What Is a Standard Porta Potty?
This is the unit everyone pictures: a single-stall booth about 44 by 48 inches on the ground and roughly 92 inches tall, sitting on a 60 to 70 gallon holding tank. No sink, no flush handle, no lights. Just a seat, a door, and enough tank capacity to get a crew through a week without a mid-project pump-out. Chattanooga Porta Pros stocks these for construction site services, backyard renovations, and one-day events alike. If you want something nicer, the deluxe flushable porta potty adds a flush mechanism and a sink, and the ADA accessible porta potty meets a wider footprint requirement. But for most jobs, standard is the right call and the cheaper one. Compare it against the portable toilet rental lineup or the porta john rental page if you're not sure which category fits. For a construction crew in Chattanooga running five or ten workers, one standard unit usually covers the OSHA ratio without upgrading to anything larger.
How Much Does a Standard Porta Potty Rental Cost in Chattanooga?
Price depends on how long you need it and how many units you're ordering. Here's the range we see across the Chattanooga market:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $100 | $150 | $350 |
| Week | $130 | $200 | $500 |
| Month | $125 | $200 | $325 |
| Weekend | $125 | $250 | $400 |
| Event | $200 | $400 | $800 |
A delivery fee usually applies on top of the rental, and that runs separately depending on distance and how fast you need it. Multi-day construction rentals almost always beat the per-day rate of a one-off weekend booking. If you're budgeting a longer project, the monthly porta potty rental page breaks down what changes at 30-plus days, and the porta potty rental per day page is worth a look if you only need one delivery.

How Many Standard Units Do I Need?
For construction crews, OSHA 1926.51(c)(1) sets the baseline: one toilet facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you cross 20, dropping to one per 50 workers at 200 or more. A five-person framing crew in East Ridge, 6.6 miles south of Chattanooga, needs exactly one unit. A 45-person crew building out a site in Collegedale, 13.6 miles east, needs two. For events, the math is different and driven by headcount and hours, not labor law. Our how many porta potties do I need guide walks through both scenarios in more detail, and OSHA portable toilet requirements covers the full ratio table if your crew size sits near a breakpoint. Don't forget water: OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, separate from the toilet count itself. If your crew works with paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) also requires washing facilities on top of the standard toilet count.
Where Can I Place a Standard Porta Potty on My Property?
Placement in Chattanooga needs a stable, level surface within reach of a service truck; our drivers need clear approach for pump-outs on the schedule you choose. If you're near a public street or sidewalk, placement in the right of way needs confirming with the city before delivery, since we can't cite a specific local ordinance here without checking it against current code. For residential jobs in Red Bank, 9.3 miles northwest, or Signal Mountain, 14.1 miles northwest, most units end up in a driveway or side yard, no permit conversation needed. If you're clustering multiple standard units for a larger event, ADA Standards section 213.2 requires at least 5 percent of clustered units to be accessible, never fewer than one. Our porta potty placement guide covers ground surface, clearance, and slope in more depth, and porta potty permit requirements is the place to check before you commit to a spot near a curb or shared property line.
How often is a standard porta potty serviced?
ANSI/PSAI Z4.3 sets the baseline at one service visit per week for up to 10 users over a 40 hour week. Busy events or larger crews need more frequent pump-outs. We schedule around your actual usage, not a fixed calendar, and adjust mid-rental if your headcount changes. See how often are porta potties cleaned for the full breakdown.
Do standard porta potties smell?
Not if they're serviced on schedule. Odor comes from a tank nearing capacity or a missed service date, not the unit itself. Ventilation and chemical treatment in the tank handle most of it between visits. Our do porta potties smell page covers what actually causes odor and how to prevent it.
What size is a standard porta potty?
About 44 by 48 inches on the ground and roughly 92 inches tall. That's small enough to fit a driveway corner or a tight jobsite footprint without blocking equipment access or truck paths.
Can I rent a standard porta potty for just one day?
Yes. Day rentals run $100 to $350 depending on delivery distance and timing. Weekend and week-long rentals cost more in total but less per day, so check the porta potty rental per day page if your event is short.
Is a standard unit enough for a construction crew?
For most crews under 20 workers, yes, per OSHA 1926.51(c)(1). Larger crews need additional units scaled to headcount. Our construction site services page covers bundling toilets with dumpsters and fencing for bigger jobs.
