What is a portable sink station?
A portable sink station is a self-contained unit with its own fresh water tank, a gray water tank to catch the runoff, and a pump that gets water to the tap without any plumbing hookup. Some units heat the water, which matters if you are asking about a hot water portable sink for a food vendor or a crew washing up in cold weather. The fresh tank feeds the faucet, the gray tank holds what goes down the drain, and you dump the gray tank when it is full. That is the whole system. No sewer line, no water main, just two tanks and a pump. For construction sites, OSHA 1926.51(a)(1) requires an adequate supply of potable water at the place of employment, and a portable sink with a sealed fresh tank satisfies that without trenching a line. If your crew is also using porta john rental units, pairing a sink nearby keeps the whole setup compliant and easier to service on the same visit.
Why do I need a portable sink for hair washing?
Campers and crews washing hair need more water flow and a bigger gray tank than someone just rinsing hands, and that changes which unit fits the job. A basin sized for handwashing empties fast when someone tips their head back under the tap, so we size the tank to the group and the use. This comes up a lot with camping porta potty rentals near river access points, where a sink and a toilet get delivered together. If you are running a base camp for a work crew or a weekend event, ask us about a portable sink and water tank pairing sized for wash-up volume, not just handwash counts. We deliver these across Conway and into nearby towns; Mayflower sits about 10.9 miles south and Menifee about 11.0 miles northwest, both inside our normal delivery run.
How much does a portable sink station cost?
Pricing depends on tank size, whether the unit heats water, and how long you need it. A handwashing station rents in the same general range as a standard portable toilet delivery, and multi-day or weekly rates bring the daily cost down. Ask about our handwashing station rental options and the handwashing requirements page if you are trying to hit a specific ratio for a crew or a permitted event.
| Duration | Typical range |
|---|---|
| Day | $100 - $175 |
| Week | $130 - $500 |
| Month | $125 - $325 |
These bands reflect standard portable toilet and sink station rentals we track across the market; a heated or multi-basin unit runs toward the higher end. Delivery is a separate line, and delivery fees generally land between $100 and $500 depending on distance and the size of the order. If you are comparing costs across services, our porta potty rental cost page and porta potty rental per day page break down the same pricing logic for toilets, which helps if you are ordering both.
Do portable sinks need a permit in Conway?
Placement in a public right of way, a sidewalk, or a street lane needs confirming with the City of Conway before we drop a unit there. On private property, job sites, or event grounds you control, there is no separate step beyond scheduling delivery. If your event is on public land or closes a street, check with the city first; our porta potty permit requirements page covers the general process, though the rule differs by location and we always tell customers to confirm directly rather than guess. For construction sites, OSHA 1926.51(c) sets toilet facility ratios by crew size, and pairing a portable sink nearby is standard practice even though the sink itself isn't part of that specific ratio. Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand-drying device, and hand sanitizer alone does not meet that standard, so we stock soap dispensers on every sink unit we deliver.
Anyone running a job that involves paint, coatings, herbicides, or insecticides should know OSHA 1926.51(f)(1) specifically requires washing facilities for that kind of contaminant exposure, separate from general sanitation needs. That is a common reason contractors add a sink station even when they already have toilets on-site. For agricultural crews, OSHA 1928.110 sets a field sanitation standard of one facility per 20 hand-labor employees within a quarter mile walk, which applies to farms near Conway using portable sinks and toilets together; see our farm and agricultural restrooms page for that setup. If you're scoping a bigger job, construction site services and how many porta potties do i need both help you figure out counts before you call.
How often does the gray tank need to be dumped?
It depends on use, but a sink running steady for a work crew typically needs a dump every few days on a multi-day rental. We handle that as part of scheduled service, similar to how we service standard porta potty rental units on a route. Heavy hair-washing use empties the gray tank faster than simple handwashing.
Can I get hot water in a portable sink?
Yes. Some of our sink stations include a small heater or heated tank, which matters for cold-weather job sites, food service, or anyone washing hair outdoors. Ask when you request a quote so we bring the right unit; not every sink on the lot is heated.
Do I need a separate toilet if I rent a portable sink?
Not always, but most job sites and events pair the two. A sink alone doesn't meet OSHA 1926.51(c) toilet ratios, so if you have workers on-site, you likely need a toilet too. Check portable restroom rental for combined options.
What is the difference between a handwashing station and a full sink station?
A handwashing station is usually a smaller basin built for quick hand rinsing, while a full sink station carries a larger tank and stronger pump built for washing hair, dishes, or heavier use. Both need soap and towels under 29 CFR 1910.141(d)(2).
Will a portable sink work for a wedding or outdoor event?
Yes, and it pairs well with wedding restroom rental or event restroom rental setups. Guests appreciate a sink near the restroom trailer or portable toilets, especially for outdoor venues without running water nearby in Conway.
