C402C Cassette®

Ultra-Convenient Features Everyone Loves

A holding tank with wheels and a convenient retractable handle are just two of the features of this built-in bench style model.


  • Bench style cassette toilet
  • LED level indicator that can be installed on the left or the right
  • Electric push button for adding water to the bowl
  • Waste holding tank comes with wheels and retractable handle
  • Automatic pressure release vent ensures the waste tank is ventilated, avoiding excessive pressure


  • Filling funnel for the fresh water tank
  • Removable seat and cover for easy cleaning
  • Waste tank capacity: 5.1 gal. (19.3L)
  • Flush water tank capacity: 4 gal. (15L)
  • Waste holding tank comes with integrated no-splash pour spout

The working mechanism in the holding tank is removable so the inside of the tank is easy to clean and maintain.

Caution: Do not use stiff brushes or homemade products to clean or lubricate the valve and seal of your cassette toilet, as these will damage the seals and surfaces, causing odors to escape from holding tanks. Thetford recommends using Aqua-Clean and toilet seal lubricants.
