Does this toilet need electricity?

Yes. The built-in macerating pump runs on household power, so you need an outlet near the toilet. It will not flush during a power outage.

Can it go in a basement below the sewer line?

That is its main purpose. The macerator grinds waste and pumps it through a small discharge pipe, so it can drain upward to a sewer line above the fixture.

What rough-in does it use?

It is built for a 12-inch rough-in, the common distance from the finished back wall to the drain center. Check your measurement before ordering.

Is the extra-tall height a problem for kids?

It can be. The seat sits higher than a standard toilet, which helps tall adults and people with limited mobility but is a stretch for small children.

How is it different from a standard two-piece toilet?

A standard toilet relies on gravity and a floor drain. This one adds a macerating pump and dual flush, so it costs more and needs power but works where gravity drainage is not available.
