What Is a Portable Sink Station?
A portable sink station is a self-contained basin with a fresh water tank, a wastewater tank underneath, and a foot pump or hand pump to move water through the faucet. No plumbing hookup, no generator required on most units. Ann Arbor Porta Pros sets these up next to standard porta potty rental units on construction sites, or as a standalone piece for events and farm crews who need a place to wash up between tasks. Some renters use them as a portable sink for hair washing at outdoor events, camps, or film shoots where a real shower trailer isn't practical. A shower trailer rental is the better call if you need full-body rinsing for a crew, but a sink station covers hands, faces and quick hair rinses fine. Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand-drying device, not just a water source, and hand sanitizer alone does not meet that standard. Ann Arbor Porta Pros stocks units with soap dispensers built in, so that requirement is covered without extra deliveries. Pair a sink station with a portable sink rental delivered alongside your temporary fence rental perimeter and you have a clean, contained work zone.
How Does a Portable Sink and Water Tank Work?
Fresh water sits in an upper or side tank, gravity-fed or pumped down to the faucet, and drains into a separate holding tank below the basin. Most stations hold enough water for several days of moderate hand-washing before a refill is needed, and Ann Arbor Porta Pros handles refills on the same schedule as septic pumping service stops if a site has both. Hot water portable sink units add a small heating element or insulated tank so hands don't go under cold water in November. That matters for a city where winter service already needs extra planning, and our porta potty in winter guide covers freeze protection for the whole rental lineup. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and a sink station with a sealed fresh tank satisfies that without running a hose from a spigot two blocks away. For construction crews, that same site likely needs a toilet count under OSHA 1926.51(c)(1): one facility for 20 workers or fewer, scaling up from there. Ann Arbor sites near downtown or the university corridor often run tight on space, so a compact sink station next to a porta john rental unit uses less footprint than a full trailer.
Can I Use a Portable Sink for Camping?
Yes, and it's one of the more common requests we get outside of job sites. A camping portable sink works the same way as a construction-site unit, just smaller and easier to move by hand. Renters near Scio, 6.6 miles west of Ann Arbor, and Pittsfield, 6.1 miles south, use these for weekend group camps and family reunions where a fixed bathhouse isn't available. If you're planning a bigger outdoor event, check our camping porta potty page or the broader event restroom rental options, since sink stations rent well alongside a standard porta potty rental or deluxe flushable porta potty for weddings and festivals. ADA Standards section 308.2.1 sets forward reach limits at 48 inches maximum and 15 inches minimum, and section 309.4 requires operable parts usable with one hand and no more than 5 pounds of force, both worth checking if your event needs an ADA accessible porta potty paired with an accessible sink. Farms running hand-labor crews should also look at farm and agricultural restrooms, since OSHA 1928.110 sets a separate standard for field sanitation.
What Does a Portable Sink Rental Cost?
Pricing for sink stations tracks close to standard portable toilet rentals since delivery, pickup and servicing follow the same routes. Ann Arbor Porta Pros quotes by the day, week or month, and delivery fees apply per trip regardless of unit type.
| duration | low | typical | high |
|---|---|---|---|
| day | 100 | 150 | 350 |
| week | 130 | 200 | 500 |
| month | 125 | 200 | 325 |
Delivery runs separately, from around 50 dollars on the low end for a weekly drop to several hundred for a same-day rush, and weekend rentals carry their own premium rate rather than a discount off the weekly price. For a full construction package with restrooms, sinks and a dumpster, see construction site services or check roll-off dumpster rental if debris removal is part of the job. Multi-unit orders across a bigger site sometimes bundle better through portable restroom rental than as one-off add-ons, so ask when you call. Renters comparing options across nearby towns can check porta potty rental in Ypsilanti, MI, 6.4 miles east, for regional pricing context.
Do I need a hot water unit or is cold water enough?
Cold water covers most hand-washing needs and costs less to service. Hot water portable sink units make sense for food service, medical settings, or cold-weather job sites where crews need it for comfort as much as compliance. Ask about heated units when you book if your Ann Arbor site runs through winter months.
How often does the water tank need refilling?
It depends on crew size and use, but most stations run several days between refills under normal hand-washing traffic. High-use events or larger crews may need daily service. Ann Arbor Porta Pros can schedule refills on the same route as toilet servicing to avoid extra delivery fees.
Can a portable sink replace a shower trailer for hair washing?
For a quick rinse, yes. For full showers, no. A sink station handles a portable sink for hair washing at a campsite or event fine, but crews needing full showers should look at a shower trailer rental instead.
Do portable sink stations need a permit in Ann Arbor?
Placement in the public right of way needs confirming with the city before delivery. For most private job sites and backyards no permit applies, but check our porta potty permit requirements page and confirm with the City of Ann Arbor if you're placing near a street or sidewalk.
What comes standard on a rented sink station?
Units include a fresh water tank, wastewater tank, faucet, and a soap dispenser to meet 29 CFR 1910.141(d)(2) requirements for washing facilities. Towels or a hand-drying device should be added if the dispenser doesn't include one. Ask Ann Arbor Porta Pros about add-ons when requesting a quote.
