What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a mechanical level, the work involves capping the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then building out the new shower pan with a correct slope toward the shower drain. New waterproof liner is applied before any tile, stone, or prefab panel goes up. Plumbing is rerouted to fit the new showerhead position and any additional fixtures you choose.
The outcome is a code-compliant shower that performs reliably for decades. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental transformation to your bathroom's structure and usability.
