How Many Restrooms Does a Wedding Need?
Guest count drives the number, not the venue size. A backyard ceremony in Lakewood for 60 guests can often run on two standard porta potty rental units, while a reception near 150 people usually calls for a 4 stall restroom trailer or larger. OSHA 1926.51(c) sets construction-site ratios (one toilet per 20 workers), which does not apply directly to a private event, but it is the closest published benchmark planners use to sanity-check a headcount. Our how many porta potties do I need guide walks through the math by guest count and bar service. For anything with formalwear and a photographer, skip the bare-bones unit. A deluxe flushable porta potty adds a flush handle and a hand sink, and it still fits in a tight side yard the way a trailer sometimes can't. If the venue has a raised lawn or gravel path, check our porta potty placement guide before you commit to a spot, because a trailer needs level, firm ground to sit right, per ADA Standards 302.1 on stable surfaces. Guests with mobility needs matter too. ADA Standards 213.2 requires at least one accessible unit in any cluster, so if you're renting three or more standard units, plan on an ADA accessible porta potty rental as part of that count, not an afterthought.
What Does Wedding Porta Potty Rental Cost?
Cost depends on unit type and how many days you need it on site. A single standard unit for a weekend wedding in Lakewood typically runs $125 to $400, and an ADA unit for the same window runs $199 to $300. Trailers cost more but look and feel like real restrooms, which matters when guests are in heels and suits.
| unit | duration | typical price |
|---|---|---|
| standard | weekend | $250 |
| ada | weekend | $240 |
| standard | week | $200 |
| deluxe | week | $250 |
| trailer | weekend | $2,000 |
| trailer | event | $3,500 |
Delivery is usually separate. Expect a delivery fee in the $125 to $540 range for a weekend booking, on top of the unit itself. Our porta potty rental cost page breaks down daily versus weekly math in more detail, and wedding restroom rental cost specifics cover trailer pricing if you're leaning that direction. If your venue is farther out, say near Golden 9.2 miles northwest or Wheat Ridge 5.8 miles north of Lakewood, mention that at booking so delivery gets routed correctly. A trailer delivery needs roughly 60 feet of straight clearance behind the truck, so tell us up front if the driveway curves or there's a gate.
Can I Get a Nicer Restroom Trailer for a Wedding?
Yes, and most couples do. A luxury restroom trailer or 8 stall restroom trailer gives guests running water, real mirrors, and climate control, which a standard unit can't match. These trailers use a holding system similar to the 60 to 70 gallon tank on a standard unit, scaled up per stall, so servicing intervals still matter even during a one-day event. Handwashing setup matters here too: 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at any washing station, not hand sanitizer alone, and our units are stocked to meet that. If your reception runs into evening hours, ask about lighting; a light tower rental near the restroom path keeps guests from walking blind to a barn or tent restroom setup. Couples booking a 2 stall restroom trailer for a smaller Lakewood ceremony often pair it with a portable sink rental near the catering tent, since guests wash up there more than at the restroom itself. If your venue sits close to Englewood, 10.6 miles southeast, or Littleton, 13.6 miles southeast, factor that drive into delivery scheduling since crews build routes around the day's stops. For barn and farm weddings, our farm and agricultural restrooms page covers ground conditions and setback specific to rural sites.
How far in advance should I book a wedding restroom rental?
Book 4 to 8 weeks out if you can, especially for a trailer during peak wedding season. Popular Saturdays fill fast, and trailers have fewer units in rotation than standard toilets. If you're inside two weeks, call directly rather than filling out a request a quote form, since availability changes daily.
Do wedding porta potties smell?
Not if serviced correctly. A well-maintained unit gets serviced roughly once a week under the ANSI/PSAI Z4.3 baseline interval, but for a single-day wedding, fresh units get delivered clean and don't need mid-event service. Our do porta potties smell page explains what actually causes odor.
What is the difference between a porta potty and a restroom trailer for a wedding?
A porta potty is a self-contained standalone unit, no plumbing hookup needed. A restroom trailer has real stalls, sinks, and sometimes AC, but needs a level pad and often a water or power connection. See restroom trailer rental for full specs on both.
Can I rent just one nice unit instead of a trailer?
Yes. A single deluxe flushable porta potty works well for small backyard weddings under 40 guests, especially paired with the venue's existing indoor restroom for overflow. It costs less than a trailer and still gives guests a flush and a sink.
Do you deliver restrooms to venues outside Lakewood?
Yes. We regularly deliver to Wheat Ridge, Golden, Arvada and towns nearby. Check service areas for the full list, or ask directly when you call, since exact routing depends on the venue address and delivery window.
