What Really 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 drain assembly — is demolished and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the work involves rerouting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then constructing the new shower pan with a code-compliant slope toward the shower drain. New waterproof liner is installed before any surface covering goes in. Plumbing is rerouted to serve the new showerhead position and any extra spray features you select.
The finished product is a structurally sound shower that performs reliably 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 structure and usability.
