What comes with a portable sink rental?
A portable sink station is a self-contained unit: fresh water tank, pump, basin, soap dispenser and a gray water tank underneath to catch what goes down the drain. Most units run off a foot pump or a small battery pump, so you don't need power. Some models heat water, which matters if crews are washing up after handling anything greasy or after using temporary fencing posts set in cold ground. For jobsites applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities on site, and a portable sink station satisfies that. General handwashing on a construction site falls under 1926.51(c), the same standard that governs porta john rental counts. Pair a sink with a handwashing station rental or a portable sink rental upgrade if you need more basins per crew. We deliver across Spokane and into Town and Country, 4.6 miles north, without a special trip charge built into the base rate.
How much does a portable sink rental cost in Spokane?
Pricing depends on tank size, hot water, and how long you need it. A basic camping portable sink with a hand pump costs less than a heated multi-basin station built for a food vendor or a construction crew washing off adhesives. Ask about bundling with a dumpster rental cost quote or a porta potty rental cost if you're renting several service types for one job.
| Service | Day | Week | Month |
|---|---|---|---|
| Standard porta potty | $100-$350 | $130-$500 | $125-$325 |
| Delivery fee | $50-$100 | $100-$150 | $120-$420 |
| Service fee | $30-$60 | $100-$300 | $100-$300 |
Portable sink units typically price close to the service fee band above, since they're often added to an existing route rather than delivered alone. A standalone delivery still carries its own delivery fee, same as a portable toilet rental drop-off.
Can a portable sink be used to wash hair?
Yes, but you want the bigger tank. A basic camping portable sink built for handwashing holds too little water and too shallow a basin for hair washing. Look for a portable sink to wash hair that comes with a deeper basin, a hose sprayer attachment, and at least a 10 gallon fresh water tank so you're not refilling every few minutes. These get used at events, disaster relief sites, and by film crews needing a portable sink for hair between takes. If you're staging a film set restroom rental or running disaster relief sanitation, ask us to pair a hair-washing capable sink with a shower trailer rental so people can rinse fully, not just at the sink. For weddings and similar events, a wedding restroom rental package can include a sink station near the restroom trailer entrance, which also helps meet 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device at washing facilities. Hand sanitizer alone does not satisfy that standard, so a real sink with soap matters if you're trying to check that box for a crew or vendor staff.
Do portable sink stations need a water hookup?
No. Every unit we rent carries its own water tank, so nothing has to hook into a building line or hydrant. That's the whole point of a portable sink and water tank setup: it goes anywhere a truck can reach, including remote farm sites, fairgrounds and construction lots without utilities yet. Portable sink water tanks range from small 5 gallon units for a single-person job to larger tanks for stations serving a full crew or event line. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and a filled tank on a portable sink station meets that without waiting on a permanent line. For farm labor sites, OSHA 1928.110 sets a stricter bar: potable water, toilets and handwashing within a quarter mile walk, at one facility per 20 workers. That standard shows up often on jobs we serve out near Cheney, 17.4 miles southwest of Spokane, and Four Lakes, 11.9 miles southwest, where crews are spread across open ground. Check our farm and agricultural restrooms page if that's your situation, or look at construction site services for a fuller sanitation package.
Delivery trucks need roughly 60 feet of straight clearance to place larger combined units, similar to what's needed for a roll-off, so let us know if your Spokane site is tight before we schedule a drop-off. If you're stacking services, our construction dumpster rental and temporary power pole pages cover what else typically shows up on a build site alongside a sink station.
How many portable sink stations do I need for a crew?
For a general jobsite, plan sink access wherever you've placed toilets, roughly matching your how many porta potties do I need count. OSHA 1926.51(c) sets toilet ratios by crew size; put a sink near each cluster rather than one station serving the whole site.
Is a heated portable sink available in Spokane?
Yes, some units include a small water heater, useful for winter jobs or hair washing. Ask when requesting a quote, since not every station in the fleet is heated. Check porta potty in winter for related cold-weather setup notes.
Can I rent just a portable sink without a toilet?
Yes. Standalone sink rentals work for food vendors, film sets and small crews that already have toilet access. Delivery still applies. Ask about combining with event restroom rental if your event grows.
How often is the water tank refilled or serviced?
That depends on usage and tank size; high-traffic events may need a mid-week refill. ANSI/PSAI Z4.3 sets a baseline weekly service interval for portable sanitation equipment generally, which we follow unless your event needs more frequent visits.
Do portable sinks work for camping trips?
Yes, a basic camping portable sink with a small hand-pump tank suits a weekend trip or a remote worksite. For longer stays, step up to a larger tank so you're not hauling water refills constantly. See camping porta potty for pairing options.
