Thetford C403L RV Cassette Toilet

This is a special-order item. The current lead time for this item is 4-6 weeks. 

The Thetford C403L RV Cassette Toilet is a popular cassette toilet because of its great design, incorporating its own bench and waste cassette. Unlike the Thetford C402C, it does not come with its own water tank, so you can plumb it into the RV water supply, build the bath enclosure, wire the toilet 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. Thetford service door sold separatelyThis is a large item and must ship via truck freight, shipping is $149.
