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 enclosure and plumbing fixtures — is removed and replaced with a professionally installed shower unit. The scale of the project is shaped by your existing bathroom layout, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the project involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a proper slope toward the drain. New waterproof liner is installed before any tile, stone, or prefab panel goes up. Plumbing is adjusted to serve the new showerhead height and any additional fixtures you choose.
The result is a structurally sound shower that functions properly for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
