If your Seattle home was built in the sixties or seventies, there's a real chance your floor is tongue-and-groove car decking — heavy planks laid across big beams every four or five feet. Tough enough to drive a car over during construction, until decades of Pacific Northwest moisture turn it to rot under your bathroom.
We poked around under a Seattle house during a bath refresh and found it — classic rotted car decking, the kind of floor that retired early without giving notice. This is the plot twist that turns a weekend project into a structural conversation.
Modern floors use 2x10 or 2x12 joists sixteen inches on center, topped with three-quarter-inch OSB or plywood, glued and screwed so it doesn't squeak. The old car decking had charm and heft — until Mother Nature and Father Time teamed up on it.
We repaired the rotted section properly as part of the bath, which solves the rot and the squeak and puts the new shower on a floor you can stand on without wondering. Catching it early is the honest move — the floor under a remodel should be the foundation, not the surprise.
