The TOTO Dartmouth and Whitney Universal Height Elongated Toilet Bowl is designed for use with the Eco Dartmouth ST753E 1.28gpf or Dartmouth ST753S 1.6gpf tank, as well as the Eco Whitney ST754E 1.28gpf or Whitney ST754S 1.6gpf tank. The bowl features an extra-large siphon jet, and a large trapway. The bowl is designed to feature TOTO’s Universal Height which allows for a more comfortable seat position across a wide range of users. The bowl is ADA compliant and when paired with the Eco Dartmouth ST753E 1.28gpf tank, it meets the standards for EPA WaterSense, and California’s CEC and CALGreen requirements. Additional items needed for installation and use must be purchased separately: tank, wax ring, toilet mounting bolts, water supply lines, and toilet seat.
