What is a portable sink rental?
It's a self-contained unit with a fresh water tank, a foot pump or hand pump, soap, and a wastewater tank underneath to catch what drains out. No hookup to a building, no hose bib required. Port Saint Lucie Porta Pros builds these around a fresh water tank that runs up to 60 gallons, which handles a decent-sized crew before it needs a refill. Some units add a small hot water heater for handwashing in cooler months, though most jobsites run cold water fine since the point is soap contact time, not water temperature. Under 29 CFR 1910.141(d)(2), wash stations need soap and towels or a hand-drying device, not just sanitizer, and our units are built to that standard. Pair one with a handwashing station rental if you need multiple stations spread across a site, or add a portable sink rental alongside your portable restroom rental for a full setup. If you're building out a jobsite from scratch, our construction site services page walks through the full lineup.
Why do jobsites need a portable sink station?
Because a toilet without a sink next to it doesn't meet the intent of general sanitation. OSHA 1926.51(c) sets toilet counts by crew size, and pairing wash stations with those toilets is standard practice on any site inspectors walk through. If your crew is spraying paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) specifically requires washing facilities for that contaminant exposure, separate from the general toilet count. That's a common trigger on renovation and landscaping jobs around Port Saint Lucie, where crews move between properties and can't count on a hose bib being live. A portable sink station also cuts down on cross-contamination during lunch breaks, which matters more on food-adjacent jobs. If you're not sure how many stations your crew size needs, our how many porta potties do I need guide covers ratios, and OSHA portable toilet requirements breaks down the citation in plain language. For agricultural crews, OSHA 1928.110 sets a separate standard: one facility per 20 hand-labor employees, within a quarter mile walk, which applies to a lot of the grove and nursery work east toward Jensen Beach, 11.0 miles away.
Can I use a portable sink for hair washing?
Yes, and it's one of the more common requests we get for events and camping trips. A portable sink for hair works best with a unit that has a hot water option, since cold water and shampoo don't mix well for most people. If hair washing is the main goal, some customers step up to a shower trailer rental instead, especially for multi-day events or disaster relief housing. But for a quick rinse station at a race, a wedding, or a weekend camp, a portable sink to wash hair does the job without the plumbing of a full trailer. We've set these up for wedding restroom rental packages where the bridal party needs a touch-up station, and for camping porta potty setups where guests want more than a wet wipe. Camping portable sink demand also spikes around river access points near North River Shores, 11.2 miles southeast of downtown Port Saint Lucie, where there's no running water for miles.
What does a portable sink rental cost?
Pricing depends on unit type, tank size, and how long you need it. A basic hand-wash station runs less than a full deluxe unit with hot water and a larger reservoir. Below is a general range based on comparable rental categories; ask for a written quote through request a quote since sink-specific units vary by inventory.
| Unit type | Day | Week | Month |
|---|---|---|---|
| Standard wash station | $100 - $350 | $130 - $500 | $125 - $325 |
| Deluxe station w/ hot water | $85 - $1,200 | $150 - $290 | - |
Delivery adds a separate fee, typically $100 to $500 for a single-day drop and pickup, or $50 to $150 if billed weekly. If you're comparing this against a full restroom package, our porta potty rental cost and monthly porta potty rental pages break down bundled pricing. For septic-side facilities, check septic tank pumping cost separately, since that's a different service entirely.
Do portable sink stations need their own water tank?
Yes. Every unit we deliver carries its own fresh water tank and a separate wastewater tank, so it's fully self-contained and doesn't rely on your site having a spigot. Portable sink water tanks on our standard units hold enough for several days of moderate use before a refill run, though heavy-traffic events usually schedule a mid-week top-off. This matters for sites out near Fort Pierce South, 13.0 miles north, or White City, 13.1 miles northeast, where crews often work well outside any municipal water line. If your event pulls a bigger crowd, ask about pairing multiple portable sink stations with our event restroom rental or festival restroom rental packages, both of which scale station counts to headcount. For ADA compliance on any clustered restroom setup, ADA Standards section 213.2 requires at least one accessible unit in the group, and our ADA accessible porta potty page covers that in detail.
Can I rent a portable sink without a toilet?
Yes. Plenty of customers rent a sink alone for a food booth, a car wash fundraiser, or a job site that already has toilets but no wash setup. It attaches to nothing and needs no plumbing hookup.
How often does the water tank need refilling?
Depends on crew size and use. A tank in the 60 gallon range on a 10-person crew often lasts several days between refills; heavier use means more frequent top-offs, which we can schedule with delivery.
Is hot water available on portable sink rentals?
Some units offer a small heater, mainly on deluxe models. If hot water matters for your job, mention it when booking so we send the right unit instead of a cold-only standard model.
Do I need a permit for a portable sink on my property?
Placement in the public right of way needs confirming with the City of Port Saint Lucie before delivery. On private property it's usually straightforward, but check our porta potty permit requirements page first.
Can a portable sink handle handwashing after using pesticides?
Yes, and it should. OSHA 1926.51(f)(1) requires washing facilities specifically after applying herbicides or insecticides, so a station near that work area is a compliance requirement, not just a convenience.
