Bathroom remodeling in Charleston is rot, salt, and a fan that never reached the outdoors. Peninsula baths and island cottages are often small, damp, and stacked close to other rooms. A leak at the tub becomes a stain in the room below or a soft joist you can see from a raised crawl. Newer baths in Mount Pleasant and Summerville hide the same humidity behind a builder surround until the baseboard swells. The air here does not dry the room for you. A window painted shut is not a plan.
Say if the drain stays. Setting a new tub in the old alcove is one scope. Opening the floor for a shower, moving the toilet, or widening a door in a narrow historic room is another. Ask what sits behind the tile. A membrane is the waterproofing. Tile is only the surface you see. In this humidity, a board that is not protected will soften. Ask who sets the valve so a flush elsewhere does not scald. Floors in old houses may already be out of level. Measure before you promise yourself a curbless entry.
Walk the floor. Spongy boards mean the subfloor joins the job. From under a raised house you can often see the stain, the failed pan, and a fan duct that stops in the joists. On a slab in the outer neighborhoods, you will not see that wood, and the failure may be the pan or the trap. Ask for a ducted fan to the outside. Salt air will pit a metal medicine cabinet and a window frame in the same bath. Choose finishes that can live in that air, and say the house faces the marsh if it does.
Grab bars need wood blocking, not hope. Lowering a floor for a curbless shower in a raised cottage is a structural cut, not a cosmetic one. Write fixture swap or layout change, and write the tile and fixture choices so they stay put after demolition. If the bath sits over a piazza ceiling or a finished room, protect that room in the scope.
Say tub or shower, say whether the layout moves, and say which part of Charleston. Bathroom remodeling here is a moisture project in salt air. Call the number on this page.
