Restroom trailer rental in San Rafael runs from around 175 dollars a day for a small unit up to 3,899 dollars for a multi-day event package on a luxury trailer. A 2-station trailer for a weekend job costs less than an 8-stall VIP unit booked for a wedding. Your final number depends on stall count, trip length and how far San Rafael Porta Pros has to haul the tank.
Day rates for restroom trailer rental start at 175 dollars and climb past 2,500 depending on size and finish level. Weekly rentals land closer to 1,397 dollars on average, and a full event package, the kind booked for a three-day festival, typically runs 2,499 to 3,899 dollars. A basic 2 stall restroom trailer costs less per day than a 4 stall restroom trailer, and both sit well under an 8 stall restroom trailer built for large crews or big guest counts. Weekend rates for trailers generally fall between 900 and 3,000 dollars, so a Saturday wedding at a Marin venue costs differently than a five-day construction pull in downtown San Rafael. If you just need a bathroom without the trailer chassis, a standard porta potty rental or a deluxe flushable porta potty is the cheaper path, and our restroom trailer rental cost numbers only apply once you need real stalls, sinks and climate control on wheels.
| unit | day | week | weekend | event |
|---|---|---|---|---|
| trailer (standard/2-stall) | 175-2500 | 150-1650 | 900-3000 | 2499-3899 |
| ADA add-on unit | 200-400 | 120-240 | 199-300 | -- |
Delivery is billed separately in most cases, and a delivery fee for a single day can run 100 to 500 dollars depending on distance and site access. San Rafael crews working near San Anselmo, 4.3 miles west, or Larkspur, 5.1 miles southwest, usually pay toward the lower end of that range since the truck run is short.
A 2-station trailer gets you two private stalls, sinks with running water, and typically interior lighting, all built onto a towable chassis instead of a fixed footprint. That is the core difference from a standalone portable toilet rental: plumbing and finish, not just a holding tank. Handwashing inside most trailers meets the intent of 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device at any washing facility, since sanitizer alone does not satisfy that standard. If your event also needs a standalone wash station near a food booth or paint area, add a handwashing station rental instead of relying on the trailer's interior sinks. Site prep matters too. A roll-off dumpster delivery needs about 60 feet of straight clearance behind the truck, and trailers need similar backing room, so tight downtown San Rafael lots or narrow residential driveways should be measured before delivery day. For crowd management around trailer entrances at outdoor events, pair the rental with a temporary fence rental or crowd control barrier rental to keep the line orderly and the unit's steps clear.
VIP and luxury trailers add finish work, not just extra stalls: real flooring, mirrors, climate control and sometimes running hot water, which pushes both the day rate and the multi-day event rate higher than a basic 2-stall unit. A luxury trailer booked as a day rental can run anywhere from 85 dollars for a very small unit up to 1,200 dollars for a full VIP build, while an event-length luxury booking sits in the 2,499 to 3,899 dollar band. Compare that to the deluxe flushable porta potty line, which offers flushable convenience without the trailer shell, at a lower day rate. For weddings at Marin venues or corporate events downtown, the luxury restroom trailer is often worth the premium because guests notice finish quality more than they notice stall count. If your event needs showers as well as toilets, a shower trailer rental is priced and quoted separately from a standard restroom trailer. San Rafael event planners should also check ADA restroom requirements: ADA Standards section 213.2 requires that at least 5 percent of clustered single-user units be accessible, with a minimum of one, so budget an ADA accessible porta potty or ADA trailer stall into the headcount.
Yes. Construction jobs typically rent by the week or month at flatter rates, while events pay day or weekend pricing that runs higher per day but covers a shorter window. A construction site services job in San Rafael might keep a trailer for weeks at the weekly rate near 1,397 dollars, spreading the delivery fee over more use days. OSHA 1926.51(c) sets worker toilet ratios for construction sites, starting at one facility for 20 workers or fewer, which is the baseline our crews use when sizing a job alongside a portable restroom rental quote. Event bookings, by contrast, often need the trailer for a single Saturday, so the weekend rate applies instead, and that number is quoted directly rather than pulled from a table. If your timeline is still open, compare against a monthly porta potty rental or check general porta potty rental cost guidance before committing to trailer-specific pricing.
Two to four weeks is safe for most weekend events; peak wedding season and county fair dates fill faster. For a same-week need, ask about emergency porta potty rental or emergency trailer availability, since standard lead times can slip during busy months.
Usually not folded into the base rate. Delivery fees run 100 to 500 dollars for a single day and less per day on longer rentals, so a week-long job often costs less per day delivered than a one-day event trailer.
Yes, and ADA units should be requested at booking, not added later. ADA Standards section 304.3.1 requires a 60 inch turning circle inside accessible units, and 404.2.3 sets a 32 inch minimum clear door opening.
A weekly or monthly rate beats stacking day rates. Standard monthly pricing for portable units runs 125 to 325 dollars, and pairing that with a porta john rental for overflow crew members often costs less than a bigger trailer.
Most self-contained trailers carry their own tank and battery lighting, but larger VIP units may want a power connection. Ask about a temporary power pole if your San Rafael site lacks accessible outlets.
