For a construction crew of 20 or fewer, OSHA 1926.51(c) calls for 1 toilet, so 1 unit covers it. For events, plan on 1 standard portable toilet per 50 guests for a 4 hour event, more if you are serving alcohol. Cypress Porta Pros builds every quote around headcount, hours and site type, not guesswork.
OSHA 1926.51(c) sets the baseline: 1 toilet facility for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass 20, dropping to a ratio of 1 per 50 once the crew hits 200 or more. A 15 person framing crew in Cypress needs 1 unit. A 45 person site straddles the second bracket and needs 2 toilet seats plus urinals. Multi-week jobs usually run standard porta potty rental units on a weekly service cycle, and ANSI/PSAI Z4.3 sets the baseline service interval at once a week for up to 10 users over a 40 hour week, so bigger crews need either more units or more frequent pumping. Add potable water per OSHA 1926.51(a)(1) if the site has no other source. If your crew is spraying coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities beyond a toilet, which is where a handwashing station rental earns its keep. Check the full bracket table on OSHA portable toilet requirements before you order.
| Guests | Event length | Standard units | Notes |
|---|---|---|---|
| 50 | 4 hours | 1-2 | add 1 if alcohol served |
| 100 | 4 hours | 2-3 | add 1 ADA unit |
| 250 | 6 hours | 5-6 | add 1-2 for alcohol |
| 500 | 8 hours | 10-12 | multi-day adds 20 percent |
A wedding of 100 guests over 4 hours in Cypress lands at 2 to 3 standard porta potty rental units, plus one accessible unit under ADA Standards section 213.2, which requires at least 5 percent of clustered single-user units to be accessible, and never fewer than one. Serving beer or wine pushes fluid intake up, so add a unit for every 50 to 75 guests past the first hundred. Multi-day festivals should add units for each additional day rather than relying on faster service alone; see festival restroom rental and county fair restrooms for layouts that have worked at similar headcounts. For a wedding specifically, wedding restroom rental covers deluxe and trailer options side by side.
Take a 35 person remodel crew working an 8 week schedule near downtown Cypress. Under OSHA 1926.51(c), 35 workers sit in the 20-to-40 bracket, so the job needs 1 toilet seat and 1 urinal. Cypress Porta Pros would spec one standard porta potty rental unit with weekly service, and if the crew is applying exterior paint at any point, OSHA 1926.51(f)(1) requires added washing facilities for that phase, met with a portable sink rental or a handwashing station rental. Standard unit rentals in this range run in the same band whether the job is in Cypress proper or out toward Jersey Village, 10.3 miles southeast. Budget details live on porta potty rental cost and monthly porta potty rental if the job runs past a month.
A 300 guest outdoor wedding reception running 6 hours with an open bar needs more than the base ratio. Start from 5 to 6 standard units for headcount, add 2 for the alcohol service, and add 1 ADA unit to satisfy ADA Standards section 213.2. That puts the order near 8 to 9 units, or a swap to a multi-stall option like the 4 stall restroom trailer or 8 stall restroom trailer if the venue prefers fewer footprints on the lawn. Weekend event pricing for a single deluxe unit falls in a different band than a weekday rental, so check event restroom rental for how duration changes the math before you commit to a headcount.
Yes. Alcohol increases bathroom trips per guest, so add roughly 1 extra standard unit for every 50 to 75 guests once drinks are flowing, on top of the base per-guest ratio. A 4 hour dry event and a 4 hour open bar event with the same headcount are not the same order. This matters most for concert restroom rental and golf tournament restrooms bookings in Cypress, where bar service runs the full event window rather than a single reception hour. Multi-day events compound this, since day two starts with tanks already partly full from day one, so extend service frequency rather than hoping the same units stretch across three days unattended.
Dumpster sizing runs on yards, but yards convert to both cubic feet and rough tonnage depending on debris type. A 10 yard dumpster holds about 10 cubic yards, and if you are asking how many cubic feet are in a 10 yard dumpster, that works out to roughly 270 cubic feet, enough for a single room cleanout; see 10 yard dumpster rental. How many cubic feet are in a 20 yard dumpster comes out close to 540 cubic feet, and how many tons a 20 yard dumpster holds runs typically 2 to 3 tons of mixed debris depending on material, detailed on 20 yard dumpster rental. As for how many feet a 20 yard dumpster measures, expect roughly 22 feet long by 8 feet wide on most models. A 30 yard dumpster runs about 810 cubic feet, and how many tons a 30 yard dumpster can hold comes out to roughly 3 to 4 tons for a heavier remodel tear-out, covered on 30 yard dumpster rental. A 40 yard dumpster tops out near 1,080 cubic feet, and how many tons a 40 yard dumpster holds depends on material, but it handles the largest loads on a typical residential or light commercial job, per 40 yard dumpster rental. Length runs roughly 12 feet for a 10 yard box and up toward 22 feet for a 40 yard box; full dimensions by size sit on dumpster sizes and dimensions, and weight caps by material are on dumpster weight limits.
Most renovation and cleanout jobs in Cypress order both at once, since the same delivery window works for a roll-off dumpster rental and a portable toilet drop. A roll-off delivery needs about 60 feet of straight clearance behind the truck, so confirm driveway or lot access before either unit shows up. If the property has an aging septic system feeding the jobsite trailer or office, pair the order with septic pumping service, since a residential tank is typically pumped every 3 to 5 years depending on tank size and household load. Homeowners tackling a single-family remodel often start at home renovation porta potty for the restroom side and construction dumpster rental for debris, then bundle delivery with Cypress Porta Pros to cut the number of truck trips to the site.
Plan on 2 to 3 standard units for a 4 hour event with 100 guests, plus 1 accessible unit under ADA Standards section 213.2. Add a unit if alcohol is served. Multi-hour events past 6 hours should add one more unit regardless of headcount, since tank capacity becomes the limiting factor before guest count does.
OSHA 1926.51(c) requires 1 toilet for crews of 20 or fewer, then 1 toilet seat and 1 urinal per 40 workers up to 200, dropping to 1 per 50 above that. A 25 person crew and a 39 person crew both sit in the same middle bracket, needing 1 toilet seat and urinal.
ANSI/PSAI Z4.3 sets a baseline of once a week for up to 10 users across a 40 hour week. Heavier use, hot weather or events with alcohol shorten that interval. Cypress Porta Pros schedules service based on actual headcount and job length, not a fixed calendar date.
Yes, if you are clustering multiple units. ADA Standards section 213.2 requires at least 5 percent of clustered single-user toilets to be accessible, and never fewer than one, even for a cluster as small as two or three units. A single standalone unit at a small job site does not trigger this rule the same way.
A 20 yard dumpster typically carries 2 to 3 tons of mixed debris. A 30 yard dumpster carries roughly 3 to 4 tons, depending on whether the load is light construction debris or heavier material like shingles or concrete. Weight limits by material are covered on the dumpster weight limits page.
Yes. A 2 stall restroom trailer or larger multi-stall trailer often replaces 4 to 6 standard units for events with a defined footprint, like a wedding or a corporate gathering. Trailers need a level pad and often a power hookup, so confirm site access before booking one over a cluster of standard units.
