What Exactly Is a Tub to Shower Conversion?

A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and hardware — is taken out and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom footprint, your style choices, and whether you want to expand the shower's footprint beyond the original tub's space.

On a technical level, the process 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 constructing the new shower pan with a correct slope toward the drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes up. Plumbing is modified to accommodate the new showerhead position and any extra spray features you add.

The outcome is a code-compliant shower that drains correctly for many years. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough transformation to your bathroom's plumbing, waterproofing, and layout.
