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 hardware — is demolished and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom footprint, your style choices, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a structural level, the work involves rerouting the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a proper slope toward the drain. New moisture barrier is applied before any finish material goes up. Plumbing is modified to fit the new showerhead location and any additional fixtures you add.
The outcome is a code-compliant shower that performs reliably for decades. A tub to shower conversion done right is not just a surface-level change — it is a complete transformation to your bathroom's infrastructure and finish.
