What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is taken out and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom layout, your design preferences, and whether you want to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a correct slope toward the drain. New moisture barrier is applied before any tile, stone, or prefab panel goes on. Plumbing is modified to fit the new showerhead location and any additional fixtures you choose.
The outcome is a code-compliant shower that performs reliably for decades. A tub to shower conversion done correctly is not just a visual change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
