Bathroom remodeling in Manchester means either a bath carved into a mill building or a small bath in a wood house built for mill workers. The mill version has thick brick, odd risers, high ceilings, and a stack that may serve a plan the original mill never had. The house version is a tight room over a kitchen, often one bath for the floor. A leak in either becomes someone else's ceiling. Say which building and which floor.
Tile on plaster or on brick, a fan that never leaves the building, and a floor with a soft spot are common in both. In a mill, getting a tub through the corridor and the stair is its own problem. In a three-family, the stair turns and the tub does not. A window in the shower wall rots the casing. The ceiling below is the truth-teller. Look before you call the work cosmetic.
Moving a toilet off a mill riser can mean a long run and a vent that does not exist yet. Keeping the fixture put is often the sane scope. A new shower on a sloping wood floor will fail if the pan cannot drain. Galvanized branches in the older houses run rusty, and new tile will not clear them. Pressure may drop when another unit draws. Mention shared water.
Heat in a mill bath can be distant from a tall window that chills the room. A line moved to an outside wall of a wood house can freeze. If this is the only bath, it has to stay usable. Say that. Basement units near the main drain should not get a pretty bath until backup risk is understood. The Merrimack side of the mill district has more of that conversation than a North End cape does.
Describe mill or house, the floor, and any stain below. List a slow drain, a fan that dies in the wall, or a soft subfloor. Say if other units share the stack. Call the number on this page.
