A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and drain assembly — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom footprint, your style choices, and whether you plan to expand the shower's square footage beyond the original tub's space.
On a technical level, the process involves disconnecting the existing tub drain and supply lines, removing the tub unit and any tile, drywall, or backer board that was tied to it, then framing the new shower pan with a correct slope read more toward the center drain. New moisture barrier is applied before any finish material goes up. Plumbing is modified to fit the new showerhead height and any extra spray features you add.
The finished product is a structurally sound shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental improvement to your bathroom's infrastructure and finish.
