What Is a Portable Sink Station?
A portable sink station is a self-contained basin with its own fresh water supply and a holding tank underneath to catch the wastewater. No plumbing hookup, no drain line. Some units heat water, which matters if you are running one for hair washing or for a crew that needs more than a cold splash on a January morning. Arlington Heights Porta Pros pairs these with handwashing station rental setups on job sites and can add a portable sink rental unit next to a standard porta potty rental or a deluxe flushable porta potty for a fuller restroom setup. Under 29 CFR 1910.141(d)(2), washing facilities need soap and a towel or hand-drying device, and hand sanitizer alone does not satisfy that. That rule covers general industry workplaces, not construction sites specifically, but it is the standard we build every sink station to meet regardless of the job.
Can You Wash Your Hair in a Portable Sink?
Yes. A hot water portable sink built for hair washing has a basin deep enough to lean back into and a hose or sprayer attachment, and it is a common request for film shoots, salons doing outdoor events, and disaster relief work. If your event is more restroom-driven than sink-driven, pair this with an event restroom rental or a restroom trailer rental so guests have both. Wedding parties near Arlington Heights often ask about a portable sink to wash hair before photos, and we can run one alongside a luxury restroom trailer for that. For film sets specifically, check our film set restroom rental page, since crews frequently need both a hair-washing sink and standard restrooms on the same call sheet.
Why Do Job Sites Need Portable Sink and Water Tank Setups?
Construction crews need washing facilities under OSHA 1926.51(c), which sets toilet ratios by crew size, and a separate provision, OSHA 1926.51(f)(1), that requires washing facilities specifically where workers apply paints, coatings, herbicides or insecticides. If your crew is spraying anything on the job, a portable sink station near the work area is not optional. We deliver these across construction site services calls in Arlington Heights and pair them with a porta john rental or full portable toilet rental package depending on crew size. Farms have their own rule: OSHA 1928.110 requires potable water, toilets and handwashing within a quarter mile walk for hand-labor employees, one facility per 20 workers, which is why our farm and agricultural restrooms page covers sink stations too. Home renovation crews doing paint or exterior coating work should look at home renovation porta potty service and add a sink station to the order.
Where Do Camping Portable Sink Setups Get Used?
Campgrounds, tailgates and remote job sites all use a self-contained camping portable sink because there is no water line to tap into. The unit runs on its own tank, so placement only depends on ground access, not proximity to plumbing. That makes it a fit for camping porta potty setups, county fairgrounds, and golf courses running multi-day tournaments. Check golf tournament restrooms or county fair restrooms if you are staging a larger event with both sinks and restrooms needed across several stations. We deliver into Arlington Heights and to towns nearby, including Mount Prospect 3.7 miles southeast and Palatine 4.6 miles west, so a multi-town event circuit is not a problem.
Portable Sink Pricing
| Duration | Typical Range |
|---|---|
| Daily rental | Priced with delivery, varies by tank size and hot water option |
| Weekly rental | Higher than daily, reflects extended servicing |
| Monthly rental | Highest tier, standard for ongoing job sites |
Delivery fees for a day rental generally run in the $100 to $150 range, with a low end around $100 and a high end near $500 for complex placements. Weekly delivery runs lower per visit, from about $50 to $150, since it is spread over a longer rental.

Placement and Accessibility Notes
If your sink station serves a public event, ADA Standards section 308.2.1 sets a maximum high forward reach of 48 inches, which matters for basin height. ADA Standards section 309.4 requires operable parts, like faucet handles, to work with one hand and no more than 5 pounds of force. If you are also renting portable toilets for the same event, ADA Standards section 213.2 requires at least 5 percent of a cluster of single-user toilets to be accessible, never fewer than one, which is covered in more depth on our ADA accessible porta potty page and our general ADA restroom requirements guide. For questions on where units can legally sit, see porta potty placement guide.
How much water does a portable sink hold?
Most units carry a 5 to 20 gallon fresh water tank with a separate holding tank underneath for wastewater. Larger events or job sites often rent multiple units rather than one oversized tank, since refill and pump-out logistics are simpler with several smaller sinks spread across a site in Arlington Heights.
Do portable sinks need a power hookup?
No. Most run on battery-powered pumps or gravity feed, and hot water models use a small onboard heater. That is what makes them work for camping porta potty sites and remote job locations where there is no outlet nearby.
Can I rent a portable sink for just a weekend?
Yes, short-term rentals are common for weddings, festivals and one-day job site needs. Ask about a weekend rate when requesting a quote, since weekend pricing differs from standard day, week or month billing structures used for longer rentals.
Is a portable sink enough to meet OSHA handwashing rules?
It depends on the work. If your crew applies paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities, and a portable sink station satisfies that. For general toilet and sanitation counts, see OSHA 1926.51(c) instead.
What is the difference between a portable sink and a handwashing station?
They overlap. A handwashing station is usually simpler, foot-pump operated, built for high-traffic quick washing. A portable sink built for hair washing has a deeper basin and often a hose attachment. Compare options on our handwashing station rental page.
