Spas, swimming pools, and saunas are spaces to which we turn in search of positive experiences, especially healing and sanitation. What characterizes all of these spaces is a requirement to wear little clothing--or even none at all--meaning that these spaces have very different expectations regarding nudity, privacy, and the human body when compared to other forms of architecture. From the point of view of design, nudity requires specific spatial conditions, forcing architects to think carefully about details such as the opacity of materials and the dimensions of space. With this in mind, this week we present a selection of the 15 best images of healing spaces, captured by renowned photographers such as Kevin Scott, Clément Guillaume, and Marcello Mariana.
