If you pass through Hayes Valley on Saturday keep an eye out for a 14-foot toilet tent, installed in the PROXY space off Patricia’s Green.

The tent, which will be free and open to the public from 10 a.m. to 3 p.m., is a public art project sponsored by Lava Mae, a local non-profit which advocates for increased access to toilets for San Francisco’s more than 7,500 homeless individuals.

The toilet tent will include blue swirls of water accompanied by audio of flushing sounds. Recordings of Lava Mae’s homeless guests discussing the daily challenges of accessing toilets and showers will also be played inside the installation.

The event is being organized as part of World Toilet Day, a global event created to raise awareness about sanitation crises.
