Anyone who's seen Blewett Hall is certainly aware that it hasn't always been a "hall" - that it was once a residence. Indeed, it was originally a house, built around the turn of the century for chancellor David F. Houston, and was renovated to its current state in the 1940s. As a consequence, Blewett lacks the large public bathrooms with which most of the campus's other buildings are equipped; in their place are smaller bathrooms - ones one would expect to see in a residence.

The (unmarked, though likely men's considering that its counterpart is women's) bathroom next to Blewett's "porch" (another vestige of its time as a residence) is one such bathroom. Almost certainly Washington University's smallest restroom, the Blewett men's room is also unique for its (striking) lack of a sink; presumably users of the one-toilet bathroom are supposed to wash their hands in the kitchenette sink which is off the nearby student lounge.

Unlike the nearby women's room, this bathroom does not make up in charm what it lacks in size - it is cramped and dark, with a tiny window and an antiquated-looking light switch described by at least one reviewer as "sketchy." Male Music Department bathroom patrons are advised to skip this ugly, sinkless bathroom and to use the newer (not to mention more sanitary and well-lit) bathroom in the nearby Music Classroom Building.
