On a structural level, the work involves capping the existing tub drain and supply lines, taking out the tub unit and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a correct slope toward the shower drain. New moisture barrier is installed before any tile, stone, or prefab panel goes up. Plumbing is rerouted to serve the new showerhead height and any additional fixtures you add.
The result is a code-compliant shower that functions properly for the long term. A tub to shower conversion done right is not just check here a cosmetic change — it is a fundamental transformation to your bathroom's structure and usability.
