What Is a Portable Sink Station?
A portable sink station is a standalone basin unit built around its own portable sink water tanks. Fresh water sits in one tank, gray water drains into a second, and a foot pump or battery pump moves water to the faucet. No sewer line, no well, no problem. Waukesha Porta Pros pairs these with handwashing station rental packages for job sites, or as a standalone portable sink rental for events around Waukesha. Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand-drying device, since hand sanitizer alone does not satisfy that standard, and our units come stocked to meet it. Some renters ask about a portable sink for hair washing at outdoor weddings or film shoots, and the same basin design works fine for that, especially paired with a wedding restroom rental or a film set restroom rental. For crews doing paint or coating work, OSHA 1926.51(f)(1) requires washing facilities specifically because of the contaminant exposure, and a sink station covers that need directly.
Do Portable Sinks Have Hot Water?
Yes, hot water portable sink units are available and run off a small internal heater or a pre-heated tank, useful for washing hands in a Waukesha winter or for anyone who wants a portable sink to wash hair without cold shock. Standard cold-water units cost less and work fine for job sites. Heated units cost more but matter for camping porta potty setups, hunting camps, or any long event where guests expect more than a splash of cold water. If your event also needs full showers, look at a shower trailer rental instead, since sink stations handle hands and hair but not a full rinse. Waukesha Porta Pros delivers both types the same way we deliver our standard porta potty rental units, on a set schedule with tank refills included.
How Much Does a Portable Sink Rental Cost in Waukesha?
Pricing depends mostly on rental length and whether you need a heated unit. Below is what a comparable standard restroom unit costs across the same durations, since sink stations typically price close to standard units when rented together as a package.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $100 | $150 | $350 |
| Week | $130 | $200 | $500 |
| Month | $125 | $200 | $325 |
A delivery fee applies on top of the rental, and most delivery charges for a single site in Waukesha fall between $100 and $150 for a day rental. Renting a sink station alongside a porta john rental or deluxe flushable porta potty often saves a separate delivery trip.

Longer jobs benefit from monthly porta potty rental terms, and the same logic applies to sink stations rented for extended construction timelines.
Why Do Job Sites Need a Portable Sink?
Construction crews need handwashing access as part of general sanitation compliance. OSHA 1926.51(c) sets toilet facility ratios by crew size, from one toilet for 20 workers or fewer, up to one toilet and one urinal per 50 workers at 200 or more, and a sink station rounds out that setup with actual water access. OSHA 1926.51(a)(1) also requires an adequate supply of potable water at all places of employment, which a portable sink water tank satisfies directly on sites without hookups. Agricultural operations fall under a different rule: OSHA 1928.110 requires field sanitation with potable water, toilets, and handwashing within a quarter mile walk of hand-labor employees, one facility per 20 workers, which matters for farm and agricultural restrooms around Waukesha County. Waukesha Porta Pros services construction sites 8.2 miles from New Berlin and 9.4 miles from Brookfield on the same route, so multi-site jobs get one consistent service day. Pair a sink station with temporary fence rental or a light tower rental and the whole site perimeter is covered. For food service trailers, a grease trap pumping schedule matters too, since fats and grease get pumped once they reach 25 percent of the liquid depth in the interceptor.
How often does a portable sink get refilled and serviced?
Waukesha Porta Pros follows a schedule similar to the ANSI/PSAI Z4.3 baseline used across portable sanitation, generally one service visit per week for moderate use. High-traffic events or large crews need more frequent refills. We coordinate this with your septic pumping service or toilet servicing so trucks visit once, not twice.
Can I rent a portable sink for a single weekend event?
Yes, weekend sink rentals are common for weddings and festivals. A standard restroom unit weekend rate typically runs $125 to $400 in Waukesha, and sink stations rented as an add-on follow a similar range. Check event restroom rental or festival restroom rental for full package options.
Do I need a permit to place a portable sink on my property?
Placement in the public right of way needs confirming with the City of Waukesha before delivery. Private property setups generally do not need the same review. See porta potty permit requirements for a fuller breakdown, or ask us directly when booking.
What size water tank comes with a portable sink station?
Tank sizes vary by unit and use case, from small basin tanks up to full portable sink water tanks matching the 60 to 70 gallon holding tank capacity found on our standard porta potty rental units. Heavier-use events need larger tanks and more frequent refills.
Can a portable sink work for handwashing after using pesticides or paint?
Yes. OSHA 1926.51(f)(1) specifically requires washing facilities where workers apply paints, coatings, herbicides or insecticides, and a portable sink station with soap and towels satisfies that requirement directly on site.
