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 scope of the project is shaped by your existing bathroom layout, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's space.
On a structural level, the project involves disconnecting the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a correct slope toward the center drain. New waterproof liner is installed before any tile, stone, or prefab panel goes on. Plumbing is adjusted to serve the new showerhead location and any additional fixtures you add.
The finished here product is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a thorough upgrade to your bathroom's infrastructure and finish.
