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 surround and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scale of the project varies based on your existing bathroom plumbing configuration, your design preferences, and whether you need to expand the shower's footprint beyond the original tub's location.
On a structural level, the process involves capping the existing tub drain and supply lines, taking out the tub itself and any old tile surround that was tied to it, then framing the new shower pan with a proper slope toward the shower drain. New waterproof liner is laid down before any surface covering goes in. Plumbing is modified to serve the new showerhead position and any extra spray features you add.
The outcome is a code-compliant shower that functions properly for many years. A tub to shower conversion done correctly is not just a cosmetic change — it is a thorough transformation to your bathroom's infrastructure and finish.
