Bathroom remodeling in Alabama starts when the floor near the tub is soft, the tile sounds hollow, or the fan has been blowing steam into the attic for years. A mill-house bath the size of a closet fails differently from a slab bath with no way to see the trap. Describe the room you have, not a picture you liked.
On a pier cottage the tub drain is a hole through wood that has taken every splash since the house was built. The overflow weeps, the joists darken, and the vinyl on top still looks passable. On a slab the same leak wanders under the pan and shows up as a warm or stained spot in the hall. Green board behind old tile turns to powder when the grout opens.
Exhaust fans that dump into the attic soak the deck and the insulation above the tub. The roof then looks guilty when the bath was the source. Cast iron tubs hide failed gaskets. Showers added in a corner without a membrane wet the baseboard of the next room. A vanity set tight to an outside wall feeds rot into the sill whenever the mirror stays fogged.
Plumbing, fan ducting, and the wet wall belong in the same conversation. A new top on a rotten subfloor is a short story with a bad ending. If the stack is cast iron and the supply is galvanized, the pretty part of the job is not the part that will fail next. Say whether the ceiling below, or the crawl under the tub, already shows the water.
Call with the room location, the floor under it, and what feels soft. Mention plaster walls, a slab, or a crawl you can enter. Say if the fan grille is moldy and whether the attic above is damp. A Birmingham hillside bath tucked into a downhill wall is a wetter problem than a dry upstairs hall bath in a newer brick ranch. The trade needs that difference on the first call.
