Hidden Shower Found Behind Leaking Bathroom Wall

Occurred on May 31, 2023 / Laguna Beach, California, USA

Info from Licensor: "Plumbing Emergency call, located in Laguna Beach CA, water leaking out the wall. Had to open it to find out the source, a clogged abandoned shower that was never plugged off at the drain. The drain still received water from the laundry and kitchen drain, and that led to a clogged, overflowing, and sealed-off shower. I snaked it and plugged the drain after."
