A porta potty holds waste and chemical deodorizer in a sealed tank below the seat, usually 60 to 70 gallons, with no water hookup needed. Dearborn Heights Porta Pros delivers, sets up, and services these units on a schedule, so the tank never gets close to full between visits.
A standard unit is a self-contained box, about 44 by 48 inches on the ground and 92 inches tall, sitting over its holding tank. No plumbing, no power. The blue liquid you see is deodorizer and a breakdown agent that keeps solids from building up between service stops. When a construction worker running to a porta potty on a busy site finds the door, that unit is one of several placed to match crew size, following OSHA 1926.51(c) ratios: one toilet for 20 workers or fewer, then one toilet and one urinal per 40 workers up to 200. We work out those counts up front, whether it is a small remodel crew or a full construction site services package. Placement matters too. Units need firm, level ground and clear truck access for our pump truck to service them on schedule, which is where a porta potty placement guide helps before delivery day. Most renters start with our standard porta potty rental line, then add units as headcount grows. If you are still working out numbers, how many porta potties do I need walks through it by worker count and event length.
A flushable, or deluxe, unit uses a small onboard freshwater tank and a foot pump or handle to rinse the bowl after each use, instead of relying only on the holding tank chemical. Waste still drops into the same style of sealed holding tank below, just with a rinse cycle added, which cuts odor noticeably compared to a standard unit over a full week of ANSI/PSAI Z4.3 service intervals. Our deluxe flushable porta potty units run this way and suit weddings, office sites, and longer-stay rentals where guests expect more than a standard unit offers. For crews or events needing ADA access alongside deluxe features, our ADA accessible porta potty units meet ADA Standards 404.2.3, a 32 inch clear door opening, and include the 60 inch turning circle required under ADA Standards 304.3.1. Where units cluster on one site, ADA Standards 213.2 requires at least 5 percent of the group, and never fewer than one, to be accessible. If you are pricing options, porta potty rental cost breaks down what pushes a quote toward deluxe versus standard.
A portable sink is a separate self-contained unit with its own fresh water tank, a foot pump or hand crank to move water to the tap, and a holding tank underneath to catch greywater, so it needs no plumbing hookup either. Under 29 CFR 1910.141(d)(2), washing facilities need soap and towels or a hand-drying device, and hand sanitizer alone does not satisfy that. We pair portable sink rental units with restroom rentals on food service sites, agricultural crews, and any job where painting, coatings, or pesticide work falls under OSHA 1926.51(f)(1), which specifically covers washing after paints, coatings, herbicides or insecticides. Farm operations in and around Dearborn Heights often pair units this way too, since hand-labor employees fall under OSHA 1928.110 field sanitation rules requiring a facility within a quarter mile walk. If sanitizer-only setups are what you are considering instead, our hand sanitizer station rental page explains where that is and is not enough.
Camping and remote-site units work the same way mechanically, sealed tank, chemical breakdown, no plumbing, but service intervals stretch out since sites are harder to reach and usage is lighter than a job site. We still plan around ANSI/PSAI Z4.3's baseline of weekly service for lighter-use groups, then adjust based on headcount and how long the group is staying. Camping and outdoor event renters in Dearborn Heights often start with a camping porta potty unit and skip the deluxe upgrade since power and water access are limited anyway. Longer stays, like a month-long crew stationed near Redford, 4.4 miles north, or a weekend event site near Garden City, 3.4 miles west, change which service plan makes sense. Weekly and monthly renters should check monthly porta potty rental pricing before committing, since a longer stay changes the math compared to a single day.
| unit | day | week | month |
|---|---|---|---|
| standard | $100 - $350 | $130 - $500 | $125 - $325 |
| ada | $200 - $400 | $240 - $400 | -- |
| deluxe | $85 - $1200 | $150 - $290 | -- |
Delivery runs $100 to $500 for a day rental and $120 to $420 for a month, separate from the unit itself. See porta potty rental per day for shorter jobs, or porta john rental if you are comparing unit types by name.
The blue liquid in the holding tank is a deodorizer and biocide blend that breaks down waste and controls odor between services. It is not the same as septic tank cleaning chemicals used in a home system. We handle chemical loading as part of every service visit, so renters never need to buy or add anything themselves.
ANSI/PSAI Z4.3 sets a baseline of one service visit per week for units used by up to 10 people over a 40 hour week. Heavier-use sites, like busy construction crews, often need two visits weekly. Check how often are porta potties cleaned for how we scale that by headcount.
No. Every unit works off its own sealed tank, with deluxe models adding a small onboard freshwater reservoir for rinsing. That is the whole appeal on remote sites. For sites also needing lighting, light tower rental and temporary power pole options run separately from restroom service.
A residential septic tank is a fixed underground system, typically pumped every 3 to 5 years depending on tank size and household size, while a porta potty is a portable, self-contained unit serviced weekly. If your home system needs attention, septic pumping service covers that separately from portable rentals.
It needs firm, level, stable ground, similar to the slip-resistant surface standard under ADA Standards 302.1, so our crew can set it without tipping risk and our service truck can reach it. Gravel, pavement, and packed dirt all work. Soft grass or a slope usually does not.
