What concealed damage was found elsewhere in the remodel?
We found leaking old plumbing elsewhere in the same remodel. The work called for another trip into the crawl space to repair the leak and for another new section of subfloor.
At that stage, plumbing repair and tub installation were upcoming tasks, with completion of waterproofing planned afterward. Those were work-in-progress plans, not a completed bathroom handoff.
A plumbing leak and bathroom waterproofing are separate concerns. Repairing a leaking pipe addresses the supply or drainage system involved. Waterproofing protects the wet-area assembly from water during use; it does not repair a concealed pipe leak.
This is why finish selections cannot settle the entire scope of a whole-home remodeling project. Opening existing construction can expose repair needs that were not visible when tile, fixtures, and room layouts were selected.
