Composting toilets have been successfully installed in houses with up to four floors.<ref name=":1" /> An estimate from 2008 put the number of composting toilets in households in Germany at 500.<ref name=":5">{{cite book|last1 = Lorenz-Ladener|first1 = Hrsg.

In Germany and Austria, composting toilets and other types of [[dry toilet]]s have been installed in single and multi-family houses (e.g. Hamburg, Freiburg, Berlin), ecological settlements (e.g. Hamburg-Allermöhe, Hamburg-Braamwisch, Kiel-Hassee, Bielefeld-Waldquelle, Wien-Gänserndorf) and in public buildings (e.g. Ökohaus Rostock, VHS-Ökostation Stuttgart-Wartberg, public toilets in recreational areas, restaurants and huts in the Alps, house boats and forest Kindergartens).<ref name=":5" />

The ecological settlement in Hamburg-Allermöhe has had composting toilets since 1982. The settlement of 36 single-family houses with approximately 140 inhabitants uses composting toilets, [[rainwater harvesting]] and [[constructed wetlands]]. Composting toilets save about 40 litres of water per capita per day compared to a conventional flush toilet (10 liter per flush), which adds up to 2,044 m<sup>3</sup> water savings per year for the whole settlement.<ref>Rauschning, G., Berger, W., Ebeling, B., Schöpe, A.
