How Much Is It to Rent a Porta Potty? The Day Rate Is the Wrong Number to Multiply

A standard portable toilet rents for $75 to $200 per day, $100 to $350 per week, or $100 to $300 per month with one service visit per week included, according to A Royal Flush's September 2026 price guide for Connecticut, New York and New Jersey. Zters' April 2026 national guide puts the same three periods at $75 to $175, $150 to $300, and $125 to $275. The month is not thirty times the day, because a portable toilet is priced by truck trips rather than by calendar time: delivery and pickup run $50 to $100 per trip, and every additional service visit is billed on top of the base rate.

Why $150 a day and $150 a month are both real prices

Those two figures sit side by side in nearly every price list, and the day rate is the one people carry into a budget. Thirty days at $150 is $4,500, for a month the same company quotes at $220.

Nothing about the unit changes between the two quotes; what changes is how many times a truck visits your site. A single-day rental buys two trips, a drop and a pull, compressed into 24 hours, and the driver is paid for both before anyone uses the toilet. A month buys those same two trips plus four scheduled service visits, so the trip cost spreads across 28 days instead of one.

That is why long rentals look implausibly cheap beside short ones. Zters puts a national week at $150 to $300 against a national day at $75 to $175, so seven days cost about what two days cost. Before booking a Friday and a Saturday, ask what the full week costs.

The same standard unit, three markets

| Line item | Northeast (A Royal Flush, Sep 2026) | Los Angeles (EasyWM, Jan 2026) | Houston (Zters location page) | |---|---|---|---| | Standard, per day | $75–$200 | $145–$330 (day or weekend) | n/a | | Standard, per month, weekly service | $100–$300 | $200–$515 | $200–$220 construction, $210–$220 event | | ADA unit | n/a | $200–$515/month | $305–$325/month | | Handwashing station | n/a | $100–$350/week | $210–$225/month | | Delivery and pickup | $50–$100 per trip | included; $50–$150 same-day | ~$98 average | | Extra service visit | $75–$150 | $50–$200 | n/a |

The regional spread is wider than the spread between unit types. A standard unit at the top of the Los Angeles monthly range costs more than an accessible unit at the top of the Houston range, which makes a national average close to useless as a budget input. Quote your ZIP code, not your country.

The service cycle that sets the price

A standard non-flush unit holds 60 gallons. PolyJohn's March 2024 product instructions for the PJN3 series list the holding tank at 60.0 gal (227 liters) and the assembled unit at 165 pounds on a standard base. The Portable Sanitation Association International states the working figure directly: these units "support about 200 uses before they need to be cleaned."

Run the jobsite arithmetic. Ten workers, four visits each per working day, five days: 200 uses. One tank, one week, one pump-out. The weekly service visit is not a vendor habit; it is what tank volume and a typical crew produce when multiplied, and it is why the monthly rate holds steady while the day rate looks expensive.

The consensus standard reaches the same place from the other direction. ANSI/PSAI Z4.3, the workplace portable sanitation standard sold through the ANSI webstore and given free to PSAI members, sets one toilet facility per ten employees, and its 2016 edition allowed one per fifteen where units were serviced more than once a week. Unit count and service frequency trade directly against each other, and both land on the invoice. The 2024 revision reorganizes the requirement around cumulative labor hours, calling for one non-flush toilet per ten workers and one handwashing facility per twenty where cumulative hours fall under 400, with servicing at least once every seven days. Ask which edition your vendor quotes from; the answer changes the unit count.

OSHA leans on that schedule rather than writing its own. Its letters of interpretation on 29 CFR 1926.51(c) treat the ANSI Z4.3 servicing timetable as one acceptable way of showing toilets are kept sanitary, and a toilet in unsanitary condition is not counted as provided at all.

How many units a site actually needs

Events: guests multiplied by hours

The ratio in general circulation is one unit per 100 guests for every four hours, traced to PSAI's special events chart. PSAI distributes that chart to rental customers rather than publishing the numbers on its site, so any version you find on a vendor page is a restatement rather than the source. Ask your supplier for the chart itself.

Set the ratio against the 200-use figure and something useful appears. One hundred guests across four hours generate roughly 100 uses, half a tank. Capacity is not the binding constraint. Time is. At three minutes per visit, one unit clears at most 80 visits in four hours at continuous occupancy, and real demand is not continuous, it clusters after the toasts. That arithmetic is mine rather than a standard's, and it is why vendor charts place two units on a 100-guest, four-hour event.

