What Is a Portable Sink Station?
A portable sink station is a self-contained unit with a fresh water tank feeding the faucet, a grey water tank catching the runoff, and a basin sized for real handwashing or hair washing. It needs no plumbing hookup. Modesto Porta Pros builds these around the same water tank principle used in our handwashing station rentals, just scaled up for washing more than hands. Some crews pair a portable sink with a portable restroom rental so workers have both facilities in one spot. Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand-drying device on site, not sanitizer alone. That rule was written for general industry handwashing, but it's the standard we build every portable sink around, whether it's headed to a construction lot or a backyard wedding needing event restroom rental support.
Can a Portable Sink Wash Hair?
Yes. A portable sink with a hot water option is what most people mean by "portable sink for hair" or "portable sink to wash hair," and it works fine for film sets, salons doing outdoor days, or disaster recovery volunteers who need to rinse out debris. Hot water portable sink units cost more than a cold-water basin, so tell us the use case when you call. We've set these up for film set restroom rental jobs around Modesto where a stylist needed running water between takes. For events with heavier traffic, some clients upgrade to a deluxe flushable porta potty instead, since it includes its own sink. Camping portable sink setups follow the same logic on a smaller footprint, good for a family camp weekend near Riverbank, 8.8 miles northeast of Modesto.
How Much Does a Portable Sink Rental Cost?
Pricing depends on tank size, hot water, and how long you need it. Here's what fits inside our measured range for add-on sink units and their delivery:
| Item | Day | Week | Month |
|---|---|---|---|
| Sink station add-on | - | $30 - $60 | - |
| Delivery fee | $100 - $150 | $100 - $150 | $120 - $172 |
A week-long rental is the common term for construction crews and events. Monthly delivery runs higher than a one-time weekend drop because we're scheduling return service, not just a single trip. For a bigger picture on what porta potties cost alongside a sink add-on, check our porta potty rental cost breakdown or the monthly porta potty rental page if you're renting for a longer stretch. Job sites already tracking toilet costs by the day can compare against our porta potty rental per day numbers too.
Why Do Job Sites Need a Portable Sink and Water Tank?
Construction crews handling paints, coatings, herbicides or insecticides fall under OSHA 1926.51(f)(1), which requires washing facilities for that kind of contaminant exposure specifically, not general dirt. A portable sink and water tank combo satisfies that need without running a hose from a break trailer. General toilet facility counts on construction sites still follow OSHA 1926.51(c)(1): one toilet for 20 workers or fewer, then one toilet and one urinal per 40 workers as the crew grows past that. Farms doing hand labor fall under a different rule, OSHA 1928.110, which calls for one facility per 20 workers within a quarter mile walk, and a sink station often gets paired with that setup on operations we've served near Ceres, 4.1 miles southeast of Modesto. If you're not sure how many units your crew needs, our how many porta potties do I need guide walks through the math, and the OSHA portable toilet requirements page covers the citations in full. Water tank sizing on our sink units mirrors the fresh water supply logic behind ADA Standards 308.2.1, which sets reach ranges so a wheelchair user can operate the faucet without stretching past 48 inches high or under 15 inches low.
Site services beyond sinks are common add-ons too. Crews renting a temporary fence rental or a light tower rental for a Modesto job often bundle sink stations into the same delivery run to save on the fee. Storage needs get covered separately through our storage container rental options, and dumpster questions belong on our roll-off dumpster rental page. For the full lineup of what we haul to a single Modesto address, see construction site services.
How long can I rent a portable sink station?
Day, week or month, whatever the job needs. Most construction crews rent by the week to match their toilet rental term, while events usually book a single day or weekend. Longer terms lower the daily cost, same as our toilet rentals.
Does a portable sink need a water hookup?
No. It runs off its own fresh water tank and drains into a grey water tank, so it works anywhere a truck can deliver it, including remote lots near Bret Harte or Rouse.
Can I rent a hot water portable sink for hair washing?
Yes. Hot water units cost more than cold-water basins and are common for film sets, salons, and event styling stations. Tell us the intended use when booking so we bring the right model.
Do portable sinks meet OSHA handwashing rules?
They can. Under 29 CFR 1910.141(d)(2), a washing facility needs soap and towels or a hand-drying device, and our sink stations are stocked to meet that standard. For paint, coating, herbicide or insecticide work, OSHA 1926.51(f)(1) applies specifically.
