What Really 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 plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scope 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 mechanical level, the work 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 constructing the new shower floor with a correct slope toward the center drain. New waterproof liner is installed before any finish material goes on. Plumbing is rerouted to serve the new showerhead position and any additional fixtures you add.
The outcome is a code-compliant shower that drains correctly for decades. A tub to shower conversion done right is not just a surface-level change — it is a complete improvement to your bathroom's infrastructure and finish.
