Bathroom remodeling in Minnesota often starts because the bath is on an outside wall and the supply line has already frozen there. That wall is the reason to open the room, not a picture of a larger one. Fans that dump into the attic build ice dams while you shower. Mineral from wells spots every fixture you meant to keep. Old plaster baths are small and stacked over kitchens that show a leak first. Start with the freeze, the drip, or the fan.
A window over the tub is a cold pane all winter and a rot risk if the stool never dries. Tile on a mortar bed hides a tired pan. A surround that gapes swells the floor until the toilet rocks. Galvanized lines crust shut and turn a faucet swap into an open wall, which is sometimes the only chance to move that line into the warm side of the insulation. Say if the shutoff works. Say if the well is the supply.
Leak, fan, freeze, and full rework do not share a scope. A stained ceiling below means the cosmetics are over. A duct that dies in the attic puts the roof in the conversation. A cabin bath drained every fall is not a family bath used every night. If you are opening the wall anyway, say whether the line should leave the exterior bay. Closing the water may affect only this room or a whole stack. Say which.
Access is a narrow stair, a small door, and debris that has to leave on a day the steps may be ice. Waterproof the wet wall before you choose a mirror. If you only need a valve or a rocking toilet, keep the call there. Moving a drain over a slab or a shallow crawl is the large decision. A radiator or a register may be the only heat in the room, and covering it wrong makes the next freeze more likely.
Name the town and whether the bath sits on an outside wall. Say if a line there has already frozen. Minnesota will repeat that night if the pipe stays where it is. Call the number on this page.
