Book a porta potty at least 3 business days ahead for weekend events from May to October. Book 1 to 2 weeks ahead for July 4th, Memorial Day and Labor Day weekends and for June to September wedding Saturdays. For urgent needs, same-day delivery is available Monday to Saturday when you call before 12 noon.

Lead time depends on the season, the day of the week and the type of unit. This guide shows how far ahead to book a porta potty in Shelton and across Connecticut.

How far ahead should you book a porta potty?

How far ahead to book a porta potty depends on the date. Most weekday orders deliver the next business day. Weekend events from May to October need 3 or more business days of notice. Holiday weekends and summer wedding Saturdays need 1 to 2 weeks, because units and trucks fill up fast.

June to September wedding Saturday1 to 2 weeks
Restroom trailer, any summer weekend1 to 2 weeks
Emergency (septic, plumbing, no water)Same day, call before noon

Why do holiday weekends book up early?

Holiday weekends book up early because many parties, reunions and town events land on the same 3 days. July 4th, Memorial Day and Labor Day are the busiest weekends of the year. Booking 1 to 2 weeks ahead locks in your units, and free cancellation runs until 48 hours before delivery.

Holiday Monday pickups move to Tuesday. A unit dropped Friday before Labor Day is picked up the Tuesday after. See event porta potty rental for large gatherings.

Can you get a porta potty the same day?

Same-day porta potty delivery is available Monday through Saturday when you call before 12 noon. A same-day rush fee may apply, and the fee is quoted upfront before you book. Same-day service covers emergencies like a failed septic system, a plumbing shutdown or a supplier who did not show.

Call (475) 326-5810 as early in the day as you can. See same-day porta potty rental for how it works.

How does the weekend delivery rule work?

Weekend events get a Friday drop-off and a Monday pickup, or Tuesday after a holiday Monday. The extra days are not charged. Phones and dispatch are open Monday to Saturday, 7 AM to 7 PM. Book a Saturday party by midweek to get a Friday delivery.

For a summer Saturday party, call by Tuesday of that week. That gives 3 business days before the Friday drop-off. The backyard party porta potty checklist walks through the rest of the plan.

How far ahead should a construction site book?

A construction site can usually book a porta potty for next-business-day delivery. Billing runs on a 28-day cycle with weekly service included. Book a few days ahead for several units, hand-wash stations or a set delivery morning. A framing crew's first day is a good example.

There is no long-term contract. The rental renews each cycle until you call or text for pickup. See construction porta potty rental and wedding restroom rental for the two busiest booking types.

What if your plans change after you book?

Plans that change after you book a porta potty are easy to handle with notice. Cancellation is free up to 48 hours before scheduled delivery. Inside 48 hours, a trip fee may apply. Adding units, swapping to a wheelchair-accessible unit or adding a hand-wash station is simplest a few days ahead.

Weather is the most common reason plans shift. If a rain date is likely, mention it when you book so the quote covers both dates.

Long-term rentals have no contract. Call or text for pickup when the job ends to stop billing at the end of the current 28-day cycle.

What should you have ready when you book?

When you book a porta potty, have 6 details ready. You need the address, dates, head count, unit types, the spot and any gate width or code. With these, most quotes go out within 15 minutes during business hours, itemized with unit, delivery, pickup, service and tax.

  • Delivery address (an intersection alone is not enough)
  • Event date or project start and end
  • Guest count and hours, or crew size
  • Unit types and number of hand-wash stations
  • Placement spot, gate width and any gate code
  • Name and phone for the driver's call-ahead
