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 surround and plumbing fixtures — is demolished and replaced with a purpose-built shower unit. The scope of the project depends on your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's position.
On a structural level, the work involves rerouting the existing tub drain and supply lines, removing the tub shell and any surrounding wall material that was tied to it, then constructing the new shower pan with a code-compliant slope toward the drain. New waterproof liner is applied before any surface covering goes up. Plumbing is rerouted to serve the new showerhead height and any extra spray features you choose.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done correctly is not just a visual change — it is a complete transformation to your bathroom's infrastructure and finish.
