What Is a Portable Sink Station?
A portable sink station is a self-contained basin with its own fresh water supply and its own waste tank underneath, built to work anywhere there's no hookup. Some models heat the water, which matters if crews are washing up after handling anything greasy or if you're running a portable sink hair washing setup at an event. Glendora Porta Pros stocks both foot-pump and battery-pump models, and both hold enough water for a steady stream of users across a workday. These pair well with handwashing station rental service when a jobsite needs multiple points spread across a lot, and they're a common add-on to portable toilet rental packages because inspectors expect a wash station near the restrooms anyway. For construction crews, OSHA 1926.51(a)(1) requires an adequate supply of potable water at the site, and a portable sink and water tank setup is the simplest way to check that box without trenching a water line. Unlike a hand sanitizer station, a real sink with soap and running water is what the general industry standard at 1910.141(d)(2) actually calls for.
How Does a Portable Sink Hair Washing Station Work?
It works like a salon basin, just mobile: a reclining or lean-forward basin, a sprayer fed from the tank, and a drain running to the gray water side. Camping portable sink setups, festival vendor rows and film sets around Glendora all use the same core unit, just configured differently. A hot water portable sink model is worth the upgrade for hair washing specifically, since cold-tank water gets uncomfortable fast for anyone leaning over a basin for more than a minute. We deliver these to film set restroom rental jobs and to wedding restroom rental sites often, usually staged near the restroom trailer so guests or crew aren't walking far between the two. If you're running a stall count for a bigger production, check our 4 stall restroom trailer or 8 stall restroom trailer options, since sink stations get placed right outside those trailer doors more often than not.
Do Portable Sink Stations Need a Water Tank Refill?
Yes, and how often depends on use. A tank that's rated in the 20 to 40 gallon range for the fresh side will need a refill or swap after a busy day of heavy traffic, sooner if it's a portable sink for hair washing where each rinse pulls several gallons at once. We handle refills as part of service on multi-day rentals, same as we service porta john rental units on a route. For agricultural sites, OSHA 1928.110 sets the standard for field sanitation, calling for potable water and handwashing facilities within a quarter mile walk for hand-labor employees, which is why we place sink stations on farm and agricultural restrooms jobs at set intervals rather than clustered in one spot. Construction sites lean on OSHA 1926.51(c) for toilet ratios, but the water supply requirement in 1926.51(a)(1) is the one that actually drives sink placement on those same construction site services jobs.
Where Should a Portable Sink Station Be Placed?
Right next to the toilets or food prep, on stable, level ground, is the short answer. ADA Standards section 302.1 calls for floor and ground surfaces that are stable, firm and slip resistant, and that applies to the pad under a sink station just like it applies to a restroom pad. If you're placing an accessible unit, ADA Standards section 308.2.1 sets the forward reach range at 48 inches maximum and 15 inches minimum, so the basin height on any ADA-configured sink has to sit inside that band. We check placement the same way we do for ADA accessible porta potty orders. Glendora sites with tight access, especially near downtown, sometimes need to confirm curb placement with the city before delivery. If the spot is along a public sidewalk or right of way, that needs confirming with the City of Glendora directly, since we're not the ones who set that rule. For jobs stretching into nearby cities, we've delivered as far as San Dimas, 4.6 miles southeast, and Azusa, 4.9 miles west, without changing the setup.
Portable Sink Pricing
| unit | duration | typical price |
|---|---|---|
| standard porta potty | day | $150 |
| standard porta potty | week | $200 |
| standard porta potty | month | $200 |
| delivery fee | week | $100 |
| service fee | week | $60 |
Sink stations get quoted alongside whichever restroom package they're paired with, since delivery and service fees are usually shared across the order. Check porta potty rental cost or monthly porta potty rental for the full breakdown on the restroom side, and request a quote for a sink-specific number based on your site.
How much water does a portable sink hold?
Most units carry a fresh tank in the 20 to 40 gallon range with a matching gray water tank underneath. Heavy-use events, especially hair washing stations, drain faster and may need a mid-day refill, which we can schedule as part of a multi-day event restroom rental order.
Can I rent a portable sink without a toilet rental?
Yes. Standalone sink stations go out for vendor rows, film sets and hand-labor crews that already have restrooms covered. We still recommend pairing it with a portable restroom rental order when the site doesn't have one, since inspectors expect both together.
Do portable sinks have hot water?
Some models do. A hot water portable sink uses a small heating element or pre-heated tank fill, and it's the right call for hair washing or cold-weather jobs. Ask about it when you request a quote, since not every unit in the fleet is heated.
How many sink stations do I need for my crew?
It depends on headcount and layout, same logic as restroom counts under OSHA 1926.51(c). A rough guide is one station per cluster of toilets. Our how many porta potties do i need page walks through the math for mixed crew sizes.
Are portable sinks required on construction sites?
OSHA 1926.51(a)(1) requires potable water at the site, and 1926.51(f)(1) specifically requires washing facilities where crews apply paints, coatings, herbicides or insecticides. A sink station satisfies both. See osha portable toilet requirements for the full standard.
