What Really 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 depends on your existing bathroom layout, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's position.
On a structural level, the project involves capping the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a proper slope toward the drain. New waterproof liner is laid down before any finish material goes up. Plumbing is modified to accommodate the new showerhead location and any extra spray features you add.
The outcome is a structurally sound shower that functions properly for many years. A tub to shower conversion done right is not just a surface-level change — it is a fundamental transformation to your bathroom's structure and usability.
