What the conversion includes
This is construction, done once and done correctly. We remove the tub and surround, reframe the opening, relocate the drain and valve where the design calls for it, and build the new shower on a certified Schluter or Wedi system with an engineered slope. The pan gets flood-tested before any tile goes on. Tile, fixtures, and frameless glass complete it, and one written workmanship warranty covers all of it.
What we usually find behind the tub
A platform tub that has sat unused for 15 years has almost always been leaking somewhere small the whole time, usually at the deck joint or where the surround meets the wall. Demolition is the first honest look anyone has had at that framing. When we find rot or a soft subfloor, we document it, price the correction in a written change order, and fix it before the new system goes in, because building a new shower over old damage wastes the entire investment.
