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 removed and replaced with a professionally installed shower unit. The scale of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's footprint beyond the original tub's location.
On a structural level, the work involves capping 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 floor with a correct slope toward the shower drain. New waterproof liner is installed before any finish material goes up. Plumbing is modified to serve the new showerhead location and any extra spray features you add.
The finished product 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 complete upgrade to your bathroom's structure and usability.
