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 enclosure and drain assembly — is demolished and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom layout, your design preferences, and whether you plan to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, removing the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a code-compliant slope toward the shower drain. New moisture barrier is applied before any finish material goes in. Plumbing is adjusted to serve the new showerhead location and any extra spray features you select.
The finished product is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a complete upgrade to your bathroom's structure and usability.
