What Is a Portable Sink Rental?
A portable sink station is a self-contained unit with a fresh water tank, a gray water holding tank underneath, and a pump, either foot-operated or hot water powered. Nothing plugs into your building's plumbing. You fill the fresh tank, and the sink drains into its own holding tank until it gets pumped out. Most units run soap and towel dispensers built into the frame, which matters because 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at washing facilities, not just sanitizer. That rule is why a lot of Waterbury contractors pair a sink station with their portable restroom rental instead of relying on gel dispensers alone. If your crew works with paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities for that specific exposure, and a portable sink station satisfies it on a site that has no running water. For general jobsite sanitation counts, see our OSHA portable toilet requirements page.
Can a Portable Sink Be Used to Wash Hair?
Yes. A portable sink for hair washing works the same way a standard unit does, just with more clearance around the basin and, ideally, a hot water tank rather than cold-only. Camping portable sink setups get used this way at festivals and long-term work camps around Waterbury, where a shower isn't practical but hair washing still needs to happen. If your event needs a full rinse-off option rather than sink-only, look at our shower trailer rental or a combination unit through restroom trailer rental. For weddings and receptions where guests expect a nicer handwashing setup near the restrooms, we typically recommend pairing sink stations with a luxury restroom trailer rather than running sinks alone.
Portable Sink Water Tank Sizes and Pricing
Portable sink and water tank setups vary by how many people are using them and how often the tanks need refilling or pumping. A single hot water portable sink station suits a small crew or a market booth; larger events need multiple stations spaced around the site, similar to how we plan spacing for a portable toilet rental layout. Pricing below reflects our measured rental bands for comparable standard equipment.
| duration | typical range |
|---|---|
| day | $100 - $350 |
| week | $130 - $500 |
| month | $125 - $325 |
A delivery fee applies separately and typically runs $50 to $150 for a weekly rental, based on drive distance from our yard. If you're budgeting a whole job, our porta potty rental cost and porta potty rental per day pages break down how delivery and duration stack for combined orders. For jobs running a full season, monthly porta potty rental pricing follows a similar curve.
Why Do Job Sites Need Portable Sink Stations?
Construction crews without a water hookup still fall under OSHA 1926.51(a)(1), which requires an adequate supply of potable water at all places of employment, and general sanitation facility counts fall under OSHA 1926.51(c). A sink station is the simplest way to check that box on a site that's still waiting on utilities. Farms have their own version of this rule: OSHA 1928.110 requires potable water, toilets and handwashing for hand-labor employees, with a facility within a quarter mile walk, which is why our farm and agricultural restrooms packages usually include a sink unit. Food trucks and vendors at fairs need handwashing separate from customer-facing counters, something we set up alongside county fair restrooms and festival restroom rental orders. For sites already renting a temporary power pole or a light tower rental, adding a sink station to the same delivery keeps everything on one invoice. Waterbury sites within about 12 miles of Bristol or Southington get the same delivery windows we quote in town, since both towns sit inside our regular route.
If your project already needs a dumpster on site, check roll-off dumpster rental or the sizing breakdown at dumpster sizes and dimensions, since sink stations often go out on the same truck as a 10 yard dumpster rental for renovation work. Homeowners doing a gut renovation without indoor plumbing access sometimes rent a sink alongside a home renovation porta potty setup rather than run water from inside the house.
Do portable sinks come with hot water?
Some do. Hot water portable sink units heat water on demand or hold a heated reserve, which matters for hair washing, food service handwashing, or winter jobs. Cold-only foot pump units cost less and work fine for basic OSHA compliance. Ask which type you need when you request a quote.
How often does the tank need refilling or pumping?
It depends on crew size and use, similar to how a grease interceptor gets pumped once fats, oils, grease and solids reach 25 percent of the liquid depth. For steady daily use, we typically service sink stations on the same visit as nearby restrooms, following the same weekly baseline used for standard units under ANSI/PSAI Z4.3.
Can I rent just a sink station without a portable toilet?
Yes, sink stations rent on their own. Many food vendors and small crews only need handwashing, not a full restroom. Delivery and pricing work the same way as a standalone unit, and you can combine it later if the job scope grows.
Is a portable sink ADA accessible?
Not automatically. Standard sink stations sit at a fixed height. If you need accessible reach ranges, ask about ADA-compliant configurations, and check our ADA accessible porta potty page for related accessibility specs used across our rental line.
What is the delivery area for portable sink rentals?
We deliver throughout Waterbury and into nearby towns, including Bristol at roughly 11.9 miles and Southington at roughly 12.4 miles. See service areas for the full list, or request a quote with your address for exact delivery timing.
