Frequently asked questions
How many portable toilets do I need?
OSHA 1926.51(c)(1) sets the baseline for construction sites: one toilet facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers from 21 up to 200, and one toilet seat and one urinal per 50 workers at 200 or more. Events in Joplin follow looser math: a 200-person outdoor festival needs roughly 5 to 10 units depending on how long guests stay. A standard porta potty in Joplin holds 60 to 70 gallons and runs about 44 by 48 inches on the ground, making it easy to position on construction sites or at events. Multiply your headcount by event length and divide by toilet capacity, or use our how many porta potties do I need guide for help. For construction crews that swap shifts, the count stays the same. For a multi-day event, add one more unit for safety. Call us to size your job right.
What's the difference between standard, deluxe and ADA?
A standard unit is the workhorse: basic toilet, hand soap dispenser, light ventilation. Deluxe adds a flushable mechanism, higher-end interior finishes and a foot pump for the soap. Both stand about 92 inches tall. An ADA accessible unit meets ADA Standards section 213.2, which requires at least one accessible fixture in any cluster of portable toilets. Section 403.5.1 mandates a 36-inch minimum clear width on the approach route, and section 404.2.3 sets a 32-inch minimum clear door opening. ADA units cost more but let everyone on site work safely and legally. We rent ADA accessible porta potties across Joplin and can set up portable restroom rentals for any job type.
When should I rent a restroom trailer instead?
A restroom trailer suits events over 100 people or job sites where employees stay 8 hours or longer. Unlike a portable toilet, a trailer has multiple stalls, running water, sinks and a small HVAC system. Trailers cost more upfront but they scale better. A 2-stall restroom trailer fits smaller weddings and corporate outings. 4-stall and 8-stall models work festivals, marathons and construction projects in Joplin with 200-plus people. Trailers need about 60 feet of straight clearance behind the delivery truck. Once placed, they run on temporary power and require a dedicated service call if anything breaks. Delivery fees apply. A standard portable toilet rental works for short jobs under 50 people; upgrade to a trailer when comfort and volume matter.
How often do portable toilets need servicing?
ANSI/PSAI Z4.3 sets the baseline: one service visit per week for up to 10 users over a 40-hour work week. Joplin job sites with more traffic, heat or high usage may need twice-weekly service. We pump out the tank, restock toilet paper and soap, sanitize the seat and interior, and replace the blue additive, whether it's a standard unit or deluxe flushable model. An event running one day needs service before and after. A two-week construction project gets weekly cleaning as part of our construction site services. Ask us about your schedule when you call; we'll recommend a plan that keeps the site compliant and clean.
What can't go in a dumpster?
Most construction debris, landscaping waste and household items are fine. Avoid tires, car batteries, asbestos, medical waste, paint cans, propane tanks and electronics. Joplin regulations may restrict certain materials further. A roll-off dumpster rental comes in 10, 20, 30 and 40-yard sizes. Weight limits apply, and overages incur fees. Call before dumping anything hazardous so we can guide you to the right container and disposal method; see our what cannot go in a dumpster guide for details. Joplin Porta Pros can also help with septic tank pumping if your property has a tank, grease trap pumping for commercial kitchens, or a portable handwashing station if your work site requires one under OSHA rules.
