By taking daily life as subject matter while commenting on the everyday aesthetic of middle class values, Deborah Wachter's work touches various overlapping themes and strategies. Reoccurring subject matter can be recognized, such as the relation with popular culture and media, working with repetition, provocation and the investigation of the process of expectations.

Deborah Wachter's work is often about contact with architecture and basic living elements. Energy (heat, light, water), space and landscape are examined in less obvious ways and sometimes developed in absurd ways. Many of Deborah Wachter's paintings are characterized by using everyday objects in an atmosphere of middleclass mentality in which recognition plays an important role. Different rules apply than in everyday life and even everyday objects undergo transubstantiation.

Deborah Wachter's art often refers to pop and mass culture. In a search for new methods to ‘read the city’, she focuses on the idea of ‘public space’ and more specifically on spaces where anyone can do anything at any given moment: the non-private space, the non-privately-owned space, space that is economically uninteresting.
