What Is A Portable Sink Rental?
A portable sink is a self-contained station: fresh water tank, a pump, a basin, and a gray water tank to catch what drains out. No plumbing hookup needed. That's the whole point. Crews on a construction lot in Paramount use them next to a standard porta potty rental, and caterers use them for food prep away from a kitchen, sometimes alongside a deluxe flushable porta potty for staff. Some units run cold water only. Others heat it, which matters if you're washing hair or degreasing dishes. A hot water portable sink station usually pairs a small tank heater with the same foot pump or hand lever setup. If you're stocking a job site instead of a kitchen tent, pair the sink with a handwashing station rental so you have both a wash basin and a dedicated soap and towel setup, since 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at washing facilities, not just water. Sanitizer gel alone does not satisfy that. For agricultural crews doing hand labor, OSHA 1928.110 sets a different bar: one facility per 20 employees, reachable within a quarter mile walk, which is worth checking against a farm and agricultural restrooms setup.
How Much Water Does A Portable Sink Hold?
Tank sizes vary by model, and the right one depends on headcount and how often we can service it. A camping portable sink for a family trip needs less water than a portable sink for hair washing at a salon pop-up, a wedding restroom rental setup, or a film set. Paramount Porta Pros sizes the water tank to the job, then schedules refills so the unit never runs dry mid-shift. If you're running a multi-day event, ask about pairing the sink with a portable restroom rental order so both services get serviced on the same route. For construction sites, general sanitation facility counts fall under OSHA 1926.51(c): one toilet for 20 or fewer workers, scaling up from there, and a portable sink station often sits right beside that toilet bank so crews wash before they eat or drive home. Film sets in particular tend to need a wash station near catering, not just near the restrooms, and a film set restroom rental order usually includes both, the same way a festival restroom rental package bundles sinks with the toilet bank.
What Does Portable Sink Rental Cost?
Pricing depends more on hookup and heating than on the sink itself. A basic cold water unit rents cheaper than a hot water portable sink with its own heater and larger tank. Delivery adds a flat fee on top, and that fee scales with distance and how many units you're placing on one trip.
| item | day | week | month |
|---|---|---|---|
| delivery fee | 100 - 500 | 50 - 150 | 120 - 420 |
| service fee | 100 - 300 | 30 - 220 | 100 - 300 |
Ranges above cover delivery and service call fees only, since sink-specific pricing wasn't in our measured set; ask Paramount Porta Pros for a sink quote tied to your exact tank size and hookup. If you're comparing against toilet rental costs to plan a full site budget, the porta potty rental cost page and the porta potty rental per day breakdown both use the same delivery and service fee structure. Longer jobs do better on a monthly porta potty rental plan, and the same logic applies to sink stations billed alongside a porta john rental order.
Where Should A Portable Sink Go On Site?
Placement matters more than people think. A sink needs level ground, and ADA Standards section 302.1 calls for stable, firm, slip-resistant surfaces wherever an accessible route runs, which includes the path to a wash station if you're pairing it with an ADA accessible porta potty. Keep at least 36 inches of clear route per ADA Standards section 403.5.1, and if the sink sits behind a fence line or barrier, make sure the gap still clears that width. Our porta potty placement guide covers ground clearance and access in more depth, and the how many porta potties do I need guide helps figure out headcount before you place anything. In Paramount, sinks paired with dumpsters or fencing on a construction lot should sit close to the toilet bank, not scattered across the site, so crews actually use them between tasks. If the job also needs temporary fence rental around the perimeter, keep the sink inside the fenced work zone so it doesn't wander off with foot traffic from the street, and a nearby roll-off dumpster rental should sit on the opposite side to keep traffic flowing.
Delivery routes into Paramount cover the nearby cities too. Crews working sites near Bell Gardens, about 6.5 miles north, or Cerritos, roughly 8.1 miles east, can get the same sink and tank setup on the same delivery run. Bell and Cudahy sit even closer, both within roughly 7 miles, so multi-site contractors often stack orders across those towns in one trip. Check service areas for the full coverage map, browse our porta potty rental options for the city itself, or start with a request a quote if you already know your headcount and dates.
Can a portable sink be used for washing hair?
Yes, with a hot water unit. Cold water works for handwashing, but hair washing goes faster and feels better with heat. Ask for a heated tank model when you book, since not every portable sink station includes one by default.
Do portable sink rentals need a water hookup?
No. They run on a self-contained tank, refilled on a service schedule. That's what makes them useful at camping porta potty sites, home renovation porta potty jobs, and remote construction lots where there's no spigot nearby.
How often does the water tank need refilling?
Depends on headcount and tank size. High-traffic sites need more frequent refills. Paramount Porta Pros sets the service interval when we deliver, based on your crew size and hours on site.
Can I rent a portable sink without a portable toilet?
Yes, they rent separately. Caterers and food trucks often need just the sink. Construction and event sites usually order both together, since OSHA 1926.51(c) sanitation counts assume toilets and wash stations sit near each other, a pairing our construction site services page walks through in full.
Is a portable sink the same as a handwashing station?
Close, but not identical. A handwashing station usually emphasizes soap and towel dispensing per 29 CFR 1910.141(d)(2). A portable sink adds a full basin and larger tank, better suited to hair washing or food prep tasks.
