What comes on a 4 stall restroom trailer?
Four private stalls, running water, and interior lighting, all pulled behind a standard trailer hitch. Gaithersburg Porta Pros sets these units up for weddings, festivals, and construction crews around Gaithersburg who've outgrown a bank of portable toilet rental units but don't need the size of an 8 stall restroom trailer. If your event has flushable fixtures on the wish list, the deluxe flushable porta potty line is worth a look too, though the trailer format is roomier. Accessibility matters here: ADA Standards section 404.2.3 sets minimum clear door opening width at 32 inches, and ADA Standards section 304.3.1 calls for a 60 inch turning circle, so ask about an accessible unit if any guest or worker needs one. For crowds larger than four stalls can serve comfortably, compare against a 2 stall restroom trailer or step up to the luxury restroom trailer line. Delivery into most Gaithersburg neighborhoods is straightforward, but a roll-off style clearance behind the drop point, about 60 feet of straight run, makes placement faster for our drivers.
How much does a 4 stall restroom trailer cost in Gaithersburg?
Pricing depends on whether you need it for a day, a weekend, or a full week. Weekly rentals for trailer-class units run roughly 150 to 1,650 dollars, and multi-day events push into the higher bands. Full breakdown below, and if you want the general cost picture across all restroom options, see restroom trailer rental cost or the broader porta potty rental cost page.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| weekend | 900 | 2000 | 3000 |
| event (multi-day) | 2499 | 3500 | 3899 |
A delivery fee applies on top, typically 100 to 500 dollars depending on distance and access. If you're comparing against a straight daily porta potty rate, check porta potty rental per day for context, or monthly porta potty rental if this is a long-term site need.
Is a 4 stall restroom trailer enough for my event?
Depends on your headcount and how long people will be on site. OSHA 1926.51(c)(1) sets construction toilet ratios at one facility per 20 workers for crews of 20 or fewer, scaling up from there, and that's a reasonable planning baseline even for events. Four stalls comfortably serve a mid-size wedding or a crew of 30 to 50 for a single shift. Use our how many porta potties do I need guide to size it exactly, and if you're running a construction job rather than a party, the OSHA portable toilet requirements page walks through the full ratio table. Weddings near Gaithersburg often pair a trailer with a handwashing station rental for guest convenience; 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not just sanitizer. For outdoor festivals, see festival restroom rental or event restroom rental for planning specifics. Gaithersburg sites near Flower Hill, about 1.9 miles northeast, and Montgomery Village, 3.9 miles north, are both within our regular delivery routes, as is Derwood at 4.1 miles southeast.
How far in advance should I book a restroom trailer?
Two to four weeks ahead is safest, especially for weekend weddings when trailer-class units book up fast around Gaithersburg. Rush orders happen, but you'll have more stall and finish options if you call early. See request a quote to lock in a date.
Does the trailer need a power hookup?
Interior lighting and water pump run off a small onboard system on most units, though some larger trailers want a standard outlet nearby. Ask when you book so delivery day goes smoothly. Check temporary power pole if your site has no power at all.
Can I place the trailer on grass or gravel?
Yes, as long as the ground is reasonably level and firm. ADA Standards section 302.1 calls for stable, firm, slip-resistant surfaces on accessible routes, which matters if an accessible unit is part of your order. Our porta potty placement guide covers ground prep in more depth.
Do I need a permit to place a restroom trailer in Gaithersburg?
Placement in the public right of way needs confirming with the city before delivery day. For anything set back on private property, a permit usually isn't required, but check porta potty permit requirements before you finalize a curbside spot.
What's the difference between this and a luxury trailer?
Finish level and fixture count. A 4 stall unit covers the basics well; a luxury restroom trailer adds upgraded interiors and climate control for higher-end weddings or corporate events. Both run through the same request a quote process.
