What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and drain assembly — is removed and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom footprint, your style choices, and whether you need to expand the shower's footprint beyond the original tub's position.
On a structural level, the process involves rerouting the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a correct slope toward the drain. New moisture barrier is laid down before any finish material goes up. Plumbing is modified to fit the new showerhead location and any extra spray features you choose.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done right is not just a visual change — it is a fundamental improvement to your bathroom's infrastructure and finish.
