What is a portable sink station?
A portable sink station is a self-contained unit: a fresh water tank feeds a faucet, waste drains into a separate holding tank underneath, and a foot pump or battery pump moves the water. No hookup needed. Lee's Summit Porta Pros sets these up at construction sites, food booths, and backyard events across the city. Some units run hot water off a small heater, which matters if crews are washing up after handling anything greasy or working through a cold Lee's Summit winter, a season worth planning for ahead of time on our porta potty in winter page.
Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand-drying device on site. Ours come stocked. If your crew is applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities specifically for that contaminant exposure, and a portable sink satisfies it without trenching a water line. For general jobsite sanitation counts, see our breakdown of OSHA portable toilet requirements, since sinks and toilets often get budgeted together.
Pair a sink with a portable restroom rental or a full restroom trailer rental, and you cover both the OSHA 1926.51(c) toilet ratio and the handwashing requirement in one delivery. Our handwashing requirements page walks through which setup fits which job type.
Can a portable sink be used for washing hair?
Yes. A portable sink to wash hair works fine for campers, film crews, or event vendors who need more than a splash of water. Choose a model with a wider basin and a hot water option if you want it comfortable rather than just functional. We rent portable sink hair washing setups for camping porta potty packages, film set restroom rental jobs, and long-weekend events where showers aren't in the budget but hair washing still is.
If a full rinse-off is what you actually need, a shower trailer rental is the better fit. But for quick hair washing between takes or after a muddy hike near a Lee's Summit trailhead, a portable sink with a deep basin and a hand sprayer handles it. Water tank size drives how many washes you get before a refill; ask us about tank capacity when you book so it matches your headcount, not just your event length.
How does a portable sink water tank get refilled?
Our crew handles refills on a set schedule, matching the ANSI/PSAI Z4.3 baseline of one service visit per week for up to 10 users over a 40 hour week, though heavier-use events need more frequent stops. We track both tanks: the fresh water side and the waste holding tank underneath. When either runs low or full, we're back out. Lee's Summit sites within a normal service loop get priority scheduling, and jobs further out, like a delivery near Raymore 13.5 miles southwest or Blue Springs 11.2 miles northeast, get folded into the same route.
For construction sites already renting a roll-off dumpster rental or a temporary fence rental, we can service the sink on the same stop as the dumpster pull or fence check, which keeps delivery fees down. If you are not sure how many units your headcount needs, our how many porta potties do I need guide has the math, and it applies to sink stations too: more hands on site means faster tank turnover.
What does a portable sink rental cost in Lee's Summit?
Pricing depends on tank size, hot water, and rental length. Below are typical ranges pulled from comparable unit categories; ask for a sink-specific quote since stations vary by model.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $100 | $150 | $350 |
| Week | $130 | $200 | $500 |
| Month | $125 | $200 | $325 |
These bands mirror our standard unit pricing since sink stations are quoted similarly by rental length. Delivery runs separately, generally $100 to $150 for a single day drop-off. Full cost breakdowns, including what affects the final number, live on our porta potty rental cost and monthly porta potty rental pages. If you are comparing a short weekend event against a month-long job site, our porta potty rental per day page has that comparison laid out. For ADA-compliant placement near your sink station, ADA Standards section 304.3.1 requires a 60 inch turning circle, which we account for when we plan layout; more detail is on our ADA accessible porta potty page.
FAQ
Does a portable sink need to be near a porta potty?
Not strictly, but it's the practical setup. Most Lee's Summit job sites put the sink within a few feet of the porta john rental unit so workers wash up right after using it. OSHA 1926.51(c) governs toilet ratios separately from handwashing, but pairing them keeps compliance simple and keeps foot traffic in one spot.
Can I rent a portable sink for a single weekend event?
Yes. Weekend rentals run in the same range as our standard unit weekend pricing, generally $125 to $400. It works well for a wedding, a block party, or a wedding restroom rental package where guests need handwashing near the food or bar area without full plumbing.
Do portable sinks come with hot water?
Some do. Ask for the hot water portable sink option if your crew handles food, needs it for hair washing, or you're operating in cold months. Heated units run a small internal tank warmer and cost more than the standard cold-water version, so mention it when requesting a quote.
How many people can one portable sink water tank support?
It depends on tank size and how often we refill it. A 5 to 10 gallon tank handles light use for a small crew between service visits, while events need larger tanks or more frequent top-offs. Tell us your headcount and we'll size it, similar to how we size units using our how many porta potties do I need guide.
Is a portable sink enough for OSHA compliance on a job site?
It covers the handwashing piece, especially under OSHA 1926.51(f)(1) if your crew handles paints, coatings, herbicides or insecticides. You'll still need toilets sized to OSHA 1926.51(c) ratios. Most Lee's Summit contractors rent both together; see construction site services for the full jobsite setup.
