What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and drain assembly — is demolished and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you need to expand the shower's usable area beyond the original tub's space.
On a technical level, the project involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower base with a code-compliant slope toward the center drain. New waterproof liner is applied before any finish material goes up. Plumbing is modified to fit the new showerhead location and any extra spray features you select.
The outcome is a structurally sound shower that functions properly for the long term. A tub to shower conversion done correctly is not just a cosmetic change — it is a fundamental upgrade to your bathroom's infrastructure and finish.

- Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the wall studs, and a continuous waterproof layer is installed across the shower floor and lower walls. The drain area is sloped correctly to prevent pooling.
