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 enclosure and plumbing fixtures — is removed and replaced with a professionally installed shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the project 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 framing the new shower base with a proper slope toward the drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes up. Plumbing is rerouted to serve the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The outcome is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough transformation to your bathroom's infrastructure and finish.
