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 enclosure and plumbing fixtures — is demolished and replaced with a purpose-built shower unit. The scope of the project varies based on your existing bathroom footprint, your style choices, and whether you want to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub unit and any old tile surround that was tied to it, then framing the new shower pan with a code-compliant slope toward the drain. New moisture barrier is laid down before any tile, stone, or prefab panel goes up. Plumbing is modified to serve the new showerhead location and any body sprays, handheld wands, or rain heads you choose.
The finished product is a fully waterproofed shower that performs reliably for decades. A tub to shower conversion done correctly is not just a visual change — it is a fundamental improvement to your bathroom's structure and usability.
Top Benefits of a Tub to Shower Conversion
