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 taken out and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was tied to it, then constructing the new shower pan with a correct slope toward the center drain. New moisture barrier is installed before any finish material goes on. Plumbing is rerouted to serve the new showerhead position and any additional fixtures you add.
The outcome is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a thorough improvement to your bathroom's infrastructure and finish.
