These materials combined give the sink or tub the strength to last a lifetime of use. Another benefit is that Kohler Enameled Cast-Iron is available in a wide variety of specialty colors to truly customize your home.

  • BubbleMassage - BubbleMassage technology pushes air through airjets positioned along the perimeter of the bath, creating thousands of bubbles for a range of physical and visual sensations. BubbleMassage tubs offer a more invigorating experience over effervescence technology.
  • Effervescence - Effervescence technology (also known as airpools or airbaths) is designed to move water and air gently through unique ports to create champagne-like bubbles that cling and envelope your skin to pamper you body.
