No gravity fall needed
The pipework doesn't need a continuous downward slope, so the bathroom can go where the floor plan wants it rather than where the drain allows.
Tiny homes and cabins
A tiny home usually can't support a conventional soil stack, and often isn't on mains water or sewer either. That is the exact problem vacuum sanitation solves.
The pipework doesn't need a continuous downward slope, so the bathroom can go where the floor plan wants it rather than where the drain allows.
If you are on a cistern, a well or a delivered tank, the toilet stops being the largest single draw in the building.
90% less water and sewage (Jets® published figure) means a far smaller holding tank, which matters when the tank has to fit under a small structure.
Specifying
This is the application where the honest answer matters most. A vacuum system costs more upfront than a gravity install, and it needs reliable power. If your cabin has a straightforward drop to a septic field and mains power, a conventional toilet is the cheaper and simpler answer and we will tell you so.
Where it pays is when you are hauling water in, pumping waste out, or physically cannot get the fall you need.

How many fixtures, how far the runs are, and what power you've got. That's enough for a real specification and a real price.
