What is a shower trailer and how does it work?
A shower trailer is a self-contained unit with its own water supply, water heater, and drainage tank, built so people can shower without hooking into a building. South San Francisco Porta Pros delivers it, levels it, and connects it to a water source or fills the onboard tank, depending on the site. Some jobs need temporary power pole service to run the heater and lights if there is no power on site, and a light tower rental helps if the trailer sits somewhere with no fixed lighting after dark. These trailers pair well with a restroom trailer rental so people are not walking between two different setups. For crews already running portable restroom rental units on site, adding showers is usually a short conversation, not a redesign. Wash water still needs somewhere to go, and OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, which is why we check the water source before delivery day, not after.
How much does a shower trailer rental cost in South San Francisco?
Cost depends on stall count, trip length, and how far the trailer travels to get there. Below is the general band; ask us for a written number tied to your dates before you commit.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | 175 | 800 | 2500 |
| Week | 150 | 1397 | 1650 |
| Weekend event | 900 | 2000 | 3000 |
| Multi-day event package | 2499 | 3500 | 3899 |
A delivery fee applies on top of the trailer rate, and that separate charge typically runs 100 to 150 dollars for a single day or 50 to 150 dollars if billed as part of a weekly rental. If you're comparing this against standard units, our porta potty rental cost page and porta potty rental per day page break down the smaller footprint options, and restroom trailer rental cost covers the toilet-only trailers if a shower isn't actually what the job needs.
Why rent a shower trailer instead of a standard portable toilet?
Because some jobs need real washing, not just a toilet. Wildfire and flood response crews, agricultural labor camps, film sets, and multi-week construction jobs in South San Francisco all reach a point where a porta john rental alone doesn't cover it. If your crew is applying paints, coatings, herbicides, or insecticides, OSHA 1926.51(f)(1) specifically requires washing facilities for that work, and a shower trailer satisfies that need directly instead of sending workers offsite. Agricultural operations fall under OSHA 1928.110, which calls for potable water, toilets, and handwashing within a quarter mile walk of hand-labor employees, and a shower trailer parked near the field does double duty there. For disaster response, our disaster relief sanitation page covers deployment timelines, and farm and agricultural restrooms covers the field-labor side in more depth. Weddings and events sometimes rent these too, more for glamping-style comfort than any code requirement. Check our wedding restroom rental and event restroom rental pages if that's the use case.
Where can a shower trailer be placed on site?
It needs level ground, a water hookup or fillable tank access, and enough clearance for the delivery truck to back in. We generally want about 60 feet of straight clearance behind the truck, the same requirement we use for roll-off dumpster rental deliveries, since both are towed or hauled into place the same way. Placement in the public right of way needs confirming with the city before delivery day; we do not guess on that. If your site also needs debris hauled, look at construction dumpster rental or dumpster sizes and dimensions to plan both deliveries together. For accessible stalls, ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible, with a minimum of one, and our ada accessible porta potty page has the specifics if your shower trailer needs an ADA-compliant stall alongside it. Sites near San Bruno, about 5.5 miles southwest, or Millbrae, 7.2 miles south, get the same delivery windows as jobs inside South San Francisco proper, so distance rarely changes the timeline much.
How many shower stalls do I need?
Depends on headcount and how long people are on site. A 2 or 3 stall trailer covers a small crew or short event; larger disaster relief or labor camps need more stalls and a faster turnaround on water refills. Talk to us before booking, we'll size it to your actual roster, not a guess.
Does the shower trailer need to be hooked up to water?
Not always. Many trailers carry an onboard tank that we fill and refill on a schedule, though a direct hookup lasts longer between service visits. If your site has a spigot or hydrant access, tell us when you book so we bring the right connection kit.
Can I rent a shower trailer for just one day?
Yes. A single day rental exists mainly for short events or emergency situations. Weekend and weekly rates work out cheaper per day than booking single days back to back, so tell us your real date range up front.
Is delivery included in the shower trailer price?
No, delivery is billed separately from the trailer rate. It depends on distance and how long the trailer stays, so ask for that number specifically when you request your quote through our request a quote page.
Do I need a permit for a shower trailer in South San Francisco?
Permit rules vary by placement, especially near a public street or sidewalk, and that needs confirming directly with the city. See our porta potty permit requirements page for the general process, then call us and we'll help you sort out what applies to your specific site.
