The Cadet PRO Extra Tall Elongated Toilet Bowl Only from American Standard is our tallest bowl, measuring 2½” taller than the chair-height bowl to provide optimal comfort when in use. The 19” bowl height is especially welcome as it makes it more comfortable to sit and stand, enhances access, helps with mobility concerns, and maximizes comfort for taller individuals. We recommend pairing this bowl with a Cadet PRO tank, sold separately.
