What is a shower trailer rental?
A shower trailer is a self-contained bathing unit on wheels, usually paired with a restroom trailer rental or built as a combo unit. It carries its own water supply and wastewater tank, so it does not need a sewer hookup to run, though it does need a water source and often a 200 amp or similar power drop for the water heater and lights. Saint Charles Porta Pros sets these up for construction crews, event organizers and households mid-renovation who need a working shower while the bathroom is torn out. If you are comparing options, a 2 stall restroom trailer or 4 stall restroom trailer can sometimes be paired with a shower unit for larger crews. For teams that want everything under one roof, a luxury restroom trailer often includes shower stalls built in. Pricing depends heavily on trailer size, run length and site access, which is why we walk every site in Saint Charles before quoting.
Why rent a shower trailer instead of a portable shower?
Because a trailer holds more water, serves more people per hour, and does not need constant refilling the way a single-stall shower box does. A shower trailer with its own tank and pump can run a full crew through hot showers on a job site without someone hauling jugs of water all day. This matters most on longer jobs, disaster relief deployments, or multi-day events where a festival restroom rental or concert restroom rental setup already needs to handle heavy foot traffic. Compare that to a standard porta potty rental or deluxe flushable porta potty, which handle waste but not bathing. Households doing a home renovation porta potty project often add a shower trailer once the only working bathroom gets demoed. For disaster response, disaster relief sanitation setups frequently pair a shower trailer with a handwashing station rental so crews get both bathing and quick handwashing between tasks.
How much does a shower trailer rental cost in Saint Charles?
Cost depends on trailer size, rental length and how far the delivery truck has to travel. A short day rental for a small unit sits well under a full week rental, and monthly deployments cost more overall but less per day than renting week to week.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| weekend | 900 | 2000 | 3000 |
| event | 2499 | 3500 | 3899 |
Delivery fees run separately, typically 100 to 172 dollars depending on distance and whether it is a day, week or month deployment. If your job site sits closer to St. Peters, about 6.9 miles west of Saint Charles, or out toward Maryland Heights, 9.4 miles southeast, distance affects the delivery quote. Roll-off delivery trucks need roughly 60 feet of straight clearance behind the truck, and shower trailers need similar room to maneuver and level. For a full cost breakdown across all restroom trailer types, see restroom trailer rental cost, and if portable toilets are also on your list, check porta potty rental cost or the porta potty rental per day page for shorter jobs.
Where can a shower trailer be placed on site?
It needs level, stable ground, a water source, and enough clearance for the delivery truck plus hookup access. ADA Standards section 302.1 calls for floor and ground surfaces that are stable, firm and slip resistant, which applies to the pad the trailer sits on as much as it does to any accessible unit nearby. If your event or job site also needs an accessible restroom, pair the shower trailer with an ADA accessible porta potty; ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent, and never fewer than one, be accessible. Placement in Saint Charles also means checking site access rules before delivery day. Right-of-way placement, if the unit needs to sit near a street, needs confirming with the city since we don't have a specific ordinance to cite here. For general placement guidance across unit types, see the porta potty placement guide and porta potty permit requirements. Construction sites also fall under OSHA 1926.51(c)(1) for toilet counts, so if the shower trailer is part of a larger site sanitation plan, review OSHA portable toilet requirements and construction site services together. Wedding and event clients in Saint Charles often site the shower trailer near a green room or staging tent; see wedding restroom rental and event restroom rental for layout ideas.
How many showers do I need for my crew or event?
It depends on group size and how long people need access. A rough guide: treat shower demand like toilet demand under OSHA 1926.51(c)(1), scaling stalls to headcount. For exact numbers, use the how many porta potties do I need guide as a starting point, then call Saint Charles Porta Pros to size the trailer itself.
Does a shower trailer need a sewer hookup?
No. It runs off its own onboard wastewater tank, the same way a standard portable unit holds a 60 to 70 gallon tank. Saint Charles Porta Pros pumps and services the tank on a set schedule so it never overflows mid-rental.
Can I rent a shower trailer for a weekend event?
Yes. Weekend rentals run as a flat short-term rate rather than a prorated daily rate, and Saint Charles Porta Pros handles delivery, setup and pickup around your event schedule. Ask about pairing it with a festival restroom rental setup.
What power does a shower trailer need?
Most units need a standard power drop for the water heater, lights and pump; larger trailers may need something closer to 200 amp service. We assess power needs during the site walk and can arrange a temporary power pole if the site has no existing hookup.
Is a shower trailer the same as a restroom trailer?
Not always. Some restroom trailers include shower stalls, others handle only toilets and sinks. Check restroom trailer rental or ask us directly which configuration fits your Saint Charles job site or event best.
