What Is a Portable Sink Rental?
A portable sink station is a self-contained unit with its own fresh water supply, a soap dispenser, and a wastewater holding tank underneath. No hookup to a building is needed. That is the whole point. Some crews call it a portable sink and water tank combo, others just call it the wash station by the porta potty rental row. Either way it works the same: pump the foot pedal, water comes out of the tap, and the gray water drains into the tank below instead of the ground. Chino contractors running paint crews or applying coatings need this covered under OSHA 1926.51(f)(1), which requires washing facilities where employees apply paints, coatings, herbicides or insecticides. That is a different trigger than general jobsite sanitation, which falls under OSHA 1926.51(c)(1) for toilet counts. Soap and a hand drying device are required by 29 CFR 1910.141(d)(2). Hand sanitizer alone does not satisfy that rule, so do not swap a hand sanitizer station rental in for a real sink where washing is mandated. Pair the sink with a portable toilet rental or a full portable restroom rental setup and you have covered both requirements at once.
How Much Does a Portable Sink Rental Cost in Chino?
Pricing depends on how long you need it and whether it is a bare-bones unit or something closer to a hair-washing station with hot water. Compare it against our full portable sink rental guide and the broader portable restroom rental options before booking.
| unit | day | week | month |
|---|---|---|---|
| standard sink station | 100-350 | 130-500 | 125-325 |
| delivery fee | 100-500 | 50-150 | 120-420 |
| service fee | 100-300 | 30-220 | 100-300 |
Weekend rates for short events run separately from the day/week/month bands above, generally landing between the standard weekend range and the deluxe weekend range depending on the unit. A weekend wedding at a Chino venue might rent a single sink station alongside a wedding restroom rental trailer instead of a bare porta potty. For multi-day builds, check the porta potty rental cost page for how sink rentals bundle with toilet counts, and the porta potty rental per day breakdown if you only need one day.
Can You Wash Hair in a Portable Sink?
Yes, with the right unit. A basic hand-wash station is built for hands and forearms, not a reclined hair wash. If you need a portable sink to wash hair, ask specifically for a hot water portable sink or a deluxe unit built with a deeper basin. Camping groups and film crews are the two customers who ask for this most in Chino. A camping portable sink for a group trip usually just needs the fresh water tank topped off before departure since there is no hookup at the campsite. A film set restroom rental job, on the other hand, often pairs a hair-wash sink with a full deluxe flushable porta potty or a luxury restroom trailer for cast comfort between takes. Ask about hot water portable sink upgrades when you book, since not every unit on the lot carries a heater, and the deluxe day rate runs well above the standard band shown in the table.
Where Do Portable Sink Stations Get Placed on a Site?
They go wherever people need to wash before eating, after handling contaminants, or before entering a food or medical area. On a construction site that usually means next to the break area and near any temporary fence rental entry point, not tucked behind the roll-off dumpster rental. ADA Standards section 302.1 requires the ground surface under and around the unit to be stable, firm and slip resistant, which matters on a dirt lot in Chino after rain. Reach range matters too: ADA Standards section 308.2.1 sets the unobstructed forward reach at 48 inches maximum and 15 inches minimum, and operable parts like the soap pump need to work with one hand and no more than 5 pounds of force under section 309.4. If you are placing a station in or near the public right of way in Chino, that placement needs confirming with the city; we are not naming a specific rule here because it varies by permit and by street. Our porta potty permit requirements page and our porta potty placement guide walk through the general placement logic that applies to sinks too. For farm crews, OSHA 1928.110 requires potable water, toilets and handwashing within a quarter mile walk of hand-labor employees, which is worth checking against our farm and agricultural restrooms page if you run seasonal labor near Chino or out toward Eastvale, 5.9 miles east.
Do Portable Sink Stations Need Their Own Water Tank?
Yes. Every portable sink and water tank combo is self-contained, holding fresh water on one side and gray water on the other, so there is no plumbing tie-in needed at all. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and the sink's onboard tank is what satisfies that on a site with no water line. Tank size varies by unit, running smaller than the 60 to 70 gallon holding tank found on a standard portable toilet, so a high-traffic event in Chino may need 2 or 3 stations serviced on the same route as your event restroom rental units rather than one oversized tank.
How many portable sink stations do I need for a crew of 30?
One station generally covers up to 20 workers before a second is added, following the same per-worker logic used for toilet counts under OSHA 1926.51(c)(1). A 30-person Chino crew should plan for 2 stations, especially if painting or coating work triggers the washing requirement under 1926.51(f)(1).
Does a portable sink rental include hot water?
Not by default. Standard hand-wash stations run cold fresh water from an onboard tank. If you need hot water for hair washing or food service prep, ask for the heated or deluxe unit specifically, since it is a separate line from the base sink station.
Can I rent just a portable sink without a toilet?
Yes, sinks rent on their own. Many Chino customers pair one anyway to cover both OSHA 1926.51(c)(1) toilet ratios and the washing requirement, but a standalone sink works fine for a hair-wash tent, a food booth, or a camping trip.
How often does a portable sink get serviced?
The baseline interval under ANSI/PSAI Z4.3 is one visit per week for moderate use over a standard work week. Heavier events, like a multi-day festival, need more frequent visits, similar to the schedule we run for festival restroom rental jobs.
Is a portable sink station ADA accessible?
It depends on the unit and setup. Reach ranges under ADA 308.2.1 and one-hand operable parts under ADA 309.4 apply to accessible units. Ask for an ADA-compliant station specifically, similar to how you would request our ADA accessible porta potty line.
