  • K-4468: Wellworth 1.6 GPF toilet tank
  • K-4198: Wellworth elongated toilet bowl
  • K-1954: Touchless toilet retrofit kit
  • K-4636: Grip-Tight Cachet Q3 elongated toilet seat
  • PFWRWHWB: Wax ring floor mounting kit

Product Features:

  • Two-piece configuration eases installation and maintenance

  • Constructed of durable, easy to clean vitreous china
  • Installs in a floor-mounted configuration
  • Features a powerful gravity flush with Class Five technology
  • Includes a Grip-Tight Cachet Q3 toilet seat and cover

Product Technologies / Benefits:

  • Class Five: The Class Five siphon jet flushing system is designed for high-powered bulk flushing performance. Water flow is maximized with a larger than standard flush valve, which allows rapid release of water, and direct fed jets that quickly clear the bowl.
  • Touchless: Kohler Touchless toilets are the ideal no-touch flush solution - no handle means no germs either picked up or left behind. The touchless module projects an electromagnetic field through the lid of the tank, which activates the flush when a hand is placed above.

  • Overall Height: 29-1/4" (measured from bottom of base to top of tank)
  • Overall Depth: 30" (measured from back of tank to front of rim)
  • Overall Width: 18" (measured from rightmost to leftmost edge of toilet)
  • Bowl Height: 14-1/2" (measured from floor to bowl rim)

  • Water Depth (from Rim): 5-1/4"
  • Tank Width: 18" (measured from leftmost to rightmost edge of tank)
  • Tank Length: 8-1/2" (measured from back edge to front edge of tank)
  • Trapway (Discharge Passageway) Size: 2-1/8"
  • Distance Between Toilet Seat Installation Holes: 5-1/2"
