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 surround and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scale of the project varies based on your existing bathroom footprint, your finish selections, and whether you plan to expand the shower's usable area beyond the original tub's space.
On a technical level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a proper slope toward the drain. New moisture barrier is installed before any surface covering goes up. Plumbing is modified to serve the new showerhead height and any body sprays, handheld wands, or rain heads you add.
The outcome is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done by experienced hands is not just a visual change — it is a complete upgrade to your bathroom's plumbing, waterproofing, and layout.
