Bathroom Remodeling in Claremont With Water Kept in Its Place
Claremont bathroom remodeling that keeps water in the pipes, drains and shower of an older house, with new supply lines, a tested membrane and a vented room.
In an older Claremont house, a bathroom leak seldom shows where it starts. Water that slips past worn grout or a tired wax ring travels along joists and plaster before it stains a ceiling or softens a floor. So the new room is built to hold water in 3 places only: the supply pipes, the drains and the waterproofed shower. Every joint between them is sealed, tested and left reachable where it can be.
Drains and supply lines
Once the floor and walls are open, the old pipes are judged by what can be seen. Galvanized supply lines rust from the inside and lose flow, so they are replaced with copper or PEX back to a sound fitting. A camera goes down each cast iron drain, and a cracked or scaled section is cut out and replaced with plastic pipe joined by shielded couplings. The new supply lines hold test pressure for an inspector before drywall goes up, and the toilet flange is screwed to a repaired subfloor so the wax ring seals on a level, solid base.
Steam, air and an original window
Steam is water too. A ducted exhaust fan, run through the roof or a wall to the outside, pulls moisture out before it reaches the plaster and paint. If an original window sits inside the shower, it can often stay: its sill is rebuilt to pitch toward the room and wrapped in membrane, and the sash gets tempered glass where code calls for safety glazing beside a tub or shower. Outside the wet area, moisture-resistant board and a satin or semi-gloss paint keep the rest of the room easy to wipe down, and the original door and casing go back on.

Bathroom Remodeling in Claremont: common questions
Under old tile there may be a thick mortar bed over wire lath, cast iron drains, galvanized supply pipes and, around the toilet or tub, subfloor softened by a slow leak. Old adhesive and mastic are tested for asbestos before they are disturbed. Each finding is written into the scope with what it changes, before the new floor is framed.
Yes, when the enamel and the cast iron body are sound. The tub is lifted out or protected where it sits, refinished if needed, and set back on a level bed with a new drain, overflow and valve. Membrane laps over its wall flange, so the tile edge above sheds water into the tub itself.
With one continuous membrane over the walls, the floor and any bench or niche. The floor is sloped toward the drain beneath it, seams and inside corners get reinforcing fabric, and the drain flange clamps or bonds to the membrane. Then the drain is plugged and the pan is filled for a flood test, and tile goes on only after the water level holds overnight.