Two adjustments push the number up. Alcohol service adds 15 to 20 percent on most industry charts, with some suppliers going to 20 to 30 percent once the forecast passes 80°F. It is mid-afternoon in summer as I write this, blinds half down, and I have no reason to go outside; a guest standing in an open field at 88 degrees has been drinking water for three hours, and the count has to carry that. The charts also assume no pump-out during the event, the assumption most often broken at eight-hour festivals.

Construction: OSHA Table D-1 is the floor, not the target

29 CFR 1926.51(c)(1) states that toilets shall be provided for employees according to Table D-1, and the table reads: 20 or less, 1; 20 or more, 1 toilet seat and 1 urinal per 40 workers; 200 or more, 1 toilet seat and 1 urinal per 50 workers. Under temporary field conditions, provisions shall be made to assure not less than one toilet facility is available. Mobile crews with transportation readily available to nearby toilets are exempt.

The distance between that table and the ANSI ratio can change a quote by thousands of dollars over a project. Forty workers require one toilet seat and one urinal under Table D-1, and four units under Z4.3's one-per-ten. Vendors quote from ANSI, inspectors enforce OSHA, and your invoice follows the vendor. I would not argue a supplier down to the federal floor on a site where 40 people share one seat, but I would make them write the ratio they used on the quote. That ratio is the price.

The accessible unit is a share of the count, not an addition

Access Board guidance on the 2010 ADA Standards is specific: "In the case of single user portable units, access is required to at least 5% at each cluster, excluding those on construction sites for construction personnel which are fully exempt (§213.2, Ex. 3, §203.2)." California's building code closes the gap in the federal wording by requiring no fewer than one accessible unit per cluster.

Priced out, the accessible unit is not a rounding difference. Zters lists an ADA event unit at $200 to $275 per week against $150 to $200 for a standard event unit, and its Houston page shows $305 to $325 per month against $200 to $220 for a standard. Plan the accessible unit into the count from the start, because adding it late means paying a second delivery trip.

Weekend event against recurring construction service

| | Weekend event | Construction, one month | Construction, six months | |---|---|---|---| | Unit count driven by | guests × hours, PSAI event chart | Z4.3, one per ten workers | Z4.3 ratio, OSHA Table D-1 as floor | | Service visits in base rate | none (no mid-event pump-out) | 4, one per week | about 26, one per week | | Truck trips per unit | 2 | 6 | 28 | | Published rate basis | $145–$330 day/weekend (LA) | $100–$300/mo with weekly service (NE) | same monthly rate, per cycle | | Dominant cost | delivery and pickup | the weekly visit | weekly visit × cycle count | | Where money leaks | weekend windows, same-day surcharge | out-of-cycle visits, winterization | the thirteenth billing cycle |

The two products separate cleanly. A weekend rental is a delivery business with a toilet attached: two trips, no service visit, and surcharges that attach to Saturday windows and tight venue access. A recurring construction rental is a service subscription, where the unit sits still while the truck returns every seven days, so the repeating line rather than the initial drop compounds.

Comparing a rental against a purchase price answers the wrong question. The useful comparison is a weekend against a service contract.

What the headline rate leaves out

Each of these is published by a named supplier and lands on a real invoice. Delivery and pickup run $50 to $100 per trip, with an urban or difficult-access premium of $100 to $300 above standard, per A Royal Flush. EasyWM lists a same-day surcharge of $50 to $150 and public right-of-way permits at $25 to $150 in Los Angeles. Winter antifreeze treatment adds $10 to $20 per unit per billing cycle. Handwashing stations run $50 to $100 per month nationally, $210 to $225 per month in Houston, and $100 to $350 per week in Los Angeles. Houston delivery averages about $98 for a standard unit, $105 for an accessible unit, and $88 for a handwashing station.

The sources disagree on one line, and that one matters most. Zters prices an additional service visit at $30 to $60; A Royal Flush prices one at $75 to $150. A spread that wide on the item most likely to recur is reason enough to get the figure written into the quote.

