Flushing unit vs. a deluxe unit for a 3-day corporate retreat.
We're organizing a three-day corporate retreat for 40 people on a grassy field with good truck access. We want an upgrade from a standard unit, but the budget won't stretch to a restroom trailer. The group will have catered meals and some evening drinks. I'm weighing a flushing portable toilet against a deluxe model. The flushing unit has a foot pump and a small sink, but it needs a water supply or a tank fill. The deluxe unit has a non-flushing bowl but adds a hand sanitizer dispenser and a mirror. Both are better than basic, but I'm not sure which handles a multi-day event better without constant servicing. Which one holds up better with moderate use? Does the flushing feature make a big difference in cleanliness?
