What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and drain assembly — is taken out and replaced with a professionally installed shower unit. The scale of the project depends 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 structural level, the project involves disconnecting the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a proper slope toward the drain. New waterproofing membrane is laid down before any finish material goes in. Plumbing is rerouted to serve the new showerhead position and any extra spray features you add.
The outcome is a code-compliant shower that performs reliably for the long term. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough transformation to your bathroom's plumbing, waterproofing, and layout.
