A 4 stall restroom trailer gives Nashville events and job sites four private stalls in one unit, and it rents by the day, week or event depending on how long you need it. Nashville Porta Pros stocks these for weddings, festivals and crews who have outgrown a bank of standard porta potty rental units.
Four stalls handle a wedding of 150 guests comfortably for an evening, or a mid-size construction crew across a full week. For steady daily use, OSHA 1926.51(c) sets the baseline: one toilet facility for 20 workers or fewer, then additional fixtures as headcount climbs past 20. That ratio is why a lot of Nashville contractors pair a 4 stall unit with a couple of standard porta potty rental units instead of scaling up to an 8 stall restroom trailer too soon. Event planners run different math, closer to the guidance on our how many porta potties do I need page, since guests cycle through faster than a crew does. If you are torn between trailer sizes, our 2 stall restroom trailer page and restroom trailer rental hub both break down the step up in capacity, and the luxury restroom trailer option covers weddings that want finished interiors instead of a working job site unit.
Trailer pricing swings hard depending on how many days you book and whether it is an event weekend or a standard work week. Nashville Porta Pros prices by the day, the week or the event, and delivery is billed separately based on distance and site access.
| Duration | Typical range |
|---|---|
| Day | $175 to $2,500 |
| Week | $150 to $1,650 |
| Event (multi-day) | $2,499 to $3,899 |
A weekend booking generally runs from around $900 up to $3,000 depending on trailer condition and add-ons. Delivery adds a separate fee, and our restroom trailer rental cost page walks through what drives that number up or down. If budget is the main question, compare against a simpler setup on the porta potty rental cost or porta potty rental per day pages before committing to a trailer.
It needs level, firm ground and clear approach room for the delivery truck. A roll-off style delivery needs about 60 feet of straight clearance behind the truck to back in and level the unit, so a tight downtown Nashville lot or an alley job site may need a walk-through first. ADA Standards section 405.2 caps ramp slope at 1:12 if the site is not flat, and section 403.5.1 calls for a 36 inch clear route to the door. Our porta potty placement guide covers ground prep in more depth, and porta potty permit requirements is worth a look if the trailer sits in a public right of way. If you are running a job site instead of an event, pair placement planning with construction site services and check power needs against temporary power pole if the trailer has electric flush and lighting.
Nashville venues near Berry Hill, 4.4 miles south, and Oak Hill, 9.3 miles south, book these often for outdoor receptions. Crews working sites out toward Brentwood, 15.3 miles south, or La Vergne, 18.7 miles southeast, tend to keep the trailer for a full week rather than a single day. For weekend weddings specifically, see wedding restroom rental and event restroom rental; for larger festival crowds, festival restroom rental and concert restroom rental go into headcount math a 4 stall unit cannot cover alone.
Most units carry an onboard tank and run on standard household power, but larger trailers with multiple sinks may need more. OSHA 1926.51(a)(1) requires potable water at the jobsite, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at any washing station, hand sanitizer does not count.
Sometimes, but check your headcount against OSHA 1926.51(c) first. Under 20 workers, one facility works fine; past that, add fixtures. Many Nashville crews run a trailer for breaks and keep a few standard porta potty rental units scattered near the actual work zones.
Book as soon as your date is set, especially for weekend weddings and festival season. Trailers move fast during peak Nashville event months, and short-notice availability shrinks. Use request a quote to lock a date early.
Not automatically. ADA Standards section 213.2 requires at least one accessible unit in a cluster of single-user toilets, and section 304.3.1 calls for a 60 inch turning circle. Ask about an ADA accessible porta potty add-on if guests need it.
Stall count and line speed. Four stalls suit mid-size weddings or crews under 20 people; an 8 stall restroom trailer handles bigger festivals or larger job sites where wait times matter more.
