What is a portable sink rental?
It's a self-contained handwashing unit: a fresh water tank, a pump, a basin, and a gray water tank underneath to catch what drains out. No hose bib required, no hookup to the building. Some units in our fleet run hot water, which matters more than people expect once fall mornings in Spring Valley turn cold. Crews use them on job sites, caterers use them at events, and a fair number of campers grab one for a weekend because a portable sink for hair washing beats a cold creek every time. Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand drying device, and hand sanitizer alone does not satisfy that. That's the standard behind why these units come stocked the way they do. If you're already renting a portable restroom rental or a standard porta potty rental, pairing it with a sink station rounds out the sanitation package without a separate plumbing call. Some customers ask if it's basically a hand sanitizer station rental with extra steps. It's not. Sanitizer is a supplement, not a substitute, and a proper handwashing station rental with running water and soap is what the requirement is actually built around.
How much water does a portable sink hold?
Fresh water tanks run close to 60 gallons on most units we place, paired with a gray water tank of similar capacity to hold the runoff. That's enough for a work crew across a shift without a mid-day refill, though high-traffic events may need a tank swap. Sizing right matters as much for sinks as it does for toilets. Our how many porta potties do i need guide walks through headcount math that applies just as well to sink stations. For construction sites, OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and a portable sink with a full tank satisfies that without running a line from the trailer. If your crew works with anything that leaves residue behind, the standard shifts: OSHA 1926.51(f)(1) requires washing facilities specifically where workers apply paints, coatings, herbicides or insecticides. That's a narrower rule than general hygiene, but it comes up constantly on renovation and landscaping jobs across Spring Valley.
Can I rent a portable sink for camping or an event?
Yes, and it's one of the more popular reasons people call. A camping portable sink setup gives you a place to wash hands, rinse produce, or do actual portable sink hair washing without breaking camp to find a spigot. For weddings and larger gatherings, we usually pair sink stations with a wedding restroom rental or a full event restroom rental package so guests aren't hunting between two setups. Festival organizers do the same thing at scale; check the festival restroom rental page for how that's typically laid out. Race organizers and marathon crews lean on sink stations near aid stations too, which our marathon restroom rental page covers. Placement matters for accessibility regardless of event size. ADA Standards section 308.2.1 caps a forward reach at 48 inches high and 15 inches low, and section 309.4 requires operable parts usable with one hand and no more than 5 pounds of force, both of which shape how accessible sink units get built and positioned. Our ada accessible porta potty page covers the parallel requirement for toilet units.
Do portable sinks need a water tank refill?
Yes, and how often depends on use. A crew of ten running hand washes all day will draw down a 60 gallon fresh tank faster than a quiet camping weekend will. We handle refills as part of scheduled service, similar to how we manage tank swaps on standard porta potty rental units. ANSI/PSAI Z4.3 sets a baseline service interval of once a week for up to 10 users across a 40 hour week, and that same cadence guides how we schedule sink station visits on longer jobs. If a site sits far from our yard, driving distance affects how flexible that schedule can be. Summerlin South sits 6.3 miles northwest of Spring Valley, Enterprise is 10.0 miles south, and Las Vegas is 10.9 miles north, all comfortably inside a standard service loop. Sites further out, like Henderson at 21.4 miles southeast, still get served, just with a bit more lead time built into scheduling. For jobs that combine sinks with dumpsters or fencing, check construction site services for how we bundle a full site setup.

How much does a portable sink rental cost?
Delivery typically runs $100 to $150 for a single day, with weekly delivery often landing lower per trip than repeated daily calls. Monthly jobs add a service fee for scheduled refills and cleaning, usually in the $100 to $150 range. For a full cost breakdown across unit types, see porta potty rental cost.
Can I use a portable sink without a bathroom nearby?
Yes. A sink station works as a standalone unit and doesn't need to sit next to a toilet. Plenty of job sites and campsites run one on its own for hand washing and rinsing. Pair it with a porta john rental if you want both covered together.
Does a portable sink need power?
No. Most units run on a pump powered by the water system itself, not electricity. That makes them easy to place anywhere on a site, including spots without a temporary power pole nearby.
Is hot water available on portable sinks?
Some units do offer hot water, and it's worth requesting when you book, especially for cold-weather jobs. Not every unit in a fleet carries this feature, so confirm it at the time of your request a quote call.
How many portable sinks do I need for a job site?
It depends on crew size and how spread out the site is. A single sink station covers a small crew fine, but larger sites often need more than one placed at different work zones. Our porta potty placement guide covers the same spacing logic that applies to sinks.
