What's the difference between a standard unit and a deluxe flushing unit?
I'm planning a six-month office construction site rental for a crew of 25, and I'm comparing a standard unit to a deluxe flushing unit. The standard unit is the basic plastic stall with a non-flushing toilet seat over a holding tank. The deluxe flushing unit has a porcelain or plastic flushing toilet bowl that empties into a holding tank, plus a small sink with running water and a mirror.
The main difference is the experience. A deluxe unit feels more like a permanent restroom and will likely be more comfortable for the crew over half a year. But it also has more parts that can break, and the fresh water tank in the sink will need to be part of the service routine. The site has level ground and good truck access.
For a long-term rental, is the flushing feature worth the extra complexity and cost? Does the sink make a handwash station unnecessary?
