What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and drain assembly — is demolished and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom plumbing configuration, your design preferences, and whether you need to expand the shower's square footage beyond the original tub's location.
On a structural level, the project involves capping 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 framing the new shower pan with a proper slope toward the center drain. New waterproof liner is applied before any finish material goes up. Plumbing is rerouted to serve the new showerhead position and any body sprays, handheld wands, or rain heads you add.
The result is a structurally sound shower that drains correctly for decades. A tub to shower conversion done right is not just a surface-level change — it is a thorough improvement to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion
