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 taken out and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom layout, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's location.
On a structural level, the project involves rerouting the existing tub drain and supply lines, lifting the tub unit and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a code-compliant slope toward the shower drain.
