Water, Power, and Wastewater: What a Shower Trailer Rental Needs on Site
The three utilities every shower trailer needs, and how to cover them where the site has none. It covers fresh water, electrical service, and gray-water and wastewater holding for shower trailers and shower-restroom combos, with the questions to answer before delivery at a remote camp, a renovation, or an emergency site where the building's own hookups are out of reach.

Key points
- OSHA's shower rule calls for hot and cold water feeding a common discharge line.
- Shower-restroom combos list 120V/240V, 200A service; confirm the panel before delivery.
- No water line? Water tanks and waste hauling are quoted with the unit.
A shower trailer is a small building with plumbing. Before delivery day, three questions decide where it goes and what comes with it.
Water
Showers need hot and cold water: OSHA's general-industry rule says “Showers shall be provided with hot and cold water feeding a common discharge line” (29 CFR 1910.141(d)(3)). The trailer heats the water; the site supplies it from a hydrant or line, or from water tanks we quote where there's no connection.
Power
Our shower-restroom combination trailers list 120V/240V, 200A electrical service. Tell us what the site panel or generator provides; we confirm the service for the unit you choose before it ships, so hot water is ready on day one.
Wastewater
Graywater and toilet waste go to a sewer or septic connection where one is available, or to holding tanks emptied on a schedule. Send a photo of the placement area and the nearest connections; it often saves a site visit. Where the route is long, as on remote Nevada sites, we plan service visits into the quote.
