What is a portable sink rental and how does it work?
A portable sink station is a self-contained unit built around a fresh water tank, a pump, and a wastewater tank underneath to catch the runoff. No plumbing hookup needed. Most models use a foot pump or a hand pump to push water through the tap, and some come with an on-demand heater for warm water in cold months. That matters here, since porta potty in winter planning usually means asking about heated options too. Under 29 CFR 1910.141(d)(2), handwashing facilities need soap and towels or a hand-drying device, not just a tap, and hand sanitizer alone does not satisfy that. We stock units with soap dispensers and paper towel holders built in, which covers that requirement on a job site or at a food booth. For events pairing sinks with restrooms, check the event restroom rental page or the wedding restroom rental guide for combo pricing. Delivery across Gresham typically runs same day if you call ahead, and setup takes about fifteen minutes once the unit is off the truck.
Can I use a portable sink for hair washing or camping?
Yes. A portable sink for hair washing works well when it has a deeper basin and a flexible hose spout, and several of our hot water portable sink models are built exactly for that. Campers use the smaller camping portable sink units for dishes and quick rinses, and food vendors use the larger stations for constant handwashing between orders. If you are running a booth at something like a festival, look at the festival restroom rental or concert restroom rental pages, since those events usually need multiple wash stations spaced along the food row. A portable sink and water tank setup with a 20 gallon fresh tank will handle a moderate-traffic booth for most of a day before a refill, though high-volume hand washing burns through that faster. We also rent these for film set restroom rental jobs where crew need a wash station near catering but off the main set. Farm labor crews fall under a different standard: OSHA 1928.110 requires field sanitation with potable water, toilets and handwashing within a quarter mile walk for hand-labor employees, which our farm and agricultural restrooms packages are built around.
How much does a portable sink station cost in Gresham?
Pricing depends on tank size, whether you need hot water, and how long you need it. A basic cold water sink station runs less than a heated model with a larger tank, and monthly rentals bring the daily rate down noticeably for job sites that need one parked for weeks. Delivery is a separate line item, and it scales with distance and how many units go out on the same run.
| item | duration | typical price |
|---|---|---|
| delivery fee | day | $150 |
| delivery fee | week | $100 |
| delivery fee | month | $172 |
| service fee | week | $60 |
| service fee | month | $150 |
These numbers reflect delivery and service fees measured across the region, not the sink unit rental itself, since sink station rates vary more by model than our other equipment. For an exact quote, tell us the job length and whether you want hot water, and we will match it to what is running that week. If you are also renting a roll-off dumpster rental or temporary fence rental for the same site, bundling delivery often saves a trip charge.
Do I need a handwashing station on my job site?
If workers are applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities for that specific exposure, separate from general sanitation. General toilet and sanitation counts on a construction site fall under OSHA 1926.51(c), which sets ratios based on crew size, and a water supply requirement under OSHA 1926.51(a)(1) covering potable water at the site. Neither rule mandates a sink station by name, but many supervisors add one anyway because it keeps a crew from tracking chemical residue into a portable toilet or break area. For a full breakdown of what OSHA expects on a construction job, see OSHA portable toilet requirements and handwashing requirements. Confirming placement in the public right of way, if that applies to your Gresham site, still needs a check with the city since that rule was not verified for this page. Renovation crews doing paint or coating work inside a home should look at home renovation porta potty for a combo package that adds a wash station without a second delivery fee. Construction managers building out a full site package can start from construction site services and add sinks, fencing and a dumpster in one order.
Frequently asked questions
How many portable sinks do I need for my crew?
For most crews, one sink station per 10 to 15 workers keeps lines short during breaks and lunch. Larger sites often add a second station near a paint or coating area to meet OSHA 1926.51(f)(1) requirements. See how many porta potties do I need for a matching toilet count.
Does a portable sink need a water hookup?
No. Every unit runs off its own onboard tank, filled before delivery, so it works anywhere in Gresham or out toward Troutdale, 4.7 miles northeast, without a hose bib nearby. You just need level ground for setup.
Can I get hot water in a portable sink rental?
Yes, several models include an on-demand heater. These cost more than a cold water unit but are worth it for hair washing, food service, or winter jobs. Ask when you book so we bring the right tank size.
How often does the water tank need refilling?
It depends on traffic. A 20 gallon tank on a moderate-use station usually lasts most of a workday. High-volume food booths or hair washing stations may need a midday refill, which we can schedule as part of service.
Can I rent a portable sink with a porta potty together?
Yes, this is the most common combo we deliver. Pairing a sink station with a portable restroom rental or porta john rental on one delivery run usually costs less than booking them separately through two calls.
