Kohler Highline Tall Toilet vs American Standard Champion Toilet

The Kohler Highline Tall is the pick for anyone who needs extra seat height or wants a sleeker look; its 33-1/4-inch overall height sits about 2-1/2 inches above standard Comfort Height. The American Standard Champion is the safer bet for clog-prone households, with a 4-inch flush valve, 2-3/8-inch trapway and a 1,000-gram MAP rating, backed by a 10-year limited warranty. Both are two-piece elongated 1.28 GPF gravity toilets. The Kohler scores higher on owner ratings but draws complaints about a noisy flush; the Champion's larger rating base is more mixed, and its seat is included.

• Choose the Kohler Highline Tall if you want the tallest seat available for easier sitting and standing, or a cleaner, more modern profile.
• Choose the American Standard Champion if clog resistance matters most and you want a wide trapway, a long warranty and a seat in the box.
