A 4 stall restroom trailer gives four separate private stalls instead of one, so weddings, block parties and multi-day job sites in Killeen don't run into lines. Daily trailer rates in this market run from 175 dollars up past 2,500 depending on trim level, and weekly rentals bring the per-day cost down. Killeen Porta Pros builds the trailer around your headcount, not the other way around.
Four stalls comfortably cover a wedding of 100 to 150 guests or a construction crew working two shifts, though the right number always comes back to duration and how hard the event runs the units. If you're not sure where your event lands, our guide on how many porta potties you need walks through the math by headcount and hours. Construction sites answer to a different rule: OSHA 1926.51(c) sets toilet ratios by worker count, starting at one facility for 20 workers or fewer. A 4 stall unit often satisfies that ratio for a mid-size Killeen crew without needing a second trailer on-site. For weekend events, pair the math with our event restroom rental page, and if the guest list skews toward a wedding, check wedding restroom rental for stall counts by party size. Ag operations and field crews have their own standard too, covered on farm and agricultural restrooms.
Pricing depends on trim, rental length and delivery distance, and it never runs cheaper as the rental gets longer, so a week always costs more than a day.
| duration | typical range |
|---|---|
| day | 175 to 2,500 |
| week | 150 to 1,650 |
| weekend | 900 to 3,000 |
| event | 2,499 to 3,899 |
A delivery fee applies on top of the trailer rate, generally 100 to 500 dollars for a day rental depending on distance and site access. If your job is out toward Fort Hood, 7.0 miles northwest of Killeen, or Harker Heights, 6.2 miles east, factor that drive into your delivery window. For a full cost breakdown across unit types, see restroom trailer rental cost or the broader porta potty rental cost page. If your budget points toward something simpler, standard porta potty rental and deluxe flushable porta potty sit at a lower price point than a full trailer.
A standard 4 stall trailer is not automatically ADA compliant on its own, and most Killeen events pair one with a separate accessible unit. ADA Standards section 213.2 requires that where portable toilet units are clustered, at least 5 percent must be accessible, with a minimum of one unit regardless of cluster size. That accessible unit needs a 60 inch turning circle under ADA 304.3.1 and a clear door opening of at least 32 inches under ADA 404.2.3. Our ADA accessible porta potty page covers what that unit looks like on delivery, and ADA restroom requirements covers the fuller rule set including route width under ADA 403.5.1. If you're staging a large public event in Killeen, pull both the trailer and the ADA unit onto the same delivery ticket to avoid a second trip.
Handwashing matters too. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not just sanitizer, so check what's built into your trailer versus what needs to ride along separately through handwashing station rental or a standalone portable sink rental. Sites doing painting, coatings or pesticide work should also look at OSHA 1926.51(f)(1), which requires washing facilities for those specific contaminant exposures.
For jobsites already juggling a dumpster or temporary fencing, bundle logistics: see roll-off dumpster rental and temporary fence rental. And if the trailer is destined for a spot in the public right of way, placement needs confirming directly with the city since permit rules aren't standardized across every Killeen site.
Book 2 to 4 weeks out for a standard weekend, longer for wedding season or a Killeen event with a fixed date. Multi-day construction jobs can usually get faster turnaround. Peak weekends fill trailer inventory first, so lock the date before the stall count.
Yes, most trailers carry onboard water and holding tanks, no external hookup required. Ask about tank capacity for your headcount and rental length. Longer events may need a mid-rental service visit to keep tanks from filling before pickup.
Stall count, not much else. A 4 stall restroom trailer suits 100 to 150 guests; an 8 stall restroom trailer doubles that capacity for larger festivals or multi-shift job sites. Compare both against your headcount before booking.
Permit rules vary by site and location within Killeen, so confirm placement with the city before delivery, especially near a public right of way. Our porta potty permit requirements page outlines what to ask. Private property jobs typically move faster.
Yes, if your event or crew needs washing beyond a restroom, a shower trailer rental or luxury restroom trailer covers that need. Ask Killeen Porta Pros which trim fits your site power and water access.
