Standard porta potty
$125 to $250 a weekend
Milwaukee, WI
A portable handwashing station is a freestanding sink with its own fresh water supply, a waste catch tank, soap and towels, and no plumbing connection at all. Milwaukee Porta Pros delivers them to construction sites, food events, farms and festivals across Milwaukee County. On most jobs it is not a nice extra, it is what keeps the site compliant.
OSHA 1926.51(f)(1) requires washing facilities on construction sites, and that requirement stands on its own regardless of how many toilets you have. A crew handling paints, coatings, solvents, herbicides or insecticides needs somewhere to wash before eating and at the end of the shift. Hand sanitizer alone does not replace soap and running water, which is the mistake we correct most often when a site calls in a hurry. If sanitizer is what you actually want as a supplement, that is a separate product on our hand sanitizer station rental page. The full regulation is unpacked in our handwashing requirements guide.
A standard portable station gives you a foot pump or push tap, a fresh water reservoir, a greywater catch tank underneath, a soap dispenser and paper towels. Nothing needs a hose bib or a drain, so the station can sit in the middle of a field, in a parking lot or on a slab with no utilities in sight. If you want a sink with a more finished look, see portable sink rental, and for events needing indoor-style restrooms with built-in sinks, the luxury restroom trailer covers both jobs in one unit.

Start from the toilet count and work outward. OSHA 1926.51(c)(1) sets one toilet for 20 or fewer workers, then one toilet seat and one urinal per 40 workers above 20, so a crew of 30 already needs more than a single fixture group. The ANSI/PSAI Z4.3 baseline of one unit per ten workers over a 40 hour week with one service visit is a useful cross check when the schedule is long. Practically, we place stations next to the restroom bank rather than off in a corner, because a sink nobody walks past is a sink nobody uses. Our how many porta potties do I need page runs the same math for the restroom side, and OSHA portable toilet requirements covers the citations in full.

Put it on firm, level ground within sight of the restrooms and along the path crews already walk. Keep it clear of trench edges, swing radii and vehicle routes. The same siting logic that applies to toilets applies here, and the porta potty placement guide covers ground conditions, access and wind exposure in more detail. On private property no permit is needed. If the station has to sit in the public right of way in Milwaukee, that placement may require a permit from the City of Milwaukee, which is covered on porta potty permit requirements.

Yes, more than it affects a toilet. A station carries standing fresh water, and Milwaukee winters on Lake Michigan are cold enough that an unprotected supply line or reservoir can freeze and split. From roughly November through March we plan for that: winter tank treatment on the restroom side, and a placement and service plan that keeps the sink usable rather than decorative. If a freeze is forecast and the site is going quiet for a stretch, tell us and we will schedule around it. Our porta potty in winter guide covers cold weather sanitation generally.
Handwashing stations are usually quoted as an add-on to a restroom order rather than on their own, because that is how sites actually use them. Delivery typically runs $50 to $150 depending on distance and access, and routine weekly service runs $30 to $60 per unit. The restroom side of the same order follows published bands: a standard porta potty rental runs $125 to $250 for a weekend and $125 to $325 for a month, a deluxe flushing unit runs $200 to $350 for a weekend, and an ADA accessible porta potty runs $199 to $300 for a weekend.
Yes. Under OSHA 1926.51(f)(1) the washing requirement applies regardless of how few toilets you have.
On the same visit as your restrooms in most cases. Fresh water gets refilled, greywater gets pumped, and soap and towels get restocked.
Yes, and food vendors often need one within reach of their booth. Pair it with an event restroom rental or festival restroom rental order so everything drops on the same run.
