What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its framing and drain assembly — is taken out and replaced with a purpose-built shower unit. The scope of the project is shaped by your existing bathroom plumbing configuration, your design preferences, and whether you need to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the project involves disconnecting the existing tub drain and supply lines, removing the tub itself and any tile, drywall, or backer board that was tied to it, then framing the new shower pan with a code-compliant slope toward the center drain. New waterproofing membrane is applied before any surface covering goes on. Plumbing is adjusted to accommodate the new showerhead position and any body sprays, handheld wands, or rain heads you add.
The result is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done right is not just a visual change — it is a fundamental transformation to your bathroom's plumbing, waterproofing, and layout.
