Approximately one hundred Thorne rooms are known to exist. The Art Institute of Chicago holds 68 Thorne rooms, which originally occupied a dedicated wing but are now housed in a large room in the building's lower level. An additional 20 are held by the Phoenix Art Museum, and nine by the Knoxville Museum of Art. The remaining two are at The Children's Museum of Indianapolis, and the Kaye Miniature Museum in Los Angeles. In addition to these, a bar that Thorne auctioned off for charity in the 1950s is at the Museum of Miniature Houses in Carmel, Indiana.
