Bathroom remodeling in Montana has to respect the house you actually have. A cabin bath, a mining-town bath, and a newer valley bath are not one showroom. Western moisture makes a weak fan obvious: the shower stays in the wood. Eastern houses are drier outside and still wet in the stall. The fan has to leave the building either way. Plenty of older vents end in a crawl or an attic. Find the end before you choose tile.
Wells, mineral scale, and septic systems show up as soon as you leave town water. Scale is not waterproofing. Ask what goes behind the surround and whether the alcove is square. Moving a toilet in an old floor means the joists and a drain that may already be a compromise. A prefabricated base and a tiled shower fail in different places. If a bath window has been weeping through the cold months, fix that opening in the same scope or the new wall will mark.
Layout changes are harder where the stack is buried in a log wall or a tight crawl. Say if access is from below. Say if the house is vacant part of the year, because a remodel that assumes daily heat will freeze its own traps. Adhesives want a heated house. Do not open an exterior wall into a hard night and hope. Grab bars need blocking if the only bath is a climb. A curbless opening may mean cutting the floor.
Roof leaks and bath leaks meet in mountain houses when an eave dam wets the same wall as the shower. Sort them. Tile over a damp stud bay will not care that the view is good. Keep the waterproofing conversation specific: sheet, liquid, or a prefabricated base, and how the floor slopes to the drain. A pretty fixture on a flat floor is a pond. Say the floor the bath is on and whether the laundry shares the stack.
Say the town, tub or shower, and whether the layout stays. Mention a fan into the attic or a window that ices. You do not need a drawing. You need the room and the kind of house it sits in. Call the number on this page.
