What is a portable sink station?
A portable sink station is a freestanding basin with its own water supply. Fresh water sits in a tank up top, gravity or a foot pump pushes it through the faucet, and a second tank below catches the gray water. There's no hose bib or drain line required, which is why they show up at construction sites, farm stands, and weekend markets across Mount Vernon. Some units heat the water; most run cold unless you specifically order a hot water portable sink for food service or a job where workers need to wash off paint, coatings, or other contaminants under OSHA 1926.51(f)(1). Soap and a drying method have to be present too. Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand-drying device. Hand sanitizer alone doesn't satisfy that rule. If you're stocking a jobsite bathroom setup, pair the sink with a handwashing station rental or a portable sink rental unit sized for crew count, and check the handwashing station requirements page before you order.
How much water does a portable sink hold?
Tank sizes vary by model, and matching tank size to headcount is the main sizing question we get. A crew of ten using a sink for hand-washing all day pulls through a tank faster than a wedding where guests rinse hands between courses. Bigger portable sink water tanks mean fewer refills, but they also mean a heavier unit that takes more room to place. If you're running one sink alongside multiple porta potty rental units for a full crew, our team maps water tank size against crew size and shift length when we quote the job, the same way we do for monthly porta potty rental accounts. For events, check the event restroom rental page, since sink placement there usually sits next to the restroom bank, not off on its own.
Can I use a portable sink to wash hair?
Yes, and it's one of the more common asks we get outside job sites. A portable sink to wash hair works for camping trips, disaster relief staging, film sets, and shelters where a real shower trailer isn't in the budget or the timeline. The basin depth and faucet height matter more here than tank size. If hair washing is the main use, ask us about basin dimensions before you book, because not every portable sink for hair is built the same way. For a full-body option instead of just a sink, look at the shower trailer rental or restroom trailer rental pages, both of which run hot water and give people more than a basin to work with.
Where do portable sinks get used most?
Job sites lead the list, followed by farm stands, food trucks, and short-term events. On a construction site, OSHA 1926.51(c) sets the toilet-to-worker ratio, but the washing requirement sits separately under 1926.51(f)(1) once paints, coatings, herbicides, or insecticides are part of the job. That's the trigger, not general dirt or dust. Farms fall under a different standard: OSHA 1928.110 calls for one field sanitation facility per 20 hand-labor employees, reachable within a quarter mile. A camping portable sink shows up at group campsites and disaster staging areas where there's no running water at all. In Mount Vernon, we deliver sinks alongside construction site services packages, home renovation porta potty setups, and standalone rentals for markets and pop-up events. Crews working near Pelham, about 2.0 miles east, and Mamaroneck, 7.4 miles east, often add a sink station when the temporary fence rental or light tower rental order goes out too.
Portable sink and porta potty pricing compared
| item | day | week | month |
|---|---|---|---|
| standard porta potty | $100 to $350 | $130 to $500 | $125 to $325 |
| ADA accessible unit | $200 to $400 | $185 to $240 | not listed |
| delivery fee | $100 to $500 | $100 to $150 | $120 to $420 |
Portable sink pricing isn't in our measured dataset yet, so we quote it directly based on tank size and rental length rather than publishing a range here. A standard unit for comparison sits at about 44 by 48 inches on the ground and stands roughly 92 inches tall, useful if you're planning where the sink goes next to it. Check porta potty rental cost or porta potty rental per day for the full breakdown on toilets, and request a quote for the sink itself.
How often does a portable sink need servicing?
It depends on use, but the baseline industry interval under ANSI/PSAI Z4.3 is one service visit per week for up to 10 users over a 40-hour week. Heavy hand-washing use or hair washing burns through fresh water faster, so we often service sinks more often than that baseline on active job sites.
Does a portable sink need its own delivery fee?
Usually it rides along with an existing delivery when it's ordered with toilets or a fence package. Standalone sink deliveries fall into the same delivery fee band as other equipment, generally $100 to $500 for a single day depending on distance and access.
Can a portable sink run hot water?
Some units do. A hot water portable sink is built with a small heating element or insulated tank and costs more to run than a cold-water model. Food vendors and job sites doing paint or coating work under 1926.51(f)(1) are the most common reason we get this request.
Is a portable sink ADA accessible?
Not automatically. Height and reach matter for accessibility, and ADA Standards 308.2.1 caps forward reach at 48 inches high and 15 inches low. If you need an accessible unit specifically, ask when booking, and check our ADA accessible porta potty page for the related toilet standard.
What is the difference between a portable sink and a handwashing station?
Not much in practice. Both hold fresh water above and gray water below. "Handwashing station" usually implies a simpler basin built for quick hand rinses, while "portable sink" can mean a larger unit meant for dishes, food prep, or hair washing. Ask us which fits your job before ordering.
