The "Party Bathroom" is one of the works from the series titled "Catharsis Box". Within this group of artworks, Panmela Castro envisions a private space where the occurrence of something creates a moment of epiphany, spontaneity, liberation, emancipation, sovereignty, free will, and all the sensations that the artwork's proposition can invoke in the audience that isolates themselves within it. The Party Bathroom is a participatory installation, site-specific, set up in the institution's restroom. While using the bathroom, the public can tag their thoughts on mirrored walls. Despite the freedom of anonymity, the act of looking at oneself while writing raises an ethical dilemma about leaving for others what also serves you. In the end, with the walls covered in writing, you won't be able to see anymore.
