A portable sink rental gives crews and event guests real running water for washing hands or hair without hooking into a building. Southfield Porta Pros builds each station on a self-contained water tank, and standard units run in the same price band as our standard porta potty rental, from $100 to $350 a day depending on setup.
A portable sink station is a self-contained unit with its own fresh water tank, a pump, a basin and a wastewater tank underneath to catch the runoff. Nothing connects to city water or a sewer line. You fill the fresh tank, and the unit holds it until it needs a refill or a pump-out, similar to how a standard unit holds 60 to 70 gallons in its own tank. Some stations add a small water heater so crews get warm water instead of cold straight from the tank. Southfield job sites near Providence Hospital or along Northwestern Highway use these as a standalone handwash point, or paired with a porta john rental so workers have both fixtures in one spot. For events, we often set them next to a restroom trailer rental so guests are not queuing at a single sink. Soap and a towel or hand-drying device have to be there too, per 29 CFR 1910.141(d)(2), which is written for general industry sanitation but is a standard we build into every unit regardless of site type.
Yes. A portable sink for hair washing works the same way as any camping portable sink, just with a basin shaped for tipping your head back instead of scrubbing hands. We rent these for film sets, disaster relief camps and long-term construction crews who need more than a hand rinse. A hot water portable sink makes a real difference here, since washing hair in cold tank water is miserable in a Michigan fall. These units pair well with a shower trailer rental on multi-week jobs, or stand alone at a camping porta potty setup where guests want to rinse off after a hike near Bloomfield, 8.9 miles north of Southfield. Tank size matters for hair washing more than for a quick handwash, since rinsing shampoo runs through more gallons per person than a 10 second hand rinse does.
OSHA 1926.51(a)(1) requires an adequate supply of potable water at every place of employment, and a portable sink and water tank is how most Southfield job sites meet that away from a building hookup. If your crew works with paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) goes further and requires washing facilities specifically for that contaminant exposure, not just a general handwash setup. That is a different bar than the toilet count rule in OSHA 1926.51(c), which sets ratios like one toilet for 20 workers or fewer. A lot of contractors bundle a sink rental with a construction site services package that also covers a temporary fence rental and a roll-off dumpster rental, since all three tend to get ordered for the same permit. If you are not sure how many hand stations your crew needs, our how many porta potties do i need guide walks through the OSHA math, and the same headcount logic applies to sinks.
Pricing tracks close to our standard toilet units since delivery, service and tank size drive cost more than the fixture itself. A weekend rental costs more per day than a week-long rental, so short events pay a premium.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $100 | $150 | $350 |
| Week | $130 | $200 | $500 |
| Month | $125 | $200 | $325 |
Delivery adds a separate charge, typically $100 to $150 for a single day trip and $50 to $150 for a week-long placement, based on distance from our Southfield yard. A job near Oak Park, 4.9 miles east, costs less to service than one out toward West Bloomfield, 11.7 miles northwest. If you are comparing options across unit types, our portable sink rental pricing lines up closely with the numbers on our porta potty rental cost page, and monthly renters should check monthly porta potty rental for how multi-week jobs get discounted.

It depends entirely on crew size and how the sink gets used. A crew of 10 doing quick handwashes might stretch a tank across a full week, matching the ANSI/PSAI Z4.3 baseline of one service visit per week for up to 10 users over a 40 hour week. Hair washing or heavy kitchen-style use drains a tank faster, sometimes needing a refill every two or three days.
Yes. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at any washing facility, and hand sanitizer alone does not satisfy that standard. Every sink station from Southfield Porta Pros ships with a soap dispenser and paper towel holder stocked at delivery, and our service visits restock both along with the tank refill.
Some units include a small heater that warms the tank water, which matters most for hair washing or winter jobs. Cold-only units work fine for quick handwashing. Tell us at booking if hot water matters for your job, since not every unit in our fleet carries a heater and we need to match the right one to your site.
Placement in the public right of way needs confirming with the City of Southfield before delivery. For jobs entirely on private property, this usually is not an issue, but our porta potty permit requirements page covers the general questions to ask before you commit to a spot.
Yes, and most of our Southfield customers order them together. A sink station next to a portable restroom rental or a deluxe flushable porta potty covers both fixtures without running any plumbing, and it is the same logic behind our event restroom rental packages.
Yes. Southfield Porta Pros delivers portable sink rental across Southfield and the surrounding metro, with same-day and next-day drop-off available on most orders.
