Nobody puts restrooms on the mood board, but every planner knows the math: 150 guests, five hours, open bar — that's a 3-to-4-stall trailer, booked months before the peak-season Saturday it's needed, placed on firm ground within reach of power and water. Get that line item right and no one mentions it. Get it wrong and it's the only thing anyone remembers.
Job sites run the same discipline on a different calendar: unit counts from crew size and OSHA ratios, weekly service that actually shows up, and 28-day billing that holds steady from groundbreaking to punch list. We route both kinds of requests to independent local providers with the right equipment for the work — you describe the need once, compare written quotes, and book on your schedule. We're the routing desk, not the rental company.

Planning Numbers From the Standards
Straight from public agencies and standards bodies. Each card links to its source.
One unit ≈ 200 uses
The PSAI event table assumes a 50/50 crowd, no mid-event pumping, and each guest visiting once every four hours. Add 20–30% if it's 80°F or hotter or alcohol is served.
Hand-wash stations scale too
PSAI's minimum: 1 station for 1–10 toilets, 2 for 11–20, 3 for 21–30, 4 for 31–40, then 1 more for every 10 beyond that.
Jobsites have a legal minimum
OSHA requires 1 facility for 20 or fewer workers; 1 seat and 1 urinal per 40 workers above that; and 1 per 50 once a site reaches 200.

Why Planners and Site Supers Route Through Us
The sizing math is published
Stalls per guest, units per crew, ADA counts, service cadence — we put the standard planning ratios on every page so you can sanity-check any quote against the same numbers providers use.
Site-readiness comes first
Trailers need level ground, truck access, and power and water within reach. We ask those questions up front so quotes match your actual site — and delivery day goes the way the timeline says it should.
Two calendars, one request
Wedding-season Saturdays and multi-month construction billing are different businesses. Requests route by intent, so event providers see event work and route-service providers see site work.
How Booking Works

Send the specs
Headcount or crew size, dates, city, and what the site offers — power, water, and where the equipment would sit.
- Step 2
We route the request
It goes to independent local providers with matching inventory and availability for your dates.
- Step 3
Compare written quotes
Providers quote units, delivery, servicing, and pickup line by line. Ask what's included before you sign.
- Step 4
Delivery day, on schedule
The provider delivers in the agreed window, sets and levels the equipment, services it on cadence, and picks it up when you wrap.

Frequently Asked Questions
Are you the rental company?
No — we're a referral and quote-routing service. Independent local providers own the equipment and contact you directly to handle pricing, delivery, servicing, and pickup. Our routing is free to you.
How much does a restroom trailer cost to rent?
Weekend event rentals commonly run from several hundred dollars for a small 2-stall trailer to $2,000–$5,000+ for large or luxury units, moved by size, finish, season, and delivery distance. Wedding budgets often land in the $1,250–$3,000 range. Monthly construction rates are quoted separately. Written local quotes are the real answer.
How many stalls or units do I need?
Events: start at one stall per 50 guests for a four-to-six-hour gathering, and add roughly 20% for alcohol or longer timelines. Job sites: OSHA's construction ratios start at one toilet for crews up to 20, and the practical baseline is one unit per 10 workers per 40-hour week with weekly service. Providers will run the math from your actual numbers.
What does a restroom trailer need at my venue or site?
Firm, near-level ground with truck access (about 12 feet of overhead clearance along the route), one or two dedicated power circuits, and a water spigot within hose reach — or onboard tanks and a generator package where the site is off-grid. Flag what your site has in the request so quotes include the right equipment.
How far in advance should I book?
For May–October event Saturdays, three to six months ahead keeps your full choice of trailers — premium units are limited inventory in every market. Construction and off-season rentals can often be arranged in days to a couple of weeks. Later than that, you're choosing from what's left, not what's best.
Does using this service cost anything?
No. Routing your request is free and carries no obligation. Providers quote their own equipment and services directly to you — compare quotes, get the details in writing, and book only when you're ready.
