Getting the unit count wrong is one of the most common and most avoidable problems at an outdoor event. Too few units and guests are standing in line before the first hour is out. Too many and the order cost runs higher than it needed to. The gap between those two outcomes usually comes down to a few questions asked before the order is placed, and that is exactly where we start.
Schmidt Porta Potty Rental handles portable restroom rentals for Des Plaines events, construction projects, and everything in between. When you call, we work through the details with you before anything is scheduled, so the unit count, the service frequency, and the delivery timing all fit the actual job. The price is confirmed on the phone before a single unit moves. Call (464) 266-9289 for a free quote.
Most people call with a headcount and expect that to be enough. It is a starting point, not an answer. What actually determines how many units an event needs is the guest count combined with how long the event runs, whether alcohol is being served, and whether all guests need accessible facilities.
A gathering of 100 people at a two-hour afternoon reception needs a different setup than the same 100 people at an all-day festival with a beer garden. For events running up to about four hours, one restroom per 50 guests is a reasonable baseline. Longer events push that number up because cumulative traffic is higher even if the crowd size stays the same. When alcohol is part of the day, plan to add roughly 10 to 20 percent more units to whatever baseline you land on.
One too few is a much worse outcome than one too many. A line that backs up in the first hour becomes a complaint that lasts all day. A unit that sees lighter use than expected is a minor cost. We help callers land on the right number before delivery is scheduled, not after the event is already underway.
Events in Des Plaines that use public parks or city-owned green space often require some form of approval before a portable restroom can be placed. The issuing authority and the process vary depending on the specific location and how the space is managed. We talk through what applies at your address before delivery is scheduled, so no unit goes in the wrong place.
Placements on commercial property or shared parking areas sometimes involve a property manager or building owner who needs to sign off on the location. It is worth confirming access and approval before the delivery date, and we can help you think through what to ask. The goal is a clean placement with no surprises on the day.
The rate is set on the phone before anything is scheduled, and it accounts for everything the rental involves. Unit type and unit count move the price in the most obvious direction, but rental duration and servicing frequency are just as important. A single unit on a one-day event and the same unit on a six-month construction site are different rentals in every way that matters.
Routine servicing covers pump-out, cleaning, sanitizing, deodorizing, and restocking paper and soap. For typical use, service visits run about twice a week. Sites with heavier traffic get more frequent visits, and that frequency is part of what gets confirmed when the order is quoted.
There are no mysteries in the process. Ask what the quote covers and you get a straight answer. Call (464) 266-9289 and we will walk through the numbers until the order fits the job.
The same rental is not the same rental everywhere. A backyard graduation party in Des Plaines calls for something different than a slab pour with a crew of 30, and both of those are different from a public event where every guest needs accessible facilities. The service page carries the full unit comparison. Here is how a few of the most common situations tend to shake out.
A job site running for weeks or months needs a unit that handles daily crew use and stays on a reliable service schedule. Standard portable restrooms cover most site configurations. High-rise and multi-story builds have their own requirements: rolling units, elevator-fit units, and crane-hoistable units put sanitation where the crew is rather than requiring a trip to ground level. Holding tanks are available for sites with no sewer connection, extending the time between service visits on remote or infrastructure-limited locations.
When guests expect something beyond the basics, deluxe flushable restrooms and restroom trailers are the right direction. Trailers with running water, climate control, and interior lighting match the setting at an outdoor wedding or a corporate event on private ground. They range from compact two-station configurations up to large multi-stall setups, depending on the guest count and the event length.
Any event open to the public should include at least one ADA-compliant unit. Larger events follow a ratio of roughly one ADA unit for every 20 units in the order. ADA-accessible restroom trailers are available for events where full accessibility is needed in a trailer format, with a lowering chassis and ramp built in. ADA and standard units for any size event means no guest is left without an option that works for them.
