What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its framing and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scope of the project is shaped by your existing bathroom footprint, your style choices, and whether you want to expand the shower's footprint beyond the original tub's location.
On a structural level, the project involves disconnecting the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then building out the new shower pan with a code-compliant slope toward the center drain. New moisture barrier is applied before any finish material goes in. Plumbing is rerouted to accommodate the new showerhead height and any extra spray features you select.
The outcome is a structurally sound shower that drains correctly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a thorough transformation to your bathroom's infrastructure and finish.
