A chemical toilet may be practical and (still) the standard in camper bodies from Bürstner, Globetrotter, Eriba, Adria, Ahorn and Co. However, a deliberate retrofit of a dry separation toilet, such as a Trelino in L, for a somewhat more conscious approach to business, is usually possible without any problems. We removed the chemical toilet, closed the inlet and outlet so that dismantling is possible at any time, and installed the separation toilet.
