What Actually Is a Tub to Shower Conversion?

The scope of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a technical level, the project involves rerouting the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, more info or backer board that was tied to it, then building out the new shower floor with a proper slope toward the center drain.

The result is a code-compliant shower that drains correctly for many years. A tub to shower conversion done correctly is not just a visual change — it is a thorough transformation to your bathroom's infrastructure and finish.
