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 enclosure and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scale of the project depends on your existing bathroom footprint, your style choices, and whether you want to expand the shower's footprint beyond the original tub's position.
On a technical level, the work involves rerouting the existing tub drain and supply lines, lifting the tub itself 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 shower drain. New moisture barrier is installed before any finish material goes on. Plumbing is modified to serve the new showerhead height and any body sprays, handheld wands, or rain heads you choose.
The outcome is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete improvement to your bathroom's structure and usability.
