailer?
Two to four weeks ahead is safe for most weekends. Wedding season and county fair dates near Winchester, 18.0 miles east, book faster. Call sooner if you need a specific finish level or ADA-paired unit, since fewer high-end trailers are in rotation than standard porta potties.
Can the trailer run without a water hookup?
Yes. Most 4 stall trailers carry an onboard freshwater tank and holding tank, so no external hookup is required for short events. Longer jobsite rentals sometimes tie into a hose bib to reduce service visits, but it is not mandatory.
What is the difference between a 4 stall and a 2 stall trailer?
A 2 stall restroom trailer suits smaller gatherings under 100 guests. Four stalls moves more people through faster and usually includes separate men's and women's sides, which cuts wait times at weddings and multi-day events.
Do I need a permit for a restroom trailer in Lexington-Fayette?
It depends on placement and event size. Right-of-way or large public event placements need city confirmation. Check dumpster permit requirements style logic applies here too. We recommend calling ahead rather than assuming.
How often is the trailer serviced during a multi-day rental?
Service intervals follow ANSI/PSAI Z4.3 guidance, generally weekly for lighter use, but multi-day events with heavy traffic get serviced daily. Lexington-Fayette Porta Pros schedules service based on guest count and trailer tank size at booking.
