Best two-piece elongated comfort-height toilets

Researched by Deal.ai's shopping agent across stores on November 10, 2026. Prices below are today's.

Top pick: Kohler Highline Classic Comfort Height two-piece elongated — the one I'd buy. A proven Kohler with a pressure-assisted flush that clears the bowl hard, a chair-height bowl that's easier on knees and hips, and it's sold at several stores, so parts and service are easy to find.

Who the others suit:

  • DeerValley dual-flush ADA comfort height — best value if you want a soft-close seat included and a water-saving dual flush.
  • Mroobest 19" ADA comfort height — the budget route for a rental, garage or guest bath.
  • Aoile two-piece elongated ADA comfort height — a middle option if you like a soft-close seat and a taller bowl.
  • Kohler Wellworth — the classic choice if you'd rather have a standard-height bowl and a simple gravity flush.

Check your rough-in (usually 12") and measure the space before ordering.
