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 surround and drain assembly — is taken out and replaced with a custom-fitted shower unit. The scope of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's footprint beyond the original tub's location.
On a structural level, the work involves capping the existing tub drain and supply lines, taking out the tub shell and any old tile surround that was tied to it, then framing the new shower floor with a code-compliant slope toward the shower drain. New waterproofing membrane is applied before any finish material goes on. Plumbing is rerouted to serve the new showerhead location and any additional fixtures you add.
The result is a structurally sound shower that drains correctly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete improvement to your bathroom's structure and usability.
