Does this toilet fit a standard 12-inch rough-in?

Yes. It is built for a 12-inch rough-in, the common spacing between the finished wall and the drain center. Measure yours before ordering, since a rear-flush toilet needs the drain behind the bowl.

Is it really ADA compliant?

The manufacturer states a 19-inch seat height with the included seat, which meets the ADA range for accessible toilets. Confirm the finished floor height after installation, since tile and thresholds can change it.

How much water does it use per flush?

It uses 1.28 gallons per flush through a rear siphonic flush. That is the current federal maximum for new toilets and lower than older 1.6 GPF models.

Is the seat included?

Yes. A soft-close seat is included with the toilet. The lid uses an under-lock design.

Can it replace a standard floor-outlet toilet?

No. This is a rear-flush model, so the drain must exit through the wall behind the bowl. A standard floor-drain toilet needs a different fixture.

Is it suitable for a home bathroom?

It can work in a home, but the commercial height and rear outlet are aimed at public restrooms. Most homes use a standard 15-inch height and a floor outlet.