Same-day delivery is available for Des Plaines when the schedule allows, and next-day delivery covers most situations where the timeline is tight. For large events or multi-unit construction orders, booking a week or two ahead gives the most flexibility on placement timing and unit selection. Weekend and holiday delivery is available when the job calls for it.
Units arrive fully stocked with paper and sanitizer, ready to use from the moment they are set down. Local crews handle placement and confirm the position before leaving the site. When the rental ends, pickup is scheduled at a time that works for the project. The sooner you call, the sooner we get units on site.
A weekly or recurring market needs a unit that is serviced on a schedule that matches the market calendar. Hand-wash stations are a natural addition at food-vendor events where hygiene requirements are higher than at a standard outdoor gathering. We work out the service frequency when the order is placed.
When a utility failure, flooding, or another emergency displaces residents or shuts down infrastructure, sanitation needs to be in place fast. We deploy portable restrooms and shower trailers quickly for relief operations, and we scale the unit count as the situation develops. Holding tanks handle sites where no sewer connection is available.
High foot traffic over a full day puts real demand on sanitation. The unit count for a street festival scales with attendance and event length, and hand-sanitizer stations placed throughout the site keep hygiene accessible across a spread-out footprint. We size these orders the same way we size any other: guest count, event duration, and alcohol service all factor in.
A private backyard event in Des Plaines typically calls for one to three units depending on the guest count and how long the gathering runs. Deluxe flushable units are a popular choice when the occasion calls for something a step above the standard. We help callers land on the right count before the order is placed. Call us and we'll size the order with you.
Crews working a multi-day repair or infrastructure project need consistent sanitation access for the duration. We set up a servicing schedule that runs alongside the project timeline, and we adjust it if the job runs longer than expected. Holding tanks are available where the site has no sewer connection.
Multi-day outdoor events with large and varied attendance need a mix of standard units, ADA-accessible units, and hand-wash stations placed across the grounds. We plan the unit count around peak attendance windows and schedule servicing to keep pace throughout the event. Local accountability means we earn the next rental by doing this one right.
We deliver throughout Des Plaines and into the surrounding communities across Cook County. Mount Prospect, Park Ridge, Rosemont, Niles, and Prospect Heights are all part of our regular delivery area. If your event or project falls somewhere nearby, call and we will confirm coverage at your address before anything is scheduled. We're here when you need restrooms.
Standard portable restrooms do not include interior lighting. Restroom trailers do include interior lighting as part of their setup. If lighting is important for a nighttime event, a trailer is the right direction to look, and we can walk you through the options on the call.
Permit requirements depend on whether the unit sits on private property or in the public right of way, and the rules can vary by location within the city. We talk through what applies at your specific address before delivery is scheduled so no unit goes in the wrong place.
Yes. Seasonal properties, hunting camps, agricultural sites, and other locations that are used only part of the year are a regular part of what we handle. Call us with the address and the dates you need coverage and we will put together an order that fits the schedule.
Each unit is deodorized during every service visit, and the chemical treatment in the tank works continuously between visits to suppress odor. Proper ventilation built into the unit also helps. High-traffic sites benefit from more frequent servicing, which keeps odor under control more effectively.
There is no requirement to separate units by gender, and most event and job-site setups use a shared bank of units. If the event format or the organizer's preference calls for designated units, we can accommodate that. Call us and we will work through the layout with you.
Yes, as long as we can get clear directions to the location. Remote properties, agricultural land, and undeveloped sites without a formal address come up regularly. Give us landmarks, GPS coordinates, or detailed directions when you call and we will make sure the delivery crew can find it.
Yes. We regularly deliver to Mount Prospect, Park Ridge, Rosemont, Niles, Prospect Heights, and other communities across Cook County. If your address is in the area, call and we will confirm coverage before anything is scheduled.
For multi-unit orders tied to a specific event date, booking a week or two in advance gives the most flexibility on unit selection and delivery timing. Smaller orders for private gatherings can often be arranged on shorter notice. Call (464) 266-9289 and we will confirm what is available for your date.
