Bathroom remodeling in Florida is a moisture job that happens to include tile. The air is already wet. A shower that leaks into the wall does not get a dry season in which to recover. A missing membrane and a fan that recirculates or dumps into the attic are how a pretty bath becomes a soft wall. Start with the city and the room. Say whether you want a tub swapped, a shower rebuilt, or the layout actually moved. Those are different scales of work, and the drain in the slab often decides which one is realistic.
Waterproofing is the work you cannot see in the photo. A tiled wall is a finish. The layer behind it is what keeps the framing or the block from taking on water. Ask whether that layer is a sheet, a liquid membrane, or only the prefabricated surround. Ask where the curb is, how the floor slopes to the drain, and whether the valve is being replaced or reused. In a slab house, moving the toilet or the shower means opening concrete, not just shifting a fixture. Say if the house is slab, a crawl space, or a unit stacked over another unit.
Ventilation has to leave the building. A fan that wheezes into the attic loads the attic with shower moisture and hands a gift to the wood up there. If the room smells damp an hour after a shower, say so. If grout is tired but the wall is still firm, say that too. A surface refresh and a gut are not the same call. Soft material at the tub lip, a musty vanity, or tile that sounds hollow are the details that change the scope.
A curb you can step through, a seat, and grab bars that land in structure rather than in a hollow finish belong in the first conversation when you want them. Say so at the start so the floor and the blocking are part of the plan. Say which fixtures stay, which walls feel soft, and whether anyone has already opened a wall. The rest can be looked at in the room. Call the number on this page.
