How does a portable sink station work?
A portable sink station holds two tanks: fresh water on one side, gray water catch on the other. Step on the foot pump or pull the hand lever and water flows through a small faucet, same as a kitchen sink but with no drain line to the street. Edison Porta Pros stocks units with soap dispensers and paper towel holders built in, which matters because 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device, not just a squirt of sanitizer. If you only need sanitizer for a small crew, that is a different product, covered on our hand sanitizer station rental page. For a full comparison of what counts as adequate washing versus a quick sanitizer fix, see handwashing station requirements. Most stations we place in Edison pair naturally with a standard porta potty rental or a deluxe flushable porta potty nearby, since crews want both in the same spot.
Can I get a portable sink with hot water?
Yes, hot water portable sink units are available, and they matter most for food service, catering and any crew washing up after messy work. A hot water portable sink for hair washing or general cleanup usually pairs a small heating element with the same tank setup as a cold water sink, run off a generator or a nearby temporary power pole. If your crew is applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities for exactly that kind of contaminant exposure, and hot water makes that washing far more effective than cold. We deliver these across Edison and into Metuchen, 4.6 miles north, and Perth Amboy, 6.1 miles east, on the same trucks that handle our restroom trailer rental routes.
Why would a campsite need a portable sink?
Because a camping portable sink solves the two things a campsite lacks: running water and a place to wash hands or dishes without walking to a spigot. A portable sink to wash hair works the same way, just with more tank capacity and a basin deep enough to lean into. Edison Porta Pros builds these into weekend packages for group camping, and they show up often alongside our event restroom rental and festival restroom rental setups, since organizers want hand washing near the food tent and the toilets both. A portable sink and water tank combo can run for days between refills depending on group size, and we size the tank to the headcount before delivery, the same way we size toilet counts against OSHA 1926.51(c)(1) for job sites.
What size water tank does a portable sink need?
Tank size depends on how many people are washing and how often. A small crew of 10 or fewer, working a standard 40 hour week, lines up with the ANSI/PSAI Z4.3 baseline service interval of one visit per week, which is the same interval Edison Porta Pros uses to plan refills on portable sink water tanks. Bigger crews or busy food booths need a larger tank or more frequent service. We walk through the same sizing math on our how many porta potties do i need guide, since sink and toilet counts often scale together on a job site. For agricultural operations, OSHA 1928.110 sets a separate standard: field sanitation requires potable water, toilets and handwashing for hand-labor employees, at one facility per 20 employees, within a quarter mile walk, and our farm and agricultural restrooms page covers that setup in more detail.

Prices above reflect standard portable toilet units for reference; portable sink rentals are typically bundled with a toilet or trailer order in Edison, and we quote sink pricing directly once we know tank size and hot water needs. For dedicated cost breakdowns, see porta potty rental cost and monthly porta potty rental.
Construction sites in Edison need to think about sink placement the same way they think about toilet placement. ADA Standards section 403.5.1 calls for a 36 inch clear route to any accessible unit, and section 404.2.3 sets a 32 inch minimum door opening, both worth checking against our ADA accessible porta potty page if the site also needs an ADA unit. We handle full site layouts through construction site services, including temporary fence rental and light tower rental when a job runs into the evening.
How much does a portable sink rental cost in Edison?
Cost depends on tank size, hot water, and how long you need it. Most sink rentals get bundled with a toilet or trailer order rather than priced alone. Call or use request a quote for an exact number based on your crew size and site.
Do portable sinks need a water hookup?
No. A portable sink runs entirely on its own fresh water tank and gray water catch tank, which is the whole point. No plumbing, no drain line, no spigot required on site.
How often does the water tank need refilling?
It depends on headcount and use. A crew of 10 or fewer over a standard work week lines up with the ANSI/PSAI Z4.3 weekly service baseline. Heavier use, like a food booth, needs more frequent refills.
Can a portable sink handle hot water for hair washing?
Yes, hot water units exist specifically for that. They use a small heating element built into the tank system. Ask for a hot water portable sink when you request your quote.
Do I need a permit to place a portable sink in Edison?
Placement in the public right of way needs confirming with the city. See our porta potty permit requirements page for what to check before delivery day.
