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 professionally installed shower unit. The scale of the project varies based on your existing bathroom footprint, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a technical level, the project involves rerouting the existing tub drain and supply lines, lifting the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a proper slope toward the center drain. New waterproof liner is applied before any finish material goes up. Plumbing is adjusted to fit the new showerhead height and any additional fixtures you add.
The result is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done right is not just a visual change — it is a complete upgrade to your bathroom's infrastructure and finish.
