Key facts
- A flushable unit has a foot-pump flush, a lid that covers the tank, a urinal and a fresh-water hand sink.
- It carries its own water — no hose or outlet — and gives roughly 150 flushes per fill.
- Hosts choose it for weddings, showers, graduations and guests over 70.
- For bigger crowds, pair it with standard units so the line moves.
What is a flushable porta potty?
A flushable porta potty is a portable restroom with a foot-pump flush that rinses the bowl with blue fresh water, a lid that closes over the tank, a urinal and a hand sink with soap and towels. It needs no hookups. It looks and smells more like a home bathroom than a standard unit.
“It's flushable, so that way you're not staring at nobody else's business.”
Standard, sink or flushable — which should I choose?
Choose by who is coming and how dressed-up the day is. A standard unit fits crews and casual cookouts. A sink unit fits reunions with food and kids. A flushable unit fits weddings, showers and older relatives. Hosts often mix one flushable unit for family with standard units for the crowd.

Dispatch notebook
One caller in our sample priced all three in a single call — a standard unit at $310, a sink unit at $399 and a flushable unit with sink at $500, each including delivery, setup and removal — and decided between standard and sink after asking where the unit would sit.

Is a flushable unit enough for a wedding?
For up to about 75 guests over 5 hours, two flushable units usually are. Past 100 guests, or with an open bar, add standard units or move up to an air-conditioned restroom trailer. Flushable units need no water or power, so they work in pastures and barns where a trailer can't hook up.

Questions callers asked us
How much is a flushable porta potty?
A flushable porta potty with a sink inside runs about $449–$500 per event in Tyler, including delivery, setup and removal. You get a foot-pump flush, a fresh-water sink and a toilet lid that hides the tank — or as one dispatcher put it, “you're not staring at nobody else's business.”
What is a flushable porta potty?
A flushable porta potty has a foot-pump flush that rinses the bowl with blue fresh water and a lid that covers the holding tank, plus a hand sink inside. It looks and smells more like a real bathroom. Hosts choose it for weddings, showers and older guests.
The restroom trailer I wanted is booked. What now?
Book trailers 4–8 weeks ahead in spring and fall. If yours is sold out, a flushable unit with a sink plus a hand-washing station covers most guests at a fraction of the cost. A commercial building owner in our log needed a trailer two days out and got the answer every trailer company gives in September: fully booked.
How many porta potties do I need for my party?
Plan 1 standard unit per 50 guests for a 4-hour event, 1 per 40 up to 6 hours, and 1 per 30 up to 8 hours, then add one more if alcohol is served. A 40-person party needs one unit. A 100-guest, four-hour event needs two — the same answer a caller got for her 100-guest gathering.
Will it smell?
Not if it's clean, shaded and serviced on schedule. Event units arrive washed, with fresh deodorizer in the tank. Set the unit in afternoon shade under the pines, keep the door facing away from the patio, and for longer events of 100+ guests add a mid-event cleaning.
How far ahead should I book?
Book 1–2 business days ahead for a jobsite unit, 1–2 weeks ahead for a weekend party, and 3–6 weeks ahead for weddings, races and festivals. Book 7–10 days ahead for Memorial Day, July 4th and Labor Day. Air-conditioned restroom trailers sell out first, so reserve those 4–8 weeks out.