Units are meant for human waste and toilet paper only. Trash, food waste, or other debris left inside creates a sanitation problem and may affect the cost of servicing. If a unit comes back with foreign material in it, that is something we address when the unit is picked up.
The price is confirmed on the call before anything is scheduled, and it covers the unit type, rental duration, and service frequency you agreed to. If the order changes, the price is updated to reflect what actually gets delivered.

| Unit | Best Suited For | Notable Features | Good to Know |
|---|---|---|---|
| Standard Portable RestroomMost Popular | Construction sites, block parties, tailgates, general events |
| The most commonly rented unit we carry. One unit covers up to 20 workers on a job site, or plan one per 50 guests for events running up to four hours. |
| Standard Restroom with Hand Sink | Farmers markets, school events, church functions, film shoots |
| A practical choice when you want handwashing built into the restroom rather than handled by a separate stand-alone station nearby. |
| Deluxe Flushable Restroom | Outdoor weddings, graduation parties, upscale gatherings |
| When a standard unit would feel out of place, this is the step up. Works well alongside restroom trailers on larger events that need a mix of unit types. |
| ADA / Wheelchair-Accessible Restroom | Any permitted or public event, mixed-ability job sites |
| Plan for at least one ADA unit on every event order, and roughly one ADA unit for every 20 units on larger orders. We carry them for any order size. |
| Rolling / Elevator-Fit Unit | Multi-floor and high-rise construction sites |
| Designed specifically for high-rise and multi-story builds across the Chicago metro where workers need access without a trip to ground level. |
| Crane-Hoistable Unit | Elevated work decks, rooftop construction, high-rise builds |
| The right call when the work deck is elevated and there is no elevator access. Keeps the crew from losing time making trips down to a lower level. |
| Trailer-Mounted Single Unit | Remote sites, frequently relocated jobs, rural properties |
| A practical solution when the job moves or when a site is too remote or irregular for a standard drop placement. |
| Restroom Trailer, 2-Station | Small weddings, private parties, intimate gatherings |
| A compact trailer that fits where a large multi-stall unit would be too much. Works well for events of 75 to 150 guests depending on event length. |
| Restroom Trailer, Multi-Station | Festivals, large weddings, corporate outdoor events, 5K races |
| High-traffic events benefit from the throughput a multi-stall trailer provides. Call us with your attendance estimate and we will recommend the right stall count. |
| Luxury / VIP Wedding Restroom Trailer | Upscale weddings, VIP sections, corporate galas, film productions |
| When the event's presentation matters as much as the logistics, these trailers deliver a guest experience that standard units cannot. Available for full event setups or VIP areas only. |
| ADA Restroom Trailer | Large events requiring accessible trailer facilities |
| The right choice when a large event needs ADA compliance in a trailer format. Pairs alongside standard restroom trailers to cover the full range of guest needs. |
| Shower Trailer / Shower-Restroom Combo | Disaster relief, remote construction crews, multi-day festivals |
| Deployed for disaster relief operations, crew camps, and any multi-day event or remote job where workers need to clean up on site. |
| Hand-Wash Station | Food-service events, school carnivals, high-traffic outdoor events |
| A strong addition to any order where food is served or where hygiene is a priority. Arrives stocked and ready to use alongside the restroom units. |
| Hand-Sanitizer Station | Event entrances, high-traffic walkways, indoor-outdoor transitions |
| Useful at entry points and anywhere guests move between areas. Works as a supplement to hand-wash stations rather than a replacement when soap and water are available. |
| Holding Tank | Remote properties, farms, pipeline sites, off-grid locations |
| We pump and service the holding tanks we place. This is not septic-tank service. It covers the portable sanitation equipment we deliver and maintain. |
| Spill-Containment Tray | Indoor placements, sensitive flooring, warehouse and facility events |
| A practical add-on when a unit is placed on a surface that cannot tolerate any moisture. Often required for indoor placements or events on finished floors. |
