Kohler Highline Arc Two-Piece Toilet vs Kohler Highline Arc Complete Solution Toilet

Both are the same Kohler Highline Arc Complete Solution toilet with a 1.28 GPF single-flush, 12-inch rough-in and a slow-close seat included. The real difference is bowl shape: the A listing is elongated, and the B listing is round-front, which fits tighter bathrooms. Pick elongated for comfort on a standard footprint and round-front for a small bath or powder room. Owners of this line praise the strong Class Five flush and complete kit; the common complaints are the plastic seat and occasional fill valve noise.

• Choose the Kohler Highline Arc elongated if your bathroom has room for a longer bowl and you want the extra seating comfort.
• Choose the Kohler Highline Arc round if you are fitting a small bath or powder room where a shorter bowl leaves more floor space.
