How Many Showers Does a New Jersey Crew Need? OSHA, PEOSH, and Stall Counts
Which agency covers your crew in New Jersey, the federal shower and toilet ratios, and the trailer sizes that match.
Key points
- Private employers in New Jersey fall under federal OSHA; state and local government workers fall under NJ PEOSH.
- Where a standard requires showers, plan one per 10 employees of each sex on the same shift.
- Construction sites need 1 toilet for up to 20 workers, then 1 seat and 1 urinal per 40.
The first question on any New Jersey shower quote is how many stalls. The answer starts with who your workers are, because the state splits job-safety oversight between two agencies.
Federal OSHA or NJ PEOSH?
New Jersey runs an OSHA-approved State Plan that is public-sector only. According to OSHA's New Jersey State Plan page, it covers all state and local government workers, while federal OSHA keeps authority over private-sector employers in the state. The NJ Department of Labor describes PEOSH the same way: it covers state, county, and local government workers, including affiliated volunteer fire, rescue, medical, and law enforcement personnel, but not federal employees.
- A general contractor, refinery, or warehouse crew: federal OSHA.
- A municipal public works yard, a county road crew, or a state agency site: NJ PEOSH.
The federal ratios
- Showers, where a standard requires them: “One shower shall be provided for each 10 employees of each sex, or numerical fraction thereof, who are required to shower during the same shift” (29 CFR 1910.141(d)(3)(ii)), with hot and cold water, soap, and individual clean towels.
- Construction toilets: 1 toilet for 20 or fewer workers; 1 toilet seat and 1 urinal per 40 workers for 20 or more; 1 per 50 for 200 or more (29 CFR 1926.51, Table D-1).
From ratio to trailer
Count each sex separately and round up: 23 men and 8 women on one shift need three showers for the men and one for the women. Then pick the unit:
- Up to 3 stalls: the 13ft Luxury Shower-Restroom Combination Trailer (3 Individual Stalls) (starting from $2,495 / month), shower and toilet in each stall.
- 5 stalls: the 20ft Shower Container (5 Individual Stalls) (starting from $3,995 / month), showers only, so pair it with a restroom trailer.
- 6 to 8 stalls: the 22ft Luxury Shower-Restroom Combination Trailer (6 Individual Stalls) (starting from $4,995 / month) or the 30ft Luxury Shower-Restroom Combination Trailer (8 Individual Stalls) (starting from $3,995 / month).
- 10 stalls: the 30ft Luxury Shower-Restroom Combination Trailer (10 Individual Stalls), or two units side by side.
These are planning figures, not legal advice. The standard that applies to your work, and your local health officer, set the final count. Send us the headcount by shift and we size it in the quote.
