What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and drain assembly — is demolished and replaced with a professionally installed shower unit.

On a structural level, the process involves capping the existing tub drain and supply lines, taking out the tub itself and any surrounding wall material that was tied to it, then building out the new shower base with a proper slope toward the drain. New waterproof liner is installed before any tile, stone, or prefab panel goes on. Plumbing is adjusted to serve the new showerhead location and any extra spray features you add.
