What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation 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 scale of the project is shaped by your existing bathroom footprint, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's location.
On a technical level, the work involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a proper slope toward the drain. New waterproof liner is applied before any tile, stone, or prefab panel goes up. Plumbing is rerouted to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you select.
The finished product is a code-compliant shower that functions properly for decades. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental transformation to your bathroom's infrastructure and finish.
