What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and hardware — is demolished and replaced with a professionally installed shower unit. The complexity of the project varies based on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's position.
On a technical 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 constructing the new shower base with a correct slope toward the center drain. New moisture barrier is installed before any finish material goes on. Plumbing is rerouted to accommodate the new showerhead height and any extra spray features you add.
The result is a structurally sound shower that performs reliably for many years. A tub to shower conversion done right is not just a cosmetic change — it is a complete transformation to your bathroom's infrastructure and finish.
