Clesana C1 waterless sealing toilet with round base - seals waste in film bags, 12 V, for motorhomes and caravans
- Clesana C1 waterless toilet with round base: seals waste in barrier film bags, no water or chemicals. 12 V, standby 0.28 W, 515 x 363 x 461 mm, seat height 478 mm.
Clesana C1 is a waterless toilet for motorhomes and caravans that, at the push of a button, automatically seals waste in a tight bag made of barrier film. It needs no water and no sanitary additives, and the sealed bags go into residual waste. This version has a round base for free placement in the room. Power supply 12 V.

How it works
- press the flush button (small or large) and the waste is automatically sealed in a film bag
- the bags drop into a drawer that holds 6 single bags (2 bag chains of 3 bags)
- the system lines the bowl with new film for the next use
- a counter on the display shows how many uses remain on the inserted film liner
- optional super absorber binds liquids

Mounting on the round base
- the toilet is screwed to the floor via the base
- a rotation disc between body and base lets the toilet turn by up to 180°
- with the round base keep 225 mm from the rotation axis to the rear and side walls so the lid opens in every position
- the control panel can be relocated and integrated into bathroom furniture
- removal is done by releasing the rotation disc
