What Actually 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 plumbing fixtures — is removed and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom layout, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's position.
On a structural level, the process 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 proper slope toward the center drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes on. Plumbing is rerouted to accommodate the new showerhead location and any additional fixtures you add.
The outcome is a structurally sound shower that drains correctly for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough improvement to your bathroom's structure and usability.
