Portable sink rental in Ontario runs from a single hand wash basin to a full portable sink station with a heated tank, and it pairs with almost every job type Ontario Porta Pros services. A basic unit fits alongside standard porta potty rental for 60 to 70 gallons of fresh water capacity per fill.
A portable sink is a self-contained basin with its own fresh water tank, a pump, and a wastewater holding tank underneath. No hookup needed. That's the whole point for a construction yard in Ontario or a backyard wedding that has no plumbing nearby. Most units run on a foot pump or a small battery pump, and some come with a hot water option for washing hands after a long shift or rinsing dishes at a food booth.
This is different from a handwashing station rental, which is usually a simpler basin built for high-traffic hand cleaning near a bank of toilets. A portable sink station does more. Caterers use them for food prep. Campers use a portable sink for hair washing when they don't want to deal with a shower trailer. Film crews use them on location because a film set restroom rental package often needs a wash station nearby too. If your event also needs toilets, look at event restroom rental or check the broader portable restroom rental options to bundle everything into one delivery.
Under 29 CFR 1910.141(d)(2), washing facilities need soap and a way to dry hands, towels or a hand drying device. Hand sanitizer alone doesn't satisfy that. A portable sink with soap and paper towels covers it; a sanitizer stand by itself does not.
A basic handwashing setup runs close to what a standard porta potty rental costs for the same rental window, since delivery and service logistics are similar. Below is a general reference for related sanitation rentals, since a dedicated portable sink pricing table depends heavily on how many units and what water capacity you need.
| unit | day | week | month |
|---|---|---|---|
| standard toilet | 100-350 | 130-500 | 125-325 |
| deluxe flushable | 85-1200 | 150-290 | - |
| delivery fee | 100-500 | 50-150 | 120-420 |

Because water access is rarely where you need it. A portable sink water tank holds fresh water onsite so crews and guests can wash up without walking to a trailer or a distant spigot. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and a portable sink with its own tank satisfies that need directly at the work area.
For paint crews, roofers using coatings, or anyone applying herbicides or insecticides, OSHA 1926.51(f)(1) specifically requires washing facilities for that contaminant exposure. A hot water portable sink station near the work zone means a painter isn't tracking solvent residue into a truck cab. Pair that with construction site services and a temporary power pole if the unit needs power for a heated tank.
Agricultural operations fall under a different standard. OSHA 1928.110 requires potable water, toilets and handwashing for hand-labor employees, with one facility per 20 workers within a quarter mile walk. That's a common setup for farm and agricultural restrooms work around Ontario, where field crews are spread across acreage far from any fixed plumbing.
Yes, and it's one of the most common uses we see. A portable sink for hair washing works well at campgrounds, disaster relief camps, or long-term construction crews living onsite. The tank holds enough water for several wash cycles before a refill, and a hot water option makes it usable in colder months, something worth checking against our porta potty in winter guide if the rental spans a cold stretch.
Camping groups near Ontario often pair a portable sink with camping porta potty rentals rather than hauling their own water setup. Disaster relief crews do the same, since disaster relief sanitation jobs need fast setup with no fixed utilities. Eastvale sits 6.8 miles south of Ontario and Jurupa Valley is 9.0 miles east, both areas we deliver to on the same routes we run for standard toilet and trailer rentals.
If your event needs full showers instead of a wash basin, a shower trailer rental is the better fit. For anything in between, a portable sink rental with a larger tank splits the difference nicely between a hand wash station and a full shower unit.
It depends on headcount and how the work is spread out. OSHA 1926.51(c)(1) sets toilet ratios by crew size, and washing stations typically scale the same way. A 20-person crew usually does fine with one unit; larger crews spread across a site need more than one station placed near the work.
No. A portable sink carries its own fresh water tank and its own wastewater tank underneath. That's the entire advantage over a fixed sink. You just need clearance for delivery and a flat, stable spot for setup.
That depends on usage and headcount, similar to the weekly service interval used for portable toilets under ANSI/PSAI Z4.3 for standard rentals. Heavy-use kitchens or wash stations may need more frequent refills than a low-traffic hand wash setup.
Some units do. A hot water portable sink station usually needs a small power source, either battery or a connection to a temporary power pole if the job site has one running already for other equipment.
Washing facilities are required under OSHA 1926.51(f)(1) specifically when workers apply paints, coatings, herbicides or insecticides. For general sanitation, 1926.51(c) covers toilet counts. Check our OSHA portable toilet requirements guide for the full breakdown by crew size.
