Cause of loss: a corroded cast iron drain line that failed behind the wall. Style direction: boho, modern, clean.
Cast iron drain lines do not fail all at once. They corrode from the inside over decades, and a clog will often sit on top of the break for a while before anything shows in the room. That is what happened here — by the time the water appeared, it had already been finding its way into the walls, ceiling, and floor.
That is why this became a full gut rather than a repair. Once the water damage reached the structure, drying and replacing the failed pipe had to come before any of the finish work, and at that point the room was already open.
What went back in makes better use of a small footprint than the original did. The old cast iron tub became a tub-shower combination with a half-glass grid panel, so there is no curtain to close. White subway tile keeps the walls bright and easy to clean, black hexagon floor tile adds contrast underfoot, and the papered ceiling does the decorative work in the one place a small bathroom has room to spare.
