Frequently asked questions
How many portable toilets do I need?
OSHA 1926.51(c)(1) sets the baseline: one toilet facility for 20 workers or fewer on a construction site, then one toilet seat and one urinal per 40 workers up to 20 employees, and one toilet seat and one urinal per 50 workers at 200 or more. The math changes fast once a crew grows, so a 100-person job needs way more than a 20-person job. An event in Champaign with 500 guests runs by different rules than a construction site. Duration matters too. A six-hour festival needs fewer units than a three-day event at the same headcount. We size your job by crew count, site layout, shift length and work type. Contact us with your numbers and we'll recommend the right fleet. See our guide on how many porta potties you actually need for the full breakdown.
What's the real cost of renting?
Porta potty rental cost runs by duration. A standard unit rented per day sits in the $100-$350 band depending on the market and what you add. Weekly rental is cheaper per day than daily, that's $130-$500 per week. Monthly porta potty rental costs $125-$325 per month. A deluxe flushable unit with running water and a flushing mechanism runs $85-$1,200 per day, or $150-$290 weekly. An ADA accessible unit that meets ADA Standards section 213.2 (at least 5 percent of clustered units must be accessible) costs $200-$400 daily and $120-$240 weekly. Delivery starts around $50-$500 depending on how far we travel from our Champaign base. Every quote accounts for your specific dates and site address.
What about septic pumping and grease traps?
A residential septic tank is typically pumped every 3 to 5 years, driven by tank size and household size. If you notice slow drains, backing up, or wet spots in the yard, that's a sign the tank needs pumping sooner. Septic tank pumping cost in Champaign runs $150-$300 for a service call. A grease interceptor is pumped when fats, oils, grease and solids reach 25 percent of the liquid depth, restaurants and food prep sites need this more often than residential kitchens. We handle grease trap pumping and septic tank cleaning on the same schedule as porta potty service. See how often to pump a septic tank for the detailed timeline.
Can I rent a restroom trailer instead?
Yes. A restroom trailer is a self-contained unit with flushing toilets, sinks, soap and hand-drying devices that meet 29 CFR 1910.141(d)(2), which requires soap and towels or a hand dryer in any washing facility. Trailers sit on your site for weeks or months and handle high-volume events better than standard units. We stock 2-stall, 4-stall and 8-stall models. Daily rental runs $175-$2,500 depending on stall count and amenities. Restroom trailer rental cost jumps sharply for events and premium units, but spreads lower across longer monthly rentals. A standard unit is about 44 by 48 inches on the ground and stands about 92 inches tall; trailers are far larger and require about 60 feet of straight clearance behind the truck for delivery.
