What Really 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 hardware — is taken out and replaced with a custom-fitted shower unit. The complexity of the project is shaped by your existing bathroom footprint, your style choices, and whether you want to expand the shower's usable area beyond the original tub's location.

On a mechanical level, the work involves capping the existing tub drain and supply lines, removing the tub unit and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a correct slope toward the center drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes up. Plumbing is rerouted to accommodate the new showerhead position and any body sprays, handheld wands, or rain heads you choose.

The outcome is a code-compliant shower that performs reliably for many years. A tub to shower conversion done correctly is not just a visual change — it is a complete transformation to your bathroom's infrastructure and finish.
