What Really 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 hardware — is removed and replaced with a purpose-built shower unit. The scope of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you need to expand the shower's usable area beyond the original tub's space.
On a technical level, the project involves disconnecting the existing tub drain and supply lines, removing the tub shell and any old tile surround that was tied to it, then constructing the new shower pan with a correct slope toward the center drain. New waterproof liner is installed before any surface covering goes on. Plumbing is rerouted to accommodate the new showerhead location and any extra spray features you add.
The outcome is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.
