The other discovery…I was down in the metal-shop slash boiler room, my wife was up in the bathroom directly overhead, cleaning, and water started raining down onto the workbench and my tools along the shower/tub drain pipe.Turns out she was spraying down the wall tiles around the tub, and they are not grouted well. Water went behind them, to the floor, and down around the poorly sealed drain pipe hole, evidently.That pushed the bathroom redo up before the kitchen.
