Start with conditions, not a product
What determines whether the room lasts is behind the tile: drain location, framing, how waterproofing transitions are detailed, ventilation, electrical capacity, and access all shape the actual scope.
Build a complete scope
- Existing conditions and likely cause
- Preparation and protection
- Materials, compatibility, and installation details
- Permits, testing, cleanup, and restoration
- Exclusions, warranty terms, and change-order process
Grand Rapids Context
A bathroom original to that furniture-era housing boom was typically a single small room built for one fixture layout, plumbed to the standards of whichever decade -- 1840s through early 1900s -- the home actually dates to, and a remodel in one of Grand Rapids' older homes usually has to work around that original layout rather than assume a modern one.
