Get the condition down in writing
Location, how long it’s been an issue, any relationship to weather, and how it’s changed all matter. Photos and rough measurements speed up the first conversation.
Read the Local 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.
Ask what gets covered up
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. The written scope should explain exactly what gets prepared and checked before it’s no longer visible.
Compare the whole scope, not one number
Protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranty terms, and change-order rules should all be part of the comparison.
What official local sources add
Little of this framework reaches an interior bathroom, and it is worth saying so plainly. The exception is scale: on a parcel inside a Special Flood Hazard Area, work extensive relative to the structure's value engages Chapter 32's standards. What actually shapes a Grand Rapids bathroom project is the housing era beneath the framework — Heritage Hill and the older near-downtown neighborhoods carry bathrooms carved out of bedrooms and landings long after the house was built, with drain routing that reflects each of those alterations.
