What Is a Portable Sink Rental?
A portable sink station is a standalone unit with a fresh water tank, a basin, a foot pump or hand pump, and a wastewater holding tank underneath. No hose bib, no drain line, nothing to tie into. That is the whole point. You place it where people actually need it: next to a portable restroom rental, by a food booth, or outside a work trailer. Boulder Porta Pros stocks basic hand wash units and a few upgraded portable sink stations with hot water heaters built in, which matter more than people expect once fall temperatures drop. Under 29 CFR 1910.141(d)(2), washing facilities need soap and a way to dry hands, hand sanitizer does not count as a substitute, so every unit we deliver in Boulder comes stocked with both. If you are also renting toilets for the same job, pair this with a standard porta potty rental or check the full portable toilet rental lineup and save a trip.
Can You Wash Your Hair in a Portable Sink?
Yes, with the right unit. A camping portable sink or a basic hand wash station works fine for hands and dishes, but washing hair calls for more basin depth and a hose sprayer rather than a small pump spout. If you need a portable sink to wash hair for a film shoot, a fitness event, or post-race rinse-off near a marathon and race restrooms setup, ask about our deluxe units when you request a quote. A portable sink for hair washing works best with warm water, so a hot water portable sink station beats a cold-tank unit for that use every time. For a full rinse rather than a rinse-and-go, a shower trailer rental is the better fit, and for weddings or upscale events a luxury restroom trailer often already includes a sink built into the trailer itself.
How Big Are the Water Tanks?
Tank size depends on the unit, but most portable sink water tanks run in the same range as a standard portable restroom's holding tank, which is 60 to 70 gallons on our standard equipment. That is enough for a full day of moderate hand washing before a refill is needed. Higher-traffic events, like a festival restroom rental setup or a county fair restrooms booking, may need two stations or a mid-day top-off visit. We size the portable sink and water tank combination to headcount and hours, not guesswork. Construction crews in Boulder also lean on these for general site cleanup alongside a construction dumpster rental, since OSHA 1926.51(c) sets toilet ratios by crew size and a sink station nearby keeps hand washing compliant and convenient without a separate trip to a trailer.
Do You Need a Permit for a Portable Sink Station?
Placement in the public right of way in Boulder needs confirming with the city before delivery day, since a portable sink station on a sidewalk or street shoulder is treated differently than one placed on private property. We have not verified a specific local ordinance number for this, so check with the city's permitting office directly if your placement touches a public easement or street. For most residential driveways and private lots, no permit conversation is needed at all. If your event also needs barrier or crowd control, look at temporary fence rental or a crowd control barrier rental while you are sorting out placement questions, and see our porta potty placement guide for the same right-of-way logic applied to toilets.

Boulder crews building near Valmont, about 3.5 miles east, or Louisville, roughly 9.4 miles southeast, often bundle a sink station with a monthly porta potty rental for longer jobs. Lafayette sits about 10.1 miles east and Erie about 13.9 miles east, both within our standard delivery radius, and Broomfield is roughly 15.5 miles southeast if your project spans multiple sites.

How much does a portable sink rental cost in Boulder?
Sink stations are usually bundled with toilet or trailer rentals rather than priced alone, with delivery running $100 to $150 for a single day. Ask for a quote with your full equipment list and Boulder Porta Pros will price the sink station alongside it.
Does a portable sink need electricity?
No. Standard units run on hand or foot pumps and need no power hookup. Hot water models use a small internal heater powered by the unit's own battery or a low-draw connection, not a full circuit, so no electrician visit is required.
How often does the water tank need refilling?
Most portable sink water tanks last a full day of moderate use before needing a refill, similar to the 60 to 70 gallon cycle on our standard restroom units. High-traffic events may need a mid-day top-off, which we can schedule in advance.
Can I rent just a sink without a toilet?
Yes. Standalone sink stations are available for job sites, markets, and film shoots that only need hand washing. Many customers still pair one with a porta john rental for full coverage, but it is not required.
Is a portable sink required on a construction site?
OSHA 1926.51(c) sets toilet facility ratios by crew size, and a hand wash station nearby helps satisfy general sanitation expectations tied to those requirements. Check our OSHA portable toilet requirements page for the full ratio table before your next inspection.
