  • Easy cleaning – clean the entire floor with a damp mop, no bending or kneeling
  • Improved accessibility – requires less space than a standard toilet, enhancing safety and comfort; adjustable bowl height meets personal preference or ADA guidelines
  • Water savings – built-in dual-flush, 1.6 / 0.8 GPF or 1.28 / 0.8 GPF saves thousands of gallons every year
