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 plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's square footage beyond the original tub's space.
On a structural level, the process involves rerouting the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then building out the new shower floor with a code-compliant slope toward the center drain. New waterproofing membrane is applied before any finish material goes up. Plumbing is rerouted to serve the new showerhead height and any additional fixtures you add.
The finished product is a structurally sound shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete upgrade to your bathroom's infrastructure and finish.
