San Bernardino County, California
Ontario Shower and Restroom Trailers for Rent for Remote Crews and Recovery Camps
After severe storms, a long highway job or a building closure, someone in Ontario has to keep a crew working without a shower in sight. Our shower and restroom combination trailers bring individual stalls and hot and cold water to a yard or closed site in San Bernardino County. Short-term for an outage, long-term for a build: the term is yours to set. Delivery and setup are coordinated by our team for contractors, agencies and operators renting for work, not for homes. The Sacramento guide adds statewide California detail, and a Ontario quote starts from the address. Our Life Support Service ties a remote camp together: shower and restroom combination trailers at the center, with standalone shower trailers, restroom trailers, laundry trailers, bunk bed sleeper trailers, remote man camp and workforce housing layouts, mobile commercial kitchens, commercial dishwashing trailers, and emergency refrigeration when a walk-in cooler or freezer fails. Call or send a rental brief to check availability and request a quote.

Local context
Ontario: Five Local Facts That Shape a Rental
Five things that shape a rental in this place, each with its public source. Planning scenarios are labeled as scenarios, never as past jobs.
- 01
Past emergencies: FEMA declarations for San Bernardino County
FEMA's declaration records list San Bernardino County among the designated areas for Severe Winter Storms, Straight-Line Winds, Flooding, Landslides, And Mudslides (DR-4699, declared April 3, 2023, incident period February 21, 2023 to July 10, 2023, 46 areas designated in California) and Wildfires (DR-4569, declared October 16, 2020, incident period September 4, 2020 to November 17, 2020, 12 areas designated in California).
Restoration crews need somewhere to wash while a site is closed, and a combination trailer is one option. We claim no past work on this event.

Major construction: recovery projects across California
FEMA's Public Assistance data lists a $6.5 million water control facilities project in California, titled "San Jacinto River Levee Repair", under the Severe Storms And Flooding declaration (DR-4425). Its first federal obligation is dated March 2, 2026. Processing step: "Pending Award". Treat it as a funding record, since it says nothing about current conditions on site.
Other large entries in the same records include "County roads- Repairs completed" (roads and bridges, $5.8 million, DR-4683) and "Sewer Siphon" (public utilities, $5.3 million, DR-4431).
Where crews work for months, washing and restroom access sets the length of the workday, and a combination trailer is one answer. We did not work on this project.

Major renovation: buildings and parks across California
FEMA's Public Assistance data lists a $4.4 million buildings and equipment project in California, titled "Water Treatment Plant", under the Wildfires declaration (DR-4610). Its first federal obligation is dated August 19, 2025. Its processing step is listed as "Obligated", and a funding record cannot tell us what stands on site now.
Further projects in the records: "CalTrans District 5 Facilities Component & Content Damages" (buildings and equipment, $4.0 million, DR-4683) and "Fences To Be Completed (SCL)" (parks and recreational facilities, $3.7 million, DR-4558).
Renovation sites often stay in partial use, so contractors need facilities that do not depend on the building under repair. This is a scenario, not a past job.

Emergency equipment access: reaching Ontario
A California staging-to-hub route is not published in what we checked; we show none rather than invent one.
California traveler information shows current closures and detours, and we plan the delivery route for Ontario with your site contact using live conditions. FEMA's data lists 37 California major disaster declarations since 2012, 14 of them severe storm events. Public emergency operations and our own deliveries are separate.

Local rental costs: what shapes a Ontario quote
Quotes for Ontario are built from four things: which of the three trailer sizes you need, how long you rent, how delivery and setup go, and how wastewater is handled.

Placement
Planning a Ontario site
For a Ontario site, start with the pad, the access and the utilities. Each combination trailer is listed for 120v/240v at 200 amps and needs water and a wastewater route, either a sewer connection or a holding tank with pump-out. We check them with you when you send the address. Whatever the project, a Ontario quote starts from the address, so tell us where in Ontario the trailer is going.
Allow 4 to 6 hours for setup when a ramp is needed and 5 to 15 minutes for stairs; most non-kitchen units take about an hour once the site is ready. Permits and approvals vary by jurisdiction, so check the local rules for San Bernardino County early.
