What Really 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 drain assembly — is removed and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's position.
On a mechanical level, the project involves disconnecting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then framing the new shower floor with a correct slope toward the shower drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes on. Plumbing is adjusted to serve the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The result is a code-compliant shower that performs reliably for the long term. A tub to shower conversion done right is not just a visual change — it is a complete improvement to your bathroom's structure and usability.
