How many restrooms does a wedding need?
Guest count and bar service drive the number. A rough rule: one unit per 50 guests for a four-hour reception, more if the bar runs the whole night. A 100-guest wedding often works with two standard portable restrooms or one small restroom trailer. If you expect guests using wheelchairs or with mobility limits, plan for an accessible unit under ADA Standards section 213.2, which requires at least one accessible unit whenever units are clustered, and never fewer than one. For venues without indoor plumbing nearby, a 2 stall restroom trailer or 4 stall restroom trailer covers most backyard and barn weddings around Boulder. Larger receptions, past 150 guests, usually need an 8 stall restroom trailer to keep lines short during toasts and the first dance. Our guide on unit counts breaks this down further by guest count and event length. If your venue sits outside city limits, check our service area page for towns like Louisville, 9.4 miles southeast of Boulder, and Lafayette, 10.1 miles east, both common wedding venue markets.
What does wedding porta potty rental cost in Boulder?
Pricing depends on unit type, guest count, and how upscale the reception needs to feel.
| unit | duration | low | typical | high |
|---|---|---|---|---|
| standard | event | 200 | 400 | 800 |
| deluxe | week | 150 | 250 | 290 |
| ada | weekend | 199 | 240 | 300 |
| trailer | weekend | 900 | 2000 | 3000 |
| trailer | event | 2499 | 3500 | 3899 |
Delivery and service fees are billed separately from the unit rate; see wedding porta potty rental cost for how those add up, or check rental per day pricing if your wedding runs a single day. Couples renting for a full weekend, rehearsal through brunch, should ask about the weekend rate rather than paying for three separate days. For barn weddings or estate venues, a luxury restroom trailer or deluxe flushable unit reads better in photos than a standard unit near the dance floor. If your budget is tight, a porta john rental tucked behind a tent still meets guest needs without the trailer cost.
Why rent a restroom trailer instead of standard units?
Trailers give guests real stalls, running water, and mirrors, which matters when the reception has an open bar and a dress code. A shower trailer rental also works for multi-day wedding weekends where the wedding party is staying onsite near Boulder. Standard units still make sense for tented receptions on a working farm or ranch; see farm and agricultural restrooms for that setup. Whichever you choose, placement matters: ADA Standards section 302.1 calls for stable, firm, slip-resistant ground, which rules out soft lawn without a leveling pad. Doorways need at least 32 inches of clear opening under ADA Standards section 404.2.3, and the accessible path itself needs a 36 inch minimum clear width per ADA Standards section 403.5.1. Weddings held on private land near Erie, 13.9 miles east of Boulder, or Broomfield, 15.5 miles southeast, should confirm placement with the property owner and with Boulder Porta Pros ahead of delivery, since trailer setup needs level, accessible ground and nearby power.
How far in advance should I book a wedding porta potty rental?
Book as soon as the venue and date are set, ideally 60 to 90 days out for peak wedding season. Popular weekends near Boulder fill trailer inventory fast. Waiting until the final month often means settling for standard units instead of the trailer you wanted.
Does wedding porta potty rental include delivery and setup?
Delivery and service fees are separate from the unit rental itself. Boulder Porta Pros handles placement, leveling, and pickup after the event. Ask about weekend delivery timing if your rehearsal dinner happens the night before the wedding.
Can I rent just one nice restroom trailer for a small wedding?
Yes. A single 2 stall restroom trailer works well for weddings under 75 guests, especially outdoor ceremonies with a short reception. It costs less than a multi-stall trailer while still giving guests a real sink and mirror.
Are standard porta potties okay for a formal wedding?
They can work if dressed up and placed away from the reception area. Many couples add a handwashing station rental nearby, since standard units do not include running water. A portable sink rental solves this without the trailer cost.
