What Is a Portable Sink Station?
A portable sink station is a self-contained unit: a fresh water tank feeds the faucet, a gray water tank catches what drains out, and the whole thing sits on legs or wheels so it can go anywhere. No sewer line, no water main, nothing buried. Some units run on a foot pump, some run on a small 12-volt pump wired to a battery, and some come with hot water for a real wash instead of a rinse. For hand-labor crews, OSHA 1928.110 sets a baseline of one facility per 20 employees, within a quarter mile walk, and a sink station satisfies that alongside a portable toilet rental. For general job sites, 29 CFR 1910.141(d)(2) requires soap and towels or a hand dryer at any washing facility; hand sanitizer alone does not meet that standard. Maple Grove Porta Pros pairs handwashing station rental with standard porta potty rental or a portable restroom rental order so crews get both in one delivery. If your crew is doing paint, coatings, herbicide, or insecticide work, OSHA 1926.51(f)(1) requires washing facilities for that specific exposure, separate from the general hygiene rule.
Can I Wash My Hair in a Portable Sink?
Yes, with the right unit. A standard sink station handles hands and dishes fine, but washing hair needs more water pressure and usually a hose attachment or a taller basin so you're not bent double over a 30-inch sink. Campers and event vendors asking about a portable sink to wash hair usually want a hot water portable sink with a spray head, not the basic foot-pump model. We stock both. If you're setting up for a multi-day event or a camping porta potty package, ask for the upgraded tank size so hair washing doesn't drain the unit by midday. A deluxe flushable porta potty paired with a hot water sink station is the combination most wedding and event clients in Maple Grove end up choosing over the basic setup.
How Much Water Do Portable Sink Stations Hold?
Tank sizes vary by model, but the water supply is the whole story with these units: no tank, no water. A portable sink and water tank setup typically carries separate fresh and gray tanks so the unit doesn't need dumping every few hours. For comparison, a standard portable toilet on our lot runs a 60 to 70 gallon holding tank, and sink station tanks are sized to match that kind of multi-day duty cycle. ANSI/PSAI Z4.3 sets a baseline service interval of once per week for up to 10 users over a 40-hour week, and we schedule sink station refills on the same rhythm as our porta john rental service routes. Bigger crews or longer events need more frequent top-offs. If you're not sure how many stations your headcount needs, the guide on how many porta potties do I need covers the ratio math and applies the same logic to sink placement.
Where Should a Portable Sink Station Go on Site?
Put it next to the toilets, not across the lot. Workers won't walk 40 yards out of their way to wash up, and neither will your guests. For accessible setups, ADA Standards section 304.3.1 calls for a 60 inch turning circle at the fixture, and section 308.2.1 caps the forward reach at 48 inches high, 15 inches low, so an ADA accessible porta potty station needs a sink at a compatible height nearby. Ground stability matters too: ADA Standards section 302.1 requires the surface under the unit to be stable, firm, and slip resistant, which rules out loose gravel or soft turf for wheelchair users. Our porta potty placement guide and dedicated guide at porta potty placement guide cover the same ground rules for full restroom setups. For jobsites already running temporary fence rental or a light tower rental, keep the sink inside the lit, fenced perimeter so it gets used after dark.
Pricing
| unit | day | week | month |
|---|---|---|---|
| standard porta potty | $100-$350 | $130-$500 | $125-$325 |
| ADA unit | $200-$400 | $185-$240 | - |
| delivery fee | $100-$500 | $100-$150 | $120-$420 |
Sink stations typically get quoted alongside a toilet order rather than standalone, since most sites need both. A request a quote covering your full headcount and event length gets you an accurate number faster than pricing the sink alone. If you're budgeting a bigger job, the breakdowns on porta potty rental cost and porta potty rental per day walk through what drives the range.
Frequently asked questions
Do portable sink stations need a water hookup?
No. Every unit carries its own fresh water tank and a separate gray water tank for drainage, so it works anywhere you can park it. That's the whole point of a portable sink rental over a plumbed fixture. Battery-powered pump models need nothing but a flat spot.
How often does a portable sink get serviced?
ANSI/PSAI Z4.3 sets a weekly baseline for up to 10 users over a 40-hour week, and Maple Grove Porta Pros follows that same schedule for sink refills. Higher headcounts or multi-day events need more frequent visits. Ask about your specific setup when you request a quote.
Can a portable sink run hot water?
Yes, hot water portable sink models are available and popular for events and hair washing needs. They cost more than the basic foot-pump unit because of the added heating component. Ask which model fits your job when you call.
Is soap included with a portable sink rental?
Yes. 29 CFR 1910.141(d)(2) requires soap and a towel or drying device at any washing facility, and our units come stocked to meet that standard. Hand sanitizer stations are a separate product; see hand sanitizer station rental if that's what you actually need.
Do I need a sink if I already have hand sanitizer on site?
For most job sites, no, sanitizer alone doesn't satisfy 29 CFR 1910.141(d)(2), which specifically requires soap and towels. Food service, hair washing, and paint or coating work under OSHA 1926.51(f)(1) all need real water. Check handwashing requirements for your specific situation before deciding.
