Renovating a guest bathroom often feels like a battle against unreliable plumbing, but the American Standard Champion 4 turns that frustration into a non-issue. I was immediately impressed by the sheer power of the 4-inch piston action Accelerator flush valve, which handles heavy use without the typical stutter of standard models.

The sleek, white surface of the Cadet Touchless feels noticeably smoother than standard porcelain thanks to the integrated EverClean technology that fights grime.

I found the flexibility of the sensor placement particularly clever. You can mount the compact module on the wall or directly on the tank.
