Thetford C402C RV Cassette Toilet
The Thetford C402C RV Cassette Toilet is a popular cassette toilet because of its great design, incorporating its own bench, water tank and waste cassette. All you have to do is build the enclosure, wire it for power and create an access hatch in the side of the van for access to the cassette.
A holding tank with wheels and a convenient retractable handle are just two of the features of this built-in bench-style RV toilet. The working mechanism in the holding tank is removable, so the inside of the tank is easy to clean and maintain. An advanced level indicator display shows the levels in the waste holding tank.
To build an RV bathroom in your camper van, you could install this toilet with a compatible RV shower pan and RV shower surround, giving you a 40"L x 27"W x 66"H bathroom enclosure.
Note: This toilet can be installed with cassette access on the left or right (relative to a person seated on the toilet) for maximum versatility, choose the Right-hand or Left-hand option when you order.
