What Really 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 professionally installed shower unit. The scope of the project is shaped by your existing bathroom footprint, your style choices, and whether you want to expand the shower's square footage beyond the original tub's location.
On a structural level, the process involves capping the existing tub drain and supply lines, taking out the tub shell and any surrounding wall material that was tied to it, then building out the new shower pan with a proper slope toward the drain. New waterproofing membrane is installed before any finish material goes on. Plumbing is modified to serve the new showerhead height and any extra spray features you choose.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a fundamental improvement to your bathroom's structure and usability.
