The Thetford Cassette toilet is a semi portable integrated toilet system for caravans
and motor homes. The unit is available in either right hand or left hand versions,
depending on which side the cassette (waste tank) has to slide in and out as viewed
from the seated position (see indication on packaging). It is recommended that the
toilet is fitted together with a shower pan that has an upturned flange (see diagram
1). The flange fits between the two ribs under the base of the toilet to avoid shower
leakage. The toilet can also be installed without a shower pan.