I compare cross-border fragrance orders, where a buyer pays before smelling anything and the listed price is never the price that lands. I once recommended a lower-priced bottle to a Montreal buyer without checking duty and brokerage, which erased the saving at the door, and every landed-cost table I have built since opens with that line. The rental version of that mistake is the billing cycle. Pot-O-Gold Rentals, which serves Houston, bills every 28 days rather than by calendar month, and a year holds 13.04 of those cycles, not 12. At $220 per cycle, twelve months of service costs $2,860 rather than $2,640. The extra $220 lands in whichever month contains the thirteenth invoice.

Buying a unit instead: the other nearby figure

TotalRestroom's catalog lists new standard units at $929.58 for the Satellite Global, $985.92 for the Satellite Tufway, $1,033.42 for the PolyJohn PJN3, and $1,216.93 for the PolyJohn Fleet, all before freight. Accessible models run from $2,556.34 for the Satellite Liberty to $3,264.42 for the PolyJohn We'll Care. A non-heated PolyJohn handwashing sink is $622.40.

Set $1,033.42 against Houston's $200 to $220 per month and it reads as a five-month break-even. That reading is wrong, and it is the second figure people mistake for the answer. The monthly rate is mostly the visit, not the box. Four out-of-cycle visits at the Zters price of $30 to $60 come to $120 to $240, which is the whole monthly rate; at A Royal Flush's $75 to $150 they exceed it outright. Buying the unit buys plastic. It does not buy the vacuum truck, the licensed disposal of what accumulates in the tank, the driver, or the restocking. An owner of one unit hires that service anyway, at per-trip prices instead of contract prices.

Sizing and pricing a rental in four steps

1. Count peak concurrent users and the hours they are on site. For an event that is the guest count and run time, not the invitation list; for a jobsite, the largest crew present at once, not the project average.
2. Convert users into uses, then into visits. Multiply users by expected daily uses by days on site, then divide by 200. A result above 1 for the week means a second unit or a second weekly visit, and the vendor should say which they priced.
3. Price the trips rather than the days. Ask for delivery, pickup, each scheduled service visit, and any out-of-cycle visit as separate line items, with the accessible unit and any handwashing station priced individually.
4. Lay the quote over the real calendar. Count billing cycles instead of months, confirm the cycle length in days, and confirm the delivery window in writing, because a Saturday drop or a same-day request can add $50 to $150 to a price you thought was settled.

Frequently asked questions

What does it cost to rent out a portable toilet?

A standard unit runs $75 to $200 per day, $100 to $350 per week, and $100 to $300 per month with one weekly service visit included, per A Royal Flush's September 2026 Northeast guide. Zters' April 2026 national figures are close. Delivery and pickup add $50 to $100 per trip where billed separately.

What is the average cost to buy a porta potty?

TotalRestroom lists new standard units at $929.58 for the Satellite Global, $985.92 for the Satellite Tufway, and $1,033.42 for the PolyJohn PJN3, before freight. Accessible models run $2,556.34 to $3,264.42. The purchase covers the unit only; pumping, licensed disposal, and the service truck remain recurring costs.

How many portable toilets do you need for 100 people?

Two standard units for a four-hour event, plus an accessible unit for any event open to the public. The widely used PSAI ratio is one unit per 100 guests per four hours, and suppliers add the second because queueing rather than tank capacity is the limit. Add 15 to 20 percent when alcohol is served.

What does it cost to rent a porta potty for a weekend?

Expect $145 to $330 for a standard unit across a weekend in Los Angeles, per EasyWM's January 2026 guide, and $75 to $200 per day in the Northeast. A weekend buys two truck trips and no service visit, so delivery and pickup dominate the price rather than the length of the rental.

How many users, hours, and service visits does the site require?

Count peak concurrent users and hours on site, then convert to uses. A standard 60-gallon tank supports about 200 uses, per PSAI. Ten workers at four uses a day for five days reaches exactly 200, which is why weekly service is standard. ANSI/PSAI Z4.3 requires servicing at least every seven days.

Does the written quote include delivery, pickup, and consumables?

Not always. Zters and A Royal Flush both include weekly service in monthly rates, but A Royal Flush bills delivery and pickup at $50 to $100 per trip and out-of-cycle visits at $75 to $150. Ask for paper, sanitizer, winterization, and the billing cycle length to be listed as separate lines.
