Shower trailer rental.

Hot showers for crews, response teams, camps and events, sourced from local providers. Shower trailers are a smaller fleet than restroom trailers, so the earlier we have your dates, water source and headcount, the better the odds.

Who rents them

Five jobs that end up needing showers.

The trailer is the same. What changes is who's using it, for how long, and what the site already has.

JobWhy showersPlan for
Work under a standard that requires showersAn OSHA standard calls for them, so the count follows the rule below.Shower count by crew and shift, change rooms, towels and soap.
Remote crews and work campsNo hotel within reach, or long shifts in heat and dust.Tanks, a generator and a pump-out schedule.
Storm, flood and fire responseCrews and residents without running water.Fast dates, and no hookups to count on.
Festivals, camps and racesMulti-day crowds who stay on site.Peak morning use and more frequent service.

When OSHA requires showers

One shower for every 10 people of each sex, per shift.

OSHA's construction sanitation rule doesn't require showers on every jobsite. It sets the count when another standard requires employees to shower, and the general industry rule is worded the same way.1

The count is per sex and per shift, and any fraction rounds up. A shift of 18 men and 4 women needs three showers, not two: two for the men and one for the women.

  • CountOne shower per 10 employees, or fraction of 10, of each sex required to shower during the same shift.
  • WaterHot and cold water feeding a common discharge line.
  • SuppliesBody soap or other cleansing agent, and an individual clean towel for each person.
  • Change roomsWhen a standard requires protective clothing because of toxic contamination, change rooms with separate storage for street clothes and protective clothing.

How fast will the waste tank fill?

Every gallon that comes out of a showerhead ends up in the waste tank. Enter your crew and the trailer's tank sizes from the quote, and this works out the gallons a day, how long the tanks last and how many showers OSHA would call for.

Showerhead flow

The 385 gallon default is one manufacturer's three-stall shower trailer. Use the tank sizes on your quote. A combo trailer's toilets and sinks drain into the same tank, so it fills sooner.

Schedule the pump-out before the waste tank lasts out, not after. The OSHA count applies only when a standard requires these people to shower on the same shift.

Why flow rate matters

The showerhead decides how often the truck comes back.

Federal rules cap showerheads at 2.5 gallons a minute. WaterSense labeled heads use no more than 2.0.23 On a trailer with a fixed waste tank, that gap is about a quarter more showers between pump-outs.

Showers per tank is the tank divided by gallons a shower, rounded down. Tank size is one manufacturer's three-stall spec.4

What the site needs

Water in, water out, power and propane.

Two manufacturer spec sheets for three-stall units show what a provider will ask about. Your provider's trailer may differ, so the quote is what counts.4

Cold weather. Ask whether the trailer has winter heat and how lines are protected overnight. Spec sheets list it as an upgrade on some units.

Questions

Questions about shower trailers.

Does OSHA require showers on a construction site?

Not on every site. 29 CFR 1926.51(f)(4) applies when another standard requires employees to shower, and then calls for one shower per 10 employees of each sex on the same shift.

How many showers do I need for my crew?

When OSHA requires showers, divide the men on the shift by 10 and round up, then do the same for the women, and add the two. Otherwise size by how many people shower in the busiest hour.

Does a shower trailer need water and power hookups?

It needs fresh water from a hose or an onboard tank, power from an outlet or a generator, and propane for the water heater on many units. Ask the provider for the exact cord or circuit.

How long does a shower trailer's waste tank last?

Divide the tank by gallons a day. A 385 gallon tank takes about 24 eight-minute showers at 2.0 gallons a minute before it needs a pump-out.

Can I get a trailer with restrooms and showers together?

Yes, combo trailers have a toilet, sink and shower in each station. Toilets and sinks drain into the same waste tank, so service comes sooner.
