Most Portland couples rent 1 to 2 standard units per 50 guests, plus one ADA unit no matter the headcount. Standard rentals run $200 to $400 for a full event day, and a restroom trailer for a 100-person reception typically lands between $2,499 and $3,899. Budget also depends on venue access and how far the truck has to drive.
Start with your guest list, then double-check your venue's parking and driveway situation before you lock a number. For a backyard ceremony or a rented barn, event restroom rental planning usually starts at one standard unit per 50 guests, with an accessible unit added regardless of size, following the spacing logic in ADA Standards section 213.2, which requires at least one accessible unit in any cluster of portable toilets. A standard porta potty rental covers the budget tier; most couples upgrade to a deluxe flushable porta potty for anything with a photographer around. If the guest count climbs past 75 or the reception runs into evening cocktail hour, a restroom trailer rental keeps the line moving and looks a lot better in photos than a bank of plastic boxes. Couples booking a 2 stall restroom trailer for an intimate ceremony in Portland often pair it with a 4 stall restroom trailer if the reception runs long. Larger estate weddings sometimes need an 8 stall restroom trailer, especially with a bar tab that keeps people cycling through all night. Whatever you land on, run the math against our how many porta potties do I need guide before you commit, because guessing low is the mistake that ruins a reception photo timeline.
Cost depends on unit type, event length and whether the site needs extra delivery mileage. A porta potty rental cost breakdown for weddings looks different from a construction quote because event units run for a single weekend rather than weeks at a time, and pricing reflects that.
| unit | day | weekend | event |
|---|---|---|---|
| standard | $100-$350 | $125-$400 | $200-$800 |
| ada | $200-$400 | $199-$300 | - |
| trailer | $175-$2,500 | $900-$3,000 | $2,499-$3,899 |
A standard unit rented for a Saturday-only ceremony in Portland often runs a flat weekend rate rather than a daily one, and most venues near Dunthorpe or Lake Oswego request delivery the afternoon before so the site is ready for florists and rental crews. Add a porta john rental or two near the parking area if your venue is spread across a large lawn, since guests walking a long distance in heels do not appreciate a single restroom bank tucked far from the tent. For couples comparing a wedding restroom trailer against stacking standard units, check restroom trailer rental cost side by side with the porta potty rental per day numbers before deciding. Delivery fees for events sit separately from the unit price, generally $100 to $500 for a single-day drop depending on distance and access.
Placement matters more at weddings than almost any other event type because guests notice smell, sightlines and walking distance all at once. Keep units off the ceremony sightline but within a short, level walk, ideally on a paved or gravel pad, since ADA Standards section 302.1 requires stable, firm, slip-resistant ground for the accessible unit's approach. Leave 36 inches of clear path per ADA Standards section 403.5.1 and make sure any accessible unit has a door opening of at least 32 inches, per ADA Standards section 404.2.3. Delivery trucks need roughly 60 feet of straight clearance behind them to unload a roll-off or trailer unit, so tell your coordinator early if the driveway has a tight turn or a gate. Rural venues outside Portland, including properties near Happy Valley about 14.1 miles southeast or Hillsboro at 17.8 miles west, should confirm gravel or grass load limits before delivery day. For a full walkthrough on where units belong relative to tents, parking and food service, see our porta potty placement guide. If your venue sits inside city limits, check with Portland before final placement, since siting in a right-of-way or shared lot is not verified here and needs a direct call to the city.
Yes, if any guest or vendor might need one, and it is good practice regardless. ADA Standards section 213.2 sets the baseline: at least one accessible unit per cluster, even for small gatherings. Most venues require it in their vendor contracts anyway.
Book 60 to 90 days out for peak wedding season, sooner for restroom trailers since inventory is limited. Popular Saturday dates near Lake Oswego or Tigard fill fastest.
Yes. A luxury restroom trailer adds finishes like real sinks, mirrors and climate control, priced closer to the higher end of the trailer event range.
Sometimes, depending on the venue and whether units sit in a public right-of-way. Confirm directly with Portland; see our porta potty permit requirements page for what to ask.
A single standard porta potty rental works for very small gatherings under 25 guests, though most couples still add an ADA unit for courtesy and compliance.
