Shortly after we moved in, someone was taking a shower in our second-floor bathroom, the bottom of the shower cracked, and they didn’t notice. End result was an entire shower’s worth of water draining out the bottom of the shower, flowing about 10 feet inside the first-floor ceiling, draining down through the hole from a light fixture, across the kitchen floor, down through the kitchen floor into the basement ceiling, soaking into a bunch of exposed insulation, and making that insulation collapse onto the (concrete) basement floor.
