What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and hardware — is demolished and replaced with a purpose-built shower unit. The scope of the project varies based on your existing bathroom layout, your finish selections, and whether you want to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the project involves capping the existing tub drain and supply lines, removing the tub unit and any surrounding wall material that was tied to it, then building out the new shower pan with a proper slope toward the drain. New waterproof liner is installed before any tile, stone, or prefab panel goes in. Plumbing is rerouted to serve the new showerhead position and any additional fixtures you choose.
The outcome is a code-compliant shower that functions properly for decades. A tub to shower conversion done right is not just a surface-level change — it is a fundamental transformation to your bathroom's infrastructure and finish.
