What Actually 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 plumbing fixtures — is taken out and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your design preferences, and whether you plan to expand the shower's usable area beyond the original tub's position.
On a technical 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 framing the new shower pan with a correct slope toward the shower drain. New waterproofing membrane is laid down before any surface covering goes in. Plumbing is adjusted to fit the new showerhead height and any extra spray features you select.
The outcome is a fully waterproofed shower that drains correctly for many years. A tub to shower conversion done correctly is not just a visual change — it is a complete upgrade to your bathroom's infrastructure and finish.
