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 drain assembly — is taken out and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom footprint, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's space.
On a mechanical level, the work involves capping the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then constructing the new shower base with a code-compliant slope toward the center drain. New moisture barrier is installed before any tile, stone, or prefab panel goes on. Plumbing is adjusted to fit the new showerhead position and any additional fixtures you choose.
The finished product is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a visual change — it is a complete transformation to your bathroom's structure and usability.
