What Really 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 plumbing fixtures — is taken out and replaced with a custom-fitted shower unit.

On a technical level, the process involves rerouting the existing tub drain and supply lines, taking out the website tub shell and any surrounding wall material that was tied to it, then framing the new shower floor with a correct slope toward the shower drain. New moisture barrier is applied before any finish material goes up. Plumbing is adjusted to accommodate the new showerhead position and any extra spray features you add.

- Framing, Waterproofing, and Substrate Work — This is widely considered the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is screwed to the framing, and a continuous waterproof layer is rolled or troweled on across all wet surfaces. The shower pan is pitched properly to avoid standing water.
