How Many Porta Potties Do I Need for an Event?
Anyone planning portable toilet rental for events asks this first.
A rough guide: 1 unit per 50 guests for a few hours, more if you are serving alcohol or running past four hours. This is not an OSHA workplace, but the same logic behind OSHA 1926.51(c) toilet ratios for job sites, roughly 1 seat per 20 workers, tells you why headcount drives unit count. For a wedding of 100 in Casper, plan on at least 2 standard units plus 1 ADA accessible unit, since ADA Standards section 213.2 requires at least one accessible unit in any cluster, even a small one. Festivals and fairs need more, spread across the grounds so lines never form in one spot, and a porta potty event party with drinking guests should size up from the baseline. Our placement guide walks through where units go relative to food tents, parking and power. If your event runs multiple days, a porta potty rental checklist helps you plan delivery timing so units are ready before guests arrive, not during setup. Not sure where to start? Our how many porta potties do I need page has a fuller breakdown by event type. For weddings specifically, see our dedicated wedding restroom rental guide.
What Kind of Restroom Fits a Casper Event?
Good event restroom trailer rental planning starts with matching the unit to the crowd, not just picking the cheapest special event porta potty on the list.
Depends on the event and the guest list. A basic standard porta potty works fine for a construction crew or a casual backyard party, but weddings and corporate events usually want more. A deluxe flushable unit adds a flush handle and a nicer interior, and it rents for 85 to 1200 dollars a day depending on features. For a real step up, a restroom trailer gives guests running water, mirrors and climate control. Our 2 stall trailer suits smaller gatherings, while the 4 stall or 8 stall models handle festivals and county fairs. Luxury events lean on our luxury restroom trailer, and trailer rentals for a single event run 2499 to 3899 dollars depending on size and duration. If you need showers too, ask about our shower trailer rental. Every unit we deliver needs about 60 feet of clear straight approach behind the truck, so tell us if your Casper venue has tight access, gravel drives or grass that gets soft after rain.
Do I Need Handwashing Stations at My Event?
Yes, if you are serving food or drinks. 29 CFR 1910.141(d)(2) requires washing facilities stocked with soap and towels or a hand-drying device, and hand sanitizer alone does not satisfy that standard. Most caterers and food trucks in Casper ask for at least one handwashing station near the serving area, and a portable sink rental works well next to a beer garden or dessert table. If your event includes painting booths, henna, or anything using coatings or similar contaminants, OSHA 1926.51(f)(1) calls for washing facilities in those specific contexts too. For most parties a simple hand sanitizer station covers general guest use, but pair it with real handwashing near food. Check our handwashing requirements page if your event has a health inspector visiting, which is common for festivals and county fairs. We can bundle handwashing stations with your restroom order so everything arrives on the same truck, same trip, same setup crew.
Where Should Restrooms Go at an Outdoor Event?
Level, stable ground close to guest flow but away from food service. ADA Standards section 302.1 requires floor and ground surfaces to be stable, firm and slip resistant, so avoid soft grass or loose gravel for the accessible unit especially. Leave 36 inches of clear path per ADA Standards section 403.5.1 for the accessible route, and make sure the accessible unit itself has a 60 inch turning circle inside per ADA Standards section 304.3.1. If your event sits near Hartrandt, about 4.8 miles northwest of Casper, or out toward Red Butte, 6.7 miles southwest, tell us the venue address early so we can plan the delivery route and confirm truck access. Outdoor weddings near Mountain View, 6.8 miles northwest, often want units tucked behind a tent line but still lit for evening use. We serve venues across Casper and the small towns around it, and you can check service areas for the full list. Placement in a public right of way needs confirming with the City of Casper before delivery.
Frequently asked questions
How far ahead should I book event porta potties in Casper?
Two to three weeks is safest, especially for weddings and summer festivals when demand peaks. Rush orders happen, but you get better unit selection and delivery time slots by booking early. Check availability through our request a quote page or call ahead for large multi-day events.
What is the difference between a standard unit and an event unit?
Nothing structural, really. A standard unit is about 44 by 48 inches on the ground and stands 92 inches tall, same as any job site unit. Event pricing just reflects short-term delivery and pickup instead of a weekly service contract, and units are often cleaned before drop-off.
Can I rent just one porta potty for a small backyard party?
Yes. A single standard unit works fine for smaller gatherings and rents by the day or weekend. Weekend rates for a standard unit run higher than a single weekday but lower than a full week, so tell us your exact dates when you request pricing.
Do event restrooms need to be ADA accessible?
If you are hosting a public event, yes, at least one unit should be accessible. ADA Standards section 213.2 requires at least one accessible unit in any cluster of portable toilets, and the door opening must clear 32 inches per section 404.2.3. Private parties have more flexibility, but many hosts include one anyway.
What does porta potty event pricing actually include?
Delivery, setup, pickup and one servicing for single-event rentals. Multi-day festivals may need additional service visits, which we quote separately. Delivery fees for events typically run 100 to 540 dollars depending on distance and timing, so ask about your specific Casper address, including anywhere near Brookhurst or Vista West.
