How many portable toilets do I need?
Count your workers or guests, then apply the OSHA standard. For construction, OSHA 1926.51(c)(1) requires 1 toilet facility for 20 workers or fewer; 1 toilet seat and 1 urinal per 40 workers from 21 to 200; and 1 toilet seat and 1 urinal per 50 workers at 200 or more. For a wedding, festival or event restroom rental with guests, divide total attendance by 75 as a starting point. A standard unit holds 60 to 70 gallons before it needs service and sits about 44 by 48 inches on the ground. West Covina sites often need 2 to 4 units during active work. Call to discuss your headcount and we'll recommend the right setup. See our guide on how many porta potties you need for more detail.
What does OSHA require for job site restrooms?
OSHA 1926.51(a)(1) mandates an adequate supply of potable water at all places of employment. Toilets follow the ratio in the section above. If your crew is applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities where employees can remove harmful contaminants. Read our full page on OSHA portable toilet requirements for compliance steps. West Covina Porta Pros delivers units that meet every OSHA standard. We also rent handwashing stations with soap and towel dispensers, meeting 29 CFR 1910.141(d)(2) on washing facilities. A handwashing station is required, not optional, if painters or spray applicators work on your job.
How often do portable toilets get cleaned?
A baseline service interval under ANSI/PSAI Z4.3, the portable sanitation service standard, is one visit per week for up to 10 users over a 40-hour work week. Higher-traffic sites need more frequent service. We service West Covina job sites mid-week and before Monday mornings. Weekly porta potty rental includes one scheduled pump-out and restocking. Emergency service is available if a unit fills faster than expected. Visit how often porta potties are cleaned to learn what happens during a service call.
Do porta potties really smell?
Yes, if not serviced. A full tank smells worse than a maintained one. Odor depends on temperature, usage rate and whether the tank includes enzymes to break down waste. West Covina Porta Pros stocks units with deodorant and enzyme treatment. Service keeps odor minimal between visits. A deluxe flushable porta potty has a smaller holding tank than a standard unit, so it requires more frequent service but maintains a fresher environment. Read do porta potties smell for the full story.
How do portable toilets work?
A standard portable toilet is a self-contained unit about 44 by 48 inches on the ground and 92 inches tall. Waste drops into a 60 to 70 gallon tank below the seat, which sits roughly 92 inches high. Deodorant and water mask odor and dissolve waste. A vacuum truck pumps the full tank at your site or takes the unit to our facility. The tank is rinsed, restocked with water and deodorant, and returned. See how porta potties work for details on pumping. For events or construction lasting months, a restroom trailer with multiple stalls and flushing toilets offers comfort closer to a permanent facility.
What's the difference between a standard and deluxe unit?
A standard porta potty rental is ventilated, has a simple seat and lid, and works for most jobs. A deluxe unit includes a flushable bowl, larger mirror, hand sanitizer dispenser and often a skylight. Deluxe units cost more but feel less like camping. Both hold the same tank size and need the same service schedule.
Can I rent a portable toilet for just one day?
Yes. We offer daily porta potty rental for events, emergency repairs and short-term needs. Delivery and service fees apply. Weekend rates are higher than weekday rates for short rentals.
Is an ADA accessible toilet required?
If your event or job site is open to the public or employs people with disabilities, yes. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent, and never fewer than one, must be accessible. An ADA accessible porta potty has grab bars, a wider door, and a 60-inch turning circle to meet ADA Standards sections 404.2.3 and 304.3.1.
Do you rent dumpsters and other equipment besides toilets?
Yes. West Covina Porta Pros rents roll-off dumpsters, temporary fence, storage containers and handwashing stations. A 10-yard dumpster works for small renovations; 20-yard and 30-yard options suit larger jobs. A roll-off needs about 60 feet of straight clearance behind the truck for safe placement. Call or visit our service areas page to confirm delivery to your West Covina location.
