What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and drain assembly — is removed and replaced with a custom-fitted shower unit. The complexity of the project is shaped by your existing bathroom layout, your finish selections, and whether you want to expand the shower's footprint beyond the original tub's space.
On a structural level, the work involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then constructing the new shower base with a proper slope toward the center drain. New moisture barrier is installed before any tile, stone, or prefab panel goes in. Plumbing is adjusted to accommodate the new showerhead height and any additional fixtures you add.
The result is a code-compliant shower that drains correctly for many years. A tub to shower conversion done right is not just a cosmetic change — it is a fundamental improvement to your bathroom's structure and usability.
Top Benefits of a Tub to Shower Conversion

- Structural Prep and Moisture Barrier Installation — This is widely considered the most technically demanding stage of a tub to shower conversion.

The drain area is pitched properly to prevent pooling.
