What Actually 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 plumbing fixtures — is taken out and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom layout, your finish selections, and whether you want to expand the shower's footprint beyond the original tub's space.

On a structural level, the work involves disconnecting 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 floor with a correct slope toward the shower drain. New moisture barrier is laid down before any tile, stone, or prefab panel goes on. Plumbing is modified to accommodate the new showerhead position and any body sprays, handheld wands, or rain heads you add.

The result is a structurally sound shower that functions properly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a thorough improvement to your bathroom's structure and usability.

Top Benefits of a Tub to Shower Conversion

New cement board or tile backer is fastened to the framing, and a full waterproofing membrane is rolled or troweled on across every area that will contact water.
